<p>PURPOSE:To eliminate rework due to a deficient luminous quantity of a dot of a LED array. CONSTITUTION:Light emission is implemented by correction data for a latch signal generating period. For the purpose, a correction section 24 is provided and correction data in a storage element 28 are fed to an analog switch of an output control section 22 in response to a latch signal from an LA(-). As a result, as to dot whose luminous quantity is deficient, the light emission is applied to the dot for a latch signal generating period in addition to a strobe signal generating period, the light emission time is extended and the necessity of rework due to deficient luminous quantity is reduced.</p> |
