PROBLEM TO BE SOLVED: To comparatively easily push a multilens holding an optical member into a slide base with light pressure, to exactly locate that multilens at a prescribed position and to accurately attach an optical member such as a Wollaston prism held by a multiholder at the intended position. SOLUTION: This device is provided with a slide base 20 supported so as to get closer to or away from a magneto-optical disk, Wollaston prism 56, with which laser light emitted from a semiconductor laser and radiated through an objective lens is reflected on the magneto-optical disk and the reflected light returned from the objective lens is passed, and multiholder 55 for holding this Wollaston prism 56. The multiholder 55 is provided with a pair of fixtures 81 and 81 protruded on both sides, and a pair of these fixtures 81 and 81 are attached onto the slide base 20 while being respectively fitted to a pair of fixing grooves 86 and 86 provided on the slide base 20. |
