The above-mentioned display may be performed each time the copy sheets are being loaded into the tray one by one, or may be displayed after a predetermined number of copies have been placed on the tray. (In the latter case, it may be sufficient to simply detect the overall alignment of the sheets after a predetermined number of copies have been deposited on the tray. The operator should stop the copying machine, manually align the copies, and then press the print key 7 again to resume copying. It is also possible to automatically stop the operation of the copying machine based on the output of the detection means.If the display is to be displayed after all copy paper has been delivered, the copy paper In addition, the acceptable degree of alignment of the copy sheets is usually not constant depending on the operator's wishes, and the extent to which the copy image on the photocopy presentation will be formed may not be the same. There are cases in which it is not a problem, and cases in which the position of the copied image on the copy paper is strict and must be maintained; in the former case, it is not a problem even if the copy paper on the tray is aligned. In the latter case, the opposite is true.Therefore, when the alignment status is displayed and the operator judges that there is no problem with the hole, it is sufficient to continue the seven-fold copying operation, or it is judged that there is no problem. It is a good idea to readjust the copy paper every 1 time.Alignment condition w G) If the digital display is as shown in K indicator 1, the operator can reliably check the degree of zn, t, and t'. The decision as to whether there is a problem or not will be made immediately.

At the same time, when the copy paper 2 is in an irregular state and n exceeds a predetermined amount, the output of the detection means controls a driving means, in this example a stepping motor, which operates the side fences 5 and 6, and causes the side fences to reciprocate. It is also possible to rearrange the copy sheets 2 by increasing the frequency of . In this case, when the copy paper 2 is being conveyed to the tray 3 one after another, the copying operation may be interrupted, or the side fence operation frequency may be increased and the alignment may be performed without interruption. Alternatively, after a predetermined number of copies have been carried in, the side fence may be operated additionally once or multiple times to realign the copies. The effect of aligning the copy sheets may be enhanced by lowering or combing the stroke, and the copy sheets that have become uneven may be rearranged efficiently.

As the detection means for detecting the alignment of the copy sheets, other than the IJ configuration shown in FIGS. 2 to 4 may be adopted as appropriate. For example, if the copy sheets on the tray 3 are uneven, this will act as a load on the side fence.
6 cannot be moved to the 1 position shown by the dashed line in Figure 2, but considering this point, both side fences 5 and 6 are closest to each other and the position is 1, or the position at this time. It is also possible to know the alignment condition r of copy sheets by detecting the distance r between both side fences. Figure 5 shows an example,
Align the copy paper 2 in the specified position as shown by the dashed line.
Sometimes the side fence 6 is the other side fence 5.
(not shown in FIG. 5), if the copy paper 2 becomes uneven as shown by the two-dot chain line, the side fence 6 will touch the other side fence 5. The closest final position is the position indicated by the chain double-dashed line. Therefore, 118 detection means 118 are provided, each consisting of a support type light source 29 so as to be movable integrally with the side fence 6, and a plurality of light receiving elements 30 to 35 arranged above the light source 29 in the width direction B. In this way, when the side fence 6 reaches the final position indicated by the one-dot chain line, the light from the 15 light source 2'5 enters the light receiving element 34. When the light from the light source 29 enters the light receiving element 32, the light from the light source 29 enters the light receiving element 32. Therefore, it is assumed that the light from the light source 29 enters the light receiving element 3-4 when the side fence 6 reaches the final position, and it depends on which light receiving element the light from the light source 29 actually enters. You can check the alignment of the copy paper.

The stepping motor that drives the side fences 5 and 6 is inputted to the motor by a predetermined number of pulses according to the width size of the copy paper, and the angle is set according to the number of pulses. It is supposed to rotate, but the copy paper is not aligned.
Therefore, if the side fence cannot operate at the final position 1 shown by the dashed line in Fig. 2 or Fig. 5, the drive sprocket 9 (Fig. 1) will rotate by an angle smaller than the rotation angle shown in Fig. 2. I will do it. Focusing on this point, as schematically shown in FIG.
A detection means 218 is formed by a large number of through holes 37 formed at equal intervals along the circumferential direction of the disk 3G, a light source 38 and a photoelectric sensor having 5 light receiving elements 39' located opposite each other. Can be configured.

In this case, each element is positioned so that the light from the light source 38 passes through one through hole 37 and enters the light receiving element 39. Therefore, the disk 36 rotates, and each through hole 37
When 9 is located between the light source 38 and the light receiving element 39, the light from the light source 38 enters the light receiving element 39, so the rotation of the disc 36, that is, the driving sprocket 9, depends on the number of times that 9 enters the light receiving element 39. The operating amount r of the side fence can be known.
