3. DISASSEMBLING THE MAIN PARTS
OF THE MECHANISM
POINTS TO NOTE
® When
fitting the parts of the mechanism,
refer to the
"Assembly
Notes", and proceed
in the reverse
of dis-
assembly order.
© Dis-assembly and assembly should be carried out in
EJECT
mode
unless
a movement
mode
is explicitly
specified. EJECT mode is the state in which the cassette
tape has been ejected.
¢ Clamps are used to prevent parts coming loose. When
removing aclamp, be careful not to force it, as this can
result in damage.
3-1. HOW TO MAKE THE MECHANISM
MOVE
In order to check
a movement such as front loading, front
unloading, tape loading, tape unloading, raising/lowering
and pressing the pinch roller, you will need to operate the
loading
motor. There are two methods
of operating the
loading motor, and these are explained in sections 3-1-1
and 3-1-2. The above movements can also be performed
without
operating the loading motor,
by following the
method
explained in section 3-1-3.
3-1-1. HOW TO OPERATE THE LOADING MOTOR
USING A DC VOLTAGE SUPPLY
(See Fig.3-1-1)
1)
Remove the power plug from the socket.
2)
Remove
the top cover, front cabinet assembly and
bottom cover.
3)
Supply a DC voltage in the range 5V between
the
MOTOR (+) wire and the MOTOR (-) wire on the CP-1
PWB assembly. To make the loading motor rotate in
the PLAY
or FF/REW
direction, the positive terminal
should be-connected to the MOTOR
(+) wire, and the
negative terminal to the MOTOR
(-) wire. To make it
rotate in the EJECT
direction, connect the positive
terminal
to the MOTOR
(-) wire,
and
the
negative
terminal to the MOTOR (+) wire.
When rotating the loading motor in the EJECT direction
with
a tape slacken, stop the rotation of the loading
motor before beginning front unloading.
Rotate the capstan
motor with your hand, wind the
slacked part of the tape, and rotate the loading motor
in the EJECT direction again.
NOTE 1: When carrying out front loading, release the lock
by pressing down the tray lock lever® and the lid opener
lever @) of the cassette mechanism
assembly (shown in
Fig.3-2-2) in the direction of the arrow.
NOTE 2: When the loading motor stops rotating, following
the Completion
of an operation
such as tape loading or
front unloading, switch off the DC voltage supply.

3-1-2. OPERATING THE LOADING MOTOR
BY THE
MANUAL
METHOD
(See Fig.3-1-2)
Refer to section 3-2 and install the mechanism
unit.
Using your finger, turn the loading motor Jocated at
the rear of the mechanism
unit. For EJECT, turn the
loading
motor
in the direction
of the arrow
on
the
loading
motor.
For PLAY
or FF/REW,
turn
it in the
opposite direction.
When rotating the loading motorinthe EJECT direction
with a tape slacken, stop the rotation of the loading
motor before beginning front unloading.
Rotate the capstan
motor with your hand, wind
the
slacked part of the tape, and rotate the loading motor
in the EJECT direction again.
When
carrying out front loading,
release the lock
by pressing
down
the tray lock lever
and the lid
opener lever ©) of the cassette mechanism
assembly
(shown in Fig.3-2-2).

3-1-3. MAKING THE MECHANISM
MOVE USING
THE MANUAL METHOD
Refer to section 3-2 and remove the mechanism unit.
Refer to section 3-15 and remove the gear wheel 2.
If youturn the main cam anticlockwise, the mechanism
will switch to a mode such as PLAY or FF/REW.
To
switch from FF/REW
mode to EJECT
mode, turn the
main cam clockwise.
