    摘要： A shift register is provided in which leakage of charges from a voltage at a set node is prevented to stabilize an output from a stage. The shift register includes stages for sequentially outputting scan pulses. An nth one of the stages includes a node controller for controlling voltages at nodes, and an output unit for outputting any one of a corresponding one of the scan pulses and a first discharging voltage according to the voltages at the nodes. The nodes include set and reset nodes. The node controller of the nth stage includes a first switching device controlled by a voltage supplied to the reset node for supplying a second discharging voltage to the set node, and an inverter circuit controlled by a voltage supplied to the set node for supplying any one of a charging voltage and a third discharging voltage to the reset node.

    摘要： A light scanning unit including a light source unit emitting a collimated light beam, and a beam deflector deflecting and scanning the collimated light beam and having a mirror surface that oscillates, a light scanning method and an image forming apparatus employing the light scanning unit are disclosed. The light source unit may be made to oscillate synchronously with the oscillation of the beam deflector so that the incident angle of the collimated light beam on the beam deflector changes in synchronization with the oscillation of the beam deflector, thereby allowing an increase of the maximum deflection angle of the light beam deflected and scanned by the beam deflector.
