Abstract
A power-driven apparatus for assisting in loading and unloading a disc into a player or recording apparatus comprising a housing for receiving and supporting the disc, a power-operated movable roller driven by a motor to rotate the disc and a movable detector for energizing the motor for guiding the disc into and out of the housing of the player. The edge of the disc is engaged by the roller which positively rolls the disc along an entrance surface, the roller and entrance surface being covered by a material having a high coefficient of friction so that the roller positively rolls the disc both into and out of the apparatus to assist in the loading and unloading.
