Abstract: After scan conditions are determined by the pre-scan, a temperature of a focus lens unit is measured. When the difference between the measured temperature and a set temperature data stored in a RAM is less than 4° C., a focus position is calculated based on set focus position data in the RAM and temperature correction data which is decided according to the temperature difference. When the temperature difference is 4° C. or more, a focus search operation is carried out to detect the focus position. Focus position data and temperature data, obtained by the focus search operation, are written in the RAM as set focus position data and set temperature data. It is possible to omit the focus search operation if temperature fluctuation is small.

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.
