ABSTRACT:
A small-sized image sensor which does not exert the deleterious influence of soldering, especially, on the light receiving device when attaching a substrate for a light emitting device. A glass cover (11) is attached to the upper portion of a frame (10), and a substrate of a light projecting portion having a light emitting device (12) is fixed to the frame (10) in such a manner as to be inclined toward the glass cover (11). A rod lens array (14) for converging the light reflected from a copy on the glass cover (11) is fixed to the frame (10) in such a manner as to be perpendicular to the glass cover (11). A sensor substrate (16) having a light receiving device (15) is disposed directly under the rod lens array (14), and a hybrid substrate (21) with an electronic part (20) mounted thereon is disposed in a space within the frame (10). The substrates (16) and (21) are connected by a lead frame (22 ) soldered to the bottom surface of the sensor substrate (16). The lead frame also supports the substrate (21).
