DRIVER DEVICE, PRINT HEAD, AND IMAGE FORMATION APPARATUS |
摘要 |
A driver device scans and drives light emission elements arranged in a branch connection to a common terminal using scan-circuit and data drive portions and clock driver and waveform shaper circuits. The scan circuit portion has scan circuits connected cascadely to one another with output terminals connected to the light emission elements. The driver device outputs first and second clock signals to odd- and even-numbered scan circuits respectively. The light emission elements are sequentially driven from a first to a last scan circuit when the second-clock signal is applied to the first scan circuit. The data-drive portion drives the common terminal. The clock-driver circuit outputs first and second clock pulses with different phases, and a third-clock pulse synchronized with the first and second clock pulses. The waveform-shaper circuit re-shapes the waveforms of the clock signals. |
