Abstract:
1. A line sensor comprising two photodiode portions each divided into a plurality of element regions at a predetermined pitch along the lengthwise direction thereof, a charge transferring device provided corresponding to each of the photodiode portions for receiving and transferring the charge from each said corresponding photodiode portion, and a transfer gate disposed between each said photodiode portion and the charge transferring device corresponding thereto, wherein the two photodiode portions are provided adjacently in the widthwise direction perpendicular to the lengthwise directions thereof with a microscopic gap therebetween and the charge transferring device corresponding to each of the respective adjacently disposed photodiode portions is provided on the exterior side of the width direction the photodiode portion corresponding thereto, and the width of the each of the photodiode portions is 50-500 μm, wherein the positions of the element regions of each photodiode portion can be mutually offset along the lengthwise direction thereof.
