Abstract

(57) [Summary] An L-shaped plate-shaped metal (or resin) 1 is attached so that it can be pulled out inside a place that does not interfere with the use of the punch.
A paper length setting portion (concave type) 3 and a positioning leaf spring 4 are provided so that the length of the punch center position 6 from the tip 2 of the device 1 is half-fixed at half 8 of the corresponding paper. A device that prints the type of. [Objective] When filing a document using a small punch, to make a hole easily and accurately with the center of the document as the reference. [Configuration] L-shaped plate-shaped metal (or resin) 1 is provided with setting portions (concave type) 3 according to the size of the paper, which is specified for each paper and is semi-fixed at each location. It is composed of a positioning leaf spring 4, and is characterized in that it can be incorporated in a small punch.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 When filing documents in offices, etc., a small punch is generally used to open a hole for filing. At this time, the center position of the paper cannot be determined smoothly, and most people fold the document and make creases to find the center position. The present invention is an apparatus that can easily and securely set the center position of a document to a small punch.

[0002]

[Prior art]

 In the conventional positioning device, the size of A4, B5, etc. is clearly marked on the paper tray, as is the case with large office supplies (cutters), or the position is determined by a stopper device.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. (B) The main purpose of the conventional device is to process all dimensions of the relevant paper (document), and it is not suitable for determining the center position like a punch. (B) There is a limit to downsizing with the conventional method, and the size of paper is the minimum required. The present invention is aimed at downsizing, excluding these drawbacks.

[0004]

[Means for Solving the Problems]

 In general, most people who are involved in clerical work and make copies every day are able to easily distinguish between A4 and B5 documents. In order to find the center position that is important for the punch, one-sided positioning does not require the entire size of the paper, half the size, and it can be built in a small punch.

[0005]

[Action]

 For each document to be punched, pull out the device 1 and semi-fix it on the corresponding sheet LS (long and short). By aligning the leading edge of the document with the document stopper part 2 of the device 1 and inserting the document all the way, the center 8 of the document can be accurately set at the center position 6 of the punch 5. Other paper can be used as before, so there is no problem.

[0006]

【Example】

 (B) The tip of a plate-shaped metal (or resin) 1 is bent into an L-shape 2 and attached so that it can be pulled out inside a place that does not interfere with the use of the punch. The opposite tip is also processed into an L-shape to prevent it from coming off. (B) The paper setting part (concave type) 3 is set at several places and the positioning leaf spring 4 is set so that the length of the central position 6 of the punch 5 is semi-fixed at a position half of the corresponding paper size by the device 1 2. The type name of the paper is printed so that it can be installed and confirmed from the outside. The length of the device 1 can be built in a small punch as long as it is the maximum length of A5 portrait of a commonly used sheet. Further, if the apparatus 1 has an expandable structure, B4 paper is not impossible.

[0007]

【effect】

 By using the device of the present invention, the center of most A4 and B5 documents can be easily and surely set in the center of the punch, and the hole can be opened in the correct position. It is very beautiful even after filing, it does not break or bend due to misalignment, and the efficiency of paperwork can be expected considerably. Especially in the case of thick documents that cannot be folded, the effect is remarkable.

Claims (1)

[Scope of utility model registration request] 1. A drawing (1) in which a tip of a plate-shaped metal (or resin) 1 is bent into an L-shape 2 so that it can be pulled out into a place that does not hinder the use of the punch. In order that the length of the central position 6 of the punch 5 is half-fixed at the position of half of the relevant paper size from the device 2 2, the paper setting part (concave type) 3 is provided at several places and the positioning leaf spring 4, and from the outside. Print the paper type name so that you can check it. The center positioning device configured as described above.
