JPH0740095U - Punch with 4-hole positioning pin - Google Patents

Abstract

(57) [Abstract] [Purpose] The present invention inserts a cutting blade into a hole punched by a two-hole punch and uses the guide as a guide to cut the hole to cause a positional deviation of the hole to be punched later, or to visually check the subsequent hole. The purpose is to prevent misalignment when drilling and to accurately drill four holes at the same pitch. [Structure] A bar is projected on a side of a line connecting a base cutting blade of a punch for two holes, and a pin fitted to a perforation of a bundle of paper is projected at a specified distance position between two holes from the cutting blade on the bar side. Punch with 4-hole positioning pin.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a punch with a four-hole positioning pin having a positioning pin that can accurately drill four holes without fitting a cutting blade into a hole punched by a two-hole punch and using it as a guide.

[0002]

[Prior art]

 Conventionally, in order to punch four holes with a two-hole punch, two holes are punched in a central portion or one side portion of a predetermined position of a sheet bundle, and then this punching is used as a reference for punching or punched holes. One of them was used as a guide, one cutting blade was inserted, and one hole was sequentially drilled to form four holes.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional technique, since the former is perforated by visual inspection, a slight deviation occurs. If there is any deviation, it will be extremely difficult to insert the four holes in the pin of the file. On the other hand, in the latter case, when the cutting blade is fitted again into the drilled hole, it will be possible to fit it correctly. There was a problem in that it was not possible to punch holes at the correct positions, and it was extremely difficult to insert the four holes into the pins of the file. The present invention aims to solve the above problems.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has a bar protruding from the side of the line connecting the base cutting blades of a two-hole punch, and fitted into the perforation of a bundle of paper at a specified distance between the two holes from the bar-side cutting blade. It is characterized by protruding pins that fit together.

Embodiment 1 FIG. 1 shows a first embodiment of the present invention. Reference numeral 1 is a well-known punch, in which a paper stack placing portion 3 having a step portion 3a is formed on the front upper surface of the base 2, and fixed arms 4 are provided on both upper sides of the paper stack placing portion 3, and a pressing lever is applied to a pin 5 of the base. -6 is attached so that it can move up and down, and it is always urged upward by a spring, and a cutting blade 7 is attached near the pin 5. The pressing lever 6 is integrally connected at the connecting portion. According to the present invention, in the above-mentioned well-known punch, a bar 8 is provided so as to project to the side of a line connecting the pair of cutting blades 7 of the base 2, and the tip of the bar 8 has a distance of 1 pair. A pin 9 that fits into the drilling is provided at a position spaced apart between the cutting blades 7. Near the base of the bar 8, an A4 side edge alignment position mark 10 and a B4 side edge alignment position mark 11 are displayed.

Next, the usage method will be described. A case will be described in which four holes are formed in the sheet bundle B4 at the same pitch P. The B4 sheet bundle 13 is placed on the sheet bundle placing section 3 of the punch 1, and the leading end is brought into contact with the stepped portion 3a to align the leading ends, and one side is aligned with the B4 mark 11 as shown in FIG. The holes 1'and 2'are punched by the cutting blade 7. Then, the bundle of paper is shifted to the right, and the hole 1'is fitted into the pin 9 of the bar 8. At this time, the pitch between the pin 9 and the inner cutting blade 7 is the pitch P of the pair of cutting blades 7, so that the holes 1 ', 2', 3 ', 4'have the same pitch P. Become.

Next, as shown in FIG. 4, the center 13 a in the width direction of the sheet bundle 13 is aligned with the center position mark 1 a of the cutting blade 7 of the punch 1, and holes 1 ′ and 2 ′ are punched by the pair of cutting blades 7. Next, the sheet bundle 13 is shifted to the right, and the hole 1'is fitted into the pin 9 of the bar 8 as shown in FIG. Next, as shown in FIG. 6, the sheet bundle 13 is turned over and the hole 2'is fitted into the pin 9 of the bar 8 to form the hole 4 '. In this way, holes 1 ', 2', 3 ', 4'having the same pitch can be drilled.

FIG. 7 shows a second embodiment of the present invention. A sheet bundle positioning bar 14 is projected from the base 2 on the side opposite to the bar 8 of the first embodiment. The other structure is similar to that of the first embodiment.

Next, the usage method will be described. A case will be described in which four holes are formed in the B4 sheet bundle at the same pitch. The B4 sheet bundle 13 of B4 is placed on the sheet bundle placing section 3 of the punch 1, and the leading end is brought into contact with the stepped portion 3a to align the leading ends, and as shown in FIG. The holes 1'and 2'are punched by a pair of cutting blades 7. Then, the sheet bundle 13 is turned over and the hole 2'is fitted into the pin 9 of the bar 8, and the holes 3'and 4'are punched by the pair of cutting blades 7. The holes 1 ′, 2 ′, 3 ′, 4 ′ all have the same pitch P.

[0010]

[Effect of device]

 According to the present invention, a bar is projected on the side of a line connecting the base cutting blades of a punch for two holes, and a pin to be fitted into the perforation of the sheet bundle is projected at a specified distance position between the two holes from the bar side cutting blade. Since it is installed, it is possible to accurately drill four holes at the same pitch.
