LIGHT SOURCE DRIVING DEVICE, OPTICAL SCANNING DEVICE, AND IMAGE FORMING APPARATUS |
摘要 |
A write control circuit includes a first data switching circuit that sets a correspondence relationship between signals from line buffers and input signals to a delay circuitry, based on a signal from a CPU; and a second data switching circuit that sets a correspondence relationship between output signals of the delay circuitry and drive signals, based on a signal from the CPU. This enables a plurality of light emitting sections to be driven properly, regardless of a main scanning direction and an arrangement of a plurality of light spots being in any of CASE-1 to CASE-4 in an optical scanning device.
