Abstract

A sheet processing apparatus comprising: a conveying unit configured to have a roller that conveys a sheet in a conveyance direction; a first detecting device disposed downstream of the conveying unit in the conveyance direction; a second detecting device disposed downstream of the first detecting device in the conveyance direction; a boring unit configured to have a punch that performs boring in the sheet; and a control unit is used. The first detecting device and the second detecting device each detect passage of a leading edge of the sheet being conveyed. The control unit calculates an actual conveyance speed of the sheet on the basis of detection results of the first detecting device and the second detecting device, and controls rotation of the roller, on the basis of the actual conveyance speed, so that the sheet is conveyed at a predetermined target speed.
