１． Paper Feeding mechanism
Paper Feeding mechanismdrives ro ers by the be t of the Stepping motor
(T1,Main,Eject,Brake) and sensors (PC20,21,31,41,42,43) are insta ed to contro the eve of
sheets.
２． Hopper Mechanism
Hopper has a swing mechanism by the hopper motor. Its stroke is 55mm. Detection of vertica
position is contro ed by the sensor （F/L､L/L）.
３． Stacker Mechanism
Stacker Mechanism is a free fa type. Two stackers are equipped in the device and sheets are
ejected to two trays separate y by switching gate. Ejecting speed is contro ed by the stepping
motor so that the ejected papers are a igned.
４． Scanning Mechanism
Scanning Mechanism consists of the CCD which has the CCD Sensor, Mirror, and F uorescent
Lamp) and two sets are equipped, one for front and the other for back side.（28 type has one
mechanism for the front side.）
５． Sheet Separator
To feed a sing e paper for scanning from stack in the Hopper, it consists of Pick Ro er,
Separator Ro er, and Reverse Ro er.
６． Imprint Mechanism
Dot impact printer type is insta ed for the Imprinting mechanism.
７． Mu tip e Feed Detection Mechanism
８． Two mechanisms for the dua feed detection are insta ed in the device, U tra Sonic Sensor type
and transmitted ight type (PC22 Sensor).
