Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises, in a case, a delivery core wound with a transfer tape having a coating film formed on the surface thereof and a winding core for winding the transfer tape with the coating film transferred thereon.
The present invention relates to a transfer head of a coating film transfer tool provided with a transfer head for moving a transfer tape portion between the two cores while pressing the transfer tape portion to the outside of the case and pressing the transfer tape portion against a transfer surface.

[0002]

2. Description of the Related Art For example, as disclosed in Japanese Patent Application Laid-Open No. 9-2724, a structure in which a pressing portion is rotatably or fixedly attached to the tip of a main body having a base attached to a case is disclosed. is there.

[0003]

In any of the prior arts described above, since the main body is made of a material that does not undergo elastic deformation, it is added when the pressing portion is pressed (by applying a load). The magnitude of the applied load appears on the transfer tape as it is, and the pressing piece may not move smoothly along the transfer tape or may hinder the transfer of the coating film.

[0004]

Means for Solving the Problems A feeding core wound with a transfer tape having a coating film formed on the surface thereof and a winding core for winding the transfer tape having the coating film transferred thereon are housed in a case. In a transfer head of a coating film transfer tool provided with a transfer head for projecting a transfer tape portion between cores to the outside of the case and moving the transfer tape while pressing against a surface to be transferred, an elastically deformable main body piece having a base attached to the case A pressing portion for the transfer tape is provided at the front end of the pressing portion, and a guiding portion facing the rear portion of the pressing portion via the transfer tape is continuously provided, and between the guiding portion and the main portion. The rear end side opening is provided with a slit.

1 shows an embodiment of a transfer head in a coating film transfer tool according to the present invention. FIG. 1 is a cross-sectional view of the coating film transfer tool, FIG. 4 is a schematic explanatory view at the end of coating film transfer, FIG. 4 is a front view of the transfer head, and FIG. 5 is a sectional view taken along line XX of FIG.

The coating film transfer tool B of the embodiment comprises a feeding core 1 wound with a transfer tape a having a coating film (made of a correcting agent, an adhesive or a fluorescent agent) provided on the surface thereof, and a tape on which the coating film has been transferred. The take-up core 2 for taking up a ′ is rotatably mounted on a support shaft 4 provided in a case 3, and between the cores 1 and 2, the rotational power of the feeding core 1 is applied to the take-up core 2. And a transfer head A for rotatably interposing a power transmission plate 5 for transmitting the transfer tape a to both the cores 1 and 2 and projecting the transfer tape a portion out of the case 3. When the transfer tape a is moved while being pressed against the transfer surface S by the head A, the transfer tape a is fed from the feeding core 1, and the rotating force of the feeding core 1 at the time of feeding is wound via the power transmission plate 5. Transmitted to the take-up core 2 and taken up by the take-up core 2 Tape a'winding portion than the outer diameter including the tape a core 1 are in the large diameter) is obtained by so winding the coating film transfer finished tape a'rotates.

In the transfer head A, a substantially prismatic base piece 6 is engaged with a receiving recess 7 provided by a main frame 3a and a lid frame 3b constituting the case 3, and assembled to the case 3. The leading end of the main body piece 8 connected to the central portion in the longitudinal direction of the base piece 6 is led out of the case 3, and the transfer tape a is pressed against the transfer surface S to transfer the coating film as described above. is there.

The main body piece 8 is formed of a band-like piece having a square cross section (it is not necessary to limit the cross section to a square shape), and is subjected to twisting (twist) or external force in the bending direction (the pressing piece 9 during the transfer operation).
(The pressing force applied to the transfer tape a) is made of a material (synthetic resin in this embodiment) that is elastically deformed by the load of the transfer tape a.

The pressing portion 9 has a rounded tip edge, and the rounded portion 9 ′ has the same shape on the left and right with the main portion 8 as the center, and the tape width of the transfer tape a. More width (width in the direction orthogonal to the longitudinal direction of main body piece 8)
And the rear end side (the case 3
Side) A wing piece 11 (may be omitted) adjacent to the main body piece 8 is protruded through a slit 10 of the opening, and the wing piece 1 is provided.
1, the guide pieces 12, 12 facing each other via the transfer tape a or a ′ are continuously provided so as to protrude from both front and back surfaces of the wing piece 11.

When the pressing piece 9 is pressed against the transfer surface S via the transfer tape a and the case 3 is moved, the pressing piece 9 moves while pressing the transfer tape a. The transfer tape a is fed from the feeding core 1 in accordance with the moving amount of the pressing piece 9, and the winding core 2 linked to the feeding core 1 corresponding to the fed amount winds the transferred tape a '. Then, a transfer operation of the coating film is performed. During this transfer operation, a load is applied to the pressing portion 9, so that the transferred tape a ′ is moved between the guide portions 12, 12.
The tape a or a 'is hardly detached to the side.

[0011]

According to the present invention, as described above, when a load (pressing force) more than necessary for transferring the coating film to the pressing portion is applied, the main portion elastically deforms and bends. Therefore, the transfer operation can be performed with a constant load, and a uniform coating film transfer state can be obtained.

Further, even if the contact angle of the pressing portion (transfer head) to the surface to be transferred via the transfer tape tends to change with the movement of the pressing portion during the transfer operation, the main portion is bent accordingly. Alternatively, the coating film transfer operation can be smoothly performed without causing the tape to come off from between the guide pieces by twisting and deforming to maintain a constant contact angle.
