2. Description of the Related Art Conventionally, as a paper punching apparatus for punching this kind of paper, Japanese Patent Application Laid-Open No. Hei 9-136762 has been disclosed.
JP, JP-A-10-7307 and JP-A-11-107
There is one disclosed in, for example, Japanese Patent No. 263528. These JP-A-9-136762 and JP-A-10-7
No. 307 and Japanese Patent Application Laid-Open No. H11-263528 disclose a paper punching device that can perform two or more types of punching processes, such as a two-hole punching process and a three-hole punching process. There has been known a sheet punching apparatus which selectively uses the punching means to perform a punching process on a sheet such as a copy sheet.

As a sheet punching apparatus for punching sheets such as the above-mentioned copy sheets, Japanese Patent Application Laid-Open No. Hei 9-151 discloses
As disclosed in Japanese Patent No. 025, a sheet processing apparatus in which two or more types of punch units are exchangeably mounted, and a desired punching process can be performed by the mounted punch units has already been proposed.

Further, as a technique relating to the detection of the fullness of punch debris generated when a punching process is performed by the paper punching apparatus, as disclosed in Japanese Patent Application Laid-Open No. Hei 7-137926, It is generally known to have a dust receiver for receiving the punch dust and a counting means for counting the number of punches, and to detect the fullness of the dust receiver by the count value of the punch number counting means. ing.

[0005]

However, the prior art described above has the following problems. That is, in the case of the image forming system having a punch function disclosed in Japanese Patent Application Laid-Open No. 7-137926, there is provided a counting means for counting the number of punches, and the detection of the fullness of the dust receiver is performed by the counting means. This is configured to be performed by numerical values. JP-A-7-1379
Japanese Patent Application Laid-Open No. Hei 9-13676 discloses a technique disclosed in
No. 2, JP-A-10-7307 and JP-A-11-11
As disclosed in Japanese Unexamined Patent Application Publication No. 263528/1993 and Japanese Patent Application Laid-Open No. 9-1551025, there is provided a punching means capable of performing two or more types of punching processes, or two or more types of punching processes are performed by replacing a punch unit. When applied to a paper punching device that enables the punching, if the device can punch two or three holes, all punching processes can be performed as quickly as possible with a punch fuller, like a three-hole punching process. As the punching process, the number of operations of the punching process is counted, and when the count value of the number of operations of the punching process reaches a predetermined value, setting is made so as to detect the fullness of the punching waste, and the fullness of the punching waste is detected. It is configured to display.

However, the number of times of punching operation when punch dust becomes full depends on the number of punched holes in punching, the diameter of punched holes, the thickness of paper, and the like. When the number of punching operations to reach full punch dust is set based on the maximum number of holes in which punch dust is full and punch processing of thick paper etc.
In spite of the fact that there is still room in the punch waste collection box, there is a problem that a full punch waste is detected.

Further, the image forming system having a punch function disclosed in Japanese Patent Application Laid-Open No. 7-137926 is configured to display the fullness of the punch dust when fullness is detected based on the number of punching operations. .

Since it is built in the apparatus and covered by the cover, it is difficult to know how many punch units are mounted on the post-processing apparatus without performing a punching operation. Therefore, in a device in which a plurality of types of punch units can be attached to and detached from one post-processing device, there is a problem that a punch process different from a desired punch process may be erroneously performed. Was. In particular, if a number of post-processing devices are arranged in close proximity and each of the post-processing devices is equipped with a different punch unit, a punch process different from a desired punch process is erroneously executed. The fear becomes very noticeable.
In addition, the above problem also occurs in a punch unit having a different hole diameter for punching, in addition to an apparatus capable of performing a plurality of punching processes having different numbers of holes for punching.

Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, and a first object of the present invention is to provide a punching apparatus capable of performing a plurality of different types of punching. In, according to the type of punch processing that is actually performed, the timing at which the punch dust is full is detected, and the maximum use of the punch dust collection container is performed.
It is an object of the present invention to provide a punch processing apparatus capable of preventing the operability from being unnecessarily displayed by displaying the detection of the fullness of punch waste, and an image forming apparatus including the punch processing apparatus.
