Claims

[Claims for Utility Model Registration] A shield case with a bottom wall and both side walls and an open front, a discharge wire stretched inside the shield case, and a shield case that prevents copy paper from entering the shield case. A corona discharge device for an electrostatic copying machine, comprising a plurality of insulating copy paper guide members arranged at intervals in the longitudinal direction of the shield case to prevent corona discharge; , is elastically bent into a substantially U-shape and inserted between the both side walls of the shield case, the center portion is in contact with the inner surface of one of the both side walls, and both ends are positioned on the other inner surface of the both side walls. A long and thin plate-like piece held between the both side walls of the shield case, or elastically curved and inserted between the both side walls of the shield case, with one end attached to the inner surface of one of the both side walls. is composed of a plate-shaped piece positioned on the other inner surface of the both side walls and held between the both side walls of the shield case,
A corona discharge device for an electrostatic copying machine characterized by the following.
