  • Patent number: 7350221
    Abstract: A height adjustment device is provided that has a first chassis having an adjustment hole, an adjustment screw that stands when threadedly engaged with the adjustment hole in the first chassis, a second chassis locked by the adjustment screw so as to have a preset separation distance from the first chassis, and biasing means for biasing the first chassis and the second chassis in the direction of attaining separation therebetween. The adjustment screw has a tip portion for forming a female thread in the adjustment hole when rotated and inserted into the adjustment hole, a threaded portion having a male thread threadedly engaged with the female thread formed by the tip portion, and a head portion for locking the second chassis against the direction of biasing by the biasing means, in a nearly linear state.

  • Patent number: 7162726
    Abstract: A disk apparatus of the present invention, in which a cartridge accommodating a disk-like recording medium and having an opening opened or closed by a shutter member is loaded to the disk apparatus, includes a loading chassis; a cartridge transporting member provided on the loading chassis for transporting the cartridge from a removal position to a play position; a traverse unit for carrying a pickup for recording or reproducing a signal onto or from the disk-like recording medium; a traverse transporting member provided on the loading chassis for transporting the traverse unit from a standby position to the play position; and a driving section provided on the loading chassis for driving the cartridge transporting member and the traverse transporting member. The cartridge transporting member and the traverse transporting member can slide in a direction of transporting the cartridge. One of the cartridge transporting member and the traverse transporting member is disposed on the other.

  • Patent number: 7013472
    Abstract: In an optical disk apparatus in accordance with the present invention, a tilt chassis (3, 201) to which a main shaft (6) and a sub shaft (7), being parallel with each other and serving to guide the movement direction of an optical pickup (50), are secured is disposed rotatably with respect to a traverse chassis (4) to which a spindle motor (2) is secured, and the tilt chassis (3, 201) is configured so as to be tilt-adjustable with respect to the traverse chassis (4) by tilt adjustment means having two tilt adjustment portions (30, 31), whereby tilt adjustment work for adjusting the movement face of the optical pickup so as to be parallel with the recording face of an optical disk is made easy.

  • Patent number: 6141314
    Abstract: An optical disc drive apparatus including a main tray having a stack of subtrays mounted thereon and movable between withdrawn and inserted positions. When the main tray is moved to the inserted position, the subtrays stacked thereon are held at a stand-by position and a selected one of the subtrays is ready to be drawn towards a loaded position so that an optical disc resting on the selected one of the subtrays can be clamped in position and optically read out.
