Photosensitive material processing apparatus

A photosensitive material processing apparatus comprising:

• a processing tank in which processing solutions are accommodated;
• a partitioning wall which forms a first processing chamber and a second processing chamber by extending along a vertical direction of said processing tank and partitioning said processing tank, said partitioning wall forming a communicating portion so that a photosensitive material can pass between a lower partitioning wall of said partitioning wall and an upper partitioning wall of said partitioning wall;
• a blade provided at said communicating portion, a vicinity of one end portion of said blade being fixed to said partitioning wall and a vicinity of an other end portion of said blade being provided so as to be able to abut and so as to be able to move apart from said partitioning wall, said blade preventing the mixing of the processing solutions which are respectively stored in said first processing chamber and said second processing chamber, said blade allowing said photosensitive material to be moved from said first processing chamber to said second processing chamber;
• and
• a conveying rack in which a vicinity of one end portion is provided so as to be able to be immersed in and lifted out from said first processing chamber, a vicinity of another end portion is provided so as to be able to be immersed in and lifted out from said second processing chamber similarly to movement of the vicinity of said one end portion, an intermediate portion is provided so as to connect said one end portion and said another end portion, said conveying rack having a plurality of conveying roller pairs, which convey said photosensitive material, and including side plates, which are respectively provided in the vicinity of axial direction end portions of said plurality of conveying roller pairs so as to axially support said plurality of conveying roller pairs, said conveying rack conveying said photosensitive material from said first processing chamber to said second processing chamber via said communicating portion while immersing said photosensitive material into said processing solutions, wherein among said plurality of conveying roller pairs, at least one of the plurality of conveying roller pairs, which are provided in said first processing chamber, is a one-way rotating conveying roller pair which is rotated only in a rotating direction corresponding to a direction of conveying said photosensitive material from said first processing chamber to said second processing chamber.
