Abstract
An information reading apparatus generally comprises a body for accommodating optical elements such as a semiconductor laser, a photodiode and a prism, an objective lens disposed on a base of the body for reading information recorded in a recording medium, and an actuator means for positioning the objective lens with respect to a compact disk and actuating the objective lens in a direction along an optical axis thereof. In assembling the information reading apparatus, a base of the actuator means is mounted on the body, and an objective lens suspension body including an objective lens holder and a suspension base member connected thereto through a pair of bridge members is prepared by an injection molding. The bridge members are removed after the objective lens suspension body is mounted on the base of the actuator means.
