Abstract
A linear solid-state image sensor includes a first chip and a second chip, each of the first and second chips having a long substrate, a plural number of photo-responsive elements formed in a line on the substrate, an analog switch circuit driving the photo-responsive elements, and a shift register shifting signal to make the analog switch circuit successively effective. The second chip is mechanically connected to the first chip so that a shift direction of the shift register circuit is in agreement with a shift direction of the shift register circuit of the first chip. The linear solid-stage image sensor further includes an external wiring connecting a first stage of the shift register circuit of the first chip and a final stage of the shift register circuit of the second chip, and an input wiring being formed on the substrate of the second chip and leading signal input from the terminal at the end of the side opposite a connection portion with the first chip to a first stage of the shift register circuit of the second chip.
