Abstract

PURPOSE:To make it possible to obtain a pulse generator of simple constitution using one light emitting element and two photo detectors, by making photo detectors convert photoelectrically a light beam emitted by light emitting element through a slit by turning a shielding plate. CONSTITUTION:As shielding plate (a) is rotated clockwise as shown by arrow X, beam i1 of beams i1 and i2 emitted from light emitting element (e) passes over slit (d) and is projected on photo detector f1, a signal from which is amplified g1 and outputted h1 while beam i2 is cut off by plate (a). Next, as the rotation of plate (a) advance, beam i2 is outputted h2 and beam i1 is cut off by plate (a). On the other hand, turning plate (a) in the clockwise direction obtains an output of a series of out-of-phase pulses. Consequently, a pulse generator of simple constitution can be obtained which uses one light emitting element and two photo detectors.
