摘要：(57)< Abstract > < Objective > Four Kaschin in 3 axial actuatorStabilizing each servo of gu, tracking and jitter, it does. < Constitution > The glass lens holder 1 which installs object lens 134, is supported with holder support component 19. Holder support componentAs for 19, glass lens holder adapter unit 19of a center and marginal sideFixed
way adapter unit 19b and 4 these flexibility arms 19cIt consists of. As for glass lens holder 14, holder support component 19With deformation focusing direction (arrow Fo direction), toratsukingu direction (arrow Tr direction) and jitter direction (arrow ZiDirection) it is displacement possible. As for focusing coil 16It is quadrangular tubed. This focusing coil 16 4It makes the tracking coil on 2 aspects where among of the surfaces opposesCompressed coil 17 of the te is installed, on 2 aspects where other things oppose jiCompressed coil as tsutakoiru 18 is installed. ThisAnd others the magnet 12 operation the magnetic field to the coil is laid outru. The object lens type of mounting by this holder support component 19Each focusing, each operation of tracking and jitterIs stability.
