Abstract
A multi-disc storage player in which a plurality of discs can be stored and selected in the desired order for continuous programmable playing. In particular, the player includes a positioning device for relatively positioning a disc storage portion, which is capable of systematically storing a plurality of discs, and a disc playing device in the direction of arrangement of the discs; and a disc moving device for making a selected disc move between the disc storage portion and the playing device. The positioning device includes a movable member for carrying a selected one of the disc storage portion and the playing device, a driving mechanism for making the movable member move according to an instruction of movement, and a controlling device for issuing said instruction of movement to the driving mechanism until a designated position corresponding to a disc designated by an instruction of playing coincides with a current position of the movable member. The controlling device issues an instruction of movement to the driving mechanism to operate in a direction reverse to a first direction upon detecting the passage of a predetermined period of time before the designated position coinc…
