Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention has a bottom body having a punching hole and a perforation body for cooperating with the punching hole to perforate a sheet such as paper, and inserts a sheet between the bottom body and the perforation body. Regarding the punch to be a club.

[0002]

[Prior art]

 As the punch, the upper pressing portion is manually pressed to move the punched body up and down by using a moment of force, or a male screw member is used for a female screw member integrated with the bottom body. It is common to manually perforate the perforated body, which is a member, by manually rotating the perforated body such that the screwing position of the perforated body is changed. However, in recent years, a so-called electric punch using a motor as a driving source of a punching body has also been known (for example, see Japanese Patent Laid-Open No. 2-232198).

[0003]

[Problems to be solved by the device]

 Whether punching manually or using an electric punch, the punch must be properly oriented when punching, which can be troublesome. The orientation is not well determined, and when perforated sheets are stitched together in a file, they often become irregular.

On the other hand, on the front side of the insertion portion of the seat insertion portion, there is a receiving body and a body, and it is possible to pass the sheet between the receiving body and the body. At this time, it can be solved by arranging a sheet penetrating body which applies a compressive force to the sheet as a sheet insertion guide for the sheet insertion portion.

However, when attempting to perforate a sheet having staples at the corners, the sheet insertion guide composed of the above-mentioned receiving body and the contradictory body does not correctly guide the sheet insertion direction. It may be a hindrance to you.

[0006]

[Means for Solving the Problems]

 On the front side of the insertion portion of the seat insertion portion, there is a receiver and a body, and a sheet can be inserted between the body and the body, but a sheet is applied with a pressure to insert the sheet. -The guide body is provided as a seat insertion guide for the seat insertion portion, and the positioning wall portion at the end of the seat to be inserted is provided on one side of the receiving body. Provide a gap between the receiving body and the body for a certain distance. That is, the present invention has a bottom body having a punched hole and a perforated body for punching a sheet in cooperation with the punched hole, and a seat insertion portion is provided between the bottom body and the perforated body. It is a punch that consists of a receiving body and a body on the front side of the insertion portion of the seat insertion section, and it is possible to pass the sheet between the receiving body and the body, but the sheet is -A sheet penetrating body that applies a penetrating force to the sheet is provided as a sheet insertion guide for the sheet inserting portion, and a positioning wall portion of the end portion of the sheet to be inserted is provided in the receiving body. The gist is a punch provided on one side and provided with a gap between the receiving body and the sandwiched body over a predetermined distance from the positioning wall portion.

[0007]

[Action]

 A case of punching on the left side of the vertically long sheet will be described as an example. When the sheet to be pierced is inserted into the seat insertion portion between the bottom body and the piercing body, the left side of the sheet comes into contact with the sheet penetrating body. At this time, if the left side of the sheet uniformly contacts the sheet passing body as a whole, the sheet is passed through as it is. However, in such a case, it is rare that either the upper part or the lower part of the left side of the seat first comes into contact with the sheet passing body. The user consciously or unconsciously changes the direction of the seat so that the other part of the left side of the seat that has not yet come into contact also comes into contact with the other part. In this way, the left side of the sheet comes into uniform contact with the sheet threading body as a whole, and then the sheet is passed through and inserted into the sheet insertion portion located ahead of the sheet and punched. At this time, even if the corners of the sheet are thickened by stapling or the like, this part is separated from the receiver and the cage over a predetermined distance from the positioning wall at the end of the sheet. Pass through the gap provided between them.

EXAMPLE An example is shown in the attached FIGS. In the punch P, the housing 1 has a rail 2 inside. The punch body 3 moves along the rail 2 to change its position. The one shown in the drawing moves about half of the right side of the housing 1 in the drawing. The punching position can be set according to the size of the sheet. Although illustration is omitted, this movement can be performed manually, or for example, a sensor for detecting the size of the sheet is provided in the punch P and a predetermined amount corresponding to the sensor detection is provided. It can also be automatically moved, such as moving.

The punch body 3 is suitable as a manual punch or an electric punch, and therefore, the internal structure thereof merely shows the existence of the punched body 4 in a perspective manner. By the way, a typical electric punch is capable of automatically punching when a sheet is inserted by sensing with a micro switch, which is more uneven in the sheet insertion direction than a manual punch. Since it is easy, it is a suitable object of the present invention. Further, when the number of perforated bodies 4 is more than one, the sheet insertion direction is more likely to be misaligned, so that the illustrated one has two perforated bodies 4, a so-called two-hole punch. There is.

The perforated body 4 moves in the vertical direction in the drawing, and a seat body 5 is formed below the bottom body 6 to form a seat insertion portion 5. Reference numeral 6a is a punching hole.

Below the bottom body 6 is a drawer box 7 for accommodating perforated scraps, and the top cover is a receiving body 8. The receiver 8 has a cutout portion 8a corresponding to the movement of the punch body 3.

The receiving body 8 is aligned with the top surface of the bottom body 6, and also serves as a seat mounting table when the sheet S is inserted, on which the sandwiched body 9 is mounted. The cage 9 is a columnar body, and forms a sheet insert body together with the receiver 8, and the sheet S lifts the cage 9 and rotates while passing it. Therefore, the shaft hole 10a of the armpit body 10 that pivotally supports the sandwiched body 9 is elongated in the upper and lower parts.

The armpits 10 are located on both sides of the receiving body 8 and the sandwiched body 9. Of these, the inner wall 10b on the right side of the drawing serves as a positioning wall portion at the end of the sheet S. That is, the size of the sheet S is not constant. The two-hole punch is usually used to punch holes at equal distances from both ends of one side of the sheet S, and therefore the punch body 3 can be moved. Corresponding to about half of the case 1 on the right side of the drawing, the sheets S having different sizes are inserted along the inner wall 10b of the side body 10 on the right side of the drawing.

Then, a predetermined distance from the inner wall 10b of the side body 10 on the right side of the drawing, specifically, slightly larger than the portion where the sheet S is thickened by stapling, for example, about 3 cm. The receiving body 8 has a hollow portion 8b, and the holding body 9 has a small diameter portion 9a. As shown in FIG. 2, due to the gap 11 formed by the recess 8b of the receiving body 8 and the small diameter portion 9a of the sandwiched body 9, the portion of the sheet S thickened by the staple 12 etc. It will be inserted without being disturbed by the body 9.

Although an example has been described above, various other methods are possible. For example, the positioning wall portion at the end of the seat may be provided independently of the armpit body 10. Alternatively, the bottom body may be a cylindrical body similar to the sandwiched body 9, and the gap 11 may be formed by the small diameter portions of both cylindrical bodies.
