Abstract

PURPOSE:To supply a stable image bias even if a high-voltage cable is extended long and to suppress the generation of a noise in a signal line involved in the actuation of a device by providing a supporting body for integrally fixing an electric board and an electric cable, CONSTITUTION:The high-voltage cable 11 provided with a contact 12 and a board 10 are fixed on a board base 9 in order and then, assembled in a main body together with the board base 9 in the direction of the arrow A. A high- voltage contact corresponding to the contact 12 exists on the main body side and the contact of the contacts is completed only with the assembling work of the board. In a narrow space, the high-voltage cable 11 is fixed on the base 9 for fixing the board 10 to the device main body, to simplify the assembling work of the device. The base 9 is provided with an opening and the contact 12 can come into contact with the contact of the main body side only by assembling the base 9 in the device. Since the board 10 and a high-voltage base plate are integrally fixed on the board base 9, the distance between the board 10 and the high-voltage cable 11 can be secured even in the narrow space.
