PROBLEM TO BE SOLVED: To positively fix an optical pick-up device and at the same time prevent a beam splitter plate from falling and being fluctuated even if a slide base generates creep by pinching the slide base and the beam splitter plate with a clipping member consisting of an elastic plate material. SOLUTION: A beam splitter plate 41 consists of a glass member of a thin parallel flat plate, passes outward light from a semiconductor laser 22 as it is, and changes inward light being reflected by a magnetooptical disk by 90 degrees. A clipping member 52 consists of a square thin leaf spring material with elasticity as in a stainless steel plate and is bent at two points in the longer direction of the square and hence is formed in U shape. In manufacturing, the beam splitter plate 41 is slid along a fixed wall 53 being provided at a slide base 20 and is arranged at the specified position of the slide base 20, and the base part of the beam splitter plate 41 and the fixed wall 53 are overlapped, are pinched, and fixed at the U-shaped opening of the clipping member 52. |
