5.1.1 Document Take-up Mechanism
• The Original Detection Sensor detects a document that has been properly loaded in the
Document Feeder.
• The Document Stopper establishes the leading edge position of the document loaded in
the Document Feeder. The stopper is lowered in the standby state and raised when the
document is taken up and fed in.
• The Document Stopper is raised and lowered in synchronism with the raising and lower-
ing motion of the Pick-up Roller.
• The Pick-up Roller and Take-up Roller turn to take up and feed the original properly.
• The Pick-up Roller transports the original up to the Take-up Roller.
• The Main Motor drives the Pick-up Roller and Take-up Roller through a gear train and the
Paper Take-up Clutch.
