Optical input and output scanning system
 An optical input and output device which includes laser beam generating means, a photo-conductive drum to be formed with an electrolatent image according to the intensity of a laser beam, scanning means for simultaneously deflecting and distributing the laser beam between the surface of a sheet of paper written with a picture image to be received and the surface of the photo-conductive drum to irradiate and linearly scan the respective surfaces, and photoelectric converting means made receptive of the laser beam reflected from the paper surface thereby to convert it into an electric signal.
