Abstract

Illustrated in Figures 1 and 2 is a corona discharge device comprising a subassembly 70 including an insulative, generally rectangular-shaped frame member 72. A corona wire 27 is permanently secured to the frame member such that together with the frame member and a pair of corotron caps (not shown) they form the subassembly 70. Each end portion 74 of the structure 70 has secured thereto a clip member 76 adapted to receive a ball stud 78 forming an integral part of an optics module (not shown). Thus, the subassembly can be readily attached to and detached from the optics module 80 which forms a permanent part of the machine.

CORONA DISCHARGE DEVICE (Cont'd)

Illustrated in Figures 1 and 2 is a corona discharge device comprising a subassembly 70 including an insulative, generally rectangular-shaped frame member 72. A corona wire 27 is permanently secured to the frame member such that together with the frame member and a pair of corotron caps (not shown) they form the subassembly 70. Each end portion 74 of the structure 70 has secured thereto a clip member 76 adapted to receive a ball stud 78 forming an integral part of an optics module (not shown). Thus, the subassembly can be readily attached to and detached from the optics module 80 which forms a permanent part of the machine.

Once installed, the subassembly cooperates with the generally, U-shaped con- ductive shield 26 to form the corona discharge device. As can be seen in Figure 1, when the subassembly 70 is in place, each leg portion 82 of the U-shaped shield is disposed intermediate side walls 84 of the frame 72 and the corona wire 27, the wire being suitably spaced from the leg portions 82 and a top wall 86 of the shield to produce the desired distribution of current flow between the wire and the shield and between the wire and a photoconductive belt (not shown).
