OPERATION DESCRIPTION
[1] Disc Loading
(1)Turning the loading switch ON
1)When a disc is inserted, the disc arms open to the left and
right and the claw below disc arm (L) sets the loading switch
ON.
2)The above starts the motor rotation.
(2) Loading the disc
1) When the motor starts rotation, the worm gear also starts
to turn as shown in the figure.
2) The rotation force is transmitted to the gear train.
3)When the force is transmitted to the final gear, the rollers
rotate to pull in the disc.
The disc is pulled in or out when the rollers are pushed against
the disc guide.
[2] Operation of Slider (R)
(1) Activating the trigger arm
1)When the disc is pulled in by the rollers, the disc edge pushes
the trigger arm and rotates it.
2)When the disc is an 8cm disc, it is pulled upwards by the
tapering on the disc guide.The trigger arm is rotated when
the disc pushes the claw (section A) located before the trig-
ger arm.
When the 8cm disc reaches the loading end position, the roller
areas supporting the disc decreases.To prevent the disc from
dropping in this case, the claw is provided with a projection for
supporting the disc.

OPERATION DESCRIPTION
(2)Basic construction (Initial position
of the planetary gear mechanism)
1)Even after the disc has been inserted, the
motorrotated and the gear train also rotated,
slider (R) does not start operation yet.This
is because the planetary gear mechanism
is used and the carrier gear is locked by the
slider mechanism. In this period, the plan-
etary gear is in the loose condition.
2) When the sun gear is rotating and the car-
rier gear is locked, the planetary gear is run-
ning idle.
(3)Basic construction (Construction of
the trigger slider and slider (R))
The trigger slider is assembled with slider (R)
and pushed in the direction of the arrow by
the force of a spring.
(4) Operation of slider (R)
1) Activating the trigger slider
When the trigger arm is rotated by the pres-
sure of the disc, the trigger arm pushes the
trigger slider.

2) Rotating (engaging) the planetary gear
When the trigger slider is moved, it pushes down the wall
(section A) of the carrier gear. (Initial rotation of the carrier
gear)
This causes the planetary gear, which is attached on a pin
of the carrier gear, to move according to the rotation of the
carrier gear.When the planetary gear is meshed with a gear
tooth (section B) of the traverse chassis, the planetary gear
starts rotation.
The rotation of the planetary gears causes the carrier gear
to rotate.

3) Activating slider (R)
When the carrier gear rotates, its wall (section C) pushes
and moves the trigger slider.
When the trigger slider is moved, slider (R) is pulled by the
force of spring (section D).
When the trigger slider moves along the longitudinal grooves
on slider (R) till the ends of grooves, the trigger slider itself
begins to push and move slider (R).
[3]Flow Until Disc Chucking (Playback Standby
Condition)
(1) Functions activated by slider (R)
1) Operation modes
To play back a CD, it is required to perform a flow of opera-
tions as shown below.
2)Coupling conditions
The parts used for performing the above functions are
coupled with slider (R) as shown below.
• Pulling the disc in and stopping the roller rotations after it.
• Moving the clamper downwards so that it can clamp the disc
during playback. (Disc chucking)
• Moving the rollers that are in contact with the disc.
(Lowering the roller lever)
• Float (suspend) the mechanism in order to protect it from
vehicle vibrations during disc playback.
• Moving the pickup (optical ass'y) so that it can reads the
disc signals.
These series of operations are activated by the movement of
slider (R).

OPERATION DESCRIPTION
3)Rotation of rollers during disc loading
As shown in the following figure, the
motor rotation force is transmitted
throughsun gear ➔helical gear 2 ➔ load
gear 2 to the gear that is coupled directly
with the roller shaft to rotate the roller
and pull in the disc.
(2) How to stop the roller rotation
The boss of the roller arm is engaged with
a groove on slider (R).
When slider (R) moves, the boss of the roller arm moves
along the groove of slider (R), thereby separating the
helical gear 2 coupled with it from load gear 2.
This stops transmission of the force to the rollers
so the rollers stop.

OPERATION DESCRIPTION
2)Lowering the clamper (for disc chucking)
As slider (R) moves, the plate spring sec-
tion engaged with it moves along its
groove and lowers the clamper chassis
assembly.
The following figure shows the flow of
operation.
(4) How to lower the rollers
1)Disc chucking completion position
When the disc in this position, the rollers are located
below the disc and in contact with it.
To rotate the disc for playback, it is required to sepa-
rate the rollers from the disc.
2)Lowering the rollers (Disc playback po-
sition)
As slider (R) moves, the roller lever shaft
engaged with a groove on slider (R)
moves along the groove and lowers the
rollers.
The following figure shows the flow of
operation.

OPERATION DESCRIPTION
(5) Floating position and lock position of the mechanism
The disc is loaded and ejected by rotation of the rollers that
come in close contact with the disc.
After the disc has been pulled in by the rollers, its position should
be adjusted so that it can be placed precisely on the turntable of
the traverse chassis.To make this possible, the traverse chassis
and outer chassis should be in the locked condition.
Since the outer chassis is originally locked on the main unit, if
the traverse chassis is also locked during playback, the disc
would be subjected directly to vibrations of vehicle during driv-
ing and the disc signal would be hindered, making the audio
intermittent or impossible to be played.
To prevent such a problem, the traverse chassis is suspended
from the outer case using springs or rubber dampers during
driving. This positioning protects the disc playback operations
and is referred to as the floating position.
(6) Function of slider (L)
Slider (L) ensures the mechanism lock position because
the shafts of the outer chassis are inserted into its
grooves in the same way as they are inserted into the
grooves on slider (R).
As slider (R) moves, the force moving the roller lever is
transmitted to slider (L), which also starts the sliding
movement.
When the spring is compressed gradually to a certain
point, the force changes to a reverse force, which sup-
ports the jump-up operation of the roller lever.

OPERATION DESCRIPTION
(7) Floating stroke
When the traverse chassis assembly is in
the mechanism floating position, stoppers
should be provided between the outer case
and traverse chassis assembly in order to
prevent the mechanism from being dam-
aged by vibrations and shocked of the ve-
hicle.
The distance between the traverse chas-
sis assembly and stoppers, that is, the
range in which the traverse chassis assem-
bly can move freely, is referred to as the
floating stroke.
(8) Operation of the pickup
1)Construction
The optical pickup unit is attached on the
rack gear.
The following figure shows the position-
ing of the gears.
2)Activating the pickup
After the above series of operations have completed
and the disc is put in the playback condition, the car-
rier gear rotates further and is meshed with pick gear
1.The force is then transmitted through pick gear 2 to
the rack gear, causing the optical pickup unit to move.
The operation of the optical pickup unit is controlled
by the servo circuitry.
