PURPOSE:To prevent vibration without adjustment with respect to a corona discharger used for an electronic copying machine, etc., by connecting one terminal of a corona wire with the 1st vibrating member vibrating in the same vibration mode as the corona wire and the 2nd vibrating member being connected to the 1st one and capable of vibrating independently. CONSTITUTION:In a spring 1 for applying corona wire tension, a freely movable weight 2 is provided. The spring 1 functions as the 1st vibrating member and when this spring 1 vibrates together with the corona wire 3, the weight 2 functioning as the 2nd vibrating member tends to stop, so force in the reverse direction to vibrations of the spring 1, corona wire 3, etc., operates on the spring 1, corona wire 3, etc. As a result, the vibrations of the spring 1, corona wire 3, etc., attenuate rapidly. |
