PURPOSE:To correct the position shift of the light irradiation area of a light source by restraining the movement of a light source support body by a frame body positioning means while the light source support frame body is supported movably by a frame body support means and its position is adjusted. CONSTITUTION:The light source support frame 13 of an eraser device main body 11 is supported by the frame supporting means 20 movably almost orthogonally to an image forming direction, i.e. in the array direction of the light source 12. This frame body supporting means 20 consists of a connector 16 and a connector base 21 which supports the connector 16 movably. Further, the frame body positioning means 30 consists of a positioning nut 31 arranged on a connector support plate 22 and an adjusting shaft 32 which displaces the positioning nut 31. Then while the position of the light source support means 13 relative to the frame body support means 20 is adjusted, the movement of the light source support frame body 13 is restrained. Consequently, the position shift of the light irradiation area of the light source of the eraser device main body 11 can be corrected. |
