A disk device configured in such a manner that, in addition to tilt adjustment, the adjustment of the distance between a disk and an optical pickup can be easily performed. The disk device is provided with a stepping motor () for moving the optical pickup (), a base chassis () to which a spindle motor () for rotating a turntable on which a disk () is affixed is mounted so as to be adjustable in position, a guide shaft () provided to the base chassis () so as to extend in the radial direction of the disk and guiding the movement of the optical pickup () by being in contact with a portion of the optical pickup (), a sub guide shaft () provided to the base chassis () and guiding the movement of the optical pickup (), a tilt adjusting section () for adjusting the relative distance between the sub guide shaft () and the base chassis (), and a turntable adjusting section () for adjusting the radial angle, the tangential angle, and the height of the spindle motor () relative to the base chassis ().

Disk device

An optical disc device is disclosed. In the optical disc device, a cam portion configured to include a holder that is supported on the outside of a cam member to turn and move vertically is provided in a position that is in vicinity of a tray being supported by elevator cam gears. In disc loading/ejecting operations, the cam portion is turned and a projecting portion pushes down a tray projecting portion of the tray, so that a space S if formed between the tray and the disc. Since the tray is shaped into a closed circular tray, a rigidity of the tray can be ensured and also the space used to avoid a contact between a projecting portion on a lower face of the disc and a surface of the tray can be provided by bending the tray.

Optical disc device having a plurality of trays with a cam for contacting the plurality of trays

A disc device capable of achieving a slimming down of a tilt adjusting portion is provided. A tilt adjusting memberof a tilt adjusting portionmoves an optical pickup driving portionalong a guide faceto adjust a light beamemitted from an optical pickupsuch that an optical axisis set perpendicularly to a disc. Since the tilt adjusting memberis moved in a direction oblique to the guide faceand a direction perpendicular to the optical pickup driving portion, an amount of movement of the tilt adjusting membercan be reduced smaller than a necessary amount of tilt adjustment of the optical pickup driving portionand also a slimming down of the tilt adjusting portioncan be achieved. In this case, since a top end portion of the optical pickup driving portionis energized by an energizing memberto come into contact with the tilt adjusting memberand the guide face, this top end portion of the optical pickup driving portioncan be adjusted to come close to and go away from the discwithout wobbling and rattling.
