A simple high-speed computer paper tape supply
Arthur E. Renshaw · Journal of Physics E Scientific Instruments · 1970
Experience in this laboratory of high-speed paper tape punches (Tally Model P-120), connected as the output of a computer (Ferranti Argus 500), has shown that punching errors arising from a mechanical origin are frequent. If the tape supply is arranged to be `drag free', these errors are almost eliminated, thus avoiding costly waste of operator and computer time. This note describes a prototype of a high speed tape supply device which was designed for use with an 8 hole 120 character per second paper tape punch. The device is simple and inexpensive to construct, and has proved reliable in use.
