Description

technical field [0001] The present invention relates to an ink ribbon cassette used in a line printer, and more particularly, to an ink ribbon cassette capable of improving the positioning accuracy of the cassette when mounted on a printer device, and a printer in which the ink ribbon cassette is mounted on a cassette mounting portion in the printer. Background technique [0002] Conventionally, a printer having a structure in which a desired ink ribbon is inserted is inserted from a cartridge insertion portion formed in a casing of the printer, and the ink ribbon cartridge is assembled to a cartridge mounting portion inside the printer, and the desired ink ribbon is recorded. print data (for example, refer to Patent Document 1). [0003] As shown in FIGS. 3 and 4, an ink ribbon cassette 31, which is an example of a conventional ink ribbon cassette, is formed by fitting a first case 35 and a second case 43. The first case 35 and the second case The body 43 rotatably support...

Problems solved by technology

[0017] However, in the conventional ink ribbon cassette 31, since the first housing 35 and the second housing 43 are respectively formed with the ink ribbon cassette 31 when the ink ribbon cassette 31 is assembled to the printer device, the ink ribbon cassette 31 is assembled to the printer. The positioning holes 42a, 42b and the positioning holes 49a, 49b of the appropriate position of the device, therefore, due to the formation accuracy of the first housing 35 and the second housing 43, the first housing 35 and the second housing 43 are embedded. , the positioning holes 42a, 42b, 49a, 49b are slightly deviated, and as a result, there is a problem that deviations occur in the positioning accuracy of the printer device of the ink ribbon cassette 31.

[0019] In addition, although the peeling roller for peeling the ink ribbon for recording and the recording paper is arranged to be supported by the side wall of the housing in the cartridge assembly part of the printer, sometimes the peeling roller makes it difficult to assemble the tape cassette.
