In a CD player, a connection tray is mounted in a cabinet in a shiftable manner among a retracted position, a first projected position, and a second projected position. The connection tray has an upper tray and a lower tray. The upper tray has a first connector, a second connector, and a stopper. The lower tray has an unlock button, a movable plate, and a lock plate. A lock bracket is formed with a lock depression into which a lock boss is inserted to lock the connection tray in the first projected position, in shifting the connection tray forward from the retracted position. In a front surface of the lock bracket, a lock projection is formed. The lock projection receives the lock boss to lock the connection tray in the second projected position.

A disk-chucking device comprises a pressing member including a circular groove which is provided around a circumference of the clamp member, and a clamping member mounted on a turning plate for clasping the circular groove of the pressing member. The turning plate provides a through hole at the center thereof which allows the pressing member passing through, and a plurality of first notch portions disposed along the circumference of the through hole. The turning plate is slidably connected to a mounting board through the clamping member. The turning plate can rotate with respect to the mounting board to move the pressing member vertically. Thus, the pressing member can be pressed onto and removed from a disk support of the displayer according to the rotation of the turning plate. The present disk-chucking device can chuck the disk securely regardless of the position of the disk player.

A disc drive apparatus (1) capable of reading/writing discs (100; 200) of different sizes comprises: a first rotary drive device (30) for holding and rotating a first-type disc (100) in a first play position; and scanning means (40) for scanning a surface (103) of the rotating first type disc (100) in its play position. The disc drive apparatus (1) further comprises a second rotary drive device (50), arranged opposite the scanning means (40), for holding and rotating a second-type disc (200) in a second play position. Said scanning means (40) are also capable of scanning a surface (203) of the rotating second-type disc (200) in its play position.

An optical disk drive includes: a tray having first and second loading portions for respectively loading a first disk and a second disk of a smaller diameter than the first disk, the first and second loading portions having different heights, first and second inclined portions formed obliquely outward and inward on edges of the first and second loading portions, respectively. The optical disk drive further includes: a spindle motor having a turntable supporting the disks on a plane thereof, the motor rotating the disks and approaching/departing from the disks; and a clamp rotatably supporting the disks on the other plane thereof, wherein the clamp can approach the disks due to a magnetic force exerted between the clamp and the turntable as the spindle motor approaches the disks.

Disclosed is a disk adapter for receiving a disk-type recording medium on an inner circumference side thereof, comprising: a main plate portion having a substantially arcuate shape of a central angle of 180° or more; and a supporting portion formed on a half circumference side of the inner circumference of the main plate portion for supporting the disk-type recording medium mounted on the disk adapter. Consequently, mounting and removing operations of a disk-type recording medium onto and from the disk adapter are very simple.

A loader tray for eliminating disk vibration and resonance effect has recessions with an opening for placing disks for available for a disk to be read/recorded and hollow parts for balancing the air pressure are provided at the recession of the tray. Therefore, a steady disk can be obtained in a state of high rotation speed and a reading/recording job can be performed effectively in the loader.

An optical disk recording and/or reproducing apparatus records and/or reproduces information on an information record surface of an optical disk loaded thereto. The optical pickup apparatus for the optical disk recording and/or reproducing apparatus is provided with: two types of optical pickups for at least two types of optical disks respectively; first and second guiding rails arranged substantially parallel to each other such that the information record surface of the loaded optical disk is disposed between the first and second guiding rails, for respectively guiding the optical pickups along the information record surface of the loaded optical disk in a radial direction of the loaded optical disk; first and second retracting rails respectively connected to the first and second guiding rails, for retracting thereonto the optical pickups from the first and second guiding rails through linkages with the first and second guiding rails respectively; a rotator frame for holding the first and second retracting rails; and a rotating mechanism for rotating the rotator frame around an axis parallel to the first and second retracting rails and for swapping the first and second retracting rails to each other.

It is an object of the present invention to provide a disc transfer mechanism that includes a simply configured tray to be moved and that is reliable in installing and removing a disc. When a tray (1) is drawn out as shown in FIG. 8(a), a positioning protrusion (33a) of a disc receiving member (23) determines a position at which a disc (34) is placed. The tray (1) is pushed in as shown in FIGS. 8(b) to 8(c) until a central hole (35) in the disc (34) reaches a position over a turntable (9). Subsequently, a disc receiving member (23) moves to the front end of the tray (1) relative to the movement of the tray to the internal end as shown in FIGS. 8(d) and (e) to enable the disc to be installed and removed stably.

A loading mechanism for a compact disk (CD) recording and/or reproducing device, comprising: a motor; a set of gears; a lever plate; a gliding piece; and a CD carrier. Mounting and dismounting of the CD is driven by a combination of a linear and a rotatory movement, allowing the operations of inserting/ejecting and raising/lowering of the CD to be driven by a single motor. The arrangement provides stable movements with minimum vibrations, such that a high reliability of reading and recording data is achieved.
摘要:
An optical disc clamp mechanism that is capable of selectively playing back either of a compact disc or a mini disc. The clamp mechanism includes a circular disc receiving section for contacting a reference surface of either of the compact disc or the mini disc and further includes a magnetic clamp unit for clamping the mini disc by magnetic attraction with a magnetically attractable member of the mini disc. A first conical or spherical taper cone portion for engaging the center hole of the mini disc is mounted to the disc receiving section and a second conical or spherical taper cone portion for engaging the center hole of the compact disc is mounted to the disc receiving section. The first taper cone portion is located inwardly of the second taper cone portion and protrudes from the second taper cone portion in the axial direction. The magnetic clamp unit further includes a stopper element for preventing detachment of the first and second taper cone portions from the disc receiving section. Accordingly, the optical disc clamp mechanism independently affects the centering of a mini disc and a compact disc to allow either of the discs to be centered.
