Description

ABSTRACT:
An automatic paper feeding apparatus is designed to separate and feed originals by means of a separation pad and a feeding roller. A pressure sensitive conductive rubber is used for the separation pad to convert a change in thickness of an original into an electrical signal, thereby detecting a conveyed state, e.g., a multiple paper-conveying error, of the original.
