Patent ID: 8488421

Claim:
A lens cleaner which cleans an objective lens of an optical disc device, the optical disc device comprising: a spindle motor which rotates a turntable attached an optical disc; and an optical head which emits light from the objective lens to the optical disc to perform recording or reproduction of information, the optical head comprising: an elastic member which elastically holds the objective lens at a recording or reproducing position; and a lens protector which avoids contact between the optical disc and the objective lens, the lens protector being shiftable together with the objective lens and protruding toward the optical disc in close proximity to the objective lens and on an upstream side in a rotation direction of the turntable relative to the objective lens, wherein the lens cleaner has first and second lens cleaning portions, the first lens cleaning portion is provided so as to be brought into contact with the lens protector when the lens cleaner is attached onto the turntable and rotated, and to cause the objective lens to be away from the recording or reproducing position against an elastic force of the elastic member, and the second lens cleaning portion is provided on the upstream side in the rotation direction relative to the first lens cleaning portion, the second lens cleaning portion being provided so as to pass above the lens protector while the objective lens is away from the recording or reproducing position by the first lens cleaning portion, and to be brought into contact with the objective lens when the objective lens returns to the recording or reproducing position by the elastic force of the elastic member.
