JP2001157995A - Punch provided with mirror - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve problems in conventional methods such as requiring labor of folding paper, and forming an unnecessary folding mark in the paper in two-folding the paper to form the folding mark to a mark on a center line in a punch, requiring a space for a gauge protruded sideways from the punch, achieving effect only for paper of regular sizes, and requiring labor of setting the gauge to the size of the paper even when it is regularly sized. SOLUTION: A mirror 1 is provided on this punch in such a way that a mirror surface or its extension is perpendicular to a line 23 passing the centers of receiving holes 21, 22 bored in a base 28, and includes center points of the receiving holes 21, 22. This means that the mirror 1 is provided at a position where the receiving holes 21, 22 are symmetric to each other to the mirror surface.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION Generally, when a document is bound as a file, two holes are formed along one edge of the paper, and the holes are bound through two rods. A punch is used to drill these two holes. At this time, these two holes must always be made symmetrically with respect to the center line of the paper in order to align and bind the papers neatly. That is, the paper must be set so that the center line of the paper coincides with the center line of the perforator. The present invention is a perforator for filing a document, in which the center line of the paper is determined by the action of a mirror, and it is easy to correctly set the paper in the perforator as described above. However, the center line (35) of the paper refers to a line that bisects the paper into two congruent rectangles as shown in FIG. The center line (24) of the perforator is perpendicular to a line (23) passing through the center of each of the receiving holes (21) and (22) as shown in FIG. 1, FIG. 2 or FIG. This is a line on the base (28) passing through the center point of the receiving hole, and at the same time is a line at which the extension surface of the mirror (1) intersects the base (28).

2. Description of the Related Art There are two conventional methods for correctly setting a paper on a punch. The simplest and most common method is to fold the paper in two, set the fold as the centerline of the paper, and set it to the mark provided on the centerline of the perforator.
Another method is to use a gauge that measures the size of a fixed paper. This sets the gauge to the size of the paper,
Set the paper by aligning the edge of the paper with the edge of the gauge.

[0003]

The conventional method has the following problems. The method of folding the paper into two and aligning the fold with the mark on the center line of the punch takes time and effort to fold the paper,
Also, unnecessary folds remain on the paper. The method of using a gauge takes up space because the gauge protrudes from the side of the perforator. Further, the effect cannot be exerted with paper other than the fixed size paper, and furthermore, even with the fixed size paper, a gauge must be set to the size, which is troublesome.

[0004]

A mirror surface or an extension thereof is formed in a receiving hole (21), (22) formed on a base (28).
A mirror (1) is provided in the perforator, perpendicular to a line (23) passing through the center of each of the above and including the midpoint of these receiving holes.
That is, the mirror (1) is provided at a position where the receiving holes (21) and (22) are symmetric with respect to the mirror surface. Here the receiving hole (2
1) and (22) are holes on the base (28) which are the receiving side of the cylindrical blade when a circular hole is made by penetrating a cylindrical blade through the paper.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Since the stoppers (25) and (26) and the receiving holes (21) and (22) are arranged in parallel, as shown in FIG. When (31) touches, edge (31) is parallel to line (23). Since line (23) is perpendicular to mirror (1), edge (31) is also perpendicular to mirror (1). Since the paper (3) is rectangular, the edge (32) and the edge (33) are parallel to each other across the mirror (1) and parallel to the mirror (1). When the paper (3) is set in the correct position,
The center line (35) of the paper coincides with the center line (24) of the perforator, as shown in FIGS. Therefore, the edge (3
2) and the edge (33) are located symmetrically with respect to the mirror (1).
At this time, as shown in FIG. 3, from the viewpoint (4), the apparent position of the edge (34) which is a virtual image of the edge (33) reflected on the mirror (1) coincides with the edge (32). Thus, as shown in FIG. 2, the edge (34) is the edge (32) visible to the left of the mirror (1).
Looks straight alongside. If the paper (3) is not set in the correct position, the center line (35) of the paper does not coincide with the center line (24) of the perforator as shown in FIGS. The edge (33) does not have a symmetrical relation to the mirror (1). At this time, as shown in FIG. 5, from the viewpoint (4), the apparent position of the edge (34) is the edge (3).
Does not match 2). Therefore, as shown in FIG.
4) and the edge (32) seen to the left appear to be shifted vertically. That is, the user moves the edge (31) along the stoppers (25) and (26) in order to set the paper (3) correctly, and as shown in FIG. The edge (34) is made to look straight as shown in FIG. When the paper is set in this manner, two holes for the file can be formed symmetrically with respect to the center line (35) of the paper. In FIGS. 3 and 5, the edge (3
3) and (34) hang down by gravity. But they also hang down, so the principle remains the same. Therefore, the paper (3) is shown horizontally here for the sake of simplicity.

[0006]

Embodiment 1 In Embodiment 1, as shown in FIG. 1, a mirror (1) is mounted on a handle (27) via a bracket (11). In the second embodiment, the mirror (1) is attached to the base (28) via the bracket (12) as shown in FIG.

[0007]

The paper can be set at the correct punching position of the perforator simply by positioning the paper so that the edge of the paper reflected on the mirror and the edge of the paper visible outside the mirror appear straight. At this time, it is not necessary to fold the paper in order to center the paper, and there is no need for a gauge.
