Abstract

A data processing source S is connected to a photoelectric (PE) paper tape reader R, with PE calls, for a NC (numeric controlled) controller C for a machine tool T, by an array of light-emitting diodes (LEDS) bypassing the use of the paper tape. The LEDS L are installed directly over PE cells P, and each is turned on to simulate a hole or off to simulate the absence of a hole. Eight LED's L provide for tape channels. One LED illuminates the sprocket PE cell P which provides synchronization. The LED's L are spaced on 0.100'' centers. Fiber optics can be interposed between sources L and cells P, to permit spacing larger LED's L farther apart or flexibility of placing LED's.
