Abstract
A thermal line head device operates while a recording medium is fed in a vertical direction for printing dots line-sequentially along a horizontal direction according to bit image data corresponding to dots. A plurality of longitudinal head segments have a plurality of heating elements effective to print dots according to the corresponding bit image data, and linearly arranged along a longitudinal edge portion of the segment and deviated from a longitudinal center portion of the segment. The head segment are arranged in staggered relation along upstream and downstream rows such that the longitudinal edge portions of segments are opposed adjacently to each other in parallel between the rows so that the heating elements are linearly arranged in the horizontal direction between the rows a given vertical spacing. A line memory stores bit image data and distributes the stored bit image data to the heating elements in synchronization with vertical feeding of recording medium through the given vertical spacing.
