Abstract

PURPOSE:To reduce the size of a device, by providing a neutral point holding mechanism in an objective holding cylinder. CONSTITUTION:An objective holding cylinder 19 is held on a supporting shaft 9 in such a way that it is displaced in a focusing and a tracking direction. The cylinder 19 is held elastically by an elastic supporting plate 10 by the intervention of a supporting pin 26, so it serves as a neutral point holding mechanism to allow retaining force to operated upon the displacement of the cylinder 19 by the driving of a linear motor and a rotating motor. The elastic supporting plate 10 is made of a polyurethane, etc., and is contained in a cut part 7, making the object device 1 compact.
