Description

  The present invention relates to a coating film transfer tool provided with a transfer tape for correction or sticking.

In general, a coating film transfer tool draws a transfer tape from a supply reel wound with a transfer tape in a housing, applies a coating film of the transfer tape to a surface to be transferred with a transfer head protruding from the housing, and then transfers the transfer tape. It is wound on a take-up reel.
In order for the coating film to be satisfactorily applied to the transfer surface, the pressing portion at the front end of the transfer head needs to be uniformly pressed against the transfer surface in the left-right direction orthogonal to the transfer direction. However, during the actual transfer operation, the housing swings to the left and right and the pressing force on the transfer surface changes. Some defects may be seen at the left and right edges of the film, or a hollow may occur at the left and right center of the film. Further, even when the hollowing does not occur, the coating film is not in close contact with the surface to be transferred, so that there is a problem that the coating film after the transfer is cracked or displaced when writing.

  In order to cope with this, for example, in Patent Document 1, there is one in which the transfer head can be slightly rotated and is not dropped from the case. However, in the case of this Patent Document 1, there is a tendency that the pressing force of the left and right central portions of the pressing portion of the transfer head is weaker than that of the left and right ends, and the above-described problems such as hollowing out cannot be sufficiently solved. .

Further, in Patent Document 2, a pressing part piece for a transfer tape is provided at the tip of an elastically deformable main part piece having a base attached to a case, and a guide that opposes the rear end of the pressing part piece via the transfer tape. A transfer head in which a piece is provided continuously and a slit at the rear end side opening is provided between the guide piece and the main piece is presented.
However, in the case of Patent Document 2, in order to make the main body piece elastically deformable, it is necessary to make the main body piece thin, and the strength is inferior, and a transfer load for elastic deformation is required. There is a usability problem.

  Further, Patent Document 3 presents a transfer head provided with a slit orthogonal to the moving direction of the transfer tape. However, in the case of Patent Document 3, the detached transfer tape enters the slit, and the user cannot return the transfer tape to the original state, which may make it unusable.

  The present invention has been made in view of the above-described situation, and the pressing force in the left-right direction at the pressing portion of the transfer head becomes uniform, and the coating film can be uniformly and satisfactorily transferred to the transfer surface. A coating film transfer tool that can directly apply the load applied to the transfer to the pressing part of the transfer head, has good responsiveness to the transfer load, and does not cause the transfer tape to come off the transfer head and become unusable. The purpose is to provide.

  According to the present invention, the above problem is solved by the following means.

(1) A supply reel in which a transfer tape is wound in a casing, a transfer head having a front end protruding from the casing for transferring the transfer tape drawn from the supply reel to a transfer surface, and a transfer tape after transfer In the coating film transfer tool including at least a take-up reel to be taken and a power transmission mechanism for interlocking the supply reel and the take-up reel, the transfer head is attached to a housing member or a housing housed in the housing. A mounting portion to be attached, a main body piece extending forward from the mounting portion, a pressing piece provided continuously at the front end of the main body piece, and left and right of the main body piece, The transfer head is formed within a predetermined range around the longitudinal axis of the main body piece, and is formed with a tape guide that is spaced apart in the direction and has a front end fixed to the pressing piece. Rotating case The coating film transfer tool, characterized in that attached to the housing the housing member or casing to.

  By adopting such a configuration, the tape guides whose front end portions are fixed to the pressing portion pieces are arranged on the left and right sides of the main body piece pieces and spaced apart from the main body piece pieces in the left and right directions, and the transfer head However, since the main body piece is pivotally attached within a predetermined range around the longitudinal axis of the main body piece, the both sides make the pressing force in the horizontal direction at the pressing portion of the transfer head uniform, and the surface to be transferred The coating film can be transferred uniformly and satisfactorily. In addition, since the transfer head is pivotally mounted, the load applied by the user to the transfer head can be directly applied to the pressing part of the transfer head, and the responsiveness to the transfer load is good, even with a light transfer load. The coating film can be transferred to the surface. Furthermore, there is no possibility that the transfer tape may be detached from the transfer head and become unusable.

(2) In the above item (1), at least the main body piece and the pressing piece in the transfer head are formed as inelastic bodies.
With such a configuration, the transfer load is easily transmitted to the center in the left-right direction of the pressing portion, and the coating film can be more uniformly and satisfactorily transferred to the transfer surface.

(3) In the above item (1) or (2), the transfer head is rotatably attached to the front end within a predetermined range, and a rotation restraining portion capable of directly restraining the rotation of the supply reel is provided in the rear half. A base member, which is a housing member housed in the housing, is rotatably supported by a base member support shaft provided at a predetermined position of the housing between the transfer head and the rotation stop portion. At the same time, the elastic return mechanism interposed between the base member and the housing causes the rotation of the supply reel to be released by rotating the base member when the transfer head is pressed against the transfer surface, and the transfer head When the pressure is released, the coating member transfer tool is configured such that the elastic member returns the base member to the original position and the rotation of the supply reel is stopped by the elastic return mechanism.

  By adopting such a configuration, the load applied by the user to the transfer can be directly applied to the pressing portion at the front end of the base member rotatably supported by the support shaft provided in the housing. Since the transfer head according to the item (1) or (2) is attached, the base member is rotated immediately after the start or end of the transfer operation without causing elastic deformation of the main body piece of the transfer head. Therefore, the effect of preventing the initial movement of the transfer and the stringing phenomenon can be exhibited well.

(4) In the above item (3), the rotation stop portion of the base member is a locking claw that can be locked to a locked tooth provided on a circumferential edge of a flange formed integrally with the supply reel, When the transfer head is pressed against the transfer surface, the base member rotates to release the engagement between the engaged teeth and the engagement claws, thereby releasing the rotation restraint of the supply reel, and the transfer head. When the pressure is released, the base member is returned to its original position by the elastic return mechanism, and the locking claw is locked to the locked teeth, so that the rotation of the supply reel is stopped. Use a film transfer tool.

  By setting it as such a structure, the coating-film transfer tool with the effect of said (3) term can be provided easily.

  The present invention provides a uniform pressing force in the horizontal direction at the pressing part of the transfer head, preventing the occurrence of voids in the transfer surface, cracks in the transferred film and cracks in the coating film during writing. Thus, it is possible to provide a coating film transfer tool that can perform a good transfer that can be performed, has good responsiveness to a transfer load, and does not cause the transfer tape to be removed from the transfer head and become unusable.

Hereinafter, the present invention will be described based on embodiments.
FIG. 1 is a perspective view showing an embodiment of a coating film transfer tool 1 of the present invention, wherein (a) is an upper perspective view and (b) is a lower perspective view. 2 is an exploded top perspective view of the coating film transfer tool 1 shown in FIG. 1, and FIG. 3 is an exploded bottom perspective view of the coating film transfer tool 1 shown in FIG.

  As shown in FIGS. 2 and 3, the coating film transfer tool 1 includes a supply reel 4 in which a transfer tape 3 is wound in a casing 2 composed of a pair of left and right casing members 2 a, and the supply reel 4. At least a transfer head 5 for transferring the drawn transfer tape 3 to the transfer surface, a take-up reel 6 for taking up the transfer tape 3 after transfer, and a power transmission mechanism for interlocking the supply reel 4 and the take-up reel 6 with each other. I have. The pair of left and right housing members 2a are coupled by a coupling shaft 2b erected on the housing member 2a to form the housing 2. In the present embodiment, the housing 2 is represented as transparent. The supply reel 4 is pivotally supported together with the supply reel gear 7 on a supply reel support shaft 8 erected on the housing member 2a as follows. The supply reel gear 7 includes a cylindrical rotary shaft 7b having an engaging portion 7a at an end thereof. The rotary shaft 7b includes a compression spring 9, an annular first spacer 10, and an annular elastic body stopper 11. After the four of the annular second spacers 12 are sequentially fitted and retained by the locking portion 7a, the rotation reel 7b of the supply reel gear 7 projects from the housing 2 The outer support shaft 8 is rotatably fitted.

  A locking projection 11 a is provided on the outer peripheral surface of the annular elastic stopper 11, and a rib-like locked portion 4 a that is locked by the locking projection 11 a is attached to the inner peripheral surface of the supply reel 4.

  As described above, the tape guide 5d in the transfer head 5 is arranged on the left and right sides of the main body piece 5b and spaced apart from the main body piece 5b in the left-right direction, and the transfer head 5 is the length of the main body piece 5b. Since these are mounted so as to be rotatable within a predetermined range around the axial line in the vertical direction, the configuration of both makes the pressing force in the horizontal direction at the pressing portion of the transfer head 5 uniform, and the coating film is evenly applied to the transfer surface. It can transfer well. Further, since the transfer head 5 is pivotably attached, the load applied by the user to the transfer can be directly applied to the pressing portion 5c of the transfer head 5, and the responsiveness to the transfer load is good. The coating film can be transferred uniformly with a load.

  The base member 17 is inserted into the support shaft insertion hole 17b through the base member support shaft 18 erected on the housing member 2a, so that the base member support shaft 18 is rotated within a predetermined range. It can be rotated. The locking tooth insertion hole 17c is formed as a long hole so as not to hinder the rotation of the base member 17. As shown in FIG. 3, a locking claw 17j as a rotation stopping portion for stopping the rotation of the supply reel 4 is provided at the rear portion of the base member 17 facing the supply reel 4.

  On the other hand, the supply reel 4 is integrally attached with a flange 20 provided with a locked tooth 20a (see FIG. 2) which can be locked by the locking claw 17j on the circumferential edge. The flange 20 may be integrally formed when the supply reel 4 is formed. In this specification, the flange 20 is referred to as being integrally formed on the supply reel 4 including the case where the flange 20 is attached to the supply reel 4. Also, the integral formation also means that the supply reel 4 and the flange 20 rotate as a unit.

  As shown in FIGS. 8A and 8B, the spring member 21 urges the base member 17 to rotate in the direction in which the locking claw 17j is locked to the locked tooth 20a of the flange 20. For this purpose, it is provided between the base member 17 and the housing 2. When the coating film transfer tool 1 is not used, as shown in (a), the locking claw 17j is locked to the locked tooth 20a of the flange 20, and the supply rotates integrally with the flange 20. The reel 4 is directly prevented from rotating.

On the other hand, when the coating film transfer tool 1 is used, the base member 17 is engaged with the flange 20 by the pressing portion 5c of the transfer head 5 being pressed against the transfer surface S as shown in FIG. The supply reel 4 can rotate by rotating in the direction in which the locking teeth 20a and the locking claws 17j are unlocked, and the transfer tape 3 wound around the supply reel 4 can be pulled out. Simultaneously with the release of the pressing of the transfer head 5, the base member 17 is rotated by the elastic restoring force of the spring member 21 to return to the original position, and the rotation of the supply reel 4 is stopped.
When not in use, the elastic ratchet claw 17d of the base member 17 is engaged with the engaging teeth 19 that rotate integrally with the take-up reel 6, as shown in FIG. The reverse rotation of the take-up reel 6 is prevented to prevent the loosening.
On the other hand, at the time of use, as shown in (b), the rotation of the base member 17 releases the locking of the elastic ratchet claw 17d and the locking teeth 19, thereby reducing the rotational resistance of the take-up reel 6. In addition, it is possible to prevent the generation of sound that occurs when the elastic ratchet claw 17d is in contact. In addition, after use, the lower part of the transfer head 5 is covered with a head cover 22 in order to protect the coating film of the transfer tape 3.

  Further, the distance L1 from the front end of the transfer head 5 attached to the front end of the base member 17 to the base member support shaft 18 is shorter than the distance L2 from the base member support shaft 18 to the locking claw 17j. It is set as follows. Thereby, the movable amount of the transfer head 5 for releasing the locking claw 17j from locking with the locked tooth 20a can be reduced, and the coating film transfer tool 1 can be used with a good feeling of use. it can.
