PROBLEM TO BE SOLVED: To make a photograph processor cope with a case that the number of types of enlarging lenses becomes over the number of types which can be discriminated by a sensor as the photograph processor constituted so that the type of the loaded enlarging lens can be automatically discriminated. SOLUTION: An identical code is given to the plural type of enlarging lenses by being made to overlap and only the prescribed number of enlarging lenses whose using frequencies are expected to be high is registered to the photograph processor. When the enlarging lens which is not registered is used and the code thereof overlaps the code of the enlarging lens which is already registered, the lens substrate of the enlarging lens is exchanged for a general-purpose lens substrate 552' and an aperture 558 formed at the substrate 552' is properly blocked by a cap 560 so as to set an optional binary code selected by a user.
