Abstract
A linear array image sensor with a light source, includes a first substrate made of a transparent plate, which has a first surface and a second surface, at least one thin-film light emission element disposed on the first surface of the first substrate and linearly elongated in a direction, a second substrate having two surfaces, and a plurality of solid-state image pickup elements disposed on one of the two surfaces of the second substrate and linearly aligned along the elongated direction of the thin-film light emission element. The first and second substrates are fixed to and integrated with each other by a transparent material so that light originated by the thin-film light emission element is emitted from the second surface of the first substrate and reflected by an image carrier to be detected, and that the reflected light is applied to the plurality of the solid-state image pickup elements through the first substrate.
