Abstract
A device for counting objects in a stacked relationship which includes a bifurcated optical cable, a light source for directing light through the bundle at the stack and a sensor for generating a signal proportional to the light reflected by the stack. The signal is digitized and fed to a digital counter. Various displays connected to the counter indicate the count results.
