Description

The present invention relates to a coating film transfer tool used for transferring a coating film of a transfer tape in which various coating films are provided on a base tape to a transfer medium such as paper.

Conventionally, a coating film transfer tool for a correction tape that transfers a correction coating film for correcting an error from a transfer tape, or a coating film transfer tool for a tape that transfers an adhesive adhesive coating film has been used. . In such a coating film transfer tool, it is preferable that the transfer position where the coating film is to be transferred is visible when the coating film is transferred. For example, in a correction tape coating film transfer tool, it is used to correct errors, so it is preferable that a character or a figure to be corrected is visible to the user of the coating film transfer tool. Since the user can see the character or figure to be corrected, the user can accurately transfer the correction coating film onto the character or figure to be corrected. As a coating film transfer tool where the user can see where the coating film is to be transferred, a transfer head that transfers the coating film is conventionally composed of a transfer roller, and the coating film transfer tool is pushed forward in the direction of the transfer head. A coating film transfer tool for transferring a coating film to a transfer target is used. (Hereafter, the type of film transfer tool that extrudes the film transfer tool in the forward direction of the transfer head and transfers the film is referred to as a push-type film transfer tool.) This makes it possible to transfer the coating film to the transfer position without excess or deficiency compared to the case of transferring the coating film by pulling the coating film transfer tool forward. It became.

However, since such a film transfer tool uses a transfer roller for the transfer head, it is difficult to check the start position and end position of the film transfer due to the shadow of the transfer roller. In terms of ease, it was insufficient. On the other hand, a spatula-shaped transfer head and a transfer roller that rotates in contact with the transfer target during transfer of the coating film to transfer the transfer tape in the direction of the take-up portion, and projecting outside the coating film transfer tool Patent Document 1 proposes a coating film transfer tool having a convex portion that comes into contact with the body. When the coating film transfer tool of Patent Document 1 is used as a push-type coating film transfer tool, it becomes easier to confirm the start position and the end position of the coating film transfer. When a transfer tape having a relatively low adhesive strength is used, the coating film peels off from the base tape on the transfer head before being transferred to the transfer object as shown in FIG. 6, and cannot be transferred to the transfer object. There was a problem.

The present invention has been made in view of the above-described problems, and the problem to be solved by the present invention is that a push-type coating film transfer tool using a spatula-shaped transfer head is coated with a transfer head. An object of the present invention is to provide a coating film transfer tool in which a coating film does not peel from a transfer tape before the film is transferred.

The first invention is a transfer unit for feeding out a transfer tape provided with a coating film on a base tape, and a transfer for pressing the transfer tape against a transfer target and transferring the coating film from the transfer tape to the transfer target A pressing part and a winding part that winds up the base tape after transfer are housed in a housing, and the transfer pressing part pushes the coating film transfer tool forward of the transfer pressing part to cover the coated film. In the coating film transfer tool, which is a spatula-shaped transfer head to be transferred to a transfer body, when the spatula-shaped transfer head is pressed against the transfer target body to transfer the coating film, the transfer head enters the transfer head. A roller that is rotatably contacted with the transfer object is provided so that an angle formed between the transfer tape and the transfer object is not less than 60 degrees, and the remaining base on which the coating film is transferred by the transfer head is provided. The material tape contacts the outer circumference of the roller It is a coating film transfer tool according to claim.

According to a second aspect of the present invention, the roller is attached to an elastic piece that is elastically deformable with respect to the spatula-shaped transfer head, and the transfer tape and the elastic piece before the coating film is transferred by the spatula-shaped transfer head And the elastic piece is elastically deformed to press the back surface of the transfer tape before transfer of the coating film on which the coating film is not provided. The coating film transfer tool according to the first invention .

According to a third aspect of the present invention, tape guides for restricting movement of the transfer tape in the lateral direction of the transfer tape are provided on both sides of the transfer tape at a portion of the elastic piece that contacts the back surface of the transfer tape. A coating film transfer tool according to the second aspect of the invention .

As a result of intensive studies by the inventors of the present invention, by using a spatula-shaped transfer head in a push-type coating film transfer tool, the cause that the coating film before being transferred by the transfer head peels off from the transfer tape is It has been found that the advancing direction of the transfer tape is suddenly changed at the tip of the transfer head. That is, when the angle formed between the transfer tape entering the front end of the transfer head and the plane of the transfer target is small, the traveling direction of the base tape is suddenly changed at the front end of the transfer head. The coating film on the base tape cannot be attached to the rapid change of the path of the base tape, and the coating film peels off from the base tape at the tip of the transfer head.

Therefore, when the transfer head is pressed against the transfer target in order to transfer the coating film, a means for preventing the angle between the transfer tape entering the transfer head and the transfer target from becoming small is provided in the coating film transfer tool. Thus, peeling of the coating film from the transfer tape before the coating film is transferred by the transfer head can be prevented. When the angle formed between the transfer tape entering the transfer head and the transfer target is 60 degrees or more, the effect of preventing the peeling of the coating film from the transfer tape is great. Further, as a means for preventing the angle from being less than 60 degrees, if a roller that rotates on the transfer target during coating film transfer is used, the movement resistance of the coating film transfer tool on the transfer target may increase. And the film transfer tool does not easily meander.

That is, in the present invention, in a push-type coating film transfer tool using a spatula-shaped transfer head, when the transfer head is pressed against the transfer target in order to transfer the coating film, Since the roller that is rotatably contacted to the transfer object is provided so that the angle formed by the transfer object does not become less than 60 degrees, before the coating film is transferred by the transfer head without causing other problems. It was possible to prevent the coating film from peeling off from the transfer tape.

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 Coating film transfer tool C of the third embodiment of the present invention Coating film transfer tool D of 4th Embodiment of this invention Conventional film transfer tool E The figure which shows the state which the coating film peeled off from the transfer tape before a coating film was transferred with a transfer head

A coating film transfer tool A according to the first embodiment of the present invention is shown in FIG. 1 (a) is a front view of the coating film transfer tool A with the cover removed, and FIG. 1 (b) is a front view of the state with the cover of the coating film transfer tool A set, FIG. ) Is a perspective view showing details of the transfer head portion of the coating film transfer tool A, and FIG. 1D is a cross-sectional view taken along line MM in FIG.

As shown in FIG. 1, the coating film transfer tool A is composed of a casing made up of a case 1 and a cover 2, a feeding core 3 around which a transfer tape T coated with a coating film is wound, a coating film such as paper. A spatula-shaped transfer head 4 for transferring to a transfer body, a winding core 5 for winding the substrate tape T1 after the coating film is transferred, an O-ring 6 for transmitting the rotation of the feeding core 3 to the winding core 5, and The roller 7 is rotatably provided at a position protruding from the coating film transfer tool, but is not limited to this. The feeding portion of the transfer tape T, the rest of the film transferred Push-type coating film that has a winding part for winding a base tape and a roller rotatably provided at a position protruding from the coating film transfer tool, and transfers the coating film from the transfer tape with a spatula-shaped transfer head If it is a transfer tool, it is not limited to this form.

When the transfer head 4 is pressed against the transfer target so that the transfer head 4 and the roller 7 of the coating film transfer tool A are in contact with the transfer target at the same time, the angle formed between the transfer tape T entering the transfer head 4 and the transfer target. The roller 7 is provided at a position where the angle X in FIG. 1D is 60 degrees or more.

When the transfer head 4 is pressed against the transfer target so that the roller 7 does not contact the transfer target, the angle X becomes larger than when the transfer head 4 and the roller 7 simultaneously contact the transfer target. Therefore, in the coating film transfer tool A, when the transfer head 4 is pressed against the transferred material in order to transfer the coated film to the transferred material, the angle X is always 60 degrees or more. Since the angle X is always 60 degrees or more, in the coating film transfer tool A, the coating film does not peel from the transfer tape before the coating film is transferred by the transfer head. Further, in the coating film transfer tool A, it is possible to make it difficult to meander the coating film transfer tool by bringing the transfer head and the roller into contact with the transfer object during transfer of the coating film.

The coating film transfer tool B of 2nd Embodiment of this invention is shown in FIG. 2A is a perspective view showing details of a transfer head portion of the coating film transfer tool B, and FIG. 2B is a view showing a cross section taken along line MM in FIG.

In the coating film transfer tool B, the remaining base tape T1 to which the coating film has been transferred by the transfer head 4 comes into contact with the outer periphery of the roller 7 and is then wound around the winding core 5. The same as the film transfer tool A.

In the coating film transfer tool B, the base tape T1 is wound around the winding core 5 after coming into contact with the outer periphery of the roller 7, so that by pressing both the transfer head 4 and the roller 7 against the transfer target, The material tape T <b> 1 is given a conveying force from both the transfer head 4 and the roller 7. For this reason, the base tape T1 is wound around the winding core 5 without strongly pressing the transfer head 4 against the transfer target. Therefore, the coating film transfer tool B can transfer the coating film with a smaller pressing force than the coating film transfer tool A.

A coating film transfer tool C according to a third embodiment of the present invention is shown in FIG. 3A is a perspective view showing details of a transfer head portion of the coating film transfer tool C, and FIG. 3B is a view showing a cross section taken along the line MM of FIG. 3A.

In the coating film transfer tool C, the roller 7 is attached to an elastic piece 71 elastically deformable with respect to the spatula-shaped transfer head 4, and the elastic piece 71 is the transfer tape before the coating film is transferred. It is the same as the coating film transfer tool B, except that the elastic piece 71 is brought into contact with T and the elastic piece 71 is elastically deformed to push the back surface of the transfer tape T before the coating film transfer is not provided.

In the coating film transfer tool provided with both the transfer head 4 and the roller 7, in order to transfer the coating film to the transfer target, only the roller 7 is erroneously pressed to try to press the transfer head 4 against the transfer target. The film transfer tool may be moved in contact with In this case, since the transfer head 4 is not in contact with the transfer target, the coating film is not transferred, resulting in a transfer failure. In the coating film transfer tool B, since the holding part of the roller 7 is not elastically deformed, there is a high possibility that the user moves the coating film transfer tool while only the roller 7 is in contact with the transfer target. On the other hand, in the coating film transfer tool C, even if the roller 7 comes into contact with the transfer object prior to the transfer head 4, the elastic piece 71 holding the roller 7 is elastically deformed. 7, it is possible to make contact with the transfer object. For this reason, the user does not cause a transfer failure of the coating film by mistake.

Further, in the coating film transfer tool B, the holding portion of the roller 7 is not elastically deformed, whereas the spatula-shaped transfer head 4 is elastically deformed along the transfer target. In a state where the spatula-shaped transfer head 4 is deformed along the transfer target, the roller 7 cannot contact the transfer target with uniform force over the entire width, and the roller 7 does not contact the transfer target. On the other hand, it may be in a state of being biased and in contact. Since the base tape T1 on the roller 7 that is biased in contact with the transfer target is pushed to one side in the width direction of the roller 7, the base tape T1 may be poor in running.

On the other hand, in the coating film transfer tool C, since the roller 7 is rotatably attached to the elastic piece 71, the elastic piece 71 as a holding portion of the roller 7 is also elastically deformed together with the transfer head 4, and the transfer head 4 and the roller 7 are also in a state along the surface of the transfer object. For this reason, in the coating film transfer tool C, compared with the coating film transfer tool B, the running failure of the base tape T1 is less likely to occur.

Further, in the coating film transfer tool C, the elastic piece 71 comes into contact with the transfer tape T before the coating film is transferred by the spatula-shaped transfer head 4, and the elastic piece 71 is elastically deformed, whereby the coating film is transferred. The back surface of the transfer tape T before transfer, on which the coating film is not provided, is pushed. For this reason, when the roller 7 is pressed against the transfer object and the elastic piece 71 is elastically deformed, the transfer tape T entering the transfer head 4 is lifted by that amount, so the transfer tape T entering the transfer head 4 and the transfer object The angle formed by is not reduced.

The coating film transfer tool D which is 4th Embodiment of this invention is shown in FIG. 4A is a perspective view showing details of the transfer head portion of the coating film transfer tool D, and FIG. 4B is a view showing a cross section taken along the line MM of FIG. 4A.

In the coating film transfer tool D, tape guides 72 for restricting the movement of the transfer tape T to the side in the traveling direction are provided on both sides of the transfer tape T at the portion of the elastic piece 71 that contacts the back surface of the transfer tape T. It is the same as the coating film transfer tool C except that it is provided.

Since the tape guide 72 is provided on both sides of the transfer tape T, the transfer tape T does not meander from side to side even when the back surface of the transfer tape T is pressed against the elastic piece 71.

EXAMPLES Next, although an Example and a comparative example are given and this invention is demonstrated concretely, this invention is not limited to these Examples. In particular, in this embodiment, a correction tape is used as the transfer tape, but the transfer tape of the present invention is not limited to the correction tape.
