PURPOSE:To carry a disk smoothly with high precision by providing a cam groove which engages part of the 1st moving member and the 2nd moving member which moves freely at right angles to a tray array direction, and moving the 1st moving member by the movement of the 2nd moving member and moving a tray projecting member. CONSTITUTION:Part of guide grooves of plates 37 and 38 of the 2nd moving member is arranged at a lower side. Three pins 20c are arranged on the right and left flanks of the chassis 20 of the 1st moving member 18 with movable chassis 19 and 20 and fitted movably in guide grooves of flanks 16b and 16c of a support member 16 to guide the chassis 20 vertically. The pins 20c project out of the chassis 20 through the guide grooves and engage the cam groove in a staircase shape which have an end part aligned with the guide groove of the chassis 20, thereby moving up and down the chassis 19 and 20 by the movement of the plates 27 and 28. One of the pins 20c is provided nearby the connection part between the guide groove 30a of a tray guide member 30 and the arcuate guide surface of the moving member 18 (chassis 19 and 20), so the member 18 is positioned in the groove 30a with high precision, so that the disk is carried smoothly with high precision.
