Abstract

PROBLEM TO BE SOLVED: To provide a two-hole punching tool short in the depth of a punching tool base, and having large punching capacity.SOLUTION: The punching tool has a configuration of rotating a larger one of large and small pinion gears having the same shaft with a rack gear connected to an outer case by pressing down the outer case, and pressing down the rack gear attached with punching blades with the smaller pinion gear, to punch documents.

Description

この発明は、穿孔刃の駆動にラックギヤとピニオンギヤを使用する２穴パンチ具に関する。  The present invention relates to a two-hole punching tool that uses a rack gear and a pinion gear to drive a drilling blade.

従来の２穴パンチ具は梃子の原理を利用している。  Conventional two-hole punch tools use the principle of leverage.

従来の２穴パンチ具を安定的に使用するためには、力点であるハンドル部は、操作中は常にパンチ具の基台の外周に立てた垂線で囲まれた範囲内になければならない。多数枚の紙を弱い力で穿孔するためには支点と力点との距離を大きくすればよいが、このためにはハンドル部が大きくなり、必然的にパンチ具基台の奥行きが長くなり、設置スペースを大きくとることになる。  In order to use the conventional two-hole punching tool stably, the handle portion which is a power point must always be within the range surrounded by the perpendicular line standing on the outer periphery of the base of the punching tool during operation. In order to punch a large number of sheets with a weak force, the distance between the fulcrum and the force point should be increased. However, for this purpose, the handle becomes larger and the depth of the punch base is inevitably increased. It will take up a lot of space.

本発明は、パンチ具基台の奥行きが短くて、しかも、大きな穿孔能力を持つ２穴パンチ具を提供することを課題とする。  An object of the present invention is to provide a two-hole punch tool having a short punch tool base and a large punching ability.

上記の課題を解決するために、本発明の２穴パンチ具は、外ケースを押し下げることにより外ケースに連結されたラックギヤで軸を同じくする大小のピニオンギヤのうち大きい方を回転させ、小さいほうのピニオンギヤで穿孔刃が取り付けられたラックギヤを下方に押し下げて書類を穿孔する構成とした。  In order to solve the above problems, the two-hole punching tool of the present invention rotates the larger one of the large and small pinion gears having the same shaft by the rack gear connected to the outer case by pushing down the outer case, The rack gear to which the punching blade is attached by the pinion gear is pushed downward to punch the document.

本発明の２穴パンチ具は、ラックギヤとピニオンギヤを使うものであって、力を穿孔刃のほぼ真上から真下に加える構造であるため、穿孔刃駆動部分の奥行きは数センチもあれば十分である。また、基台の奥行きも穿孔刃駆動部分を固定するためのスペース、穿孔する書類の端から穿孔孔までの適当な距離、穿孔孔周辺のスペースが確保されれば十分機能するため、従来の小型の２穴パンチ具より大幅に短縮することが可能である。  The two-hole punching tool of the present invention uses a rack gear and a pinion gear, and has a structure in which force is applied from almost directly above the drilling blade. is there. In addition, the depth of the base functions sufficiently if the space for fixing the drilling blade drive part, the appropriate distance from the end of the document to be punched to the punching hole, and the space around the drilling hole are secured, so the conventional small size It can be significantly shortened compared to the two-hole punch tool.

以下、本発明の実施の形態を図１、図２に基づいて説明する。  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.

外ケース６を下方に押し下げると入力ラックギヤ１が下方に押し下げられ２段ピニオンギヤ２の大きい方が回転される。これに伴い、２段ピニオンギヤ２の小さい方も回転し出力ラックギヤ３が下方に押し下げられ、穿孔刃４が下方に押し下げられる。この際、左右の内側の２段ピニオンギヤ２を連動させると左右の入力ラックギヤ１が均等に押し下げられる。  When the outer case 6 is pushed down, the input rack gear 1 is pushed down, and the larger one of the two-stage pinion gears 2 is rotated. Along with this, the smaller one of the two-stage pinion gear 2 also rotates, the output rack gear 3 is pushed down, and the drilling blade 4 is pushed down. At this time, when the left and right inner two-stage pinion gears 2 are interlocked, the left and right input rack gears 1 are evenly pushed down.
