ABSTRACT:
Page sensor apparatus for producing a signal related to a thickness of a sheet of paper may comprise a base plate and a foot plate positioned in opposed relation. The base and foot plates are arranged to allow the paper to pass therebetween, so that the base and foot plates become separated by a distance substantially equal to the thickness of the sheet of paper. Capacitance sensing apparatus connected to the base plate and the foot plate senses changes in the electrical capacitance of the base and foot plates and generates an output signal related thereto, the output signal being related to the plate separation, thus paper thickness.
