ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a film transfer device, and more particularly to a paint transfer device which transfer a paint film paint film transfer tape, thereby enabling the device to use the tape as an eraser, marker or glue.
2. Description of the Related Art
Conventionally, such a paint film transfer device has been described in Japanese Patent Application Laid-Open Nos. 5-178525. The conventional paint film transfer device has a large gear mounted on a supply reel around which paint film transfer tape is wound, and a relatively small gear is mounted on a take-up reel which takes up the used tape, with the small gear meshing with the large gear. In operation, the paint film transfer tape is supplied from the supply reel. As the supply reel rotates, the take-up reel rotates through the large and small gears, so that the used tape is automatically taken-up.
However, such a conventional paint film transfer device is costly to manufacture due to its many components including the large and small gears.
Additionally, as the outer diameter of the supply reel becomes smaller and smaller, and that of the take-up reel correspondingly becomes larger and larger through using the paint film transfer tape, synchronization between the reels is lost, and excessive force is applied to the tape because the feeding speed becomes slower and slower, while the take-up speed becomes faster and faster. Thus, another problem is that the supply or take-up reel must be arranged to slip, which makes the arrangement unduly complicated.
SUMMARY OF THE INVENTION
In view of the foregoing and other problems of the conventional devices, an object of the present invention is to provide a paint film transfer device which can be inexpensively manufactured, and which can always synchronize supply of paint film transfer tape and taking-up of used tape with a simple arrangement.
To attain the above and other objects, a film transfer device according to a first aspect of the present invention includes a case, a supply reel around which paint film transfer tape is wound, and a take-up for taking-up the used tape which is supplied from the supply reel and used, the supply and take-up reels being rotatably mounted in the case, wherein the outermost peripheries of the supply and take-up reels constantly contact each other, such that the take-up reel is rotated as the supply reel is rotated.
In a second aspect, a paint film transfer device includes a supply reel around which a paint film transfer tape is wound, and a take-up reel for taking-up used film transfer tape which is supplied from the supply reel and used, the supply and take-up reels being rotatably mounted. Respective outermost peripheries of the supply reel and the take-up reels constantly contact each other, such that the take-up reel rotates as the supply reel rotates.
With the present invention, when the paint film transfer tape is supplied from the supply reel for use, the supply reel is rotated. Hence, since the outermost peripheries of the supply and take-up reel contact each other, the take-up reel is rotated in a direction opposite that of the supply reel, and automatically takes up the used tape.
Since supplying the paint film transfer tape and taking-up the used tape is synchronized simply without using gears, complex hardware, or the like, the paint film transfer device can be manufactured inexpensively.
Preferably, the paint film transfer device is provided with an urging mechanism which constantly urges at least one of the supply and the take-up reel in a direction where the supply reel and the take-up reel approach one another. The urging mechanism prevents slippage of the supply reel, so that the take-up reel reliably (e.g, always) rotates together with the supply reel.
Further, preferably, the urging mechanism is formed integrally with a support shaft for rotatably supporting either the supply reel or the take-up reel. Thus, the number of components is reduced, thereby allowing lower-cost manufacturing.
The present disclosure relates to subject matter contained in Japanese Patent Application No. 9-186135, filed Jul. 11, 1997, which is expressly incorporated herein by reference in its entirety.
