(20) Setting the original at the exposure position (completion of No.2 side feed)
The same processes from (9) to (11) are carried out, and the top side of the original is set at the
exposure position. If there is an original on the tray when feed is completed, initial alignment of the
next original is started.
* From here on, operation is repeated until all of the originals on the tray are fed.
(21) Start of exit of final original to completion of exit
When the exit signal is received during exit of the final original, the DF operation in progress signal is
set. Then, the transport motor and reversal motor start to operate in the forward direction, the trans-
port belt and reversal roller rotate to start exit operation, and the original on the original glass is
transported to the exit section. At the point when the exit sensor turns ON, the number of drive pulses
up to start of exit deceleration is set. At the point when the number of pulses is counted up, decelera-
tion of the transport motor and reversal motor is started, and the original is output at low speed. At the
point when all originals in the DF have been output, the transport motor and reversal motor stop, exit
is completed, the DF operation in progress signal is reset, and feed operation is completed.
