TECHNICAL FIELD The present invention relates to a tape cutter,
In particular, the present invention relates to a tape cutter to which an adhesive tape used for a packing operation is attached and the adhesive tape can be fed and cut in a hand-held state.

[0002]

Generally, in a packing operation using an adhesive tape, the adhesive tape is repeatedly fed and cut from an adhesive tape roll. Conventionally, a hand-held tape cutter to which an adhesive tape roll is attached has been used so that cutting and cutting can be easily performed. As shown in FIG. 6, such a hand-held tape cutter 1
Is different from the desktop type bladed tape holder as office supplies, and the plate material is formed in an arc shape corresponding to the inner peripheral shape of the core so that the core of the adhesive tape roll can be rotatably mounted. The holder body 2, a feeding part 3 located forward of the holder body 2 in the sticking tape feeding direction X, a cutting part 4 located further forward from the feeding part 3, and the holder body 2. And a cover 5 which is rotatably provided so as to cover the cover 5 and has a gentle curved shape. The feeding unit 3 is provided with a pair of rollers 3a and 3b that are rotatably supported on each other and arranged in the adhesive tape feeding direction X so as to open a required gap 3c between the rollers. As shown in the drawing, one of the rollers 3a, which is located on the front side in the adhesive tape feeding direction X in the feeding portion 3, has a front edge portion of the bent and raised portion 2a on the side edge of the holder body 2 as shown in the drawing. And a front side of the vertical plate member 6 in the sticking tape feeding direction X is bent so as to support both ends of the one roller 3a, and the one roller 3a is freely rotatable on the bent portion 6a. And the other roller 3 positioned on the rear side (that is, on the holder body 2 side) in the adhesive tape feeding direction X.
b, it is rotatably supported by the vertical plate member 6 in a cantilever state.

[0003] The cutting section 4 is provided with a cutting blade 7 for cutting the adhesive tape fed from the adhesive tape roll mounted on the holder body 2 through the gap between the rollers 3a and 3b in the feeding section 3, and the bending section 6a. It is attached to the front inclined plate 6b constituted by the above while using the holding plate 8. The cover 5 is rotatably provided so as to be pivotally supported by a rear portion of the bent portion 6a so as to be able to jump upward from a position covered by the holder body 2 as described above. The tape cutter 1 can be held by hand while holding the hand 2 and the cover 5, and the adhesive tape roll mounted on the holder body 2 is sandwiched between the holder body 2 and the cover 5 to rotate the adhesive tape roll. The entire tape cutter is tilted forward while the rotation of the adhesive tape roll is stopped, and the cut portion 4 is attached to the fed adhesive tape.
Can be applied to cut the adhesive tape.

In the above-mentioned tape cutter, as described above, between the two rollers, for example, because a new adhesive tape roll is mounted so that the drawing end of the adhesive tape can be easily passed through the feeding portion. A gap is provided. However, when the tape cutter has been used, or when the tape is temporarily released after cutting the adhesive tape, the adhesive tape roll becomes easy to rotate freely, and the adhesive tape that has been fed out However, due to the rotation, the adhesive tape is easily pulled back through the gap, and the cut edge of the adhesive tape is attached to the adhesive tape roll itself. Once the cut end of the adhesive tape is once adhered to the adhesive tape roll, it becomes difficult to find the cut end, and the cut end cannot be easily peeled off. In order to prevent this, it is necessary to fold the cut end of the adhesive tape to provide a fold that does not stick the tape. In view of the above circumstances, it is an object of the present invention to prevent the adhesive tape that has been fed out from being pulled back in a normal use state, and to improve the usability of a tape cutter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the embodiments shown in FIGS. 6 and 7 are denoted by the same reference numerals and the description thereof is omitted. In the feeding section 3 of the tape cutter 1 of the present invention, a pair of rollers 9 and 10 are arranged in the sticking tape feeding direction X in the same manner as in the conventional example. And
One of the rollers 9 located on the front side (the cutting section 4 side) in the adhesive tape feeding direction X is not directly attached to the bent section 6a, and as shown in FIGS. On the rear side of the bent portion 6a, the roller holder 11 is rotatably supported coaxially with the rotation center axis a of the cover 5 and rotatable downward from the lower surface side of the front inclined plate 6b of the bent portion 6a. Attached. Further, an urging means 12 composed of a spring or the like is arranged between the roller presser 11 and the front inclined plate 6b, and the urging force from the urging means 12 is transmitted through the roller presser 11 by The one roller 9 is urged toward the other roller 10, and unless one roller 9 is positively rotated to the front inclined plate 6 b side, the other roller 9 is pressed. Abuts on the other roller 10, and holds the fed adhesive tape while allowing it to be fed by both rollers 9, 10.

The other roller 10 is a roller on the side where the adhesive surface of the adhesive tape to be fed comes into contact, and the peripheral surface 10a of the other roller 10 is knurled so that the adhesive tape is firmly adhered. Thus, the adhesive tape is adhered with a certain degree of adhesive force so as not to hinder the operation of feeding the adhesive tape. Further, the other roller 10 is provided with a reversing prevention means 13 made of a ratchet or the like, and is regulated so that the other roller 10 does not rotate in the opposite direction to the rotation direction in which the adhesive tape is fed. And A pair of rollers 9 and 10 sandwich and support the adhesive tape fed out as described above, and when the adhesive tape is further fed, both rollers 9 and 10 rotate in the direction of feeding the adhesive tape. (Note that one roller can rotate in either direction). Then, even when the adhesive tape roll slightly rotates, for example, when the hand is released from the tape cutter, the applied adhesive tape is nipped by the pair of rollers 9 and 10, and the other roller 10 is not inverted. From that
The fed-out adhesive tape is securely held without coming off from between the rollers, thereby preventing the cut end from being attached to the adhesive tape roll as described above.

Further, in the feeding portion 3, a roller holder 11 to which the one roller 9 is attached is provided.
Is provided with a lever 14 projecting laterally as a separating means, and the lever 14 is lifted upward with the finger as a finger, so that the roller holder 11 rotates to the front inclined plate 6b side. Roller 9 is replaced with the other roller 10
