(17) Restart of forward rotation transport to completion of forward rotation transport
After exit of the output original is completed, forward rotation transport of the original standing by
before the reversal section is restarted. The transport motor and reversal motor start to rotate in the
forward direction to rotate the transport belt and reversal roller. At the same time, the flapper solenoid
turns ON to switch the reversal flapper to the reversal side. After the exit sensor turns ON, the original
is transported for a specified number of pulses. At the point where the leading edge of the original is
nipped by the reversal roller lower passage roller by a specified amount or more, the transport motor
and the reversal motor stop.
(18) Start of reversal to flapper solenoid OFF
After forward rotation transport is completed, the transport motor starts to rotate in the reverse direc-
tion, and the reversal motor starts to rotate in the forward direction to rotate the transport belt and
reversal roller to start reversal of the original. The original passes along the reversal path and is
transported onto the original glass. At the point when the trailing edge of the original has passed the
reversal flapper, the flapper solenoid turns OFF, and the reversal flapper is switched to the exit side.
(19) Setting the original at the exposure position (completion of No.1 side feed)
The original is transported by a specified number of pulses after reversal starts. At the point where the
original arrives at the exposure position, the transport motor and reversal motor stop, and feed is com-
pleted. The original is stopped in contact with the original stopper, and the rear side of the original is set.
