Claim Text:
1. A post-processing device comprising: a stapling unit that performs stapling on a sheet bundle with a driving force caused by a rotation of a motor; a power supply unit that supplies power only to the motor; a sheet bundle detector that detects presence or absence of the sheet bundle which is inserted into the stapling unit; and a stapling time storage unit that stores an execution time of one session of the stapling, wherein the power supply unit maintains a first output voltage that is predetermined and is required for an operation of the motor and a second output voltage that is lower than the first output voltage in such a manner as to be selectable via a switching element, outputs the first output voltage to the motor based on a detection result of the sheet bundle detector, maintains the second output voltage after an elapse of a predetermined time which is stored in the stapling time storage unit, and stops supplying the power to the motor.
