Disassembling The Main Parts Of The Mechanism; How To Make The Mechanism Move - Sanyo SRT-4040 Basic Service Technical Information

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 cas-
sette tape has been ejected.
• Clamps are used to prevent parts coming loose. When
removing a clamp, 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/lower-
ing 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. The above movements can also be performed with-
out operating the loading motor, by following the method
explained in section 3-1-2.
3-1-1.OPERATING THE LOADING MOTOR BY THE
MANUAL METHOD (See Fig.3-1-1)
1) Refer to section 3-2 and install the mechanism unit.
2) Using your finger, turn the loading motor located 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 motor in the EJECT direc-
tion 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
opener lever of the cassette mechanism assembly
(shown in Fig.3-2-2).

3-1-2. MAKING THE MECHANISM MOVE USING
THE MANUAL METHOD
1) Refer to section 3-2 and remove the mechanism unit.
2) Refer to section 3-15 and remove the wheel gear 2.
3) If you turn the main cam counterclockwise, the mecha-
nism 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.
