That is, as shown in FIG. 3, the swing frame 15 has a pair of vertically elongated rectangular plate-shaped left and right side walls 16 and 16 arranged at intervals in the width direction, and a pivot 17 between the lower portions of both. As shown in FIG. 2, both ends 17a, 17a of the pivot shaft 17 are connected to each other by extending the extension walls 14, 1 respectively.
It is rotatably supported in bearing holes 18, 18 provided in the lower part of 4.

Further, the swing frame 15 has a rectangular plate-shaped tape adhesive plate 19 fixedly attached to the front portion of the upper end thereof, and a temporary tape fixing roller 20 rotatably attached to the rear portion of the upper end thereof. .

With this structure, the swing frame 15, the tape adhesive plate 19 attached to the swing frame 15 and the tape temporary fixing roller 20 are integrally formed around the axis of the pivot shaft 17,
It can swing back and forth.

However, the upper extension walls 14, 1 centering around the pivot 17
Both ends 22a, 22 of the rocking angle regulating shaft 22 installed between the left and right side walls 16, 16 of the rocking frame 15 in the arcuate long holes 21, 21 provided in
By slidably inserting a, swing frame 15
The swing amount of is regulated.

Further, as shown in FIG. 2, the swing frame 15
A tension coil spring 23 as an elastic means is provided between the lowermost part of the and the inner wall of the front part of the main body frame 10. Therefore, by the spring force of the tension coil spring 23, the swing frame 15 can be set to the vertical position shown by the solid line in FIG. 1 when not in use, and the adhesive tape T can be pulled out from the adhesive tape reel 12a. When using for cutting, the forward tilted position can be set, as will be described later.

Next, a tape cutting operation by the adhesive tape cutter A having the above structure will be described.

When a portion of the adhesive tape T protruding from the tape adhesive plate 19 is taken with a finger and the adhesive tape T is pulled toward the cutting blade 13, the adhesive tape T is located at a position slightly rearward of the tape adhesive plate 19. While being guided to the temporary tape fixing roller 20 at the same time, the swing frame 15 stops near the cutting blade 13 at the same time as the length to be cut, and the adhesive tape T is cut while being attached to the tape adhesive plate 19 again.

In the cutting operation, the tension force is applied to the adhesive tape T by the tension coil spring 23, so that the adhesive tape T can be easily and reliably cut.

Immediately after cutting, the tip of the adhesive tape T is
Although remaining on the cutting blade 13, when the swinging frame 15 swings backward by the spring force of the tension coil spring 23 and returns to the original position, the tip of the adhesive tape T also moves in the same direction, Away from 13.

Further, since there is a gap between the cutting blade 13 and the tape adhesive plate 19, at the time when the tip of the adhesive tape T is separated from the cutting blade 13 after cutting, the portion which is behind the tip of the adhesive tape T. Are adhered to the tape temporary fixing roller 20 and the tape adhesive plate 19, respectively, and the tip of the adhesive tape T is in a state in which it is projected a few cm ahead of the tape adhesive plate 19, that is, in a cueed state.

Therefore, in the next tape cutting operation,
The adhesive tape T can be pulled out by picking the cue portion.

Further, in the above-mentioned work of cutting the adhesive tape T, since the restoring force of the tension coil spring 23 is considerably large, the adhesive tape T may be separated from the swing frame 15 only by the tape adhesive plate 19. Therefore, in this embodiment, a tape temporary fixing roller 20 is provided in addition to the tape adhesive plate 19.

On the other hand, the tape adhesive plate 19 has a structure in which the head of the adhesive tape T is substantially horizontal so that the adhesive tape T
It is also used to facilitate the withdrawal of.

FIG. 4 shows a modified example of the adhesive tape cutter A having the above structure.

As shown, the adhesive tape cutter A
When the swing frame 15 is attached to the main body frame 10 so as to be swingable in the front-rear direction, the vertical relationship between the pivot shaft 17 and the swing angle regulation shaft 22 is reversed. Then, between the swing angle regulation shaft 22 and the front inner wall of the main body frame 10,
A tension coil spring 23 is installed. Therefore, the swing frame 15 is moved by the spring force of the tension coil spring 23.
When not used, the vertical position shown in FIG. 4 can be taken, and when the adhesive tape T is pulled out from the adhesive tape reel 12a and cut, it can be taken to the forward tilted position.

Further, in this modified example, a flat plate-like safety cover 24 is disposed on the back surface side of the cutting blade 13 in a substantially abutting state, and the safety cover 24 is made of an elastic curved steel plate. It is connected to the swing angle regulation shaft 22 by an arm 25.

As shown in FIG. 4, the safety cover 24 has its upper end protruding above the upper cutting surface of the cutting blade 13 in the unused state.

Therefore, it is possible to reliably prevent a finger or the like from accidentally touching the cutting blade 13 and injuring it.

On the other hand, as described above, since the safety cover 24 is connected to the swing frame 15 via the steel plate arm 25, the safety cover 24 also swings in conjunction with the forward tilting motion of the swing frame 15. It moves downward together with the moving frame 15 and, as a result, the cutting blade only at the moment of cutting the adhesive tape T.
13 will be exposed. Therefore, while ensuring sufficient safety, the pull-out end of the adhesive tape T can be easily pulled out and cut.

Although the present invention has been specifically described with reference to the embodiments shown in the accompanying drawings, the present invention is not limited to the structures described in the embodiments. For example, the following structures are provided. Are also included in the present invention.

As long as the tape adhesive plate 19 and the temporary tape fixing roller 20 are provided on the upper part with a space in the front-rear direction, the swing frame 15 does not swing in the front-back direction but moves in the up-down direction. The same tape cutting and tape cueing effect can also be obtained by moving vertically.

Further, as shown in FIG. 3, by providing a lateral groove on the surface of the temporary tape fixing roller 20, it is possible to reduce the resistance of the adhesive tape T when the adhesive tape T is pulled out.

The safety of the pressure-sensitive adhesive tape cutter A can be further improved by giving the safety cover 24 a rounded top or sticking elastic rubber to the top.
