First Claim
Patent Images
1. An optical pickup actuator comprising:
- a lens holder holding an object lens;
a coil formed in a side of the lens holder;
a magnet spaced apart from and faced by the coil;
a pickup base supporting the magnet;
a fixed frame fixed to the pickup base;
an elastic support having one end fixed to the fixed frame and the other end fixed to the lens holder; and
a heat sink member formed on the magnet.
