Description

  The present invention relates to a tape cutter that supports and cuts a pressure-sensitive adhesive tape roll on which a belt-shaped pressure-sensitive adhesive tape is wound, and particularly relates to a portable tape cutter formed so as to be light and easy to carry.

Conventionally, as a tape cutter, a shaft portion that rotatably supports an adhesive tape winding body, a case that supports the shaft portion and accommodates the adhesive tape winding body, and a cutter portion that cuts the drawn adhesive tape are provided. What is known.
As the tape cutter, there are known a large mounting tape cutter that is used by being placed on a desk or the like, and a small portable tape cutter that can be carried in a pocket or a bag.
In the mounting tape cutter, the case is formed to have a relatively large weight while the case is mainly formed to be able to accommodate an adhesive tape having a large winding diameter.
On the other hand, the portable tape cutter has a case that can mainly support an adhesive tape having a small winding diameter and is small and lightweight so that it can be easily carried.

Since the case has a weight, the mounting tape cutter can be cut by the cutter portion by pulling out the adhesive tape with one hand in a state where the mounting tape cutter is placed on a table or the like. However, since it is large and heavy, it is inconvenient to move and carry.
On the other hand, since the portable tape cutter is lightweight, it is easy to move and carry, but when in use, the portable tape cutter is held with one hand and the adhesive tape is pulled out with the other hand and cut. Therefore, it is necessary to use both hands at the time of use, and improvement in operability has been desired.

Therefore, a portable tape cutter that can be operated with one hand has been proposed. This portable tape cutter that can be operated with one hand includes a case that accommodates an adhesive tape roll, a cylinder that is rotatably supported by the case and can be fitted to the inner periphery of the adhesive tape roll, and the cylinder. A claw wheel provided at one end of the body, and one end engaged with the claw wheel, while the other end of the head protrudes from the case, and pressing the head disengages from the claw wheel. And a biasing means for biasing the rotation-preventing rod in a direction to engage the ratchet wheel is known (for example, Patent Documents). 1).
According to this prior art, when a pressure-sensitive adhesive tape wound body, which is so-called double-sided tape formed on both sides so that it can be bonded, is applied as the pressure-sensitive adhesive tape wound body, the top side of the double-sided tape is first bonded to the object to be bonded. Next, push the head of the detent rod to disengage the ratchet wheel, pull out the adhesive tape while moving the case in this state, and when this adhesive tape is pulled out a predetermined amount, The head is separated and the rotation of the cylindrical body and the adhesive tape winding body is restricted, and in this state, the case can be pulled up and the adhesive tape can be cut by the cutter portion.
As described above, since the adhesive tape is pulled out by moving the case after the adhesive tape is bonded to the object to be bonded, an operation with one hand is possible.
Japanese Patent Laid-Open No. 6-179561 (FIG. 1)

  However, in the portable tape cutter that enables the one-handed operation described above, a cylindrical body that is rotatable with respect to the case, a ratchet wheel that is integral with the cylindrical body, a rotation prevention rod that engages with the hook wheel, There is a problem that there is a risk that the number of parts is large and the cost is increased or the portability is deteriorated, such as an urging means for urging the rotation preventing rod in the engaging direction. In addition, when pulling out the adhesive tape with one-handed operation, it is essential to first bond the tip of the adhesive tape to the object to be bonded. For example, the tape is cut to a suitable length and used. It cannot be used without being glued to it, and is inconvenient.

  The present invention has been made paying attention to the conventional problems as described above, and is easy to carry, can be reduced in the number of parts, can be reduced in cost, and does not adhere the adhesive tape to the object to be bonded.

In the portable tape cutter of the present invention, in the case of two-hand operation, as is well known, the case is held with one hand, the adhesive tape is pulled out with the other hand, and then cut with the cutter part.
On the other hand, in the case of one-handed operation, first, the suction cup is sucked onto a smooth surface of a suction target such as a tabletop and is held in the suction target. Since the case is held by the suction cup in this way, the adhesive tape can be pulled out and cut without holding the case with the other hand, even if the case is compact and lightweight for portability. Can do. Further, in this case, the adhesive tape can be pulled out and cut by a necessary amount as appropriate, and in performing a one-hand operation, the drawing-out method is not limited and the usability is excellent.
In addition, since the case is mounted so as to be rotatable with respect to the rotation axis of the suction cup, the orientation of the case relative to the suction cup can be changed without removing the suction cup from the suction target even after the suction cup is held on the suction target such as a table. The adhesive tape can be pulled out in a direction that is easy to use.
Furthermore, the additional parts necessary to enable one-handed operation as described above are only suction cups, and the number of parts does not increase as in the prior art, and can be manufactured at low cost. , Portability is not deteriorated.
