PURPOSE:To make electrical connection perfect, to reduce mulfunction caused by the entrance of noise from the outside and to facilitate attaching and detaching by providing an input part from a control part CPU, a power source or the like to the surface of the outside peripheral part of a substrate as a connection electrode. CONSTITUTION:The plural connection electrodes 28 are provided to one end of the outside peripheral part of the substrate 23, which is also used as a supporting substrate and where a printed circuit is provided, as the input part from the CPU, the power source or the like. Notches 29 are provided to both ends of the peripheral edge of the substrate 23 where an LED array is provided and used for positioning when the substrate 23 is loaded to a destaticization device main body. The body end parts of the substrate 23 of the destaticization device 2 are inserted in a loading direction shown by an arrow so that they are interposed by the connecting units 34 of a copying machine main body. Besides, they are pressed and inserted until the notches 29 are engaged with a pin or a projection and correctly positioned. The connecting units 28 are electrically connected by the connecting units 34. |
