RATING PRINCIPLE (SEE Fig. 5)
During tape movement, the tape passes over three holes
in the reel table. As the tape passes over the holes, a light
bulb (electric eye) located underneath the reel table is
activated which causes C.D.S. to produce a pulse.
TR-501 operates as long as this pulse continues, and
TR-502 is inoperative as well as RL-501 Relay. When
tape movement stops and reel revolutions are stopped,
there is no pulse and the operation of TR-501 and
TR-502 reverses. At this time, the relay is actuated and
stops the motor.
