@ Disc Loading
The rotation of the gear (D) moves the slider cam (A) in Y direction and the slider cam
(B) in X direction. Then, the chassis tray and the drive unit move in Q direction along to
edges of the cams.
Motion of the bracket sensor in X, Y directions moves the position sensor volume,
thereby controlling movement distances of the chassis tray and the drive unit.
The chassis is stopped at the first disc position in the magazine. (This operation is the
same for 2nd through 12th discs except the movement distance of the chassis is
different.) Figure 10
a The loading motor rotates. (The loading motor can rotate in forward and reverse
directions.)
The rotation of the gear (H) moves the arm push-pull in Y direction through the lever
cam and takes out the tray from the magazine.
In the same way as in the step (8), the rotation of gear (H) moves the slider lock claw at
side of the chassis tray through the lever slider lock and engages it with the slit
provided on the chassis frame, thus locking the chassis tray.
10 In the same way as in the step (9), the rotation of gear (H) turns on the switch A
through the arm switch. (Confirmation of the tray pulled into the chassis tray.)
Steps 1 - 4 (step 3 for only the drive unit) are repeated again to bring the drive unit in
the disc play position and then the disc is clamped by pressing the disc to the clamper.
