PROBLEM TO BE SOLVED: To suppress the increase of a production cost which may arise from the execution of an antimicrobial treatment. SOLUTION: The machine frame 14 of a PS plate (photosensitive planographic printing plate) processor 10 is circumferentially enclosed by outside plate panels 76a to 76G. The processing liquid processing section of the PS plate processor is disposed in a frame 20 of a box body shape of which the upper opening is closed, with a top cap 70 and which is enclosed by an insertion table 16, side covers 72, 74 and the outside plat cover 76G provided with a discharge port 104. This frame is subjected to an antimicrobial treatment by pressing of antimicrobial stainless steels uniformly distributed with copper as a simple substance. As a result, the sure antimicrobial treatment may be executed at the cost lower than the cost of molding by antimicrobial resins or applying of an antimicrobial coating material. |
