<p>PROBLEM TO BE SOLVED: To reduce generation of a level difference in a boundary between adjacent blocks during printing in an LED printer including a plurality of blocks in each of which light is sequentially emitted from a plurality of LED elements.SOLUTION: An LED printer head includes: a plurality of blocks 31 each including a plurality of LED elements 41 arrayed one-dimensionally in a main scan direction; a printer head in which the blocks 31 are arrayed one-dimensionally in the main scan direction; and control means for controlling a predetermined number of LED elements 41 included in each block 31 to sequentially emit light. Light-emitting directions of the LED elements 41 in the two adjacent blocks 31 are opposite to each other.</p> |
