Printer

Abstract

The present invention discloses a printer capable of reducing twisting of an ink ribbon. The printer includes a printing unit having a printing head and a platen positioned opposite the printing head,the printing head being configured to print on a print medium that is fed between the printing head and the platen, a ribbon holding shaft configured to hold an ink ribbon before printing that is wound thereon, a ribbon winding shaft configured to wind and collect the ink ribbon after printing, and a pair of guide shafts provided along a feeding route of the ink ribbon between the ribbon holdingshaft and the ribbon winding shaft to erect the ink ribbon, wherein at least one of the pair of guide shafts has a tilt adjuster that changes a tilt of the ink ribbon in a width direction.

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.
