PLAY
At
Playback
Mode,
if
Reverse
Button
(B)
is
depressed
or
the
Sensing
Tape
passes
the
Sensing
Pole
(S1),
the
base
of
TRO202
is
grounded.
The
operation
of
TRO202
is
turned
off
and
the
voltage
is
sent
to
the
base
of
TRO203
and
operates
it.
Reverse
Relay
RLO201
is
activated
and
reverse
is
effected.
Because
RL201
is
turned
‘‘on”,
about
a
60V
current
is
supplied
to
the
left
motor
and
about
30V
to
the
right
motor
(Refer
to
Figs.
3
and
5).
At
the
same
time,
the
charge
current
flows
to
C0205
(100/16)
and
is
supplied
to
the
base
of
TR204,
and
TR204
is
turned
“on”.
Complete
charging
of
C0205
(100/16)
takes
only
about
2.5
to
5
seconds,
supplying
110V
to
the
main
motor
(See
RLO202-e-1).
A
voltage
of
about
47
volts
is
supplied
to
the
supply
and
take-up
motors
respectively
(See
RLO202-f-2)
and
the
mute
relay
(See
RLO202
g-4,
h-3)
works
to
mute
the
playback
out-
put
signal.
After
2.5
to
5
sec.
TRO204
is
turned
“off”,
and
also
RLO202
is
turned
“off”.
At
the
same
time,
a
discharge
current
of
C0206
(100/160)
momentarily
flows
and
about
a
140V
current
is
supplied
to
the
Reverse
Plunger.
Upon
completion
of
discharge
of
C0206,
about
a
35V
current
becomes
constant,
and
a
lowered
playback
head
position
is
maintained.

PLAY
During Reverse Playback, if manual reverse Forward
Button “A” is depressed or the sensing tape passes the
sensing pole “S2” the base of TRO201 is grounded,
TRO201 is turned “off”, voltage is supplied to the base
of TRO202, TRO202 is turned “on”, and TRO203 is
turned “off”.
RL201 is “off”, a-2 is turned “off” and the flow of
voltage to the Reverse Plunger is cut, the Recording
Playback Head is raised to upper position, a voltage of
30V is supplied to the left motor, and about 60V to the
right motor (Refer to Figs. 1, 2, and 3).
TRO204 is turned on within 275 to 5 seconds, supplying
110V
to
the
main
motor
(See
RLO202
e-1).
47V
is
supplied to the Supply and Take-Up Motors respectively
