摘要： A cleaning device (1) for cleaning a video head and drum of a video recorder and/or playback unit comprises a housing (6) within which a carrier arm (28) is pivotally mounted and carries a cleaning brush (29) and is pivotal from a retracted position (28) within the housing (6) to a treating position with the cleaning brush (29) in cleaning engagement with the drum (2) under the action of a torsion spring (33). A retaining rib (48) extending inwardly from a lid (20) of the housing (6) acts on the cleaning brush (29) for retaining the carrier arm (28) and the cleaning brush (29) in the retracted position. An abutment edge (50) on the carrier arm (28) is positioned so that as the housing (6) is being lowered into a cassette receiving area (5) of the video recorder and/or playback unit, the abutment edge (50) is located behind a tape withdrawal roller (3) prior to the retaining rib (48) disengaging the cleaning brush (29). Accordingly, the carrier arm (28) and the cleaning brush (29) are retained in the retracted position by the tape withdrawal roller (3) until the tape withdrawal roller (3) commences to move outwardly of the cassette receiving area (5), thus preventing any danger of the carrier arm and cleaning brush becoming entangled with the tape withdrawal roller (3) or any other tape withdrawal rollers until the tape withdrawal rollers have moved outwardly of the cassette receiving area (5).

摘要： A cleaning device (1) for cleaning components (4, 5, 6, 7, 9, 10, 11) of a video unit comprises a cassette housing (15) having a pair of spools (24) rotatably mounted therein. A cleaning tape (30) is wound onto the spools (24) and is transferred from one spool (24) to the other on rotation thereof. The cleaning tape (30) when in a cleaning position engages the components (4, 5, 6, 7, 9, 10, 11) of the video unit. The cleaning tape (30) defines a central longitudinal central axis (46) which defines a sinusoidal waveform so that as the cleaning tape is wound from one spool (24) to the other along the magnetic tape path, the cleaning tape (30) cycles progressively over the components (4, 5, 6, 7, 9, 10, 11) for cleaning the magnetic tape path area (40) of the component and margin areas (41, 42) on opposite sides of the area (40). The cycling of the cleaning tape (30) may be achieved by mechanical means.

摘要： A cleaning device (1) for cleaning a read/write head of a floppy disc drive unit comprises a plate member (2) for insertion in the floppy disc receiving area. A cleaning member (7) formed by a backing material (17) with a plurality of upstanding tufts (21) of fibres (22) to clean the read/write head is provided in recesses (8) on front and back surfaces (9) and (10) of the plate member (2). Cleaning members (25) are provided in recesses (26) of the plate member (2) to clean guide rails in the floppy disc receiving area. A rotatable disc (6) is rotatable in a recess (31) defined by staggered lugs (32) and (33) and slots (34) in the disc (6) and lugs (32) provide for intermittent interruption of a light beam in the floppy disc receiving area as the rotating disc (6) rotates. This causes the read/write head to traverse across the cleaning member (7) for cleaning thereof.

摘要： A cleaning device (1) for cleaning the elements in the tape path, such as the sound head and capstan, pinch roller of a cassette player recorder, the cleaning device (1) comprises a housing (2) with brush members (10, 11, 12) projecting from a front opening (7) to clean the elements. The brush members (10, 11, 12) are mounted on a support member (23) and carrier members (16). A drive means (14) drives the support member (23) with an oscillating action. The carrier members (16) are driven by the support member (23) so that oscillation of the support member (23) pivots the carrier members (16) inwardly and outwardly of the opening (7) so that the brush members (11, 12) wipe the other elements. A reciprocating member (55) driven by the drive means (14) intermittently rotates the feed spindle of the cassette player recorder.

摘要： PCT No. PCT/IE96/00012 Sec. 371 Date Sep. 15, 1997 Sec. 102(e) Date Sep. 15, 1997 PCT Filed Mar. 14, 1996 PCT Pub. No. WO96/28817 PCT Pub. Date Sep. 19, 1996A cleaning device (1) for cleaning a lens (2) of a laser head (3) of a compact disc player comprises a carrier disc (5) which is substantially similar to a standard compact disc. Cleaning brushes (14) and (15) are located on the carrier disc (5) on a face (6) thereof which, in use, faces the laser head (3) for cleaning the lens (2) as the carrier disc (5) rotates in the compact disc receiving location of the compact disc player. A non-reflective band (25) is printed on and extends around the outer periphery (12) of the carrier disc (5) for returning the laser head (3) from the outer periphery (12) of the carrier disc (5) to an inner periphery (11), so that as the laser head (3) cycles between the inner and outer peripheries (11) and (12) across the brushes (14) and (15), the brushes (14) and (15) engage the lens (2) in two different relative directions for cleaning thereof.
