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 the applicator body. The present invention relates to a transfer tape feeding / winding device.

[0002]

2. Description of the Related Art Conventionally, a transfer tape feeding / winding device in an applicator, in particular, an applicator which is adhered or modified by a transfer tape contained in the applicator body, is built in the applicator body and The supply reel color and the take-up reel color are respectively integrated with each other, and the supply head and the take-up gear, which mesh with each other, are driven to wind the supply reel color around the transfer head disposed at the tip of the applicator. It is common to send an unused transfer tape through a transfer head and at the same time wind the used transfer tape around the take-up reel collar, and remove the transfer tape wound on the collar from the applicator. By doing so, the transfer tape is replaced.

[0003]

However, in the above-mentioned conventional apparatus, the transfer tape is fed by driving the supply gear and the winding gear, which are integrated with the supply reel collar and the take-up reel collar, and mesh with each other. The supply reel collar and the take-up reel collar for winding are fixed by inserting the shafts of the respective gears rotatably attached by fixed shafts integrally formed on the inner wall of the applicator body into the inside thereof. This enables synchronized rotation of each color and each gear, and in particular, in the case of the supply reel color in which an unused transfer tape is sent to the transfer head arranged at the tip of the applicator main body, that color When the shaft of the supply gear is fitted inside the collar to prevent the idling of the supply gear and to ensure the synchronized rotation of the collar and the supply gear, Although an O-ring is interposed between the O-ring and the O-ring, the frictional force is limited because the outer wall surface of the supply gear shaft and the inner wall surface of the supply reel collar that are in contact with the O-ring have a limited frictional force. When applying or correcting with glue or a correction coating, the collar spins against the supply gear and the transfer tape overflows in the applicator body, and the transfer tape is sent out the next time it is used. However, it has the drawback that it cannot be wound up and the application or correction work with a paste or a correction coating film cannot be carried out smoothly. As a method of increasing the frictional force in order to improve this drawback, it is conceivable to increase the repulsive force of the O-ring, but a force unacceptable as a practical product is required for feeding the transfer tape. Feasibility is difficult.

Then, a rewinding button is provided so that the unused transfer tape which is redundantly fed into the applicator body by reversing the supply gear, which is usually integrated with the supply reel, can be rewound onto the supply reel collar. Although it is installed, if a large amount of unused transfer tape overflows into the applicator body, it will force the user to rewind the supply reel collar, which is extremely troublesome. If a person tries to rewind the unused transfer tape by unwinding, the transfer tape may be cut.

Therefore, the present invention solves the above-mentioned drawbacks of the prior art, and has a simple structure, even if a user vigorously applies or corrects with a paste or a correction coating film, a supply reel. This is to prevent excess unused transfer tape from being delivered from the color.

[0006]

To this end, in a transfer tape feeding / winding device built in the applicator body,
On both or one of the outer wall surface of the shaft of the supply gear and the inner wall surface of the supply reel collar, an uneven groove is provided in a direction parallel to the shaft, and the shaft of the supply gear is arranged inside the supply reel collar via an O-ring. It is fitted and fixed, or instead of the concave and convex groove provided on both or one of the outer wall surface of the shaft of the supply gear and the inner wall surface of the supply reel collar, as a rough surface,
The shaft of the supply gear is fitted and fixed inside the supply reel collar via an O-ring.

[0007]

With the above structure, a strong engaging force or frictional force (resistance) is generated between the outer wall surface of the supply gear shaft and the O-ring, and between the inner wall surface of the supply reel collar and the O-ring. Therefore, even if the applicator is moved vigorously in order to apply or correct it with glue or a correction coating film, there is a smooth surface between the color of the supply reel winding the transfer tape and the supply gear. As in the case, the frictional force does not decrease sharply after it starts to slide, there is little change from so-called static friction to dynamic friction, and a strong engaging force or frictional force is always generated, so the supply reel collar may spin idle. The transfer of excess unused transfer tape into the applicator body due to the transfer can be prevented and the transfer between the transfer head and the take-up reel collar arranged at the tip of the applicator body can be prevented. Will be given an appropriate tension to the-loop, it is possible to perform coating or modification work by smoothly glue or correction film upon next use.

In addition, when the transfer tape (4) wound around the supply reel collar (10) is fed outside the supply gear shaft (9), the supply reel collar (10) is inclined in a direction opposite to the rotating direction. Since the outer ring teeth (11) of the supply gear shaft are provided, the inner surface of the supply reel collar (10) and the O-ring (1)
3) and between the O-ring (13) and the outer surface of the supply gear shaft (9) are firmly engaged with each other, and the supply reel collar (10) rotates when the transfer tape (4) is sent out. The rotational force of the supply reel collar (10) is accurately transmitted to the supply gear shaft (9). Therefore, the rotation of the supply reel collar (10) is caused by the supply gear (7) and the winding gear (8).
It is possible to prevent the transfer tape (4) from overflowing into the applicator (1) due to the idle rotation of the supply reel color (10) by being accurately transmitted to the take-up reel color (19) via.

The firm engagement between the inner surface of the supply reel collar (10) and the O-ring (13) and between the O-ring (13) and the outer surface of the supply gear shaft (9) is Gear shaft outer ring teeth (11) and supply reel collar inner ring teeth (1
Since the respective teeth of 2) are to be engaged with the O-ring (13), the inclination direction of the respective teeth is the same as the above embodiment, regarding the supply gear shaft outer ring teeth (11). In the direction opposite to the direction in which the supply reel collar (10) rotates when the transfer tape (4) wound around the reel collar (10) is delivered, and in the supply reel color inner ring teeth (12), It is desirable that the supply reel collars (10) are respectively inclined in the rotating direction when the transfer tape (4) wound around the reel collars (10) is delivered, but this configuration is not an essential requirement.

When the outer surfaces of the supply gear shaft (9) are firmly engaged with each other and the supply reel collar (10) is rotated along with the delivery of the transfer tape (4), the rotational force of the supply reel collar (10) is increased. The same effect can be obtained by being accurately transmitted to the supply gear shaft (9). It should be noted that the terrestrial pattern provided on the inner surface of the supply reel collar (10) and the outer surface of the supply gear shaft (9) is not limited to the satin surface, but may increase the frictional force with the O-ring (13). As long as it is a rough surface such as a textured surface, a hairline surface, a parallel line surface, a fine knurled surface, and a rough knurled surface, the various rough surfaces described above can be used in combination as appropriate.

[0015]

As described above, the supply gear shaft is fitted and fixed through the O-ring to the supply reel collar for sending the unused transfer tape to the transfer head arranged at the tip of the applicator body. At this time, between the inner surface of the supply reel collar and the O-ring, or between the O-ring and the outer surface of the supply gear shaft, the teeth provided on each surface are engaged with the O-ring, or the ground pattern of each surface is provided. By the frictional force generated by the application, the supply reel collar can be prevented from idling even when the applicator main body moves suddenly, so that an extra transfer tape is sent out inside the applicator main body. It is possible to reliably and quickly apply or correct with a paste or a correction coating film, and to rewind the transfer tape by slackening the user even in the next use. Glue without forcing Are those having an excellent effect that can be used as applicator for correction film.
