Abstract

PURPOSE:To arrange so that an ink ribbon may run stably by providing a long heat sink on the same surface as a ceramic on the upper part of the ceramic with a heating resistor fixed so as to enable the heat sink to be located above the upper edge of an ink ribbon. CONSTITUTION:A thermal head 15 consists of a heating resistor 27, a ceramic part 28 containing wiring, etc. and a heat sink 29. The heat sink 29 is provided all along on the same surface as a ceramic at the upper part of the ceramic part 28. In addition, it is so designed that the upper part of the heat sink 29 may form above the upper edge of an ink ribbon 16. This printer uses the lower half of the ink ribbon 16 for printing and besides, uses it twice by reversing a ribbon cassette. Thus it is possible to enable the ink ribbon to run stably and prevent a missing print due to ribbon heaveup and other reasons and an increased winding load on account of a ravelled ribbon. Further the application of the costly ceramic part can be minimized.

An ink ribbon 16 is housed inside. The carriage 5 is driven by a timing belt 1 by a carriage motor 8.
In the figure, it is configured to be movable in the left and right direction via the arrow 0. The line feed motor 11 transmits driving force to a gear (1112) connected to the shaft of the platen 18 to feed the paper 14. Paper can also be fed in the same way by turning the platen knob 13 by hand. 19 is a paper guide. Yes.Release lever 20
By moving the paper back and forth, the paper pressing roller 17, which is slidably arranged on the shaft 3, can be pressed against the paper surface.
It has a structure that allows it to be moved away from the paper. Reference numeral 6 is a home position sensor, and reference numeral 9 is a flat cable for passing weight through the thermal head 15 and the like. This printer uses a unidirectional printing method that prints only when the carriage 5 moves to the right; when it moves to the right, it winds up the ink ribbon 16, and when it moves to the left, it winds up the ink ribbon 16.
Do not wind it. Further, the carriage motor 8, line feed motor 11, home position sensor 6, thermal head 15, etc. are controlled by a controller 21.

The thermal head 15 is composed of a heat generating resistor 27, a ceramic section 28 including wiring, etc., and a heat sink 29. In this printer, the lower half of the ink ribbon 16 is used for printing, and by reversing the ribbon cassette 7, the ink ribbon 16 can be used twice. As shown in FIG. 3, in the conventional thermal head 15, when printing,
Only the [] side of the ink ribbon 16 is pressed, and stable running of the ink ribbon 16 is difficult due to unbalanced suppression. In the thermal head 15 of the present invention shown in FIG. 2, the ink ribbon 16 is pressed not only by the ceramic part but also by the heat sink 29, and the entire ink ribbon 16 is uniformly suppressed.

これによりインクリボン１６の安定走行が実現される。As a result, stable running of the ink ribbon 16 is realized.
