Abstract
An original table is provided on which an original is placed. This original on the original table is scanned by a first optical unit. A conveyance path, constituting an auto document feeder, is provided near the table, and one side of the original moving on the conveyance path is scanned by the first optical unit and the other side of the original is scanned by a second optical unit disposed near the first optical unit. The scanned output of the first optical unit is stored in a memory which can delay its content by a time corresponding to the distance between the first and second optical units. The signal stored in this memory and the scanned output of the second optical unit are sequentially outputted.
