Claims

[Scope of utility model registration request]

A disc-shaped information recording medium is placed on the horizontally pulled-out disc storage casing, and the disc-shaped information recording medium with the disc-shaped information recording medium placed thereon is stored in the device to reproduce the disc-shaped information recording medium. A disk lifting device for a horizontal loading type disk-shaped information recording medium reproducing device includes a pair of arms that slide horizontally within the playback device, and a disk-shaped information recording medium to be reproduced that is housed therein. a storage recess that prevents movement of the disc-shaped information recording medium; a disc mounting plate located within the storage recess on which the disc-shaped information recording medium stored in the storage recess is placed; a disk storage housing composed of a spring that constantly pushes up a disk mounting plate; and a disc-shaped information recording disk stored in the storage recess when the disk storage housing is stored in the playback device. A disk mounting plate is regulated so as to descend from the position of the medium and place the disk-shaped information recording medium on the turntable, and when the disk storage case is ejected from the playback device, the disk-shaped information recording medium is placed on the turntable. A disk lifting and lowering device comprising an arm assembly that releases the regulation of the disk mounting plate so that the mounted disc-shaped information recording medium is remounted on the disk mounting plate and returned to the position. Device.
