ABSTRACT:
Original information is converted to digital signals and recorded on a digital signal recording medium such as a paper tape. The digital signal recorded on the tape or the like is converted to binary signals. A photosensitive material is fed in synchronization with the conversion of the digital signal to binary signals. The photosensitive material is exposed to light from a light source controlled in accordance with the binary signals. In a preferred embodiment of the invention, a print out typewriter is connected with the circuit which converts the digital signals to the binary signals to print out the information being recorded on the photosensitive material on an output sheet in the form of the original information.
