[0024] By adopting the above structure, the interior of the inner shell 11 is divided into three independent areas: a developing chamber 111, a cleaning chamber 112 and a fixing chamber 113, thereby reducing cross-contamination between different processes, and the position of the film developing rack 30 is positioned by the limit groove group, thereby achieving the function of simultaneously positioning the positions of multiple film developing racks 30, thereby avoiding the sliding of the film developing rack 30 and causing multiple groups of films to stick together and cause damage; and through the combined use of the silicone rubber heating plate 14 and the temperature controller 15, the temperatures of the developing chamber 111 and the fixing chamber 113 are accurately adjusted respectively, so that the developing chamber 111 and the fixing chamber 113 reach the predetermined temperature respectively before the film developing rack 30 with the film is loaded, thereby achieving the purpose of developing and fixing the film at a stable temperature, thereby improving the quality of the film.

[0025] Specifically, the operating steps are as follows: developer and fixer are respectively installed in the developing chamber 111 and the fixing chamber 113, and the developer and fixer are heated by the silicone rubber heating plate 14 until they reach a predetermined temperature. Then, the developing rack 30 containing the film is installed in the limiting groove at the developing chamber 111, and the film is immersed in the developer for development. The developed film is placed in the cleaning chamber 112 for washing. The washed film is again installed in the limiting groove at the fixing chamber 113 through the developing rack 30, and the film is immersed in the fixer for fixing. After fixing, it is placed in the cleaning chamber 112 for washing again.
