Linear array image sensor with thin-film light emission element light source

A linear array image sensor with a light source, comprising:

• a first substrate made of a transparent plate, said first substrate having a first surface and a second surface;
• two thin-film light emission elements disposed on said first surface of the first substrate and linearly elongated in parallel in a direction to form a slit-shaped window between them;
• a second substrate having two surfaces;
• and
• a plurality of solid-state image pickup elements disposed on one of said two surfaces of the second substrate and linearly aligned along said elongated direction of the thin-film light emission elements,
• said first and second substrates being fixed to and integrated with each other by a transparent material so that light originated by said thin-film light emission elements is emitted from said second surface of said 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 and the slit-shaped window.

A linear array image sensor with a light source, comprising:

• a first substrate made of a transparent plate, said first substrate having a first surface, a second surface and a plurality of side surfaces;
• at least one thin-film light emission element disposed on said first surface of the first substrate and linearly elongated in a direction;
• a second substrate having two surfaces;
• a plurality of solid-state image pickup elements disposed on one of said two surfaces of the second substrate and linearly aligned along said elongated direction of the thin-film light emission element;
• and
• a reflector layer for covering at least one of said plurality of side surfaces of the first substrate,
• said first and second substrates being fixed to and integrated with each other so that light originated by said thin-film light emission element is partially reflected by said reflector layer, emitted from said second surface of said 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.
