When refilling the transfer tape, the transfer tape drawn from the unwinding core is wound around the transfer head, and the unwinding core and the take-up core are attached to the respective mounting parts. In this case, the user has to touch the transfer tape, and handling is troublesome whether the coating film of the transfer tape is a correction agent or an adhesive.
Further, in a conventional coating film transfer tool in which a cassette in which an unwinding core, a winding core, and a transfer head are set is detachable, the disposable cassette itself is expensive and uneconomical.

  In view of the above-mentioned drawbacks of the prior art, the present invention provides a coating film that can easily refill a used transfer tape and can supply a low-cost, refillable product without waste like a conventional cassette. It is an object to provide a transfer tool.

  The coating film transfer tool uses a transfer tape having a releasable coating film formed by applying a correcting agent or an adhesive on the surface, and an unwinding core 2 around which a transfer tape 7 is wound, and a winding for winding the transferred tape. The take-up core 4 is arranged in the case 1, and the unwinding core 2 and the take-up core 4 are linked by power transmission means. The transfer tape 7 unwound from the unwinding core 2 is wound around a transfer head 8 protruding out of the device, wound around the winding core 4, and moved while pressing the transfer head 8 against the surface to be transferred. The coating film applied to the transfer tape 7 is transferred.

  The case 1 includes a dish-shaped main body 1a to which the unwinding core 2, the winding core 4, and the arm 6 are mounted, and a lid 1b that covers the upper surface of the main body 1a. The unwinding core 4 is detachable from the drive shaft 3 arranged on the main body 1 a of the case 1, and the transfer head 8 is mounted on the distal end of an arm 6 whose base end is supported in the case 1. The arm 6 is rotatable between a use position where the transfer head 8 protrudes outside the device and a tape refilling position where the transfer head 8 is positioned inside the device. In the main body 1a, a wall for preventing the rotation of the arm 6 and the transfer head 8 is not formed on the rotation locus of the arm 6 and the transfer head 8, and the rotation of the arm 6 and the transfer head 8 is provided on the lid 1b covering the upper surface of the main body 1a. A wall is provided to close the trajectory portion and prevent rotation of the arm and the transfer head.

When the transfer tape is used up and a new transfer tape 7 is to be refilled, the arm 6 is rotated to move the transfer head 8 to the refill position in the apparatus, and the transfer used up to now is performed. The tension state of the tape 7 is released, and the mounted unwinding core can be easily removed.
After removing the used transfer tape, the unwinding core 4 of the new transfer tape 7 is mounted on the drive shaft 3 provided in the case 1 and the transfer tape is mounted. At this time, the transfer head 8 rotates and is at the refill position in the container. Therefore, when the transfer tape 7 is mounted, it is not necessary to wind the transfer head protruding outside the device. After the core of the new transfer tape 7 is mounted on the drive shaft 3, the arm 6 is rotated to transfer the transfer head 8. When the transfer tape 7 is moved to a use position outside the container, the transfer tape 7 is fed out, and the use state is tightened with the pins.

  According to the coating film transfer tool of the present invention, the transfer head is mounted on a rotatable arm, and the transfer head rotates between the transfer use position where the transfer head projects outside the device and the tape refilling position where the transfer head is positioned inside the device. The transfer tape can be easily wound around the outside of the transfer head when refilling the used transfer tape, and there is no need to wind the transfer tape around the transfer head outside the machine. The work can be easily performed, and when the arm is rotated to the transfer use position after the transfer tape is mounted, the transfer tape can be set in a tensioned state. The case 1 includes a dish-shaped main body 1a on which the unwinding core 2, the winding core 4 and the arm 6 are mounted, and a lid 1b which covers the upper surface of the main body 1a and can be freely opened and closed. A wall for preventing rotation is formed on the rotation locus of the transfer head 6 and the transfer head 8, and the lid 1b covering the upper surface of the main body 1a is located on the rotation locus portion of the arm 6 and the transfer head 8, and the arm and the transfer head 8 Because the wall that prevents rotation is formed, the operation of rotating the long arm is smoothly performed when the lid is opened, and the arm moves inward when the transfer is used with the lid closed. Movement can be prevented.

Hereinafter, embodiments of a coating film transfer tool according to the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a plan view of the entirety of the coating film transfer tool with a lid opened, and FIG. 2 is a vertical sectional view of the whole in a used state.

  The case 1 has a shape that is easy to hold and operate as a whole, and includes a dish-shaped main body 1a and a lid 1b that covers the upper surface of the main body. The main body 1a and the lid 1b can be freely opened and closed by a hinge 1c. In the main body 1a, a drive shaft 3 for mounting the unwinding core 2 and a drive shaft 5 for mounting the take-up core 4 are provided at regular intervals, and the base end of the arm 6 is located near the drive shaft 5. It is pivotally supported so that it can rotate in a plane. At the end of the arm 6, a transfer head 8 having a shape in which the wound transfer tape 7 can be easily pressed against the surface to be transferred is mounted. Further, the lid 1b is provided with an annular protrusion 23 for preventing the unwinding core 2 and the winding core 4 from coming off the drive shafts 3, 5.

  The drive shaft 3 of the unwinding core 2 is formed integrally with the gear 9, and the drive shaft 5 of the winding core 4 is formed integrally with the gear 10. The gear 9 and the gear 10 mesh via an idle gear 11, and are wound. The take-out core 2 and the take-up core 4 are driven to rotate in the same direction. That is, when the transfer tape 7 wound around the transfer head 8 moves while being pressed against the surface to be transferred, tension is applied to the transfer tape 7, whereby the unwinding core 2 rotates. As a new transfer tape is fed, the rotational force of the unwinding core is transmitted from the gear 9 to the gear 10 via the idle gear 11, and the transferred tape is wound up on the winding core 4. Note that the gears 9 and 10 and the idle gear 11 employ in- gear teeth.

  In the above-described transfer tape unwinding and winding mechanism, the winding core always rotates at a higher speed than the unwinding core 2 by selecting the number of teeth of the gears 9 and 10, so that the transfer tape does not loosen. It is designed to be wound up. As a result, the transfer tape 7 is always wound up while maintaining the tension state. The difference between the unwinding speed and the winding speed can be absorbed by a slip between the unwinding core and its drive shaft, that is, a slip clutch mechanism. In the slip clutch mechanism, for example, as shown in FIG. 11, a tongue 22 having elasticity is projected inward into a center hole of the unwinding core 2, and this tongue 22 is engaged with a part of the drive shaft 3. It is realized by performing power transmission jointly or closely. Alternatively, the unwinding core 2 and the winding core 4 may be driven by a slipping belt transmission mechanism.

  The base end of the arm 6 to which the transfer head 8 is mounted at the front end is supported by the support shaft 12 on the main body 1a of the case 1 near the gear 10 of the take-up core by a support shaft 12 so as to be freely rotatable. 8 freely rotates between a transfer use position protruding out of the container and a refill position located in the container. In the embodiment shown in FIG. 1, the transfer head 8 mounted on the tip is located between the unwinding core 2 and the winding core 4 at the refilling position where the arm 6 rotates inside the container. In addition, a stopper 13 is projected from the main body at the end of the rotation range of the arm 6, particularly in the rotation direction to the use position where the force when pressing for transfer acts, and the stopper 13 is It is arranged to be received in contact with the place 14. As a result, even when the transfer head is strongly pressed against the transfer surface, the good transfer can be continuously performed without the arm 6 and the transfer head 8 being displaced from the use position. Although not shown, a similar stopper may be provided at the end portion of the rotation position in the inward direction to prevent the transfer head from rotating too much inward.

  In the embodiment shown in FIG. 1, when the arm 6 is rotated, the arm 6 passes through the peripheral portion of the main body 1 a of the case 1. Therefore, the main body 1a does not have a wall for preventing the rotation of the arm 8 so that at least the arm 6 and the transfer head 8 at the tip can rotate. For example, while the peripheral wall of the main body 1a on the rotation trajectory is cut off, a wall of the rotation trajectory portion of the arm and the transfer head is formed on the lid 1b that covers the main body 1a. For example, it fits into the cut-off peripheral wall portion of the main body 1a and projects the partial wall 15 that closes this portion. In this way, it is possible to prevent the arm 6 from rotating carelessly and the transfer tape 7 from being carelessly exposed outside the container in the covered use state.

  FIG. 3 shows a procedure for refilling the transfer tape. When the transfer tape 7 has been completely used, the lid is opened, and the arm 6 is first rotated into the container as shown in FIG. 3A to remove the used transfer tape. As shown in FIG. 3 (b), a new transfer tape unwinding core and a new take-up core 4 are mounted on the drive shaft 3 of the unwinding core and the drive shaft 5 of the take-up core from which the used transfer tape has been removed. I do. At this time, the transfer tape 7 continuous between the unwinding core 2 and the winding core 4 is passed through the outside of the transfer head 8 which is rotating inward. Thereafter, as shown in FIG. 3C, when the arm 6 is rotated out of the apparatus, the transfer tape is fed out while the take-up core 4 is rotated at a speed higher than that of the unwinding core 2 and tightened. The tension is set, and the transfer tape is completely refilled.

  When the transfer tape is refilled, as shown in FIG. 8, a tape holder 16 having a fixed size and having the unwinding core 2 and the winding core 4 held at both ends is supplied as a refill product. Then, it is convenient to mount the unwinding core 2 and the winding core 4 on the drive shafts 3 and 5 while being mounted on the tape holder 16. That is, the length of the tape holder 16 shown in FIG. 8 is equal to the distance between the drive shaft 3 and the drive shaft 5. In addition, a flange-shaped tape guide is provided at the upper end of the winding core 4 so that the transferred tape can be smoothly wound.

  FIG. 9 shows a modified embodiment of the tape holder 16, wherein tongue pieces 16a and 16b for locking the unwinding core 2 and the winding core 4 are provided at the tip of the tape holder 16 branched into two branches. In addition, a tongue piece 16c for winding a continuous transfer tape 7 between the unwinding core 2 and the winding core 4 is formed at the base of the tape holder 16. The tongue piece 16c is positioned outside the transfer head 8 rotated to the refill position. Therefore, when the transfer tape mounted on the tape holder shown in FIG. 9 is used, the transfer tape inevitably collides with the transfer head 8 when the transfer tape shown in FIG. 3B is mounted. Will be.

  In the embodiment shown in FIG. 1, the arm 6 having the transfer head 8 mounted on the tip thereof rotates between the refilling position located inside the case 1 and the transfer use position protruding outside the case 1, and transfers the transfer. Since the transfer pressure is received by the stopper 13 at the use position, there is no problem in use. However, delusional inward is not always desirable. Therefore, in the embodiment shown in FIG. 4, the hemispherical projections 17 protrude from the bottom surface of the main body 1a at two positions, ie, the transfer use position where the arm 6 is rotated outward and the refill position where the arm 6 is rotated inward. At the same time, a recess 18 in which the projection 17 is fitted is provided on the back surface of the arm 6 to form a click structure that can be lightly locked. Thereby, although there is no obstacle to the operation of forcibly rotating the arm, the arm can be lightly locked at a predetermined position to prevent delusion.

  FIG. 5 is a perspective view showing a modified embodiment of the arm 6. In this embodiment, the base end of the arm has a gourd shape or a long hole shape and has two locking positions, and is locked by a strong force while being supported by the support shaft 12. A shaft hole 19 capable of moving the position is provided, and a branch rod 20 is protruded to the side of the arm. Further, a rod-shaped support rod 21 is provided upright at the end of the arm 6, and the transfer head 8 is free at least within a certain angle range so that at least the transfer tape is pressed against the support rod 21 smoothly. It is mounted to rotate.

  The shape and structure of the transfer head 8 are not particularly limited. The transfer head 8 is supported by the support rod 21 at the tip of the arm 6 as shown in FIG. 5 and also serves as the arm as shown in FIG. An edge-shaped pressing portion 8b is attached to the tip of the side plates 8a, 8a opposed vertically, and a roller-shaped transfer head 8 is supported at the tip of the arm 6 as shown in FIG. .

  In the embodiment shown in FIG. 5 in which the shaft hole for supporting the arm 6 can be locked at two arbitrary positions, the use of the transfer in which the arm protrudes out of the container as shown by a two-dot chain line in FIG. In the rotation position of the state, the transfer head 8 can be positioned in the container by pushing the arm 6, and the coating film is inadvertently transferred to a place other than the desired transfer surface during storage or carrying. Can be prevented. As described above, in order to make the transfer head 8 advance and retreat in the axial direction so as to be able to come and go in the case 1, the arm 6 itself is formed by two rods in addition to the shaft hole 19 as shown in FIG. A method of making it telescopic so as to be telescopic or a method of making the transfer head 8 movable with respect to the arm 6 are conceivable. In order to make the transfer head 8 movable with respect to the arm 6, a method is provided in which a long hole having two locking positions is provided at the tip of the arm 6, and the support rod 21 of the transfer head 8 is supported in this long hole. A method is considered in which a guide groove is engraved in the arm, and the transfer head 8 slides along the guide groove and can be locked at an arbitrary position by a locking claw. Can be

  Further, in the embodiment shown in FIG. 5, the branch rod 20 is projected from the side of the arm 6. The branch rod 20 can function as a guide for preventing the transfer tape 7 from being loosened in the case in the use state of the coating film transfer, and also, as shown in FIG. At the refilling position where it is rotated, the tip of the branch rod 20 is engaged with the gear 10 that drives the take-up core 4, and can function as a lock device for the drive mechanism of the take-up core and the take-up core. That is, when the drive mechanism is locked at the refill position of the transfer tape 7, the unwinding core and the winding core can be smoothly replaced.

  FIG. 7 is a perspective view showing still another embodiment of the arm 6. In this embodiment, the branch rod 20 is widened, and the branch rod 20 meshes with the two gears of the gear 10 and the idle gear 11 at the transfer tape refilling position where the arm 6 is rotated inward. The locking effect of the mechanism is further ensured, and one side edge of the arm 6 is formed to protrude outward. In this embodiment, the arm has a planar shape in which one side edge bulges outward. In this embodiment, when the arm 6 is rotated to the use position as indicated by a two-dot chain line, the bulge portion is formed. 61 abuts on the side wall of the main body 1a of the case 1 to prevent the arm 6 from rotating in a deceptive manner, and the stopper 13 of the embodiment shown in FIG. 1 can be omitted. Further, even when the transfer is performed while applying a strong force to the transfer head, good transfer can be continuously performed without shifting the transfer head 8 and the arm 6 from the use position.

FIG. 10 shows an embodiment in which the idle gear 11 is moved and arranged laterally (upward in the drawing) from a line connecting the center of the unwinding core 2 and the center of the winding core 4. In this embodiment, since a large space is created on the side opposite to the idle gear 11 (downward in the drawing), the rotated transfer head 8 can enter the space. As described above, when the transfer head 8 can be rotated inward as much as possible, the transfer head 8 does not hinder the transfer tape 8 much when the transfer tape is replaced. Therefore, even a transfer tape mounted on a tape holder as shown in FIG. 8 can be easily mounted. In other words, in a state where the arm is at the refill position, the transfer head 8 can be arranged inward from the transfer tape 7 spanned between the two cores 2 and 4 to be refilled. In this case, even when the refilling is performed using a tape holder having no tongue piece 16c serving as a tape guide as in the tape holder 16 shown in FIG. 8, there is no possibility that the transfer tape is caught on the transfer head 8, Refilling can be performed easily.
In the embodiment shown in FIG. 10, a part of the transfer head 8 rotated to the inner tape refilling position engages with the idle gear 11, and the drive shafts of the unwinding core and the winding core rotate. Not fixed.
