In FIG. 1, the cover 170 is not shown.
The small punch according to the first embodiment includes an operation lever 110, a swing member 130, a support member 140, a first drilling blade 150, a second drilling blade 160, a cover 170, and a punch base 200. Is provided. The operation lever 110, the swing member 130, the support member 140, the first perforation blade 150, the second perforation blade 160, and the cover 170 are disposed on the punch base 200.

The operation lever 110 includes a long plate-shaped operation unit and two side surfaces extending downward near one end of the operation unit. A first drilling blade 150 is attached by a connecting rod 151 between two side surfaces of the operation lever 110.
The sliding member 130 is composed of two long flat plates facing each other. A support member 140 is fixed to the upper surface of the punch base 200. The two flat plates of the swing member 130 are attached to the support member 140 so as to be swingable by a connecting rod 141 at the center thereof. Thereby, the peristaltic member 130 is attached to the upper surface of the punch base 200. The two flat plates of the sliding member 130 are lowered when one end is raised, and lowered when the other end is lowered.
The two flat plates of the swing member 130 are arranged so as to sandwich the two side surfaces of the operation lever 110.
The two flat plates of the swing member 130 and the two side surfaces of the operation lever 110 are connected by a connecting rod 111 so that the operation lever 110 and the swing member 130 can be opened and closed. As a result, one end of the operation lever 110 is connected to one end of the swing member 130.
A second drilling blade 160 is attached to the other end of the two flat plates of the swing member 130 by a connecting rod 161.

A first hole 210 and a second hole 211 are open on the upper surface of the punch base 200. The lower portions of the first drilling blade 150 and the second drilling blade 160 are inserted into the first hole 210 and the second hole 211, respectively. The first hole 210 and the second hole 211 guide the vertical movement of the first drilling blade 150 and the second drilling blade 160, respectively.
The punch table 200 has an elongated gap 201 extending horizontally. The gap 201 is for inserting a sheet. The edge of the sheet is inserted into the gap 201 when the operation lever 110 and the swing member 130 are open. When the operation lever 110 and the swing member 130 are closed, the first punching blade 150 and the second punching blade 160 punch holes in the paper inserted in the gap 201 of the punch base 200.
The punch base 200 includes a perforated waste container. There is a lid 230 on the bottom surface of the punch base 200. The lid 230 can be opened to remove the perforated waste from the perforated waste storage container.
In addition, a paper guide 220 is stored in the punch table 200. The paper guide 220 includes a paper stopper 221 at the end thereof. The paper punching position can be determined by pulling out the paper guide 220 in accordance with the paper size such as A4.
The cover 170 is disposed on the upper surface of the punch base 200 so as to surround the swing member 130.

FIG. 3 schematically shows the operation lever 110 and the swing member 130. FIG. 4 schematically shows an example of the movement of the operation lever 110 and the swing member 130.
The solid line arrows and the broken line arrows in FIG. 4 indicate the directions in which the operation lever 110 and the swing member 130 move, respectively. A horizontal line 131 indicated by a broken line passes through a connecting point (connecting bar 141) where the swinging member 130 and the support member 140 are connected. The swing member 130 swings around the horizontal line 131 around the connecting rod 141. FIG. 4 shows an example in which one end and the other end of the swing member 130 are separated from the horizontal line 131 to the maximum distance Y.
As shown in FIG. 4A, when the operation lever 110 and the swing member 130 are opened, the operation lever 110 intersects the horizontal line 131 at a point spaced from the one end of the operation lever 110 (and one end of the swing member 130) by the interval X. . At this time, one end of the operation lever 110 (and one end of the swinging member 130) is separated from the horizontal line 131 by a distance Y. 4B, when the operation lever 110 and the swing member 130 are closed, the operation lever 110 is positioned above the horizontal line 131 by a distance Y from the horizontal line 131.

  FIG. 5 is an enlarged view of region A in FIG. As shown in FIG. 5, the distance between the position on the operation lever 110 and the one end of the operation lever 110 that is separated from the horizontal line 131 by a distance Y is 2X. As shown by a solid arrow in FIG. 4A, when the operating lever 110 and the swinging member 130 in the opened state are closed, the portion of the operating lever 110 from its one end to the position of the interval 2X rises. The portion separated by 2X or more from the distance descends. On the other hand, as shown by a solid arrow in FIG. 4B, when the operation lever 110 and the swinging member 130 in the closed state are opened, the operation lever 110 is lowered from the end to the position of the interval 2X, A portion away from the one end by a distance of 2X or more rises. Therefore, when the first drilling blade 150 is attached at a position 2X or more away from one end of the operation lever 110, the first drilling blade 150 and the second drilling blade 160 are opened and closed when the operation lever 110 and the swing member 130 are opened and closed. Move in the same direction.

For example, as shown in FIG. 5, the distance between the position on the operation lever 110 and the one end of the operation lever 110 that is apart from the horizontal line 131 by a distance 3Y is 4X. When the first drilling blade 150 is attached to this position, the first drilling blade 150 is lowered by a distance 2Y when the operating lever 110 and the swinging member 130 in the opened state are closed. At this time, the second drilling blade 160 is also lowered by the distance 2Y. Further, when the operation lever 110 and the swinging member 130 in the closed state are opened, the first drilling blade 150 is raised by the distance 2Y. At this time, the second drilling blade 160 is also raised by the distance 2Y.
The total length of the swing member 130 is 10.10 cm (half length L = 5.05 cm of the swing member 130), and the angle formed between the horizontal line 131 and the swing member 130 in a state where the operation lever 110 and the swing member 130 are fully opened. Assuming that a = 3.965 ° and the angle b formed by the horizontal line 131 and the operation lever 110 = 33.690 °, 4X = 2.10 cm and 2Y = 0.70 cm. That is, when the first drilling blade 150 is attached at a position separated by an interval of 2.10 cm from one end of the operation lever 110, the first drilling blade 150 and the second punching blade 130 are opened and closed when the operation lever 110 and the swing member 130 are opened and closed. The drilling blade 160 moves up and down 0.70 cm in the same direction.
At this time, the distance (2L-4X) between the first hole 210 and the second hole 211 is 8.00 cm. This is a size in which four holes can be punched in the long side of A4 paper by punching the long side of A4 paper in half in half while the paper guide 220 is housed in the punch table 200. is there. In addition, this small punch can pull out the paper guide 220 from the punch table 200 to determine the punching position of B5 paper, A4 paper, etc., and punch two holes in B5 paper, A4 paper, etc.

As shown in FIG. 6, in order to raise the operation lever 110, the first drilling blade 150 and the second drilling blade 160 are urged upward by an elastic member (not shown) such as a spring. However, the urging force applied to the second drilling blade 160 pushes up the other end of the peristaltic member 130 and pushes down one end thereof (that is, one end of the operation lever 110) downward. This downward pressing force cancels the upward biasing force applied to the first drilling blade 150. For this reason, when the urging forces applied to the first drilling blade 150 and the second drilling blade 160 are approximately the same, they do not affect the operation of the operation lever 110.
Further, unlike the small punch described in Patent Document 1, the small punch according to the present embodiment does not require a force for sliding the tip of the operation lever.
Therefore, in the small punch according to the present embodiment, most of the downward force applied to the operation lever is used to make a hole in the paper.
