Abstract

PURPOSE:To prevent the erroneous recognition of coordinates by recognizing a point specified on a flat board plural times. CONSTITUTION:A controller for a copying machine is equipped with a control part 60 to which sensors S, a control part 100, a coordinate reader (editer) 70, etc., are connected. A lamp 62, and an optical motor 19 are controlled through an AC driver 61 and a motor control part 62. The editer 70 is constructed of a flat resistance reading directions X and Y, a pen built in a switch and an X/Y direction switching circuit 90 switching at the time of reading coordinates, and has area copying mode keys 91-98. When the editer 70 inputs coordinates, the control part 60 executes its coordinate input processing by turning on the pen switch. At that time, after reading the coordinates X and Y, the control part 60 again reads the coordinate X, and compares it with an initially read-out X signal. If they are not the same, they are handled as an invalid coordinate input. When the difference between them lies within the prescribed range, they are handled as an effective input.

Description

[Detailed description of the invention] [Technical field] The present invention relates to a coordinate input device such as a copying machine.

[Prior Art] Conventionally, when specifying an arbitrary area in an original by pressing the coordinates with a pen or the like using a separate editor (coordinate input device), the pressing force with the pen may be weak, or
If the pressing time is extremely short, accurate coordinates may not be recognized and may be recognized as incorrect coordinates.

[Purpose] The present invention was made in view of the above points, and an object of the present invention is to prevent erroneous recognition of coordinates.

In the figure, 1 is the main body of the copying machine, 2 is an image forming section centered on the photosensitive drum 18, and 7.8 is a developing device that stores toner of a different color (for example, red, black). The drum 18 is selectively brought into contact with the drum 18. Reference numeral 3 denotes a paper feeding unit for supplying transfer paper SH into the machine, which includes a cassette 9 that can be detached from the main body, their paper feeding rollers to, ti, and sensors S9 to S12. S
It consists of 22.23. Reference numeral 4 denotes an optical system including a lens system for exposing and scanning a document and forming an image on the photosensitive drum 20J, and is driven by an optical motor 19 in the direction of the arrow.

Figure 2 is a control block diagram, 101 is a main switch,
DCP is a DC power supply that supplies power to the control unit 60 and the like, S is the sensors shown in FIG. Heater 21
, 22, 63 is a motor control unit that controls the main motor 18 and optical motor 19, and HVT is a high voltage generator that supplies high voltage to the charger 13, 15, 16 and the developer 7.8. 66 is a load such as a solenoid, clutch, fan, etc.; 67 is a document processing device; 68 is a sorter; 70 is a coordinate reading device (editor); and 80 is a buzzer.

Next, the operation will be explained.

When the power switch 101 is turned on, first, the heaters 21 and 22 in the fixing device 25 generate heat, and the fixing roller waits for the temperature to reach a predetermined temperature at which fixing can be performed (wait state). When the fixing roller reaches a predetermined temperature, the main drive motor is energized for a certain period of time, and the photosensitive drum 18. The fixing device 25 and the like are driven to bring the rollers in the fixing device 25 to a uniform temperature (weight release rotation). Thereafter, the main motor 18 is stopped and the copying is possible (standby state). Here, the main motor 18 drives the photosensitive drum 20, the fixing device 25, the developing device 7.8, and various transfer paper conveyance rollers. Then, when a copy command is input from the operation unit 100, a copy operation starts.

(1) Explanation of image formation The main motor 18 rotates in response to a copy command, and the photosensitive drum 20 starts rotating in the direction of the arrow. At the same time, high voltage is supplied to the primary charger 13 from the high voltage supply device HVT and is uniformly applied on the photosensitive drum 20. zero-order exposure lamp 24 that provides a charge of
is turned on, the optical motor 19 is driven, and the original placed on the original platen 5 is exposed and scanned in the direction of the arrow, and is projected onto the photosensitive drum 207. In this way, an electrostatic latent image is formed on the photosensitive drum 20. Next, this latent image is developed by the developing device 7 or 8, and the transfer 1? The toner is transferred to the transfer paper SH at the electric device 15 and separated from the photosensitive drum 20 at the separation charger 16. Next, the cleaner 6 collects the residual toner remaining on the photosensitive drum 20, and the erase lamp 28
After the static electricity is uniformly removed, the copy cycle is repeated again. At this time, a blank exposure lamp 14 composed of an LED
(LED array) erases unnecessary charges outside the image area. Also, as will be described later, the LED array 14 includes a large number of LEDs.
It is constructed by arranging , and can erase any part of the image. First developer8. The second developing device 7 selects one of the drums 20 and 20 according to a selection command from the operation unit lOO.
is brought into contact with. In this embodiment, the first developing device 8 is filled with black toner to form the black developing device 8, and the second developing device 7 is filled with color toner to form the color developing device 7. Pressure (contact) of these developing units to the drum 20 and release thereof are performed by a black developing unit release solenoid 31 and a color developing unit pressurizing solenoid 30. When the black developer release solenoid 31 is turned on, the black developer 8 is released from the drum, and when the color developer pressure solenoid 30 is turned on, the color developer 7 is pressurized against the drum. Also, each developer 7.8 includes a black toner sensor 316. A color toner sensor S17 is arranged.

Further, a developing bias voltage is applied to the developing rollers 7-a and 8-a of each developing device from a high voltage generator HVT.

The conditions for this bias voltage are changed depending on when the black developer 8 and the color developer 7 are used in order to optimize the developing conditions for black toner and color toner. In addition, the photosensitive drum
Sensitivity may change as the durability progresses or changes in the environment occur, but in order to cope with this, the sensitivity can be changed by commands from the operation panel 100 (described later).

In addition, the copying machine of this embodiment can perform not only normal one-sided copying but also double-sided copying and multiplex copying (described later); however, the resistance value of the transfer paper once passed through the fixing device is different from that of the first side copying. The state of the transfer charger 15. has changed, and in order to deal with this, the transfer charger 15. The high voltage applied to the separation charger 16 also makes the conditions yellow for the first side, both sides, or the second side during multiple copying. The respective high voltage values for these developing biases or transfer separations are determined by commands from the control section 60.

The optical system 4 is reciprocally controlled by rotating the optical motor 18 forward and reverse via the motor control section 63 in accordance with commands from the control section 60 .

S1 C The home position sensor of the optical system stops the camera at this position during standby. S2 is an image leading edge sensor corresponding to the leading edge position of the original image, and is used for timing of copy sequence control. S3 is the limiter position (inversion position) at the time of maximum scanning. The optical system 4 reciprocates with a scan length according to the cassette size and copying magnification based on instructions from the control section 60.

(2) Control of transfer paper In the paper feed section 3 of the mountain in Fig. 1, 59 and 511 are respectively as follows.
Upper and lower paper sensors, S10.

512 are upper and lower glue lid position detection sensors, respectively;
S22 and S23 are upper and lower cassette size detection sensors, respectively.

Hereinafter, since the upper and lower stages perform similar operations, the sheet feeding operation for the L stage will be described. First, when the cassette 9 is inserted, the size detection sensor S22 reads the size and identifies the size of the cassette 9.
Turn off the paper out indicator, select the cassette size, and turn it on. Next, when a copying operation is started in response to a copy command, a middle plate raising clutch (not shown) is used to raise the middle plate in the ONL cassette 9 by one length, thereby raising the transfer paper SH by one length. The transfer paper SH rises, contacts the paper feed roller 10, reaches a predetermined height, the tray lid detection sensor S10 outputs an output, turns off the clutch, drives the paper feed roller 10, and supplies the transfer paper into the machine ( (described later). As described above, the transfer sheet in the cassette is raised by the middle plate lifting clutch, and thereafter the raised position is maintained, and the raising operation described in F is not performed at the time of starting the first copy. Further, when the number of transfer sheets in the cassette decreases during continuous copying and one side of the transfer sheet SH falls below a predetermined position a, the clutch is similarly turned on to raise it to a predetermined height.

The transfer paper fed into the machine reaches the pre-registration sensor S7, and since the registration rollers 12 are stopped, it forms a proper loop and then stops. Next, in order to align the leading edge of the image formed on the drum 20, the registration roller 12 is driven by a timing signal from the optical system 4, and after aligning the leading edge, the transfer paper is sent to the transfer section 17. In the transfer section 17 , the image on the drum 20 is transferred to a transfer paper by the transfer charger 15 , and then separated from the drum 20 by the separation charger 16 , and sent to the fixing device 25 by the paper conveyance section 17 . In the fixing device 25, the temperature sensor (not shown) placed on the surface of the fixing roller and the heater 21 control the surface of the fixing roller to a predetermined temperature. The paper is detected to be discharged in step S4, and the paper is discharged to the outside of the machine by rollers 26 and 27.

Next, manual copying will be explained.

When the manual tray 28 is moved in the direction of the arrow in the figure, the manual tray detection sensor S24 enters the ONL manual copy mode. At this time, the middle plate of the cassette 9 set in the upper stage is automatically released from the raised position, and the transfer paper SH in the cassette is lowered.

Next, place the transfer paper on the manual feed tray 28, and in response to the copy start command on the operation unit 100, the manual feed lid clutch is driven in the same way as when feeding paper from a cassette, and the transfer paper set on the manual feed tray 28 is driven. After being lifted up, the candy paper rollers 10 feed it into the machine.

Next, in the case of multiple copying, the flapper 29 is switched to the position shown by the dotted line by the operation of a solenoid (not shown), and the transferred paper, which has been fed, transferred, separated, and fixed, passes through the path 33 and passes through the second The paper is sent to the paper feed section 23. Second paper feed section 2
In step 3, after the paper is detected by the second pre-registration sensor S5, lateral positioning is performed by the transfer paper edge detection sensor S6, the lateral registration sensor S8, and the solenoid for lateral registration alignment (described later).

Next, in response to a multiple copy command from the operating section, the second registration roller 37 sends out the image again to the registration roller 12 section. Thereafter, the paper is ejected to the paper ejection tray 32 in the same manner as described above.

Furthermore, during double-sided copying, the transfer sheet is ejected halfway through by the ejection roller 27 in the same manner as in the normal copying operation described above, but after the trailing edge of the transfer sheet passes the flapper 29, the ejection roller 27 is driven in the reverse direction. , the transfer paper is guided by the flat pipe 29 and introduced into the path 33 (described later).
.

This reverse drive is performed by a solenoid that controls forward and reverse rotation. The subsequent operations are the same as in the case of multiple copying described above. In this way, in the case of double-sided copying, the ejection roller 27
The transfer paper is taken out of the machine, turned over by the reverse rotation of the roller 27, and sent to the second feeding section.

Although multiple copying of a single sheet and double-sided copying have been described above, in the case of multiple copying of a plurality of sheets or double-sided copying, the intermediate tray 40 is used. As shown in FIG. 1, the intermediate tray 40 has a paper transport path 59.4.
3 and a tray 53 for storing transfer paper in an intermediate state is provided. In the case of multiple copying of a plurality of sheets, the fused transfer paper is partially ejected by the paper ejection roller 27 under the same control as the double-sided copying of the above-mentioned one-sheet copying, and then the paper ejection roller 27 is driven in the reverse direction. Route 33.
43 and is stored in a tray 53. After repeating this operation and storing all of the first side in the tray 53, the paper feed roller 56 is driven for the second side in response to the next copy command, and copying of the second side is executed via the path 59.23. On the other hand, in the case of multiple double-sided copying, the flapper 29 passes from the fixing neck 25 through the paths 33 and 43 and is stored in the tray 53 under the same control as the first 21-ton copy.The subsequent operations are as described above. This is omitted because it is the same as in the case of multiple copies.

<Explanation of LED array> Next, the LED array will be explained.

FIG. 4-1 is a diagram showing the LED array 14 and the drive circuit, in which 60 is the aforementioned control section and 81 is five PNP transistors.

82 is connected to the anode of each LED, respectively, and 82 is connected to the anode of each LED.
A PN transistor is connected to the cathode of each LED as shown in the figure.

83 is a transistor. The LED array is composed of 124 LEDs 1 to 124, and the 124 LEDs are arranged in a line over the entire axial direction of the drum 20. Further, the length of the light emitting portion of these LED arrays is set to be longer than rlJ of the largest transfer paper. In this embodiment, two LEDs at both ends of the LED array 14,
2) The LEDs 123 and 124 are set at a portion longer than the transfer paper +1+. Each LED is driven by four LEDs 1 and 2 at both ends of the LED array.

123 and 124 are statically driven by the transistor 83, and the remaining LEDs 3 to 122 are driven by the transistor 83.
1.82, it is lit by dynamic driving of a 5 x 24 matrix.

The LED array 14 is an LED to be lit by the control unit 60.
The timing is controlled and used for removing unnecessary charges on the drum 20 and erasing an image when copying a designated area.

Furthermore, 84 in the figure is a circuit for switching the power supply voltage to the transistor 81. FIG. 4-2 is an enlarged view of the LED array 14 and photosensitive drum 20. LED array 1
The LEDs in 4 illuminate the area between A and B on the tram 20. Meanwhile, the drum 20 is rotating in the direction of arrow C. Considering the above-mentioned copy mode with area specification, the drum 20
When erasing the area after point A above, the timing signal from the control unit 60 aligns the position to point A and the LED starts to light up. That is, the LED shown in FIG. 4-2 lights up when the position of point A and point B are reached. At this time A4 and B
The product (energy) of light and time received by the drum surface at a point is small at point A and increases as it moves toward direction B. The points after the third point are the same because the LED continues to light up.

For this reason, the charge cannot be removed sufficiently at the boundary between the portion of the image to be erased and the image portion, and the boundary becomes unclear. Conversely, when the LED changes from being lit to being turned off, the image becomes unclear as well. In order to prevent this, the switching circuit 84 is driven at the time when the LED starts to turn on and when it goes out, so that the voltage normally used +
The voltage is switched to +v2, which is higher than Vt, and the amount of light emitted by the LED is increased (strong lighting).

Furthermore, although this LED array is operated by dynamic lighting as described above, five digit signals (hereinafter referred to as DG
(referred to as T signal) is taken as one unit, and the same 1131 times as the above-mentioned strong lighting time are taken. For example, in Figure 4-3, time T
The DGT signal from the external transistor 81 is turned off, and the LED is turned off. At the same time as the lighting starts at 1 Terama TO, the 5 DGT signals turn on the 0NL LEDs one after another. At this time, the switching circuit 84 selects a series of DGT signal generation times i! receiving the Jl signal from the control unit 60;
Switch to strong lighting. This strong lighting time is an integral multiple of T and is appropriately determined depending on the spread of light from the LED array 14 and the rotation speed of the photosensitive drum.

Next, I will explain the editor. The editor 70 is installed on the original pressure plate 34, and its configuration is shown in FIG.

The editor 70 includes one planar resistor for reading the positions in the horizontal direction (X direction) and the vertical direction (Y direction), and a pen with a built-in switch (not shown) that presses the surface of the editor 70 when inputting coordinates. ) and a switching circuit 90 that switches between the X direction and the Y direction when reading coordinates. The original is placed within the dotted line in the figure with the substrate position aligned with the arrow position. ” The double-sided resistor is not only in the dotted line area where the original is placed, but also in the clear key 92. Memory key 91° Area copy mode key 9
It also covers parts 3 to 98. Here, the area copy mode keys 93-98 correspond to the mode displays 132-137 on the copy panel described above. The clear key 92 is a key for clearing a specified area and canceling the area copy mode, and the memory key 91 is a key for registering a specified area. When you enter certain coordinates with a pen, 90 is sent to the relay.
1 remains OFF, a voltage is applied between Yl and YO, which is equivalent to that shown in FIG.
Next, the control unit 60 connects the relay 901 to ONL, Xl-X0
A voltage is applied between them, which becomes equivalent to the 5-2nd UA, and the coordinates in the X direction are read in the same way. The area coordinates are set based on the read coordinate data, and the sheep-human power is also interrupted.

Signal from editor t? -11 and register the copy mode and area specification coordinates. Also, when copy mode is specified, a buzzer will sound 360m5. When inputting the coordinates of area J, the buzzer is set to 30 mS. This is to remind the user of the editor input. The buzzer does not sound if the user's input to the editor is not valid.

The area for inputting coordinates of the editor area is 432x29
7mm, but considering the editor's 1 error, I set the maximum or minimum value to 5mm inside the area. That is, when specifying a point within 5 mm from the inside of the editor area, it is considered that a point 0 mm from the inside of the editor area has been specified.

Description of copy mode> Next, details of the copy mode will be described.

Mode 1. Single-sided original - double-sided copy (LED l 45 lights up) As shown in FIG. 6(a), a double-sided copy is obtained from two originals.

In other words, AFf, set the original on the document table, and press the copy key 1.
17 to form an image on one side of the transfer paper, then set the B original on the document table, and press the copy key 117 to form an image on the opposite side of the transfer paper.

Mode 2) Continuous page copying → double-sided copy (LED 146 lights up) As shown in FIG. 6(b), double-sided copies are obtained from sides A and 8 of the double-page spread document.

In other words, set the two-page spread document on the document table, and press the copy key 1.
When 17 is pressed, an image is formed on side A on one side of the transfer paper, and then an image is formed on side 8 on the opposite side of the transfer paper.

Mode 3. Single-sided original → multiple copy (LED 140 is 1-X light) As shown in FIG. 6(C), multiple copies are obtained from two originals.

In other words, set original A on the original table and press the copy key 117.
is pressed to form an image on one side of the transfer paper, then set the B original on the document table, and press the copy key 117 to form an image on one side of the A original on which the image was formed.

Mode 4. As shown in Fig. 6(d), Page 141 (LED 141 lit) is A of the original manuscript.

Make a multi-hair copy from B.1). That is, when a two-page spread document is set on the document table and the copy key 117 is pressed, an image is formed on one side of the transfer paper, and then an image is formed on the eighth side on the same side of the transfer paper.

Mode 5. Page continuous color multiplex copy (LED 1
42 lights up) As shown in 6IΔ(e), A of the double-page spread document is copied in black and 8 sides are copied in color to obtain a color multiplex copy. This is a mote that makes color copies on three sides during page continuous multiplexing. Also, side A may be a color copy.

Mode 6: A mode in which the color within the specified area is colored and the color outside the area is black.

(LED 132 lights up) As shown in FIG. 6(a), the area is obtained by color copying the white color of the designated area and black copying of the color outside the area. When you set the original, specify the area, and press the copy key, the area within the area will be imaged in black on the transfer paper. Next, a color image is formed on the transfer paper outside the area. Alternatively, copying may be performed from outside the area first.

Mode 7: A mode in which the color within the specified area is black and the color outside the area is color.

(LED 133 lights up) As shown in FIG. 7(b), the area is obtained by copying the color within the specified area to black and copying the color outside the area to color. This is the reverse mode of mote 6.

Mode 8. A mode that colors the color within the specified area. (LED 134 lights up) As shown in FIG. 7(C), the color within the designated area is copied in color. When a document is set, an area is specified, and a copy key 117 is pressed, an image is formed in color on the transfer paper within the area.

Mode 9. A mode that colors the area outside the specified area. (LED l 35 lights up) As shown in FIG. 7(d), the color outside the designated area is color-copied. When a document is set, an area is specified, and a copy key 117 is pressed, an image is formed in color on the transfer paper in the area outside the area.

Mode l O, A mode in which the color within the specified area is set to black. (LED 136 lights up) As shown in FIG. 7(e), the color within the designated area is copied to black. When the original is set, an area is specified, and the copy key 117 is pressed, an image is formed in black on the transfer paper within the area. A mode that changes the color outside the specified area to black. (LED 137 lights up) As shown in FIG. 7(f), the color outside the designated area is copied to black. When a document is set, an area is specified, and the copy key 117 is pressed, an image is formed on the transfer paper in black on the portion outside the area.

Due to the mechanism of the copying machine, the paper path has to pass through the paper path, so you cannot select only one of modes 1 to 7 listed in ``2'', single copy, continuous page copy, double-sided continuous copy 1 double-sided original → double-sided copy. .

Only one of the modes 6 to 11 can be selected because selecting two or more will result in inconsistent images. Also, 8
~11 modes and binding margin key 148/frame erase key 149
For the reasons mentioned above, you can only choose one.

When you select a mode from 5 to 11, the color selection key 120
becomes invalid. This is because modes 5 to 11 also specify the color mode for copying.

Next, a case will be described in which a document feeding device (DF, ADF, RDF) is used when mode 1 or mode 3 is selected.

(1) When using DF, when a document is set on the DF document feed tray, the document is automatically fed and set at a predetermined position on the document tray of the main body. Then, the first copying operation starts, copies are made under the set copying conditions, the transfer paper is stored in the intermediate tray 4o or the second paper feeding section 23, and the first copying operation is completed. Then, the DF discharges the original.

Next, in the same manner as described above, when the original is set on the DF's original feeding table and the original is automatically fed, the main body starts copying the second side. At this time, the transfer paper is fed from the first
Intermediate tray 4o where copying of faces is completed and stored
Alternatively, the second paper feeding unit 23 is used. When the copying operation for the second side is completed, the DF discharges the original. Then, the series of copy operations is completed.

Also, set the original manually for the first side, and set the original in D for the second side.
Alternatively, the document may be set using the DF for the first side and manually for the second side.

(2) When using the ADF, set the original on the ADF's original feed tray and press the copy key 117 to automatically feed and eject the original. When the first side of the document is completely fed, if there is no second side of the document, the transfer paper is ejected from the machine and the copying operation is completed. However, when there is only one original, depending on the copy settings,
The transfer paper is stored in the intermediate tray 40 or the second paper feed section 23, and the copying operation for the first side is completed. Then, when the copy key 117 is pressed again, the copying operation for the second side is started. At this time, you can set the original manually, or
DF may also be used.

(3) When using RDF When the copy key 117 is pressed, the RDF.

The number of originals is counted by circulating the originals set on the original feed table. Then, if there is an odd number of sheets, the last original is made a one-sided copy.

Next, paper size regulations when selecting modes 1 to 5 will be described.

When making double-sided or double-sided copies, the second
There are cases where the paper feed section 23 and the intermediate tray 40 cannot be used. If the size of the transfer paper makes it impossible to use the second paper feed section 23 and the intermediate tray 40, it is ejected from the machine and the copying operation is completed.

(1) When there is no intermediate tray 40 In the case of mode 1 and mode 3, the number of copies that can be set is "1" because originals must be replaced.

(2) Mode 1 when the intermediate tray 40 is present. In the case of mode 3, since it is necessary to exchange originals, the number of copies that can be set is limited to a certain number of copies that can be stacked on the intermediate tray.

However, if the paper size that cannot be used in the intermediate tray 40 is
When the paper size is usable in the paper feed section 23, the possible number of copies is 1°. Further, when feeding transfer paper from the manual feed tray, the intermediate tray 40 cannot be used because transfer paper of different sizes may be stacked.

Mort 1. When the intermediate tray 40 is used in a multiplex/double-sided copy mode other than mode 3, the number of copies that can be set is up to the number of sheets that can be loaded on the intermediate tray.

Kunyam processing explanation> Next, jam processing will be explained.

If a jam occurs in a copy mode that does not use the intermediate tray 40 or the second paper feed section 23, clear the jam, press the reset button S15 (shown in the first diagram), and turn on the power switch 101 to start copying. It becomes possible. Then, the copy mode returns to the one before the jam occurred. However, the number of completed copies is subtracted from the set number of copies and the remaining number of copies is displayed on the copy number display section 160. If the copy key 117 is pressed here, the remaining copy number is copied and the copying operation is completed.

If a jam occurs on the first side of the copy mode using the intermediate tray 40 or the second paper feed section 23, clear the jam, press the reset button in S15, and turn on the power switch 101 to return to a copy ready state. Become. At this time, the copy mode is the same as when the intermediate tray 40 or the second paper feed section 23 is not used. If you press the copy key 117 here, the remaining number of copies will be copied, and the first copy will be copied.
Complete the Menguchi copy operation. In a double-sided copy mode other than mode 1.3, the copying operation for the second side is then performed. The mote 1.3 performs a copying operation for the second side when the copy key 117 is pressed after exchanging the original. In addition, if the user presses the stop key 116 or the reset key 119 in the copy ready state after printing, the number of sheets of transfer paper in the intermediate tray 40 is determined. is displayed on the number-of-copies display section 160, and j
, Lj Tom, ;Konaru.

If a jam occurs on the second side of the copy mode using the paper feeder 40 or the second paper feed section 23, perform the soyam process, press S15 SET SET FUTANO, and turn on the Ichihara switch 101. The state is ready for copying.At this time, the mode returns to the copy mode where the Nyam occurred.However, the number of copies per copy display section 160 shows
Displays the number of sheets of transfer paper in 0. copy key 1 here
When 17 is pressed, the copying operation is performed until the intermediate tray 40 runs out of transfer paper. If there is no transfer paper in the intermediate tray 40 when the copying is possible after the jam has been cleared, the copying operation is completed.

Furthermore, even if the power switch is turned off when an error occurs, the data before the occurrence of an error is retained as a backup. Further, even if the front door (not shown) is opened, the supply of the 'FL source to the high voltage and the like is cut off.

Explanation of tonerless processing> Next, processing without toner will be explained.

(1) In the case of black toner, copying is not permitted in copy modes 5.6.7 and 10.11.

Even if no black toner is detected during copying, the toner out display 1 will be displayed until the set number of copies is completed.
50-1 is not displayed.

In addition, when copying using RDF, multiply the number of remaining original sheets by the desired number of copies, and if it is lOOMineko, copying will continue even if no black toner is detected during copying. To complete copying up to the last original without interrupting the process. Furthermore, if the calculation result is 100 or more, the lack of toner may affect the image, so the copying operation is interrupted when the lack of black toner is detected.

(2) When there is no color toner, copying is not permitted in copy modes 5, 6, 7, and 8.9.

During the copying operation, if the color toner becomes burnt, the copying operation is interrupted at that point. This is because if the copying operation continues, the mixture ratio of toner and carrier becomes 74, and the carrier of the color developing device adheres to the drum, causing adverse effects such as scratches on the drum. However, when the transfer paper is stored in the second paper feed section 23, the single copy mode is used, and since the amount of color toner consumed is small, a series of copy operations is completed.

When copying using RDF, the value calculated by counting the remaining number of sheets is multiplied by the value of the set number of copies. Complete copying up to the last original without interrupting the copying operation.After detecting that there is no color toner during copying of two sides of double-sided/multi-copy [1], the user turns off the power and replenishes the color toner.At that time Copying may be interrupted by removing the transfer paper stored in the intermediate tray 40 or the second paper feed section 23. Therefore, when the power switch 101 is turned on, the intermediate tray 40 or If there is no transfer paper in the second paper feed section 23, it is impossible to continue the copying operation, and the copying operation enters a standby state.

The above toner-free state processing will be explained in more detail.

8 and 9 are flowcharts regarding display and copy control in the case of no toner, and FIG. 8 shows processing in a standby state.

First, let me explain this.

The color of the developer specified by the developer selection key 120 is determined intermittently (301-1), and in the case of black copying, the developer is 301-1).
The presence or absence of toner in the developing device selected in step 02-1 is checked using a toner detection signal from a sensor (not shown);
If there is no toner, the no toner LED 150-1 lights up (
301-3), and prohibits the start of black copy and the start of two-color copy (301-4). That is, input from the copy start key 117 is not accepted. Also, if there is black toner, turn off the toner-free LED 150-1 (301-6) L, prohibiting the start of two-color copying and black copying! 301-7. Note that detection of the presence or absence of toner is performed using a well-known method. Further, even if the toner is detected to be out of toner, it does not mean that the toner is completely gone; in fact, the toner out is detected with some margin. In the case of color copying with a color developer selected, as well as black copy, if the selected color developer is out of color toner, LED150-1
301-9), color copying and two-color copying are prohibited (301-10), and if there is toner, these are canceled (301-12.13). Among these, two-color copying is the above-mentioned copy mode 5, 6.7, and is a mode in which black and color developing devices are used alternately to obtain two-color copies.

A case where the toner runs out during the next copy will be explained.

A flowchart is shown in FIG. 9, and the processing in this flowchart is checked every time one copy is executed. First, in step 302-1, it is determined whether the copy being executed is a black copy or a color copy. m in case of black copy
If it is detected that there is no toner (302-2), the set number of copies being executed is calculated (302-3). If the circulating document feeder (RDF) is not used, this calculated value will be the number of copies set using the numeric keypad 122 in the operation panel lOO, and if the RDF is used, this calculated value will be the number of copies set before copying starts. If you know in advance the number of originals to be printed, press the numeric keypad 122 on the operation unit 100.
The number will be the number of copies set in step multiplied by the number of originals.

It is determined whether the calculated total number of copies is 100 or more (302-4), and if it is 100 or more, a command to interrupt the copying is set (302-5). 303-6 determines whether there is toner,
If no toner is detected, it is determined in 302-7 whether the mode is multiple duplex or multiple copy mode using an intermediate tray, and if the mode is multiple duplex or multiple copy mode, a copy interruption command is set in 302-5. do. Also, in a mode that does not use an intermediate tray, it is possible to make double-sided or multiple copies.
In cases other than face value (302-8→302-5), a copy interruption command is similarly set. Also, if it is the first page, it will be executed without interruption. For example, if you run out of toner in multiple single-sided copy mode using a one-color developer, 302-1
→ 302-6 → 302-7 → 302-8 → 302-5, and a command is set to interrupt copying midway.

In addition, in one or more embodiments, when copying using a color developer, the copying was interrupted quickly due to the lack of color toner, but when the set number of copies to be copied is relatively small (about 3 to 5 copies), the set number of copies can be changed. It can also be configured to complete the copy. Furthermore, when copying a designated area using a color developing device, when the designated area is small, the toner consumption per sheet is small, so the number of possible sheets can be further increased.

FIG. 10 is a flowchart showing an example of this.
Connected to A in the figure. The presence or absence of color toner is determined during copying (303-1), and if toner is present, the color copy counter is cleared (303-2). Here, the color copy counter is out of toner! ,! ? This is a counter for counting the number of copies. If you run out of toner, add 1 to this color copy counter to 303.
-3), in cases other than mead that copies only the specified area, determine whether the copy counter is 5 or more in 303 to 7, and if it is less than 5, continue copying, and if it is 5 or more, 303 -9 sets the copy interrupt command and interrupts copying midway. In addition, in area copy mode I, calculate the ratio of the specified area I1 to the whole.
), if the ratio is 30% or more, perform the same process as a two-legged normal mote, and if 309≦ or less, issue a copy interruption command in 303-8 when the copy counter reaches 15 or more. .

Further, in FIG. 8, copy start is prohibited when there is no toner, but it is easy to configure such that copy start is enabled when the number of sheets is less than a predetermined number.

Note that the copy area ratio can be calculated from the size of the selected copy paper, the copy magnification, and the coordinates of the designated area.

In this way, by combining with the set developer indicator 164, the toner-free indicator 150-1 can be used for both black and color.

In addition, when toner runs out during copying, two developing devices can be implemented compactly without compromising copying operability by distinguishing whether to continue copying or to stop copying according to the developing device copy mode being used at the time. be able to.

The above toner-free state processing will be explained in more detail.

8 and 9 are flowcharts regarding display and copy control in the case of no toner, and FIG. 8 shows processing in a standby state, which will be explained first.

To judge what color the developer is specified by the developer selection key 120 described above (301-1), in the case of black copying, select 3.
The presence or absence of toner in the developing device selected in step 02-1 is checked using a toner detection signal from a sensor (not shown);
If there is no toner, the no toner LED 150-1 lights up (
301-3) and prohibiting the start of black copy and the start of two-color copy (301-4), that is,
No input from the copy start key 117 is accepted. If there is black toner, the out-of-toner LED 150-1 is turned off (301-6), and the copy start prohibition for two-color copying and black copying is canceled (301-7). Note that detection of the presence or absence of toner is performed using a well-known method. Further, even if the toner is detected to be out of toner, it does not mean that the toner is completely out; in fact, the toner out is detected with some margin. In the case of a color copy with a color developer selected, the same applies to a black copy if the selected color developer does not have color toner.

The LED 150-1 is turned on (301-9), and color copying and two-color copying are prohibited (301-10). Also, if there is toner, release these (301-12.13
). Among these, two-color copying refers to copy modes 5 and 6 mentioned above.
．． 7-t'.

This is a mode in which black and color developing devices are used alternately to obtain two-color copies.

A case where the toner runs out during the next copy will be explained.

The flowchart is shown in FIG. 9, and the process in this flowchart is checked to execute one copy. First, in step 302-1, it is determined whether the copy being executed is a black copy or a color copy. In the case of black copying, if no black toner is detected (302-2), the set number of copies being executed is calculated (302-3). If the circulating document feeder (RDF) is not used, this calculated value will be the number of copies set with the numeric keypad 122 in the operation unit 100, and if the RDF is used, this calculated value will be the number of copies set before copying starts. If the number of originals made is known in advance, the number will be the number of copies set using the numeric keypad 122 of the operation unit 100 multiplied by the number of originals.

It is determined whether the calculated total number of copies is 100 or more (30'2-4), and if it is 100 or more, a command is set to interrupt copying midway (302-5). In the case of color copying, it is determined in 303-6 whether toner is present, and if no toner is detected, it is determined in 302-7 whether or not the mode is multiple duplex or multiple copy mode using an intermediate tray, and multiple copying is performed. In the case of double-sided or multi-copy mode, a copy interruption command is set in step 302-5. Also, in a mote that does not use an intermediate tray, a copy interruption command is similarly set for cases other than the first side of double-sided or multiple copying (302-8→302-5). Also, if it is the first page, it will be executed without interruption. For example, if you run out of toner in multiple single-sided copy mode using a color developer, 302
-1→3oz-6-302-7→302-8→302-
5 and sets a command to interrupt copying midway.

In addition, in the above embodiment, when copying using a color developer, copying is immediately interrupted due to lack of color toner, but when the number of copies set is relatively small (3 to 5
It is also possible to configure the printer so that the set number of copies can be completed. Further, when copying a specified area using a color developing device, when the specified area is small, the amount of toner consumed per copy is small, so the number of copies that can be made can be further increased.

FIG. 10 is a flowchart showing an example of this.
Connected to A in the figure. The presence or absence of color toner is determined during copying (303-1), and if h-toner is present, the color copy counter is cleared (303-2).Here, the color copy counter counts the number of copies made without toner. This is a counter for If the toner runs out,
Add 1 to this color copy counter (303-3)
, If the copy counter is not mead, which copies only the specified area, it is determined in 303-7 whether the copy counter is 5 or more, and if it is less than 5, copying is continued, and if it is 5 or more, 303-7 is used.
-9 sets the copy interrupt command and interrupts copying midway. In addition, in the area copy mode, the ratio of the specified area to the whole is calculated (303-5), and the ratio is 303-5).
If it is over 0%, perform the same process as the normal mode above, and set 30%.
% or less, at 303-8, and when the copy counter becomes 15 or more, a copy interruption command is issued at 303-9.

Further, in FIG. 8, copy start is prohibited when there is no toner, but it is easy to configure the system so that copy start is allowed when the number of sheets is less than a predetermined number.

Note that the copy area ratio can be calculated from the size of the selected copy paper, the copy magnification, and the coordinates of the designated area.

In this way, by combining with the set developer indicator 164, the toner-free indicator 150-1 can be used for both black and color.

In addition, when toner runs out during copying, two developing devices can be implemented compactly without compromising copying operability by distinguishing whether to continue copying or to stop copying according to the developing device copy mode being used at the time. be able to.

Description of Editor H> FIG. 16 is a flowchart regarding the processing of human power values from the editor.

Then, the copy mode is set and canceled based on the input data (Step 4-7).

Next, Steps 4-3 to 4-7(1) will be described in detail.6 FIG. 17 is a flowchart of Step 4-3. First, turn on the buzzer (5 steps 4-3-1). Then, in that state for 30m5ec (St

As shown in 4-3 and 4-7, the time at which the buzzer sounds differs depending on the input of the copy mode and the input of the area coordinates. This is to make the user reconfirm the input mode and reduce erroneous operations. Further, as another embodiment, instead of sounding a buzzer, it is also possible to set different lighting times for nine lights, such as LEDs.

19th t9 is a flowchart showing details of 5tep4-4. Here, the length of the area coordinate range of the editor in the X direction is defined as text x, and the length in the Y direction is defined as My. First, it is determined whether the input data X in the X direction is within 5 mm from the edge of the area range (Step 4-4-1), and if it is within 5 mm, the manual data X is set to O (Step 4-4-2). .

Determine whether the input data Y is within 5 mm (S
te p4-4-3).

If it is within 5mm, set input data Y to O (S t
e p 4-4-4), human power data X is Ax-5m
If it is greater than or equal to m (Step 4-4-5), the human power data X is set to lx by 1 (Step 4-4-6). If the input data Y is y-5mm or more (Ste p4
-4-7), set input data Y to lv (S t
e p4-4-8), this is to prevent an extra image from being formed on the edge of the copy paper due to an error when specifying the edge of the editor area when specifying the area for yasking/trimming. It is.

Further, as another embodiment, when the document size can be detected (for example, a plurality of document detection sensors are provided under the document platen glass, and the document size is detected by a combination of their outputs.

), the length Ox in the X direction and the length y in the Y direction are set to the document size. When this is implemented, Step 4-4-6 is performed in the above implementation method.

5step 4-4-8 correction was performed uniformly regardless of the document size, so! It was not effective for originals smaller than lx, Qt7.

However, if the original size can be detected, corrections of 5 steps 4-4-6 and 5 steps 4-4-8 can be made according to the original size, and image formation by masking and trimming will be better than in the above embodiments.

The data corrected in step 5step 4-4 is stored in the RAM. By using the trimming/masking image forming method described below, masking/trimming of a plurality of areas separated by π or close together is possible.

FIG. 20 is a flowchart showing that area coordinates, color motes, and multiple motes can be input from the editor.

By pressing the key, the mode for changing the correction value of the editor input is entered.

Subsequently, by pressing the key (3) (press (3) on the numeric keypad 122 and press the asterisk key 121), the correction value input by the editor is changed to 3 mm. Also, if you press numeric keypad 122 times instead of (2) on numeric keypad 122, the correction value of the editor input will be
This means that it has been changed to mm. This means that no correction of editor input is performed. As mentioned above, correction of editor input is performed according to the flowchart (7) Step 4-4-1, 4-4-3.4- of FIG.
This means that the value of 5 mm shown in 4-5.4-4-7 has been changed.

Explanation of area specification using keys〉 Next, section 6 explains area specification using keys and inputting coordinates.
This will be explained using FIG. 4 and FIG. 65. An area memory (not shown) stores in advance three rectangular areas represented by two points located on the diagonal of the area. Note that the data may be lost even when used for the first time. Therefore, when performing area specified copying, the user selects which of the three areas to make valid.

Note that the combinations of areas that can be selected are Area 1 only, Area 1 and Area 2. There are three areas, areas 1, 2 and 3. This section explains how to specify an area. First, area key 128
When is pressed once, LED 138-1 (Fig. 64) lights up, and in this state 7u- only area 1 becomes valid. When area key 128 is pressed twice 1-1, LED 138-1 and 1
38-2 lights up 11 people, and in this state area 1 and area 2
or become valid. 3 times [Press I to display LE0138-1.1
38-2.138-3 lights up, and in this state area 1,
2.3 becomes effective. When you press it for the fourth time, all lights on LE0138 go out and the area designation is canceled.

As mentioned above, four pieces of coordinate data are stored in each of the three areas, and a case in which these data are changed will be described.

First, press area key 12 to specify the area you want to change.
Press 8. Area 1 each time you press the 1st, 2nd, and 3rd time.
．． Area 2. Area 3 is selected and, as shown in FIG. 65, a base pointer BP indicating the data to be changed is specified.

Note that the display on the LED 138 at this time is the same as in the case of specifying the effective area described above.

After specifying the area to be changed, by pressing the point key 104, the coordinates to be changed can be selected. First, when the point key 104 is pressed, the LED 139-1 blinks, the base pointer is designated as xl, and the coordinates of XI can be input. At this time, the currently stored
The data of I is displayed on the magnification display section 154. Furthermore, XI
is the X coordinate of the lower left corner of the area.

x2 is the X coordinate of the upper right corner, Yl is the X coordinate of the lower left corner, and Y2 is the X coordinate of the upper right corner.

When changing the xl data, it can be done using the numeric keypad 122 or the zoom magnification key 109. Note that when changing the value using the zoom magnification key 109, the 1 display section 15
Increase or decrease the value displayed in 4.

Then, when the point key 104 is pressed, the magnification display section 15
The data displayed at 4 is stored as xl data, and the currently stored x2 data is displayed on the display section 154, and the base pointer moves to x2. Furthermore, LED139-1 changes from blinking to lighting, and x2 LE
D139-2 blinks. Then, when it is necessary to change the data of x2, the same operation as above is performed. Thereafter, data can be changed in the order of Yl and Y2 by pressing the point key 104 in the same manner. Press point key 109 and Y2
When the data is memorized, the four LEDs X1 to Y2
139-1 to 139-4 go out.

Note that when the base pointer is not selected, that is, when the LE
When all of D13B-1 to 13B-3 are off, the data of X1 to Y2 cannot be changed even if the point key 104 is pressed.

Furthermore, when the point key 104 is pressed, the LED 13B of the selected area flashes, allowing the user to confirm the value of the base pointer. When the storage up to Y2 data is completed, the LED 138 of the selected area will be displayed.
changes from blinking to lighting, but the base pointer does not change unless the area key 128 is pressed.

Also, if you press the area key 128 while the XI-Y2 (7) LED 139 (7) is blinking or lit, the base pointer will move to the next area, but the base pointer is not specified in area 3. In this case, the data change mode is canceled.

Explanation of Blank Exposure> Next, the control of the LED array 14 during area designated copying will be described.

FIG. 22 shows a portion of the RAM, in which an area necessary for control is secured. In order to simplify the explanation, the number of areas that can be specified is set to two here. 200-5 stores the data of the area set by the operation unit 100 or the editor 70; 200-1 is the start data in the X direction (optical system scanning direction) of area 0;
0-2 is the end data of area 0 in the X direction, 200-3 is the start position data of area O in the Y direction (vertical direction), 200
-4 is the Y direction end data of area 0. Four pieces of data are set for one area, and area 1
The same applies to 200-6 is 200-3.

This is 0N10FF data of the LED corresponding to the data of 200-4, and in this embodiment, 5×24 bits are provided, and 1 bit corresponds to one LED.

For example, 100°200-4 to 200-3 (YOE)
When (YOE) is set to 200, the LED array 14 has LEDs arranged at a pitch of 2.5 mm, so 200-6 is 100/2.5 = 200/2 from the 40th bit. .5=bits up to the 80th bit are set to 1, and all other bits are set to O.

Similarly, data corresponding to the Y direction data of area 1 is set in 200-7. 200-8 is an area used when changing the lighting state of the LED array; 200-6.
The same number of bits as 200-7 are provided. 200-
Reference numeral 9 is an area where the LED array is actually set to be turned on dynamically.As will be described later, the data in this area is output corresponding to each digit, and the transistor group 8
Drive 2. 200-10 and 200-11 are output data switching flags used when changing the lighting state of the LED array.

This is an output current switching flag. 200-12 is a digit counter used to control which digit is output.

FIG. 23 shows how the LED array 14 corresponds to the area.
・When copying starts, the optical system starts scanning in the X direction. 201-1 determines whether it is an intra-area copy, and if it is an intra-area copy, 201-
Proceed to step 2 and set all LED output data 200-9 to l. As a result, all the LED arrays 14 are turned on and one image is completely erased. If it is not an intra-area copy, the process goes to 201-3 and all O's are set in the LED output data 200-9. This allows the LED array 14
will be turned off, and an image will appear in all areas in the Y direction. Then, in step 201-4, it is determined whether it is the start timing in the X direction of area O or not.

If so, the process proceeds to 201-12, and it is determined whether the end timing of area 1 in the X direction is reached. N.

If so, the process advances to 201-18 and similarly determines whether it is the start timing in the X direction of area 1. If no, 2
At 01-20, it is determined whether or not it is the end timing of area 1 in the X direction. If NO, the process advances to 201-22 and it is determined whether it is the optical system reversal timing. If NO, 201-4
Proceed to. In this way, if the timing to process is not reached, 201-4 → 201-12 → 201-18 → 201-
The loop of 20→201-22→201-4 is repeated in order.

Here, when the start timing in the X direction of area O is reached, the process proceeds from 201-4 to 201-5 and a series of processes is performed.

In 201-5, it is determined whether the start timing in the direction of area O is within area l, and the process proceeds to 201-6. In this case, since area 0 and area 1 overlap, the LED output buffer 200-8 is Set the logical sum of area 0 LED data 200-6 and area 0 LED data 200-7, and proceed to 201-8. On the other hand, if NO in 201-5, the start position of area O in the X direction does not overlap with area l. It turns out. Therefore, the LED output buffer 200-8 contains LED data 200-6 of area O.
Set the contents as is. Then, proceed to 201-8. In 201-8, it is determined whether or not the copy is within the area, and if it is the copy within the area, the process advances to 201-9.

At 201-9, the contents of the LED output bar 200-8 are inverted, and at 201-10, the output current switching flag 200-1 is inverted.
Set 1 and return to 201-4. Due to this,
For example, in the above example < 200-3. 10 to 200-4
If 0,200 is set, the LED at the position in the Y direction corresponding to 100 to 200 will turn off, and the other LEDs will turn off.
will now be turned on, and images will be output only inside the predetermined area. In addition, as will be described later, since only the output 'low flow switching flag 200-11 is set, when the previous LED array 14 is lit, digits 0 to 1 of digit 4 are set.
After the period of strong lighting, the lighting state of the LED array 14 is switched. On the other hand, if it is determined in 201-8 that it is not an intra-area copy, the process advances to 201-11, where both the output data switching flag 200-10 and the output current switching flag 200-11 are set. The LED output buffer is not inverted, so if <200-3°200
If Zoo and 200 are set to -4, only the LEDs in the portion corresponding to lOO to 200 in the Y direction are lit, and the image in that portion is erased. In addition, the output data switching flag 200-10 and the output data switching flag 200-1
Since both flags 1 are set, the lighting state of the LED array 14 is switched from the next digit O timing as described later, and the LED array 14 is turned on strongly for one period. Then, return to 201-4.

Next, a case where the end timing of area O in the X direction is reached will be explained. The process proceeds from 201-12 to 201-13, and it is determined whether the end timing of area O in the X direction is between the start position and end position of area I. If YES, the process advances to 201-14, and although the copying of area 0 has been completed, the end position of area O in the X direction is included in area l, so the area ILED is stored in the LED output buffer 200-8. Set data 200-7.

On the other hand, if No in 201-13, the process advances to 201-15, and since the end position of area O in the X direction is not included in any area, all 0s are set in the LED output puffer 200-8. Next, in 201-16, it is determined whether it is a medium copy or not, and if it is a medium copy, the process goes to 201-17 and the LED is displayed as before.
Invert the contents of output buffer 200-8. And 2
The output data switching flag 200-1'0 and the output current switching flag 200-11 are set at 01-11, and the output data switching flag 200-1'0 is set at 201-11.
Return to 4. On the other hand, if 201-16 is No, 201-1
0, only the output current switching flag is set, and 20
Return to 1-4.

Next, when the start timing of area l in the X direction comes, 2
The process advances from 01-18 to 201-19, and in 201-19, the same process as in the case of the start timing in the X direction of area O described above is performed.

This is a process in which the area numbers O and 1 are changed, and the explanation will be omitted.

Also, if it is the end timing in the direction of area l, 2
The process advances from 01-20 to 201-21, and here processing is performed with the area numbers 0 and 1 different from the above-described case of the end timing in the X direction of area O. When the timing of reversal comes as the optical system scans, the transition from 201-22 to 201-
Proceed to step 23 and input all the LED output data 200-9.
Then, all the LED arrays 14 are turned on and unnecessary images are erased.
Also, the optical system begins to move backward and one cycle ends. The same applies when there are three or more areas.

Next, the portion that controls the dynamic lighting of the LED array 14 will be explained with reference to FIG.

This routine is executed by a timer interrupt every 1m5ec.

First, the operation when both the output current switching flag 200-11 and the output data switching flag 200-10 are not set will be described. In this embodiment, the digits are from O to 4, and the digit counter 200=12 is updated at 202-1.
2 is also updated with a value from O to 4. If it is not O, the process goes to 202-11, and if it is 0, the process goes to 202-3 to turn off the strong lighting. 202-4 → 202-8 → 202-11
Then, the digit output and segment output corresponding to the digit counter 200-12 are set. For example, digit counter 200-12 is 1, 0
2 to 4 "Turn on the input O, and then press 7.7~" F, KO,: Output the contents of the data 200-13 that adds 15 to 0 of the LED output data 200-9. do. If it is ■, the corresponding LED is turned on, and if it is O, the corresponding LED is turned off. And it ends. The digit counter is updated sequentially, and the next timing is 20.
The digit 1 is turned on at 2-11, and the contents of 200-14 corresponding to the digit hl of the LED output data 200-9 are output to the segment output.

Next, a case where both the output current switching flag 200-11 and the output data switching flag 200-10 are set will be described. The content of digit counter 200-12 is O
The same process as above is performed until 0, and when it becomes 0, 2
Proceed from 02-2 to 202-3 and turn off the strong lighting. At this time, the state of the city is also that the strong lighting is off, so there is no meaning here.

Next, 202-4 → 202-5, turn on the 1 strong light,
Reset the output laminar flow switching flag 200-Lt.

Next, change from 202-6 to 202-9, reset the output data switching flag 200-10, and go to L at 202-10.
The contents of the ED output puffer 200-8 are set in the LED output gator 200-9. Then, the process of 202-11 is performed and the process ends. Then, digit counter 200
When -12 becomes O, it becomes 202-2-202-3, and the strong lighting is turned off, and since both flags have already been reset, the flow changes from 202-4 to 202-8 to 202-11, and normal processing is performed. Therefore, at the timing of digit O, LE
The D array output state changes, and the strong lighting is turned on for one cycle thereafter.

Next, the operation when only the output current switching flag 200-11 is set will be explained.

200 when digit counter 200-12 becomes O
-2 → 202-3 and turns off the strong lighting. 202-4
→202-5 and performs the same processing as described above. This time it changes from 202-6 to 202-7 and output data switching flag 2
02-11 is set, and the process ends after passing through 202-11.

Next, when the digital counter 202-12 reaches O, the sequence changes from 202-2 to 202-3, and the strong lighting is turned off. 20
2-4 → 202-8 → 202-9, the output data switching flag 200-10 is reset, and at 202-10, the LED output data 200-9 is changed to LED output 8 to 20.
The contents of 0-8 are set, and the output state of the LED array 14 is switched. Therefore, in the output state of the LED array 14 one cycle before, lighting is turned on for a little more than one cycle from digit O, and then the output state of the LED array 14 becomes K, which is updated. The timing of changing the digit output, high current, and LED output data is shown in FIG. 25. In FIG. -11, output data switching flag, the contents of the LED output buffer 200-9 are set depending on the image conversion mode.

Strong lighting occurs at the subsequent first digit 0 output timing t
It turns on at 2 and then turns off after one cycle T. On the other hand, LE
D output data is changed at timing t2 or t3 depending on the image conversion mode and whether the area starts or ends. The time t2 is used to change the area end timing for intra-area copying and the area start timing for out-of-area copying. Furthermore, the changes made at t3 are the area end timing for out-of-area copying and the area start timing for intra-area copying. As a result, as shown in FIG. 26, strong lighting is turned on on the non-image area side at the boundary between the image area 204-2 and the non-image area 204-1 in either the intra-area copy mode or the outer-area copy mode. As a result, sharp edges are maintained. Furthermore, by changing the lighting state of the LED in synchronization with the timing of digit O, the edge becomes more linear. The situation is shown in FIG. 27.

In Figure 27, 205-1 is LE with digit 2, for example.
This shows the case where the lighting of D is switched from all off to all on. In this embodiment, d is the distance that the drum travels in 1 m5ec, but as shown in Figure 1, a maximum deviation of 4d will occur. However, as in the present invention, the digit O
Since the deviation is always d as shown in 205-2, the boundary portion appears smooth. Also LED
Further linearity can be achieved by mounting the array at an angle.

"fS Figure 28 shows the output results when there are two areas in intra-area copy mode, and the shaded area is i6 cold h (medium h
■Since it takes the logical sum of the two areas, even if the two areas are far apart, the
<-Even if the image is wrapped, it is possible to obtain an image of only the desired portion.

FIG. 29 is a diagram showing the output result when there are two areas in the out-of-area copy mode, and 1,112 copies are the parts where 11 glimpses appear. As with intra-area copying, a desired portion of the image can be erased even if the areas are far apart or overlap.

Description of Editor ■> Next, different embodiments of area specification will be described. FIG. 30 shows the editor 250-1.

250-2 is the image conversion mode setting part, 250-
3 is a part for specifying an area.

In the mode setting part, fill specification of 250-4, 2
There are 50-5 color specification within the area, 250-6 color specification outside the area, 250-7 intra-area point specification, 250-8 specification of disease outside the area, and 21ji specification for the area specification 250-3. By pressing the mode setting area after pressing the button, the area (a rectangle with two diagonal lines) is set and the mode of that area is registered.

The filling designation 250-4 is for filling the set area in color regardless of the state of the document. 25
0-5 color specification within the area outputs an image with color toner only inside the set area, and 250-6 color specification outside the area outputs an image in color only outside the set area. be. 250-7's intra-area point specification outputs an image in black only inside the set area, and
The color outside the area 50-8 outputs an image in black only outside the set area.

Fig. 31 shows an area data area 251-7 provided in the RAM for storing specified area data. , outer black, etc., and parts 251-2 to 251-5 to store coordinates of designated areas. In the region data area 251-7, a plurality of pieces of data 251-6 regarding one area designation are set. When two points on the area designation part 250-3 are pressed and then the mote designation part of 250-2 is pressed, the mode changes to 251-1.
Additionally, point data is stored in 251-2 to 251-5.

The 32nd copy operation after the next copy command is input is
This will be explained according to the diagram. First, in step 252-1, all locations where the mode of area data area 251-6 is stored are searched and investigated. At step 252-2, it is determined whether a black fill mode or a red fill mode is set therein. First, the case where it is set will be explained.

252-3 feeds the transfer paper from the cassette, and performs a copying operation that fills in only the portion corresponding to the specified fill area with the specified color, as described later.The transfer paper is placed with the copied side facing down. When the transfer paper is set in the second paper feed section 23, the transfer paper is placed in the designated 255-
Only part 2 is filled with color, and the other parts are white. At step 252-4, it is determined whether there is a designation of the color within the area or the color mode outside the area, and if no, the function 252
-Go to 7. If YES, it is determined at 252-5 whether the mode of black inside the area or black outside the area is specified, and if NO, the process proceeds to 252-7, and if YES, the process proceeds to 252-6. Therefore, when making both color and black copies, 252-
The process advances to 6, and if one color is to be copied, the process advances to 252-7. 252-6 feeds paper from the second paper feed section, performs color copying in the area specification mode to the specified area as described above, and transfers the transfer paper to iQ and the second paper feed section with the dented side facing down. is set. Next 252
At -8, paper is fed from the second paper feed section, black copy is made in the area specification mode to the designated area, the transfer paper is discharged outside the machine, and the copying operation is completed.

Therefore, in this case, as shown in FIG. 35, a fill-in copy is first made, then a red copy is made on the same side, and finally a black copy is made on the same side, and the process is completed.

On the other hand, if the process advances to 252-7, paper is fed from the second paper feed section 23, a copying operation is performed according to the designated color and area, and the transfer paper is discharged outside the machine, and the process ends.

Next, the case where no fill mode is specified will be explained. The process proceeds from 252-2 to 252-9, and in 252-9 it is determined whether there is an inside color mode or an outside color mode. If NO, proceed to 252-12; if YES, proceed to 252-10. At step 252-10, it is determined whether or not the mode of black inside the area or black outside the area is set. If you need to do it, go to 252-11 2 If you only need one side, go to 252
Proceed to -12, feed paper from the cassette at 252-11,
Copy the specified area in color, and
Load the paper into the paper feed section 23 with the copied side facing down. Next, at 252-8, the paper is fed from the second paper feed section as described above, a black copy is made, and the paper is ejected outside the machine, and the process ends. On the other hand 252-12
If the process advances to , paper is fed from the cassette, copying is performed according to the specified color and area, and the transfer paper is ejected to the outside of the machine and the process ends.

Next, fill-in copy will be explained.

When filling in the image, by leaving the exposure lamp 24 off, an electrostatic latent image of a solid image is formed on the photosensitive drum 20. Therefore, as explained above regarding area copying, by selectively lighting up the LED array 14 at the timing according to the designated area, it is possible to erase the latent image of the unnecessary part and output only the desired part as a solid image. I can do it. FIG. 33 shows the flow.

At step 253-1, the I and ED arrays 14 are all turned on, and thereafter, feeding of the transfer paper is started at a predetermined timing.

Next, it is determined at 253-2 whether or not it is the area start timing, and if NO, the loop is repeated at 253-2. Thereafter, when the area start timing comes, the LED array 14 is selectively turned on in accordance with the Y-direction coordinates of the designated area at 253-3.

i4. :253-4, it is determined whether the end timing of the area in the X direction has come. When the end timing of the area in the X direction is reached, the LED array 14 is completely turned on in step 253-5, and the image is erased over the entire area. Then, it is determined by counting pulses at 253-6 whether or not the development for the size of the transfer paper has been completed, and if YES, one cycle is completed.

Next, an example of the copy result is shown in FIG.

In the diagram, 254-4 is filled in with color,
254-3 is copied in black, this is 254-4
The image inside is similar, and as shown in the figure, black characters "ABC'" (corresponding to the original) are output on the area 254-4 filled in color. 254-
In 2, the original is copied in color, and in the other parts, the image has been deleted. The operation when such a copy result is desired is as follows. Manuscript editor 250-1
, and input two points on the diagonal line of the area 254-4 using the editor. Next, specify the fill mode of 250-4. Press two points on the diagonal line of the area 254-3, and then press the area color designation part 250-5. 25
Press the two diagonal points in the area 4-2. Finally 250-7
Press the area black and white designation area. Then, place the original on the document table and press the copy key. By these input operations, first 25
The filled part of the area 4-4 is copied, then the part 254-2 is copied in color on the same side, and finally the 254-2 area is copied in color.
The portion 54-3 is copied in black, and the copying ends automatically. This can be done with very simple operations. Furthermore, since the filled-in copy is performed first, the document can be copied over the filled-in area, and a good copy can be obtained when, for example, a title section is to be made more noticeable. In addition, you can input the color part, black part, and fill-in part at the same time, which makes the operation very easy and eliminates the need to set the document on the editor or document table many times. Moreover, it is consistent with human thinking.

Furthermore, by using a narrow LED during irradiation, it is also possible to draw a thin line such as an underline.

In the example of the output result shown in Fig. 34, there is only one area in each of the color within area, black and white area, and fill mode, but it goes without saying that multiple areas are possible as explained above. be. Further, although only the mode shown in FIG. 30 is registered for one area, it is also possible to add, for example, copy magnification and position specification of where on the transfer paper the image of the area should be displayed.

The copy magnification and position designation are added to the section 251-1 shown in FIG. 31 where the mode is recorded.

During a copy operation, for example, two areas with color inside are registered, and one of them is 100% (area L).
If the other one is set to 64% (area 2), 252-6 or 25% in the flowchart shown in FIG.
The operation of step 2-11 can be done as follows, 10
A color copy is made of only area l at a copying magnification of 0%, and the transfer paper is set in the second paper feed section 23.

Next, change the magnification and set the copy magnification of 64% to the second paper feed section 23.
Paper is fed from , color copy is made only in area 2,
Then, the transfer paper is set in the second paper feed section 23. Further, it is possible to specify the position by calculating the difference between the position specification value and the area for each order, and shifting the transfer timing of the transfer paper by the difference (only in the X direction in this embodiment). Similarly, when a position is specified, for example, if there is a deviation of -1 in the feeding timing of the transfer paper due to the position specification of a certain area, and the deviation calendar of another area is different, multiple copying may be performed in two exposures.

Furthermore, if multiple copies are made on a single sheet of transfer paper many times, the transfer paper will be damaged, leading to poor conveyance and paper jams, or poor transfer performance, making it impossible to obtain good images. Therefore, each time an area is registered, the number of times that multiple copies must be made is calculated, and if it is less than a predetermined value, the registration is prohibited and a warning is displayed.

In the above embodiments, the images of each designated area are multiple-copied onto the same transfer paper, but each area may be copied onto separate transfer paper. In addition, in such a mode, it is impossible for the image in the designated area to appear at the leading edge or center of the transfer paper. trouble key 12
1, press (2) on the numeric keypad 122, and press the trouble key 12.
By pressing 1, it is possible to specify that the designated areas be copied onto separate transfer sheets.

Furthermore, by pressing the trouble key 121, pressing (2) on the numeric keypad 122, and pressing the trouble key 121, it is possible to specify that the image should be aligned with the leading edge of the transfer paper.

Furthermore, by pressing the numeric key 121, pressing (4) on the numeric keypad 122, and then pressing the numeric key 121, it is possible to specify that one image be placed in the center of the transfer paper.

At the start of the copying operation, first, copying is performed according to the mode and coordinates set at the beginning of the area data area shown in FIG. 31, and then the transfer paper is discharged outside the machine. If the mode set at the beginning is in trouble, the transfer paper feed timing is delayed by XO. If the mode set at the beginning is difficult, the next calculation is performed.

However, the intersection is the transfer paper size.As a result, if the value of T is positive, the transfer timing of the transfer paper is delayed by T. On the other hand, if the value of T is negative, the transfer timing of the transfer paper is increased by ITI by 11'-.

Next, referring to the second area designation of the area data area in FIG. 31, if it is registered, it is similarly copied and ejected from the machine.

Then, the copying is performed sequentially, and all areas registered in the area data area of FIG. 31 are copied, and the copying operation of -il is completed.

According to the present invention, as shown in [I] above, 5. For example, a newspaper entry, 11.
If you file by item [I, you can specify multiple newspaper entries at once. It is also possible to copy onto separate transfer sheets with a single copy command. Furthermore, it is very convenient because the recording bar can be copied to the position ψ on the transfer paper.

Figure 35-1 shows the output result when two areas are specified to appear in the center of separate transfer sheets.
35-12 and 35-13 are designated for the original, and the portion 35-12 is copied onto the center portion 35-15 of the transfer paper 35-14. Also, a portion 35-13 is copied onto the center 1 portion 35-17 of the transfer paper 35-16.

Description of Copy Paper Conveyance Path> As described above, this embodiment has two systems of copy paper refeeding mechanisms for realizing double-sided copying or multiple copying. That is, the second paper feed section 23 and the intermediate tray 40
It is. Which of these is used depends on the copy mode.

That is, the copy program determines the optimal system based on the size of the copy paper and the set number of copies. The former is a paper refeed unit that is essential for realizing double-sided and multiple copying.
Since horizontal registration is easy with the mechanism described later, there is a degree of freedom in paper size. However, you cannot store more than one sheet of paper there. On the other hand, the latter allows multiple sheets of paper to be stacked, but horizontal alignment can only be done to a predetermined fixed size.

Part 63: How to choose a paper path for double-sided/multiple copying
This will be explained according to the diagram.

When a copy operation is started by a copy command, first 270
-1, it is determined whether double-sided/multiple copying is to be performed on the same original, that is, without exchanging originals. For example, in the case of a mode in which a predetermined portion of a document is copied in color and other portions are copied in black, the answer is YES. If YES, 270-2
to determine whether the original is a standard size. If it is not a standard size, the process advances to 270-5 and the second paper feed section 23 is unconditionally loaded.
Select. If YES, the process advances to 270-4, where it is determined whether the set number of copies is one, and if YES, the process similarly advances to 270-5. If No, it is determined in 270-4 whether the number of copies 1 is larger than 30 sheets, which is the maximum number of sheets that can be loaded on the intermediate tray 40, and if YES, the process proceeds to 270-5, and N
If o, proceed to 270-8.

270-5 copies one sheet and transfers the transfer paper to the second paper feed section 23.
The transfer paper is set in the printer, the paper is re-fed from the second paper feed section 23 at 270-6, the copy is made, and the transfer paper is discharged to the outside of the machine.

270-7 determines whether the set number of copies have been completed, and if No, 270-5 → 270-6 → 270
-7 loop is repeated, and the copying operation continues until the set number of copies is completed, and then ends. On the other hand, if the process advances to 270-8, the intermediate tray 40 is used to perform a copying operation. 270-8 copies the set number of sheets and sets the transfer paper on the intermediate tray 40. Next, in step 270-9, the paper is re-fed from the intermediate tray 40, copies are made for the set number of sheets, and the process is finished.

If the determination is No at 270-1, the process proceeds to 270-10. 270-1o determines whether the original is a standard size, and
If O, the copy setting number is set to 1 at 270-17, and the process proceeds to 270-18. If YES, determine whether the set number of copies is 1 at 270-11; if YES, 27
The process advances to step 0-18 and the second paper feed section 23 is selected.

If NO, select the intermediate tray 40.

The number of copies is determined at 270-12, and if it is 30 or more, 30 is set as the set number of copies at 270-13.

Next, at 270-14, the set number of copies are made in the same manner as at 270-8, and the copies are set on the intermediate tray.

When the original is replaced at 270-15 and a copy command is output, copying is performed at 270-16 in the same manner as at 270-9, and the process ends. On the other hand, when the second paper feed section 23 is selected, the second paper feed section 23 is selected.
Copy 70-18 in the same way as 270-5, and 270-1
When the original is exchanged at 9 and a copy command is output, 270
At -20, copy in the same way as 270-6 and end.

As explained above, in this embodiment, multiplex/double-sided copying, temporary copying, and copying of sizes other than standard sizes are performed.

When feeding paper from the instant tray, universal cassette or manual feed tray, and for single-sheet copying, the paper is placed in the intermediate tray 40.
The sheets are sent directly to the second sheet feeding section 23 for re-feeding without being sent to the second sheet feeding section 23. When copying a large number of regular sheets, the sheets are once stacked on the intermediate tray 40 and then sent to the second sheet feeding section 23 for re-feeding.

The choice of which of the two types of systems to use is not made by the operator, but is done automatically by the sequence program, so the operator does not have to think about it each time, and control is always performed using the optimal system. . In addition, for non-standard multiple copies, it is possible to perform copying one sheet at a time using the second paper feed without using an intermediate tray. Furthermore, unnecessary troubles can be avoided by determining the inconvenience of the transfer paper (such as the size being too small) and discharging it outside the machine without performing double-sided/multi-hair copy processing.

The copying apparatus of this embodiment can also be equipped with an automatic document feeder (hereinafter referred to as ADF), and the ADF is shown in FIG. Various proposals have been made in the past, and here we will explain the operation inside the cylinder. In FIG. 61, 260-12 is an ADF that can set a plurality of originals and automatically feeds them, 260-11 is an original tray for setting originals, 260-10 is an original sensor that detects originals, 260 -1 is a paper feeding auxiliary roller for feeding the original, 260-2 is an upper belt, 260-3 is a lower belt, 260-5 is a paper feeding roller, and 260-6 is a driving roller.

260-7 is a conveyor belt driven by 260-6;
260-8 is a paper discharge roller, and 260-9 is a paper discharge tray section.

When a document is set on the document tray 260-11, the document sensor 260-10 detects the document. A motor (not shown) rotates in response to the copy command, and each drive unit starts operating. The paper feed auxiliary roller 260-1 moves in the direction of arrow A by a mechanism not shown, and conveys one document to the paper feed roller 260-5.
-Have sex. Thereafter, the document is conveyed by the feed roller 260-5 and the conveyance bell I. When the leading edge of the document reaches the reference position of the document table 5 shown in FIG. 1, the document is stopped 1-.

Exposure of the original is started by moving the optical system, and when the exposure of a predetermined number of originals is completed, the ADF starts operating again. At this time, if the document sensor 260-10 detects the document, it feeds the next document in the same way as described above, and at the same time, the ffXm set on the document table 5 passes through the paper ejection roller of 260-8. The paper is discharged to the paper discharge tray section 260-9. Then, the next original is copied. 260-11 with this action
Repeat until there are no originals left on the original tray. When the last original is set on the original platen 5 and the prescribed original exposure is completed, the original sensor of 260-10 does not detect the original at this time, so no paper feeding operation is performed and the original is placed in the output tray of 260-9. Eject and complete one series of copies.

FIG. 62 is a flowchart illustrating that copying operations differ depending on the number of ADF originals in double-sided or multiplex mode.

In Step 7-1), the original is set in a predetermined position. At that time, the document tray 260-1
The document sensor 260-10, which detects the presence or absence of a document at step 1, determines whether there is one document or a plurality of documents (Step 7-2).

First, we will discuss the case where there is only one manuscript.

If NO in step 7-2, it can be determined that there is only one original set. The operation of copying the first side is completed,
Convey the transfer paper to the second paper feed section 23 (Step 7-13
) - Then, the original is ejected (Step 7-14), and the transfer paper in the second paper feed section performs the copying operation for the second side according to the next copying operation start command, completing the copying operation of l. do.

Next, a case where there are multiple manuscripts will be described.

If Step 7-2 is Yes, it can be determined that there are a plurality of originals set. The copying operation for the first side is completed, and the transfer paper is conveyed to the second paper feeding section 23 (S
step7-3). Then, the original is ejected, and then the original on the original tray 260-11 is fed (Step 7-
4). The copying operation for the second side is performed and the transfer paper is discharged outside the machine (Step 7-5). and document tray 260-1
Determine whether there is a mistake in the manuscript in step 1. 5step 7 6)
, if there is no original, eject the original (5step 7-14)
, completes a series of (7) mbee operations.

Also, if there is a document in the document tray 260-11.

Eject the original and feed the next original (Step 7-7)
. Then, it is determined whether or not the next original is in the original tray 260-11 (5step 7-8), and if there is, the first side is copied and the transfer paper is conveyed to the second paper feeding section 23 (
Steps 7-9). Then, the original is ejected, the first original is fed, the second copy operation (1) is performed, and the transfer paper is ejected from the machine. Then, the process is executed again from step 5 step 7-6.

If No in step 7-8, after the copying operation for the first side is completed, the transfer paper is ejected from the machine (step 7-12), and the original is ejected (step 7-14), completing a series of copying operations.

As described above, differences in copying operations depending on the number of ADF originals have been described. Now, this effect includes the following.

For example, when combining large-sized originals such as newspapers that cannot be fed with an ADF and originals that can be fed with a regular ADF, or when performing duplex/multiple copying, when the number of originals set is one The ADF could not be used to obtain double-sided or multiple copies for ejection.

Furthermore, for the same reason as above, it was not possible to make double-sided copies of double-sided originals using the ADF.

Furthermore, when attempting to obtain multiple or double-sided copies of two originals by using masking and trimming copy modes, the area cannot be specified for the two originals at the same time. Therefore, the originals must be set one by one, but for the same reason as mentioned above, there is a serious drawback in that the desired copy cannot be made using the ADF.

According to the present invention, the above-mentioned drawbacks can be eliminated, and in the case of an odd number of originals in a series of multiple sheets, the last copy is ejected outside the machine, so that it can be used in the same manner as in the past.

After the processing in Step 7-13 and 7-14 described above, the transfer paper is in the second paper feeding section 23. A flowchart regarding subsequent processing is shown in FIG. 62-1.

When the reset key 119 is pressed (Step 7-15)
, the transfer paper in the second paper feed section 23 is conveyed through the second paper path and discharged outside the machine (Step 7-21).

When the copy key 117 is pressed (Step 7-16), A
If there is a document in the document tray 260-11 of the DF (St
e p7-17), feed the original 5tep7-18)
, performs a copying operation for the second side, and discharges the transfer paper to the outside of the machine (Step 7-19). Then, the original is ejected and the series of copying operations is completed (Step 7-20).

If there is no original in Step 7-17, it is determined that the original has been manually set, the second side is copied, and the transfer paper is ejected from the machine (Step 7-20) - and the series of copy operations is completed. .

Description of Sequence> Next, the sequence will be explained using FIGS. 36 to 60.

The operation when the power is turned on will be explained. FIG. 36 is a time chart when the '1 heat source is turned on. When the main SW is turned on, the fixing heater and black developer release solenoid are turned on. Eventually, when the fuser temperature reaches 190°C, the motor is rotated, and after 1 second (■), the black developer pressure solenoid is turned off. As a result, the black developer reaches the first generation release position, and then You will be approaching the tram.

After that, when the drum rotates once, the main motor is stopped. Also, if the middle plate of the cassette in the paper feed section is down when the motor starts rotating in 2), the middle plates of both the upper and lower cassettes start to be raised. This situation is shown in FIG. Then, after the middle plate has finished rising, stop the main motor (■
).

Figure 37 is a time chart for the rise of the middle plate, and is the same for both the upper and lower rows. When the middle plate rising clutch is turned on, the middle plate begins to rise. Eventually, the output of the middle plate detection sensor becomes 1, and after 0.1 seconds from this point, the middle plate lifting clutch is turned off. -Is the force paper detection sensor l-5'? As shown in the figure, if there is paper, find the position where the output of the paper detection sensor becomes 1 before the output of the middle plate detection sensor becomes 1. are in a relationship. Further, when the output of the middle plate detection sensor becomes 1, the paper detection sensor is determined, and if it is O, the paper out display is turned on.

Further, if no cassette is installed, this operation is not performed.

Next, the copy operation will be explained. When the copy key is pressed, the main motor, high voltage, and document illumination lamp are turned on. Also, the paper feeding operation and developing device pressurizing operation, which will be described later, are started. After one rotation of the drum, the optical system moves forward and turns on the registration roller tl after the image edge is detected. After that, it will turn off after a period of time depending on the paper size. After that, when the optical system comes to the inverted position, the optical system is moved backward a1. The original illumination lamp is turned off by 0.2 sand diameter. Stops the optical system when it returns to the home position]
-Starts rotation after breaking. It stops after the transfer paper is ejected outside the machine. In the case of color copying, a developer pressurizing operation, which will be described later, is performed.

Next, the pressurizing operation of the developing unit will be explained. FIG. 39 is a timing chart when color copying is started with the black developing device set. First, turn on the black developer release solenoid to release the black developer from the drum. After the release is completed, the color pressure solenoid is turned on and the color developing device is set on the drum. When copying is complete, turn off the color pressure solenoid and release the color developer. Incidentally, at this point, the black developing device remains disabled. In order to replenish color toner smoothly, this is always canceled when color copying is completed (11)
. When starting black or color copying from this state, both developing devices are already released. Further, after black copying, the black developing device remains set on the drum.

Next, the paper feeding operation will be explained. FIG. 40 shows a timing chart. If the output of the intermediate plate detection sensor is O at the time of copy start, the intermediate plate lifting operation is performed in the same manner as explained in FIG. 37. The paper feed clutch is turned on after the middle plate lifting operation is completed.
L. The transfer paper begins to move. Thereafter, when the transfer paper reaches the registration front paper sensor, the output of the registration front paper sensor becomes 1, and after a predetermined time, the paper feed clutch is turned off, and the transfer paper hits the registration rollers and stops in a loop state.

Thereafter, as the copying operation progresses, the paper feed clutch is turned on again for a predetermined period of time when the registration rollers are turned on, thereby reducing the paper feeding load on the registration rollers. On the other hand, the control of the middle plate is then performed asynchronously with the copy operation, and when the output of the middle plate detection sensor becomes O, the middle plate lifting clutch is turned ON.
, and after the output of the middle plate detection sensor becomes 1, it becomes 0.1.
Turns off after seconds.

Also, the presence or absence of the cassette is constantly detected, and if the cassette begins to come out, the operation of lifting the middle plate is immediately stopped.

Next, the paper feeding operation in the case of pointer copying will be explained.

At the same time as copying starts, turn on the manual feed tray J second clutch and start pushing the hair feed tray. '', the output of the paper detection sensor becomes 1 if transfer paper is set. After a predetermined time, the paper feed clutch is turned on, and 3 ( is fed into the machine. After the time t5 until the transfer paper is gripped by the next roller, the r-insertion tray I-shift clutch is turned off, and -5η and the tray descends, causing the paper detection sensor to appear. On the other hand, the transfer paper is sent to the pre-registration paper 4J-37, and is fed a predetermined time after the output of the registration riir sensor S7 becomes 1. The transfer paper hits the register roller, creates a loop, and stops.

Next, the copying of the first side of a double-sided copy of a single will be explained. High pressure, unit, wrap.

Since the movements of the optical system, paper feeding operation, etc. are the same as described above, the movement of the transfer paper after the registration roller 12 is turned on will be explained. FIG. 41 is a timing chart in which the transfer paper is sent to the fixing device by turning on the registration roller. After that, when the paper passes the paper discharge sensor, the output of the paper discharge sensor S4 changes from O→1→0. At this time, the lateral registration means, which will be described later, is moved to the home position. After a predetermined period of time, when the transfer paper is gripped by the discharge roller 27 at a position approximately LO mm from the trailing edge, the reverse solenoid is turned on to switch pack the transfer paper. At this time, the second transport latch is also turned on. The transfer paper is sent to the second conveyance section 23, and the second pre-registration sensor S
The output of 5 becomes 1. After a predetermined period of time, the second conveying latch is turned off, and the sheet rolls: the paper hits the second registration roller, creates a loop of about 15 mm, and then stops. At this time, the reverse solenoid is also turned off. Moreover, the second conveyance section 2
3 can only feed transfer paper with a length of about 180 mm or more. For manual copying where the transfer paper size is unknown, cross from registration roller 12 on = 180-24 (24
Determine the human power of the registration front paper sensor S7 after a distance of mm (distance between the registration front paper sensor and the registration roller),
If there is no paper, the size of the transfer paper is less than 180 mm, so the transfer paper is ejected from the machine without entering the switch/drop operation. On the other hand, if there is paper, a predetermined operation is performed because the size of the transfer paper is 180 nm or more.

Next, I will explain the first side of the single copy.

The movement of the transfer paper after the registration roller is turned on will be explained. Fourth
Figure 2 is a timing chart showing this. Along with the registration roller ON, the flapper solenoid 29 is turned on, and the later-described lateral registration means (second registration roller 37
) to the home position. After the transfer paper has moved by a distance, the pre-registration sensor is checked in the case of manual copying, as in the case of double-sided copying described above. If paper is not detected, turn off the flapper solenoid 29 and let it out of the machine. Transfer paper advances and paper ejection sensor S4
When the output becomes 1, the second transport latch is turned on.

The second transport latch is turned off after a predetermined time t4 after the transfer paper is transported to the second +ti transport section 23 and the output of the second pre-registration sensor becomes 1. The transfer paper is the second registration roller 37
When it hits 7fi, it creates a loop and stops.

In the case of double-sided copying described above, the curl condition of the transfer paper
E. Since the direction is different, the time t4 from when the output of the second pre-registration sensor 55 becomes 1 until it stops at 1- changes its value.

Next, the copying operation for both sides of a single and the second side of multi-copying will be explained based on FIG. 44. The transfer paper is already in the second conveyance section and hits the second registration roller 37, forming a loop and stopping! I'm watching. When copying starts, the second registration roller clutch and double-sided conveyance latch are turned on, and the transfer paper begins to move toward the second registration roller 12. O, 1 second later, place the second part 17mm from the tip of the transfer paper.
While it is held on top of the registration roller, start the ilJl movement (later-described lateral registration). Regime) +pj
After the sensor output becomes 1 and time Tb elapses, the second registration roller clutch and double-sided conveyance latch are turned off. The transfer paper hits the registration roller, creates a loop, and stops F.

After that, the optical system starts moving forward, and it is time to turn on the register rollers. After the transfer paper has been fed by about 5 mm, in the case of one-sided copying, the second registration roller clutch and the duplex transport latch are turned on, and the transfer paper advances with the loop reduced by 5 mm. On the other hand, in the case of multi-hair copying, only the duplex transport latch is turned on, and the transfer paper is moved to the register roller 12.
As a result, the second register roller 37 becomes a load, and the transfer paper continues to be conveyed in the loop state. Thereafter, the transfer paper passes through a fixing roller and is ejected from the machine, completing the copying process. Further, the time tb for determining the loop state before registration is set differently from that in the case of paper feeding from a cassette because the transfer paper conditions are different.

Next, the operation of setting the second registration roller to the lateral home position will be explained. The drive of the main motor is transmitted to the second registration roller via a spring clutch.
By turning on the lateral registration solenoid, it is possible to move in the lateral direction. A lateral registration home sensor for detecting the position of the second registration roller and a lateral registration paper sensor for detecting the transfer paper held therebetween are arranged. The second registration roller moves in both directions with respect to the axial direction of the tram, but in order to improve the accuracy of the stop F,
Be sure to stop the movement from one direction. That is, as shown in the timing chart of FIG. 45, if the output of the lateral registration home sensor is 1 at first, it is stopped when it changes from 1 to 0 to 1, and if it is 0 at first, it is stopped when it changes from 0 to 1. Stop I: Allow.

Next, the lateral registration adjustment operation will be described. In FIG. 47, 37 is the second registration roller.

S8 is a horizontal registration paper detection sensor, and SH is a transfer paper. When the second registration roller 37 is set at the home position, it is stopped at the center point of its operating range, and by turning on the horizontal registration solenoid, the arrow (K) shown in Fig. 1 is turned on.
)→(S→・■→〈It moves as shown in p. When the second registration roller 37 stops at the home position (depressed state) and inserts the transfer paper, depending on the position of the transfer paper, the first , the horizontal registration paper sensor may or may not be detecting paper. First, we will explain the case where paper is being detected. As shown in FIG. 46, the output of the horizontal registration paper sensor changes from 1 to O+1. In addition, if the transfer paper comes in extremely biased towards the side of the horizontal registration paper sensor, there is a risk that the output of the horizontal registration paper sensor will always be 1. In order to stop at the +h position, the following is done.That is, as shown in Fig. 47, when the arrow ■ moves to the middle of the arrow, the transfer paper is furthest away, and at this point the horizontal registration paper If the output of the sensor is 1, it will move in the direction of the arrow (■), so the output of the horizontal registration paper sensor will never become 0. Also, the most appropriate position is to stop F at that point. .Therefore, if the time of one cycle of the horizontal movement of the registration roller is T, then even if the registration roller is moved by a time corresponding to 3/4T, that is, the arrows ■ and l, the output of the horizontal registration paper sensor will be 0.
If it does not, it will stop there.

Next, we will first describe the case when the output of the horizontal registration paper sensor is O, that is, the transfer paper is cutting the horizontal registration paper sensor. At this time, as shown in FIG. 46 (11), when the output of the horizontal registration paper sensor changes from O to 1, it is stopped F. Furthermore, if the transfer paper comes in at an extremely distance from the lateral registration paper sensor, the output of the lateral registration paper sensor will remain at O. Even in that case, in order to stop at the appropriate position as much as possible,
If the output of the lateral registration paper sensor does not become 1 even after moving by 1/4T for 11ν corresponding to ■ in FIG. 46, it is stopped at that point.

Next, the operation of the first side opening for double-sided copying when an intermediate tray is used will be explained. After copying starts, paper feeding, high pressure,
Since the movement of the optical system is the same as described above, the movement of the transfer paper of the second registration roller will be explained. FIG. 48 is a timing chart in which the flapper solenoid and intermediate tray flapper are turned on at the same time as the registration roller is turned on. Second
The transfer paper sent out from the registration rollers passes through the fixing rollers and is conveyed directly to the intermediate tray. The intermediate tray entrance sensor can detect the number of transfer sheets stored in the intermediate tray, and after detecting the set number of sheets, the operation is stopped.

Next, the operation of the first-page copying machine when using the intermediate tray will be explained. FIG. 49 is a time chart showing that the intermediate tray flapper is turned on at the same time as the second registration row is turned on to form a paper path for conveying the transfer paper to the intermediate tray. The transfer paper is sent out from the registration rollers and when it passes the paper ejection sensor section, the reverse solenoid is turned on.
Similar to the above-mentioned double-sided copying of one sheet, the transfer paper is switch-packed and conveyed to be stored in the intermediate tray. that time,
The intermediate tray entrance sensor counts the number of sheets stored, and stops operation when the set number of sheets is detected.

Next, the operation of the two-sided opening for multiplex and double-sided copying using the intermediate tray will be explained. Transfer paper is already stocked in the intermediate tray, and the transfer paper is set from there to the second conveyance section 23. The situation is shown in FIG. First, turn on the intermediate tray paper feed roller lenoid. The paper feed roller 5b is lowered by a drive means (not shown), and the topmost transfer paper is abutted against the feed roller 57. Thereafter, the intermediate tray feeding roller lenoid is turned on, and the transfer paper is sent out to the conveyance path 59 by the intermediate tray feeding roller 57. When the leading edge of the transfer paper reaches the intermediate tray exit sensor 521, the intermediate tray paper feed roller runnoid is turned off, and the paper feed roller 56 is moved to the upper R.
1L, there is no contact with the transfer paper. At this time m2J
The fit feed latch is turned on, and again.

The above-described operation is started to set the second registration roller 37 to the home position.

The transfer paper eventually reaches the second pre-registration sensor S5, and after a predetermined period of time, the transfer paper hits the second registration roller and creates a loop, and then the second registration roller 37 is turned on, and the transfer paper moves to the second registration roller 12. sent towards.

The subsequent operations are the same as those for the second side of the single multiplex one-sided copy described above.

Next, the operation of replenishing the black developing device 8 with toner from the hopper will be described. In Fig. 51, 301 is a hopper, 3
02 is a screw that stirs the toner in the hopper 301 and sends it to the black developing device 8, and is driven by the hopper motor 300. Inside the black developing device 8, a toner sensor S16 for detecting the presence or absence of toner, a stirring rod 8-b for stirring the toner, and a developing sleeve 8-a are arranged. The stirring rod 8-b is driven by a main motor 18 (not shown),
Its period is 4 seconds. When the toner sensor 316 detects that there is no toner, the hopper motor 300 is rotated to replenish toner. Further, even if the hopper motor 300 is driven to a certain extent, if the toner sensor 516 does not detect toner on the right side, it is determined that there is no toner in a part of the hopper, and a display is displayed to notify the user. This control will be explained in detail.

The control method during copying and when copying is stopped is different, and when copying is stopped F, as shown in FIG. 52, if no toner is detected at that time, the hopper motor 300 is rotated for 10 seconds. On the other hand, if the presence of toner is detected at this time, nothing is done.

Next, the control of the hopper motor 300 during copying will be described. By rotating the stirring rod 8-b.

For example, if the stirring rod 8-b contacts the toner sensor 516 even though there is no toner, the toner sensor output may indicate that there is toner. This time is a maximum of 1 second. on the other hand.

Even though there is toner, the stirring rod removes toner particles near the toner sensor 516, so the toner sensor output may indicate no toner. The time during which it is detected that there is no toner is 2 seconds at most. Therefore, as shown in FIG. 53, when the toner no. 4g signal continues for more than 1 second, the hopper motor 300 is driven, and when the toner present signal continues for more than 2 seconds, it is determined that there is toner in the developing device, and the hopper motor 300 is activated. 300 and resets the hopper no-partner timer, which will be described later.

On the other hand, if there is no toner in the hopper, no matter how much the hopper motor 300 is rotated, the toner sensor 316 will not indicate the presence of toner. This detects the absence of toner in the hopper.

The time during which the hopper motor 300 is rotating is measured by a hopper partnerless timer, and when the total time reaches 18 seconds, it is determined that there is no toner in the hopper 300 and a display is performed. This timer is reset when the power is turned on and when the presence of toner is detected during copying.

Next, the operation of the blanking LED array 14 will be described. This LED array 14 not only prevents toner from adhering to unnecessary areas of the drum 20, but also allows you to create a white area of approximately 2 mm at the leading edge of the transfer paper, and to whiten the area inside or outside the area specified in the area specification mode. (Masking.

trimming). The control timing is taken from the signal from the image tip sensor S2 that detects the position of the optical system 24. A shielding plate 24-a (FIG. 55) is attached to the optical system 24.

When this blocks the image tip sensor S2, a signal is output. The length of the shielding plate 24-a is Q,2, and a signal is output as shown in FIG. 56 when the optical system moves forward.

In FIG. 56, the rising edge of the image sensor output is defined as a blur image edge signal, and the falling edge thereof is defined as an image edge signal. The leading edge of the document is exposed exactly when the image edge signal is applied. Time t8 is t B =12/vK, where vK is the speed of the optical system. On the other hand, as shown in FIG. 54, regarding the relationship between the blank LED 14 and the optical axis 305, the blank LED 14 is located upstream by one intersection. Therefore, the blanking control needs to be performed in advance by l 1 /V p corresponding to the original, where the process beat is Vp. First, the control for creating a 2 mm leading edge margin will be explained. The optical system is scanned as shown in FIG.
Turn off ED24. Here, t9 is t9 = fL
2 + 2 / V K = 11 / V p -cx
/ V p. Here α is a blank LED l
It is 1/2 of the irradiation IJ of 4. By doing this, an appropriate leading edge margin can be obtained in accordance with each multiplication of -44. The speed of the optical system is set to 2, where Ta does not become negative even when reducing copying.

Further, since α does not take a constant value due to variations in the light cost of the LED array, etc., the A value can be adjusted from the operating section as described later.

Next, consider area specification motes. In No. 5814, 310 is a document, the optical system 24 scans in the direction of arrow a, and 311 is a copy area, for example, the range in direction a is set to 100 mm to 150 mm. In such a case, as shown in FIG. 59, t 10
After that, the blank LED 14 is turned off, and from there, the time t 1
After 1, turn on the blank LED 14 to turn on the 5th
As shown in FIG. 8, an image can be displayed only within the specified area 311.

Here, t10 and t11 are In this case, a desired area can be blank exposed.

On the other hand, in Fig. 58, the part that displays the image is reversed, 31
If the value is other than 1, as shown in Fig. 60, the blank LED 14 is turned off after the above-mentioned time t9 from the blurred image tip signal, a margin is created at the tip, and the blank is turned on after time t12 from the image tip signal, and from there. Turn off the blank after time t13. t 12 and t 13 are as follows.

] If you want to display white → image as shown in 2, set α/V p to J
In the case of 1 image - white, by adding α/Vp, a sophisticated area copy can be performed.

Also, as mentioned above, when specifying areas to be copied in different colors at once, in order to prevent color toner and black toner from mixing, each area is narrowed down and copied.1 For example, area 311 in FIG. When copying other parts in red, first copy in black, control as shown in Fig. 59, or reduce t10 by 1mm from (+1'7) described in II. The value is 1ii7 1m from the above value
Increase by m. Next, when making a color copy, the blank LED 14 is controlled as shown in Fig. 60, but the screen 12 is made smaller by 1 mm than the above, and the t13 is made tin by 1 mm.
greater than the stated value. This results in a 2mmmm domain area in the black and color areas. Even if the resist is slightly rubbed, the black and color areas will not mix to any extent.

Explanation of remote settings> FIG. 11 shows 'I [copy mode when the source is on.

This is a flowchart of processing when the reset key 119 is pressed or after a certain period of time has elapsed after the end of copying (auto clear), and processing for inputting duplex/multiple/page continuous copying mode and area designation mode.

FIG. 12 is a flowchart showing details of 5tapl-1. The contents will be explained below. Because it has one battery to hold the contents of RAM, '1
The contents of the RAM are retained even after the power is turned off. For this reason, when the power is turned on, necessary contents of RAM must be retained and unnecessary contents must be cleared (Stapl-1-1), and the copy mode must be set to standard mode. (Step 1-2), this standard mode has the same settings as the standard mode obtained by S when the reset key 119 is pressed. This standard mode includes, for example, 1 set number of copies, 1-size copy, development temperature point, and lower cassette selection.

Next, the presence or absence of key manual input from the operation unit 100 is determined r1 (Stapl-2), and it is determined whether the input is related to area registration. Process. If the reset key is 119 manual (Stapl-4),

When copy mote is changed to mark mote Area Noboru 91,
2.3 is cleared, but the RAM data recorded in area O at 5tapl-6 is not cleared. This happens when the reset I/key 119 is pressed due to a user's mistake.
This causes the inconvenience of having to perform area registration f times. Area registered RA to alleviate this

Explanation of Density Correction> By the way, the following two methods are generally used in copying machines to appropriately set the copy density.

The first method is to set the lamp first arrival for exposing the document to a predetermined value, and the second method is to set the value of the developing bias to a predetermined value.

By the way, a rational method for managing these values is to store the optimal combination of data in the non-volatile data memory inside the copier at the time of shipment, and to adjust the copy density, the user himself/herself adjusts the exposure dial according to the user's preference. It is preferable to configure it so that On the other hand, the process conditions have changed over time, and even if the exposure dial is set to the center (standard density value), the actual copied image is not the same as the standard value. For situations where the SE degree is not reached, the configuration may be such that the developing bias value can be corrected.

However, if the lamp light amount and the developing bias value are stored, for example, in the data RAM, it is necessary to display what value is currently set when adjusting the lamp light amount or the developing bias value. However, unnecessarily increasing the number of display LEDs in the operation display section of a copying machine is inconvenient in terms of cost and also leads to a decrease in operability. Therefore, in this embodiment, the developing bias value can be displayed in the exposure ψ display segment, and the former is lit and the latter is blinking for differentiation.

A method of adjusting the exposure amount and developing bias value in this embodiment will be explained using FIGS. 66 to 69.

In FIG. 66, reference numeral 403 is a three-digit segment display corresponding to the magnification display 154 shown in FIG.
It is also possible to display Bis. Further, 404 is a density display LED l 62, 406, 407 are copy density adjustment keys 114, 405, 408 are copy density correction keys 1
15 respectively. 401 and 402 are data R for each data stored in the data ROM 440, which will be described later.
Data transfer key for storing in AM441, 409
is an extinguishing key for extinguishing the developing bias value blinking on the density display LED 404.

The keys 401, 402, and 409 may be provided on the operating section shown in FIG. 3, but since they are not normally used, it is preferable to provide them inside the copying machine.

Figure 67 shows the data RAM 441 used for adjusting the exposure amount or developing bias value, and each numerical value in Figure 1 indicates each data (+i indicates the data in the data RAM area 441 backed up by a lithium battery). , L-CN
T is an exposure correction index, L-INT is a lamp control voltage value corresponding to the exposure correction index, and L-DAC is scaled to set the value of L-INT to an 8-bit D/A converter. Indicates the area for storing the value. Similarly, D-CNT is L-CNT, D-Bis is L-INT,
D-DAC is a data table of developing biases corresponding to L-DAC.

Further, FIG. 68 shows a data ROM 440 for storing standard data regarding exposure j- and development bias values, and each area L-C of this data ROM 440 is
The NT-D-DAC is connected to each area L- of the data RAM 441.
Compatible with CNT-D-DAC.

Further, each data in this data I'10M440 is set in advance as standard data in order to obtain the optimum copy density, for example, at the time of shipment of the copying machine. All standard data in these data ROMs 440 are copied to data RAM 441 by pressing 119 data transfer key 402. Also, if the data transfer key 401 is pressed, areas I, -CNT and D-CNT of the data ROM 440 can be transferred.
Only the standard data stored in the data RAM 441
copy in the same area.

The aforementioned control unit 60 controls the data RA when executing a copying operation.
The exposure amount and development bias value are determined based on each data stored in M441. FIG. 69 shows the memory L-I NT and D-Bis of the data RAM 441.
The lamp control voltage value and developing bias voltage value stored in the light amount control circuit CVR (not shown) and high voltage generator HV
It is a circuit diagram for setting to T. To explain the figure, when the copy key is turned on and the copying operation is started, the control section 60 controls the lamp control '1 stored in each area L-INT and D-Bis of the data RAM 441 at a predetermined timing to perform pressure and development. The bias voltage value is scale-converted to 8-bit data, and set in the areas L-DAC and D-DAC, as well as in the pulse width modulator 442. The output of the pulse width modulator 442 is converted into DC by a filter 443, and is supplied to the light amount control circuit CVR and the high voltage generator HVT via a buffer amplifier 444.

Next, a method of adjusting the exposure amount and developing bias value in this example will be explained.

When copy density adjustment key 406 or 407 is pressed, I+If in area L-CNT of data RAM 441 is set to "-1".
"° or '+1", and one of the segments 404 corresponding to the value of area L-CNT is shifted in lighting. At the same time, area L of data RAM 441
-For INT.

A predetermined value is subtracted or added. Also, when the data transfer key 402 is pressed, all data in the data ROM 440 is transferred to the data RAM 44.
1, and each area of the data RAM 441 is, for example, L-CNT=8. Each standard value such as L-INT=75 is written, and on the segment 404, the area D-CN
The area corresponding to the value of T "8'° is displayed blinking. At the same time, on the segment display 403, the area D-B
is value "180" is displayed. Then, when the copy density correction key 405 or key 408 is pressed, the value of area D-CNT of data RAM 441 is incremented by "-1" or "+1", and area D-CNT One of the segments 404 corresponding to the value of is blinking and shifted.At the same time, a predetermined value is subtracted or added to the area D-Bis of the data RAM 441.The segment 404 is used for adjusting the exposure amount. In order to distinguish from the above, the segment 404 performs a blinking operation when adjusting the developing bias value. That is, the segment 404 performs a blinking operation when the copy density correction key 405 or 408 is pressed, and the segment 404 performs a blinking operation when the copy density adjustment key 40 is pressed.
When 6,407 is pressed, a lighting operation is performed. still.

If the blinking operation and the lighting operation overlap, the lighting operation is given priority.

In this example, the blinking of the segment 404 can be turned off using the lights-off key 9, but even if the lights-off key 9 is pressed during the lighting operation, the segment 404 is not turned off.

Also, when the copy density correction key 405 or 408 is pressed, the area D of the data RAM 441 is displayed on the magnification display 403.
-Bis value, that is, the developing bias voltage value is displayed.

Note that this display returns to the original magnification display when the copy key is pressed. To specifically explain an example of 3J adjustment, first, by pressing the data transfer key 402, the data RAM is transferred.
441 is initialized, and the standard voltage value of developing bias "180" is displayed on the segment display 403, and the portion corresponding to the standard value "8" and "9" is displayed blinking on the segment 404.Next, the standard original The copy density correction keys 405 and 408 may be operated as appropriate so that the density becomes the appropriate density.

- As explained above, in this embodiment, the display of the development bias shift F, 14 is also used as the display for exposure meter adjustment, so the development/height bias can be adjusted without providing an extra display that is not normally used. can be easily adjusted.

Explanation of the automatic paper selection mode> Next, we will explain the automatic paper selection mode (
(hereinafter referred to as APS mode) will be explained using FIG. 70.

The copying machine of this embodiment can be equipped with multiple cassettes (paper sizes), and has an AP function that automatically selects the most suitable paper cassette according to the set original size and the specified magnification ratio.
It has an S mode. Key 411 in the figure. LED
412°413.414,415,416. key 417
Each of the keys 124°LED1 shown in FIG.
65, 156, 157, 158, 159, corresponding to keys 113.

In FIG. 70, a key 411 is a key for selecting and canceling the APS mode, and a 0 display section 414 whose selection status is displayed by an LED 412 is for displaying all cassette sizes currently installed. be. Further, a par LED 413 indicates the currently selected size among the sizes displayed by the LED 414. However, if there is no paper in the cassette of the 'M'FR size, the LED 413 will not light up. An LED 415 indicates which cassette of the cassette loading port (including the manual feed port) is currently selected, and an LED 416 lights up when there is no paper in the selected cassette. 417 is a cassette selection key, and each time the key 417 is pressed, the LED 41
5 lights up one by one from the bottom to the top.

In the copying machine of this embodiment, when the cassette selection key 417 is pressed after the APS mode is selected, the APS mode is canceled and the LED 412 is turned off. If the original pressure plate 34 is open when the copy key is pressed, the original size cannot be detected, the APS mode is canceled, and paper is fed from the lowest cassette.

By the way, the copying machine of this embodiment can deal with various inconveniences that may occur when selecting the APS mode, such as when there is no optimal paper cassette to be selected, or when the document size cannot be detected due to some circumstances. It is structured like this.

Hereinafter, a method to deal with the case where the APS mode cannot be executed smoothly will be explained.

(1) When the document size cannot be detected --- Release the APS mode and select a predetermined priority cassette (for example, the lowest cassette).

(2) When power is turned on, auto clear temporary, reset key 1
When pressing 19, if a plurality of paper cassettes are not installed, the APS mode is canceled and the only installed cassette is selected.

(3) When no paper cassette is installed, cancel the APS mode and display a paper out display (LED 416 lights up) with the predetermined priority cassette selected. (4) If there is only one paper cassette, Moreover, when the APS key 411 is pressed while a cassette slot with no cassette is selected (no paper is displayed by the LED 416), the APS and LED
412, select the 5th and only cassette, turn off the paper out display, and then turn on APSL.
Turn off ED412 and cancel APS mode.

Explanation of Memory Diagnosis> Next, the nonvolatile data memory diagnosis method in this embodiment will be explained using FIGS. 71 to 73 [Δ].

The copying machine of this example has a nonvolatile data memory 421,
Various control constants 5 such as high voltage output value, exposure voltage value, registration correction (++'i, etc.) are stored in the memory area, and these control constants are read out as appropriate to execute the copying operation. .

Further, the unembodied copying machine has a function of diagnosing whether or not each data read from the nonvolatile data memory 421 is correct as described in , and it is not possible to add such a diagnosis function. This further increases the reliability of the device.

In FIG. 71, 421 is a static RAM (nonvolatile data memory) with a methane/hay function for storing various control constants, and 423 is for performing various controls such as sequence control based on the data stored in the RAM 421. CPU (in charge of the control unit 60 in FIG. 2).

), 422 is a lithium battery, which is used as a backup power source for the RAM 421. 'If source 5v is R
When given to AM421, σE=O and R
The AM421 can be accessed by the CPU 423, but there is no power switch, etc. by'ili
[When 5V is cut off, σT becomes high level and a holding current is supplied from the lithium battery 422 to the boat vDD of the RAM 421. As a result, even if the current is cut off, the data in the RAM 421 is retained by the lithium power supply 422.

Further, in this example, the output voltage of the lithium battery 422 can be monitored by the microprocessor (CPU) 423 when the power supply +5V is in the active state.

In FIG. 72, 428 is a parallel I10 port connected to the CPU 423, and the latching relay 426 can be driven by its output. On the other hand, latching relay 4
What is the condition of 26?

3.

Further, 427 is a button switch for releasing the latching relay 426, which is used when it is desired to initialize the data RAM 421.

Next, the backup power supply 422 and RAM 42 are executed by the CPU 423 using the flowchart in FIG.
The diagnostic operation No. 1 will be explained in detail.

First, in step 430-1 when the power is turned on, the CPU 42
Data retention connected to the A/D conversion input terminal of 3? Ti
The voltage of source 422 is compared with a reference value (for example, 3.OV), and if it is lower than the reference value, the process moves to step 430-6 where a data error is displayed and a user action is requested.

Further, if the voltage of the data holding power supply 422 is equal to or higher than the reference value in step 430-1, the process moves to step 430-2, and it is determined whether the latching relay 426 is on.

When the input of latching relay 426 is off, the process moves to step 430-3 and the data stored in advance on ROM is copied to a predetermined area on RAM 421. Then, it is determined whether or not the copied data can be completely read out from the RAM 421 using the output from the ROM (step 430-4).
1 is determined to be normal, the coil of the latching relay is energized in step 430-5.

If the latching relay is turned on in step 430-2, it is assumed that initialization has already been performed, and the process moves to step 430-4, where data at a predetermined address in the RAM and data at a predetermined address in the ROM are combined. They are compared, and if they match, it is determined that the RAM 421 is normal.

<Description of iN mode> The method of correcting the preset developing bias value has been described above. The following describes the case where the reference value itself is set or changed due to factors such as drum replacement. FIG. 74 is a diagram showing standard values of the adjustable parts of the nine copy positions. These values are stored in RAM.

At the factory, adjustments are made to each machine one by one, and the adjustment values are written on a label affixed to the inside of the machine. When the control board on which the contents are stored is replaced in the market, the RAM is reset according to this label.

Also, when a new value is entered in the market, it is written on this label.

At 160, the standard value is displayed on the magnification display 154.

Next, I will explain how to adjust it.

By pressing a tact switch (not shown) provided outside the operation unit and then pressing the trouble key 121, the number display 160 enters the adjustment mode. 154, the percentage display 153 turns off, and the diagram display 152 blinks, indicating that the change is possible.

In this state, if you input a value directly using the numeric keypad 122 or increase or decrease the value using the zoom key 109, and then press the error key 121 when the setting is complete, the value shown on the copy magnification display 154 will be transferred to the RAM as the content of data number 〇. At the same time as the data is stored, the next adjustment item is moved on, the sheet number display 160 becomes 1, and the value corresponding to data number 1 is shown on the display 154. The same process is repeated up to data number 16.

However, if the trouble key 121 is pressed when the data number is 16, the data number returns to 0 and the process can be repeated cyclically.

Note that whenever you wish to finish this adjustment, press the reset key 119 to cancel the adjustment mode and switch to the standard mode, allowing copying.

Description of Editor ■> A timing chart of coordinate input by the editor 70 is shown in FIG. When the pen switch is turned on, the CPU60
handles coordinate input for the editor. When the pen switch is turned on, the relay 901 is in the on state.

At this time, the editor 70 is expressed by the equivalent circuit shown in FIG. 5-2, and the editor signal DG-X is expressed as the DG-X signal shown in FIG. 75, taking into account the time constant of the electric circuit. Also, when relay 901 is in the OFF state, it is expressed by the equivalent circuit shown in Figure 5-3, and the editor signal DC-Y
Considering the time constant of the electric circuit, DG-Y in Fig. 75
Represented like a signal. CP the editor signal DG-X 30m5ec after turning on the pen switch.
U60 reads. Also, approximately 1m5 after DG-X reading
After ec, relay 901 turns off. Further, the editor signal DG-YQCPU 60 is read 30 m5ec after the timing when the relay 901 is turned off. This 30ms e
c is for preventing the influence of chattering of 901 on the pen switch and relay.

Also, when the pen switch is turned on without the resistor 70 of the editor being pressed sufficiently, the DG-X signal of the editor is
There is a possibility that it will be output after the PU read timing. The situation at this time is shown in FIG. 76. At this time, an error occurs in reading the coordinates of the editor in the X direction.

Furthermore, if the pen switch is released from the resistor 70 of the editor before the coordinates in the Y direction are read, a G-Y signal is generated as shown in FIG. 77. At this time, an error occurs in the read value of the Y-direction coordinate of the editor.

For the above reasons, errors occur in the X and Y readings of the coordinates. Therefore, as shown in Figure 78, after reading the DG-Y signal, read the DG-X again and compare it with the DG-X signal read first. If they do not match, it is treated as an invalid coordinate input. , do not sound the buzzer. Also,
If it falls within a predetermined range, it is considered a valid input. In this way, by comparing the coordinate inputs from the editors, it is possible to improve the reliability of the input data.

A flowchart at that time is shown in FIG.

When the pen switch is turned on (step 79-1), 30
Wait for m5ec (step 79-2), remove pen switch chattering, read DG-X signal, and read DG-X signal.
Xi (step 79-3), then turn off 901 to the relay after about 1m5ec (step 79-4), 30
Wait for m5ec (step 79-5), remove relay chattering, and read DG-Y signal.

DG-Yl (step 79-6), and about 1 m
After 5ec, turn on the relay 901 again in step 79-
7), Wait for 30m5ec (step 79-8), remove the relay chattering, read the DG-X signal, and set it as DG-X2 (step 79-9).

Compare DG-X 1 and DG-X2 (step 79-10), and if the difference is within the predetermined value
It can be determined that the phenomenon shown in the figure or FIG. 77 does not occur. If the coordinate input is normal, step 79-11) sounds a blur and registers the coordinate input (step 79-12).

Also, it is important to improve reliability even with inexpensive editors by disabling coordinate input if it is outside the range of the predetermined value X.

Furthermore, by increasing the number of times the DG-X and DG-Y signals are compared, reliability is further improved.

Explanation of color toner replenishment> Next, toner supply will be explained.

FIG. 80 shows the configuration of a color developing device, and FIG. 81 shows a color toner remaining amount detection circuit. In the figure, 500 is a color developing device, which corresponds to 7 in FIG. 501 is a developing cylinder, 50
2 is a stirring screw, 503 is an AC voltage detection plate, 504
505 is a color toner supply window, 505 is a stirring rod, 506 is a color toner hopper, 507 is a direction in which pressure is applied to the developing device, and 508 is a direction in which pressure is released.

One of the stirring rods 505 is L-shaped and has the role of transporting the toner in the color toner hopper into the developing cylinder 501 when rotating.

In the color toner remaining amount detection circuit 520 shown in FIG. 81, the AC voltage applied to the developing cylinder 501 is taken in by the AC voltage detection plate 503 via the toner, and is input to the input terminal 509. The input AC voltage is rectified by the diode DB+, then input to the positive side of the comparator 510 via the resistor R8I, and compared with the negative side reference voltage v81. Outputs 0'°.

If there is sufficient toner around the developing cylinder 501, the developer will have a high resistance, so the input from the AC voltage detection plate 503 will be a low voltage, and the output of the comparator 510 will be "
0°゛, and conversely, when there is little toner, the resistance of the developer becomes low, so the output of the comparator 510 becomes °゛l.
It becomes °゛.

The output of the comparator 510 is inverted by an inverter 511 and inputted to the control unit 60 as an output 512. Also,
Reference numeral 513 is a timer counter that counts up in response to a toner absent signal and is reset in response to a toner present signal.

In addition, the color toner remaining amount detection circuit operates during copying.
The amount of toner at which it is detected that there is no toner can also be easily determined by changing the reference potential V on the negative side of the comparator 510.

Next, the flowchart shown in FIG. 82 will be explained. Generally, the first sheet of continuous copying is more prone to toner fogging and oversupply than the second and subsequent sheets, so in this embodiment, the sequence is different for the first and second sheets of continuous copying. . When a color copy is performed after the power is turned on, the amount of toner is determined in accordance with (a) for the first color copy. The power is turned on (step 82-1), the color developing device 7 (500) is pressurized against the drum surface (step 82-2), and idles for about 4 seconds (step 82).
-3) To make the adhesion state of the developer on the developing cylinder uniform. Next, the output 512 of the color toner remaining amount detection circuit is read, and it is determined whether or not toner is present (step 82-4); if there is no toner, it is determined whether the toner out signal continues for 10 seconds or more (step 82-5); If it continues for 10 seconds or more, a message indicating that there is no toner is displayed (step 82-6), the copying operation is stopped (step 82-7), and the toner replenishment state is entered (step 82-7).

In cases other than the above, that is, in the case of the second or subsequent sheets, follow (b). Read the output 512 of the color toner remaining amount detection circuit,
The amount of toner is determined (step 82-9), and the timer counter is incremented by 1 each time a toner out signal is received (step 82-10).

In step 82-11, it is determined whether the timer is within 5 seconds,
If it is within 5 seconds, move on to copy operation (Stella:y”82-
14) If the time is 5 seconds or more, the copy operation does not proceed, and the signal is constantly monitored in steps 82-9 to 82-12. In step 82-12, it is determined whether the timer is 10 seconds or more,
If the time is longer than 10 seconds, display “out of toner” Step 82-
15) and stop the copy operation (step 82-16).
Toner replenishment is performed and the timer counter is reset in step 82-13 when toner is present. Note that the toner out display may be performed after a series of operations are completed as described above.

Further, in this embodiment, a color toner developer has been described, but it goes without saying that the present invention can be applied to all two-component developers. In addition, in this embodiment, the AC bias detection plate is one plate, but if this is divided into a plurality of plates and connected to the remaining toner amount detection circuit by a well-known switching means, the remaining amount of toner can be detected. It is possible to partially control the amount of toner in the developer within the device.

[Effects] As described above, according to the present invention, specified coordinates can be recognized accurately, reliability of coordinate input can be improved, and unnecessary image formation can be prevented.
