<p>PURPOSE:To prevent wave-shaped deformation in a sheet unit, when it is conveyed, by partitioning a suction box, provided being arranged in a subscanning conveying belt, into two chambers of the upstream and downstream sides in a subscanning direction and connecting the chambers to communicate through a thin thickness grooved part. CONSTITUTION:A suction box 104 is provided to be arranged in the inside of a subscanning conveyer belt 96 conveying an accumulating fluorescent material sheet in a subscanning direction C2, and the suction box 104 partitions its inside into subscanning direction upstream and downstream side chambers 106, 108 with a main scanning line serving as the reference, connecting the respective groove-shaped through holes 114 and 116 to communicate through a small thickness notched part 118. When the fluorescent material sheet passes through a scanning part of an image read recording mechanism, the subscanning conveyer belt 96 is displaced to the subscanning direction C2, but here the sheet is sucked first from the through hole 114 by driving the first selector valve 126 next from the through hole 116 by driving the second selector valve 134 while even from the notch 118, and a laser beam 146 is scanned in the main scanning direction. Thus preventing the sheet unit from its corrugated deformation, an image can be high accurately reproduced.</p> |
