ABSTRACT:
A data signal which is output from a latch circuit (12) having five stages of latch circuits each storing one-line data signal to a drive circuit (16) for lighting each light emission unit is selected by a selection circuit (15) according to a 9-bit correction data signal for each of the light emission units stored in a Y-position correction data storage circuit (13). Thus, lighting timing of each light emission unit is adjusted, thereby performing printing having a preferable linearity.
