[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an ink ribbon recycling apparatus suitable for applying a new ink to an ink ribbon used in a dot printer, particularly an endless type used ink ribbon, and recycling an ink ribbon that has been discarded as used. Is.

[0002]

[Prior Art]

 In the past, ink ribbons used in dot printers that had a low print density were usually discarded. However, the applicant of the present application proposed an ink ribbon reclaiming device in Japanese Patent Application No. 2-115030, as it is unavoidable to sufficiently use the ribbon and the cassette case except for the ink portion. In the above-mentioned Japanese Utility Model Application No. 2-115030, the motor connected to the main shaft for transmitting the power for winding and winding the ink ribbon of the ink ribbon cassette is arranged inside the housing. .. At the upper end of the main shaft, shaft end plates corresponding to a plurality of types of shafts for feeding and winding the ink ribbon are rotatably supported by pins.

An ink pad for replenishing the ink ribbon to be replenished with ink is rotatably supported at the end of the housing opposite to the cassette holder so as to rotate while impregnating the ink. A guide pin for rotating and holding the regenerated ink ribbon is planted near this ink pad. The guide pin has an eave to prevent the ink ribbon from coming off. A guide roller that stretches the guide pin and the ink ribbon has guide holes with the guide pin as a fulcrum, and an arc is drawn as the end point so that the ink ribbon comes into pressure contact with the ink pad. A knob is formed on the upper end of the guide roller so that the operator can freely operate it by hand.

[0004]

[Problems to be solved by the device]

 Ink ribbon cassettes of various shapes and sizes are commercially available, and depending on the type, there is a protrusion on the ink ribbon cassette body, and the protrusion abuts the rib on which the ink ribbon cassette of the ink ribbon reproducing device is placed, and the ink ribbon cassette Cannot be installed, or the conventional rib position is unstable because only part of the ink ribbon cassette can be placed, the position of the cassette holder does not match, and the ink ribbon cassette moves during playback, and the ink ribbon cannot be played back. There was something I couldn't do.

[0005]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned conventional problems, and is a case in which a shaft fitted into a power transmission hole of an ink ribbon cassette is projected on the upper surface of the case and a motor as a drive source of the shaft is incorporated. A means for holding the ink ribbon cassette on the upper surface of the housing, a guide pin for rotationally supporting the ink ribbon of the ink ribbon cassette held by the holding means, and the ink ribbon stretched in cooperation with the guide pin. A movable guide roller, an ink pad that applies ink to the ink ribbon by tensioning the ink ribbon between the guide pin and the guide roller, and an ink ribbon cassette mounting base that serves as a holding means for the ink ribbon cassette are deformable ink. It proposes a ribbon playback device.

[0006]

[Action]

 In the present invention, it is possible to select the installation position of the ink ribbon cassette stand, and by using this stand also as a rotation stop for the ink ribbon cassette, it is possible to support ink ribbon cassettes with protrusions and unstable ink ribbon cassettes. The present invention proposes an ink ribbon recycling device.

【Example】

 Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a side view of an ink ribbon reproducing apparatus of the present invention in which an ink ribbon cassette is mounted, and FIG. 2 is a plan view. Inside the housing 1, a motor (not shown) connected to a main shaft for transmitting the power for winding and winding the ink ribbon (not shown) of the ink ribbon cassette 9 is arranged. A shaft end plate 6 corresponding to a plurality of types of shafts for feeding out and winding up the ink ribbon is supported on the upper end portion of the main shaft.

Further, one or more circular holes are formed on the upper surface of the housing 1, and the cassette holder 7 is inserted into this hole. The cassette retainer 7 has an eaves 8 protruding from the upper end of the cylindrical portion for pressing the ink ribbon cassette 9. The eaves 8 is pressed against the upper surface of the ink ribbon cassette 9 and locked to position the ink ribbon cassette 9. it can. The portion on which the ink ribbon cassette 9 is placed is recessed with respect to the installation surface of the ink pad 2 in order to avoid contact with the lower protrusion of the ink ribbon cassette 9, and the recessed surface 10 has a plurality of holes 11 Has been opened. Into this hole 11, columnar protrusions 13 of mounting bases 12 and 18 for mounting and locking the ink ribbon cassette 9 shown in FIGS. Further, a slip stopper is attached to the surfaces of the mounting tables 12 and 18 in order to prevent the ink ribbon cassette 9 from slipping. For this anti-slip, synthetic resin, rubber, etc. can be adopted.

The ink ribbon cassette mounting table 12 has a concave shape as a whole by the tension coil springs 14, 14 and a shaft 15 passing through the inside of the tension coil springs 14. There is a stopper at both ends of this shaft 15, and if one end of the ink ribbon cassette stand 12 is pulled against the restoring force of the tension coil spring 14, it becomes a horizontally long concave shape until the stopper is restricted. Expanding. When the downward columnar projections 13 of the ink ribbon cassette mounting bases 12 and 18 shown in FIGS. 3 and 4 are fitted into the holes 11 of the recess 10 of the housing 1, the upper surfaces of the ink ribbon cassette mounting bases 12 and 18 are the ink of the housing 1. Place it on the same plane as the pad 2 installation surface. Further, since there is only one downward columnar protrusion 13 of the ink ribbon cassette table 12, it is possible to rotate around this columnar protrusion 13. Furthermore, the columnar protrusion 13 of FIG. 3 can be used as a rotation stopper for the ink ribbon cassette 9 by fitting it into the hole 11. If the ink ribbon cassette 9 is inserted into the recess of the ink ribbon cassette stand 12, the restoring force of the tension coil spring 14 will As a result, the ink ribbon cassette 9 is clamped, and it is possible to prevent the ink ribbon cassette 9 from floating during rotation. Depending on the type of ink ribbon cassette, the ink ribbon cassette retainer 7 could not be locked due to its position and thickness. However, the ink ribbon cassette stand 12 as described above can accommodate ink cassettes of any thickness. can do. The ink ribbon cassette 9 may be set diagonally to the extent that it does not hinder the rotation of the ink ribbon.

As another embodiment, FIG. 4 shows an ink ribbon cassette stand using rubber, a rubber-like elastic body and a shaft. The shaft 17 has stoppers at both ends so that it can be extended horizontally in a concave shape against the restoring force of the rubber 16 as in the previous embodiment, so that it can be adapted to any thickness of the ink ribbon cassette. it can. In order to prevent the rotation of the ink ribbon cassette stand, for example, a shaft having a rectangular cross section is used.

In another embodiment, a pressing plate 20 made of a flexible material such as copper or phosphor bronze is fitted and fixed to one end of the ink ribbon cassette holder 19 and the pressing plate 20 is elastic when the ink ribbon cassette 19 is inserted. The ink ribbon cassette 19 can be held by being deformed.

Further, as another embodiment, if columnar protrusions are formed on both ends of a rubber-like elastic body such as rubber or synthetic resin and the columnar protrusions are fitted into the holes of the housing on which the ink ribbon cassette is placed, elastic force will be generated. Can be pressed and fixed.
