Abstract

A control strip supply apparatus supplies a control strip for inspection of development conditions to a processing tank in a developing machine. The apparatus has a cassette accommodating the control strip, an inside cover of the developing machine on which the cassette is mounted, a guide block provided below the inside cover so as to guide the control strip drawn out of the cassette into the processing tank, and an outside cover which shields the path of the control strip from the cassette to the guide block. Accordingly, the control strip can readily and reliably be supplied into the processing tank while being shielded from light.
