ABSTRACT:
An electronic device includes a disk selection and drive apparatus to select and drive a plurality of disks or other recording media. Cartridges, each housing a recording medium therein, are held in holding areas in a disk container. Support rods of a drive unit are supported by elongated support holes to be movable in the vertical direction. A first drive member and a second drive member, each having inclined guide portions and releasing portions for guiding the support rods, are provided. A rotary member has cams to drive the first and second drive members, respectively. The cams are grooves with arched portions. When a protrusion of the first or second drive members is confined and moved by the cams, the drive unit is positioned opposite a selected one of any of the holding areas. When the first drive member is moved through a predetermined distance in the horizontal direction, the drive unit is moved vertically to access some of the holding areas. While the second drive member is moved through a predetermined horizontal distance, after the movement of the first drive member, the drive unit is moved to vertically to access the remaining holding areas.
