Abstract: A magnetic disk drive having an elastic member on any one of a cartridge holder and a slide plate, and engaging portions on the other one, in order that the elastic member engaged with the engaging portions will produce a resistance force against the force of coil springs when the slide plate is slid by the force of the coil springs.

Abstract: A disk player has a disk cartridge for being loaded thereon, and accommodating a disk-type recording medium. The disk cartridge has a shutter arranged thereon, for performing slide-opening/closing in order to expose an information surface of the disk-type recording medium. The disk player is comprised of a carrier mechanism for carrying the disk cartridge to an information regenerating location and an information recording location, and a shutter sliding mechanism for slide-opening/closing the shutter. The shutter assumes an intermediate position of sliding when the disk cartridge is located at one of the information regenerating location and the information recording location, and assumes a terminal position of sliding when the shutter is located at the other one of the locations. The disk player also includes a driving mechanism comprised of an engaging element and an engaged element which is separated from the engaging element when the information recording mechanism is not driven.

Abstract: A disk recording device has inside a cabinet a mechanical deck comprising an inner holder for horizontally holding therein a cartridge containing a disk, a chassis movable toward and away from the inner holder and provided with a pickup for projecting a beam on the disk, and an outer holder provided over the inner holder and slidable along the direction of insertion of the cartridge. The inner holder is fixed to the cabinet through holes and cutouts formed in the chassis, and the chassis is movable upward and downward relative to the inner holder. A space for accommodating the pickup is formed between the lower surface of the chassis and the bottom surface of the cabinet when the chassis is in a completely lowered position.

Abstract: A plurality of projected pieces 213 are provided on the surface of a main chassis 210 that is opposed to an eject plate 220 in such a manner that the projected pieces are adapted to guide sliding motion of the eject plate in contact therewith. The main chassis has first openings 214 formed therein at respective positions close to each projected piece on the main chassis. The first openings allow the sliding motion of the eject plate. First L-shaped members 222 are provided on the eject plate at positions corresponding to the first openings. The L-shaped members are each formed by means of cutting, depressing, and bending to extend from the back surface of the eject plate. Bent portions 222a of the first L-shaped members are passed through the first openings to guide the sliding motion of the eject plate along the back surface of the main chassis.

Abstract: An electronic equipment, such as a tape recorder, having a loading section on one surface for loading a recording medium and a lid for opening/closing the loading section. This electronic equipment includes a lock mechanism for locking the lid in the closed position and an unlock mechanism for unlocking the lid. The unlock mechanism has an operating member extended along one lateral surface of the main body portion of the equipment and other lateral surfaces intersecting this one surface for covering the opening side of a recess formed at a corner of the main body portion. The unlock mechanism unlocks the lid by the operating member of the unlock mechanism being moved along the one lateral surface of the main body portion so that the operating member is partially immersed in the recess.

Abstract: An apparatus for loading a disk cartridge is employed in a portable disk drive so as to move the disk cartridge accommodating a disk to a loading position. The loading apparatus includes a tray to receive the disk cartridge, a link mechanism to support and guide the disk cartridge at a predetermined inclined angle while the disk cartridge is initially inserted into the tray, a positioning unit to position the disk accommodated in the disk cartridge on a spindle motor by pushing an upper rear end portion of the disk cartridge as the disk cartridge is in the final stage of the movement to the loading position, a blocking unit to block the disk cartridge to prevent the disk cartridge, once positioned in the tray by the positioning unit, from being separated accidentally from the tray and a withdrawing unit to withdraw the disk cartridge from the tray.

Abstract: A drive unit (7) of an electronic apparatus drives a first transport mechanism (4) for transporting a memory card (1) between an eject position and an intermediate position, and a second transport mechanism (5) for transporting the memory card (1) between an intermediate position and a play position. The second transport mechanism (5) is coupled to the drive unit (7) by a lead screw transmission (9,14).

Abstract: A locking plate 40 is provided near the front end of a magnetic disk mounted on a magnetic disk drive to prevent downward sliding movement of a disk holder 13. The locking plate is located at a first position between a chassis 11 and the disk holder to lock the disk holder when no magnetic disk is mounted on the magnetic disk drive. When the magnetic disk is mounted on the magnetic disk drive, the locking plate engages with the front end of the magnetic disk and moves to a second position out of the position between the chassis and the disk holder.

Abstract: A movable platform is mounted on opposing guide rails within a disk drive. A head actuator and spindle motor are mounted on the movable platform. The platform moves on the guide rails from a forward position to a rearward position upon insertion of a disk cartridge into the disk drive. As the platform moves toward the rearward position, the elevation of the platform changes in order to bring the spindle motor into engagement with the hub of the disk cartridge. A latch member having a torsion spring and a notched projection is pivotally mounted on one of the guide rails for latching the platform in its forward position when the disk drive is not in use. The latch member locks and holds the platform in the forward and locked position when a shock load is encountered.

Abstract: An optical disk apparatus is provided with a housing having an inlet/outlet port, a tray holder which is swingable inside the housing, with one end as a center, a tray which is slidably held inside the holder and which is pulled out from the holder through the inlet/output port for placement of a cartridge and is drawn into the holder after placement of the cartridge, a spindle motor, located at a position toward which the holder swings, for spinning the optical disk arranged in the cartridge, and a swinging mechanism for swinging the holder to bring the optical disk in the cartridge into engagement with the spindle motor after the tray is received inside the holder.

Abstract: The present invention relates to a rotary disk loading mechanism. A disk loading mechanism according to the present invention includes a recording medium holder which is rotatably supported by a chassis and into which a storage medium such as a mini disk (trademark) or the like is inserted, an eject lever as a rotation operation member disposed on one side of the recording medium holder and movably supported by the chassis, an operation converting means formed of a cam and so on for converting movement of the eject lever into rotation of the recording medium holder, a holder locking member rotatably provided on the chassis and biased by a first springy member, and an engagement portion provided on the eject lever and biased by a second springy member in a predetermined direction to thereby be engaged with the holder locking member.

Abstract: A disk drive capable of preventing an incorrectly inserted cartridge from further advancing in the earliest possible stage of insertion and securing the longest possible stroke of automatic transfer of the cartridge. A slider is provided for transferring a disk cartridge that is being inserted between the mounting and dismounting position and a fully inserted position while moving together with the disk cartridge with respect to a holder for guiding and holding the cartridge. The slider is provided with a projection that faces a specified side portion of the disk cartridge extending in the direction in which the cartridge is inserted and allows the insertion of the cartridge while being slidably fitted in a groove provided on the side portion of the disk cartridge extending in the direction in which the cartridge is inserted when the disk cartridge is being inserted in the correct position.
