PANEL MECHANISM DESCRIPTION
A. Panel Opening
1. When Open button(switch) is pressed, the motor
(PM1) rotates.
2. The rotation of the motor is transmitted forward
through the rack gear (616) via the gears (620~622)
3. When the rack gear (616) moves, the panel (PA1)goes
down.
4. (1) The upper side of the panel pushed on the arm
assembly (604) by the pin (]2) and the groove of
the rail (]3).
(2) The lock on the lever (A) is let go and the arm
assembly (604) goes down.
(3) When this happens, the planetary gear (603) ro-
tates.
5. When the arm assembly goes down to the open po-
sition, the switch (PS1) is turned on.When the switch
(PS1) is turned on, the motor stops after 950ms.
B. Closing Behavior
1. The motor rotates in reverse direction.
2. The arm assembly (604) goes up.When the lever (A)
goes into the lock position of the rail (612), the arm
assembly (604) stops going up.
3. When the arm assembly (604) stops, by the rotation
of the planetary gear (603), the motor rotation pushes
the rack gear (616) backward via the gears (620~622).
4. By the close position information of the LPS (VR1),
the motor (PM1) stops after 200mS.
C. Angle Behavior
1. By the position information of the LPS (VR1), the
panel angle is controlled.

PANEL MECHANISM DESCRIPTION
D. Assembly (Close Position)
1. Align the arm assembly with the pin of the planetary
gear (603).
2. Assembly these to the sub-chassis (606) along with
the rail (612).
3. Align lever (614) hole and the hold of the chassis
(601).
4. Lead wires of LPS should be kept in place with a tape
so that they would not interfere with rack gear (616).
