    • A door opening/closing device for an ice dispenser is disclosed. The door opening/closing device includes a DC motor 1 which is rotated in forward and reverse directions, a 2-staged spur gear 3 meshed with a worm gear 2 installed on a driving shaft, a 3-staged spur gear 4 meshed with the 2-staged spur gear 3, and a fan-shaped output gear 5 meshed with the 3-staged spur gear 4 and rotated in forward and reverse directions by interconnection of the motor 1 and the gears 2, 3 and 4. If the output gear 5 is rotated in the forward direction, a rod-shaped boss 5a pushes and rotates a link lever 6a to press a coil spring 8 wound around an opening/closing link 6 and thus open a door 7. If the output gear 5 is rotated in the reverse direction, the coil spring 8 is released from a pressurized state, and the rod-shaped boss 5a rotates in the reverse direction while abutting against the link lever 6a, so that the door 7 is closed without generating impact and sound.

    • Provided are a laser video projector having a multi-channel acousto-optic modulator, and a method and circuit for driving the laser video projector. The laser video projector includes a light generating portion, an optic modulator, an optic combining portion, and an optic scanning portion. The light generating portion emits light to be used to project a video image. The optic modulator modulates the light incident from the light generating portion by using the video signal. The optic combining portion combines modulated light beams emitted from the optic modulator. The optic scanning portion scans light incident from the optic combining portion on a screen. The optic modulator has six or more optic modulation channels so that a plurality of red light beams, a plurality of green light beams, and a plurality of blue light beams incident in a state suitable for optic modulation are simultaneously modulated. Accordingly, limitations in the performance of an optic modulator and an optic scanner can be overcome. Also, a laser video projector can be made small. In addition, the degree of freedom for arranging components increases and the components can be well arranged. Furthermore, a video image of high brightness can be realized.
