ABSTRACT:
The pulse generator comprises a rotating transparent disc having a line pattern along its circumference and which is moved past an equally spaced line pattern of a fixed disc segment. The line patterns are scanned photoelectrically and the light-dark changes are converted into corresponding electrical pulses. The rotating disc and the disc segment are formed of thin plastic sheeting, and the rotating disc has two metal discs secured to respective opposite sides thereof out of the area of the line pattern thereon. One of these discs is formed with a peripheral groove into which the disc segment, which is fixed to a base, extends and bears against the rotating disc. The line patterns are provided on the outer surfaces of the disc and disc segments, whose inner surfaces are in surface-to-surface engagement to slide on each other in the area of the patterns under a slight pressure.
