2.6 OPERATIONS OF THE MECHANISM
The following operations are described below based on the explanation of a series of combined operations of the
elements given above.
Initial operation of the mechanism
Loading operation
Ejection operation
Play operation
2.5.1 Initial operation of the mechanism
When the power is turned on, the mechanism starts initialization. It checks all trays starting from #6 for the
presence of discs. The mechanism recognizes the tray(s) which currently has a disc.
2.5.2 Loading operation
Operation sequence from the ELEV O.K. state to the loading of a disc is carried out as described below:
1 Tray into which a disc is to be ejected is selected by moving the tray group up and down by the elevation
operation.
2 Tray separation and shutter opening actions are taken simultaneously by the cam operation.
3 When the user inserts a disc into the selected tray, the phototransistor detects the inserted disc.
4 The disc is drawn inside by rotary motions of the roller.
5 The disc drawn into the predetermined position is detected.
2.5.3 Ejection operation
Operation sequence from the ELEV O.K. state to the ejection of a disc is carried out as described below:
1 Tray from which a disc is to be inserted is selected by moving the tray group up and down by the elevation
operation. The tray from which the disc is to be ejected moves to the disc insertion slot.
2 Tray separation and shutter opening actions are taken through the cam operation. Then, the eject arm
actuates to push the disc forward. At the same time, the roller starts rotating.
3 The disc is ejected by rotary motions of the roller.
4 It is detected that the user draws out the disc from the slot.
5 The steps 1 and 2 are carried out in reverse order by the cam operation. This closes the shutter.
2.5.4 Play operation
Operation sequence from the ELEV O.K. state to the play state is carried out as described below:
1 The stage moves to the position of the tray which has the disc to be played by the ELEV operation.
2 Tray separation and CRG rotation actions are taken by the cam operation.
3 The disc is clamped.
