Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive tape cutter, and more particularly to a so-called hand-type tape cutter capable of cutting an adhesive tape after it has been attached to an object while being housed.

[0002]

2. Description of the Related Art Conventionally, this kind of adhesive tape cutter is
After the adhesive tape was attached to the object, a cutting blade for cutting the adhesive tape was attached in the vicinity of the adhesive tape pressure roller by projecting and fixing. Therefore, after the adhesive tape is attached to the object, there is a problem that the protruding cutting blade comes into contact with the object and scratches it when the adhesive tape is cut.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide an adhesive tape cutter which does not damage an object when the adhesive tape is cut. To do.

[0004]

An adhesive tape cutter of the present invention is a cutting blade for attaching an adhesive tape pressure roller to a tape holder and projecting the adhesive tape in the vicinity of the pressure roller to cut the adhesive tape after attachment. The above object is achieved by attaching a cutting lever provided with a portion.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of the adhesive tape cutter of the present invention, and FIG. 2 is a bottom view of the same. In both figures,
Reference numeral 10 denotes a tape holder, which is composed of an adhesive tape housing portion 11 and an adhesive tape sticking operation portion 12 as in the conventional case.

An adhesive tape pressure roller 20 is rotatably attached to the adhesive tape attaching operation section 12.
Reference numeral 30 denotes a cutting lever, which is attached to the adhesive tape sticking operation unit 12 near the adhesive tape pressure roller 20.

The cutting lever 30 is composed of a substantially L-shaped bent plate-like body, and a cutting edge portion 31 protruding slightly outward is formed at the end of the adhesive tape pressure roller 20 side.
The bent portion 32 on the other end side is a pressing portion (power point) against the object to be attached. 33 is a control projection, which is a lever 3 for cutting
0, which is attached to the upper surface of No.
It is inserted and locked in.

Reference numeral 40 denotes a leaf spring, one end of which is attached to the adhesive tape attaching operation section 12 and the other end of which is free.
An elliptical hole 41 is formed in the leaf spring 40, and the cutting lever 30 is slightly slid (several millimeters) with the operation of the leaf spring 40 by inserting and locking the control projection 33. ing.

The cutting lever 30 has a fulcrum projection 50 attached to the leaf spring 40 and the adhesive tape attaching operation section 12.
And the cutting edge portion 3 while being biased by the leaf spring 40.
1 is placed in a state in which 1 is close to the adhesive tape crimping roller 20 but does not project to the outside thereof, and the bent portion 32 projects from the tape holder 10, and the cutting edge portion 31 of the adhesive tape crimping roller 20 is leveraged by leverage. The adhesive tape T is cut so as to project to the outside.

Next, an example of use of the adhesive tape cutter according to this embodiment will be described with reference to FIGS. First, as in the conventional case, the adhesive tape T is pulled out from the adhesive tape pull-out port 11a of the adhesive tape storage unit 11 to the adhesive tape pressure roller 20 of the adhesive tape sticking operation unit 12, and the tape holder 10 is held in that state, and the pressure roller concerned. The adhesive tape T is affixed by rotating 20 while contacting the affixing target P (FIGS. 3 and 4). Next, the bending portion 32 of the cutting lever 30 is pressed against the attachment target P against the bias of the leaf spring 40, and the tape holder 10 is raised at an appropriate angle (usually 30 to 90 °) and pulled. By the lever action of the cutting lever 30 with the fulcrum protrusion 50 as a fulcrum, the cutting blade portion 31 (point of action) in the opposite direction of the bent portion 32 (power point) is projected to the outside of the adhesive tape pressure roller 20. The adhesive tape T is cut (FIGS. 5 and 6). After cutting, if the bent portion 32 is separated from the sticking target P, the leaf spring 40
Due to the restoring force, the cutting lever 30 receives the leverage in the opposite direction, and the cutting blade portion 31 returns to the inside of the adhesive tape pressure bonding roller 20. When the cutting edge portion 31 projects or returns, the elliptical hole 4
By the action of 1 and the control projection 33, the lever 3 for cutting
0 slides slightly (FIGS. 4 and 6), so that the cutting edge portion 31 can be smoothly projected and returned, and
Due to the biasing force of the leaf spring 40, the proximity of the cutting blade portion 31 and the pressure bonding roller 20 is maintained during the non-levering action, so that the end of the adhesive tape T after cutting has the cutting blade portion 31 and the pressure bonding roller 20.
It can be stuck and cut continuously without getting in between.

[0012]

According to the present invention, since the cutting edge portion 31 does not project to the outside of the adhesive tape pressure roller 20 during the operation of attaching the adhesive tape T, the adhesive tape T is not damaged at all. Can be attached. Further, when the adhesive tape T is cut, the tape holder 10 is started up so that the cutting edge portion 31 is projected to the outside of the adhesive tape pressure roller 20 by the leverage, and the cutting lever 3 is cut.
Since only the bent portion 32 of 0 is brought into contact with the sticking object P, the sticking object P is not damaged at all.
