<p>PURPOSE:To record a desirable image by delivering a sheet body positively without unevenness in conveyance from an auxiliary scanning part provided at the sheet bode feeding device of an image recording device using laser beams. CONSTITUTION:A sheet body feeding device 2 is formed of an auxiliary scanning part 7 for feeding a sheet body (photosensitive material) 10 out to an exposure recording part 9 orthogonally to main scanning scanned by laser beams 8, plural pairs of carrier rollers 3 for conveying the photosensitive material to the auxiliary scanning part 7, upper and lower guide plates 4 and a detecting means 6, and its carrier path is curved in the carrier direction. At the time of being conveyed to the auxiliary scanning part 7, the photosensitive material 10 is conveyed being held by the respective carrier roller pairs 3. When the photosensitive material 10 is delivered out of the auxiliary scanning part 7, switching is performed so that the holding of the respective carrier roller pairs 3 is released to lift the lower guide plates 4b and the photosensitive material 10 is delivered out by the conveyor means of the auxiliary scanning part 7 and the guide faces of the guide plates 4b. The photosensitive material 10 is thereby sent out by the independent precision conveyor mechanism of the auxiliary scanning part 7, the smooth face of the guide plates 4 and the curved carrier path, so that unevenness in conveyance can be prevented.</p> |
