SUPPORT MECHANISM FOR PROCESSING UNIT IN SHEET PROCESSING DEVICE

摘要

The present invention is to provide a processing unit which can move smoothly to accurate position in a proper posture. The processing unit is provided with a support mechanism that supports a processing unit 26 so as to allow the processing unit 26 to be moved to a sheet processing position (processing tray) 24. The support mechanism includes the processing unit 26 and first and second support portions 50 and 55 that support the processing unit 26. The first and second support portions 50 and 55 apply, to different positions (j and k) of the processing unit 26 which are spaced from each other, a support force Fa acting from below to above (in a direction opposite to a gravity acting direction) and a support force Fb acting from above to below (in a direction same as the gravity acting direction), respectively.

1. A support mechanism that supports a processing unit provided in a sheet processing device so as to allow the processing unit to be moved to a processing section, the mechanism comprising:
the processing unit, a first support portion that supports the processing unit and applies a support force acting from below to above to the processing unit; and a second support portion that supports the processing unit and applies a support force acting from above to below to the processing unit, wherein a position where the first support portion applies a support force acting from below to above is different from a position where the second support portion applies a support force acting from above to below.
