PURPOSE:To eliminate the need for a harness and to economize and to prevent a defect in connection, the breaking of a wire, and noise generation, etc., from being caused by connecting the circuit board of an optical unit, etc., and the entire circuit board directly by their connectors. CONSTITUTION:The connectors 40, 44, and 51 of one circuit board of at least one of an optical write unit, a development unit, a fixation unit, a paper discharge unit, and a cleaning unit, e.g. circuit boards 39, 42, and 49 on the side of the optical write unit and the connectors 53-55 of the entire circuit board 52 which performs operation control over the image forming device and power supply, etc., are coupled directly, therefore, the circuit boards 39, 42, and 49 of the optical write unit and the entire circuit board 52 are connected directly by their connectors, so the harness is not necessary. Consequently, this device is economical and the defect in connection, the breaking of a wire, the generation of noises, etc., are prevented. |
