Image sensing device and image reading apparatus using same |
摘要 |
<p>An image reading apparatus, having RGB photoreceptors comprising a CCD line sensor, reduces influence of color mixture due to intrapixel transfer in which electric charges from a photoreceptor are transferred via another photoreceptor. The RGB photoreceptors are provided close to each other in parallel, between CCD shift units corresponding to the photoreceptors. The electric charges generated at the G photoreceptor and the B photoreceptor are directly transferred to the CCD shift units. The electric charges generated at the R photoreceptor are transferred to the CCD shift units via the B photoreceptor. That is, the electric charges generated at a photoreceptor having a larger electric charge-generating characteristic are transferred via a photoreceptor having a smaller electric charge-generating characteristic. Further, a transfer direction in which the electric charges are transferred and a subscanning direction in which an original is conveyed upon reading by the photoreceptors are in the same direction. Thus the amount of color mixture can be reduced. <IMAGE></p> |
