The driven guide plate [A] is supported by the support bracket [B]. Torsion
springs [C] hold it in the closed position. There are magnets [D] at the front
and rear. The magnets grip the drive guide plate.
Plate springs [E] are installed to the front and rear ends of the back side of
the driven guide plate. When the unit is pushed in, the roller [F] of the main
body side presses against the back plate to ensure magnetic attachment and
to prevent the driven guide plate from opening by a paper jam in the machine.
12.5 UNIT LOCK LEVER
When the vertical transport unit is set to the main body, it is locked by the
lock lever [G] applying pressure to the stopper bracket [H] of the main copier.
