A wide use of computer in the processing of images has been hindered by a high cost of display devices. This paper presents a very inexpensive method for displaying characters and half-tone images. It utilizes dot pattern punched on paper tapes, which are available for most users of minicomputers. Alphanumeric characters are easily displayed by a single tape. The output is also used as an input tape for acknowledging a command at a remote terminal. In such a case, an addition of standard codes under each character makes the decoding easy. The display of an image is obtained by placing many tapes in parallel. A special tape cutter and a board with registration pins make the alignment of tapes easy. The present method is especially suitable to display a computer-generated hologram, in which both the amplitude and the phase are quantized.
