printer

Abstract

The present invention provides a printer capable of improving printing quality by preventing unexpected color mixing when a series of information is printed using multiple colors with a simple structure that reduces the number of parts and assembly man-hours . A printer (100) is constituted. In the printer (100), a pair of side frames (101) and a belt plate (110) are connected by a pair of protrusions (501A, 501B) provided on the belt plate (110). The holes (502A, 502B) provided on the side frames (101) are fitted and connected, and the holes (502A) involved in the connection between one side frame (101A) and the belt plate (110) appear to be connected with the print head (103 ) and the embossing member (102) are in the shape of long holes in the longitudinal direction.

Description

technical field [0001] The present invention relates to a printer for printing using an ink ribbon. Background technique [0002] Conventionally, there are printers that perform printing operations using an ink ribbon. In such a printer, printing is switched by switching the position of a tape cassette holding an ink ribbon formed by arranging a plurality of colors in a ribbon shape along the width direction (hereinafter, appropriately referred to as "multi-color ink ribbon"). The color used in the action can realize the printing action based on ink of multiple colors. [0003] Specifically, conventionally, there is a technique of adjusting the inclination of the tape cartridge, which can swing using the fulcrum as a fulcrum, relative to the platen in stages along the direction in which the colors on the multi-color ink ribbon held by the tape cartridge are arranged. Angle, thereby switching the color used in the printing operation (refer to the following patent document 1...

AI Technical Summary

Problems solved by technology

[0013] However, the prior art described in the above-mentioned Patent Document 1 or Patent Document 2 has the problem that the structure for inclining the tape cassette is complicated.

In addition, the conventional technology described in the above-mentioned Patent Document 3 has a problem that the spool and the tape cassette are connected in a state where the flexure portion is bent, and therefore the spool and the tape cassette are disconnected due to friction between the spool and the tape cassette. The contact position of the box becomes high temperature, which sometimes causes plastic deformation

[0014] In addition, the prior art described in the above-mentioned Patent Document 3 also has the following problem: Since the flexure is realized by providing slits on the outer peripheral surface of the spool, the strength of the spool (especially the flexure) is poor.

Therefore, in the conventional technology described in the above-mentioned Patent Document 3, for example, when the ink ribbon is caught or the like and the ribbon lock occurs when the ink ribbon is drawn out and taken up, the tape spool may be damaged.
