Problems solved by technology

Therefore, for those who only need to support the surface and do not need the center gauge function, and for those who do not use the center gauge function on a daily basis, the existence of the stand-up piece becomes a burden when using a hole punch, etc.

Embodiment Construction

[0024] One embodiment of the present invention will be described below with reference to the drawings.

[0025] figure 1 It is a hole puncher which shows the center gauge to which this embodiment is applied. This hole puncher includes: a base 1, a holding frame 2 integrally erected from the upper end (the direction in which paper is inserted) of the base 1, and a punching shaft (not shown) that is housed in the holding frame 2 and can be raised and lowered. The shaft frame 4 and the operating handle 5 rotatably supported at the base end side on the upper end side of the above-mentioned holding frame 2 , and the lifting operation of the shaft frame 4 and the rotating operation of the operating operating handle 5 are interlocked in the holding frame 2 .

[0026] The pedestal 1 is a hollow thick plate structure with sufficient rigidity to support the holding frame 2 and the operating handle 5 as its appendage. At the two positions corresponding to the hole axis, a resin circula...

Abstract

To effectively enhance a gauge function for projecting and indenting arms on right and left sides of a pedestal. A pair of arms 6 are installed to a pedestal 1 projectably and indentably in a direction opposite to the pedestal 1, and base end sides of the arms 6 are interlocked with each other via a synchronous mechanism 7 in the pedestal 1 to pull a tip end side of both arms 7 from the pedestal. A paper is laid down between standing pieces 60 standing on the tip end sides of the arms 7, so as to determine a center of the paper. Each arm 6 is constituted by a plurality of arm bodies 6a, 6b, which are spaced from each other and connected with each other on tip end sides.

Description

technical field [0001] The present invention relates to a center gauge for center indexing of paper attached to a hole punch or the like. Background technique [0002] For example, since a hole punch for punching a hole is mainly used for punching a hole for bookbinding, the position of the hole usually needs to be fixed. Therefore, in conventional punches of this type, a center gauge for center indexing of the paper is generally attached to the base on which the stack of paper is loaded. [0003] However, as this kind of center gauge, it is conceivable to provide a pair of brackets that can protrude (protrude and sink) from the base in opposite directions, and the base ends of these brackets are linked in the base by means of a synchronization mechanism, and the two brackets are pulled out from the base. On the front end side of the support, the indexing of the center of the paper is carried out by sandwiching the paper between the standing pieces of the support set on the...
