ABSTRACT:
In an image reading apparatus used for a copying machine and a facsimile device, an image reading scanner is separated from a main device of the apparatus in order to increase the freedom of the scanning direction of the original and increase the operability of the scanner. The hand scanner is moved by a hand of an operator on the original and reads the image data line by line. The image data representing a dot pattern is transmitted to the main device as an on/off modulated optical signal through a modem. The main device receives the optical signal and demodulates the signal using a modem to reproduce the image data obtained by the hand scanner.
