Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a paper knife with a writing function and a paper clipping function.

"Prior Art" A paper knife can be used to cut paper by applying it to the fold line of folded paper, and is widely used in offices and the like to cut paper.

``The problem that the invention aims to solve'' By the way, conventional paper knives like this one can cut paper, but they have no other purpose than that.

This invention was made in view of the above circumstances, and the purpose is to provide a paper knife having a writing function and a paper clipping function.

"Means for Solving Problems" In this invention, in a paper knife equipped with a blade and a flat grip, a ballpoint pen accommodating hole is provided in the grip, and the flat ballpoint pen grip is inserted into the ballpoint pen accommodating hole. The ballpoint pen shaft is housed parallel to the gripping part and is rotatable or detachable from the gripping part, and a ballpoint pen shaft is provided in the ballpoint pen gripping body with its tip protruding, and further parallel to the ballpoint pen gripping body. The paper holding plate is provided in a cantilevered manner.

According to this invention, in addition to the paper cutting function using the blade, it is possible to perform the writing function using a ballpoint pen and the paper pinching function using a paper clamping plate or the like.

"Example" This invention will be described in detail below with reference to an example.

Figures 1 to 3 show a paper knife in an embodiment of this invention, Figures 4 to 7 show the blade and grip part of this paper knife, and Figures 8 to
FIG. 11 shows the ballpoint pen portion of this paper knife.

This paper knife includes a blade portion 11 and a flat grip portion 12. The gripping portion 12 is formed with a ballpoint pen gripping body accommodating hole 13 and a ballpoint pen shaft tip accommodating hole 14 with one end open. Linear engagement protrusions 15 are formed on both wall surfaces of the ballpoint pen grip housing hole 13, and a pin 16 is formed in the center of the engagement protrusions 15.

A flat ballpoint pen holder 21 is rotatably accommodated in the ballpoint pen holder accommodation hole 13 . That is, since the pin 16 is rotatably fitted into the recesses 22 formed on both wall surfaces of the ballpoint pen holder 21, the ballpoint pen holder 21 is rotatably accommodated in the ballpoint pen holder accommodation hole 13. There is. The thickness of the ballpoint pen gripping body 21 is approximately the same as the thickness of the gripping part 12. Linear engagement grooves 23 are formed on both wall surfaces of the ballpoint pen holder 21 . A ballpoint pen shaft 24 is provided within the ballpoint pen holder 21 with its tip protruding. Further, a paper holding plate 25 is provided in parallel with the ballpoint pen holding body 21 in a cantilevered manner.

When using this paper knife as a ballpoint pen, hold the ballpoint pen grip 21 etc. in the state shown in FIGS. 1 and 2 with the pin 16 at the center.
It is rotated 180 degrees to cause the tip of the ballpoint pen shaft 24 to protrude to the rear of the grip portion 12, as shown in FIG. When rotating the ballpoint pen grip 21 etc.,
The engagement protrusion 15 is removed from the engagement groove 23, and the grip portion 12
The portions on both sides of the ballpoint pen holder accommodation hole 13 expand appropriately against its elasticity, thereby allowing the ballpoint pen holder 21 and the like to rotate. When the ballpoint pen holder 21 or the like is rotated 180 degrees, the parts of the gripping part 12 on both sides of the ballpoint pen holder accommodation hole 13 return to their original states due to their elasticity, and the engagement protrusion 15 engages with the engagement groove 23 again. engage. Therefore, this paper knife can be used as a ballpoint pen in a stable state.

When using this paper knife as a paper scissors, rotate the ballpoint pen grip 21 etc. in the state of use as a ballpoint pen by 180 degrees, and as shown in FIGS. 1 and 2, the tip of the ballpoint pen shaft 24 The shaft tip is accommodated in the shaft tip accommodation hole 14.
In this state, paper (not shown) can be held between the gripping portion 12 and the ballpoint pen gripping body 21 and the elastic paper holding plate 25, and the engagement protrusion 15 is engaged with the engagement groove 23. This allows the paper knife to be used stably as a paper scissors.

When using this paper knife for its intended purpose, if it is placed in the state shown in FIGS. 1 and 2, the tip of the ballpoint pen shaft 24 will not get in the way, and the engagement protrusion 15 will be in the engagement groove. 23, so it can be used in a stable state.

In addition, in the above embodiment, the ballpoint pen grip 21
is rotatably attached to the grip part 12, but the present invention is not limited to this. For example, the pin 16 may be omitted and the ballpoint pen grip 21 can be freely inserted and removed from the grip part 12 in the left and right direction in FIG. , grip part 1
The ballpoint pen holder 21 may be held by the elastic action of the portions on both sides of the second ballpoint pen holder accommodation hole 13.

``Effects of the invention'' As explained above, according to this invention, in addition to the paper cutting function, it is possible to perform the writing function with a ballpoint pen and the paper clamping function with a paper clamping plate, etc., increasing the number of uses and adding value. can be increased.
