ELEVATING/LOWERING MECHANISM OF REPRODUCING UNIT CHASSIS OF OPTICAL DISK REPRODUCING DEVICE

PROBLEM TO BE SOLVED: To improve the spatial efficiency by making a driven member smaller and also to enable the accurate positioning of a reproducing unit chassis. SOLUTION: In the optical disk reproducing device for clamping/unclamping the disk on a tray by a turntable fixed to a rotary shaft of a disk motor in the manner of holding the disk motor on the reproducing unit chassis 4 to elevate/lower the reproducing unit chassis 4, one side of the reproducing unit chassis 4 is supported by a fixed chassis through an elastic material, and another side confronted with one side of the reproducing unit chassis 4 is supported by a turning member 29 through a clamper 5 and a spring 6, then in the turning member 29, the turning shaft 29a is arranged outside the reproducing unit chassis 4 and also a protrusion 29c is provided for positioning the descending position by abutting on the reproducing unit chassis 4 when it is descended.
