DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a coating film transfer tool with which it is possible to recover the used coating film transfer tape automatically.
BACKGROUND ART
As an example of this kind of a coating film transfer tool, Japanese Patent Publication No. 11639/1991 has hitherto been widely known. The tool disclosed in the aforementioned patent publication is made up of a pay-out reel with a coating film transfer tape wound thereon and a winding reel for recovering the used tape disposed in a case and a peak-shaped head for transfering the coating film. With such a tool, however, winding of the used coating film transfer has to be done manually.
The present inventor has developed a method in which the used coating film transfer tape is wound up automatically (Japanese Utility Model application No. 68371/1991). This coating film transfer tool is, as shown in FIGS. 6-8, made up of a coating film transfer tape pay-out reel 4 and a used coating film transfer tape winding reel 5 mounted on two supporting shafts 2, 3 embedded in the case 1 to be freely rotatable, a coating film transfer head 6 is provided protrusively out of the case 1 and a cover plate 7 is fitted to close the side opening of the case 1.
The pay-out reel 4 is made up of a boss 9 of a drive gear wheel 8 and a pay-out cylinder 10 freely rotatable on the outer periphery of the boss 9 and the boss 9 and a rim 11 are connected by 4 spokes 12. The boss 9 is made up of an outer cylinder 14 outside of an inner cylinder 13 with a given gap therebetween, with a base end of the outer cylinder 14 in connection with the inner cylinder 13. The inner cylinder having a through hole and a supporting shaft 2 inserted rotatably therethrough. On the side wall of the outer cylinder 14, there are formed a pair of clutch arms 16, each having one clutch claw 15 at the forward end thereof and the clutch claw 15 is engaged disengageably through the elasticity of the clutch arms 16 with a plurality of claws 17 formed annularly in the inner periphery of the pay-out cylinder 10. Also amid the pair of spokes 12, there are formed a pair of arc-shaped ratchet arms 19 with stopper claws 18 formed at the tip thereof and the stopper claws 18 are engaged disengageably through the elasticity of the ratched arms 19 with a plurality of claws 20 formed annularly on the inside of the case 1 to thereby prevent free rotation of the pay-out reel 4 and winding reel 15.
Meanwhile, the winding reel 5 forms a tape guiding flange 22 on the base end of a winding cylinder 21 and also forming a driven gear wheel 23 to be in mesh with a drive gear wheel 8 on the back of the flange 22 and having its supporting shaft 3 set freely rotatable through the through hole in the winding cylinder 21. The number of teeth of the driven gear wheel 23 is approximately 1/2 that of the drive gear wheel 8.
The pay-out cylinder 10 has a coating film transfer tape 24 wound thereon, then one end of the coating film transfer tape 24 is paid out from the pay-out cylinder 10, it is then twisted by 90.degree. by a guide pin 25 a little before the head 6 and led outward, thereafter it is led past the peak-shaped portion 26 of the head 6 into the case 1, the aforementioned twisting is restored until it reaches the guide pin 27 or it is further twisted by 90.degree. before it is wound on the winding cylinder 21. In the amount of the coating film transfer tape 24 wound on the pay-out cylinder 10 is approximately twice as much as the diameter of the winding cylinder 21. By the way, the coating film transfer tape 24 is so wound that the coating film to be transferred is on the outside of the loop.
When the coating film transfer tool of the aforementioned construction is used as a tool for erasing characters or the like, a white corrective paint film is to be formed as the coating film transfer tape 24 over a layer of a release agent on one side of the substrate tape with a layer of the adhesive layer applied on the white corrective paint film. In order to erase characters or the like with this coating film
