ABSTRACT:
A miniature coronode charging device comprising a plurality of coronode wires that are slanted with respect to the direction of travel of a charge receptor in order to reduce the effective distance between "hot spots" in the wires and thereby insure uniform charging of the receptor. The length of coronode wires between support points and their conducting contacts is very small, thereby eliminating sagging, singing, tensioning and capacitance problems when providing a corotron charging device of unlimited length. Individual high impedance to the plurality of coronode wires is provided in order to limit the amount of current passing to each of the wires from a high voltage source and thereby reduce the possibility of arcing and damages to the charge receptor. Spacing between coronoa wires and the charge receiving surface is small to provide low corona threshold and self-limiting charging.
