ABSTRACT:
A thermal head device operates while a recording medium is fed in its lengthwise direction for line-sequentially printing each image line along its widthwise direction. A platen has a plane tangential thereto to define a level of feeding pass of the recording medium in a printing zone thereof. A plurality of planar head segments are opposed to the printing zone of the platen in staggered relation to each other such that the head segments are arranged along a pair of parallel rows along the widthwise direction of the recording medium. The respective planar head segments have edge portions opposed to each other between the parallel rows in the printing zone, and are slanted relative to the tangential plane such that the respective edge portions are inclined away from the feeding pass of the recording medium.
