Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a pudding machine equipped with a plurality of developing devices each having a developer of a different color. - In particular, it relates to a printer that can print colors by dividing them vertically or horizontally.

[Background of the invention and its problems] Printers that are connected to a host device such as a word processor or a business personal computer and print out various data such as characters, figures, images, etc. as hard copies are becoming more and more popular due to the increased functionality of the host device and color printing. With the demand for diversification of printing modes, color printing equipment has become available.

On the other hand, for electrophotographic copying machines, a control method has already been proposed in which multi-color copies are made simultaneously in - number of copying operations by selectively switching and driving a plurality of developing devices each having developers of different colors. There is. In this case, the area of the electrostatic latent image on the photoreceptor to be developed for each developer is specified by moving a lever on the operating knob or inputting coordinate designation while viewing the copy document.

Even in the case of a printer, it is possible to print in multiple colors within one printed page by providing multiple developing devices and performing switching similar to the switching of the multiple developing devices in the copying machine. .

However, the host device displays various data such as characters, figures, images, etc. on a CRT screen, and when printing in multiple colors by changing the developing device within one page to be printed, as in the case of a copying machine, In this case, it is not possible to directly specify the switching position of the developing device on the operation panel by looking at the copy original and associating it with the original. In addition to being troublesome to find the position, there are also inconveniences such as the inability to accurately determine the switching position. Furthermore, in the case of printing by vertically or horizontally dividing two colors at the same time, the paper feeding direction must also be considered.

An object of the present invention is to automatically select a paper feed cassette with the correct paper feeding direction from the installed paper feed cassettes according to the vertical or horizontal color-coded image data that is set and sent by the host device and output the printout. The objective is to provide a printer that can perform this.

[Means for Solving the Problem] The above object is to provide a host device with a plurality of developing devices each having a different developer, and to set a developing device switching timing for selectively switching and driving the plurality of developing devices. In printers that use signals from The division setting is achieved by providing means for automatically selecting paper feed cassettes in which the paper direction is vertical.

[Function] For simultaneous color (simultaneous multi-color) printing, two paper feed cassettes of the same size are installed, one for vertical and one for paper feeding directions, and the other for documents of the same size, one for vertical and one for horizontal feeding. When documents are mixed in random order, the paper feed cassette with the correct paper feeding direction is automatically selected depending on whether the document is vertically or horizontally fed each time each document is copied, so the operator can check the document while looking at the document. There is no need to switch and operate the paper feed cassette selection button one by one.

The print data transmitted by the host device 71 through path (2) includes image data, developer control information, and division information (paper selection).

Upon receiving this print data, the controller 72 creates an actual print image (bitmap) from the image data, and sends it to the printer engine 73 via pass (2). Further, the developing device control information and J[[selection information are sent to the printer engine 73 as status information via path 3. The CPU 74 of the printer engine 73, which has received each information through the passes ■ and ■, drives the printer based on this information, and also drives the light emitting body (leather) 75.

FIG. 9 is a flowchart showing the main routine of control of the controller 72 (step 3100).
) (hereinafter abbreviated as "Step 1"), a data input routine is executed, and image data and @ control data for the printer are received from the host device 71. (SIO
In I), an image creation routine is executed and image data is developed into an image buffer. Next (S 102)
Then, routines indicating various states of the printer are executed, and control data for the printer is processed.

The control data includes data such as developer selection, instructions for simultaneous two-color printing, developer switching timing for simultaneous two-color printing, paper feed slot selection, mode settings for various attached functions, etc. Contains instruction data. This routine will be detailed later. Next, in (S103) it is determined whether a print request has been made from the host device, and if there is a request (YES in S103), a command to actually start the printer is output (S10).
4).

In this case, the controller 72 is in a mode for outputting image data. Furthermore, once the printing mode is entered, the printing mode is basically continued until the printing is finished (S105), and the normal loop is resumed once the printing is finished.

FIG. 10 is a flowchart showing an instruction routine for various states of the printer described above.・There are many printer status instructions in addition to paper feed selection, mode settings for various attached functions, etc. as mentioned above, but in this routine, in order to explain the execution of the two-color simultaneous print mode, The settings are limited to three items: device selection, simultaneous two-color print instruction, and simultaneous two-color print area instruction.

First, in step S200, it is determined whether the instruction is to select a developing device or not.
If it is ES, it is determined whether the first developing device is selected (S201), and if it is selected, the use of the first developing device is set (S202), and if it is not selected, the second developing device is set.
The use of the developing device is set (S203). Then (S
In step 204), it is determined whether or not a simultaneous two-color print instruction has been issued, and if there is no instruction (No in step S204), the normal print mode is set (step S205). The normal print mode is a print mode in which the entire surface of one page is developed using the selected developer. Said (S204)
If simultaneous two-color printing is specified in , the simultaneous two-color printing mode is specified (3206). Further, the process proceeds to (S207), and it is determined whether the instruction is for simultaneous two-color print area data, and if YES, simultaneous two-color print area data is set. If so (S211)
, 5213, the cross-passing cassette selection is specified, and N
If it is O, a vertical cassette selection designation (32'12) is performed. Subsequently, in (S209), other printer status instructions are determined, and various status settings are made for the printer in accordance with the instructions (S210). Various status settings for the printer here can be made, for example, in R, which can be commonly accessed for printers and printer engines.
A method may be used in which data is set in the AM area, or a method in which data is updated and set at any time through serial communication may be used. ' Also, to set the simultaneous two-color print area data, express the distance from the leading edge of the paper in "mm", replace it with hexadecimal data that is easy to handle for the printer engine interface, and use it as status instruction data to the printer. It is done by handling. For example, when switching the developing device at a position 100 mm from the leading edge of the paper as shown in FIG. 11a (a), hexadecimal data 64H is treated as printer status instruction data. Furthermore, the same figure (b), (C)
As shown in , it is also possible to set simultaneous two-color print area data based on the number of lines from the leading edge of the paper or the number of rasters. In the case of FIG. 11a, horizontal division is specified, and at this time, vertical threading of the paper is selected. Here, the arrow in the figure indicates the paper passing direction. FIG. 11b shows an example of two-color printing with vertical division specified, and in this case, horizontal running of the paper is selected.

FIG. 12 shows the flow of the main routine for controlling the printer engine, and initial settings of the printer engine are performed in (S300). Next, the main loop is entered, and an input processing routine and an output processing routine are executed in (S301) and (S302), respectively. In (S303), it is checked whether there is a print command from the controller, and if there is a print command,
Proceed to (S306) and check the designated paper size.

If the specified size is not found by this check (S307
), the process jumps to (S305) and waits until the specified size is set. On the other hand, if Yes, (S
304) is performed, the loop management (loop time management, etc.) routine of (S305) is executed, and the process of (S304) is performed again.
The process returns to the input processing routine of 301). (S
303), if there is no print command, the above (S3
05) is executed, and similarly (S30
Return to the input processing routine of 1).

FIG. 16 shows the paper selection process (S306).

Here, a paper feed cassette is selected according to the designated paper size, and lighting data for the corresponding cassette selection display LED is set. First, in (S500), the specified paper size (size and direction) is set to the first cassette 20.
It is determined whether the second cassette 21'' is set in the same manner in (S501),
Also, in (S502) it is determined whether the paper is set in the manual slot (manual feed slot), and if both are NO, it is determined that the specified paper is not available, and if the next data to be printed is the first page (S503). ), blink all cassette selection display LEDs 85, 86, 87 (S504
), prompts the operator to load a cassette with the specified paper size into the cassette opening.

(S505), it is determined that there is no paper and the printing operation is not started.

On the other hand, if there is designated paper in (S500), the first cassette is set as the paper feed slot, and the first cassette selection display LED 85
is specified to be turned on, and the second cassette selection display LED 86 and manual selection display LED are specified to be turned off (S5
06). If YES in (S501), the second cassette is set as the paper feed slot, LED86 is specified to be turned on, and LED85.8 is specified.
7 is designated to be turned off (S507). Furthermore (S 502
), if YES, set the manual slot as the paper feed slot and turn on the LED.
Specify LED 87 to turn on and LED 85.86 to turn off (3
50B).

In step (5511), printing is permitted as the specified size exists, and the process returns.

If it is not the first page in (S503), (S509
), if the previous page is the first cassette (S510)
At this point, blink data is set on the second cassette and manual display section to prompt the cassette to be replaced.
In (S512) and (S513), the second cassette is similarly checked and the same display data is set, and in (S514) the first and second cassettes are blinked because the previous time was manual.

The display of the cassette on the operation panel is determined by the above routine, and the actual output of such display and turning on/off is performed in the output routine shown in (S302) in FIG. 12.

FIG. 17 is a partial top view of the operation panel.

In this figure, 82 is a cassette selection switch.

Note that the toner selection switch 81 and the display sections 83 and 84 are not particularly relevant to the present invention.

FIG. 13 shows the contents of the sequence processing routine (S304). In (S310), a roller processing routine is executed, and the paper feed/discharge rollers are controlled to feed/discharge the paper. In (S311), a laser (IT light) processing routine is executed to control 0N10FF of the laser.

(S312) is another processing routine,
Processing is performed when an abnormality occurs. Subsequently (S313)
A developer processing routine is executed to control switching of the developer in the simultaneous two-color print mode.

The setting and control of the switching timing of the developing device in the simultaneous two-color print mode is performed using the laser (
(Exposure) processing routine (S311), and actual switching is performed in the developing device processing routine (S313).

FIG. 14 is a flow chart showing the contents of the laser (exposure) processing routine.

The printer engine 73 that has received the print permission from the controller 72 enters the sequence processing process as described above, but first checks 0N10FF of the laser as shown in (S320) in FIG. 14. In this case, since the laser is initially OFF, it is checked in (3321) whether there is a request to turn on the laser (exposure), and if there is a request, the laser is turned on (S322), and
Reset the print area counter (S 323
) as the print start position. Next, when the main loop goes around once and returns to the sequence processing loop again, the sensor turns on.
/ Laser turns on with OFF check (S 320)
Therefore, increment the print area counter 5324), [S325), (S
327) are the timer setting time (TI) and (T2), respectively.
It is checked whether or not the timer has been set, and if it has been set, the timer setting times (T1) and (T2) are decremented (S326) and (3328). The increment of the counter in the print area indicates that the exposure has progressed for the time it takes to go around the main loop after the start of laser exposure, and the decrement of the timer setting time controls the timing of switching the developer.

The timer setting time (TI) and the role of (T2) will be explained later.

FIGS. 15(a) and 15(b) show the developing unit processing routine (S31
3) is a flowchart showing details of step 3).

First, in (S400), it is checked whether or not the simultaneous two-color print mode is in effect, and if it is not the simultaneous two-color print mode but in the normal print mode, only one of the two developing units is selected in (3401) to (S405). select drive,
The same color is printed over one page. That is, if the first developing device is selected in (S401), the second developing device is set to 0FFL, (S402), and the first developing device is set to O.
Do N (5403). If the second developing device is selected, the first developing device is set to 0FFL (3404) and the second developing device is turned on (S405).

If the simultaneous two-color print mode is selected in (3400), the process proceeds to (S406>) and determines whether the initial developer for the simultaneous two-color print mode has been set, and if it has not been set, In step S407, the initial developer is set.Next, in step S408, the simultaneous two-color print area data given from the controller 72 and the area counter incremented in the sequence processing routine (laser Cn light) are set. It is determined whether the contents match or not, and if they match, each (S 4
09), proceed to (S410), set timer (2) for (T1) time, timer (2) for (T2) time, and turn on the 'timer set flag (S411).

Here, the timer setting times (Tl) and (T2) will be explained. The contents of the print area counter indicate information on the currently exposed position, and the time required for the currently exposed exposure point to reach the developing position of the first developer/detector 4 (Tl
), and the time it takes to reach the developing position of the second developing device 5 is (
T2).

That is, in FIG. 2, the time it takes for the current exposure point W to reach X (Tl) and the time it takes for the current exposure point W to reach X' (T
2). And time (T1), (T
2) is the circumferential speed of the photoreceptor drum 1 Vmm/sec, g
The circumference from the light point W to the developing position X of the first developing device 4 is J.
mm, and the circumference of the second developing device 5 to the developing position X' is Kmm.
Then, (TI) and (T2) are obtained by the following equations.

(TI)=J/Vs e c.

(T2)=to/Vsec.

In this way, the timer 11■ shown in (S409) and (S410) is used to measure the time lag from the exposure position W to each development position It is set at the moment the timer starts counting.

Further, the timer setting times (TI) and (T2) are sequentially decremented in the laser (g-light) processing routine described above, and the time measurement progresses.

If the simultaneous two-color print area data and the contents of the area counter do not match in (3408), (S4
Proceeding to step 12), it is checked whether the timer set flag is ON or not, and if it is not ON, this routine ends. When the timer set flag is ON (S41
If YES in step 2), the time-up of the timer setting time (Tl) and (T2) is checked in steps (S413) and (3418). (S413) sets the timer setting time (TI
), the timer setting time (
5414), and the first developing device 4 is turned on.
If it is working (YES in S415), the first
The developing device 4 is set to 0FFL (S416), and if it is OFF, the first developing device 4 is turned ON and the first developing device 54 is switched.
Also, when it is confirmed that the timer setting time (T2) has timed up in (3418), the timer setting time (T2) is reset (5419), and if the second developing device 5 is turned on and operating (YES in S420). ), the second developing device 5 is set to 0FFL (S421), OF, if it is F, the second developing device 5 is turned ON and the second developing device 5 is switched (S422
) and reset the timer set flag (S42
3). In this way, the switching drive of the developing device is performed without being influenced by the initial setting developing device.

In this embodiment, simultaneous two-color printing is achieved by selectively switching and driving two developing units, but simultaneous multi-color printing can also be achieved by selectively switching and driving three or more developing units. .

Further, as described above, the controller 72 creates an actual print image (bitmap) based on the image data and control data sent from the host device 71, and among the control data, the setting data for vertical and horizontal division is Processing such as rotating the image based on the paper passing direction or in accordance with the paper feeding direction is performed.

Furthermore, a collating function may be added to the copy sheets automatically ejected according to the present invention.

[Effects] As is clear from the description of the specific configuration and embodiments described above, the present invention provides switching timing settings for selectively switching and driving a plurality of developing devices having different color developers. Since this is done using signals sent from the host device, it is possible to change the developing device in the printer within one page to be printed, easily realizing simultaneous multi-color printing, as well as vertical and horizontal division. Automatically switches and selects the paper feed cassette with the paper feeding direction according to the paper feed direction, making it easy to use.

If the paper feed cassette in the selected paper feeding direction is full of paper, the process stops at -.
