第５項までのいずれかに記載のコロナ放電機。[Claims for Utility Model Registration] 1. A casing made of a metal material; an insulating support member provided at both ends of the casing, at least one of which is movable in directions toward and away from the other; a wire stretched between the support members; a positioning means for positioning the one support member at a wire attachment position when the wire is stretched; a tension applying means for applying tension to the wire by moving it in a direction away from the other support member; and an elastic biasing means interposed between the one support member and the tension application means. A corona discharger is provided. 2. The tension applying means includes a movable member mounted so as to be movable in directions approaching and away from the one support member, and an operating member for moving the movable member in a direction away from the one support member. and the elastic biasing means is interposed between the movable member and the one support member.
Corona discharger described in section. 3. The operating member is attached to the casing so as to be pivotable between a tension applying position where tension is applied to the wire and a tension releasing position where tension is substantially released from the wire, and the operating member is mounted in the tension applying position. when the movable member is moved in a direction away from the one support member, the one support member is thereby moved in a direction away from the other support member via the elastic biasing means. 2. The corona discharge device according to claim 2, wherein the wire is tensioned by the action of the elastic biasing means. 4. The corona discharger according to claim 3, which is provided with locking means for releasably locking the operating member in the tensioning position. 5. The corona discharger according to claim 3 or 4, wherein the operating member covers above the one support member when in the tension applying position. 6. The corona according to any one of claims 3 to 5 of the utility model registration claim, wherein the casing is provided with a rotation prevention means for preventing the operation member from rotating beyond the tension release position. discharge machine.
