Abstract
Apparatus for sequential cyclic operation of a plurality of magnetic tape playing devices. A single side of each tape in each device is played one after the other until all the devices have been operated. Then the other side of the tape is sequentially played. The operation of the device is controlled by logic circuitry responsive to an end-of-tape sensor to operate the next device, switch the tape drive mechanism of the device just operated to play the other side of the tape when activated, and finally to switch off the previously played device. A trouble indicator responsive to the failure of the drive mechanism to be switched from one way of operation to the next is also disclosed.
