Abstract
PURPOSE:To improve the throughput of original reading by providing a read means reading an original picture photoelectrically for each line, a detection means detected for each read of each line and a control means controlling the read for each line. CONSTITUTION:The reader is provided with the sheet mode in which an original without a file margin is carried in the subscanning direction by an original automatic feeder (ADF) 3 while the picture is read and with the book mode in which the picture is read by placing the original with a file margin onto a platen glass 27 while in operating the ADF 3 and moving an original lighting unit 24 and a mirror 25 in the subscanning direction. Moreover, a detection means 23 detecting a peak of an output of the mode for each read of each line and a control means 21 controlling the read of each lien based on the peak value detected by the detection means are provided.
