[0003]

As will be understood from the fact that this ink ribbon cassette has been proposed in the late 1975's, a printer of a normal size, in which the distance between the ink ribbon cassette and the printing section is short, is known. Used in large printers that have recently been adopted,
The ink ribbon cassette and the printing unit are significantly separated,
When trying to use this conventional one for a printer or the like that pulls out the ink ribbon for a long time, the ink ribbon guide is engaged with the cassette case and its position is fixed. It must be wound up and placed in the cassette case, and the ink ribbon pulled out at that time may be twisted or loosened,
In this invention, the ink ribbon guide is located at a free position away from the ink ribbon cassette body, regardless of the interval between the printing unit and the ink ribbon cassette. It is an object of the present invention to provide an ink ribbon cassette that can sufficiently fulfill the role of a guide.

[0004]

In order to achieve the above object, the present invention is directed to an ink ribbon cassette comprising an ink ribbon cassette body 1 and an ink ribbon guide provided with a mounting structure for a printer 11, wherein an ink ribbon 3 is provided. The ink ribbon 3 is inserted through the guide 8 and pulled out from the ink ribbon cassette main body 1 by at least a necessary length at the time of use. The length of the ink ribbon 3 is folded on the ink ribbon cassette main body 1, and the ink ribbon guide 8 is placed on the folded ink ribbon 3.
Is the ink ribbon cassette on which is placed.

[0005] In this invention, there are a removable ink ribbon guide and an ink ribbon cassette main body, and a removable ink ribbon cassette body, which is not detachable and both are separated from each other. The ink ribbon cassette body is provided with a convex portion, and the ink ribbon cassette main body is provided with a concave portion corresponding to the convex portion, and the convex portion of the ink ribbon guide is fitted into the concave portion of the ink ribbon cassette main body. To remove the ink ribbon guide,
The structure provided on the ink ribbon guide and the ink ribbon cassette main body for attaching and detaching them to and from each other is not limited to the above-mentioned convex and concave portions, but in addition, two objects can be used. Any structure can be used as long as it is commonly used to make it detachable.

In the present invention, the reason why the ink ribbon guide and the ink ribbon cassette main body cannot be detached and remain separated is because the manner in which such an ink ribbon cassette is used is mainly as follows. That is, in a printer in which such an ink ribbon cassette is preferably used, the ink ribbon cassette and the printing section are remarkably separated from each other, and the ink ribbon guide is often drawn out and used. Therefore, the ink ribbon guide is separated from the ink ribbon cassette. In many cases, it is convenient to attach the printer to a printer near the printing unit and use it. Both the set body and the ink ribbon guide need to be passed to the user at the same time, and after the user receives the ink ribbon cassette, the user can immediately use the ink ribbon guide by mounting the ink ribbon guide to a necessary part of the printer. In this case, the ink ribbon guide has an ink ribbon It is most preferred that is inserted through, and only the length ink ribbon required is drawn. If the use is started in this way, the ink ribbon guide is hardly mounted on the ink ribbon cassette body.

In the present invention, since the ink ribbon cassette and the printing section are used in a printer in which the printing section is significantly separated, when the ink ribbon of a required length is drawn out of the ink ribbon cassette in advance and provided to the user, the following is required. It is good to provide in this way. That is, the ink ribbon is inserted in advance through the ink ribbon guide, and the ink ribbon pulled out at least for a necessary length at the time of use is provided with a storage portion for the ink ribbon guide at a part of the surface of the ink ribbon cassette main body. Of the drawn-out ink ribbons, the excess length of the ink ribbon when the ink ribbon guide is stored in the storage section is first folded and stored in the storage section, and the ink ribbon guide is stored on the ink ribbon. At this time, when the ink ribbon and the ink ribbon guide are stored, it is sufficient if the ink ribbon cassette body can be stored so as not to cause unevenness on the surface thereof, but it is not necessary to be concerned with the unevenness on the surface of the ink ribbon cassette body. In some cases, it was folded directly on the surface of the ink ribbon cassette body without providing a storage Nkuribon and the ink ribbon guide and may be put.

In the present invention, when the ink ribbon guide is separated from the ink ribbon cassette main body and installed near the printer printing section, the ink ribbon guide may have a structure suitable for mounting the ink ribbon guide at an appropriate position on the printer.
For example, one means is to provide a projection in the ink ribbon guide while providing a hole for receiving the projection in an appropriate position of the printer, and to attach the ink ribbon guide to the printer by using these holes.
