Abstract

A capacitive checking apparatus in a sheet feeding machine for checking the absence of a sheet and/or the presence of multiple sheets comprises a capacitor (5) formed of two capacitor plates (3) and an evaluating circuit (7, 8). The capacitor plates (3) are arranged in one plane separated by a gap (4). <IMAGE>
