Compact recording apparatus with functional components mounted on a substrate

摘要

An image recording apparatus for converting a subject image to an image signal and storing the image signal in a memory. An optical unit for focusing the subject image on a focal plane is fixed to obverse surface of a circuit board concentric to an opening of the circuit board that is formed as an optical path through the depth of the circuit board, and an image sensor is fixed to reverse surface of the circuit board concentric to the opening. A sensing surface of the image sensor is directed to the optical unit and is coincident with the focal plane of the optical unit.
