Patent ID: 7460163

Claim:
A line sensor in which an N (N is an integer of 2 or more) pixel parts are arranged in one direction, characterized in that it comprises: an image pick-up part, comprising said N pixel parts each comprising an M photosensitive regions (M is an integer of 2 or more) in that charge is generated and accumulated in response to an incident energy beam, which outputs the charges generated and accumulated by said M photosensitive regions that each said N pixel parts comprise; a charge integrator, comprising an N integrators, to which the charges generated and accumulated in said M photosensitive regions that an nth (n is any integer of 1 or more and no more than N) pixel part of said image pick-up part comprises are input, and which integrates and accumulates the input charges in an nth integrator, and outputs all of the charges integrated and accumulated in each said N integrators in a batch; and a charge output part, comprising an N output parts, to which the charges output from said nth integrator of said charge integrator are input, and which accumulates the input charges in an nth output part, and outputs the charges accumulated in each said N output parts in sequence.
