ABSTRACT:
An overlapped-sheet detection apparatus can detect whether sheets are overlapped and shift the same, if overlapped, for further processing. The overlapped-sheet detection apparatus is provided with conveying belts, forwarding and shifting rollers, motor and discriminator. Conveying belts hold and convey sheets on a conveying path. Forwarding roller is provided at the conveying path to forward sheets1in a conveying direction and forward sheets in conveying direction. Shifting roller is provided opposite to forwarding roller to shift sheets back to a direction which is the reverse of conveying direction if the sheets are overlapped. Motor supplies shifting roller with driving torque to shift sheets back to the direction reversed to conveying direction. An encoder is built in motor to detect a rotation state of shifting roller. Discriminator judges from an output of the encoder whether sheets are overlapped. When sheets are overlapped, forwarding roller makes contact with upper sheet and sends the same in conveying direction but shifting roller shifts lower sheet in a direction reversed to conveying direction.
