Abstract
A corona discharge device including a shield case having a bottom wall and a pair of walls extending from both side ends of the bottom wall and a wire stretched within the shield case. A guide member for preventing entry of a sheet material into the shield case has a guide arm portion extending across an opening of the shield case, and the free end portion of the guide arm portion is kept in elastic press contact with the wall of the shield case. Furthermore, the guide member for preventing entry of the sheet material into the shield case has one end portion fixed to one wall of the shield case and its other end portion detachably anchored selectively at one wall and the other wall of the shield case.
Claims8
A corona discharge device provided with an electrically conductive shield case having a bottom wall and a pair of walls extending from both side ends of the bottom wall, a wire set in a stretched state within the shield case and a guide member for preventing entry of a sheet material into the shield case, wherein the guide member has a securing portion to be detachably mounted on one wall of the shield case and a guide arm portion extending from the securing portion to the other wall of the shield case across an opening formed in the shield case, the guide arm portion being in press contact with the upper edge of the other wall of the shield case by elastic deformation.
A corona discharge device provided with an electrically conductive shield case having a bottom wall and a pair of walls extending from both side ends of the bottom wall, a wire set in a stretched state within the shield case and a guide member for preventing entry of a sheet material into the shield case, wherein the guide member is formed of an elastically deformable film-like material with one end portion being fixed to one of the walls of the shield case and the other end portion being detachably anchored selectively at said one wall and the other wall, and when the other end portion of the guide member is anchored at the other wall, the guide member extends from one wall to the other across an opening formed in the shield case, and when its other end portion is anchored at said one wall, the opening of the shield case is exposed.
