Abstract: An automatic disc changer has a casing for the automatic disc changer, and a plurality of disc holders arranged in the casing. The disc holder stores a plurality of discs in vertical position so that each disc can be removed from the disc holder. A plurality of reproducing devices are provided in the casing to be moved along the disc holder. The reproducing device has an opening at a side confronting the disc holder. A loading arm is provided for loading the disc passing through the opening. A wire is connected to opposite sides of the casing along the disc holders so as to prevent the disc stored in the disc holder from removing. A plurality of rollers are disposed in the reproducing device around the opening. The wire is engaged with the rollers so as not to obstruct the opening and to allow each reproducing device to be independently moved from the other reproducing device.

Abstract: An automatic disc changer has a casing for the automatic disc changer, and a plurality of disc holders arranged in the casing. The disc holder stores a plurality of disks in vertical positions. A reproducing device is provided in the casing to be moved along the disc holder. A movable frame is provided on the disc holder to be shifted by a pitch of the space in a direction of the arrangement of the disc holders. A plurality of guide projections are provided on the movable frame, which are disposed adjacent to ends of the holding plates. The guide projections are arranged by a pitch which is twice as much as the pitch of the space. Each guide projection has a triangular section, the bottom of which is approximately equal to a width of the space, so as to close a corresponding space.
