を特徴とする光学式情報ピツクアツプ装置。 It includes a housing that houses an optical system that irradiates a light beam obtained from a light source onto a recording surface of an information recording medium through an objective lens, receives the reflected light, and relays it to a light receiving element, and a lens drive system that positions the objective lens. The optical information pickup device is a first optical information pickup device that is movably held in the housing in only one direction substantially perpendicular to the optical path of the light incident on the light receiving element.
a support member, a second support member supporting the light receiving element and attached to the first support member so as to be movable only in the optical path of the incident light and in another direction substantially perpendicular to the one direction; 2. An optical information pickup device comprising: an elastic member that presses the support member toward the housing.
