Abstract: When a roller holder attached to a floating chassis of the disk player rotates to raise a carrier roller from a disk non-carrying position to a disk carrying position, a convex portion of the roller holder is engaged with concave portions of the main chassis from above so as to fix the floating chassis to the main chassis in the back and forth directions as well as the right and left directions. The roller holder further rotates about a fulcrum to raise the floating chassis. As a result, the floating chassis is made to abut against another part of the main chassis from below to fix the floating chassis to the main chassis in the vertical direction.

Abstract: It is an object of the present invention to simplify a structure for alternatively transmitting power to a pickup moving mechanism and a disk loading mechanism by a common motor. A worm gear is attached to the rotary shaft of a motor, a worm wheel meshing this worm gear is supported on a mobile plate 8 that is movable along the rotary shaft of the motor, and first and second gears which are positioned in right and left of the worm wheel to be alternatively capable to engage with the worm wheel are arranged. The pickup moving mechanism is operated by the mesh of the first gear and the worm wheel, and the disk loading mechanism is operated by the mesh of the second gear and the worm wheel.
