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 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.摘要翻译： 一种清洁装置（1），用于清洁带路径中的元件，例如声音头和绞盘，盒式录音机的夹送辊，清洁装置（1）包括具有刷构件（10,11）的壳体 ，12）从前开口（7）突出以清洁元件。 刷构件（10,11,12）安装在支撑构件（23）和托架构件（16）上。 驱动装置（14）以振荡动作驱动支撑构件（23）。 载体构件（16）由支撑构件（23）驱动，使得支撑构件（23）的振动使载体构件（16）向内和向外枢转，使得刷构件（11,12） ）擦拭其他元素。 由驱动装置（14）驱动的往复运动构件（55）间歇地旋转盒式录放机的进给心轴。

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 a lens of an optical head of an optical disc drive unit comprises a carrier disc (2) similar to a compact disc or a CD-ROM disc for inserting in a disc receiving area of the optical disc drive unit. A brush type element (7) comprising a woven base member (9) with tufted filaments (10) extending from the base member (9) is located in a receiving recess (5) in the carrier disc (2). The filaments (10) are flexible relative to the base member (9), and the tufting of the filaments in the base member (9) permits limited hinging of the filaments (10) relative to the base member (9). The depth of the base member (9) is less than the depth of the receiving recess (5), and the area of the base member (9) relative to the area of the receiving recess (5) is such as not to inhibit the flexibility of the filaments (10) relative to the base member (9). The carrier disc (2) is rotated in the disc receiving area of the optical disc drive unit, so that the brush type element (7) wipes the lens of the optical head for cleaning thereof.

摘要： A protective device (1) for protecting an optical head (2) of a disc drive unit against dirt and dust and shock when the disc drive unit is not in use comprises a carrier disc (5) similar to a music CD disc for engaging in the disc receiving area of the disc drive unit. A brush member (6) located on the carrier disc (5) at a position corresponding to the inner data track (10) of a music CD disc is provided for engaging a lens (3) and a peripheral portion (7) of a lens carrier (4) of the head (2) when the head (2) is in the inactive position for protecting the lens (3) and the peripheral portion (7) against dirt and dust. Fibres (15) of the brush member (6) are of sufficient length to engage and embrace the lens (3) and the peripheral portion (7) of the lens carrier (4) when the head (2) is in the inactive position. The fibres (15) are of sufficient resilience for also protecting the head (2) against shock. The brush member (6) also cleans the lens (3) as the brush member (6) passes by the lens (3) on insertion and ejection of the carrier disc (5) in and from the disc receiving area. Further cleaning can be achieved by activating the disc drive unit for causing the head (2) to go through a number of data focusing cycles for urging the lens (3) into and out of the brush member (6).
