  The tape applicator disclosed in Patent Document 1 includes a holding unit that holds an adhesive tape so that the adhesive tape can be unwound freely, a pressing unit that presses the adhesive surface of the adhesive tape that is fed out of the holding unit against the surface to be applied, and a pressing unit to which the tape is applied. And a cutting section for cutting the adhesive tape attached to the surface. Furthermore, the receiving part which receives the adhesive surface of an adhesive tape is provided between the press part and the holding | maintenance part so that the front-end | tip of an adhesive tape may be located under a press part after the cutting | disconnection of an adhesive tape.

  According to the configuration of Patent Document 1, since there is only one receiving portion that receives the adhesive surface of the adhesive tape after cutting, depending on the posture of the adhesive tape, the adhesive surface of the adhesive tape contacts the receiving portion. There are things that do not.

  In addition, the adhesive tape is held in the holding part, and the adhesive tape is fed out so that the tip of the adhesive tape is located below the pressing part, and then the adhesive surface of the adhesive tape is brought into contact with the receiving part to change its position. Although it will be maintained, since only one receiving part is provided, the adhesive tape may come off unexpectedly from the receiving part.

  In this way, if the adhesive surface of the adhesive tape does not come into contact with the receiving part after the adhesive tape has been cut, or if the adhesive tape comes off unexpectedly from the receiving part, the adhesive tape moves to the holding part side, and the tip of the adhesive tape The part is not located below the pressing part. As a result, it is troublesome that the next sticking operation of the adhesive tape cannot be performed unless the tip of the adhesive tape is positioned below the pressing portion, and there is room for improvement.

  Therefore, the present invention has been made in view of such circumstances, and provides a tape applicator that can always position the front end of an adhesive tape below a pressing portion.

  The tape applicator according to the present invention includes a holding unit that holds a roll-shaped adhesive tape having an adhesive layer on one side so that the roll can be drawn out, and an adhesive side of the adhesive tape that is drawn out from the holding unit.

Moreover, the trouble that the adhesive tape 1 slackened after cutting of the adhesive tape 1 moves in the left-right direction and does not contact the receiving surfaces 7A, 8A of the receiving portions 7, 8 can be prevented. Furthermore, since the adhesive tape 1 is in contact with the two receiving portions 7 and 8, it is possible to prevent a trouble that the adhesive tape 1 is unexpectedly detached from the receiving portions 7 and 8.

  When the sticking of the adhesive tape 1 is completed, the blade applicator A is further tilted forward from the state shown in FIG. 4 and 5 (a)). From this state, by tilting the tape applicator A to one side in the left-right direction (right side as viewed from the front in FIG. 5B), the one side in the left-right direction (right side in FIG. 5B) of the adhesive tape 1 is moved. Disconnect. Thereafter, the tape applicator A is tilted to the other side in the left-right direction opposite to the above (left side as viewed from the front in FIG. 5C), thereby causing the other side of the adhesive tape 1 in the left-right direction (FIG. 5C). Then, the left part) is cut, and the application of the adhesive tape 1 is finished.

  When cutting is completed as described above, the pressure-sensitive adhesive tape 1 is loosened downward due to its own weight, and the pressure-sensitive adhesive surface 1A of the loosened pressure-sensitive adhesive tape 1 is in contact with the receiving surfaces 7A and 8A of the receiving portions 7 and 8 and pasted. It will be in the attached state. In this state, as shown in FIG. 1, the distal end portion 1 </ b> S of the cut adhesive tape 1 can be reliably positioned below the pressing portion 3, and the next adhesive tape 1 is attached to the adherend surface F. Work can be done quickly. And since the two receiving parts 7 and 8 are provided in the attitude | position substantially orthogonal to the adhesive surface 1A of the adhesive tape 1, the receiving parts 7 and 8 can be reliably applied to the adhesive surface 1A of the adhesive tape 1. FIG. There are advantages you can do. Further, as described above, the casing 5 is provided with the opening 5 a for exposing a part of the adhesive tape 1 to the outside of the casing 5. For this reason, if the adhesive tape 1 after being cut at the cutting portion 4 does not come into contact with the receiving surfaces 7A and 8A of the receiving portions 7 and 8, the tip portion 1S of the adhesive tape 1 enters the inside of the casing 5. However, by rotating the adhesive tape 1 through the opening 5a, the front end 1S of the adhesive tape 1 can be fed out and forcibly moved to below the pressing portion 3.

  In addition, by tilting the tape applicator A to either the left or right side and cutting the left and right sides of the adhesive tape 1, the tape applicator A is tilted to the other side and the left and right sides of the adhesive tape 1 are cut. There is also an advantage that the adhesive tape 1 can be reliably cut as compared with the configuration in which the adhesive tape 1 is cut all at once.
