  • Patent number: 7562373
    Abstract: A disc apparatus includes a chassis, a drive unit driven by a motor to be moved upward/downward in a prescribed direction, and a pick-up unit having a pick-up and driven by the motor to be moved in a direction orthogonal to the direction of upward/downward movement of the drive unit. The pick-up unit has an interlocking piece, and the chassis has an interlocking portion that can be interlocked with interlocking piece. In the disc apparatus, the interlocking piece provided in the pick-up unit is interlocked with the interlocking portion provided in the chassis when the drive unit is in a lowered state, whereby the pick-up unit is locked into the chassis. Therefore, reduction in the number of components and in the size of the apparatus becomes possible, and the lock mechanism of the pick-up unit can be formed in a simple structure.

  • Patent number: 7406700
    Abstract: A deck is formed integrally on a front side of a drive chassis. As the drive chassis is moved upward, a disk is mounted on a turntable. The disk is rotated at high speed by a spindle motor, and an optical pick up is reciprocatingly moved along a guide rail and a guide shaft, and a lens holder is moved in focusing directions and tracking directions. Laser light is projected onto the disk through an objective lens so as to read information recorded on the disk. Vibration damping holes are respectively provided penetratingly in the deck substantially between a spindle motor fixing recessed groove of the deck and the guide rail and between the recessed groove and the guide shaft.
