A delivery gear 31 is mounted on 17a so as to be rotatable in the clockwise direction. A take-up gear 32 that meshes with the delivery gear 31 and rotates counterclockwise is attached to the support pin 17b located on the other end side opposite to the opening 15. In this case, the number of teeth of the winding gear 32 is sufficiently smaller than the number of teeth of the delivery gear 31, so that the winding gear 32 can rotate more than the delivery gear 31.

  The delivery gear 31 is provided with a retainer 33 having a reverse rotation preventing function including a sleeve 33a with a split groove. The take-up gear 32 is integrally formed with a sleeve 32a with a split groove. The delivery reel 21 is detachably attached to the sleeve 33a of the delivery gear 31 with the rotational direction regulated, and the take-up reel 22 is detachably attached to the sleeve 32a of the take-up gear 32 with the rotational direction regulated. It has become so. The delivery reel 21 and the take-up reel 22 are supported by an inner cover 13 that is accommodated inside the base 11 and faces the cover 12. The inner cover 13 is provided with a latch receiving portion 13a that removably engages with a latch claw 12b projecting from the upper end of the side wall 14 of the cover 12, and the inner cover 13 is attached to the cover 12.

Further, the upper end portions of the delivery reel 21 and the take-up reel 22 supported by the inner cover 13 are provided radially at the base end portions of the hollow auxiliary support pins 17c and 17d protruding from the inside of the cover 12. The plurality of holding ribs 17e and 17f are engaged with each other so as to be rotatable and detachable. The auxiliary support pins 17c and 17d cooperate with the support pins 17a and 17b projecting from the base 11, respectively, and rotatably support the delivery reel 21 and the take-up reel 22.

  Guide pins 17g and 17h are provided on both sides of the inner cover 13 on the opening 15 side, and the first and second guide rollers 23 and 24 are rotatable on the guide pins 17g and 17h, respectively. It is supported by. In this case, the first guide roller 23 can come into contact with the inside of the transfer tape 1 that is fed from the feed reel 21 and is stretched over the pressing roller 41 of the transfer head 40. Further, the second guide roller 24 can come into contact with the inside of the tape base material 2 of the transfer tape 1 that is wound around the take-up reel 22 from the pressing roller 41. The first and second guide rollers 23 and 24 arranged in this way can prevent the transfer tape 1 from slacking during use.

  As shown in FIGS. 3, 4, and 6, the transfer head 40 has a bifurcated swing arm that rotatably supports a pressing roller 41 at a free end and can swing in the moving direction of the transfer tape 1. 42 and a spring member 43 that urges the swing arm 42 in a direction opposite to the direction in which the transfer tape 1 is fed when not in use.

  In this case, the swing arm 42 loosely penetrates the cylindrical portion 44 that is rotatably fitted to the support shaft 50 that is horizontally mounted on the case 10 and the guide shaft 51 that is horizontally mounted on the case 10 (including the inner cover 13). Arc-shaped guide hole 45 to be formed. Further, between the free ends of both the swing arms 42, a shaft pin 46 that supports the pressing roller 41 in a rotatable manner is provided.

  In this case, as shown in FIG. 3, the support shaft 50 protrudes in a direction opposing the cover 12 and the inner cover 13 constituting the case 10, and the diameter of the support shaft 50 decreases toward the tip where the tips fit together. It is formed in a drum shape composed of a first shaft portion 50a and a second shaft portion 50b. On the other hand, the through-hole 44a of the cylindrical portion 44 of the swing arm 42 is formed in a taper shape in which the central portion in the axial direction has a minimum diameter and is expanded toward the openings at both ends. The support shaft 50 and the cylindrical portion 44 are moved in the thrust direction (axis) when the small-diameter central portion 50c in the axial direction of the support shaft 50 thus formed engages with the minimum diameter portion 44b of the through hole 44a of the cylindrical portion 44. The support shaft 50 or the cylindrical portion 44 (through-hole 44a) is inclined, and the pressure roller 41 is moved to the transfer surface 4 in the radial direction (direction orthogonal to the rotation direction). To make it more intimate.

  The spring member 43 is formed of a bifurcated leaf spring that is bent into a wave shape and protrudes from the cylindrical portion 44 of the swing arm 42, and has a tip side surface at the guide shaft 51. The direction in which the transfer tape 1 is always fed through the swing arm 42 by the elastic force (elastic force) of the spring member 43 in elastic contact, that is, the direction in which the adhesive 3 of the transfer tape 1 is transferred to the transfer surface 4. It is pressing in the opposite direction (left direction in FIG. 2). In this case, the guide shaft 51 is configured by two shaft halves 51a and 51b that protrude in a direction facing each other from the cover 12 and the inner cover 13 constituting the case 10 and whose tips are in contact with each other.

  As described above, by integrally forming the swing arm 42 and the spring member 43 in the transfer head 40, the number of constituent members can be reduced and the assembly of the members can be facilitated.

  Further, a friction means 47 is provided between the transfer head 40 formed as described above and the case 10 side to apply friction when the swing arm 42 swings. In this case, the friction means 47 is made of a viscoelastic material such as a polymer or synthetic rubber such as polyvinyl alcohol (PVA) or foamed polyurethane protruding from the outer surface of the swing arm 42, and the flat end surface 47a is on the case 10 side. {Specifically, the base 11 and the cover 12} are formed by elastically deformable friction protrusions that contact the inner surfaces. The friction means, that is, the friction projection 47 may be provided on the inner surface of the case 10 (including the inner cover 13) instead of the swing arm 42. Further, when the swing arm 42 and the case 10 are similarly formed of a material that can be elastically deformed, such as polyacetal (POM) or polycarbonate (PC), the friction projection 47 is formed on the swing arm 42 or the case 10 side inner cover 13. Including}.

  As described above, by providing the friction projection 47 (friction means) that gives friction when the swing arm 42 swings between the transfer head 40 and the case 10 side, the swing arm 42 swings. The vibration by the spring member 43 can be absorbed and the movement can be delayed. Therefore, the pressing roller 41 can be made to follow the uneven surface of the surface to be transferred, the transferability to the pressing step surface can be improved, and the repulsive vibration to the user's hand can be reduced, resulting in a comfortable feeling of use. it can.

  Further, the inner cover 13 formed as described above is fed from the delivery reel 21 and the delivery reel 21 around which the transfer tape 1 carrying the adhesive 3 as a coating film is wound on one side of the tape substrate 2. The take-up reel 22 for winding the tape base material 2 of the transfer tape 1 from which the adhesive 3 has been peeled off, the transfer head 40 and the first and second guide rollers 23 and 24 are supported. In this case, the inner side of the tape base 2 of the arc-shaped portion of the transfer tape 1 while being fed out from the delivery reel 21 and taken up on the take-up reel 22 is in order of the first guide roller 23, the pressing roller 41, and the second It is in a state of being stretched around the guide roller 24. Further, as shown in FIG. 3, the delivery reel 21 and the take-up reel 22 are in a state in which the transfer tape 1 wound around the send-out reel 21 and the take-up reel 22 are prevented from being rotated by the temporary fixing member 60. Maintained.

  Next, the usage mode of the coating film transfer tool according to the present invention will be described with reference to FIGS. First, a latch provided on the cover 12 is engaged with a latch receiving portion 13 a provided on the inner cover 13 that supports the delivery reel 21, the take-up reel 22, the transfer head 40, and the first and second guide rollers 23 and 24. The inner cover 13 is set inside the cover 12 by engaging the pawl 12b. In this state, the delivery reel 21 and the take-up reel 22 are rotatably engaged with holding ribs 17e and 17f provided radially at the base end portions of the auxiliary support pins 17c and 17d provided on the cover. Next, the inner cover 13 attached to the cover 12 is accommodated inside the base 11, and the delivery reel 21 and the take-up reel 22 are connected to the support pin 17 a of the delivery gear 31 attached to the base 11 and the take-up gear 32. The support pin 17b is mounted in a state in which the rotation direction is restricted. In this state, the locking claw 12a of the cover 12 is engaged with the locking receiving portion 11a of the base 11, and the base 11 and the cover 12 are coupled.

  The user holds the case 10 by hand, presses the pressing roller 41 against the fulcrum P1 of the transfer surface 4 to bring the adhesive 3 of the transfer tape 1 into contact with the transfer surface 4, and pulls it in the direction of arrow A. Then, the swing arm 42 rotates (moves) in the clockwise direction against the elastic force of the spring member 43, while the transfer tape 1 is sent out from the delivery reel 21 and the adhesive 3 (coating film) is transferred to the transferred surface 4. Is transcribed. At the time of this transfer, the friction projection 47 (friction means) provided between the transfer head 40 and the case 10 side absorbs the vibration caused by the spring member 43 when the swing arm 42 swings and delays the movement. Therefore, as shown in FIG. 8, the pressing roller 41 can be made to follow the uneven step surface 4a of the transfer surface 4, thereby improving the transferability to the uneven step surface 4a and causing repulsive vibration to the user's hand. It can be relaxed and provide a pleasant feeling.

  After the pressure-sensitive adhesive 3 (coating film) is transferred over a predetermined range, the pressure-sensitive adhesive 3 (coating film) is cut at the end point P2 when the transfer tool is lifted up so as to be swung away. At this time, the swing arm 42 is rotated (moved) in the direction opposite to the original position, that is, the feeding direction of the transfer tape 1 by the elastic force of the spring member 43, but the friction projection 47 (friction means) is fixed to the base 11 on the fixed side. Since the friction is applied to the inner surface of the cover 12 and the inner surface of the cover 12 to apply friction to absorb the vibration of the swing arm 42 to delay the movement, the crossing (cut in the width direction) of the adhesive 3 (coating film) is improved. Can be planned. That is, with the elastic force of only the spring member 43, the pressing roller 41 follows the transfer surface 4 and the transverse section of the adhesive 3 becomes unstable. However, the delay action of the friction projection 47 (friction means) causes the adhesive 3 to Crossing can be ensured.

  As described above, when the transfer is completed, the adhesive 3 on the transfer tape 1 is surely cut across. Therefore, the tape portion 1a with the adhesive 3 is always in contact with the pressing roller 41, and the transfer surface 4 is not used for the next use. When the pressing roller 41 is pressed against the fulcrum P1, the adhesive 3 can be positioned at the position of the fulcrum P1 of the transferred surface 4.

  In the above embodiment, the friction means 47 is formed by the elastically deformable friction protrusion 47 that contacts the swing arm 42 of the transfer head 40 and the case 10 side {specifically, the base 11 and the cover 12}. As shown in FIG. 9, the friction means is formed of a viscoelastic material interposed between the facing surfaces of the swing arm 42 and the case 10 side (specifically, the base 11 and the cover 12). The packing member 48 may be used. The packing member 48 may be adhered to either the swing arm 42 or the case 10 side (specifically, the base 11 and the cover 12).

  Moreover, although the said embodiment demonstrated the case where the coating-film transfer tool concerning this invention was applied to an adhesive transfer tool, it replaced with the adhesive, and the coating-film transfer using the transfer tape which carried the coating film of the correction coating agent instead of an adhesive Of course, it can also be applied to tools.
