At this time, the press-fitting rib 32c2 formed on the outer periphery of the cylindrical shaft portion 32c is pressed by the inner peripheral surface of the large-diameter portion 37a1. The clutch force of the clutch mechanism 4, which is the rotational force when the first supply bobbin drive shaft 37 and the second supply bobbin drive shaft 32 rotate relatively, presses the inner peripheral surface of the large-diameter portion 37a1. It is determined by the force, that is, the length with which the press-fit rib 32c2 and the large-diameter portion 37a1 are pressed. And the cyclic | annular uneven | corrugated | grooved part 32d of the front-end | tip part of the cylindrical axial part 32c has spring property by the uneven | corrugated shape. Therefore, when the annular uneven portion 32d is abutted against the step portion 37a3, the convex portion of the annular uneven portion 32d is compressed or deformed in the inner diameter direction. Therefore, the amount of insertion of the cylindrical shaft portion 32c into the large diameter portion 37a1 can be adjusted. As a result, the insertion amount of the press-fit rib 32c2 (that is, the length with which the press-fit rib 32c2 and the large diameter portion 37a1 are in press contact) is adjusted, and the clutch force can be adjusted. Therefore, the clutch force of the clutch mechanism 4 can be made constant regardless of the manufacturing error of parts.

  Next, based on FIGS. 5A to 5C, the operations of the slide piece 71 and the distal end portion of the slide portion 22 when the transfer head 21 moves in and out will be described.

  As shown in FIG. 5A, the transfer head 21 moves the retracting operation unit 7 forward from the retracted state to bring the back surface of the bar presser 23a into contact with the front surface of the unit engaging portion 71d. Then, when the in / out operation portion 7 is continuously moved forward, the inclined surfaces 22b1 and 22c1 of the slide engagement portions 22b and 22c come into contact with the rear corner portions 52h1a and 52h2a of the upper unit guide 52h1 and the lower unit guide 52h2, respectively. . When the in / out operation portion 7 is further moved forward, the slide engaging portions 22b and 22c are repelled so as to approach each other as shown in FIG. 5B, and the flat surfaces 22b2 and 22c2 are moved to the upper unit guide. 52h1 and the flat portions 52h1b and 52h2b of the lower unit guide 52h2 are in sliding contact.

  When the in / out operation portion 7 is further moved forward, the slide engagement portions 22b and 22c are restored and the stepped surfaces 22b3 and 22c3 become the upper unit guide 52h1 and the lower unit guide as shown in FIG. It is located on the front end faces 52h1c and 52h2c of 52h2 and engages. During the protruding operation, the transfer tape T is pulled by the transfer roller 21a of the transfer head 21, but since the reverse rotation of the take-up bobbin drive shaft 35 is restricted by the reverse rotation prevention mechanism 6, only the supply bobbin 82 is transferred. The transfer tape T is fed out by rotating in the feeding direction of the tape T.

  Note that when the inward / outward operation portion 7 is moved forward, the stepped portion at the front end of the guide groove 52j and the cushion bar 71c come into contact with each other and the cushion bar 71c is repelled. The operation feeling can be made good.

  The coating film transfer tool 10 is used with the transfer head 21 protruding in this manner. At this time, it is possible to receive a pressing force from the transfer head 21 during use by engaging the stepped surfaces 22b3 and 22c3 with the front end surfaces 52h1c and 52h2c of the upper unit guide 52h1 and the lower unit guide 52h2. Then, the transfer tape T is transferred from the supply bobbin 82 by the transfer operation of the transfer tape T by the coating film transfer tool 10, and the coating film is transferred onto the paper surface by the transfer roller 21 a and used by the take-up bobbin 83. Used tape is taken up. At this time, the take-up amount of the take-up bobbin 83 is always greater than the feed amount of the supply bobbin 82 (the supply bobbin transmission gear 36, the transmission gear 34, the take-up bobbin transmission gear portion 35b). ) Number of teeth is set. The difference between the feed amount and the take-up amount is adjusted by the drive clutch mechanism 8. Accordingly, an appropriate tension is always applied to the transfer tape T, and the looseness of the transfer tape T is reduced.

  When the immersion operation part 7 is retracted after using the coating film transfer tool 10, the slide piece 71 is also retracted, and the pressing parts 71a and 71b press the inclined surfaces 22b1 and 22c1. The slide engaging portions 22b and 22c approach each other. Then, the engagement between the stepped surfaces 22b3 and 22c3 and the front end surfaces 52h1c and 52h2c of the upper unit guide 52h1 and the lower unit guide 52h2 is released, and after the state of FIG. 5B, as shown in FIG. The transfer head 21 is immersed.

  During the immersion operation, the transfer tape T is wound up by the retreat stroke of the transfer head 21. The winding of the transfer tape T during this immersion operation will be described with reference to FIGS. 6 (a) and 6 (b).

  FIG. 6A shows the use of the coating film transfer tool 10 (that is, the protruding state of the transfer head 21). After the use of the coating film transfer tool 10, when the in / out operation unit 7 is moved backward, the transfer head unit 20 starts to move backward via the slide piece 71. Then, the first contact portion 22 a 1 in the slide main body portion 22 a of the slide portion 22 contacts the front edge surface of the contact protrusion 31 b of the intermediate gear 31. Since the contact of the first contact portion 22a1 with the front edge surface of the contact protrusion 31b extends below the peristaltic shafts 31c and 31d, the intermediate gear 31 has the rack portion 31a provided with the supply bobbin drive shaft gear. It swings around the peristaltic shafts 31c, 31d in a direction approaching the portion 32a (clockwise direction in FIG. 6). When the intermediate gear 31 swings, the rack portion 31a meshes with the supply bobbin drive shaft gear portion 32a. When the in / out operation portion 7 further moves rearward, the rack portion 31a also moves rearward, and the supply bobbin drive shaft gear portion 32a rotates. When the supply bobbin drive shaft gear portion 32 a rotates and the second supply bobbin drive shaft 32 rotates, the first supply bobbin drive shaft 37 also rotates through the clutch mechanism 4. When the first supply bobbin drive shaft 37 is rotated, the supply bobbin 82 is rotated and interlocked with the retreat of the transfer head 21, that is, in conjunction with the retreat of the transfer head unit 20, the transfer tape T corresponding to the retreat is transferred. Wind up. At this time, the reverse rotation of the winding bobbin 83 is restricted by the reverse rotation prevention mechanism 6. At this time, since the drive clutch mechanism 8 operates, the supply bobbin transmission gear 36 does not rotate, and the first supply bobbin drive shaft 37 and the supply bobbin transmission gear 36 rotate relatively.

  Further, the operation of the intermediate gear 31 during the protruding operation of the transfer head 21 is as follows. As shown in FIG. 7A, when using the coating film transfer tool 10 in which the transfer head 21 is immersed, the retracting operation unit 7 is moved forward. Then, the transfer head unit 20 starts to move forward via the slide piece 71. Then, as shown in FIG. 7B, the second contact portion 24c (more specifically, the corner portion 24c1 of the second contact portion 24c) of the bowl-shaped portion 24 is the rear edge surface of the contact protrusion 31b. Abut. Since the contact portion of the second contact portion 24c with the rear edge surface of the contact protrusion 31b is located below the peristaltic shafts 31c and 31d, the intermediate gear 31 is connected to the supply bobbin drive shaft gear portion 32a. The rack portion 31a swings around the peristaltic shafts 31c and 31d in the direction in which the rack portion 31a is separated (counterclockwise direction in FIG. 7B). If the in / out operation part 7 is continuously moved forward in the state of FIG. 7B, the engagement between the supply bobbin drive shaft gear part 32a and the rack part 31a is released, so the transfer tape pulled by the transfer roller 21a. T is sent out from the supply bobbin 82.

  At this time, the projecting portion 31e of the intermediate gear 31 is brought into contact with the inclined portion 24b of the bowl-shaped portion 24, so that the supply bobbin drive shaft gear portion 32a of the intermediate gear 31 and the rack portion 31a are swung in a direction away from each other. Is regulated. Accordingly, the swing stroke of the intermediate gear 31 can be minimized, so that the response of the intermediate gear 31 can be improved. In addition, since the supply bobbin drive shaft gear portion 32a and the rack portion 31a are formed by ratchet gears, the engagement between the supply bobbin drive shaft gear portion 32a and the rack portion 31a when the transfer head 21 protrudes can be reliably released. it can.

  Further, since the peristaltic shafts 31c and 31d of the intermediate gear 31 are guided by the guide portions 9 (left peristaltic shaft guide hole 33a and right peristaltic shaft guide groove 52n) which are long in the front and rear direction, the support of the peristaltic shafts 31c and 31d and the intermediate gear are supported. By combining 31 guides, a compact configuration can be achieved.

  In this way, the winding of the transfer tape T when the transfer head 21 is immersed, the supply bobbin drive shaft gear portion 32a that is rotationally connected to the rack portion 31a of the intermediate gear 31 and the supply bobbin 82 that synchronizes with the backward movement of the transfer head unit 20. It was decided to do. Since the intermediate gear 31 and the slide portion 22 of the transfer head unit 20 can be formed in a plate shape, the coating film transfer tool 10 having a simple and space-saving configuration can be obtained.

  The coating film transfer tool 10 is provided with a transfer head 21 and a rotation coupling mechanism 30 on the case body 5 side. Thereby, since the components mounted in the refill 80 discarded after replacement | exchange can be decreased, the coating-film transfer tool 10 without waste can be provided.

  Further, the supply bobbin drive shaft 3 can be integrally formed with a single component. However, as shown in the present embodiment, the supply bobbin drive shaft 3 includes the clutch mechanism 4 and includes the first supply bobbin drive shaft 37 and the second supply bobbin. More preferably, the drive shaft 32 is used. The reason is as follows.

  The amount of rewinding of the transfer tape T per rotation of the supply bobbin 82 varies depending on the remaining amount of the unused transfer tape T wound around the supply bobbin 82. Specifically, when the remaining amount of the unused transfer tape T wound around the supply bobbin 82 is large (that is, when the outer diameter of the transfer tape T on the supply bobbin 82 is large), the remaining amount is small (that is, The rewinding amount is larger than when the outer diameter of the transfer tape T in the supply bobbin 82 is small. Therefore, in the present embodiment, the clutch mechanism 4 is provided between the first supply bobbin drive shaft 37 and the second supply bobbin drive shaft 32, so that the unused transfer tape T wound around the supply bobbin 82 is removed. Regardless of the remaining amount, the rewinding amount of the supply bobbin 82 is constant. Thereby, regardless of the remaining amount of the unused transfer tape T wound around the supply bobbin 82, the transfer roller of the unused transfer tape T is always cut even when the transfer head 21 is moved in and out. 21a.

  Specifically, for example, when the reverse stroke of the transfer head 21 is 10 mm, the number of teeth of the supply bobbin drive shaft gear portion 32a and the rack portion 31a is set, and the supply bobbin 82 winds the transfer tape T. It is assumed that the transfer tape T can be rewound by 10 mm in a state where it is not. That is, the number of teeth of the supply bobbin drive shaft gear portion 32a and the rack portion 31a is set so that the rewinding amount of the supply bobbin 82 when the outer diameter of the transfer tape T in the supply bobbin 82 is the smallest is 10 mm.

  By setting in this way, it is assumed that, for example, the supply bobbin 82 is rewound by, for example, 15 mm in the initial state where a large amount of unused transfer tape T is wound around. Even in this case, during the backward movement of the intermediate gear 31 (rack portion 31a), the transfer tape T is tensioned by the reverse rotation prevention mechanism 6 of the take-up bobbin drive shaft 35, and the clutch mechanism 4 operates. Thus, the second supply bobbin drive shaft 32 rotates relative to the supply bobbin 82 and the first supply bobbin drive shaft 37 as appropriate. Therefore, the unwinding amount of the supply bobbin 82 is 10 mm. In this way, the amount of unwinding of the transfer tape T can be made constant regardless of the remaining amount of the unused transfer tape T wound around the supply bobbin 82. Then, irrespective of the remaining amount of the unused transfer tape T wound around the supply bobbin 82, the cut of the coating film of the transfer tape T can always be positioned on the transfer roller 21a.

  As mentioned above, although embodiment of this invention was described, this invention can be implemented with a various form, without being limited by this embodiment. For example, the coating film transfer tool 10 in the present embodiment includes a correction tape as the transfer tape T, but is not limited thereto, and various coating film transfer tapes such as tape glue can be used. Further, the contact protrusion 31b of the intermediate gear 31 not only protrudes downward in the vertical direction, but also swings the intermediate gear 31 if it protrudes in a direction intersecting with the direction in which the rack portion 31a extends. Can do.
