ABSTRACT:
A contact image sensor has in an upper portion of a housing a rod-like continuous light source for emitting light directly to an object. The continuous light source is coated, over its entire outer glass surface, except at an irradiating portion, with a black paint to eliminate irradiation of unnecessary light. Inside the housing, there are accommodated a condenser lens for concentrating the reflected light from the object, and a sensor board on which sensor chips and various electronic components such as logic ICs are arranged, each sensor chip being composed of a light-receiving portion for receiving the light concentrated by the condenser lens and a driver circuit. The passageway of the reflected light from the object is occupied by a transparent resin to prevent any foreign matter from entering from the surroundings.
