ABSTRACT:
A document feeder, which is swingably arranged on a copying machine, which senses the position of the document on the copying table of the machine. When the document has travelled a predetermined distance, as monitored by a plurality of Hall effect sensors arranged on the motor which operates the document feeder, the motion of the document is terminated and the copying sequence begun. A special control circuit calculates the distance that the document has moved in response to the signals received from Hall sensors arranged at half slot intervals on the motor. The motion of the document is thereby stopped when it has moved a predetermined distance.
