Abstract
A flow sensor detects a flow rate of cooling air from a compressor, and a determination is made as to whether or not the detected flow rate is abnormal. A determination is made by a diaphragm position sensor as to whether or not a diaphragm is located at such a critical position that a quantity of light illuminated onto a photographic film is large, possibly resulting in degeneration of a photographic film. A lamp is turned off if the diaphragm is located at the critical position and the flow rate of the cooling air is abnormal.
