Abstract:
1. A disk loading device, for use with a large-diameter disk and a small diameter disc, said disk loading device comprising: a traverse including a turntable for mounting the large-diameter disk or the small-diameter disk; a large-diameter disk-mounted-area which is an area where the mounted large-diameter disk, including an outermost circumference of the large-diameter disk, exists when the large-diameter disk is mounted to the turntable; a first board parallel to the large-diameter disk-mounted area and having an opening at a portion facing the large-diameter disk-mounted area such that an upper face of a disk mounted on the turntable is exposed by the opening; a second board combined with the first board to form a housing; a first positioning lever which is movably mounted to one of the first and second boards outside, in a radial direction, an outermost circumference of the large-diameter disk-mounted-area; a first detecting lever which is movably mounted to the first positioning lever; a second positioning lever which is movably mounted to one of the first and second boards outside, in a radial direction, the outermost circumference of the large-diameter disk-mounted-area; and a second detecting lever which is movably mounted to the second positioning lever, the first and second positioning levers each comprising a disk positioning portion, and each being movable from a position in which the disk positioning portion protrudes inside the outermost circumference of the large-diameter disk-mounted-area when no disk is mounted on the turntable, and a position where the entirety of the positioning levers, including the disk positioning portions, is outside, in a radial direction, the outermost circumference of the large-diameter disk-mounted area, the first and second detecting levers each comprising a disk detecting portion, and each being movable from a position in which the disk detecting portion protrudes inside the outermost circumference of the large-diameter disk-mounted-area when no disk is mounted on the turntable, and a position where the entirety of the detecting levers, including the disk detecting portions, is outside, in a radial direction, the outermost circumference of the large-diameter disk-mounted area, wherein the first and second positioning levers position the small-diameter disk in a disk mounted position in a case of mounting the small-diameter disk to the turntable, and the first and second positioning levers are pushed by the large-diameter disk, and the entirety of all the levers including the first and second positioning levers and the first and second detecting levers move outside, in a radial direction, the outermost circumference of the large-diameter disk-mounted-area when the disk detecting portions of both of the first and second detecting levers detect the large-diameter disk in a case of mounting the large-diameter disk to the turntable.
