Abstract
A punching apparatus capable of performing update work for updating maintenance information, irrespective of whether or not a punch die is mounted. A puncher includes a punching unit that punches a sheet using an exchangeable punch die provided with a die memory, and a CPU that detects mounting of a punch die in the punching unit. The CPU receives an update request requesting update of maintenance information stored in the die memory of the punch die. If mounting of the punch die is detected, when the update request designating the punch die is received, the CPU updates the maintenance information of the punch die based on the update request. If mounting of the punch die is not detected, the CPU updates the maintenance information of the punch die when mounting of the punch die is detected.
