DISPOSABLE CORONA DISCHARGE DEVICE

摘要

A corona discharge device including a throw-away subassembly which is inexpensive and can therefore be discarded when it becomes ineffective for its intended purpose. The subassembly can be readily installed into the printing machine in which it is used. It comprises a generally rectangular-shaped insulative frame and a tungsten wire. When the subassembly is inserted into the machine, it cooperates with a generally Ushaped, conductive shield which is an integral part of the machine to form the corona discharge device.
