PURPOSE:To increase a disk exchanging speed and to ensure an assured operation of an automatic disk changing device by controlling a pocket member which is loaded into a disk by a pocket control mechanism so that it is freely loaded to and unloaded from the positions where the disk is loaded, reproduced and unloaded in a rotary system. CONSTITUTION:A prescribed one of many disks 101 stored in a tray 100 is automatically selected and loaded to a disk pocket member 511 set in response to a disk reproduction mechanism part 580. A disk pocket control mechanism 550 controls a disk pocket mechanism part 500 so that the part 500 is freely loaded to and unloaded from positions where the disk 101 is loaded, reproduced and unloaded respectively in a rotary system. A clamper part is controlled in a loadable/unloadable way with revolutions to the member 511 in response to the actuation of the mechanism 550 and clamps reproducibly the disk at the fitting part of a turnable with the magnetic force of the clamper part. In such a way, the exchanging speed is improved for disks 101 and the actuation of an automatic disk changing device with simple constitution. |
