A punching apparatus comprises a punch for punching holes in a sheet, a cam member for reciprocally moving the punch in a punching direction, a motor for moving the cam member, a pulse generator for generating pulses that are synchronized with the driving of the motor, and a control unit for applying a brake to the motor to stop the cam member upon counting the pulses of a predetermined number from the pulse generator after the cam member moved by the driving of the motor passes through a reference position, in which the control unit, in case of performing an adjust mode that adjusts a timing of the braking of the motor, performs first driving processing for stopping the driving of the motor upon counting the pulses of the predetermined number after the moved cam member passes through the reference position, performs second driving processing for driving the motor by normal rotation or reverse rotation and counting the pulses until the cam member reaches a predetermined position, and determines the predetermined number based on the pulses counted in the second driving processing.
