Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink ribbon cassette in which an ink ribbon is incorporated so that it can be easily attached to a printer.

[0002]

2. Description of the Related Art As an ink ribbon cassette, there is an ink ribbon cassette in which the entire ink ribbon is incorporated in a resin-made box type cassette case.
Since heat of 0 Kcal / Kg and toxic gas are generated, and the entire cassette case is made of resin, a large amount of resin material is used and a large amount is used when incinerating an unnecessary ink ribbon cassette. There is a problem that the heat is generated to damage the incinerator and a problem that a large amount of toxic gas is generated. Therefore, it is possible to reduce the amount of resin by blending an inorganic filler (calcium carbonate, talc, etc.) with the case-forming resin, but a large amount of residue is generated during combustion. There is.
In order to solve these problems, the ink ribbon cassette does not have a print guide part that guides the ink ribbon to a printable running posture, but a paper-based plate is bent in a U-shape to form a cassette case. The cassette core is rotatably supported by the pay-out core and the take-up core over the plate materials facing each other, and when incinerated and discarded, there is little residue due to combustion, and a large amount of heat is generated and a large amount of heat is generated. It has been proposed to prevent the generation of toxic gas (see, for example, Japanese Patent Application Laid-Open No. 61-12384).

[0003]

According to the above-mentioned prior art, since a cassette case is constructed by bending a sheet of paper-based plate material in a U-shape, the cassette case is transported from above during storage or storage. When the load is applied, the cassette case is easily deformed and cannot be attached to the printer in a predetermined posture, or the ink ribbon cannot run in a predetermined posture, which causes printing defects. Due to the structure of the cassette case that is formed by bending the plate material into a U-shape, it is difficult to provide a print guide part that guides the ink ribbon to a printable running posture. It is necessary to pull out from the cassette case and attach it separately to the print guide provided on the printer side, which is a drawback that the attachment work is troublesome.
The present invention has been made in view of the above circumstances, and by devising the overall configuration of the ink ribbon cassette, a large amount of heat is generated and a large amount of toxic gas is generated in a state in which there are few residues accompanying incineration at the time of incineration and disposal. It is an object of the present invention to provide an ink ribbon cassette that is capable of preventing the occurrence of the occurrence of printing defects, is less likely to cause printing defects, and can be easily attached to a printer.

[0004]

In order to achieve the above-mentioned object, the ink ribbon cassette according to the present invention is characterized by a print guide portion for guiding the ink ribbon to a printable running posture, and an ink ribbon for the print guide portion. An ink ribbon is movably held in a tray-shaped resin holder that is provided with a rotating body for traveling along, and the resin holder is housed in a box together with the ink ribbon in the width direction of the ink ribbon. The positional deviation is regulated, and the box is made of a plate material made of paper or pulp, and the box can be printed with an interlocking opening that can interlock the running rotor with the printer side. And a printing opening to be exposed to the outside.

[0005]

Operation: The ink ribbon is movably held in a tray-shaped resin holder having excellent shape retention property, and the resin holder is housed in the box together with the ink ribbon. Since it is regulated by the box made of the plate material of which the material is, the structure of the resin holder can be simplified and the amount of resin required for manufacturing the ink ribbon cassette can be reduced. Further, since the resin holder is provided with the print guide portion, it is possible to save the trouble of hanging the ink ribbon along the print guide portion separately provided in the printer or the like when it is mounted on the printer side.

[0006]

Therefore, at the time of disposal by incineration, a large amount of heat and a large amount of toxic gas can be prevented with a small amount of residue due to incineration, but printing defects are less likely to occur, and moreover, Can be easily attached to the printer.
