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.
