PURPOSE:To select selectively many pieces of music in order and to play them automatically without any break by using a disk exchanger and interchanging automatically specific disks between a file and an unloaded player. CONSTITUTION:The disk file 2 contains numbers of disks 1 in parallel and three disk players 3 are provided facing it; and the disk exchanger 7 which has a local controller is arranged between a guide shaft 10 and a feed screw 11 between them. A specific disk 1 in the file 2 is selected under the loading command of a computer and passed to an unloaded player to be played, and then returned to its original position under the unloading command. Thus, many pieces of music are selected successively and played automatically, one after another, without any break. |
