2. Description of the Related Art When a transfer tape is to be refilled in a coating film transfer tool, JP-A-6-286927 and Japanese Utility Model Laid-Open No.
As disclosed in Japanese Unexamined Patent Publication No. 33863 and Japanese Unexamined Utility Model Publication No. 6-35246, it is known to attach / detach a cassette including an unwinding core, a winding core, and a transfer head as one set.

[0003]

When the transfer tape is refilled, the conventional unwinding core, the winding core, and the cassette having the transfer head as a set are attached and detached together with the unwinding core and the winding core. Since the transfer head, which originally does not need to be replaced, is also replaced, there is a drawback that the refill cassette itself becomes expensive. Further, if only the unwinding core and the winding core are to be replaced, there is a drawback that it is difficult to wind and mount the transfer tape pulled out from the unwinding core on the transfer head.

In view of the above-mentioned drawbacks of the prior art, the present invention makes it easy to refill a used transfer tape and eliminates the waste of replacing the transfer head as in a conventional cassette.
It is an object of the present invention to provide a refill transfer tape that can be supplied at low cost.

[0005]

A transfer tape for refilling according to the present invention comprises a tape holder 3, and an unwinding core 1 and a winding core 2 detachably attached to the tape holder 3.
It consists of and. Unwinding core 1 that unwinds a new transfer tape
The winding core 2 for winding the used transfer tape after being unwound and subjected to the transfer operation is mounted on the tape holder 3 so that the winding point and the winding point are located on the same side edge side. At the same time, the tape holder 3 is provided with a tape guide 7 for guiding the transfer tape pulled out from the unwinding core 1 to the outside. The tape holder 3 is integrally formed of a flat plate material, in particular, a single elastic plate material in which narrow support rods 3a and 3b branch in two directions, and is used as a locking means for the unwinding core 1 and the winding core 2. The tape guide 7 can be formed by a tongue piece obtained by folding back a part of the plate material at the bases of the support rods 3a and 3b. Further, the tape guide 7 can be formed by two or more protrusions.

[0006]

When the used transfer tape is removed from the coating film transfer tool and the transfer tape is refilled with new transfer tape, the unwinding core 1 and the winding core 2 held by the tape holder 3 are transferred to the coating film transfer device. Fit it according to each mounting position of the tool. At this time, the transfer tape held by the tape holder 3 is guided outward by the tape guide 7 so as to pass outside the transfer head of the coating film transfer tool.
When the tape guide 7 is formed by two or more protrusions and the transfer tape is mounted by passing between the protrusions,
The friction between the projection and the transfer tape maintains a stable contact state between the transfer tape and the projection, thereby preventing the engagement from being disengaged and preventing the tape from moving. Also, the tape holder 3 can be easily removed when it is removed from the unwinding core 1, the winding core 2 and the transfer tape.
