DRY WIND CONTROL METHOD FOR AUTOMATIC DEVELOPING MACHINE AND AUTOMATIC DEVELOPING MACHINE

PURPOSE:To stabilize the dimensional fluctuation of a processing film before and after a drying treatment by delaying the start of humidification as far as possible in such manner that the humidity in a drying section can be controlled to a set value at the point of the time when the film enters the drying section in the case of the humidification control of drying wind. CONSTITUTION:The temp. and humidity of the outdoor air are detected and the temp. and humidity of the drying wind are controlled in accordance with the detected information. The humidification is started by delaying the same as far as possible in such a manner that the humidity in the drying section can be controlled to the set value at the point D of the time when the film enters the drying section in the case of the humidification control of drying wind. Since the temp. and humidity simultaneously attain the set values at the point D of the tie when the film enters the drying section, the relative increase in the humidity in the drying section is obviated and the humidity sensor for the outdoor air can detect the exact humidity conditions of the outdoor air. The dimensional fluctuation of the film before and after the drying is stabilized in this way.
