Title:
PRINT COIL FOR DRIVING LENS
Document Type and Number:
Japanese Patent JPH08203103
Kind Code:
A
Abstract:

PURPOSE: To obtain a high-performance, small-size and lightweight print coil for driving lens to prevent vibrations produced by the force in different directions of a focusing coil which drives lens in the axial direction and of a tracking coil which drives lens in the perpendicular direction to the optical axis.

CONSTITUTION: A focusing coil 32 and a tracking coil 34 are arranged in a same plane and a reinforcing line 35 crossing between coils is formed. By this method, the print coil can be formed into an extremely thin lightweight coil and vibrations caused by driving force in different directions for focusing and tracking can be prevented.
