BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, which is a perspective view, an adhesive tape support base 2 according to a first embodiment of the present invention is housed in a frame-shaped main body 4 and an adhesive tape T. Roll R
An inner frame 8 having a roll support shaft 6 for mounting (see FIG. 3) on one side. The inner frame 8 is further integrally formed with a tape adhered member 12 having an adhered surface 10 extending in the width direction of the adhesive tape to be mounted, on the side far from the roll support shaft 6. The inner frame 8 is rotatably attached to the main body 4 via a rotary shaft 13 provided at the lower end of the tape adhered member 12. The main body 4 further has a movable surface 1 to be adhered, which extends farther from the roll support shaft 6 in parallel to the surface 10 to be adhered and in the width direction of the adhesive tape.
A movable tape adhered member 16 having a number 4 is provided, and the movable tape adhered member 16 is rotatably attached to the main body 4 via a pivot shaft 18 provided at the lower end. A cutter 20 is attached to the side surface of the movable tape adhered member 16 on the side far from the roll support shaft 6.

As shown in FIG. 2, which is a longitudinal sectional view of the adhesive tape support base shown in FIG. 1, the surface 10 to be adhered and the movable surface 14 to be adhered are located at substantially the same height and adjacent to each other. , Tape adhesive member 12 and movable tape adhesive member 16
And are located in adjacent positions. The blade of the cutter 20 is
The movable plate-shaped portion 16 is positioned slightly outward from the side surface of the movable plate-shaped portion 16 remote from the roll support shaft 6 and slightly below the movable adhered surface 14. A slightly vertically long slot 22 is formed on both side surfaces of the inner frame 8, and a support shaft 24 is attached to the inner side surface of the main body 4 through the slot 22. Further, a through hole 26 is formed in the tape adhered member 12 of the inner frame 8, one end of the spring 28 is passed through the support shaft 24, and the other end is passed through the through hole 26, so that the inner frame of the movable tape adhered member 16 is formed. It is attached to the protrusion on the surface on the 8 side. Spring 28
Is the movable tape adhesive member 16 and the tape adhesive member 12
In addition, the movable tape adhered member 16 pushes the tape adhered member 12 to move the inner frame 8 to the lowermost position in the main body 4, that is, the lower end of the inner frame 8 contacts the bottom of the main body 4. Hold in contact position.

FIG. 3 is a vertical sectional view similar to FIG. 2, showing a state where the adhesive tape T is pulled out from the roll R of the adhesive tape T installed on the roll support shaft 6. On the surface of the tape adhered member 12 facing the movable tape adhered member 16,
As shown in FIG. 3, a protrusion 32 is formed, and a protrusion 36 having an inclined surface 34 is formed on the surface of the movable tape adhered member 16 facing the tape adhered member 12, and the protrusion 32 is It engages with the inclined surface 34 of the protrusion 36. The elastic resistance of the spring 28 is smaller than the pulling force when pulling out the adhesive tape T from the roll R, and when pulling out the adhesive tape T from the roll R, the inner frame 8 is rotated by the pulling force applied to the adhesive tape T. It rotates with respect to the main body 4 around the center 13, and the tape adhered member 12 also rotates accordingly. By this rotation, the protrusion 32 of the tape adhered member 12 is formed in an arc shape, that is, the movable tape adhered member 16
The protrusion 36 moves downward along the inclined surface 34. As a result, the movable tape adhered member 16 rotates about the pivot shaft 18, and the tape adhered member 12 and the movable tape adhered member 16 are positioned at the separated position,
The adhered surface 14 is the adhered surface 10 of the tape adhered member 12.
Keep away from When the lower end portion 38 of the tape adhered member 12 contacts the pivot shaft 18, the inner frame 8 is prevented from rotating. As a result, the protrusion 32 does not push the inclined surface 34 of the protrusion 36 any more, and the rotation of the movable tape adhered member 16 also stops. Therefore, even if the adhesive tape T is further pulled out, the movable tape adhered member 16 does not rotate. The slot 22
Is formed vertically long so that the support shaft 24 attached to the main body 4 does not hinder the rotation while the inner frame 8 rotates with respect to the main body 4.

The ridge lines of the adhered surfaces 10 and 14 are different from the adhered surface 10 when the adhered surface 10 and the adhered surface 14 are displaced from the separated position to the adjacent position while the adhesive tape T is temporarily adhered. The adhesive tape extending between 14 and
And 14 are inclined and curved so that the adhesive tape T is directed in a direction where it is not sandwiched. That is, when the ridge lines of the adhered surface 10 and the adhered surface 14 are sequentially A, B, C, and D in the pull-out direction of the adhesive tape T, AB and CD are convexly curved outward and pass through the ridge AB. The extended surface of (1) passes above the adhered surface 14, and the extended surface of the surface passing through the ridge CD passes above the adhered surface 10. Further, the blade E of the cutter 20 is arranged below the ridge D in order to cut the adhesive tape pulled out from the roll. With this configuration,
When the adhesive tape T is cut, it can be ensured that the adhesive tape T adheres to the adherend surfaces 10 and 14 with an appropriate adhesive force.

As shown in FIG. 4, which is a perspective view of the cutting portion after the adhesive tape is cut, once the adhesive tape T is cut, the inner frame 8 is no longer given a tensile force, and the inner frame 8 is no longer applied.
Returns to the lowest position in the main body 4 by its own weight, and the movable tape adhered member 16 is pulled back to a position adjacent to the tape adhered member 12 by the spring 28. During this time, the adhesive tape T
Remains attached to the adhered surfaces 10 and 14, and the adhesive tapes T located between the adhered surfaces 10 and 14 are brought close to each other and folded in two with the adhesive surface inside and looped. The folded portion 40 is formed. Therefore,
Adhesive surface 1 shown in FIG. 3 when the adhesive tape T is pulled out
The distance between 0 and the surface to be adhered 14 is such that the loop-shaped folded-back portion 40 formed is of a size suitable for being picked by a finger. In addition, this distance is
When 4 moves to the adjacent position, the adherend surfaces 10 and 1
The adhesive tape T extending between 4 and 4 is too long and sags downward,
The distance is set so that it is not sandwiched between the two.

When the adhesive tape T is cut again, the adhesive tape T may be pulled out by a predetermined length while holding the folded portion 40 and cut by the cutter 20. According to this embodiment, after the adhesive tape T is cut, the folded-back portion 40 is formed at the end of the adhesive tape T left on the adhesive tape support base 2, so that the adhesive tape T can be pulled out next time. It is useful as the folded-back portion 40, and it is possible to prevent it from being soiled by being held by the adhesive surface of the adhesive tape. Further, since the folded-back portion 40 is formed at the end portion of the adhesive tape T cut by a necessary amount, the folded-back portion 4 is formed even if it is once attached to an article.
It can be easily peeled from the article by pulling 0. Further, according to the present embodiment, the adhesive tape T is simply
When the adhesive tape T is pulled out, the inner frame 8 pivotally attached to the main body 4 is rotationally moved by the pulling force when the adhesive tape T is pulled out, and the movement causes the protruding portion 36 having the protruding portion 32 and the inclined surface 34. The movable tape adhered member 16 is moved via
Further, since the spring 28 pulls back to the adjacent position, the surface to be adhered 14 can be moved away from the position adjacent to the surface to be adhered 10 or returned to the adjacent position by a simple mechanism.
