Figure 1 shows what the inside of the unit
looks like
when a
disc is in play. Pressing
DISC SKIP button at this point
causes the spindle motor
to stop (disc rotation stops) and the shaft
of the sled motor to turn counterclockwise. This
causes the pickup to move in direction D.
when the position where the limit switch (SW1 )
turns on is reached, and the
sled motor stops. Simultaneously, the spindle of another motor (39) starts to turn counterclockwise, causing the gear
(31 ) to move in direction F. This causes another gear(31 ) to engage yet another gear (27), making
the second gear (27)
rotate counterclockwise. The cam portion (@) of another gear (27) is linked to the boss (@) of the lever (44), so the ro-
tation of the above mentioned gear (27) causes the lever (44) to move in direction J. The slide (45) linked to the boss
(@) moves in direction L (the switch (SW2) turns off), and the bosses (@ and @) of the sub-chassis (21) disengage the
parts ( @ and @) of the slide (45) that they had been linked to. This
frees the sub-chassis (21) so that it can move
downward

AS
shown in Figure 2, one of the gears (28) is equipped with a cam. One boss (@) of the sub-chassis (21) en9a9es it
while the second boss ( @) provide; "rotating support for the p'anel fdp (See 82 "in '"CD Turntable Exploded V!ew).
Therefore, when the gear (28) rotates, the sub-chassis (21 )
moves in direction G (downward)
as shown .
Figure 1 shows how the assembly
looks when the gear (28) has turned, causing the sub-chassis (21) to move down-
ward and the slide (45) to move in direction L.
At the same time, Figure 1 shows the switch (SW3) turns on, causing the shaft of the motor (39) to switch from coun-
terclockwise to clockwise rotation. This causes the gear (31) to turn in direction E, engaging another gear (37). The
second gear (37) turns clockwise. As shown in Figure 3, this gear (37) engages the inner gear ( @) of the turntable
(70), so the turntable (70) turns in a clockwise direction.
