Abstract: <P>PROBLEM TO BE SOLVED: To obtain an image recorder in which image data of a number of lines required for single main scanning is stored in a main image developing board and transferred to a sub-image developing board with no lag.  <P>SOLUTION: Since an exposure control system can be constituted of a board arrangement adapted to a current device specification, a large distribution board is not required to be prepared in accordance with a maximum number of channels and thereby the size of the image recorder can be reduced. Since it is simply required to suspension connect a sub-image distribution board 166 through a harness 170 based on the circuitry of a minimum number of channels, troubles in work efficiency, e.g. replacement of all circuits depending on the number of channels in a device specification, can be eliminated. Furthermore, replacing work incident to alteration of device specification becomes convenient because a main image distribution board 154 or the sub-image distribution board 166 is integrated with an exposure optical system control board 162.  <P>COPYRIGHT: (C)2004,JPO
