Abstract

To provide a sheet processing apparatus and an electromagnetic locking method of a stacking device for unlocking a stacking device cover when a door of the sheet processing apparatus is closed, shortening the power supply time of an electromagnetic lock, suppressing power consumption, and displaying permission of access to the stacking device. When a condition of unlocking a stacking portion and opening of the door is detected, the electromagnetic lock is held in an unlocking state and a cover opening-closing permission display lamp is turned on. After end of an operation by an operator, if the closing of the door is detected by a door detection device, the electromagnetic lock of the stacking device is turned off and the lamp is turned off. As a result, an unlocking condition is held when no power is supplied to a solenoid. Further, when a condition of locking the stacking portion occurs, if the opening of the door is detected, the electromagnetic lock is turned on, and the lamp is turned off, and after the operation ends, if the closing of the door is detected, the electromagnetic lock is turned off and the lamp is turned off.
