DRIVING IC AND OPTICAL PRINT HEAD

摘要

PROBLEM TO BE SOLVED: To provide a driving IC for correcting the shift of focus position caused by mechanical or optical curve of an optical print head, and an optical print head comprising the driving IC. SOLUTION: Data signals being delivered from a latch circuit 12 having latch circuits each storing a line of data signals in five stages to a drive circuit 16 in order to light each light emitting part are selected by a select circuit 15 depending on a 9 bit correction data signal stored for each light emitting part in a Y position correction data storing circuit 13. Good linearity is ensured in printing by regulating the lighting timing of each light emitting part.
