Title
(EN) A CLEANING DEVICE AND CLEANING METHOD
(FR) PROCEDE ET DISPOSITIF DE NETTOYAGE
Abstract
(EN)
A 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 brusches (14 and 15), the brushes (14 and 15) engage the lens (2) in two different relative directions for cleaning thereof.
(FR)
Dispositif (1) pour le nettoyage de la lentille (2) d'une tête laser (3) dans un lecteur de disques compacts. Ce dispositif comporte un disque support (5) sensiblement identique à un disque compact normal. Des écouvillons (14, 15), disposés sur la face (6) du disque support (5) qui, lors de l'utilisation, se trouve en regard de la tête laser (3), assurent le nettoyage de la lentille (2) à mesure que le disque support (5) tourne dans le logement à disque compact du lecteur de disques compacts. Une bande non réfléchissante imprimée (25) s'étend sur la périphérie externe (12) du disque support (5) et sert à ramener la tête laser (3) de la périphérie externe (12) du disque support (5) vers sa périphérie interne (11), de sorte que lorsque la tête laser (3) se déplace de manière cyclique entre les périphéries externe (12) et interne (11), transversalement aux écouvillons (14, 15), ces écouvillons (14, 15) viennent au contact de la lentille (2) selon deux directions différentes afin de la nettoyer.
