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.

First claim

What is claimed is:

1. A punching apparatus comprising:
a puncher configured to perform a punching process on a sheet using an exchangeable punch die provided with a first memory for storing maintenance information which is information concerning maintenance of the exchangeable punch die;
a detector configured to detect mounting of an exchangeable punch die in said puncher;
a second memory configured to store the maintenance information stored in the first memory of the exchangeable punch die;
a receiver configured to receive an update request requesting update of the maintenance information stored in the first memory of a designated exchangeable punch die; and
a controller configured to, in a case where an update request requesting update of the maintenance information stored in the first memory of the designated exchangeable punch die is received by said receiver, if mounting of the designated exchangeable punch die has been detected by said detector, update the maintenance information stored in the first memory of the designated exchangeable punch die, based on the update request, and if mounting of the designated exchangeable punch die has not been detected by said detector, store, in the second memory, first information indicating that the update of the maintenance information stored in the first memory of the designated exchangeable punch die is required, without updating the maintenance information stored in the first memory of the designated exchangeable punch die,
wherein in a case where the mounting of the designated exchangeable punch die has been detected by said detector and the first information is stored in the second memory, the controller updates the maintenance information stored in the first memory of the designated exchangeable punch die without the update request being received again by the receiver.

2. The punching apparatus according to claim 1 , wherein designation of an exchangeable punch die is performed by designating identification information for identifying each of exchangeable punch dies, and in each of first memories of the respective exchangeable punch dies, the maintenance information and the identification information are stored in a manner associated with each other.

3. The punching apparatus according to claim 2 , wherein the identification information is number information associated with each of the exchangeable punch dies.

4. The punching apparatus according to claim 1 , wherein the maintenance information is information concerning a time at which maintenance is performed for the designated exchangeable punch die.

5. The punching apparatus according to claim 1 , wherein the maintenance information is information concerning the number of times the punching process has been performed using the designated exchangeable punch die from a time at which the maintenance is performed for the designated exchangeable punch die.

6. The punching apparatus according to claim 1 , wherein the maintenance is to perform lubrication for the exchangeable punch die.

7. The punching apparatus according to claim 1 , wherein the controller deletes the first information stored in the second memory when updating the maintenance information stored in the first memory of the designated exchangeable punch die.

8. The punching apparatus according to claim 1 , wherein the controller updates the maintenance information stored in the first memory of the designated exchangeable punch die and the maintenance information stored in the second memory.

9. A punching system comprising:
an image forming section configured to perform image formation on a sheet;
a puncher configured to perform a punching process on a sheet using an exchangeable punch die provided with a first memory for storing maintenance information which is information concerning maintenance of the exchangeable punch die;
a detector configured to detect mounting of an exchangeable punch die in said puncher;
a second memory configured to store the maintenance information stored in the first memory of the exchangeable punch die;
a console configured to input maintenance completion information indicating that maintenance of a designated exchangeable punch die is complete; and
a controller configured to, in a case where the maintenance completion information is input by said console, if mounting of the designated exchangeable punch die has been detected by said detector, update the maintenance information stored in the first memory of the designated exchangeable punch die, and if mounting of the designated exchangeable punch die has not been detected by said detector, store, in the second memory, first information indicating that the update of the maintenance information stored in the first memory of the designated exchangeable punch die is required, without updating the maintenance information stored in the first memory of the designated exchangeable punch die,
wherein in a case where the mounting of the designated exchangeable punch die has been detected by said detector and the first information is stored in the second memory, the controller updates the maintenance information stored in the first memory of the designated exchangeable punch die without the update request being input again by the console.

10. The punching system according to claim 9 , wherein the maintenance information is information concerning the number of times the punching process has been performed using the designated exchangeable punch die from a time at which the maintenance is performed for the designated exchangeable punch die.

11. The punching system according to claim 9 , wherein the maintenance is to perform lubrication for the exchangeable punch die.

12. The punching system according to claim 9 , wherein the controller deletes the first information stored in the second memory when updating the maintenance information stored in the first memory of the designated exchangeable punch die.

13. The punching system according to claim 9 , wherein the controller updates the maintenance information stored in the first memory of the designated exchangeable punch die and the maintenance information stored in the second memory.

14. The punching system according to claim 9 , wherein designation of an exchangeable punch die is performed by designating identification information for identifying each of exchangeable punch dies, and in each of first memories of the respective exchangeable punch dies, the maintenance information and the identification information are stored in a manner associated with each other.

15. The punching system according to claim 14 , wherein the identification information is number information associated with each of the exchangeable punch dies.

16. The punching system according to claim 9 , wherein the maintenance information is information concerning a time at which lubrication is performed for maintenance of each exchangeable punch die.
