Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to an ink ribbon used for a dot printer, particularly an endless type used ink ribbon, which has been discarded as used after applying new ink to the used ink ribbon. The present invention relates to an ink ribbon reproducing apparatus suitable for reproducing an ink ribbon.

[Related Art] Conventionally, an ink ribbon used in a dot printer and having a reduced print density has been usually discarded. However,
Except for the ink part, the ribbon and cassette case are of course unbearable enough to withstand use, and as a proposal for reuse of the ink ribbon, Japanese Utility Model Publication No. 55-33715,
No. 57-16364 is known.

[Problem to be solved by the invention] Japanese Utility Model Application Laid-Open No. 55-33715 as a conventional technique described above
The screw must be loosened to secure the ink refill to the device during use, it takes time for the ink to penetrate the pad, and if the ink has excessively penetrated the ink pad of the ink refill, the ink Since the amount cannot be adjusted and the felt is not movable, there is a disadvantage that the ink ribbon comes into contact with only a part of the felt and is worn and deformed. 57-57
No. 16364 requires only extra ink that is not used for application because ink only spills in an open container and poor storage conditions cause ink to spill or change properties and the roller must be immersed in ink There was a problem.

[Means for Solving the Problems] Ink ribbon cassette holding means provided to face the ink ribbon cassette on the upper surface of the housing, and corresponding to the power transmission holes of a plurality of types of ink ribbon cassettes near the ink ribbon cassette holding means. A drive shaft provided with a shaft end plate to be protruded, a housing containing a motor as a drive source directly connected to the drive shaft, and an ink ribbon contained in an ink ribbon cassette held by the holding means are fed and slidably held. A guide pin, a guide roller for extending or loosening the surface of the ink ribbon slidably held by the guide pin on an ink pad impregnated with ink, and an ink pad built in the ink pad cartridge. A guide for guiding the ink ribbon to a position where the surface of the ink ribbon contacts the ink pad. In the ink ribbon reproducing apparatus provided with the ink hole, after the ink ribbon of the ink ribbon cassette is held by the guide pin, the ink ribbon cassette is held by the cassette holding means, and the guide roller is moved according to the guide hole. The ink pad impregnated in the ink pad cartridge is disassembled by applying the ink impregnated in the ink pad to the ink ribbon by moving the motor to a predetermined position and rotating the motor. Another object of the present invention is to provide an ink ribbon reproducing apparatus in which an ink pad cartridge is detachably disposed on an upper surface of a housing of the ink ribbon reproducing apparatus.

[Operation] In the present invention, the ink ribbon cassette is held in hand, the ink ribbon can be stretched between the guide pins and the guide rollers without touching the ribbon, and the ink pad is exchangeable, so that the ink is ready for coating. This is an ink ribbon reproducing device in which the pad cartridge comes out simply by being fixed to the housing with one touch, and rotation of the ink pad prevents wear of only a part of the ink pad.

Embodiment An embodiment of the present invention will be described with reference to the accompanying drawings. First
The figure is an external perspective view of the ink ribbon reproducing apparatus of the present invention.
The drawing is a perspective view of the ink pad cartridge, FIG. 3 is a sectional view of the ink pad cartridge, and FIGS. 4 to 11 show other embodiments. A motor (not shown) connected to a main shaft 7 for transmitting power for feeding and winding the ink ribbon of an ink ribbon cassette (not shown) is disposed inside the housing 1. At the upper end of the main shaft 7, shaft end plates 8 corresponding to a plurality of types of shafts (not shown) for feeding and winding the ink ribbon are rotatably supported by pins. In the ink ribbon cassette, two rectangular holes 12 are formed in the upper surface of the housing 1, a rail 13 is passed through the holes 12, and a cassette holder 14 is slidable on the rail 13. Cassette holder
14 and 14 are arranged so as to face each other in a U-shaped section, and are adapted to move according to the size of the ink ribbon cassette.

An ink pad 15 for refilling the ink ribbon to be reproduced with ink is rotatably supported at the end of the housing 1 opposite to the cassette retainer 14 so as to rotate while impregnating the ink. A guide pin 3 for slidably holding an ink ribbon to be reproduced is planted near the ink pad cartridge 2.
The guide pin 3 is formed with an eave so that the ink ribbon does not come off. The guide hole 5 is arranged so that the guide pin 3 and the guide roller 4 which stretches the ink ribbon have the guide pin 3 as a fulcrum, draw an arc as the extreme end point, and press the ink ribbon against the ink pad 15. At the upper end of the guide roller 4, the operator can freely operate by hand.
A knob 4a is formed. The guide roller 4 is bent at the end of the guide hole 5 and is provided with a spring so as to be locked.

The spacer 16 of the hollow shaft 17 having a diameter slightly larger than the hole diameter is pressed into the hollow ink pad 15 containing the coating ink, and one surface is opened so as to expose a part of the ink pad 15. Put the ink pad 15 in the case
The pin 19 which is the rotation axis of the case is inserted, and two L-shaped projections 18 for fixing are opposed to each other at the bottom of the case, and these projections are inserted into the fixing holes of the housing and rotated by an arbitrary angle. The pad cartridge 2 is fixed.

The method for fixing the ink pad cartridge 2 to the housing will be described as another embodiment. (Fig. 4
FIG. 4 shows an example in which the claw under the case of the ink pad cartridge 2 is press-fitted into a hole on the housing so that the projection at the tip of the claw is hooked and fixed to the housing. FIG. 5 shows an example in which the projection at the rear end of the case and the recess of the housing are fixed together by inserting the projection at the bottom of the case along the groove of the housing. FIG. 6 shows an example in which an inverted T-shaped projection at the lower part of the case is inserted into a hole of the housing, and a claw which is returned by a spring is pulled. FIG. 7 shows an example in which two positioning projections are provided at the lower part of the case and fixed by inserting a lever having a notch with a diameter slightly smaller than the diameter of the fixing projection into the fixing projection. FIG.
This is an example in which a lever having a length slightly shorter than the height of the ink pad cartridge is fixed by being fitted from the left and right. FIG. 9 shows an example in which a projection is formed in the middle of a projection made of a material having good elasticity, a recess is formed on the side surface of the case, and the projection is fixed by fitting into the recess. FIG.
In this example, a protrusion is provided on the side surface of the case, a lever is arranged so as to be hooked from the housing to the protrusion, and the protrusion is hooked and fixed to a claw at the tip of the lever. FIG. 11 shows an example in which slides slightly lower than the height of the case are provided on the left and right sides, and the ink pad cartridge is placed on the housing, and the slides are tightened from the left and right to fix the slides.

[Effects of the Invention] The present invention is configured as described above, so that the ink ribbon cassette can be used with one touch without soiling the operator's hand.
You can set the ink pad cartridge, just replace the ink pad cartridge, the preparation for application is ready,
Even if the type of the ink ribbon cassette is different and the ink application amount is different, it is possible to realize an ink ribbon reproducing apparatus that eliminates insufficient application of ink and excessive application of ink.
