Abstract

A disc cleaner includes a disc rotation mechanism that rotates a disc (A), a cleaning member (14) for cleaning a reading surface during the rotation of the disc (A) and a press member that brings the cleaning member (14) into contact with a press member (16). The disc cleaner is provided with a movement mechanism that moves the press member (16) along the radical direction of the disc (A) during cleaning when the disc (A) rotates, and that allows the press member (16) to reach the outside of the recording region of the disc (A) when cleaning is completed.

Claims

1. A disc cleaner comprising a disc cleaner that has a disc rotation mechanism, which rotates a disc, a cleaning member for cleaning a reading surface during the rotation of the disc, and a press member that brings the cleaning member into contact with the reading surface,

wherein the cleaner includes a movement mechanism that moves the press member along the radical direction of the disc during cleaning when the disc rotates, that allows the press member to reach the outside of a recording region of the disc.

2. The disc cleaner according to claim 1, where the movement mechanism moves the press member from the internal circumference side to the external circumference side of the disc.

3. The disc cleaner according to claim 1 or 2, where the movement mechanism allows the press member to reach further outside of the external circumference of the disc when cleaning is completed.

4. The disc cleaner according to claim 1 or 2, where the disc is housed within a disc cartridge, and which has a shutter and an opening;

and that additionally has a plate-state member from a gap between the outside edge of the opening which appears in the state with the shutter opened, and the disc, through the outside of the disc cartridge; and

where the movement mechanism allows the press member to reach the upper portion of the plate-state member when cleaning is completed.

5. A disc cleaner according to claim 1 or 2, where the cleaning member is a cleaning cloth established so as to pass between the press member and the reading surface, and which additionally has a winding mechanism for winding the cleaning member during cleaning.

6. The disc cleaner according to claim 5, where the winding direction of the cleaning intersects with the movement direction of the press member.

7. The disc cleaner according to claim 5, where the winding direction of the cleaning member is opposite to the movement direction of the press member.

8. The disc cleaner according to claim 1 or 2, where the press member is formed from an elastic body.

9. The disc cleaner according to claim 8, where the press member has a pointed extremity for the purpose of extruding the cleaning member toward the reading surface.

10. The disc cleaner according to claim 1 or 2, where two sets of the cleaning member and press member are established to be cleanable from both sides of the disc.
