A multi-disk player system comprising a housing, a playing mechanism provided within the housing, a magazine that is capable of accommodating a plurality of disks in an orderly manner and which is provided detachably with respect to the housing, a magazine loading detector for detecting the loading of said magazine within the housing, and a disk pickup and transport device that selects a desired disk from the magazine and transports the same to the play position. The magazine loading detector is comprised of a pair of push levers that are positioned in the deepest magazine loading area and are in engagement with the magazine, a pair of sensor switches capable of engaging with the push levers. The push levers are spaced apart from each other by the distance corresponding to the thick portion of the magazine. The system may include a disk container comprising a plurality of trays on which disks are to be placed, and the magazine for accommodating the trays. The magazine is provided with partitions that limit the vertical position of the trays. The height of the underside of each partition is set at a value equal to that of the top of the disk placed on the tray below each partition.
A disk container comprising a plurality of stacked trays on which disks are to be placed, and a magazine for accommodating said trays, at least one magazine element at a side of said magazine having partitions defined by spaced grooves sized to the thickness of said trays, and wherein said trays have peripheral portions fitted within said grooves with said tray peripheral portions overlapping the partitions with the trays fully positioned within the magazine, each tray having a manually accessible claw, and said claws being arranged in a forwardly and rearwardly offset alternate manner when received in said magazine, means for supporting said plurality of stacked trays for rotation about a common pivot axis parallel to the direction of stacking of said trays, and wherein said adjacent tray claws are at radially offset positions with respect to said common pivot axis to facilitate selective pivoting of a tray from a position internally of said disk container magazine for permitting placement of a disk on said selected tray or removal of said disk therefrom.
A disk container comprising a plurality of stacked trays on which disks are to be placed, a shallow circular recess within the center of each tray, the recess diameter being substantially equal to the diameter of the disk for receiving said disk, a magazine for accommodating said stacked trays, means carried by said magazine for mounting said trays for movement into and out of said magazine at right angles to the stacked direction of said trays, said magazine including at least one magazine element having partitions defined by spaced grooves sized to the thickness of said trays, said trays having peripheral portions fitted within the grooves and overlapping the partitions when the trays are fully positioned within said magazine, and wherein said recesses and said disks carried by said recessed are sized such that the disks have peripheral portions retentively held within said tray recesses by said partitions when said trays are fully positioned within said magazine.
A disc container comprising a plurality of trays formed substantially in a rectangle in plan configuration and a housing adapted to hold said plurality of trays in a vertically stacked manner at a given pitch and to maintain said plurality of trays for rotation about a common vertical pivot axis, wherein an L-shaped opening is formed by a first side wall, in the vicinity of said tray common vertical pivot axis of said housing, and by a contiguous second side wall intersecting the first side wall remote from the pivot axis, and wherein said plurality of trays are rotatable through said L-shaped opening between a disk retraction position and a disk exchange position.
