MECHANISM
OPERATING
PRINCIPLES
(A)
RECORD
SIZE
SEARCHER
MECHANISM
An
optical
sensor
equipped
with
this
unit
automatically
searches
the
size
of
record
and
the
existence
of
record
as
well.
The
sensor
system
consists
of
the
lamp,
photo
transistor
and
the
slits
on
turntable
platter.
One
of
the
two
slits
on
turntable
platter
has
the
crest
which
works
as
a
shutter.
When
no
record
is
placed
on
the
platter,
the
photo
transistor
receives
light
from
the
lamp
twice
a
turn
through
the
two
slits;
when
a
17cm
record
is
placed,
the
photo
transistor
receives
light
once
a
turn
through
the
slit
without
crest.
The
pulse
of
light
which
photo
transistor
gets
is
transmitted
to
the
microcomputer,
and
the
pulse
of
light
is
sensed
as
the
size
or
the
non-existence
of
record
by
the
Microcomputer
(1C003).
Then
the
microcomputer
transmits
the
command-signal
of
speed
to
the
motor:
for
30cm
record
33-1/3
rpm,
for
17
cm
record
45
rpm,
for
no
record
no
rotation.
(B)
TRACKING
ERROR
CORRECTION
MECHANISM
The
tonearm
tracking
error
is
searched
by
the
Sensor
(PC201)
on
Phono
PWB
(67-1)
and
the
shutter
plate
mounted
to
the
tonearm.
The
sensitivity
of
the
sensor
has
been
adjusted
by
(VROO1).
No
tracking
error
point
has
been
settled
by
the
cor-
rect
positioning
of
phono
PWB
with
(VROQ2).
The
tracking
error,
if
occurs,
will
be
corrected
as
follows:
When
the
tracking
error
angle
is
created,
the
intensity
of
light
which
the
sensor
gets
will
be
varied.
The
variety
of
intensity
of
light
will
be
converted
to
the
current
which
flows
the
sensor.
The
degree
of
tracking
angle
is
almost
in
direct
proportion
to
the
current
near
0
degree
with
correct
adjustment
of
position-
ing.
The
current
will
be
converted
to
the
voltage
and
will
be
then
amplified
so
that
the
signal
amplified
starts
rotating
the
Servo-
controlled
Motor
(76).
The
rotation
of
the
motor
will
be
transmitted
to
the
Worm
Gear
(31)
by
the
Belt
(34).
The
Worm
Wheel
Gear
(35)
bited
the
worm
gear
will
roll
the
wire
so
that
the
Plate
Assy
(47)
on
which
the
tonearm
stands
will
be
moved.
When
the
tonearm
is
moved
to
the
position
where
the
tracking
error
angle
is
disappeared,
the
shutter
plate
will
obstruct
the
light
to
the
sensor.
The
current
will
become
lower,
the
voltage
will
become
lower
too,
and
then
servo-controlled
motor
will
stop
rotation.
