Abstract

PURPOSE:To prevent the formation of stepped difference in the printing of each group of a plurality of heating elements of the thermal head, and to improve the quality of printing of a segment in the width direction of recording paper by dividing the heating elements into two or more of groups and disposing respective group while being displaced in the carrying direction of recording paper. CONSTITUTION:Both resistance heating elements 8a of a block D and the resistance heating elements 8b of a block E are arranged in one row in the width direction of recording paper 3, but the block E is disposed while being displaced to the side in the carrying direction of recording paper lower than the block D only by a distance H. Accordingly, when the block D and the block E are conducted alternately while carrying recording paper 3, the block D is printed, and a distance that recording paper 3 is carried and the displacement H are equalized until printing by the next block E, thus also printing the segment extending over both blocks without stepped difference.

While conveying the recording paper (3) in the direction of arrow C by sandwiching the recording paper (3) between the roller (1) and the thermal head (4), the resistance heating elements (8)... When the current is selectively applied to the electrodes, a record as shown in FIG. 4 can be obtained. However, due to thermal or power supply capacity issues, it is not possible to energize all segments at the same time.
into two blocks (D) (E) in the width direction of the recording paper (3).
), and in the case of the recording example in Figure 4, the energizing period of block ) precedes the energizing period of Glock (E), and blocks (D) and (E) are alternately energized. or be enabled. Therefore, when printing with the conventional thermal head (4), a step G occurs between groups (2) and (E), so a line in the width direction of the recording paper (3) that spans both blocks (D) and (E) This results in a significant drop in print quality.

、以下本発明の一実施例を第５図に基づいて説明する。Therefore, the present invention divides a plurality of resistance heating elements into two or more groups, a basic group (2) and a predetermined number of rear groups located on the downstream side of the basic group in the conveyance direction of the strip recording paper. By arranging the resistance heating elements of the groups on the same plane in the direction [recording paper width direction] that intersects the conveyance direction, step G will not occur even when the energization period is alternated as in the conventional case. An embodiment of the present invention will be described below with reference to FIG.
