Abstract
An apparatus for positioning a sheet-like original on the feed table of a copying machine comprises a plurality of sensors, mounted on the table, that have different states of response corresponding to the presence or absence of an original at the sensor on the table. The sensors are mounted in pairs, the sensors in each pair being arranged symmetrically with respect to the center line of the feed table that extends parallel to the direction of feed of sheet-like originals. A lateral transport mechanism causes an original, lying ready to be copied, to be displaced in a lateral direction, transverse to the feed direction. A control circuit inactivates the lateral transport mechanism when one of two conditions occurs, namely, when both sensors of each pair of sensors simultaneously have the same state or when, in any one pair of sensors, one sensor has been enabled in the response state corresponding to the presence of an original and subsequently been disabled in the non-response state corresponding to the absence of the original and the other sensor of the pair has thereafter been enabled in the response state corresponding to presence of the original.
