Power Off - Sanyo GCD 2000 Service Manual

.-
AS the turntable (7o) rotates, the sensor (PStM 1) detects the slits (@ and @) in it. The first slit (@) is used tO detect the
disc number and the second slit (@) to detect the stop position. When the
senmr (PSO11 ) detects the specified disc
number*, the shaft of the motor (39) begins to turn more slowly, and the turntable Sows down.
When the next slit (@) is
detected, the rotational direction of the shaft of the motor (39) again
reverses and N begins to turn counterclockwise. As
shown
in Figure 1, this causes the gear (31} to turn in direction F (Figure 1). As shown in Figure 1, another gear (28)
then starts to turn and, in the reverse of the operation described above, the sub-chassis (21)
rises and the slide (45)
moves in direction K , eventually ending up as
shown
in Figure 5.
At this point, the switch (SW2) turns on
and the motor (39) stops. At the same time. the sub-chassis (21) is locked in the
lowered position by
the slide (45).
Note : Specified disc number ;DISC SKIP button : the next disc number.

place.
If the switch SW3 is not on :
The spindle of the motor (39) rotates counterclockwise, lowering the sub-chassis (21 ). When the switch SW3 turns
on, the rotational direction of the motor shaft changes to be clockwise. This causes the turntable (70) to rotate. When
the sensor (PSO11 ) detects the disc 1 stop position, the motor (39) switches back to counterclockwise rotation, rais-
ing the sub-chassis (21 ) and performing checking. When another switch SW2 turns on, the motor stops.

3 ) POWER OFF (MANUAL Switch Off)
Basic operations : 1. If
the motor (39) was stopped, it remains so.
2. If the motor (39) was running, then the motor stops.
