Description

  The present invention relates to a coating film transfer tool. More specifically, the present invention relates to a coating film transfer tool that uses two tapes, transfers the coating film on one tape onto the other tape, and then transfers the film after forming two layers.

  Conventionally, a coating film transfer tool having a tape having a coating film for correction or a coating film such as glue has been used. This coating film transfer tool includes a supply reel on the tape supply side and a take-up reel on the tape winding side, and moves the transfer tool by pressing the transfer head against the paper surface, thereby removing the tape from the supply reel. Pull out and rotate the supply reel and take-up reel to continuously transfer the coating film.

  By the way, when a coating film is paste, for example, the coating film is colorless and transparent, and it is difficult to confirm the transferred portion. For this reason, it is conceivable to add a colorant to the coating film so that it can be seen where it was transferred, making it easier to see the coating film part. It looks transparent at the place where it looks, and the appearance is bad.

Therefore, the applicant of the present application disclosed in Japanese Patent Application Laid-Open No. 2003-292932 contains a microcapsule containing a pH indicator in the coating film, or contains a microcapsule containing an alkaline solution and a pH indicator. The microcapsules are destroyed by the pressure applied to the surface, and the contents are ejected and gradually discolored by contact with air, or after the color is touched by the pH indicator and the alkaline solution, the color disappears gradually by contact with air. A method of coloring was proposed.

However, in the above method, since the microcapsules must be extremely small, production requires extremely high technology. In addition, the microcapsules must be easily destroyed when the coating is applied. On the other hand, in the manufacturing process, the microcapsules are destroyed by the pressure when the coating agent is applied to the tape base material or when the tape is wound. There are conflicting factors that must not be avoided, and careful management is required. These lead to a significant increase in production costs.

It is easy to peel off. Accordingly, when the first tape 19 is fed in the arrow W direction, the second tape 29 is also moved in the arrow direction by the frictional force or adhesive force between the first and second coating films 19a and 29a, and at the same time, the second tape 29 is moved to the second position P1. The second coating film 29a on the tape base material 29b is peeled off and transferred to the surface of the first coating film 19a on the first tape 19 base material 19b. As a result, a coating film in which the first coating film 19a and the second coating film 29a overlap each other on the first tape 19 is formed.

When the leading end 12a of the first transfer head 12 is pressed onto the paper surface 50 at the position P2 and moved in the direction of the arrow W, the first tape 19 is pulled out from the first supply reel 11 and sent, and at the same time, the first tape base. The coating film overlapping the two layers on the material 19b is transferred onto the paper surface 50. At this time, the coating layer that overlaps the two layers is crushed by the pressure applied by the tip portion 12a of the first transfer head 12, and the contents are mixed. At the beginning of the transfer, the coating film is a coating film with a color of the colorant of the first coating film 19a, but the color disappears over time due to the reaction between the pH indicator and the pH adjusting agent. ing. Therefore, when the coating film is applied, it becomes easy to understand where the pH indicator has been transferred due to the coloring of the pH indicator, and the color disappears over time, and the presence of the coating film is not visually recognized and the appearance is improved.

In the above embodiment, the first tape coating film 19a is a glue containing a pH indicator as a colorant, and the second tape coating film 29a is a glue containing a pH adjusting material. In other embodiments, conversely, the first tape coating film 19a can be a glue containing a pH adjusting material, and the second tape 29a can be a glue containing a pH indicator using a colorant. The colorant and decoloring agent are not limited to the pH indicator and the pH adjusting agent described above. For example, an alkaline solution and a pH indicator that are mixed and developed and then decolored by contact with air are used. Is possible .

For example, the upper and lower shafts 7 a and 7 c provided on the partition plate 7 are configured as one rotatable shaft that penetrates the partition plate 7, and each of the first and second supply reels 11 and 21 is provided on this shaft. The cylindrical portions 11a and 21a can be press-fitted so that both reels rotate integrally. However, this method is not limited. As a result, the resistance when the second tape 29 is pulled out from the second supply reel 21 by contact with the first tape 19 becomes extremely small, and the second tape 29 is reliably pulled out by the same amount as the first tape 19. Become.

Further, the first take-up reel 13 and the second take-up reel 23 may be configured to rotate integrally. For example, the upper and lower shafts 7b and 7d provided on the partition plate 7 are configured as one rotatable shaft that penetrates the partition plate 7 and the first and second take-up reels 13 and 23 are connected to the shaft. The respective cylindrical portions 13a and 23a can be press-fitted so that both reels rotate integrally. However, this method is not limited. As a result, the second supply reel 21 and the second take-up reel 23 do not need to be interlocked, the second drive gear 21d and the second driven gear 23c can be omitted, and the second supply reel 21 and the second take-up reel 23 can be omitted. Can be configured in a simple manner.
