  • Photosensitive material processing apparatus and sealing structure for processing section of the apparatus
    Patent number: 6149320
    Abstract: A box-shaped shielding cover is disposed at the surface of a developing solution contained in a developing tank and the bottom wall of the cover ensures that contact between the developing solution and the air is kept to a minimum and that deterioration of the processing solution due to carbon dioxide and evaporation of the water are controlled. Moreover, the close contact between the top portion of the peripheral wall of the shielding cover and the top cover covering the top portion of the PS plate processor cuts off the flow of air over the developing tank (the air flowing from the insertion aperture to the discharge aperture). Accordingly, the airtightness of the seal in the developing section is enhanced, there is minimal deterioration of the developing solution due to carbon dioxide, and the rate of replenishment of the developing solution is reduced.
