Abstract
A power-driven disc storage case comprising an outer casing, a chassis, a rolling top, a plurality of disc brackets, two button switches, a micro high-speed D.C. motor, a transmission with safety protect mechanism, a main switch, and two lamps. Two discs are vertically provided on each of the disc brackets. A rolling top is opened and then the lamps installed inside are turned on so as to illuminate the disc at the front opening. The user can select a disc, press down the button switches (left or right) if it is not the target disc to be chosen by the user. The motor then drives the chain of the brackets to move the discs either left or right. The user does not release the push-button switch until a disc needed has moved to the front opening and takes out the disc.
