Driving IC and optical print head

摘要

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.
