In an automatic film developer, measurements are taken of internal temperature parameters during a warm up phase. Based on measured temperature values a time for completing the warm up phase is calculated. The calculated time for warm up is displayed so that it can be read by an operator. When the calculated time for warm up completion has elapsed, an indication is displayed that the film developer is operational. During the warm up phase, film is not allowed to advance through the automatic film developer. When the calculated time for warm up completion has elapsed, advance of film through the film developer is automatically started.

Automatic developing apparatus and method

A photosensitive material processing apparatus is equipped with a drying section in which a photosensitive material processed with a processing solution is conveyed by a plurality of rollers and dried by drying air from a drying air blowing device. In the photosensitive material processing apparatus, a plurality of heating rollers is disposed to form a part of the above-described plurality of rollers and whose surfaces are heated by a heat source. A control means effects on-off control for the heat source during processing of the photosensitive material to set the surface temperature of each of the plurality of heating rollers and to control the drying air blowing device to lower the surface temperature of each of the plurality of heating rollers by the drying air during a standby period. Accordingly, during the standby period, the surface temperature of each of the plurality of heating rollers is lowered forcibly by the drying air, so that overshooting is restricted.

Photosensitive material processing apparatus

In a temperature control method of a photosensitive material drying device relating to the present invention, a photosensitive material is heated and dried by drying air heated by a heating device. A temperature of a member heated by the drying air is detected, and operation of the heating device is controlled so that the temperature of the member is maintained within a predetermined range. Further, a photosensitive material drying device relating to the present invention includes a heating device supplying heated drying air to an interior of a drying chamber and heating and drying a photosensitive material for which processing by processing solutions has been completed; an exhaust grill through which exhaust air, which is discharged from a vicinity of a conveying path of the photosensitive material to an exterior of the drying chamber, passes; a temperature sensor, disposed at the exhaust grill in a state in which the temperature sensor is shielded from the drying air and detecting a temperature of the exhaust grill heated by the exhaust air; and a temperature control device which controls the heating device in accordance with a temperature detected by the temperature sensor.
