Abstract
A replenisher supplying apparatus for use in a photographic processor having a processing tank to which pieces of a photosensitive material are consecutively transported for processing, so as to supply replenishers to the processing tank. The apparatus includes stock tanks to which the replenishers are respectively supplied and which are respectively provided with level sensors; pumps for supplying the replenishers from the stock tanks to the processing tank; a controller arranged such that when it is detected by any of the level sensors that the liquid level is at a predetermined level or below, the controller stops the driving of the pump for the stock tank whose solution level has dropped to the predetermined level or below, while the controller continues to drive the remaining pumps until a drop in the level to the predetermined level or below is detected by the remaining level sensors; and a correcting device for correcting the sending capabilities of the pumps on the basis of the amount of each of the replenishers supplied during each of the continuous driving operations of the pumps driven continuously.
