取付けである。Below, one embodiment of the present invention will be explained in detail based on the drawings. In FIGS. 1 to 3, 1 is a drum 2.
A case body including a housing portion 1a rotatably supporting the
A bundle of adhesive tape 3 can be fitted onto the drum 2, and a cutter 4 is attached to one side edge 1b of the case body 1, which can cut the drawn-out adhesive tape 3 by pressing it against the drum 2. .

５は前記ドラム２の支持軸で、該支持軸５０両端は前記
収容部１ａの両内側壁に粘着テープ３の引出し方向と同

して設けられている。Reference numeral 5 denotes a support shaft of the drum 2, and both ends of the support shaft 50 rotate and move into bearing grooves 1c formed horizontally in the same direction as the direction in which the adhesive tape 3 is pulled out on both inner walls of the housing portion 1a. It is freely fitted into the bearing groove 1c in the drawing.
Since the adhesive tape 3 is normally pulled out obliquely upward when the tape is pulled out, it is provided with a slight inclination in accordance with the direction in which the tape 3 is pulled out.

また、前記の支持軸５は棒磁石によって形成され、更に
前記軸受溝１ｃの一端内部、具体的には粘着テープ３が
引出される方向と同じ側の端部内には、嵌込１れる軸５

に移動する。Therefore, as shown in FIG. 3, when the adhesive tape 3 attached to the cutter 4 is peeled off and the tension on the tape 3 is released, the support shaft 5 receives the repulsion force of the magnets 5 a and 5 b and moves in the same direction. As shown in the figure, the drum 2 moves to the other end (the left end in the figure) of the bearing groove 1c, and the drum 2 also moves together with the adhesive tape 3.

なお、上述した磁石５ａ 、５ｂの磁力作用を使わずに
、スプリングの弾発作用によって支持軸５を反発移動せ
しめるように構成してもよい。It should be noted that the support shaft 5 may be configured to be moved repulsively by the elastic action of a spring without using the magnetic force of the magnets 5a and 5b described above.

次に６・・・・は前記ドラム２の一側面に円周方向に等
間隔を置いて突設した係止突起で、これ等各突起６・・
・・の間隔が前記粘着テープ３の引出し量を決定する。Next, 6... are locking protrusions protruding from one side of the drum 2 at equal intervals in the circumferential direction, and each of these protrusions 6...
The distance between... determines the amount by which the adhesive tape 3 is pulled out.

７内の任意の位置に固定することができる。Reference numeral 7 denotes a horizontally long adjustment groove bored approximately horizontally in one side wall of the case body 1 so as to face the one side surface of the drum 2 on which the locking protrusion 6 is protruded, and 8 denotes the groove γ. The piece body 8 is movably fitted into the body, and a suction collar 8a and a screw shaft 8b are provided at the inner and outer ends of the piece body 8, respectively, and when the fixed dial 9 screwed onto the screw shaft 8b is tightened, Since the suction collar 8a and the fixed dial 9 sandwich the side wall of the case body 1 in which the adjustment groove 7 is formed from both sides, the piece body 8 is fixed at any position within the adjustment groove 7 as shown in FIG. I can do it.

及び粘着テープ３の引出しが停止される。10 is a locking piece protruding from the inner end surface of the piece body 8;
This locking piece 10 is a locking protrusion 6 provided on the drum 2.
When the drum 2 is rotated by pulling out the adhesive tape 3 and any of the locking protrusions 6 touch the locking pieces 10, the drum 20 rotates and the adhesive is removed. The tape 3 is stopped from being drawn out.

１１は前記係止片１０の一側縁、具体的には前記支持軸

できない構成となっている。Reference numeral 11 denotes a control piece attached via a hinge portion 11a to one side edge of the locking piece 10, specifically, the edge on the same side as the repulsive movement direction of the support shaft 5, and the tip side is attached to the opposite side of the drum 2. The hinge portion 11a hangs diagonally toward the rotation direction, and the hinge portion 11a can rotate the entire control piece 11 relative to the locking piece 10 only in the forward rotation direction of the drum 2, that is, in the direction of pulling out the adhesive tape 3, and It is configured such that it cannot rotate in the second reverse rotation direction (inclination direction of the control piece).

本考案は以上述べた如き構成であるから、第１図に示す

る。Since the present invention has the above-described configuration, when the tape 3 is peeled off from the cutter 4 in order to pull out the adhesive tape 3 from the state shown in FIG. The support shaft 5 of the drum 2 moves to the left in the drawing within the bearing groove 1c due to the repulsion at t 5 b.

の引出しは不可能となる。FIGS. 4 and 5 show the pulled out adhesive tape 3 adhered to the cutter 4 and locked with the locking protrusion 6 in a state where the tape 3 is under tension as shown in FIG. The drum 2 is shown in a locked state with the piece 10, and the drum 2 is stopped and the adhesive tape 3
Withdrawals will not be possible.

り離間する。When the adhesive tape 3 is peeled off from the cutter 4 to release the tension of the tape and the drum 2 is moved backward as described above, the locking protrusion 6 that was locked to the locking piece 10 is removed as shown in FIG. As shown, the control piece 11 is pushed and rotated by the hinge portion 11a in the forward rotation direction of the drum 2, and is moved back together with the drum 2 and separated from the control piece 11.

係止突起６が制御片１１より離間すると、制御片１１は
自重及びヒンジ部１１ａのヒンジ作用によって第７図に
示す元の位置に復帰回動する。When the locking projection 6 is separated from the control piece 11, the control piece 11 is rotated back to the original position shown in FIG. 7 by its own weight and the hinge action of the hinge portion 11a.

次いで、粘着テープ３を引出すためにテープに牽引伸張
力を付与すると、支持軸５は磁石５ａ、５ｂの反発力に

の状態）に移動し、ドラム２も同様に移動する。Next, when a pulling and stretching force is applied to the adhesive tape 3 in order to pull it out, the support shaft 5 resists the repulsive force of the magnets 5a and 5b and moves inside the bearing groove 1c in the direction in which the tape 3 is pulled out (the state shown in FIG. 1). ), and drum 2 moves in the same way.

この時係止突起６は第７図矢印の如く制御片１１の上面
を乗越えて移動するため、該突起６が再度係止片１０に
係止してドラム２の回転を係止する心配はない。At this time, the locking protrusion 6 moves over the top surface of the control piece 11 as shown by the arrow in FIG. .

出しを常時円滑に行なうことができる。That is, the control piece 11 is structured so that it rotates only in the forward rotation direction of the drum 2 and does not rotate in the reverse rotation direction, and since the control piece 11 is made to hang diagonally toward the reverse rotation direction of the drum 2, once Even if the locking protrusion 6 separated from the control piece 11 attempts to return to its original locking position due to an accidental reversal of the drum 2, the control piece 11 prevents this and prevents it from locking again to the locking piece 10. In order to prevent the drum 2 from rotating in the normal direction, the adhesive tape
There is no fear that the adhesive tape 3 will become impossible to draw out, and the adhesive tape 3 can be drawn out smoothly at all times.

以上の様にして粘着テープ３の引出しが進み、次位の係
止突起６が係止片１０に係止するとドラム２の回転は停
止される。As described above, the adhesive tape 3 is drawn out, and when the next locking protrusion 6 locks with the locking piece 10, the rotation of the drum 2 is stopped.

この時点で粘着テープ３は等間隔に設けた係止突起６０

ッター４によって切断する。At this point, the adhesive tape 3 is attached to the locking protrusions 60 provided at equal intervals.
The tape 3 is pulled out for a length corresponding to the interval and cut by a cutter 4.

多大である。The present invention is as described above, and since a fixed length of adhesive tape can be cut at any time according to the intervals of the locking projections protruding from the side surface of the drum at equal intervals in the circumferential direction, the adhesive tape can be cut at any time. The cutting length of the tape is always a fixed length, which eliminates tape wastage, and the pulling and cutting operations are the same as with conventional devices of this type, so anyone can easily operate it. In addition, it has an extremely simple structure, has manufacturing advantages in which mechanical members can be assembled compactly, and is economical in that it can be implemented at low cost, so its practical value is enormous.
