Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a stapler that can be made into a card shape that is thinner than the width of the staples.

(Prior Art and its Problems) Recently, there has been a trend toward smaller products in various fields, and there is a desire for some products to be smaller in stationery as well. In the past, attempts have been made to make staplers smaller. For example, JP-A-61-
As shown in No. 146480, etc., it is known that the stapler is shortened in the longitudinal direction to achieve miniaturization. One method for this purpose is to use a magnet as a means for supplying the staple to the punching part within the stapler (such as Utility Model Application No. 60-7978). Although these techniques made it possible to reduce the longitudinal dimension of the stapler, it was not possible to reduce the width dimension because the staples were fired in a direction perpendicular to the longitudinal direction. , it has become inconvenient for mobile phones to replace conventional ones.

In addition, there is a technology disclosed in Japanese Utility Model Application No. 60-22278 that allows the staple to be driven in a direction parallel to the longitudinal direction, but since the driver rotates around a pivot point, the staple is clinched. This causes the staple to not be able to be ejected accurately, causing the staple to jam.

(Technical problem of the invention) The present invention was developed in view of the above circumstances, and it is possible to make the width dimension of the stapler smaller than the width dimension of the binding needle, and it is possible to reduce the occurrence of jams etc. Our goal is to provide a mini stapler that can be spelled out accurately.

(Means for Solving the Problems) In order to achieve the above-mentioned problems, the stapler according to the present invention consists of a stapler body and a stapler cartridge that accommodates staples configured separately from the stapler body, and also meets the following requirements. It is characterized by being equipped.

(a) A binding paper insertion groove is formed in one side end of the stapler body, and a clincher is formed along the longitudinal direction on one opposing groove wall surface of the insertion groove; A driver member guide groove is formed in the other groove wall surface facing the clincher.

(b) In the driver member guide groove, a driver member for driving out the staples is provided so as to be biased in a direction opposite to the clincher so as to be able to move linearly, and the tip of the biased driver member and the other groove wall surface. A accommodating portion for accommodating the staple cartridge is formed with an opening in a direction perpendicular to the guide groove.

(c) The staple cartridge is provided with a driver member through-hole that aligns with the guide groove when installed in the storage section, and a staple supply means for supplying the staple staples inside toward the guide groove. being given.

(d) Positioning means is formed between the stapler main body and the staple cartridge to align and position the driver member through-hole with the guide groove of the driver member.

(e) An operation operation section facing the outside of the stapler body and operating the driver member is provided.

(Operations and Effects of the Invention) As described above, the stapler according to the present invention has a stapler main body and a staple cartridge as separate bodies, the staple cartridge is detachable from the stapler body, and the clincher is inserted into the groove in the stapler body. Since the stapler body is formed in the longitudinal direction of the groove wall surface and the driver member is also provided correspondingly, the stapler body can be formed into a thin card shape.

When using the stapler configured as described above, the staple cartridge is housed in the storage section of the stapler main body, and after it is installed in a predetermined position by the positioning means, the binding paper is inserted into the insertion groove, and the operation operation section When operated, when the driver member moves linearly along the guide groove, it engages with the stapler in the stapler cartridge in the accommodating portion, separates it from other staplers, and drives it out. Since the binding needle is driven from the insertion groove toward the clincher, after passing through the binding paper, it engages with the clincher and is bent, thereby binding the binding paper. After binding, by releasing the actuating portion, the driver member returns to its original position since it is biased in the direction opposite to the clincher.

Since the driver member is provided to move linearly within the guide groove, the same pressing force is applied to the needle legs on both sides of the binding needle during binding. Therefore, good spelling can be obtained.
