ABSTRACT:
A sheet processing apparatus includes a sheet-table unit, a sheet-separating unit disposed at a downstream end of the sheet-table unit along a convey direction of the sheets, a convey unit arranged at a downstream end of sheet-separating unit, a discharge unit located at a downstream end of the convey unit, an sheet processing unit placed between the convey unit and the discharge unit, a speed sensor arranged at an upstream end of the sheet-separating unit for detecting a movement of each sheet for forming a sheet interval between two adjacent sheets, and an edge sensor located between the sheet-separating unit and the sheet processing unit. The edge sensor detects a front edge and a rear edge of each sheet passing therethrough, and sends corresponding control signals to a system controller which delays a predetermined time according to the control signals to control the sheet processing unit to start and stop processing.
