Abstract: A disk device in which a precut portion of sub cam plate and a protruding portion of locking plate are made in a slanted shape and at the same time the sub cam plate is rotated by a pressure when the protruding portion is inserted into the precut portion.

Abstract: A disc player includes a disc holding/separating mechanism which holds the plurality of discs concentrically and which separates the selected disc from the remaining discs; a turntable; a pickup; a playback base which supports the turntable and which moves toward and away from the disc holding/separating mechanism; a clamper which secures the selected disc to the turntable; a damper arm which supports the clamper and which moves toward and away from the disc holding/separating mechanism; a translating mechanism which supports the playback base and the clamper arm and which moves toward and away from the disc holding/separating mechanism; and a control mechanism which controls motions of the playback base, the clamper arm and the translating mechanism in such a way that, when the selected disc is put on the turntable by the disc holding/separating mechanism, the turntable is placed at a first position, which is located on a central axis of the plurality of discs held by the disc holding/separating mechanism, a

Abstract: A drive-force transmitting mechanism includes a drive disk and a driven disk that are rotatable about an axis. The driven disk has two diametrically opposing engagement portions. The drive disk has two levers pivotally mounted thereon, each lever having a clutch pin formed thereon. The two disks are disposed so that the levers are sandwiched between the two disks. The levers are operatively coupled through a coupling member such that rotation of one lever is transmitted to the other. A cam member has a groove that guides a pin member of one lever such that when the drive disk rotates through a first angle, the pins move toward the axis to engage the engagement portions to transmit rotation of the drive disk to the driven disk, and when the drive disk rotates through another angle, the pins move away from the axis to disengage from the engagement portions.

Abstract: An MD 107 is feed to a fixed position in a device by a case-stored recording medium disk loading mechanism having a slit mechanism 125, an MD holder feeding arm 108 and the like. The disk 107 is loaded onto a turntable 131. A drive plate 101 is provided which is driven in a coupled manner and refuges a non case-stored recording medium disk loading mechanism, which has a CD clamp 104 and a CD adapter 106, to a position which does not interfere with the loading of the MD 107 onto the turntable 131.

Abstract: A compatible disk device includes: a base; a first turntable disposed on the base for transmitting a rotational force to a first disk; a second turntable for transmitting a rotational force to a second disk; a retaining arm for retaining the second turntable with a play; a support shaft disposed on the base in a position separated from either the first disk supported by the first turntable or the second disk supported by the second turntable; and a sub-base attached pivotally to the support shaft, the sub-base supporting the retaining arm to be rotatable in a plane parallel to a disk surface of the first disk or the second disk and to be elevated in an axial direction of the support shaft.

Abstract: A disk device is includes first support shaft which supports a retaining arm, retaining a second turntable, to reciprocate vertically and a second support arm which supports the retaining arm to rotate and refuge horizontally so that the second turntable which supports a second disk which is not stored in a cartridge and which transmits a rotational force to a second disk can be loaded and separated from a first turntable which supports a first disk and which transmits a rotational force to a first disk.

Abstract: A disc player for containing a plurality of discs and playing back a disc selected therefrom, comprises a disc holding/separating mechanism which holds the plurality of discs concentrically and which separates the selected disc from the remaining discs to form a first space below the selected disc; a turntable; an optical pickup; a turntable support mechanism which supports the turntable and which moves between an outside of the discs held by the disc holding/separating mechanism and the first space; a disc carrier mechanism which holds and conveys the selected disc between the disc holding/separating mechanism and the turntable; a clamper which secures the selected disc to the turntable; a clamper support mechanism which supports the clamper and which moves between an outside of the discs held by the disc holding/separating mechanism and a second space formed above the selected disc; and a control mechanism which controls motions of the turntable support mechanism and the clamper support mechanism.

Abstract: A bearing (4) is mounted on a base (1) to retain a portion of the shaft (6) ranging from near a lower end portion to near an upper end portion, and a rotor housing (10) is provided with a rotor base (11) disposed at a level lower than that of an optical pickup (13) with a magnet (9) being provided on an inner peripheral surface, and a rotor boss (12) formed separately from the rotor base (11). The rotor boss (12) has a smaller outer radius than the outer radius of the rotor base (11) and is fixed on the rotor base (11) so that a side face is opposite to a side face of the optical pickup (13). Thus, it is possible to prevent run-out of the shaft (6) and to downsize the device with a simple structure. Furthermore, it is possible to use components 1, 2, 5, 9, 11 and the like in common with thin motors used with other types of device and thus manufacturing costs are greatly reduced.
