Abstract

In order to improve the traveling stability of an ink ribbon, a thermal head having a structure in which an edge of one surface of a substrate, lying downstream with respect to the traveling direction of an ink ribbon, is formed so as to have a curved shape projecting most downstream with respect to the traveling direction of the ink ribbon at the widthwise central portion of the ink ribbon or a thermal-transfer line printer having a structure in which a separation member separating the ink ribbon from a paper sheet and a tension-exerting section are independently formed from each other is provided.

Description

technical field

[0001] The present invention relates to a thermal line head and a thermal transfer printer suitable for improving the movement stability of an ink ribbon. Background technique

[0002] Existing known thermal transfer line printers, through the wide ink ribbons such as ink film and ink plate and the format paper as the recording medium, the line format with the length corresponding to the vertical or horizontal printing range of the format paper is made The thermal head is docked with the platen, and in this docked state, while conveying the ink ribbon and the format paper, based on the printing information (recording information), selectively drive the printers arranged in the longitudinal direction of the line thermal head. Printing (recording) is performed by duplicating the ink of the ink ribbon on the form by printing a plurality of heating elements with a width (recording width) and heating them.

[0003] Below, refer to Figure 19 to Figure 21 , to des...
