Photosensitive material treating apparatus

Abstract

A photosensitive material treating apparatus comprises a bulkhead provided between a plurality of treating tanks in which treating liquid is stored, and having an opening through which a photosensitive material is passed, an elastic blade which abuts against an opening wall of the opening to close the opening, arresting leakage of the treating liquid and, at the same time, which is elastically deformed to allow a photosensitive material to be passed, and a mounting member for mounting the elastic blade on a peripheral wall of the opening. The mounting member has a smaller linear expansion coefficient than that of the elastic blade, and is integrally formed with the elastic blade.
