Abstract
PURPOSE: To accurately replenish developing solution without causing time lag by detecting the area of the films to be treated and replenishing the forecast required amount as well as by actually measuring the blackening area and performing required replenishing.
CONSTITUTION: The film to undergo development processing is detected 4 of its film area before it enters a developing tank 1. The signal thereof is amplified 7 and is sent together with the signal from a blackening area rate selecting mechanism 8 to a forecast blackening area and forecast replenishing solution amount calculating mechanism circuit 9. When the required replenishing solution amount is calculated in this calculating mechanism circuit, the replenishing solution is supplemented 13 for the specified time by the signal thereof. Next, the blackening area of the film after the development processing is measured 15 and the signal thereof is amplified 16, thence the replenishing solution amount actually required is calculated 17. This signal is applied to a replenishing amount correcting circuit 12 and is compared with the signal from a voltage control mechanism circuit 10, based on the signal whereof the replenishing 13 is corrected.
