Similar to the first embodiment, the binding processing device 4 according to the present embodiment is configured such that the needle binding unit 420 is arranged on the front side of the device and the needle-less binding unit 430 is arranged on the back side of the device.

Further, the binding processing device 4 according to the present embodiment is configured to convey the sheet based on the device front reference or the device center reference. This is because when the sheet is conveyed based on the back of the device, if the sheet is clogged, it becomes difficult to remove the clogged sheet. In particular, when a small-sized sheet is clogged, the removal work becomes more difficult.

Therefore, in the binding processing device 4 according to the present embodiment, the needle-less binding unit 430 arranged on the back side of the device is mainly used for binding processing of both the minimum size sheet and the maximum size sheet. It is necessary to move in the scanning direction.

Further, in the binding processing device 4 according to the present embodiment, the needle-free binding unit 430 is tilted with respect to the sheet, for example, in a state of being tilted by 45 degrees in order to strengthen the binding force. Is configured to do.

Further, in the binding processing device 4 according to the present embodiment, the width in the main scanning direction of the sheet loading plate 440 is smaller than the width in the main scanning direction of the maximum size sheet and larger than the width in the main scanning direction of the smallest size sheet. It is configured.

Therefore, in the needle-less binding unit 430, when binding the smallest size sheet, the back side of the binding opening may collide with the corner of the sheet loading plate 440 during the movement from the home position to the binding position.

Therefore, in order to avoid such a collision, it is conceivable to increase the depth of the binding opening of the needle-less binding unit 430. However, since the needle-less binding unit 430 needs to crimp the sheet with a very large force, for example, a very large force of 200 N, the distance between the fulcrum and the point of action, that is, the depth of the binding opening is as short as possible. Need to be done.

Therefore, as shown in FIG. 25, in the binding processing device 4 according to the present embodiment, the sheet loading plate 440 is configured with a notch in the range in which the needle-less binding unit 430 moves. As a result, even when the needle-less binding unit 430 binds the smallest size sheet, the back side of the binding opening and the corner of the sheet loading plate 440 collide with each other during the movement from the home position to the binding position. It is possible to move to the binding position without any problem.

However, when the seat loading plate 440 is configured in this way, as shown in FIG. 26, the sheet bundle A may hang down at the notched portion of the seat loading plate 440.

Then, when the binding processing device 4 attempts to move the needle-free binding unit 430 from the home position to the binding position in such a state, the binding port of the needle-free binding unit 430 and the end of the sheet bundle A in the main scanning direction Will collide with. Therefore, in such a case, the binding processing device 4 cannot properly perform the binding processing by the needle-less binding unit 430.

Therefore, as shown in FIG. 25, the binding processing device 4 according to the present embodiment moves together with the needle-less binding unit 430 so that the sheet bundle A does not hang down at the notch portion of the sheet loading plate 440. It is configured to include a moving sheet support plate 441 that supports A from the binding direction. That is, in the present embodiment, the moving seat support plate 441 functions as a seat support portion.

When the binding processing device 4 according to the present embodiment is configured in this way, as shown in FIG. 27, the back side of the binding opening of the needle-less binding unit 430 and the corner of the sheet loading plate 440 collide with each other. It is possible to accept the sheet bundle A in the binding port of the needle-less binding unit 430.

In the present embodiment, the binding processing device 4 in which the moving sheet support plate 441 is fixed to the needle-less binding unit 430 has been described. In addition, as shown in FIG. 28, the binding processing device 4 according to the present embodiment is configured such that the moving sheet support plate 441 and the needle-less binding unit 430 move individually but in conjunction with each other. Is also good.

In addition, the binding processing device 4 according to the present embodiment includes a drive unit for driving the moving sheet support plate 441, and the moving sheet support plate 441 and the needle-less binding unit 430 move individually, but are interlocked with each other. It may be configured to move.

Further, in the present embodiment, the binding processing device 4 in which the needle binding unit 420 is arranged on the front side of the device and the needle-less binding unit 430 is arranged on the back side of the device has been described. In addition, the binding processing device 4 according to the present embodiment may be a case where the needle binding unit 420 is arranged on the back side of the device and the needle-less binding unit 430 is arranged on the front side of the device.
