PURPOSE:To simplify a mounting work, and a main body structure, by mounting a supporter in which a lens guiding hole to fix an optical lens at a prescribed position at the upper part of the light rceiving plane of a photoelectric transducer is provided. CONSTITUTION:A supporter 24 is fixed at a circuit substrate 21 so that a lens guiding hole 29 is located at the upper side of the light receiving plane of a photoelectric transducer 26, through circuit substrate fixing claws 24a and 24b. An optical lens 32 is fixed in a state that it is inserted in the lens guiding hole 29 of a contact type image sensor, and the contact type image sensor is fixed at a main body 31 through a sensor supporter 33. In this way, it is made unnecessary to perform the alignment for positioning between the optical axis of the optical lens 32 at the mounting time of the contact type image sensor, and the optical lens 32 at the main body 31, and the light receiving plane of the photoelectric transducer 26 of the contact type image sensor.
