PURPOSE:To develop short sized photographic films automatically with a required min. amt. of chemical soln. by setting the film to be developed and supplying and discharging the chemical soln. for development of adequate temp. and washing water at constant timings. CONSTITUTION:An opening-closing cover 28 is opened, and a film 1 to be developed is set to a patrone supporting pin 29. The leading end of the film is inserted between rolls 30 and 31, and the cover 28 is closed after which a knob 37 is turned to feed the film into a developing chamber 21. A specified amt. of a developing chemical soln. is fed into a storage tank 41 by opening a plug 43. The hot water delivered out from a hot water generating facility 60 rises to the temp. suited for development and at the point of the time when the chemical soln. in the tank rises to adequate temp., a compressor 84 connected to the tank 41 is operated to circulate the chemical soln. in the chamber 21 from the tank 41. Upon lapse of the required time, the pump 82 is stopped, and a solenoid valve 24 is opened to discharge the chemical soln. |
