The movable mirror 31da stops moving to the right in the figure and immediately starts moving in the opposite direction (to the left in the figure). The above-described operations are repeated according to the number of copies specified in advance by a number-of-copies instruction key (not shown) provided on the operation section. When the exposure for the specified number of sheets is completed, the document illumination lamp, movable mirror 3. The robot returns to the predetermined position indicated by the solid line in the figure and stops. Note that the speed of movement of the document illumination lamp 2 and the like to the left is faster than the speed of movement to the right to improve copying efficiency.

The photosensitive drum 7 has a photosensitive layer covered with a transparent insulating layer, and rotates in the counterclockwise direction as described above. As the photosensitive drum 7 rotates, the photosensitive drum 7 is first subjected to charge removal by a pre-act remover 9 to which AC high voltage current is supplied from a high voltage power source (not shown), and at the same time is exposed to light by a lamp 10. Charges on the surface of the insulating layer and inside the photosensitive layer are erased, and then charged to (+) by a primary charger // supplied with a (+) high-voltage current from a high-voltage power source. The photosensitive drum 7 continues to rotate, and when the (+) charged portion reaches the exposure section 1, the image from the illumination section 12 is exposed (slit), and at the same time, an AC high voltage current is supplied from the high voltage power source. AC static eliminator/3K removes static electricity from the AC static eliminator.

Move to. At step 839', a sorter control routine, which will be described later, is performed, and the process further advances to step 880, where a cover button routine, which will be described later, is performed. After this, steps S3da and 3j are performed again.

74, 37, and 31 to perform copying. In this way, the preset number of copies of nine sheets is completed, and after death, the process moves from step Bit to step 1179K.

Here, the sorter control routine of step S39 will be explained using the first diagram. First, in step 8100, it is determined whether or not the sorter instruction button /j≦ is pressed.
/Distinguish by sorter. If the flag F/sorter is in the reset state, the process moves to step 5iot, and the transfer path switching lever 9j, which should store the transfer paper from the main body 00PY to the separate storage tray 9-2, is moved and set to the solid line position in FIG. 7. .

Thereafter, in step 8107, a storage chamber is opened to store the transfer paper in the tray holder, and the process moves to step siot. However, if the sorter instruction button /It is pressed, the process moves from step 5lO0 to step S10/. In step BID/, it is determined whether the sampling button/It is pressed and the number is 9 by sampling 7 lags F/. If flag F/sampling is set, step f3
The process moves to step 102, where it is determined whether copying has been completed and the transfer paper is the I-th sheet. If it is the I sheet, the process moves to step sio, i.In order for the operator to easily check the transferred image on the first sheet of transfer paper, in the same way as step 8106, the conveyance path switching lever j is moved to the step sio, i. Set it at the solid line position in Figure 1 and send it to the tray 92 in the 7-eighth up state. For the transfer sheets after the λth sheet, in step 510II, the switching lever 91 is set to the position shown by the broken line in FIG. / Store in -rn. In step 8iot, it is determined whether the copying of the main body C0PY is completed. , if the process has not been completed, the process proceeds to step SO in the figure. If copying is completed, proceed to step 5.
Go to 109, i1 line L, and determine sampling function F/sampling. If it is in the set state, the simple editing process described above is performed. That is, since the sampled transfer papers are conveyed to the separate storage tray 2 in order from the 7th sheet in a 7-eighth-up state, the transfer papers are stacked in this tray 9 with the page order reversed. Therefore, after copying is completed, the transfer paper stacked in reverse order is transferred to the roller tO.
By S, the transfer paper is fed in order from the first sheet on the lower side and stored in a predetermined empty bin 91. As a result, the transfer sheets are sequentially stacked in a predetermined empty bin in a 7-eighth down state, starting from the first sheet, and the pages are aligned. Such a simple editing processing operation is performed in step S/10Nf3//. When it is detected in step 8 that there is no more transfer paper in the separate storage tray λ, the process advances to step sho in FIG.

Next, in the recovery button routine of step 8 and 0, as shown in FIG. Set Fugu r/Recovery, set 7 Ladder F/5 TOP to instruct stop mode, and return to step s3 in FIG.

When the operator determines that the transfer paper ejected to tray 9 of the sheet sorter SORTE is an abnormal image in the sunfling copy mode and presses the recovery button In, step 8
From step 37, the process jumps to step 87F in Figure 1 along the flow of rYIcsJ, performs post-copy rotation processing, and stops the 1-drive operation. In the next step sro, until the recovery button isJ is pressed, a storage operation is performed to store the second and subsequent sheets of transfer paper fed from the power unit into the sorter bin group, and then in step Sr /In,
Recovery control processing, the details of which are shown in Figure 1#, is performed.

That is, in FIG. 1, the flag F/recovery that is set by pressing the recovery button in step 8120 is determined. If it is in the set state, step S/
The process moves to λl, and the number of abnormal image transfer sheets that have been copied is confirmed. Next, in step S/here, sorter 5
While driving the shredding device V3t in the ORT,
The abnormal image 9 transfer paper already stored in the sorter bin 9/ is discharged toward the shred section 93 by rotating the roller tl# in the reverse direction (in the direction of arrow 9λ1 in FIG. 2). The above operation is carried out in step S/JJ, and the abnormal image transfer sheets that have already been copied are discharged from the sorter and bin until the number of sheets is exhausted.

In step S/col, the sensor 887 detects abnormal image transfer paper being conveyed to the shredding section 93, and
s/2≦Tea The number of sheets of abnormal image transfer paper conveyed to the shredding section 97 is counted based on the detection output. Further, when the ejection operation of displaying the count value on the counter display/71K of the operation section/70 is completed, the process proceeds from step SlJ to step S/here, and the shredding device 9J/ is stopped.
