Abstract:
1. An exposure device comprising: a plurality of light emitting elements that emit light which an exposure target member is exposed to; a driving circuit that performs at least one of a first drive operation and a second drive operation, the first drive operation being an operation of receiving a plurality of image signals, which have been supplied, corresponding to the plurality of light emitting elements and of individually driving, for use in exposure to light, the plurality of light emitting elements in accordance with the plurality of image signals, the second drive operation being an operation of receiving supplied light-amount adjustment control signals used to control amounts of light and of individually driving, for use in adjustment of the amounts of light, the plurality of light emitting elements in accordance with the light-amount adjustment control signals; an image-signal connector that has a plurality of terminals connected to a plurality of core wires of an image-signal cable, and that relays, to the driving circuit, the plurality of image signals which have been transmitted through the image-signal cable, the image-signal cable being a cable in which the plurality of core wires through which the plurality of image signals are transmitted are arranged at a first pitch and which is formed so as to have a sheet shape; a power connector that has a plurality of terminals which are arranged at a pitch substantially wider than the first pitch, and that relays, to the driving circuit, power which has been transmitted through a plurality of power cables, each of the plurality of terminals of the power connector being connected to a corresponding one of core wires of the plurality of power cables through which power is transmitted; and an adjustment-control-signal connector that has a plurality of terminals which are arranged at a pitch substantially wider than the first pitch, and that relays, to the driving circuit, the light-amount adjustment control signals which have been transmitted through a plurality of adjustment-control-signal cables, each of the plurality of terminals of the adjustment-control-signal connector being connected to a corresponding one of core wires of the plurality of adjustment-control-signal cables through which the light-amount adjustment control signals are transmitted.
