LENS-PROTRUSION TYPE OPTICAL PICKUP ACTUATOR

摘要

PURPOSE: A lens-protrusion type optical pickup actuator is provided to prevent the transmission of vibration from a head part to a tail part of a lens holder by coupling a vibration absorbing element in the central portion to which the deformation force generated in the tail part. CONSTITUTION: A lens-protrusion type optical pickup actuator includes a lens holder(112) having a protruded head part(112a) for securing an objective lens(111), and tail parts(112b) integrated with the head part and each having a rear part in the shape of opened leg, and vibration absorbing elements coupled between the head and tail parts for reducing the vibration transmitted from the tail parts to the head part of the lens holder by absorbing the strain energy in the vibration mode.
