Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to a stapler for binding multiple pieces of paper, cardboard, thin plywood, etc. Specifically, it is a stapler for binding documents, memos, etc. with a staple. To provide a stapler that can be temporarily fixed to a mount, cardboard, etc. and easily remove slips, etc. without removing the staples.

[Conventional technology]

Staplers are widely used, for example, to bundle a plurality of sheets of paper into a single stack, or to fasten the flaps of paper boxes or cardboard boxes. The binding needle used in such a stapler is a wire-shaped needle that has a support part and a pair of parallel binding feet bent approximately perpendicularly from both ends of the support part, taking into consideration the ability to penetrate the items to be stapled. It is composed of linear bodies.

In this way, binding staples can easily bind multiple sheets of paper together, so they can be used not only for permanent binding, but also for temporary binding and eventually binding other sheets together. It's being used.
In such cases, the temporarily bound staple must be removed, and if the stack is thick, a thin piece of metal may be inserted between the top sheet and the staple support to pull the support up. If you do this, you can open the binding foot and remove the staple, but if the paper is thin, you can insert a metal piece to remove not only the topmost paper, but also the binding foot.
There is a possibility that the paper underneath may be torn by the metal piece. Furthermore, there is a possibility that the hole through which the binding foot passes will expand as the support is pulled up. Therefore, when carefully removing the binding staple, it is necessary to return the bent binding foot to a straight line again, and then carefully pull it out from the support section.

[The problem that the idea aims to solve]

As a result, the staples are bent without being guided by the bending table member, making it easy to bind items by simply applying the stapler to the desired location on the top of the article and pushing out the staples with the handle member. . This is particularly suitable for temporarily attaching destination tags to cardboard boxes. However, its structure is complex, making it difficult to mass produce, and it has the disadvantage that it cannot be provided at a low price.

Therefore, the inventor of the present invention proposed a stapler for a stapler that can be temporarily fixed in Utility Application No. 1983-47910 (Utility Model Application No. 1-150206) filed on April 9, 1988. This temporary binding needle is different from conventional binding needles,
A binding foot is provided only at one end of the support part of the binding staple, and after documents, etc. are bound with this temporary binding staple, the topmost document is attached in the direction in which the support part extends and the binding foot is present. It can be easily removed by sliding it in the direction.

The purpose of this invention is to provide a stapler that is most suitable for the temporary fixing staples proposed in the earlier invention and has a simple structure.

[Means to solve the problem]

The stapler of this invention consists of a supporting part and one end bent at a substantially right angle from one end of the supporting part.
A stapler for temporary stapling needles having book binding foot parts, a staple case having a needle ejection opening for ejecting the temporary stapling staples on the lower surface of the tip, and a binding foot of the temporary stapling staples ejected from the staple ejection opening. It has a base provided with a needle receiving part for bending the part toward the supporting part, and a handle whose rear end is rotatably attached to the base together with the rear end of the needle case. A needle rest having an upper surface that supports the support part of the temporary stitching needle, and a side part that is spaced apart from one side of the needle case and that forms a passage for the binding foot, and a needle rest that slides on the needle rest. The present invention is characterized in that it has a movably attached needle pusher, and has a needle drive plate on the lower surface of the hand for discharging the temporary stapling needle located in the lowered hour hand discharge opening from the needle discharge opening. .

[Effect]

With the structure described above, when a document or memo is placed on the needle holder and the handle is lowered, the lower end of the needle striking plate will come into contact with the temporary stapling needle support located on the needle discharge exit side. and lower the temporary stitching needle from the needle discharge outlet. This allows the binding foot of the temporary stitching needle to
It passes through the type, etc., reaches the needle receiving part of the base, and the binding foot part is bent toward the support part side, and can be latched to the lower surface of the document etc. for temporary fixation. If you want to remove the top document, etc., you can easily remove only the top document by shifting it parallel to the support part of the temporary staple and toward the binding foot. Additionally, if the edges of the documents, etc. are shifted from directly below the needle receiver, the binding feet of the temporary stitching needles will reach the back side of the documents, etc. from these edges without penetrating the documents, etc. It can also be temporarily fixed with a clip.
