The process of inserting the adhesive tape into the adhesive tape storage case of the present invention formed as described above and the process of automatically withdrawing and automatically cutting the adhesive tape 400 put into the case body 100 without touching them will be described as follows. same.

(Tape embedding process)

First, when the adhesive tape 400 is inserted into the case body 100, loosen the tip of the adhesive tape 400 wound with a roll, and then open the cover 110 from the case body 100, and the tip is as shown in FIG. Insert the loose adhesive tape 400, wherein the loose adhesive tape 400 passes through the guide rod 103 so that the adhesive surface contacts the surface of the tooth surface 271 and the support hole 261 of the rubber ring 270. While the tip is to be inserted so as to be exposed to the outside of the outlet 104, and then the cover 110 is fitted to the case body 100, the adhesive tape 400 is mounted on the case body 100 is completed.

(Tape withdrawal process)

If you want to use the tape to pull out the case handle 100 holding the case body 100 by hand and pull the trigger handle 210 exposed to the outside of the case body 100 through the long hole 102 as shown in Figure 3 with the index finger (the upper flange ( As the 211 is moved back along the guide groove 224 of the track piece 220, the trigger handle 210 is moved backward while compressing the first spring (212).

However, since the push latch 250 of the trigger handle 210 is hung on the ratchet gears 232 of both belt plates 230 through the lower guide groove 223 of the track piece 220, the trigger handle 210. The push clasp 250 rotates the belt plate 230 as much as the moving distance of the support plate. When the belt plate 230 is rotated as described above, the support clasp 240 lies down while compressing the third spring 241. Since the ratchet gear 232 of the plate 230 is released freely, the belt plate 230 is smoothly rotated.

When the belt plate 230 is rotated as described above, the rubber ring 270 held in the ring hanger groove 231 of the belt plate 230 is rotated together, and the adhesive tape attached to the tooth surface 271 of the surface is rotated. As you pull the 400, the adhesive tape 400 is rotated in the hook portion 101 is gradually released.

At this time, the support hole 261 installed in the front guide 260 of the belt plate 230 is attached to the tooth surface 271 of the rubber ring 270 to support the adhesive surface of the adhesive tape 400 is advanced to the rubber ring ( Since the adhesive tape 400 is separated from the tooth surface 271 of 270, the adhesive tape 400 is smoothly advanced in the future and is discharged to the outlet 104.

Thereafter, when the trigger handle 220 is released as described above, the trigger handle 220 tries to move forward along the guide groove 224 by the repulsive force of the first spring 212 that is compressed, wherein the push clasp 250 Since the tension of the first spring 212 is much stronger than that of the second spring 251, the push clasp 250 compresses the second spring 251 and the ratchet gear 232 of the belt plate 230. In this way, the trigger handle 220 is free to return to the original position quickly along the guide groove 224.

Then, when the trigger handle 220 is returned to the original position as described above, the support latch 240 is caught by the ratchet gear 232 quickly by the elastic force of the third spring 241 that has been compressed to grasp the belt plate 230. Therefore, the rubber ring 270 inserted into the belt plate 230 and the ring hanger groove 231 maintains the rotated state.

Therefore, the present invention, while the belt plate 230 and the rubber ring 270 is rotated by the number of times to pull the trigger handle 220, even if the adhesive tape 400 is not pulled out by hand by the above process by the required length of the outlet ( 104) It can be withdrawn to the outside.

Tape Cutting Process

In order to cut the adhesive tape 400 drawn out by the required length by the drawing process, when the thumb is pulled against the operation tool 330 installed on the upper surface of the case body 100, as shown in FIG. The tip of the lever 320 is naturally lowered because the rear end of the lever 320 is lifted while being rotated about the hinge pin 107. Thus, the cutter 340 coupled to the tip of the lever 320 is a stone bar 322. Lowered together by), the pressing holes 350 are lowered together by the steel wire 323.

Then, the lowering pusher 350 is immediately caught by the end of the outlet 104, presses the upper surface of the adhesive tape 400 drawn out through the outlet 104, but is no longer lowered. However, the cutter 340 may be further moved downward along the guide groove 351 of the inner surface of the pressing hole 350 by the protrusion 322 of the lever 320 inserted into the hole 341. The steel wire 323 fitted into the 350 is bent and further lowered along the lever 320 to cut the adhesive tape 400.

In addition, when the cutter 340 cuts the adhesive tape 400, as described above, the pressing holes 350 and the ends of the discharge holes 104 firmly hold the front of the tape and thus hold the adhesive tape 400 more cleanly. Can be cut.

Then, when the adhesive tape 400 is cut as described above and the thumb that is pulling the operation tool 330 is released, the lever is pressed by the elastic force of the fourth spring 321 that was compressed during the lift operation of the rear end of the lever 320. (320) As the rear end is quickly lowered to the original position, the movable key 310 is rotated in the opposite direction, so the operation tool 300 is spontaneously moved forward to the original position, and the cutter 340 and the pressing hole coupled to the front end of the lever 320. 350 also rises quickly and returns to its original position so that the adhesive tape can be cut again.

The present invention may be used to hold the tip end of the adhesive tape to be cut when using the adhesive tape 400 as described above, but the finger fingerprints on the tip adhesive surface of the tape held by the finger so that part There is a fear that the adhesive force of.

However, in the present invention, since the end of the adhesive tape 400 cut at the time of cutting the tape maintains the state attached to the end of the outlet 104 as it is, the adhesive tape 400 remains attached to the end of the outlet 104. Just press lightly on the upper surface of the adhesive tape 400 to the portion to be attached, so there is no fear that the adhesive surface of the adhesive tape 400 is dirty, the adhesion is maintained very good.

In addition, in the present invention, when the adhesive tape 400 is to be drawn out for a long time, as described above, the tip of the adhesive tape 400 does not operate the trigger handle 210 several times, and thus the curved portion 105 of the case body 100 is used. Withdraw only until it can be reached to the contact with the end of the adhesive tape 400 to be attached to the area to be attached well and press the rounded curved portion 105 of the case body 100 by pressing The tip of the adhesive tape 400 is attached.

In this state, if the case body 100 is moved as it is, even if the belt handle 230 is not rotated by the trigger handle 210, the roll-shaped adhesive tape 400 inserted into the hook portion 101 is continuously released while the case body 100 Adhesive tape 400 is immediately attached by the curved portion 105 of the tip, and after attaching as much as the desired length, and pulling the operation tool 300 with the thumb, the cutter 340 is lowered as described above to the adhesive tape 400 Because it cuts the adhesive strength of the adhesive tape 400 is good and there is simplicity in use.

As described above, in the present invention, when the adhesive tape embedded in the case body is pulled out, it is possible to quickly and easily pull out and attach the required length of the adhesive tape without having to pull it with a finger. Even when cutting the drawn adhesive tape, the cutting part is not cut like a sawtooth, but the cutting part is cut very cleanly like cutting with a knife. As a result, the appearance after attaching the tape is beautiful, improving convenience and aesthetics after use. It is effective to let.
