PANEL MECHANISM DESCRIPTION
A. Panel Opening
1. When Open button (switch) is pressed, the motor (605)
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 pushde on the arm as-
sembly
(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 assem-
bly
(604) goes down.
(3) When this happens, the planetary gear
(603) rotates.
5. When the arm assembly goes down to the open position,
the switch (641) is trned on. When the switch (641) 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.

604
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
(642), the
motor
(605) stops after 200ms.

C. Angle Behavior
1. By the position information of the LPS (642), the panel
angle is controlled.

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).
