[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tabletop hole punch for a cylindrical paper tube that can be formed with through holes that are formed in a side surface of a cylindrical paper tube with a round hole and open on both side surfaces.
[0002]
[Prior art]
As is well known, a base part for storing a punched round piece of paper, a fixed arm part provided on the upper surface of the base part, one end side of which is rotatably supported by the fixed arm part, and the other end side is a free end. A document including a pair of punching shafts that are provided so as to be movable up and down in the fixed arm portion and have a required number of sheets stacked by rotating the operation arm portion. A tabletop punch that opens a pair of binding holes for overlapping and binding is widely used (for example, see Patent Document 1).
[0003]
In addition, a bar is protruded on the side of the line connecting the pair of punching shafts, and a pin for fitting the binding hole at a specified distance between the pair of binding holes is protruded from the punching shaft position on the bar side. There is also a desktop puncher that opens four binding holes at the same pitch for binding to a paper surface of a document or the like (see, for example, Patent Document 2).

[Problems to be solved by the invention]
However, each of the conventional desktop hole punches is configured to open at least a pair of binding holes for stacking and binding the document or the like on a sheet of one or more stacked documents.
[0006]
The present inventor has a cylinder capable of opening a second through hole having a desired inclination angle with respect to the first through hole opened on both side surfaces of the cylindrical paper tube on the other side surfaces of the cylindrical paper tube. I don't know the desk punch for the paper tube.
[0007]
By the way, the inventor of the present invention has incorporated a thin tube block having a desired length into which a paper is wound in a cylindrical shape, and a paper having a desired length in which the paper having an inner diameter into which the thin tube block for incorporation can be inserted is wound into a cylindrical shape. Insert the thin tube block for assembly into the hollow portion of the large tube block for assembly or the assembly hole opened in the side surface of the large tube block for assembly using at least the two types of blocks with the large tube block for assembly. For example, a three-dimensional creation assembling block production apparatus for producing the two types of blocks in the block set for assembling the three-dimensional creation 30 shown in FIG. A pair of support plates with holes open and a built-in paper take-up core shaft for winding the paper so as to be rotatable around the shaft hole and making the thin tube block for assembling, and the shaft hole being rotatable The thick cylinder block for assembling by winding and winding paper Invented a three-dimensional creative assembling block manufacturing apparatus comprising an assembly paper winding core shaft having an outer diameter larger than the outer diameter of the built-in paper winding core shaft to be manufactured (Japanese Patent Application 2002-2002). 303391). In carrying out the invention, a second through hole having a desired inclination angle with respect to the first through hole opened on both side surfaces of the cylindrical paper tube in which the paper is wound in a cylindrical shape is formed in another cylindrical paper tube. If you use a desktop puncher for cylindrical paper cylinders that can be opened on both sides, the mounting holes are inclined to the side of the large cylinder block for assembly made by the three-dimensional creative assembly block manufacturing device. It is possible to easily form a mounting hole for inserting a thin cylindrical block for mounting which becomes a corner.
