In consideration of easiness of movement, that is, reduction of the moving load, a device having a relatively small storage capacity is usually provided. However, in a small-capacity waste storage box, a large amount of waste that cannot be stored overflows from the storage box, and may enter a sensor, a driving mechanism, or the like disposed in the vicinity and cause a malfunction. Maintenance work is required.

According to the present invention, it is possible to store debris generated due to paper processing applied to an arbitrary position without leakage, increase the storage capacity of debris, and reduce maintenance work. An object of the present invention is to provide a sheet processing apparatus for a sorter.

[0005]

In order to achieve the above object, the present invention provides a sheet processing apparatus for a sorter for performing a sheet process on transfer paper on which formed images are transferred, sequentially sorted into bins, and discharged. Paper processing means for performing predetermined paper processing on an arbitrary position of the transfer paper discharged to the bin; moving means for reciprocating the paper processing means in the width direction of the bin; and a lower rear portion of the paper processing means. A dust storage member which is disposed and whose upper part is open at least over the reciprocating range of the paper processing means, and which is provided in the paper processing means and which generates debris accompanying paper processing at an upper opening of the waste storage member. A guiding member, which is formed to have a U-shaped cross-section that is inclined downward from the lower part of the paper processing means in the paper processing means toward the above-mentioned waste storage member and opens upward. Is shall.

[0006]

According to the present invention, when paper processing is performed on a predetermined position of the transfer paper, debris is generated along with the paper processing, and the debris is received by the guide member. To the upper position of the waste storage member at the lower rear. Then, the waste is stored by falling into the waste storage member from the opening.
