Abstract: An automatic disk changer is disclosed in which tray guides are provided on a large number of levels in a case at right and left portions thereof so that the center line of the guide on each of the levels at the right portion and that of the guide on the level at the left portion extend toward a tray transfer mechanism and meet each other in the form of a V. The tray transfer mechanism can be moved up and down between each of the guides and a disk player for playing a disk in a tray transferred by the tray transfer mechanism, be swung from a central portion to positions corresponding to the guides on each of the levels at the right and left portions, and be moved backward and forward, to and from each of the guides.

Abstract: An automatic disk changer in which a tray guide for storing a disk while it is not being played is provided in a case. A tray for containing the disk is guided by the tray guide. The tray has nearly the same size as the disk to be contained in the tray, and has a window through which a laser beam from a pickup passes and which extends to the peripheral portion of the tray. The disk changer includes a disk player which is also provided with a further tray guide for guiding the tray and is installed so that the disk is pinched and moved up by a turntable unit and a clamper and the tray is thereafter moved in the direction of movement of the pickup.
