Abstract: The present invention is to provide a pickup feed device to accurately position an optical pickup in place with miniaturization. The pickup device includes a lead screw attached to a movable chassis, a pickup portion, a rack member, a torsion coil spring, a projection portion, and a recess portion. The pickup portion has a case receiving the pickup. The rack member is fixed to the case. The rack portion disposed on a rack one end portion and a case one end portion are engaged with the lead screw. A rack another end portion has the abut portion abutting an inner edge portion of the movable chassis. The torsion coil spring urges the abut portion toward a case another end portion. The projection portion is disposed on the abut portion and the recess portion is disposed on the case another end portion.

Abstract: A supporting mechanism for movably supporting a member to be supported along a supporting shaft, comprises supporting members and a pressing device. The supporting members are provided on the member to be supported. Each of the supporting members comes into contact with the supporting shaft on at least two contact points so as to be movable on the supporting shaft. The at least two contact points are apart from each other. The pressing device presses the supporting members against the supporting shaft so that the contact points of each supporting member simultaneously come into contact with the supporting shaft.

Abstract: To mount or dismount a recording medium easily, a recording medium playback apparatus includes a main body 3 and a tray 4. The tray 4 includes a tray body 5, a pickup portion 6 and a lock mechanism. The pickup 6 is mounted on the tray body 5 to be moved freely against the tray body 5. The lock mechanism can move freely between a permissible position and a limited position. The tray 4 can move between a playback position and a mount position. When the tray 4 is in the playback position, the lock mechanism is positioned in the permissible position. When the tray 4 is in the mount position, the lock mechanism is positioned in the limited position.

Abstract: A pickup device has a light source, an objective lens for converging rays of light emitted from a light source onto a recording medium, a lens holder for holding the objective lens, and supporting element for movably supporting the lens holder. The pickup device is uniquely featured in that a part of the objective lens and a part of the lens holder are movable relative to each other so as to adjust an inclination of an optical axis of the objective lens.

Abstract: There is provided a disc player which comprises a base section, a loading section linearly movably mounted on the base section, a rotary tray rotatably mounted on the loading section for receiving a plurality of discs, a driving motor provided in the loading section for producing a driving force, a turn table provided under the rotary tray. The disc player further includes a first operating mechanism for transmitting a driving force from the driving motor to the rotary tray, and for moving down the turn table when the rotary tray is to be rotated, a second operating mechanism for transmitting a driving force from the driving motor to said loading section to cause the loading section to linearly move with respect to said base section, a change-over for selecting an operation of the first operating mechanism or the second operating mechanism.
