GENERAL REMARKS
4
Before adjusting the mechanism of this unit, wipe the tape contacting surfaces clean as well the contacting surfaces of the
driving parts except the Drive Belt with a cotton swab a soft cloth soaked in alcohol.
Trouble may occur because of oil and grease stains.
Carefully handle the belt because grease easily attaches to it. Then, check the used rubber parts.
If the rubber has deteriorated or is scratched, replace the parts with new ones.
Silicone grease is applied to the Drive Belt to proper amount of silicone grease to the groove of the motor pulley.

If necessary, adjust the clearances as follows:
To obtain the clearance of O between the Flywheel and the
Flywheel Support, slowly turn the Flywheel Thrust
counterclockwise.
Then fully push the oil cut washer down as illustrated.
Turn the Flywheel Thrust clockwise until the clearance between
the Flywheel and Flywheel Support becomes 0.5 f 0.1 mm when
measured by the thickness gauge as illustrated.
After the adjustment, secure the Thrust with paint or glue.

PARTS LIST
PRODUCT SAFETY NOTICE
Each precaution in this manual should be followed during servicing. Components identified with the IEC symbol ~ in the parts
list and the schematic diagram designate components in which safety can be of special significance. When replacing a component
identified ~, use only the replacement parts designated, or parts with the same ratings of resistance,
wattage or voltage that are
designated in the parts list
in this manual. Leakage-current or resistance measurements must be made to determine that exposed
parts are acceptably insulated from the supply circuit before returning the product to the customer.
CAUTION: Regular type resistors and capacitors are not listed. To know those values, refer to the schematic diagram.
N.S.P
: Not available as service parts.

CIRCUIT DESCRIPTION
a. POWER SUPPLY
● When the POWER switch is turned on, all circuits are sup-
plied with voltage from the AC Adapter.
The circuits supplied with voltage are of 3 types : circuits
supplied directly with a voltage of + 9V, circuits supplied
with a constant-voltage of + 5V, and circuits supplied with
a constant-voltage of + 7V.
1. The circuits supplied directly with a voltage of + 9V
(1) Audio amplifier (ICI and IC2)
(2) Play Drive and Rewind Drive circuits
(3) Backspace circuits
(4) Erase Head
2. The circuits supplied with a constant-voltage of + 5V
(1) MPU (Microprocessor unit) IC3
(2) Cue Tone Signal Detect circuit
(3) Rotation Detection circuit
3. The circuits supplied with a constant-voltage of + 7V
%_-
(1) Motor Governor circuit

PLAYBACK CIRCUIT
When the PLAY button is pushed, pinl (PDO) of IC3 goes
to low, as does pin9 of IC3. This activates the Play Drive
Circuit composed of Q3, Q4 and the Play Solenoid (SL1 ).
A signal from the tape is played back according to the fol-
lowing process :
Record / Play Head (HD1-1 ) + Pre-amplifier (ICI pin6 +
ICI pin3) + Tone Control (VRI ) + Volume Control (VR2)
+ Power Amplifier (IC2 pin3 -+ IC2 pin5) + Earphone
Jack (J3) + Speaker (SP1 ).
When playing back (including fast forward and rewind),
the voltage will not be supplied to pin9 of the Pre /
Record Amplifier (IC1 ).
Also, the muting transistor Q4 goes off.
CUE TONE SIGNAL DETECTION CIRCUIT
This circuit operates only during fast forward and rewind.
The Cue Tone Signal recorded on the tape is played back
according to the following process :
Record / Play Head (Search Track HD1 -2) -+ Cue Tone
Detection Circuit (IC4 pin2 + IC4 pin7) + Q13 + Q14 +
Q15 + Q16 + IC3 pin27 (PC2).
During fast forward the input Cue Tone Signal goes to ap-
proximately 400 Hz.
This signal is boosted at IC4 and when over Q16 turns on
by means of Q13, Q14 and Q15. When Q16 turns on,
pin27 of IC3 (PC2) goes to low, and the signal is picked
up by the MPU (IC3) as the Cue Tone SignaL Pin9 (PEO)
of IC3 goes to high (approx. 1.2V) for approximately 2
seconds, releasing the Play Solenoid (SLI ). At the same
time, pinl 5 (PFO) of IC3 goes to
high (approx. 2V) and the
Motor (M 1 ) drops from
high speed to normal rotation.

During rewind the input Cue Tone Signal goes to approxi-
mately 650 - 2200 Hz. This signal is boosted at IC4 and
when over Q16 turns on by means of Q13, Q14 and Q15.
When Q16 turns on, pin27 of IC3 (PC2) goes to low, and
the signal is picked up by the MPU (IC3) as the Cue Tone
Signal. Pin12 (PE3) of IC3 goes to high (approx. 1.2V),
releasing the Play Solenoid (SL1 ).
ALARM SIGNAL
The Alarm Signal is a 650Hz rectangular wave emitted
from pinl 7 (PF2) of IC3. This signal passes R19, C22,
R18 and R17 and enters pin3 of the Power Amplifier IC2,
where is boosted and emitted from the speaker as an
alarm signal.
There are 3 types of alarm signals :
(1) No Cassette Alarm . . . . . . . . sounds continuously
(2) ASOAlarm . . . . . . . . . . . . . . . . . . . approx.4 sec.
(3) Cue Tone Signal Detection Alarm . . approx. 2 sec.
BACKSPACE CONTROL CIRCUIT
When pin9 (PEO) of IC3 goes to low, the Play Solenoid
(SL1 ) functions. At the same time, Q1Oturns on, as does
Q9. When Q9 turns on, voltage corresponding to the po-
sition of the Backspace Control (VR3) is supplied to C33.
When the Foot Control Play Button is released, pin9
(PEO) of IC3 goes to high (approx. 1.2V) and the Play So-
lenoid (SL1 ) is released. At the same time, pinl 1 (PE2)
of IC3 goes to low and Q6 turns on. As a result, Q5 turns
on as long as the voltage at C33 is discharged, during
which time the Rewind Solenoid (SL2) operates.
REMOTE CONTROL CIRCUIT
By pressing the Foot Control switch, the input voltage at
pin8 of IC5 and the voltages at pinsl, 2, 3, 4 and 6 of IC5
become as shown in the following chart.
Function Pin 8 Pin 6

● MPU (IC3) picks up the output from IC5 and the voltages
at pinsl, 2, 3, 4 and 6 and performs the appropriate op-
eration (i. e., Play, Backspace, and Playback).
