A rotary knob assembly capable of up-and-down motion is provided. The rotary knob assembly includes a lower case with an oil damper; a rotary sleeve rotatably disposed in the lower case with a connecting hole; a slide cam that moves linearly with respect to the lower case with a pair of cam grooves and a sleeve hole; an elastic member disposed between the slide cam and the lower case; an up-and-down moving sleeve that moves up and down with respect to the rotary sleeve with a pair of up-and-down cams inserted in the pair of cam grooves of the slide cam; a rotary knob that is rotatably connected to the up-and-down moving sleeve; and an upper case connected to the lower case to limit vertical movement of the rotary knob, wherein a moving speed of the slide cam is controlled by the oil damper.

A disk drive including a tray and an opener. The tray includes a disk cartridge mounted thereon and is loaded into and unloaded from a main body. The opener is installed in the main body and elastically contacts a guide formed on the tray. The opener includes a second gear and a first protrusion. The second gear rotates a rotating wheel when in contact with a first gear. The first protrusion formed on a first end of the second gear temporarily rotates the rotating wheel so that the first and second gears can mesh. The guide has a first cam that moves the opener such that the first protrusion does not interfere with the latch when the tray is loaded/unloaded.

A disk player has a tray capable of moving in and out of a player body. A driving unit moves the tray. A lift unit selectively engages or disengages the driving unit and raises a turntable receiving a disk loaded by the tray thereon. A spindle motor rotates the turntable. A damping unit reduces loads and impacts during movement of the lift unit.

An optical disk player with improved opening and closing of a door, transport of a tray, and an improved pivoting structure of a chassis to pivot a turntable. The optical disk player includes: a body; a tray to move in and out of the body so as to transport an optical disk; a chassis installed to pivot inside the body; an optical pickup, which is installed to be able to move back and forth in the chassis, to record/reproduce information onto/from the optical disk that is rotatably placed on the turntable; a cover installed on a front of the body, the cover including: a door holder with an aperture through which the tray moves; a door to be able to slide along the door holder so as to open and close the aperture; and a cam driving device to activate the tray, to pivot the chassis, and to open and close the door by sliding.

A disc recording/reproducing apparatus includes a main frame, a disc cartridge including a case with an opening on a bottom thereof to expose a disc-type recording medium and a window on a sidewall thereof, a shutter mounted in the case to expose and cover the opening, a rotary wheel operating in association with the shutter, and a latch unit formed at one side of the case to control rotation of the rotary wheel, a tray mounting the disc cartridge and moving with respect to the main frame, a shutter opening/closing unit connected to one side of the main frame, a rack member of a cantilever type contacting with the rotary wheel, and first and second connection ribs connected to a static part of the shutter opening/closing unit, and a cam guiding the rack member distanced in relation to or from the latch unit, during shutter opening/closing operations.

Disc recording/reproducing apparatus

A disk drive including a tray on which a disk cartridge is mounted and is loaded into and unloaded from a main body; a guide formed on the tray; and an opening and closing member installed to be elastically connected to the guide. The opening and closing member has a second gear that rotates a rotating wheel by meshing with a first gear; and a first protrusion formed on one end of a second gear and to temporarily rotate the rotating wheel so that the first and second gears can mesh. The guide pushes the first protrusion during loading/unloading of the tray so that the first protrusion and the latch do not come in contact with each other.

A clothes washing machine includes a water tub, a spin basket, and a clothes agitator. A vertical dehydrating shaft is fixed to the spin basket, and a laundering shaft extends coaxially within the dehydrating shaft. Upper and lower ends of the laundering shaft are connected to the agitator and a motor respectively, whereby rotation of the motor is always transmitted to the agitator. In order to selectively connect the dehydrating shaft to the laundering shaft (e.g., during a spin-drying operation), a connecting gear is mounted on the dehydrating shaft for rotation therewith and for vertical movement relative thereto. A power-driven actuator is provided for selectively moving the connecting gear up or down. When the connecting gear moves down, lower teeth thereon become operably connected to the motor so that the dehydrating shaft and laundering shaft rotate together. During a washing or rinsing operation, the connecting gear is moved up, whereby upper teeth thereon become connected to a fixed element, whereby the dehydrating shaft is fixed against rotation.
