  • Photosensitive material processing apparatus in use with a solid processing agent
    Patent number: 5508777
    Abstract: A photosensitive material processing apparatus for processing a photosensitive material such as a photographic film and a photographic print in use with a solid processing agent. The apparatus includes: a processing tank for processing the photosensitive material; a processing agent accommodating chamber for accommodating the solid processing agent; a pump for circulating a processing solution between the processing tank and the processing agent accommodating chamber; and a processing agent supply for supplying the solid processing agent to the processing agent accommodating chamber. The processing agent accommodating chamber includes a processing agent dissolving member which further includes a processing agent support member for supporting the solid processing agent. A sectional area of the processing agent support member is increased as it comes to a lower portion of the processing agent supporting member.
