ABSTRACT:
From a latch circuit (12) composed of five stages of latch circuits each storing data signals corresponding to one line, data signals to be fed to a drive circuit (16) to light the corresponding light-emitting sections are selected by a select circuit (15) selects according to correction data, consisting of 9 bits for each light-emitting section, stored in a Y position correction data storage circuit (13). This permits adjustment of the timing with which the individual light-emitting sections are lit and thereby helps achieve printing with satisfactory linearity.
