[0007]

If the user presses the stop button while the automatic document feeder is operating, or if an emergency stop cause such as a jam or interlock occurs in the main body of the image processing apparatus, the original document feeding path of the operating automatic document feeder is The original can be forcibly discharged from the conveyance path.

Further, when it is judged that the size of two or more originals drawn by the automatic document feeder is irregular, the originals in the document conveying path of the automatic document feeder in operation are forcibly conveyed. It can also be discharged from the road. However, when the sizes of two or more originals are irregular, it means that the mode in which image processing is not performed is set.

Further, in the case of having an original parallel composition function of combining two or more originals set in parallel at the original registration position on the platen of the image processing apparatus main body to perform image processing, an automatic original is provided. Even when it is determined that the odd-numbered original document and the even-numbered original document drawn by the feeding device are different from each other, the original document in the original document feeding path of the operating automatic document feeding device is forcibly conveyed. Discharge from the road.

When the operation stopping means of the image processing apparatus main body is input, if the image processing apparatus main body is operating,
If the carriage of the paper from the paper supply tray is newly stopped and the carriage lamp has already been scanned for the paper that is already being conveyed in the paper conveyance path, the image processing for the number of sheets already started is carried out. Let it do and eject the paper. Therefore, for example, if the set button is 5 and the stop button is pressed when three sheets have been conveyed, the three sheets are already being conveyed, and image processing for that portion is surely executed. Then, the image processing apparatus is shifted to the stopped state. Also, if the original irregular size is detected when the original parallel composition function is set, scanning of the carriage lamp starts after detecting the size of the even-numbered original.In this case, the main body of the image processing device is stopped without feeding the paper. Let

Further, even when the irregular size document is conveyed to the document registration position by using the automatic document feeder and the irregular size of the document is detected when the image processing mode is not set, the original document is regarded as the preceding document. Since scanning of the carriage lamp has not started for a document that is determined to have an irregular size, the sheet that has already been conveyed corresponding to the document is discharged as it is without image processing.

The characteristic part of this embodiment will be described below. First, the structure of the DADF 2 of this embodiment will be briefly described. The DADF 2 of this embodiment is an ADF capable of automatically feeding both sides of a document.

FIG. 7 shows a sectional view of the DADF 2. DAD
A document tray 61 is provided at one end of the central portion of F2, and a document discharge tray 62 is provided at the other end. Then, in the document carry-in portion, first, the document 63 is conveyed to just before the platen 65, and the feeding and conveying path 66 is used to convey the original 63, and the saddle (SADH: semi auto document handler) conveying path 6 is a manual document conveying path.
7 and a document feed-in conveyance path 68 and a duplex conveyance path 69 which is an original conveyance path for double-sided copying. A document registration unit (hereinafter referred to as a document registration unit) is provided with a rubber endless belt 71 driven by a belt drive roll 70 using a belt drive motor (not shown) as a power source. This belt 71 is attached to the platen 17 at the rear end of the original 63 sent from the original carry-in section.
The document is stopped at the upper registration position 64, and the document surface is scanned by the carriage lamp 19 (FIG. 4) and then sent to the document unloading section having the discharge tray 62. A registration sensor 72 and a document size sensor (not shown) are arranged at a widthwise setting position of the document feeding path 68.

The DADF 2 having the above structure has the following five types of running modes. First, the transport mode for copying only one side of the original 63 that does not differ in size is
Called simplex mode. In this simplex mode, high-speed copying is possible by transporting the next original 63 to the registration position before the original 63 that has undergone the original reading process is not completely discharged.

In the duplex mode, which is a conveyance mode for copying both sides of the original 63, the original 63, which has been set at the registration position from the feeding conveyance path 66 and has finished the copying operation, is reversely conveyed to the duplex conveyance path 69, and In this mode, the back surface is set at the registration position on the platen 17. Therefore, after the one-sided copy of the original 63 at the original registration unit, the drive motor (not shown) of the belt drive roll 70 is rotated in reverse, and at the same time, the registration gate (not shown) is rotated upward, so that the duplex conveyance path 69 is formed. The document 63 is opened and conveyed to the duplex conveying path 69. Then, when the trailing edge of the original is set to the registration position on the platen 17 again via the duplex conveying path 69 and the feeding conveying path 66, the back surface of the original 63 can be copied.

Further, the third running mode of the DADF 2 is referred to as a mix (original) size mode, and is a mode for copying a plurality of originals 63 of different sizes in sequence, and only one side thereof is selected. Is operated by.

The fourth running mode of the DADF 2 is called an automatic counting mode, which is a mode in which the original 63 can be conveyed and the number of originals can be counted as in the simplex mode. This automatic count mode can be set when only originals 63 of the same size are conveyed.

The fifth running mode is the original parallel composition mode, so-called 2 in 1 mode. So-called 2 in
One mode will be described in detail below. So-called 2i
The n1 mode is a mode in which two originals 63 having different sizes are continuously conveyed onto the platen 17 and two sheets are simultaneously copied. The size of the original to be copied to be transmitted to the base machine 1 is, in principle, the size of two originals 63 of the same size arranged in parallel. As a general rule, the size of a document to be copied to be transmitted to the main body of the base machine 1 is a size in which the document size of each sheet is arranged in parallel. FIG. 8 and FIG. 9 show schematic diagrams of so-called 2 in 1 mode document conveyance, and the outline of document conveyance will be described.

At least two originals 63 are DADF2
The original tray 61 is set. Then, a feed motor (not shown) provided in the feeding conveyance path or the saddle conveyance path 67 is driven to move the lowermost original (the odd-numbered original) after the leading edge of the original 63 reaches the registration sensor 72. Carry it until it passes a certain distance. Then, by driving the belt motor for a certain period of time, the document is conveyed so that the rear end of the document is located at the registration position 64, and here the document conveyance is temporarily stopped. Next, the even-numbered original 63, which is the next original, is replaced by the odd-numbered original 63, which is the lowermost original.
Send it in the same way as. Next, the odd-numbered original document 63 is reversed to the duplex conveyance path 69 by a predetermined distance. Then, when the belt motor is driven so that the trailing edge of the fed even-numbered original 63 is located at the registration position 64, the even-numbered original 63 is moved to the next even-numbered original 63. The original document 63 is set on the platen 17 without any gap. Then, the odd-numbered original document 63 and the even-numbered original document 63 are copied in parallel. After this copying, the two originals 63 are discharged. In this way, for all originals, two sheets of parallel composite copying are sequentially performed.

In this embodiment, the discharge control of the original 63 is performed in the case of an abnormality such as the operation of the base machine 1 being stopped while the DADF 2 is being used.

The operation of the base machine 1 is stopped by the user pressing a stop button, or the base machine 1 is stopped urgently due to a jam or an interlock in the base machine 1.

Also on the DADF 2 side, if the irregular size is conveyed without selecting the mixed size mode, in this case, the DADF 2 is treated as a jam, so the original 6
Stop the transportation of 3. These controls are LLM48 and DA
Communication is performed with the DF controller 41.

First, the document discharge control in the transport path of the DADF 2 when the operation on the base machine 1 side is stopped will be described. In this case, the document in the transport path of the DADF 2 is forcibly discharged. FIG. 10 shows a flowchart of the document discharge control when the stop button is pressed during the copying operation using the DADF2. If a stop button is pressed while performing a copy job using the DADF 2, the conveyance of new paper 27 from the paper supply tray 25 of the base machine 1 is stopped (step 3). Then, a copy job is performed on the already conveyed sheets 27, and when the number of the copied sheets 27 is output to the sorter 3 in advance, the operation of the base machine 1 is stopped (step 5). Then, after that, a forced discharge command for the original 63 is issued to the DADF 2. Then, when the document 63 is forcibly discharged, the base machine 1 becomes ready and waits for a button operation by the user. For example, if the stop button is pressed when the copy job for three sheets is finished in the copy job for the set number of sheets of five, the feeding of the fourth sheet 27 is stopped, and the first three copy sheets 27 are left. The operation of the base machine 1 is stopped after a while after passing through the fuser sensor 73.

Next, if there is a jam or an interlock in the base machine 1 during the copy operation using the DADF2, the DADF2 will be processed as shown in the flowchart of FIG.
A document forced discharge command is issued to promptly discharge the document 63 in the DADF2 transport path.

FIG. 12 shows the flow of forced document ejection when the stop button is pressed in the base machine 1 when the automatic count mode for counting the number of documents is selected by using the DADF 2 before copying. Here, DADF
The outline of automatic counting using 2 is performed in the following procedure.

Normally, the count of the same size originals is L
The DADF controller 41 receives the start signal of the DADF 2 from the LM 48 and is activated, and the pulling of the next original 63 is started after a certain time has elapsed since the leading edge of the original 63 reached the registration sensor 72. Then, the number of sheets is counted by the number of times the document is passed by a discharge sensor (not shown) in the document discharge path. Further, the same procedure as described above is carried out for a document of a different size, but the drawing of the next document is carried out when the previous document has passed the discharge sensor.

As shown in FIGS. 10 to 12, when the operation of the base machine 1 is stopped, the original 63 in the transport path of the DADF 2 is transferred.
By forcibly discharging the document, the troublesome document removing work is unnecessary, and the document 63 is not left in the transport path of the DADF 2.

Next, FIG. 13 shows a control flow chart for detecting the irregular size original document when the irregular size mode is not selected by using the DADF 2. If the paper size sensor such as the registration sensor 72 of the DADF 2 determines that the size of the second and subsequent originals is different from the size of the transported original 63 before the irregular size mode is not selected, the base machine 1 determines Cycle down. That is, when the original size detection sensor of the DADF 2 determines the irregular size, the original 6
Since the scanning of the carriage lamp 19 for 3 is not started, if there is a sheet 27 that has already been conveyed corresponding to the original 63, the sheet 27 is ejected without copying it. Then, the base machine 1 is stopped and the caution message is displayed on the LCD screen 36 of the console panel 4. At this time, as for the document 63 in the transport path of the DADF 2, as shown in FIG.
F2 is forcedly discharged.

Further, FIG. 14 shows a control flow when a document 63 of a size that cannot be used for a copy job is sent in the document parallel composition mode, so-called 2 in 1 mode. In the so-called 2in1 mode, for example, A4SEF (S
(Hort EdgeFeed) and B5SEF originals are often impossible to be combined in parallel.
Base machine 1 by the size detection of the original size sensor
Also, the LCD screen 36 displays a caution message without feeding the paper.

Here, a method of detecting the original size of the DADF 2 will be briefly described. First, SEF and LEF of original 63
A size detection method including (Long Edge Feed) will be briefly described. The LEF is a conveyance method in which the longitudinal direction of the original document is set to the front. The width of the document 63 is detected as follows.

As shown in FIG. 15, the document size sensor 7
Since there are Nos. 7 and 78, it can be seen that the combination of ON / OFF of these two size sensors belongs to any one of the "documents" shown in the left column of the tables shown in Tables 1 to 3.

Next, regarding the document length, the value of the timer of the CPU of the DADF 2 is read at the time of detecting the document leading edge and the document trailing edge of the registration sensor 72, and 664 pulses (1.29 m) of the reference clock are read.
s) is multiplied by the detection reference length of the stepping motor, and from the obtained value, the distance between the registration sensor 72 and the registration roll 134 and the movement distance during the step-up of the rotation speed of the belt motor can be calculated by subtraction. it can.
