あけ用の穿孔錐を穿孔機本体に対し着脱させるための穿
孔錯着脱装置に関するものである。Specifically, in a punching machine used to make a binding margin equal to the number of binding rods in the metal fitting on one side of a piece of paper to be bound into a binding metal fitting such as a file or binder, a perforating awl for making holes is used. This invention relates to a drilling complex attachment/detachment device for attachment/detachment to/from a drilling machine body.

れている。Conventional punching machines are not configured so that multiple punching holes can be attached to and removed from the punching machine body, and, for example, when punching different numbers of binding margins on sheets of paper, an unnecessary driving device for the punching holes is required. This is done by interrupting the interlocking state of the engine, and this interlocking state is configured to be interrupted via a clutch.

従って綴代の数が異なるとその都度クラッチを操作しな

て駆動装置に連動すべく構成しなければならず、穿孔機
本体側の構造が複雑になる等の問題があった。Therefore, if the number of binding margins differs, the clutch must be operated each time, which not only requires time and effort to drill holes, but also creates the risk that the clutch may become half-clutched, causing damage to various parts. Moreover, each of the plurality of drilling holes (usually a maximum of 30 holes) must be configured to be linked to the drive device through a clutch, resulting in problems such as the complexity of the structure of the drilling machine itself. was there.

そこで本考案は斯かる問題点を解決すべく考案したもの

ある。As explained above, the punching machine according to the present invention is capable of attaching and detaching the punching weaners to the punching machine body through an integrated holder having an appropriate number of punching weaners, and by replacing the punching weaners with this holder integrated. Since it is designed to open the desired number of wires on the side of the paper strip, even if a different number of wires are drilled on the paper strip, it is possible to replace the puncture and weaning with the integrated holder to ensure no mistakes. It is simple and easy to perform, and to replace the punching and weaning, the holder with the punching and weaning is stored in advance directly opposite the box-shaped attachment/detachment tool, and this attachment/detachment tool is attached to the main body of the punching machine. Since the weaner is attached to the punching machine body together with the holder through this attachment/detachment tool, the weaner can be attached and detached very easily and quickly, and it can be placed in the set position. It can be installed accurately, and by doing so, the structure of the main body of the punching machine can be made extremely simple. In other words, each punching machine can be connected to a drive device through a clutch separately, which eliminates a complicated structure. This eliminates the need for additional treatments, making it possible to provide the product at an extremely low cost as a whole, and to reduce the risk of failure.
