To prevent an alarm for frequent feed water from being issued.

This feed water alarm device only stores the lowering of the liquid level of a feed water tank detected by a liquid level sensor 76 when the liquid levels of respective processing solution tanks such as feed water tank and a developing tank, etc., reach respective specified levels in the case of the startup of an automatic developing device. Display for feed water is performed in a condition that the lowering of the liquid level of the feed water tank is stored when the lowering of the liquid levels of developing tank, etc., are detected by a liquid level sensor 78, etc., and when the start of the sheet film processing is detected by an insertion detection sensor, so that frequency for issuing the alarm for the feed water is restrained when the display is performed based on the detection result of the sensor 78. That is, the on/off frequency of a faucet is restrained.
