Description

  The present invention belongs to the technical field of a coating film transfer tool for press-transferring a character correction coating film, an adhesive film, a decorative coating film, etc. to a transfer surface. The present invention relates to a horizontal drawing type coating film transfer tool guided in parallel to both front and back surfaces.

  There exists a thing like patent document 1 in the conventional horizontal drawing type coating-film transfer tool. FIG. 3 is a top view of a state in which the cover of the lateral drawing type coating film transfer tool a of Patent Document 1 is partially broken. The coating film transfer tool a includes a feeding reel 4 around which a transfer tape T is wound in a case 1 and a winding reel 5 that winds up the base tape T1 after coating film transfer, respectively, and a feeding core 2 and a winding core 3 respectively. Are provided so as to be rotatable and housed in the case 1, and provided with interlocking mechanisms 6 and 7 for rotating the feeding core 2 and the winding core 3 in conjunction with each other. Then, the point-shaped transfer head 8 protrudes from the end of the case 1 and one end of the transfer tape T is fed out from the feeding core 2 and twisted 90 degrees at a short distance between the guide pin GP and the transfer head 8. 8 is transferred to the take-up core 3 by being twisted again by 90 degrees at a short distance between the transfer head 8 and the guide pin GP, which is different from the guide pin GP1, via the pressure transfer unit 9. ing.

  Moreover, there exists a thing like patent document 2 in the conventional horizontal drawing type coating-film transfer tool. FIG. 4 is a perspective view showing a state in which the main body cover 22 of the lateral drawing type coating film transfer tool b of Patent Document 2 is opened. Whereas the coating film transfer tool a is a disposable type in which the transfer tape T cannot be replaced, the coating film transfer tool b can be separated into the replacement cassette 30 and the main body cassette 20, and the used replacement cassette 30 can be replaced. It is a possible exchange-type coating film transfer tool. The transfer head 8 of the coating film transfer tool b is structured to be held by the exchange cassette 30 so as to be rotatable around the transfer head axis. Then, by rotating the transfer head 8 about 90 degrees around the axis, the transfer tape T and the substrate tape T1 after coating film transfer are twisted 90 degrees on both sides of the transfer head 8. As described above, also in the coating film transfer tool b, the transfer tape T is twisted 90 degrees at a short distance around the transfer head 8.

  When using these horizontal-drawing type film transfer tools, you can transfer by moving both sides of the film transfer tool by hand and moving it horizontally without pressing your elbows. In the present age when horizontal writing has increased, there is an advantage that correction of typographical errors and the like can be made easier.

  However, in the case of the coating film transfer tool a of Patent Document 1 and the coating film transfer tool b of Patent Document 2, the transfer tape T is twisted 90 degrees at a short distance near the transfer head. The force that tries to return to the state before being applied acts. Due to this force, there is a case where the transfer tape T has a problem that the transfer tape T is biased to the left or right with respect to the traveling direction. (Hereinafter, this defect is referred to as a skew defect of the transfer tape T.) As a result, as shown in FIG. 5, the transfer tape T rides on the guide portion provided on the transfer head 8 and ends the transfer tape. There are problems that the tape is bent and that the end portion of the transfer tape is in strong contact with the inner surface of the guide portion, and the coating film on the end surface portion of the transfer tape is damaged. If the end of the transfer tape is bent, streaky scratches remain on the surface of the transferred coating film. If the coating film on the end surface of the transfer tape is damaged, the end of the transferred coating film is also damaged. .

Patent Document 3 and Patent Document 4 propose a coating film transfer tool that improves the running of the transfer tape or the base tape around the transfer head in the lateral pulling type. Patent Document 3 proposes a coating film transfer tool c in which the base tape T1 is not twisted between the transfer head 8 and the winding core 3 as shown in FIG. However, also in the coating film transfer tool c, the transfer tape T is twisted 90 degrees between the feeding core 2 and the transfer head 8 over a short distance. Therefore, the coating film transfer tool c can improve the skew problem of the base tape T1 after the coating film transfer, but it is not sufficient as a countermeasure for the skew problem of the transfer tape T before the coating film transfer.

Patent Document 4 proposes a coating film transfer tool d to which a tape guide TG is added as means for reducing the skew of the transfer tape T when the transfer tape T is twisted 90 degrees as shown in FIG. . The tape guide TG is an inclined rib, and attempts to reduce the skew of the transfer tape T by bringing the transfer tape T into contact with the inclined surface of the tape guide TG. However, since the coating film transfer tool d is also for twisting the transfer tape T by 90 degrees at a short distance, it is not sufficient as a countermeasure for skewing of the transfer tape T before the coating film transfer.

As a countermeasure against the skew problem of the transfer tape T, it is conceivable to increase the distance by which the transfer tape T is twisted 90 degrees. However, in the conventional coating film transfer tools a, b, c, and d, there is a problem that the size of the coating film transfer tool becomes very large if the distance for twisting the transfer tape T by 90 degrees is made sufficiently long. It was.

  In view of the above points, the present invention can prevent the transfer tape from being bent and the transfer tape end from being damaged due to the skew of the transfer tape in the transfer head, and the transfer tape can be smoothly twisted. -It aims at providing the small horizontal drawing type coating-film transfer tool which can be made to drive | work.

In the first invention, a feeding core and a winding core are rotatably housed in a case, a transfer head provided with a pressure transfer portion protrudes from the case end, and a transfer tape is fed out from the feeding core. Horizontal pulling type in which the base tape is wound around the winding core, and is divided into a coating film that is twisted in front and transferred to the transfer surface in the pressure transfer portion and the remaining base tape In the film transfer tool,
The horizontal draw type coating film transfer tool, wherein the transfer tape is fed out from the feeding core in a direction away from the transfer head.

  A second aspect of the invention is the horizontal drawing type film transfer tool according to the first aspect of the invention, wherein the base tape is not twisted between the transfer head and the winding core.

A third aspect of the invention is the horizontal drawing type coating film transfer tool according to the first aspect or the second aspect, wherein the feeding core is disposed between the transfer head and the winding core.

  In the coating film transfer tool of the present invention, since the transfer tape is fed out from the feeding core in the direction away from the transfer head, the transfer tape can be moved straight over a long distance after twisting the transfer tape. For this reason, it is possible to prevent the skew of the transfer tape before the coating film is transferred at the transfer head portion. Therefore, there is a problem that the transfer tape before the coating film is transferred to the guide portion provided on the transfer head and the end portion of the transfer tape is bent, or the end portion of the transfer tape is in strong contact with the inner surface of the guide portion. The problem that the coating film is damaged can be prevented. Further, in the coating film transfer tool of the present invention, the coating tape is twisted using the space at a position away from the transfer head, so that the transfer tape can be twisted in a small space. For this reason, a small-sized coating film transfer tool can be provided.

Coating film transfer tool A of the first embodiment of the present invention Coating film transfer tool B of the second embodiment of the present invention Conventional coating film transfer tool a Conventional film transfer tool b A state where the transfer tape runs on the guide section of the transfer head at the transfer head Conventional film transfer tool c Conventional coating film transfer tool d

In FIG. 1, the coating-film transfer tool A of 1st Embodiment of this invention is shown. Fig.1 (a) is a front view of the state which removed the main body cover. FIG. 1B is a cross-sectional view taken along the line m-m in FIG. FIG.1 (c) is a main body cassette of the state which removed the main body cover of the coating-film transfer tool A. FIG. FIG. 1D is an external view of the coating film transfer tool A as viewed from the replacement cover side of the replacement cassette.

When the coating film transfer tool A is used, the transfer tape T is fed from the feed reel 4 in a direction away from the transfer head 8. Thereafter, the transfer tape T is twisted 90 degrees by the three twisting means 11, 12, and 13 and reversed in the direction of the transfer head. Since the transfer tape T reversed in the direction of the transfer head advances straight without being twisted over a long distance between the twisting means 13 and the transfer head, the transfer tape that has reached the transfer head portion before the coating film transfer is hardly affected by the twist. No. For this reason, the skew of the transfer tape T does not occur in the transfer head portion due to the twisting. Moreover, as shown in FIG. 1, the three twisting means can be arranged in three dimensions along the outer diameter shape of the coating film transfer tool. For this reason, the transfer tape T can be twisted 90 degrees in a small space, and the coating film transfer tool can be made small.

  The coating film transfer tool A is composed of a main body cassette 20 and an exchange cassette 30. The main body cassette 20 includes a main body case 21, a main body cover 22, a feeding pulley 14, a take-up pulley 16, and a round belt 15. The body cover 22 is connected to the body case 21 through a hinge 23 so as to be openable and closable. A feeding pulley 14 and a take-up pulley 16 are rotatably held in the main body case 21, and a round belt 15 is wound around the pulleys 14 and 16, and both the pulleys 14 and 16 are interposed via the round belt 15. Can be linked. Further, the delivery pulley 14 is integrally provided with a spur gear that engages with a spur gear provided integrally with the delivery core 2, and the take-up pulley 16 is provided integrally with the take-up core 3. A bevel gear that engages with the bevel gear is integrally provided.

  The exchange cassette 30 includes an exchange case 31, an exchange cover 32, a transfer head 8, a feed core 2, a take-up core 3, a twisting means 12 (roller), and a transfer tape T, and a feed core 2 and a take-up core. 3 is rotatably held between the exchange case 31 and the exchange cover 32. The transfer tape T fed from the feeding core 2 contacts the twisting means 11, 12, and further twists 90 degrees by contacting the twisting means 13 after being exposed to the outside of the replacement cassette from the opening 33, and Reverse in the direction of the transfer head 8. For the twisting means 12, a roller that is rotatably held by the exchange case 31 is used, but a fixing pin that is provided integrally with the exchange case 31 may be used. Moreover, although the twisting means 11 and 13 are fixed pins provided integrally with the replacement cover 32 and the replacement case 31, respectively, rollers that are rotatably held may be used. In terms of reducing the transfer resistance of the transfer tape, it is preferable to use a rotatable roller for both the twisting means 11, 12, and 13. Further, the remaining base material tape T <b> 1 whose film is transferred by the transfer head 8 enters the exchange cassette from the opening 34 and is wound around the winding core 3.

When the replacement cassette 20 is mounted on the main body cassette 30, the spur gears provided on the feeding core 2 and the feeding pulley 14 are engaged with each other, and the bevel gears provided on the winding core 3 and the winding pulley 16 are engaged with each other. . As a result, the rotation of the feeding core 2 can be transmitted to the winding core 3 via the pulleys 14 and 16 and the round belt 15. (Hereinafter, the mechanism for transmitting the drive from the feeding core 2 to the winding core 3 is referred to as a drive transmission mechanism 40.) When the coating film transfer tool A is used and the transfer tape runs on the transfer head, the feeding core 2 is used. Then, the transfer tape T is fed out, and the feeding core 2 rotates. This rotation is transmitted to the take-up core 3 by the drive transmission mechanism 40, and the remaining base tape T <b> 1 to which the coating film is transferred by the transfer head 8 is taken up by the take-up core 3.

In the coating film transfer tool A, both cores 2 and 3 are rotated so that the winding length of the base tape T1 becomes longer than the feeding length of the transfer tape T when the coating film is transferred, and an appropriate tension is applied to the transfer tape T. By applying the tape, the transfer tape T is not loosened. At the end of use of the transfer tape, the outer diameter of the pancake of the transfer tape wound around the feeding core is reduced, so that a large tension is applied to the transfer tape. In that case, the tension applied to the transfer tape T is released by the occurrence of slip in the drive transmission mechanism 40.

  The drive transmission mechanism 40 of the coating film transfer tool of the present invention is not limited to the above-described mechanism, and after the transfer tape is unwound from the supply reel and traveled without slack, it can be wound around the take-up reel. Anything is acceptable.

In FIG. 2, the coating-film transfer tool B of 2nd Embodiment of this invention is shown. FIG. 2A is a front view showing a state in which the main body cover is removed. FIG. 2B is an nn cross-sectional view of FIG. FIG. 2C shows the main body cassette with the main body cover of the coating film transfer tool B removed. 2D is an external view of the coating film transfer tool B as viewed from the replacement cover side of the replacement cassette.

  In the coating film transfer tool A, the winding core 3 is provided between the transfer head 8 and the feeding core 2, but in the coating film transfer tool B, the feeding core is disposed between the transfer head 8 and the winding core 3. 2 is provided. In the coating film transfer tool B, since the positions of the feeding core 2 and the winding core 3 are opposite to those of the coating film transfer tool A, other components of the drive transmission mechanism 40 are also arranged in the reverse order. Further, in the coating film transfer tool B, the twisting means 11, 12, 13 can be arranged in the space around the winding core 3, so that the coating film transfer tool B is more coated than the coating film transfer tool A. The entire film transfer tool can be further reduced in size. The coating film transfer tool B is the same as the coating film transfer tool A except that the entire coating film transfer tool is downsized by changing the arrangement of the components of the drive transmission mechanism 40 and the arrangement of the twisting means 11, 12, and 13. It is the same.

  Both the coating film transfer tools A and B are configured such that the base tape T1 does not twist between the transfer head 8 and the winding core 3. However, the coating film transfer tool of the present invention may have a configuration in which the base tape T1 is twisted between the transfer head 8 and the winding core 3 as in the coating film transfer tool a. However, as an effect of reducing the skew trouble of the base tape T1, it is preferable that the base tape T1 does not twist between the transfer head 8 and the winding core 3.

  In the coating film transfer tools A and B shown in FIGS. 1 and 2, the transfer head is provided near the center of the coating film transfer tool. However, the coating film transfer tool of the present invention may be provided with a transfer head at the end of the coating film transfer tool, like the coating film transfer tool a.

  Furthermore, the coating film transfer tools A and B are exchange-type coating film transfer tools including the replacement cassette 30 and the main body cassette 20. However, the coating film transfer tool of the present invention may be a disposable coating film transfer tool such as the coating film transfer tool a.
