Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper punch, and particularly to a paper punch for notebook paper that is attached to a binder-attached system notebook.

[Conventional technology]

In recent years, with the diversification of the amount and type of information, many types of notebooks have been sold, and among them, notebooks with binders are widely used because of their convenience, such as the ability to freely attach notebook paper.

Recently, so-called system notebooks with multi-hole binders, typically 6-hole ones, have attracted attention and are widely used by businessmen. The notebook paper that is attached to the binder of the system planner is, for example, one that does not meet the Japanese Industrial Standards JIS-P-0138 (Paper Processing Finished Dimensions) and has a size of approximately 171 mm x 95 mm (hereinafter referred to as refill paper). ). For example, a system planner with a binder (hereinafter referred to as a re-feel format notebook) to which this re-feel paper is attached has a 6-hole binder, and a paper punch that punches holes for the binder that fits this is manufactured for the re-feel format system notebook. 6
A paper punch having several perforating blades is known.

[The problem that the idea aims to solve]

The conventional multi-hole paper punches mentioned above are only for paper of a specific size, such as refill paper, and cannot be used for punching paper that is attached to other types of binder notebooks. The main body is the same size as the length of a particular paper, such as refill paper, in the direction of the hole arrangement, and as a desk office item, it is relatively large and heavy.

To solve the problems of the prior art, the object of the present invention is to provide a paper punch for a multi-hole binder notebook which is small, easy to use, and can be used not only for notebook paper to be attached to a specific binder notebook, but also for notebook paper to be attached to other binder notebooks.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a plate-like lever, a perforating blade that moves up and down by operating the plate-like lever, a base provided with a perforation through which the perforating blade passes, and a base provided with a perforation through which the perforating blade passes. A paper punch for making binder holes in the notebook paper of an even-numbered binder notebook, which has a dust receptacle cover arranged, the number of the punching blades being half of the number of pawls of the binder, and the punching blade of the plate-shaped lever. The length from the positioning end in the arrangement direction to the punching blade adjacent thereto, and the length from the positioning end of the dust tray cover to the punching blade adjacent thereto when the scrap tray cover is installed horizontally in the opposite direction. is set to be equal to the length from one end in the hole arrangement direction of the notebook paper attached to the first binder notebook and the second binder notebook, respectively, to the perforation adjacent thereto.

[Effect]

The number of punching blades is half of the number of binder pawls in the binder notebook, and the length from the positioning end of the plate lever in the punching blade arrangement direction to the punching blade adjacent thereto is equal to the length of the notebook paper attached to the first binder notebook. By making the length equal to the length from one end in the hole arrangement direction to the adjacent perforation, when one end of the notebook paper in the hole arrangement direction is perforated in alignment with the positioning end of the plate-like lever, the length in the hole arrangement direction of the notebook paper is Drill half as many holes as the number of binder nails in one half. Next, turn the notebook paper over and punch the other end in line with the positioning end of the plate-like lever in the same way as above, and the remaining half of the notebook paper in the hole arrangement direction will have holes for the binder, creating a binder notebook with many holes as a whole. Binder holes can be drilled to match the binder. Also, when the dust catcher cover is installed horizontally in the opposite direction, the length from the positioning end of the dust catcher cover to the punching blade adjacent to the end from one end in the hole arrangement direction of the notebook paper in the second binder notebook. By making the length equal to the length up to the binder hole adjacent to the end, when the positioning end of the waste receiving cover is used as a reference and the positioning end of the plate-like lever is operated in the same manner as when the positioning end of the plate-like lever is used as a reference, the first binder A hole for the binder can be made in the notebook paper attached to the second binder notebook, which has a size different from that of the notebook.

The material of the present invention may be metal, reinforced plastic, etc., but any material that can withstand the strength of the paper punch may be used. Additionally, a rubber sheet may be attached to the back surface of the dust tray cover to prevent it from slipping off the desk or the like.

〔Example〕

Next, the present invention will be explained in more detail with reference to examples.

FIG. 1 is a perspective view of a paper punch showing an embodiment of the present invention, and FIG. 2 is a side view thereof. This paper punch includes a plate-like lever 1, a plurality of (for example, three) perforating blades 2 that descend by pushing down the plate-like lever 1, and a base 3 having a perforation 5 through which the tips of the perforating blades 2 pass. It mainly consists of a waste receiving cover 4 disposed at the lower part of the base 3 for receiving punched paper pieces, and a spring 9 for pushing up the lowered punching blade 2. In such a configuration, when drilling holes (for example, 6 holes) for the binder in the notebook paper to be attached to the first binder, the dust tray cover 4 is attached to the base 3 in the standard orientation, and the second When punching binder holes (for example, 6 holes) in a notebook paper to be attached to a binder notebook, the dust receptacle cover 4 is attached to the base 3 horizontally in the opposite direction.

Next, specific examples of the present invention will be described.

FIG. 3 is a front view showing the paper punch of the present invention in which the waste receiving cover 4 is attached to the base 3 in a standard orientation. This paper punch is a paper punch for a 6-hole binder that can be used for a system notebook with a 6-hole binder that attaches re-feel paper (re-feel size system notebook) and an A5 version 6-hole system notebook with a binder (hereinafter referred to as the A5 size system notebook). It is. In the figure, the dust catcher cover 4 is attached to the base 3 in a standard orientation, and both ends of the dust catcher cover 4 and the positioning ends of the plate-like lever 1, that is, the side ends 6 and the center end 7, are aligned with each other. ing. 6A, the length from the side edge 6 to the punching blade 2 adjacent to the edge is the same as the length from one end in the hole arrangement direction of the refill paper in the refill format notebook to the punching hole for the binder adjacent thereto. In other words, the mark 7A indicating the side edge is such that the length from the center side edge 7 to the punching blade 2 adjacent to the edge is from the center in the hole arrangement direction of the refill paper in the refill size system notebook. This mark indicates that the length is the same as the length to the hole in the binder near the center, that is, the end on the center side.

By aligning one end of the re-feel paper in the hole arrangement direction with the side edge 6 of the plate-like lever 1 and performing a punching operation, three binder holes are made in half of the re-reel paper in the hole arrangement direction, and then the re-reel paper is punched. By turning the paper over and punching the other end in the same manner as the side edge 6, six holes that fit into the binder of the refill-sized notebook are created. In addition, if you want to punch holes for a binder that fits a re-feel size notebook on paper that is larger than re-feel paper, or on paper that is large enough to make 6 holes but smaller than re-feel paper, you can fold the paper in half, etc. Then, find the center of the hole arrangement direction, align the center with the center side edge 7 of the plate-like lever 1, and punch holes.Next, turn the paper over and punch the holes in the same way. You can make holes that fit into the binder of your refillable notebook.

FIG. 4 is a front view showing the paper punch shown in FIG. 3 in a state where the dust receptacle cover 4 is horizontally reversed and attached to the base 3. In the figure, the dust catcher cover 4 is attached to the base 3 horizontally in the opposite direction, and the length from the positioning end of the dust catcher cover 4, that is, the protruding end 8 to the punching blade 2 adjacent to the end, is the A5 size system notebook. It is configured to be equal to the length from one end of the A5 size paper in the hole arrangement direction to the binder hole adjacent to the end.

One end of the A5 size paper in the hole arrangement direction is connected to the protruding end 8.
By punching holes to fit the length of the A5 paper, three binder holes are created in the longitudinal half of the A5 paper.Next, by turning the A5 paper over and punching holes in the same way, the total size matches the binder of the A5 size notebook. Six holes are drilled.

Both the refill size system planner and the A5 size system planner have 6 binder tabs, and the spacing between each 3 holes is the same, with 3 holes arranged above and below, but the size of the notebook, that is, the notebook paper Due to the difference in size, the gap between the bottom claw of the upper row and the top claw of the lower row is slightly wider in the A5 size system notebook, and the distance between the claws at the bottom of the upper row and the top row of the lower row is slightly wider in the A5 size system notebook. Also the distance between the nails
The A5 size notebook is slightly wider. Therefore, the length from the protruding end 8 to the punching blade 2 adjacent thereto is equal to the length from one end in the hole arrangement direction of the A5 size paper attached to the A5 size notebook to the adjacent hole for the binder. By repeatedly punching holes using the protruding end 8 as a reference, it is possible to punch six holes in an A5 sheet of paper that are compatible with the binder of an A5 size notebook.

According to this embodiment, the number of perforating blades 2 of the paper punch for refill paper attached to a refill size system notebook is three, and one end of the plate-like lever 1 is connected to the side end, that is, the perforation blades 2 from the end to the end adjacent to the end. The length to the blade 2 is made equal to the length from one end in the hole arrangement direction of the refill paper in the refill format notebook to the adjacent binder hole, and the other end of the plate-shaped lever 1 is set to the center side end 7. That is, the length from the end to the punching blade 2 adjacent to the end is equal to the length from the center in the hole arrangement direction of the refill paper attached to the refill system notebook to the binder hole adjacent to the center. Therefore, by aligning one end or the center of the re-feel paper with the side edge 6 or center edge 7 and repeating the punching operation, it is possible to punch six holes that fit the binder of the re-feel size notebook. In particular, when punching refill-sized paper that you do not want to fold in half, cannot fold in half, or whose center is not clearly defined, punching using the side edge as a reference is effective. If you want to attach paper that is smaller than refill paper to a refill system notebook, punching with the center side edge as a reference is effective.

Furthermore, according to this embodiment, when the dust receptacle cover 4 is horizontally reversed and attached to the base 3, the length from the protruding end 8 to the punching blade 2 adjacent to the end is determined as A5 in the A5 size system notebook. By making the length equal to the length from one end of the paper in the hole arrangement direction to the hole for the binder adjacent to that end, it can be used not only for refill size system notebooks, but also as a punching tool for A5 size paper that can be attached to A5 size system notebooks. It can also be used. Furthermore, according to this embodiment, the paper punch main body can be made smaller and lighter, reducing manufacturing costs and improving operability.

[Effects of the Invention] According to the present invention, it is small and easy to use, and can be used not only as a paper punch for a specific binder notebook but also as a paper punch for binder notebooks of other sizes, expanding the range of use.
