2 shows a combination of a copying machine and a post-processing device 50. First of all, the structure of the copying machine is explained.
An automatic document feeder (AD) that automatically conveys a document and sends it from the platen to a predetermined image reading position and then to the document outlet
F) 70 is provided. A transparent contact glass 1 is arranged at an image reading position below the automatic document feeder 70, and an optical scanning system 20 is arranged below it. In the copying (image forming) mode, the original placed on the contact glass 1 is exposed by the illumination lamp 21, and the reflected light from the original is reflected by the first mirror 22, the second mirror 23, the third mirror 24, Lens 25, fourth mirror 26,
An image is formed on the surface of the photoconductor drum 2 arranged in the printer section via the fifth mirror 27 and the like. Around the photosensitive drum 2, a charging charger 3, an eraser 4, a developing unit 5, a transfer charger 6, a separation charger 7, a cleaning unit 8 and the like are provided. The photosensitive drum 2 is
After being cleaned by the cleaning unit 8, the surface thereof is uniformly charged to a predetermined high potential by corona discharge from the charging charger 3. When the charged surface of the photoconductor drum 2 is irradiated with the reflected light from the document, the surface potential of the photoconductor drum 2 changes according to the intensity of the irradiated light, and the potential distribution corresponding to the light and shade distribution of the document image. That is, an electrostatic latent image is formed on the photosensitive drum 2. When this electrostatic latent image passes through the developing unit 5, it attracts toner according to the potential distribution and forms a visualized toner image.
On the other hand, 3 provided with paper feed cassettes 11, 12 and 13 respectively
Any one of the three paper feed systems 30 feeds the transfer paper in the paper feed cassette one by one, and the registration roller 1
The transfer paper fed by 4 is fed so that the transfer paper overlaps the toner image on the photoconductor drum 2 in synchronization with the image forming timing on the photoconductor drum 2. Further, the toner image is transferred onto the overlapping transfer paper by the bias of the transfer charger 6. The transfer paper on which the toner image has been transferred is further separated from the photoconductor drum 2 through the separation charger 7, and the fixing device 1
After fixing the toner image through 0, the toner image is sent to the post-processing device 50 through a predetermined paper discharge path. During the double-sided copying process, the transfer sheet after the single-sided copying process is not fed to the post-processing device 50, but is re-fed by the double-sided transport unit 80. When the transfer and separation of the toner image are completed, the surface of the photoconductor drum 2 is cleaned again by the cleaning unit 8 to prepare for the next copying process.

The transfer paper sent to 0 is sent by the transport roller 53, and the toner image on the transfer paper surface is exposed and heated by the halogen lamp 51. By the way, the transfer paper is heated in advance by the fixing device 10 of the copying machine by the time it reaches here. The strong light and heat of the halogen lamp 51 make the toner image transparent. Roll 53
The mark on the back side of the transfer sheet sent by the sensor is read by the sensor 54, and if N marks are attached, the gate claw 57 is rotationally driven about 60 degrees counterclockwise and the transfer sheet is moved to the first position. 2 It is sent to the tray 60. If there is no marking or less than N markings on the transfer paper, use the stamper 55 to add another marking.

The contents of 4) are shown in FIG. Here, the carriage carrying the sensor 54 and the stamper 55 is driven forward, and the detection signal of the sensor 54 is monitored during that time, and the number of detected marks is incremented by one each time a mark is detected. When the mark is no longer detected, the solenoid 55S of the stomper 55 is energized if the number of detected marks is less than N. As a result, one mark is added. When the number of detected marks reaches N, the solenoid 58 is energized. This allows
Transfer paper with the number of detected marks less than N is placed on the first tray 59,
The transfer paper having the detected mark number N is sent out onto the second tray 59. The transfer paper thus decolorized can be loaded into the cassettes 11 to 13 and used for image formation. However, the quality of the transfer paper deteriorates as the number of times of use increases for one transfer paper. To do. For example, creases or wrinkles are formed, corners are folded, the surface is dirty or fluffed. This causes a paper jam in the copying machine or the image becomes rough.

である。Second Embodiment FIG. 5 shows a second embodiment of the present invention. In this embodiment, in the post-processing device 50, first, the number of marks on the transfer sheet is detected, and when the number of marks is N or more, the gate claw 57 is rotated to transfer the transfer sheet to the second tray. Halogen lamp 5
The mark sensor 54 and the stamper 55 are arranged at the transfer paper inlet so that the color erasing process is performed by No. 1, and the halogen lamp 51 is arranged between the gate claw 57 and the first tray 59. Along with this, in the CPU unit of the copying machine, the erasing processing program is slightly changed so as to perform the processing shown in FIG. Other configurations and processing operations are similar to those of the first embodiment.

第１実施例と同様である。In the second embodiment, the decoloring process of the transfer paper having the mark number N or more is not performed. -Third Embodiment- Fig. 7 shows a third embodiment of the present invention. This embodiment is the first
Further, the gate claw 57 of the second embodiment is omitted, and the function thereof is replaced by the sorter 40. The sorter 40 is the same as that shown in FIG. In the erasing mode, the CPU unit of the third embodiment sends the transfer paper having the mark number N or more to the lowermost tray of the sorter 40, and every time it reaches the set number of sheets. Switch to the upper tray and collect,
Transfer sheets having a mark number of less than N are sent to the uppermost tray of the sorter 40, and each time the set number of sheets is reached, the transfer sheet is switched to the lower tray and collected. Other configurations and processing operations are
This is similar to the first embodiment.
