Abstract
An apparatus for repairing the surface of the optical disc, which is used to repair a damaged area of the laser transparent surface of the optical disc. A rotary seat is rotatably disposed on the base seat. An upper cover is pivotally connected with the base seat for covering the same. A buffing roller has a buffing layer and is rotatably disposed on inner side of the upper cover and passes over the disc rest face. A driving mechanism is mounted between the rotary seat and the buffing roller. When rotating, the buffing roller buffs the laser transparent layer of the disc. At the same time, the rotary seat is driven to rotate, whereby the disc rested on the disc rest face thereof is simultaneously rotated.
Claims3
An apparatus for repairing a surface of an optical disc, which is used to repair a damaged area of a laser transparent layer of the optical disc, the apparatus comprising:
- (a) a base seat;
- (b) a rotary seat having a disc rest face for an optical disc to rest thereon, the rotary seat being rotatably disposed in the base seat and having a first rotative axis normal to the disc rest face of the rotary seat, the rotary seat being supported by the base seat to rotate about the first rotative axis;
- (c) an upper cover having one side pivotally connected to a rim of the base seat as a first pivot side, the upper cover being closeable and mated with the base seat to form a cover therefore;
- (d) a longitudinally extended buffing roller having a longitudinally extended second rotative axis and a buffing layer disposed on a surface of the buffing roller, the buffing layer being concentrically disposed about the second rotative axis, the buffing roller being rotatably disposed on an inner side of the upper cover with the second rotative axis passing over the disc rest face of the rotary seat and intersecting the first rotative axis when the upper cover is closed, whereby when the upper cover is closed to cover the base seat, the buffing layer of the buffing roller contacts with and passes over an annular laser transparent layer of a disc;
- and
- (e) a driving mechanism mounted between the rotary seat and the buffing roller for simultaneously rotating the rotary seat and the buffing roller, whereby when rotating, the buffing roller buffs the surface of the laser transparent layer of the disc and at the same time, the rotary seat is driven to rotate, thereby rotating the disc disposed on the disc rest face of the rotary seat about the first rotative axis, the driving mechanism including:
- (i) a first gear formed around a rim of the rotary seat;
- (ii) a second gear rotatably disposed on the base seat and engaged with the first gear;
- (iii) a third gear fixedly coupled to the second gear and synchronously rotatable therewith;
- (iv) a fourth gear fixedly coupled to the buffing roller and separably engageable with the third gear;
- and
- (v) an operation mechanism formed by a crank directly and fixedly connected to the buffing roller for driving the buffing roller and the rotary seat to simultaneously rotate.
