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 coincides with the current position, after issuance of an instruction of movement in the first direction to the driving mechanism. Thus, the state of engagement between a disc, which is not completely stored in the disc storage portion, and the movable member and parts mounted thereon is released.
