FIG. 1 is a sectional view of the charger of the copying machine of this embodiment. Approximately U-shaped seal 1 made of conductive material Insulating supporting portions 2.3 are provided at both ends of the case 1 in the longitudinal direction, and the charged wire 4 is connected to the insulating supporting portions 2.3 through a spring 6 at one end. , and the other end is attached to the high voltage electrode plate 8 via the spring 7. The configuration and operation of this variable height insulating member 9 will be explained in detail with reference to FIG. 2. In FIG. The insulating member 10 has a 1I11 yen on the upper part to regulate the position of the charged wire, and the boundary surfaces of the insulating member 10 and 11 have an angle of 1I1 with respect to the horizontal direction. It can be moved horizontally by rotating the insulating part 1.
00 Due to the insulating section's low efficiency, it cannot be moved horizontally, but can slide vertically. Therefore, by rotating the screw 13, the insulating member 11 is moved in the horizontal direction A.
When moved to B, the insulating part moves in the downward direction CD due to the sloped boundary surface. Therefore, the height of the charging wire can be easily changed.
次に本発明の第２の実施例について説明する。Next, a second embodiment of the present invention will be described.

る。In Fig. 3, the insulating height variable member is Vjt as follows.
It is made and works. The insulating member 14 is a disc-shaped member having a groove on its circumferential surface for regulating the position of the charged wire 4, and a screw 16 is fixed to an offset position of the insulating member 14, so that it can rotate together with the screw 16. The screw 15 is pivotally supported by the insulating member 16, and by rotating the screw 15 in the left-right direction EF, the distance from the box surface of the insulating part 160 to the top of the insulating member 14 can be changed. . This allows the height of the line to be easily changed in the vertical direction GH. The same effect can be obtained even if the above-mentioned charging wire height iiJ members 9 and 14 are incorporated in advance into the charging wire surface height regulating square 17.18.
