BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink ribbon cassette for producing a label, and more particularly to an ink ribbon cassette for producing a label which is mounted on a thermal transfer printer to perform printing on a label tape by a thermal transfer method.

[0002]

2. Description of the Related Art Conventionally, desired image information is printed on a label having an adhesive, pasted on a spine of a file, used as an index of an audio (video) cassette, or a label with a name written on one's belongings. There has been proposed a label printer and an ink ribbon cassette for producing a label capable of producing a label such as a label.

FIG. 4 is a plan view of a main part of a conventionally used ink ribbon cassette for label production. The ink ribbon cassette comprises three substantially cylindrical cores 2 rotatably supported in a ribbon cassette case 1 having a substantially rectangular planar shape.
a, 2b and 2c are arranged. Of these three cores, a core 2a is wound with a transfer tape 3 as a label tape on which characters, images, and the like are thermally transferred, and one of the remaining two cores 2b is for thermal transfer. The ink ribbon 4 is wound, and the other core 2c is arranged for winding the ink ribbon 4 for thermal transfer. The transfer tape 3 is composed of three layers of a release paper, an adhesive portion, and a printing portion, and the transfer path of the ink ribbon 4 and the transfer tape 3 is rotatably supported by guide rollers 5a and 5b, respectively. 5c is provided.

A plurality of key grooves 6 are provided on the inner peripheral surface of the core 2a around which the transfer tape 3 is wound and the core 2c arranged for winding the ink ribbon 4, respectively. A core that is formed in a spline shape and is separated from the inner peripheral surface of a core 2c that is disposed for winding the ink ribbon 4 on the left side in the figure and the transfer tape 3 on the right side in the figure. The inner peripheral surface of 2a is configured such that a take-up bobbin 9 and a delivery bobbin 10 projecting from a carriage 8 of the thermal transfer printer 7 shown in FIG.

In the ribbon cassette case 1, a concave portion 1 for disposing a thermal head 11 as a print head provided on a carriage 8 of the thermal transfer printer 7 is provided.
The intermediate portion between the ink ribbon 4 and the transfer tape 3 is led out of the ribbon cassette case 1 in the concave portion 12. The transfer tape 3 is once led out of the ribbon cassette case 1 from the opening 15 of the recess 12 through the guide roller 5a from the core 2a around which the transfer tape 3 is wound, and then again from the opening 16 of the recess 12 to the ribbon cassette. Introduced in the case.

On the other hand, the ink ribbon 4 is drawn out of the ribbon cassette case 1 from the opening 15 of the recess 12 through the guide roller 5b from the core 2b around which the ink ribbon is wound, and then is returned to the opening 16 of the recess 12 again. From the ribbon cassette case, and is wound around the core 2c via the guide roller 5c.

The transfer tape 3 and the ink ribbon 4 are positioned between the opening 15 and the opening 16 of the recess 12 and between the platen 14 of the thermal transfer printer 7 and the thermal head 11.
In this position, the thermal head 11 performs thermal transfer of the ink on the ink ribbon 4 to the transfer-receiving tape 4, which is a so-called printing operation.

In the vicinity of the opening 16 of the concave portion 12 of the cassette case 1, a guide portion 13 for guiding the transfer tape 3 introduced into the cassette case 1 from the opening 16 is formed.

[0009]

However, in such a thermal transfer printer, in the case of a printer in which the pressure applied to the head is weak, if the tape to be transferred is drawn into the ribbon cassette at a steep angle near the head, the transfer of the tape to be transferred is stopped. There is a problem that the head is pushed back due to the strength of the waist, and an appropriate pressure contact pressure cannot be obtained, and the printing is blurred.

Further, in the case of a printer having a low head contact pressure, the pull-out force of the transfer tape must be widened so as to reduce the load as much as possible because the pull-out force of the transfer tape is weak. When the pressure contact of the head is released when the pressure is reduced, the transferred tape to be wound is loosened as shown by the dotted line in FIG. 6, and the transferred tape near the head enters the ribbon cassette. There was a problem that it would.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a label producing ink ribbon cassette which can produce a label even with a printer having a low pressure. .
