Abstract
Abstract A complete close-contact type image sensor which comes into contact with an original and reads information from the original and which includes a sensor element for photoelectro conversion of a light signal reflected from the original and electronic parts such as a driven unit for driving the sensor element and taking out an electric signal stored in the sensor element, the image sensor being characterized in that the electronic parts such as the driving unit are disposed inside a plane including the surface of contact with the original. According to the above construction of the present invention, since the electronic parts, including the driving unit, are disposed inside the plane which includes the surface of contact with the original, the path of transfer of the original can be made rectilinear to stabilize the feed of the original without enlarging the gap between the sensor element and the original.
