SHEET POST-PROCESSING DEVICE AND IMAGE FORMING DEVICE PROVIDED WITH THE SHEET POST-PROCESSING DEVICE

摘要

A sheet post-processing device includes a conveying section that conveys a paper sheet; a punch section that punches punch holes in the paper sheet conveyed by the conveying section; a stacker section that stores the paper sheet in which the punch holes are punched by the punch section; a binding section that binds a paper sheet bundle stored in the stacker section with a binding member; and a controller that controls the above sections. The controller selectively performs a ring binding mode and a direct binding mode. The ring binding mode is a mode in which punch holes are punched in the paper sheet by the punch section and then the binding member is made to penetrate the punch holes for binding. The direct binding mode is a mode in which the binding member is directly driven into the paper sheet bundle without punching the punch holes in the sheet.

主权项

1. A sheet post-processing device that punches punch holes in a paper sheet and binds a stored paper sheet bundle, comprising:
a conveying section that conveys the paper sheet; a punch section that punches punch holes in the paper sheet conveyed by the conveying section; a stacker section that stores the paper sheet in which the punch holes are punched by the punch section; a binding section that binds the paper sheet bundle stored in the stacker section with a binding member; and a controller that controls the above sections, wherein the controller selectively performs a ring binding mode and a direct binding mode, the ring binding mode being a mode in which punch holes are punched in the paper sheet by the punch section and then the binding member is made to penetrate the punch holes for binding, the direct binding mode being a mode in which the binding member is directly driven into the paper sheet bundle without punching the punch holes in the sheet.
