1. Opening/Closing the Deck
When the deck open switch (SW100) is pushed, the deck open solenoid (SL102) goes on to free the lock on the deck
(compartment); as a result, the deck is pushed several centimeters to the front by the work of a spring. At the same
time, the deck lifter motor (M102) starts to rotate to move down the lifter inside the deck.
When the deck (compartment) is pushed into the host machine, the deck open sensor (PS109) detects the light-
blocking plate, permitting the lifter to move up as far as the pickup position.
When the deck lifter motor rotates to open/close the deck, the deck open indicator (LED100) on the open switch PCB
goes on or flashes.
