ABSTRACT:
The size and orientation of a document are detected by determining the length in the horizontal scanning direction and the length in the vertical scanning direction of the document to be read through a reader. According to the detection result, it is determined whether the image of the document needs to be rotated or not so as to satisfy a condition where a shortest dimension among the transmittable widths in the horizontal scanning direction, at which no part of the image is missing, occurs and the dimension in the vertical scanning direction is minimized. According to the determination result, the document image which has been read through the reader is registered in an image memory and the registered image data is read out to transmit it to a receiver through a telephone line.
