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.
Claims11
A device for recording optical information on a photosensitive material in binary black and white patterns in accordance with digital signals recorded in a digital signal recording medium, said digital signals representing original information in the form of letters and/or figures comprising in combination:
- means for reading said digital signals recorded in the digital signal recording medium and generating binary signals in accordance with the digital signals,
- means for feeding a photosensitive material in synchronization with the reading of said digital signals by said reading means,
- means controlled by said binary signals generated by said reading means for exposing the photosensitive material to light to record black and white patterns in accordance with the binary signals, and
- means for converting said binary signals into visual information in the form of the original information connected with said reading means so that an operator can check the contents of the information actually recorded on the photosensitive material during the operation of recording.
