Abstract
A self-propelled record cleaner comprising a cleaning brush, a drive wheel, and a battery-operated motor unit for driving both of the cleaning brush and the drive wheel in the opposite directions with respect to each other. The self-propelled record cleaner has a bearing hole adapted to receive a turntable spindle when the record cleaner is placed on a disc record mounted on the turntable. This self-propelled record cleaner can run on the disc record around the turntable spindle while brushing or cleaning dusts off from the disc record when the battery-operated motor unit is in operation. Some of components of the record cleaners are mounted in a casing at a position where they can be supported above a non-grooved area of the disc record.
Claims5
A self-propelled record cleaner for cleaning a disc record having a center opening, a non-grooved area coaxial with the center opening, a grooved area coaxial with the center opening and positioned on one side of the non-grooved area opposite to the center opening and an outer peripheral margine, all being defined on at least one surface of the disc record, said disc record being mounted on a support having a spindle which, when the disc record is so mounted with said at least one surface thereof facing in a direction opposite to the support, projects through the center opening, said self-propelled record cleaner comprising, in combination:
- a generally elongated casing having a dust collecting chamber defined therein said casing also having a bearing hole defined therein at a position adjacent to one end thereof for engagement with the spindle when the record cleaner is in use;
- a generally cylindrical cleaning element supported in the casing so as to extend in a radial direction of the disc record when the record cleaner is mounted on the support with the disc record held between the support and the record cleaner;
- means for defining a passage for guiding dusts being removed from the disc record by the cleaning element into the dust collecting chamber;
- a drive wheel adapted to run on the disc record and rotatably carried by the casing;
- means for driving said drive wheel and said cylindrical cleaning element in opposite directions with each other;
- at least two roller elements operatively carried by the casing in spaced relation to each other and also to drive wheel to provide a three-point support system for the record cleaner in cooperation with the drive wheel;
- all of said drive wheel, said driving means and said roller elements being supported in one end portion of the casing around the bearing hole.
