Title: Driving device for optical system
Inventor: NAKAHARA TAKASHI
IPC: G11B7/09
Filed: 1987-02-03
Abstract: PURPOSE:To improve the focusing performance, and to record and reproduce a stable optical signal by providing a means for preventing the electrostatic charge of a static electricity on a lens barrel for holding an optical system. CONSTITUTION:A lens L for adjusting exactly a focus of a light beam to a pit on an information recording carrier is fixed to the lower end part of a lens barrel 1 having a cylinder shape. This device is provided with an earth E1 in which one end is connected to said lens barrel 1 and the other end is connected to a device earth. In such a constitution, when a recording carrier C to which an electrostatic charge is charged electrostatically has been inserted into a prescribed position against an actuator, since the lens barrel 1 is connected to an earth, the electrostatic charge induced to the lens barrel 1 flows to an earth, therefore, the lens barrel 1 is not charged electrostatically, and an electrostatic attraction force to the inside surface of a guide hole 2a is not generated either. Accordingly, sliding in the focus direction of the lens barrel 1 can be executed without any obstruction. In such a way, an auto focusing servo becomes stable, therefore, a servo-circuit of this servo can be simplified.
