Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a perforator used for punching holes at regular intervals in a sheet of paper.

(Prior Art) Conventionally, in order to bind sheets of paper into binders or files, punches have been used to punch holes at regular intervals along one edge of sheets of paper.

The conventional perforator, as shown in Fig. 7,
The base of the press rod b is pivoted to the rear end of the base a, and is normally kept in the raised position shown in the figure by a spring, and the edge of the paper is inserted into the paper insertion part c provided at the rear of the base a. By pressing down the press rod b, the punch (not shown) is pressed down by the base of the press rod b, and the paper is perforated.

(Problem to be solved by the invention) In the above-mentioned conventional perforator, when not in use, the press rod b is placed in a form that protrudes diagonally in the height direction, so it is extremely bulky, and the press rod b does not move forward or backward. A predetermined length is required because the hole is to be drilled using a screw, and the area of the base a also increases, making the overall structure large, making it difficult to store in a bag, pocket, etc. It was extremely unsuitable for carrying around.

In view of this, the present invention has been developed in order to solve the problems of the above-mentioned prior art.When not in use, it becomes flat and can be easily stored in a bag or clothing pocket.When in use, it becomes a shape suitable for piercing. The purpose of this invention is to provide an extremely small punching device that can punch holes in paper anytime and anywhere.
