[Industrial applications]

 The present invention relates to an ink ribbon guide for an ink ribbon cassette that houses an endless ink ribbon used in printers, typewriters, and the like.

[0002]

[Prior Art]

 Ink ribbon guides of conventional ink ribbon cassettes were usually fixed to the cassette, but when packaging the cassette, the storage box becomes large due to the fixed ink ribbon guides. For example, JP-A-57-156290 and JP-A-61-239978 disclose that the cassette can be made compact by making it foldable to facilitate the operation of winding the ink ribbon.

[0003]

[Problems to be solved by the device]

 Since these ink ribbon guides are rotatable in the cassette, they have an impact on packaging, and most of them are designed to slide because the ink ribbon slides inside the ink ribbon guide. At that time, it can be said that there are significant improvements in that it is easy to hang the ink ribbon and it does not stain your hands, but in recent years, a printer called a large printer, that is, a ribbon cassette and a printing unit, has been recently made. With the advent of large-scale machines where the distance between the ribbon cassette and the printing unit is extremely large, if a cassette such as the one described above is used, a guide having a length corresponding to the length between the ribbon cassette and the printing unit can be freely rotated on the cassette. However, there is a problem in that the length of the ink ribbon guide is regulated by the length between the ribbon cassette and the printing unit. To solve this problem, we proposed a cassette that allows the ink ribbon guide to be separated from the cassette so that the ink ribbon guide can be installed near the print section, which is completely separated from the cassette. However, this product has the advantage that the guide length can be set as desired and that it can be used at any distance between the cassette and the printing unit.However, when using this guide, Since the ink ribbon inserted into the ribbon guide and extended from the cassette can slide freely inside the guide during operation of the guide, it is complicated to handle. The ink ribbon, which has been pulled out for a long time and inserted in the ink ribbon guide, can be held together with the guide, and It is an object of the present invention to provide an ink ribbon guide in which the ink ribbon guide can be easily attached / detached to / from the ink ribbon incorporated in the cassette so that the ink guide and the guide can be easily handled and already circulated. And

FIG. 8 is a plan view showing another example, FIG. 8 is a vertical sectional side view taken along the line AA of FIG. 7, FIG. 9 is a plan view showing another example of the implementation of the present invention, and FIG. 10 is a side view of that of FIG. FIG. 11 is a plan view showing a state in which the ink ribbon guide according to the present invention is applied to a line printer. Reference numeral 1 is an ink ribbon cassette, 2 is an ink ribbon guide of the ink ribbon cassette 1, and 3 is an ink ribbon. .. The ink ribbon guide 2 is composed of a bottom piece 4, a front piece 5 and a side piece 6, and an ink ribbon 3 is inserted into the inside of the ink ribbon guide 2 and slides when used, but its shape is a cross section as shown in the figure. Does not have to be rectangular, and it does not matter if it has a flat tubular shape. Reference numeral 7 denotes a gripping piece, which may be integrally molded as a part of the ink ribbon guide 2 when the ink ribbon guide 2 is molded by plastic, or is different from the ink ribbon guide 2. It may be separately formed and then applied to the ink ribbon guide 2. In this case, the gripping piece 7 may be made of a thin metal piece, wire, or the like, other than plastic. In any case, it is preferable that the gripping piece 7 has a function as the front piece 5 of the ink ribbon guide 2. When the gripping piece is pressed with a finger, the gripping piece 7 is curved in the direction of the bottom piece 4 and exists in the middle together with the bottom piece 4. The ink ribbon 3 can be gripped, and when the finger is released and the pressing force of the gripping piece 7 is released, the ink ribbon 3 returns to the old shape. The gripping of the ink ribbon 3 by the gripping piece 7 is as follows. There are cases. For example, when the ink ribbon cassette having the ink ribbon guide according to the present invention is applied to the line printer 8 as shown in FIG. 11, the line printer 8 is separated from the printing portion including the ink ribbon cassette 1, the head 9 and the platen 10. Since it is long, the ink ribbon guide 2 is removed from the ink ribbon cassette 1 and brought near the printing section. For example, although not shown, it is mounted on a frame and used, but at this time, the ink ribbon 3 needs to have the required length from the ink ribbon cassette 1. The ink ribbon 3 that has been pulled out by this amount is inserted into the ink ribbon guide 2. However, when the ink ribbon guide 2 that is pulled out is manipulated by hand, the ink ribbon 3 in this state remains as it is. Since the operator slides inside the guide 2, the operator feels that the ink ribbon 3 is an obstacle. At this time, if the gripping piece 7 grips the ink ribbon 3 and operates it together with the ink ribbon guide 2, it is possible to operate conveniently, and even a printer in which the gap between the head 9 and the platen 10 is narrow. In this case, it is troublesome to insert the ink ribbon 3 into the narrow gap when the ink ribbon 3 is free to slide inside the ink ribbon guide 2 in use, but in such a case If the gripping piece 7 is used to grip the ink ribbon 3 for operation, the operation can be performed easily. Reference numeral 12 denotes a removable pin provided on the ink ribbon guide 2, and a pin insertion hole corresponding to the pin 12 is provided on the ink ribbon cassette 1 or the frame of the printer.

In addition to such gripping of the ink ribbon, the present invention allows the ink ribbon to be inserted into and removed from the inside of the ink ribbon guide. To explain, in FIG. 1, the front piece 5 of the ink ribbon guide 2 is divided into two in the longitudinal direction to form a narrow gap over the entire length, and this is used as an insertion path 11 for the ink ribbon 3. In this case, the insertion path 11 is a straight line, and the ink ribbon 3 is inserted into or pulled out of the ink ribbon guide 2 from the insertion path 11 as shown by the alternate long and short dash line. This is one in which the length of the gripping piece 7 is made substantially equal to that of the front piece 5 on both sides of the gripping piece 7 so that the insertion path 11 is in a straight line. On the other hand, the one shown in FIG. The insertion path 11 is bent by projecting from the front pieces 5 on both sides, and the ink ribbon 3 is inserted or pulled out as shown by the alternate long and short dash line. On the other hand, in the case shown in FIG. 5, the insertion path is not formed in the front piece 5 on both sides of the gripping piece 7, which only grips the ink ribbon. 1 to 6 are various examples of the ink ribbon guide 2 having the gripping piece 7, but the ones shown in FIGS. 7 and 8 are prepared by forming the ink ribbon guide 2 with a soft plastic. The ink ribbon 3 is gripped by crushing the ink ribbon guide 2 with a finger. The grips shown in FIGS. 9 and 10 are the grips shown in FIG. Similar to the case where the piece 7 does not exist, a part of the front piece 5 of the ink ribbon guide 2 is cut off to form a wall portion 13. The wall portion 13 holds the ink ribbon 3 with a finger. Is done. Of course, the insertion path may be provided even in the case described in FIGS. 7 to 10.

[Action]

 The ink ribbon guide according to the present invention allows the ink ribbon inserted into the ink ribbon guide to be freely clamped or released while being inserted, so that the ink ribbon guide can be easily and freely inserted with the ink ribbon inserted. In addition, the provision of the insertion path allows the ink ribbon to be freely inserted into and pulled out from the ink ribbon guide, making handling of the ink ribbon cassette extremely easy.

[0013]

[Effect of the device]

 The ink ribbon guide according to the present invention is capable of freely grasping and releasing the ink ribbon inserted in the ink ribbon guide, and therefore, unlike the conventional one, the ink ribbon guide is exposed. Since it is not necessary to directly pick up the ink ribbon on the part by hand, it is extremely convenient for operating the ink ribbon guide.Especially for large machines where the distance between the ink ribbon cassette and the printing section is extremely large, When detaching the ink ribbon guide from the ink ribbon cassette and bringing it to the desired position and mounting it there, you can operate it while holding the ink ribbon inserted in the ink ribbon guide with the gripping piece. The operation can be done without soiling the ink ribbon, and the ink ribbon slides freely inside the ink ribbon guide, making handling complicated. In particular, it is very convenient for loading the ink ribbon on a printer of a model with a narrow gap between the head and the platen. Since it can be pulled out, it is now possible to freely attach and detach the ink ribbon guide for the ink ribbon that is still attached to the ink ribbon cassette endlessly. Also, by making the ink ribbon guide from a material such as soft plastic, the ink ribbon guide can hold the ink ribbon simply by having a simple structure into which the ink ribbon can be inserted. However, if you do not mind the stain on your fingertips, the ink ribbon can be gripped with a simple structure without a wall, without considering the hardness of the material of the ink ribbon guide.
