Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an applicator, and more particularly to an applicator which is adhered or modified by a glue or a modified coating film transfer tape (hereinafter, referred to as "transfer tape") incorporated in a main body of the applicator. Transfer tape winding and winding mechanism.

[0002]

2. Description of the Related Art Conventionally, a transfer tape feeding and winding mechanism of an applicator, particularly an applicator which is adhered or corrected by a transfer tape built in the applicator main body, is built in the applicator main body. The supply reel collar and the take-up reel collar are integrated with each other, and are driven by the supply gear and the take-up gear that mesh with each other, and are wound around the supply reel collar with respect to the transfer head disposed at the tip of the applicator. In general, an unused transfer tape is sent out and a used transfer tape is wound around a take-up reel collar via a transfer head.

[0003]

However, in the above-mentioned conventional transfer tape feeding and winding mechanism, the transfer tape is exposed outside at the tip of the transfer head.
When not in use, the transfer tape pulled from the outside for some reason causes the supply reel collar to rotate, causing the transfer tape to be slackened inside or outside the applicator container, and furthermore, each gear has a small load. When rotated by force, the transfer tape exposed from the transfer head
Each gear rotates only by rubbing against an object other than the object to be transferred, and there is a disadvantage that the corrected coating film or the like is transferred to the object and becomes soiled.

Accordingly, the present invention is to improve the above-mentioned drawbacks of the prior art, and has a simple structure for preventing the rotation of each gear when the applicator is not used.

[0005]

For this purpose, the transfer head member is made rotatable, and the transfer head member is provided with a locking projection which meshes with one of the gears. The rotation projection of the transfer head member with respect to the applicator case or a base provided in the applicator case causes the transfer protrusion to substantially move the center of the transfer head member provided with the engagement protrusion on the other end side of the transfer head. Is fixed rotatably at a position where meshing with the take-up gear and release thereof are free, and an elastic body is engaged with the transfer head member. The engagement projection and the winding gear are kept in mesh with each other.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With the above construction, the transfer head member is rotated when the applicator is not used, and the rotation of the gear is prevented by a locking projection provided at one end thereof when the applicator is not used. Thus, it is possible to prevent the transfer tape from being unnecessarily sent out from the supply reel color collar. In particular, by engaging the elastic body with the transfer head member, the rotation of the gear can be automatically prevented when the applicator is not used.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. (1) is an applicator according to an embodiment of the present invention,
Inside the applicator case (2), the supply gear (3)
Has a supply reel collar (4) and a take-up gear (5)
The take-up reel collars (6) are fitted and fixed coaxially with each other, and the supply gear (3) and the take-up gear (5) are engaged with each other and driven, and rotate clockwise (arrows) in the figure. Transfer tape (7) wound on supply reel collar (4)
Constitutes a part of the transfer head member (8), is wound around a transfer head (9) protruding from the tip of the applicator case (2), and rotates counterclockwise (arrow) in the drawing. It is taken up by a take-up reel collar (6). The transfer head member (8) is rotatably fixed by being fitted to a fixing pin (11) provided on the applicator case (2) at the center point (10). A stopper (12), which is a locking projection that bends and projects toward the take-up gear (5), is provided on the end side. The stop (12) and the take-up gear (5) are engaged or released, and the transfer head (9) at the other end is engaged.
The size of the transfer head member (8) and the positioning of the center point (10) and the fixing pin (11) as well as the rotation of the transfer head member (8) so that the protrusion protrudes from the applicator case (2). It goes without saying that the range and the size of the stopper (12) are adjusted. A return spring (13) has one end engaged with a spring stopper (14) provided on the applicator case (2) and engaged with a spring retainer (15) provided at a substantially intermediate position thereof. And the other end is at the center point (10).
It engages with the transfer head member (8) at the more distal end side.
When the stopper (12) of the transfer head member (8) is engaged with the take-up gear (5), its elasticity does not act, and the transfer head ( 9) is pressed to the left in the figure and rotates clockwise about the center point (10), so that when the engagement between the stopper (12) and the winding gear (5) is released, the transfer head member (9) is released. The elasticity acts on 8).

Since the present invention has the above configuration, the transfer head member (8) can be used when the applicator (1) is not used.
The stopper (12) meshes with the winding gear (5),
In order to prevent rotation of the take-up gear (5) and the supply gear (3) meshing with the take-up gear (5), the transfer tape (7) wound around the supply reel collar (4) is not unnecessarily sent out and the transfer is performed. It is possible to prevent the tape (7) from being loosened and the transfer tape (7) from being stained on objects other than the transfer target. In particular, in order to rotate the transfer head member (8), a pressing force opposing the elasticity of the return spring (13) is required, so that the coating tool (1) is wound with the stopper (12) when not in use. The engagement with the gear (5) becomes stable. On the other hand, when the applicator (1) is used, a leftward pressing force is applied to the transfer head (9), and the transfer head member (8) rotates leftward about the center point (10). The gears (3) and (5) are disengaged from each other by moving the stopper (12) and the winding gear (5) so that the gears (3) and (5) can rotate. 7) Sending and winding are performed. At this time, since the return spring (13) is deformed in accordance with the rotation of the transfer head member (8), the use of the applicator (1) is stopped, that is, the transfer head (9) is pushed to the left. When the pressure is released, the transfer head member (8) automatically turns rightward by the elasticity of the return spring (13),
The stopper (12) meshes with the winding gear (5). In order to make it possible to replace the transfer tape (7), when a cartridge in which the gears (3) and (5) and the transfer head member (8) are integrated is used, the transfer head member (8) is used.
Is also rotatably fixed to the base of the cartridge.

[0009]

As described above, one end of the transfer head member can be engaged with the winding gear using the stopper as a stopper.
By engaging the return spring with the transfer head, with a simple structure, when the use of the applicator is stopped, the stopper automatically stops driving each gear, preventing the transfer tape from loosening, This has an excellent effect that contamination of an object other than an object to be transferred by the transfer tape can be prevented.
