Abstract
A disc cleaning mechanism or device has a rotary brush having a rotary shaft on which a plurality of brushes are mounted and, between adjacent brushes of which a plurality of discs is inserted, and a disc revolution stopper for preventing the discs inserted between the brushes from revolving about the rotary shaft by rotation of the rotary brush and allowing the discs to rotate. The disc cleaning mechanism includes a core roller having an uneven inner peripheral portion of the brush as a core of the brush and an uneven outer peripheral portion and a rotary shaft on which a plurality of the core rollers are mounted. The brush and the core rollers constitute a spline joint.
Claims14
A disc cleaning mechanism for cleaning a plurality of discs by contacting a plurality (n) of rotating brushes with surfaces of said plurality of discs, and rotating the rotating brushes, comprising:
- a rotary brush assembly having a rotary shaft and said plurality (n) of rotating brushes mounted on said rotary shaft at equal intervals such that said discs are inserted to positions between adjacent ones of said rotating brushes;
- and
- a disc revolution stopper that prevents revolution of said discs inserted to said positions about said rotary shaft with rotation of said rotary brush assembly by engagement of said disc revolution stopper with outer peripheries of said discs and that allows rotation of said discs by disengagement of said disc revolution stopper,
- wherein each of said rotating brushes is selected from the group consisting of a disc shaped brush, a circular shaped brush and a cylindrical shaped brush.
