Device for preventing the degeneration of a photographic photosensitive material and image reading apparatus

   
   

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.

Датчик подачи обнаруживает тариф подачи охлаждая воздуха от компрессора, и определение сделано as to whether или не обнаруженный тариф подачи анормалн. Определение сделано датчиком положения диафрагмы as to whether или не диафрагма расположена на таком критически положении количество света осветило на фотографическую пленку большое, по возможности resulting in вырождение фотографической пленки. Светильник повернут если диафрагма расположена на критически положении и тариф подачи охлаждая воздуха анормалн.
