Abstract
A disk reproduction apparatus of the type capable of being displaced from a horizontal attitude to a vertical attitude or vice versa includes an outer casing; a support frame disposed inside the outer casing in a floating manner and loaded with a magazine in which a compact disk is mounted; a vibration proof mechanism disposed between the corresponding side surfaces of the outer casing and the support frame; and a pickup device disposed above the compact disk, and being movable and adapted to read the information recorded on the compact disk. The vibration proof mechanism includes a support, such as a rotating plate, pivotally secured to the side surface of the outer casing, and a spring having one end engaged with the pivotal rotating plate and the other end secured to the side surface, opposing to the side surface of the outer casing, of the support frame. Several vibration proof mechanisms may be disposed on both side surfaces of the outer casing and the support frame. The operation of the pickup device is controlled by a servo-controlled mechanism so as to be movable in a radial direction of the compact disk.
