Abstract

The invention provides a sheet post-processing apparatus, and the apparatus can achieve the miniaturization of a drive motor and can prevent the clamping of a barrier below a discharge tray. Accordingto one embodiment, a sheet post-processing apparatus has a sheet discharge tray, a drive motor, a power transmission breaker, a first power transmitter, a second power transmitter, and a load reducer. The sheet discharge tray stacks sheets. The drive motor raises and lowers the sheet discharge tray. The power transmission breaker can cut off power transmission from the drive motor to the sheet discharge tray when an upward external force is applied to the sheet discharge tray. The load reducer provides a reverse load to the sheet discharge tray in a reverse direction to the load generated onthe sheet discharge tray due to stacking of the sheets. The load reducer is connected to the first power transmitter.

Description

[0001] This application is based on Japanese patent application 2017-120898 (application date June 20, 2017) and enjoys its priority rights. This application refers to the priority application and includes all the content of the priority application. Technical field [0002] The embodiment of the present invention relates to a sheet post-processing device. Background technique [0003] There is known a sheet post-processing device for performing post-processing on a sheet conveyed from an image forming apparatus (for example, an MFP (Multifunction Digital Complex Machine)). The sheet post-processing apparatus includes a processing section that performs binding or sorting of the conveyed sheets. The sheet post-processing device further includes a discharge tray and a drive motor. The discharge tray can be loaded with sheets discharged from the processing unit. The drive motor raises and lowers the discharge tray. The discharge tray is driven up and down in a state where a large...
