Abstract: A universal media disc cleaning/repairing device including: a main body having a receptacle for snugly receiving a universal media disc; a driving motor mounted in the main body; a disc driving mechanism rotationally drivable by the driving motor, the disc driving mechanism having a disc driving tray upward protruding from a carrier board section of the main body for rotationally driving the universal media disc placed in the carrier board section; a cleaning/repairing tray pivotally mounted on the main body and rotationally drivable by the driving motor. The cleaning/repairing tray is adapted to contact with lower side of a read/write window of the cartridge of the universal media disc placed in the carrier board section.

Abstract: A panel wiper including a wiping member including a baseboard section and a cleaning plate connected under a bottom of the baseboard section. The cleaning plate has at least one acute wiping corner for extending into the respective corners of the panel to reciprocally wipe and clean up the panel. The panel wiper further includes a holder having a bed section and an annular wall section swelling from a circumference of the bed section. The annular wall section is formed with several receptacles adapted to a profile of the baseboard section of the wiping member. The wiping member can be seated in the receptacles and stably rested on the bed section. Multiple supporting stands are arranged under a bottom of the bed section and the bed section is formed with multiple vents.

Abstract: An apparatus for repairing the surface of the optical disc, which is used to repair a damaged area of the laser transparent surface of the optical disc. A rotary seat is rotatably disposed on the base seat. An upper cover is pivotally connected with the base seat for covering the same. A buffing roller has a buffing layer and is rotatably disposed on inner side of the upper cover and passes over the disc rest face. A driving mechanism is mounted between the rotary seat and the buffing roller. When rotating, the buffing roller buffs the laser transparent layer of the disc. At the same time, the rotary seat is driven to rotate, whereby the disc rested on the disc rest face thereof is simultaneously rotated.

Abstract: An audiofrequency signal adapter with a rotary wire locating member, including: an audio cassette-shaped housing; an adapting circuit including a coupled magnetic head and a signal compensation circuit fixedly mounted in the cassette, the signal compensation circuit having an outwardly extending signal wire for connecting with an external audio signal source; and a wire locating member pivotally disposed on a rear side of the cassette. The wire locating member is formed with multiple notches. The signal wire of the signal compensation circuit extends through one of the notches out of the cassette. After rotating open the wire locating member, the signal wire can selectively ride in one of the notches. After the wire locating member is rotated back and latched with the cassette so as to firmly define the direction in which the signal wire extends out of the cassette.

Abstract: A radially reciprocating cleaning device for compact disc, including: a lower casing in which a retaining wheel is rotatably disposed, a circumference of the retaining wheel being formed with a gear section: an upper casing one end of which is pivotally connected with the lower casing for snugly mating the upper casing with the lower casing; and a cleaning mechanism including a slide board slidably disposed on a bottom of the upper casing and connected with at least one wiping member positioned on a compact disc rested on the retaining wheel. The cleaning mechanism further includes a rotary tray rotatably mounted on the upper casing for driving a cam disc to rotate. A driving post of the cam disc is slidably fitted in a longitudinal guide slot of the slide board, whereby when the upper and lower casings are mated with each other, a driving gear projecting from bottom end of the cam disc drivingly meshes with the gear section of the retaining wheel.
