Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a recording paper post-processing device, and more specifically, a method for stapling paper sheets such as paper sent from a recording device such as a copying machine or a printer. The present invention relates to a recording paper post-processing device that has a stapler that performs fastening and is provided with means for detecting the presence or absence of staples in the stapler.

[Prior Art] In conventional recording paper post-processing devices of this type, the staples used as staples for recording paper are electrically conductive, and the staples are not fully stapled until they are driven in. It was common to detect whether or not there was a staple in the stapler device.

[Opening point to be solved by the invention] However, with such a detection stage, the presence or absence of a staple is detected only when a stapling operation is performed, so the operator may not notice even though the stapler is missing a staple. A blank printing operation is performed to close the recording paper without it being loaded.
There was a problem in that the staples were loaded after that.

SUMMARY OF THE INVENTION An object of the present invention is to solve two consecutive problems, and to provide a removable recording paper post-processing device that can detect the absence of staples before the staples completely disappear. It's about doing.

[L Stage for Solving Problems] That is, the present invention provides a recording paper post-processing device equipped with a stapler that staples recording paper sent out from a recording device with staples. The present invention is characterized by having a first storage stage for storing staples, and an L stage for detecting the absence of staples before it becomes completely normal.

[Function] In the recording paper post-processing device configured as described above, when the cartridge in which the staples are stored is mounted on the stapler, and the amount of staples remaining in the cartridge becomes less than a predetermined amount, the optical detection P5 is activated. This state is detected by the tray, and the user can be warned of the state 7g before it becomes unstable, thereby eliminating wasteful empty binding operations of the recording paper.
