Disk magazine and disk loading device

Abstract: A disk magazine (1) for containing a plurality of disks (8) includes a detachable lid (4) for covering its disk outlet (2), enabling to take out the disks, a plurality of disk-pushing means (6) for pushing out the disks (8) one by one through the outlet (2). This prevents dust from entering or disks from popping out the magazine when the disk magazine (1) is not in use. A compact recording/reproducing apparatus provided detachably with the disk magazine (1) can be constructed if a single motor (85) is used to drive a pushing lever (87) for selectively thrusting the disk pushing means (6) to selectively push said disk (8) out of the disk magazine (1), and disk transfer means for loading the pushed disk (8) onto, or unloading it from, the recording/reproducing drive unit. A pushing lever (87) is connected to a press piece (107) which pushes portions (11a) of magazine slide levers (11) to be pushed, thereby causing discs to be pushed out of the magazine (1).

Disk cartridge for disk player with integrated disk changer

Abstract: A disk cartridge for use with a disk changer wherein various internal members can be assembled by a minimal number of screws or like fasteners, and with a minimal size and thickness, and a disk player with an integrated disk changer wherein an end of a disk drawn in by a drawing-in mechanism does not collide with any member such as a clamper, and a guide need not be moved away when a disk is moved to a position at which it is to be clamped by the clamper. The disk cartridge includes several partition plates each having a pair of spacers formed on the opposite sides thereof and placed one on another to define several disk receiving slits, and a pair of spring plates for resiliently pressing disks in the slits in suitable directions. The disk cartridge is handled on the disk player by a disk discharging device which employs a power converting device, a disk loading device, a disk clamping device and a cartridge ejecting device, all of which are improved.

Chucking device for disk player

Abstract: PURPOSE:To attenuate the vibration of a turn table at a rotating time and to decrease a jitter generated at a disk reproducing time by providing a damper on the turn table for disk loading to be fixed to the shaft of a motor CONSTITUTION:Damper rubber 30 is provided on both upper and lower surfaces of a turn table 10 as the damper to attenuate the vibration at the rotating time of a disk 2 In details, notch parts 10b and 10c, etc, in a prescribed shape are formed to the upper and lower parts of the turn table 10 in a radial pattern with a prescribed interval and between these notch parts 10b and 10c, etc, plural ribs 10d, 10d, are respectively formed Thus, structure is obtained to decrease elasticity in a direction where the shaft 4 of a spindle motor 3 is twisted The damper rubber 30 is outsert-molded in a shape to pad these ribs 10d, 10d, Thus, the vibration at the disk rotating time is attenuated and the jitter at the disk reproducing time is suppressed to be low

Loading/unloading device for disk

Abstract: PURPOSE:To stably perform the lifting operation of a spindle motor without generating deviation in the perpendicularity of the spindle motor and dislocation in a shaft center by guiding the spindle motor so as to be lifted coaxially by a sleeve, and lifting the spindle motor by interlocking with the disk insertion/ ejection operation of a disk carrying means CONSTITUTION:The spindle motor 21 is raised by one end of a lever body 70 being turned via a cam mechanism after a cartridge holder is moved rearward horizontally to a position corresponding to the disk loading position by the driving force of a loading motor 50, and is moved upward by the guidance of the sleeve 20 Thus, a turntable 30 is raised with the upward movement of the spindle motor 21, and a disk loaded in a disk cartridge is transferred on the turntable 30, and the disk is held at a rotational position in the center of the disk cartridge by attraction between a disk clamper mounted in the disk cartridge and a magnet on the upper end of the turntable 30

Disk loading mechanism

Abstract: PURPOSE:To enable positioning at a disk hole part and to improve operability by providing a means to detach and engage a disk motor and a disk table and attaching the disk table to a tray so as to be freely rotatably. CONSTITUTION:In an unloading state, a pickup unit 6 is separated from the tray 1 and waits under it and in this state, the disk 4 is set by engaging the disk hole part provided on the center of the disk 4 with the projecting part of the disk table 3. Next, when the disk 4 is placed on the disk table 3 and it is conveyed to a prescribed position inside a cabinet 2, the pickup unit 6 is rotated upward and an engaging member 8 fixed to the rotary shaft of the disk motor 7 and the groove 5 of the disk table 3 are fitted with each other and besides, the disk 4 set on the disk table 3 is pressed so that the disk 4 turns into an operable state.

Small optical disk device

Abstract: PURPOSE:To miniaturize a disk device without providing a specific mechanism by providing a rotary shaft by which a motor to drive an optical disk rotatably can be moved in an axial direction, and moving the rotary shaft in a direction of the disk at the time of holding the disk and in a direction to be separated from the disk at the time of taking out the disk. CONSTITUTION:The hub 24 of a disk loading/unloading mechanism in an optical disk device is fixed at the tip of a spindle shaft 25, and the rotor 29 of a motor is mounted on the shaft 25, and the shaft 25 is supported with a rotary bearing 11 provided at the motor. When an operator loads the disk in driving by pressing a case 21, a lever 16 is pressed, and a cam 12 is pressed leftward, and a ball 14 is raised by the cam 12. Thereby, the hub 24 at the tip of the shaft 25 is engaged with the disk. Also, when a cartridge is taken out, the operator depresses a button 15, and moves the cam 12 rightward, and the shaft 25 descends by the force of a spring 19, and simultaneously, the lever 16 is rotated, and a holder 23 is extruded rightward, then, the cassette can be taken out.
