printer

Abstract

The invention discloses a printer, which can reduce the meandering of the color ribbon. The printer comprises: a printing head and a platen roller arranged opposite to each other; The printing section where the printing head performs printing, the ribbon holding shaft on which the ink ribbon before printing is wound, the ribbon take-up shaft that winds and recovers the ink ribbon after printing, and the ribbon holding shaft and all The conveying path of the color ribbon between the ribbon take-up shafts is set, and a pair of guide shafts for the color ribbon are erected, wherein at least one of the guide shafts in the pair of guide shafts has a function to change the inclination of the color ribbon in the width direction Tilt adjustment mechanism.

Description

[0001] This application claims that the Japanese application with the filing date of July 04, 2017 and the application number of JP2017-131351 is the priority, and cites the content of the above application, and its disclosure content is incorporated herein by reference. technical field [0002] Embodiments of the present invention relate to a printer. Background technique [0003] Currently, in printers such as label printers, a thermal transfer type thermal printer in which ink applied by a thermal printhead is transferred by melting ink applied to a thermal ribbon is widely used. In such a printer, the ink ribbon is stretched over the ribbon holding shaft and the tape take-up shaft, and the ribbon is fed while being rotated by rotating one end of the take-up shaft with a drive motor. That is, the take-up shaft is a cantilever mechanism whose only one end is driven by a drive motor. In addition, in such a printer, there may be a phenomenon that the ink ribbon meanders alo...

AI Technical Summary

Problems solved by technology

In addition, due to the above-mentioned cantilever mechanism, if the mounting angles of the tape take-up shaft and the tape holding shaft are slightly different, the tape tends to meander due to deviation from one side.

Moreover, when the ribbon snakes, the printing quality will be affected due to the distortion of the ribbon at the transfer position where the thermal print head abuts against the ribbon.

[0005] As the prior art, although there is disclosed a technique related to a mechanism for adjusting the tension of the ribbon between the take-up shaft and the delivery shaft, the meandering of the ribbon cannot be eliminated.
