And a winding core of a transfer ribbon and a transfer film.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, the core of the transfer ribbon and the film of the present invention is, as shown in FIG. Parallel to the width direction of the core (10) and the left and right ends (10
h, 10 m), a cutout (70) having a substantially constant width (W) is provided as the cylindrical core (10) for the transfer ribbon and transfer film.

According to the second aspect of the present invention, as shown in FIG. 3, in a hollow cylindrical core (10) for winding and holding a transfer ribbon or a film, the width of the cylindrical core (10) is increased. Direction and at one end thereof (FIG. 4).
At the other end (right end (10h)) from the left end (10h).
m)), a cutout (70) having a substantially constant width (W) is provided so as to be divided into two from the center of the cylinder, leaving a fixed interval (D) before the cutout (70). And a cylindrical core (10) for a transfer ribbon and a transfer film, which is provided so as to be orthogonal to the cutout (70) from the end (right end (10m)) of the transfer core.

As described above, by cutting out (70) the cylindrical winding core (10) for the transfer ribbon and the transfer film, the used transfer ribbon or transfer film can be removed from the cylindrical winding core (10). When detaching, the cylindrical core (10) can be easily bent by applying pressure from the outside to the inside with a finger or the like, so that the used transfer ribbon or transfer film can be easily removed from the cylindrical core (10). 10) can be removed. In particular, the cylindrical core (10) made of plastic has excellent elasticity and can be bent more easily.

As described above, the cylindrical core (10) from which the transfer ribbon and the film have been removed can be used again as a take-up roll without being discarded as in the prior art. It contributes to resource and waste reduction and to solving environmental problems. However, the used transfer ribbon and transfer film at this time must be discarded due to problems such as confidentiality.

Here, the cutout (70) made on the core of the transfer ribbon and film of the present invention will be described in detail. For example, in the example of the core of the transfer ribbon used in the ID card making apparatus described in the section of the related art, polyethylene,
Polypropylene, polyvinyl chloride, acrylonitrile
A plastic core such as butadiene-styrene is used. As the cylindrical core (10), the width of a cutout (70) in the case of a 1.5 mm thick cylindrical outer diameter of 32 mm and a width of 78 mm is as follows. 5 to 8 is a preferable value for the deflection of the cylindrical core (10). As described above, the appropriate value of the width (W) of the cutout (70) differs depending on the material and each size of the cylindrical core (10).

As shown in FIG. 7, a conventional cylindrical winding core (10) for winding a transfer ribbon is provided at both ends of the cylindrical winding core (10) to prevent the winding shaft from idling. Since a notch (72) for hooking a hook is provided, it is impossible to deflect the cylindrical core (10), and it is impossible to remove a used transfer ribbon or the like. I had to do it.

Therefore, in the cylindrical winding core (10) of the transfer ribbon and the film of the present invention, a notch or the like for engaging a claw for preventing the winding shaft from idling is required.
As shown in FIG. 2, the cylindrical core (10) according to the first aspect of the present invention includes a stopper (80) having a claw (82) that matches the cutout (70) and a winding shaft (90). It can be set at both ends of the cylindrical core (10), thereby preventing the winding shaft (90) from idling and simultaneously bending the cylindrical core (10) due to the tension of the transfer ribbon or the transfer film. Can be prevented.

Further, the cylindrical core (10) according to the second aspect of the present invention, as shown in FIG.
A stopper (80) having two claws (82) and a take-up shaft (90) used for a conventional core that matches the condition (0) is set on both ends of the cylindrical core (10). This can prevent the winding shaft (90) from running idle and also prevent the cylindrical core (10) from bending due to the tension of the transfer ribbon or the transfer film.

[0018]

As described above, the present invention has the following effects. That is, in a hollow cylindrical core that winds and holds a transfer ribbon and a transfer film used in various transfer type printers, in parallel with the width direction of the cylindrical core, and over both ends thereof, A cutout having a fixed width is provided, or the cut is divided into two parts from the center of the cylinder, leaving a certain interval in parallel with the width direction of the cylindrical core and before one end of the core and the other end. As described above, a cutout having a substantially constant width is provided, and the cutout is a core provided so as to be orthogonal to the cutout from the other end, so that a used transfer ribbon or transfer film can be formed. When the cylindrical core is removed from the cylindrical core, pressure can be applied from the outside to the inner side of the cylindrical core with a finger or the like, whereby the core can be easily bent, and thus can be easily removed from the cylindrical core. In other words, the removed cylindrical core is not discarded as in the past,
Since it can be used again as a winding roll, it has a great economic effect, contributes to resource saving and waste reduction, and can contribute to solving environmental problems.
