6.3. Gate Mechanism
1. The Conveyor Motor is reversed after documents
feed is finished and the cam of the Feed drive shaft
is rotated.
The Gate lock levers and Document stages are lifted
by the cam and the Gates are locked to stop feeding
documents.
Document stages work so that documents do not
touch Feed rollers.
2. When the Feed drive shaft is rotated 180
in the
direction feeding document, the Gate lock levers are
lowered and the Gates becomes free.
It is the possible state for the Gates to feed docu-
ments.
The Document stages start a descent at that time.
3. When the Feed drive shaft is rotated 270
in the
direction feeding document, the Document stages
are fully lowered.
The cam of Feed drive shaft is stopped rotating by
the stopper of Lower chassis and Feed drive shaft is
slipped by the coaxial Torque limiter.
The Feed drive shaft is kept driving by the function
of the torque limiter and the document feeding is
maintained.
