DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer ribbon running toward a transfer position, which is wound around a core, and the end of the transfer ribbon which is fed out is adhesively fixed to the outer peripheral surface of the core via an adhesive tape. To a transfer ribbon cassette.

[0002]

2. Description of the Related Art In a transfer ribbon cassette, when a transfer ribbon is fed to an adhesive fixing position with respect to a core, a subsequent force for feeding the transfer ribbon causes the adhesive tape to resist the adhesive force. Therefore, the adhesive length in the circumferential direction with respect to the core outer peripheral surface of the adhesive tape is set in consideration of the feeding force at this time.

[0003]

For this reason, for example, the user forcibly pulls out the transfer ribbon without trying to know that the transfer ribbon has already been drawn out to the adhesive fixing position with respect to the core. The adhesive tape is peeled from the outer peripheral surface of the core against the adhesive force, or the adhesive force of the adhesive tape to the outer peripheral surface of the core is originally insufficient. When the pressure-sensitive adhesive tape is separated from the outer peripheral surface of the core by peeling from the core, the pressure-sensitive adhesive tape runs along with the transfer ribbon, and the pressure-sensitive adhesive surface adheres to the transfer head, platen, recording paper, or the like, and the subsequent transfer operation Cause trouble. The present invention has been made in view of the above circumstances, and by devising an adhesive fixing structure of the transfer ribbon to the outer peripheral surface of the core, the adhesive tape that adhesively fixes the transfer ribbon to the core has an adhesive strength. Even if a situation occurs where the adhesive tape is peeled off from the core outer peripheral surface, a transfer ribbon cassette that can effectively prevent the progress of the peeling before the entire adhesive tape is peeled off from the core outer peripheral surface. The purpose is to provide.

[0004]

In order to achieve the above object, the present invention is characterized in that in the above-mentioned transfer ribbon cassette, the transfer ribbon is provided on a side of a traveling path toward a transfer position of the transfer ribbon. An adhesive portion to which the adhesive surface of the adhesive tape peeled off from the core along with the running of the ribbon is provided, and a circumferential adhesive length of the adhesive tape to the outer peripheral surface side of the core, In that it is set to a length that can be adhered over the outer peripheral surface and the adhered portion,
The following operation and effect can be obtained from such a configuration.

[0005]

[Function] As the adhesive tape is pulled by the transfer ribbon, and the adhesive surface runs while being peeled off from the outer peripheral surface of the core against the adhesive force, the peeled adhesive surface adheres to the adhered portion. Then, the pressure-sensitive adhesive tape is in a state of adhering at a plurality of positions between the core outer peripheral surface side and the portion to be bonded.

[0006]

Therefore, even if the adhesive tape is peeled off from the outer peripheral surface of the core against the adhesive force, the resistive force against the feeding force of the transfer ribbon is reduced with the outer peripheral surface of the core. Because it can be obtained at multiple positions with the adhered part,
Before all of the adhesive tape is peeled off from the outer peripheral surface of the core, the progress of the peeling can be effectively prevented.
