At Playback
position, when
Reverse
button (B) is
depressed or the sensing tape passes the sensing pole
(Si), the base of TRO202 is grounded. The operation of
TRO0202 is stopped and the voltage sent to the base of
TRO203
and
operates
it. Reverse
Relay
RLO201
is
actuated and Reverse is effected.
At the same time, the discharge current of Condenser
C0205 (100M/16V) actuates TRO401 and TR104 which
assume operating position within a period of from 4 to 8
seconds.
Tension Relay (RL0401) is actuated and a higher voltage
than during reverse playback time (47 V) is supplied to
the Take-Up torque motor. At the sametime Mute Relay
(CRL1017) mutes the playback output signal.
Plunger (SRO301) operates and lowers the playback
head.
