A laser beam emitted from the oscillator is directed at the polygon mirror which rotates at a high speed and is synchronized by clock pulses. The direction of the beam reflected by the mirror is changed via the collimator lens and aims straight at the workpiece. As the polygon mirror rotates, the horizontal laser beam travels across the receiver and, if it is not obstructed by a workpiece, reaches the receiver. The output voltage of the photoelectric element varies proportionally with the amount of light which reaches the photoelectric cell. The timed pulses generated during the beam obstruction by the workpiece represent the dimension of the workpiece.
