<p>PURPOSE:To provide an inexpensive print head by simplifying an external wiring and an external control mechanism. CONSTITUTION:A latch signal sent from outside is input to a driving control circuit X1 on the substrate. As a result, a plurality of strobe signals are generated inside, which are output to a gate circuit 4. An array of light emitting elements of a luminescent body 8 is driven per every block by a signal from the gate circuit. Accordingly, it becomes unnecessary to control the strobe signal outside, thus eventually dispensing with a connecting wiring between the outside and the substrate.</p> |
