Abstract
Abstract A tape playback head in conjunction with a continuous prerecorded magnetic tape for providing an output signal each time the tape makes a complete revolution, said signal being utilized to stop conduction in an SCR upon the first occurrence thereof and the second occurrence being allowed to pass through the SCR circuit to the base of a transistor to cut off the transistor and open a relay circuit to remove power from the tape-driving mechanism. Turning on the tape-driving apparatus, triggers the SCR to produce conduction therein and prevent passage of signals through the circuit thereof until conduction in the SCR is again stopped by the first signal. Thus, the continuous tape is allowed to make two complete revolutions and actuating the energizing switch during the second revolution resets the circuitry so that an additional revolution will be made.
