<p>An information reading apparatus (1) generally comprises a body (2) for accommodating optical elements such as a semiconcuctor laser, a photodiode (PD) and a prism (10), an objective lens (5) disposed on a base of the body (2) for reading information recorded in a recording medium, and an actuator means (A) for positioning the objective lens (5) with respect to a compact disk and actuating the objective lens (5) in a direction along an optical axis thereof. In assembling the information reading apparatus, a base of the actuator means (A) is mounted on the body, and an objective lens suspension body (S) including an objective lens holder (4) and a suspension base member (6) connected thereto through a pair of bridge members (100) is prepared by an injection molding. The bridge members (100) are removed after the objective lens suspension body (S) is mounted on the base of the actuator means.</p> |
