Problems solved by technology

In this case, if the switch is repeatedly turned off and on every time a sheet is fed, the life of the switch will be shortened, and depending on the situation, it may be shorter than the life of the stapler.

Embodiment Construction

[0015] Next, the sheet processing apparatus of the present invention will be described with reference to the drawings.

[0016] First, refer to figure 1 , the overall configuration of the sheet processing apparatus 1 will be described. figure 1 It is a front view of the sheet processing apparatus 1 . Will figure 1 The front side of the paper surface of , is taken as the front side of the sheet processing apparatus 1 . L and R in each figure indicate the left side and the right side of the sheet processing apparatus 1 , respectively. The sheet processing apparatus 1 is arranged adjacent to, for example, an image forming apparatus that forms an image by an inkjet system, and performs post-processing on a stack of sheets on which images have been formed by the image forming apparatus.

[0017] The sheet processing apparatus 1 has a substantially rectangular parallelepiped main body 3 and legs 5 supporting the main body 3 . In the main body portion 3, a receiving port 7 is fo...

Abstract

The invention provides a sheet processing device. The sheet processing device includes a processing tray, a processing device, a discharge port, a discharge rollers pair, a supporting arm and an interlock mechanism. The discharge rollers pair has a lower roller and an upper roller. The supporting arm supports the upper roller and is turnable between a first position where the upper roller comes into contact with the sheet and a second position where the upper roller separates upwardly from the sheet. The interlock mechanism includes an actuator, a switch and a switch moving mechanism. The actuator is turned with an upwardly turning of the supporting arm. The switch detects the actuator to detect that the supporting arm is turned to the second position. The switch moving mechanism moves theswitch to a switch non-detective position when the processing is not performed and moves the switch to a switch detective position when the processing is performed.

Description

technical field [0001] The present invention relates to a sheet processing apparatus that performs processing such as binding processing including binding a stack of sheets with staples. Background technique [0002] In a sheet processing apparatus that performs bookbinding processing or the like, there is a processing tray for stacking sheets switched back at a discharge port to form a stack of sheets to be processed. In consideration of the safety of a sheet processing apparatus that performs stapling processing, a foreign object detection device that detects objects located above a bin tray (processing tray) may be provided. This foreign object detection device has an operation handle for foreign object detection disposed above the box pallet so as to be able to advance and retreat. When a foreign object is inserted above the box tray, the foreign object detection handle cannot be moved forward, and the foreign object detection switch cannot be switched from OFF to ON, t...
