ABSTRACT:
The invention relates to a semi-automatic aligning and feeding device (1) for copiers, for the purpose of aligning an original (25) and feeding it from a feed table (17) to an object stage (5). Sensors (L.sub.1 to L.sub.5) are provided for scanning the original in various positions. Except for one sensor (L.sub.2), the sensors are located in or on the pivotable cover (3) of the device. The original, laid by hand onto the feed table (17), is picked up by a suction bar (11) which is equipped with spring suction heads (12, 12') and is, corresponding to its particular operating state, supplied either with vacuum or with compressed air and can be moved from a starting position into an end position and back again. In the end position, the spring suction heads are supplied with compressed air so that the original is laid down in precise alignment on the object stage.
