Abstract

Signal charges generated by a plurality of photoelectric conversion elements are transferred to first and second horizontal charge transfer registers via corresponding vertical charge transfer registers. The first and second horizontal charge transfer registers transfer the signal charges to first and second output portions, respectively. The first and second output portions convert the signal charges into voltages. The first and second output portions respectively include first and second signal charge detectors, first and second transistors each having a source, a drain, and a gate, and first and second charge sweeping regions, each having a charge sweeping control gate and a charge sweeping drain. The first signal charge detector, the source, the drain, and the gate of the first transistor, and the charge sweeping control gate and the charge sweeping drain of the first charge sweeping region are almost congruent to the second signal charge detector, the source, the drain, and the gate of the second transistor, and the charge sweeping control gate and the charge sweeping drain of the second charge sweeping region, and the former components are overlaid almost completely on the latter components by a translational movement.
