    • PURPOSE: To feed a high-accuracy sheet to be scanned at a constant speed, by performing the main scan with a deflector and the secondary scan through a mechanical shift of a sheet to be scanned.
      CONSTITUTION: A sheet 1 to be scanned is piled on a magazine 2 and held by an air sucking holder 3. Guide plates 4 and 5 are set under the magazine 2, and a sheet supply roll pair 8 containing nip rolls 6 and 7 having contact parts set opposite to each other is provided at a lower opening part formed by the rolls 6 and 7. A pair of nip rolls are set at the position opposite to the surface of a drum 11, and the main scan light C is irradiated so that it goes between these nip rolls. The light C is obtained by polarizing the light beam emitted from a main scanning light source 30 by a polarizing means. Thus the light C scans over the sheet 1 set between nip rolls 12 and 13 in the axial direction of the drum 11.

    • 目的:通过用偏转器执行主扫描并通过要扫描的纸张的机械移位进行辅助扫描,以一定的速度供给要进行扫描的高精度纸张。 构成:将要扫描的片材1堆放在盒子2上并由吸​​气保持器3保持。导板4和5设置在盒子2下方,并且片材供应辊对8包含具有接触的夹辊6和7 在由辊6和7形成的下开口部分设置彼此相对的零件。在与鼓11的表面相对的位置处设置一对夹辊,并且主扫描光C被照射,使得 它们在这些压辊之间。 光C通过偏振装置使从主扫描光源30发射的光束偏振而获得。 因此,光C在卷筒11的轴向上在夹持辊12和13之间设置的片材1上扫描。
