Ground pin
Speed output
This
pin
outputs
'L''
in 33 rpm
and
"H'' in 45 rpm.
Turntable roatation output
Turntable roatates when this pin outputs
"H'" it stops when this pin outputs "L"'.
Pause cancel signal output
Record muting signal input
Reset pin
When
this pin inputs 'L'' -+''H"', reset
function operates.
Size detect input
This pin detects that there is nor record
when 4 pulses are input, there is a 17cm
record when 2 pulses are input and there
is a 30cm
record when
no pulse is input
during
roatation
of turntable. The size
is detected
by trailing-edge
portion
of
pulse.
Solenoid (PM102) output
When
this pin outputs ''H'', PM102 goes
ON.
Solenoid (PM101) output
When
this pin outputs ''H'', PM101
goes
ON.
