Description

  The present invention relates to a punching tool having two functions for making a hole in a document and binding the document.

Conventionally, when distributing a document composed of multiple sheets, the document is bound with metal staples in advance using a binding tool generally called a stapler so that the document is not separated. Later, using a punch called a punch, a pair of binding holes were made on one side of the document and bound to a file. However, in the above method, two operations of binding a document with a binding tool and a punching operation with a punching tool are necessary, and the binding tool and the punching tool must be prepared by the side, which is troublesome. There is also a problem that the work space on the desk becomes narrow.
As a method for solving this problem, there is a punching and binding tool formed by integrally assembling a binding tool using a conventional metal staple and a punching tool (see, for example, Patent Document 1). This is very convenient because it can be drilled and bound with a single tool.
On the other hand, as a document binding tool, without using staples, after folding a paper tongue piece formed by cutting out a part of the document to be bound, the end is passed through a slit opened in the same document, and the document is bound. There is something like this (see, for example, Patent Document 2).
With such a binding tool, there is no need for staples, so there is no need for staples to be lost and binding becomes impossible, and there is no need for a staple magazine for storing staples, so it is lightweight and can be made compact. There are benefits.
Further, a sealing port is provided on one side to insert the document when sealing (binding) the document, and a part of the document to be sealed is cut out into a substantially U shape on the sealing port side. A binding tool provided with a plurality of sealing mechanisms has also been proposed in which a mold part is formed, the U-shaped part is bent, and the leading end is inserted and removed from a groove formed in the same document (for example, Patent Documents). 3).
With such a binding tool, the document is bound at a plurality of locations, so that the document can be bound more firmly.

However, since the conventional punching and binding tool described in Patent Document 1 is simply a combination of the punching tool and the binding tool, the whole becomes large and heavy, and when opening a binding hole, When binding documents, it was necessary to push down the paper binding handles separately, which was very unusable. In addition, since a conventional metal staple is used for the binding portion, a vertically long staple magazine for storing the staple is indispensable, and it is difficult to reduce the size.
Further, since the binding tool disclosed in Patent Document 2 only binds one place of a document, when binding the document to a file, it is necessary to make a hole using a separate punching tool, which is inconvenient to use. It was.
Further, the binding tool disclosed in the above-mentioned Patent Document 3 simply allows a plurality of locations of the document to be bound by a single pushing operation. When binding, it was necessary to open a hole using a separate drilling tool, which was unusable.
