Outline
of
the
Mechanism
Control
Microcom¬
puter
The
function
of
the
microcomputer,
which
is
applied
to
the
uni-directional
transport
cam
drive
control
cassette
deck
mechanism,
will
receive
an
outside
signal
from
the
opera¬
tion
switch
(operations
such
as
PLAY,
REC,
STOP,
FF)
during
the
recognition
of
the
current
condition
or
from
the
surrounding
circuits
of
the
microcomputer
(automatic
tun¬
ing,
linear
counter,
cam
encoder,
reel
pulse,
etc.)
and
sends
the
appropriate
control
signal.
To
the
mechanism:
rotational
direction
of
the
reel
motor,
speed,
stop,
rotational
direction
of
the
cam
motor,
stop.
To
the
linear
counter:
makes
an
output
of
the
mechanism
run
mode
command
(REW,
FF,
PAUSE,
PLAY).
To
the
automatic
tuning:
REC,
P/B,
LINE
mute
signal
commands.
Makes
an
output
of
the
BIAS
ON/OFF
com¬
mand
(CUE
command).
To
the
display:
REC,
PAUSE
(REC
MUTE
during
flash).
In
addition,
the
following
points
are
taken
into
consider¬
ation.
(1)
Stable
and
accurate
cam
rotation
position
control
is
required
since
a
cam
drive
method
is
employed
to
make
the
mechanism
silent.
Accurate
rotation
position
control
is
performed
by
using
a
cam
drive
with
a
rotary
encoder
detected
digital
feedback
servo.
(2)
Since
the
leading
time
of
the
cam
drive
is
slower
when
compared
to
that
of
the
plunger
method,
problems
will
arise
when
attempting
record/playback
or
stop
at
the
designated
tape
position
from
FF
or
REW,
since
tape
overrun
occurs.
This
is
especially
important
when
controlling
the
recording
from
the
position
where
the
automatic
tuning
was
completed.
(Erasing
the
previous
music
when
making
recordings
after
the
automatic
tuning
is
completed
must
be
prevented.)
For
this,
the
tape
cuing
is
corrected
after
the
automatic
tuning
is
completed
to
control
the
tape
position
accurately.
(3)
Power
outage
measures.
When
the
power
supply
is
cut
off,
the
cam
of
the
mechanism
shifts
to
STOP.
(4)
Overload
measure
s
of
the
cam
If
the
cam
stops
an
overload
for
any
reason
and
cannot
shift
to
the
target
position
within
4
seconds,
it
is
immediately
shifted
to
STOP.
If
this
cannot
be
shift¬
ed
within
4
seconds,
the
microcomputer
will
stop
all
controls
ai'd
stop
the
motor
to
prevent
a
breakdown.
•
Auto
Tuning
(CTS)
This
tuning
system
automatically
sets
the
equalizer
and
recording
sensitivity,
both
of
which
are
important
to
maxi¬
mizing
the
performance
of
various
tapes
and
to
make
high
quality
recordings.
The
tuning
time
is
only
6
seconds;
recording
chances
are
not
missed.
When
the
cassette
is
loaded,
the
auto
tape
selector
sets
the
deck
to
the
standard
optimum
condition.
Strictly
speaking,
however,
the
record¬
ing
sensitivity
and
frequency
characteristics
of
the
tapes
vary,
depending
on
its
type.
The
auto
tuning
system
allows
the
maximum
perform¬
ance
of
the
tape
to
be
heard
and
at
the
same
time
ideally
corrects
the
frequency
characteristics
to
a
flat
and
wide
range
characteristic.
