Third Embodiment FIG. 11 is a schematic cross-sectional view showing the entire third embodiment of a double-sided tape dispenser according to the present invention.

  In the third embodiment, even when the diameter changes depending on the amount of the release paper 2 wound up by the release paper holder 12, a predetermined amount of the double-sided tape 1A is pulled out, and the double-sided pressure-sensitive adhesive layer 3 having a predetermined length is applied to the surface 7 to be adhered. This is the case when pasting is possible.

  That is, the double-sided tape dispenser of the third embodiment is in contact with the release paper 2 between the support member 14 and the release paper holder 12 in the double-sided tape dispenser of the second embodiment, as shown in FIG. A rotation-adjustable roller 40 for adjusting the tape movement amount is disposed, and a rotation stop for which an elastic force is urged on a rotation shaft 40a of the roller 40 in a direction opposite to the rotation direction of the roller 40 by a spring member (not shown). The locking claw 41 is mounted so that the locking claw 41 can be engaged with a fourth gear 13 d provided on the release paper holder 12. By comprising in this way, even when a diameter changes with the quantity of the release paper 2 which the release paper holding body 12 winds up, a fixed amount of double-sided tape 1A can be pulled out, and the double-sided adhesive layer 3 of predetermined length can be pulled out. It can be attached to the surface 7 to be attached.

  In the double-sided tape dispenser of the third embodiment, the double-sided tape holder 11 is fitted to the rotating shaft portion 11a with appropriate friction, and the release paper holding body 12 is fitted to the rotating shaft portion 12a with appropriate friction. When the excessive force is applied in the pulling-out direction of the double-sided tape 1 and the winding-up direction of the release paper 2, it slips. In this case, as shown in FIG. 11, the rotational frictional force of the double-sided tape holder 11 is increased by making the rotary shaft part 12 a of the release paper holder 12 larger than the diameter of the rotary shaft part 11 a of the double-sided tape holder 11. On the other hand, the rotational frictional force of the release paper holder 12 is increased. Thereby, an excessive force is applied to the double-sided tape 1 </ b> A in a tension state between the double-sided tape holder 11 and the release paper holder 12 in the drawing direction of the double-sided tape 1 </ b> A and the winding direction of the release paper holder 12. Even so, since the double-sided tape holder 11 rotates before the release paper holder 12, there is no possibility of the double-sided tape 1A being cut.

  Further, when the first gear 13a of the double-sided tape holder 11 and the second gear 13b of the release paper holder 12 are engaged with each other, the release paper 2 is taken up and the double-sided tape 1 is pulled out, The gap of the feed amount is adjusted by making the double-sided tape holder 11 and the first gear 13a of the holder 11 have a slip structure so that the pull-out amount (feed amount) is smaller than the winding amount of the release paper 2. Therefore, the slack of the double-sided tape 1 can be prevented.

  In addition, since the release paper holder 12 has a slip structure, and the gap of the drawing amount (feed amount) of the double-sided tape 1 can be adjusted by the slip of the double-sided tape holder 11, the use of the double-sided tape dispenser is started. The pull-out amount (feed amount) of the double-sided tape 1 at the end of use can be made constant.
