CD CHANGER MECHANISM OPERATION DESCRIPTION

●

●

●

a.

●

(1

The unit is capable of loading up to six 12 cm CDs at once and playing them in sequence.

Immediately before power is turned on (off status), it is in the home position..4

Disc case : Disc 1 (top level)

Turntable : Chucking

Loading plate: Holding disc

When the unit is powered on with the CD function selected, chucking takes place on the CD that was programmed when

the unit was last operated and the unit enters the standby mode.

UP/DOWN OPERATION OF THE CD MECHANISM AND DISC CASE

Normally, the UP/DOWN MOTOR (41 4) of the disc case and CD mechanism turns the up/down cam gear (391) of the

CD mechanism in a clockwise direction, causing the up/down switch (393) to move to the “up on” position.

This puts the turntable into chucking status.

When the OPEN/CLOSE button is pressed, the cam gear (391) turns counterclockwise, putting the turntable into the

down position. (CD mechanism: down.)

(2) When the plunger (395) operates, it turns the worm gear (3661. using the gear (408) as a junction.

This causes the disc case to move up or down.

r (3) The rear of the disc case is equipped with slits (the protrusions to the right of 363) and switches, which cause a disc

case stop signal to be generated.

The loading motor (377) runs, and the loading plate (434) starts movtig toward the “OPEN” position,d..

performing the following operations.

Using hooks a and b on the loading plate (434), the CD is extractecf and moved from the disc case (363).

When it is over the turntable, hooks a and b separate from the CD and retract into the loading plate.

The CD is now “FREE” on top of the loading table.

Next, the loading plate moves further and, by pressing on the Ioadimg table (431), moves the loading table lock

lever (430) .

● The unit is capable of toading LIP [o six 12 cm CDs al once and playing [hem in sequence. d

● Immediately before power is Iurned on (off status), it is in the home position.

Disc case : Disc 1 (top level)

Turntable : Chucking

Loading plate: Holding disc

. When the unit is powered on with the CD function selected, chucking takes place on the CD that was programmed when

the unit was last operated and the unit enters the standby mode.

a. UP/DOWN OPERATION OF THE CD MECHANISM AND DISC CASE

● Normally, the UP/DOWN MOTOR (414) of the disc case and CD mechanism turns the up/down cam gear (391) of the

CD mechanism in a clockwise direction, causing the up/down switch (393) to move to the “up on” position.

This puts the turntable into chucking status.

(1)

(2)

(3)

UPI

When the OPEfWCLOSE button is pressed, the cam gear (391) turns counterclockwise, putting the turntable into the

down position. (CD mechanism: down.)

When the plunger (395) operates, it turns the worm gear (366), using the gear (408) as a junction.

This causes the disc case to move up or down.

The rear of the disc case is equipped with slits (the protrusions to the right of 363) and switches, which cause a disc

case stop signal to be generated.

(3)

Using hooks a and b on the loading plate (434), the CD is extracted and moved from the disc case (363).

When it is over the turntable, hooks a and b separate from the CD and retract into the loading plate.

The CD is now “FREE” on top of the loading table.

Next, the loading plate moves further and, by pressing on the loading table (431), moves the loading table lock

lever (430)

This causes it to link with the loading table and advance toward the “OPEN” position.

c. LOADING TA3LE MOVEMENT + ‘*OPEN”

. As it moves, the loading table performs the following operations.

(1) It removes the binder from the centering hold lever (322).

(2) It moves the cover plates (425, 427) so that the disc stopper (424) rises up and stabilizes the disc selting.

(3) It sets the OPEN/CLOSE switch (399) to the “OPEN ON” position.

d. LOADING TABLE MOVEMENT + “CLOSE’”

● After putting the disc in place and pushing the loading table (431) with your hand, the OPEN/CLOSE switch

moves to the “OFF” position, the loading motor reverses, and the loading table begins to move, performing Ihe

following operations.

(1) It lowers the disc stopper (424).

(2) When the disc sensors (345, 450) are triggered, the turntable starts up after operation (3), and the TOC is read.

(3) The loading table guide (355) disengages the loading table lock lever (430).

This undoes the link between the loading table and loading plate.

e. LOADING PLATE MOVEMENT + “CLOSE”

. The loading motor moves the ““FREE””loading plate toward the “CLOSE” position,

causing it to perform the following operations.

(1) It inserts a CD into the disc case and moves the loading completed switch (314) to the “OFF” posiiion.

(2) Hooks a and bon the loading plate clamp the CD.
