自動現像機においては、各種の写真のネガフイ
ルムや印画紙等の感光材料の処理が行なわれる。
この感光材料の処理は一般に露光ずみの感光材料
を現像、定着、水洗及び乾燥の各工程に順次送り
込んで処理している。[Prior Art] Automatic processing machines process photosensitive materials such as various photographic negative films and photographic papers.
Generally, the photosensitive material is processed by sequentially sending the exposed photosensitive material through development, fixing, washing, and drying steps.
ところで、このような処理が行なわれると、現
像処理工程においては、感光材料を現像液槽中に
移送して処理が行なわれるため、現像液が疲労し
たり、液量が減少する。 By the way, when such a process is performed, the photosensitive material is transferred into a developer tank and processed in the development process, so that the developer becomes exhausted or the amount of the developer decreases.
従つて、この疲労した現像液を回復させたり、

よつて低下することがある。 Therefore, it is necessary to recover this exhausted developer,
Replenishment is required to increase the amount of developer that has decreased. Furthermore, even if the photosensitive material is not processed, the activity of the developer may decrease during storage due to air oxidation.
このため、自動現像機では、例えば一定の時間
間隔等で自動的に現像液を補充して、現像液が常

は、長期間の感光材料の処理等によつて現像液の
液状態が変化するため、自動的に現像液を補充す
る補充量を補正する必要がある。[Problems to be Solved by the Invention] By the way, in order to maintain the finishing performance of a photosensitive material at a high level by appropriately replenishing the developer, it is necessary to reduce the amount of the developer by processing the photosensitive material for a long period of time. Since the conditions change, it is necessary to automatically correct the replenishment amount of the developer.

よつて生じるコントロールストリツプの黒化また
はドツトの変化量から現像液の液状態を測定し
て、現像液の補充の補正を行ない、液状態に応じ
た管理が行なわれている。 For this reason, in recent automatic developing machines, the control strip is processed at predetermined time intervals, and the state of the developer is measured from the amount of blackening or dot change in the control strip caused by this processing. The replenishment of the developing solution is corrected and management is performed according to the state of the solution.
ところで、例えば、コントロールストリツプの
変化量に対し、過去の経験と勘により現像液の補

現像液の総補充量とに関係があり、次の２次関数
の式で表わすことができる。Calculation formula for automatic developing machine with 60 liters of developer First, the amount of excess or shortage of replenishment (Y%) is determined by the amount of developer and the amount of change in the control strip.
It is related to the total amount of developer replenishment, and can be expressed by the following quadratic function.
Ｙ＝0.45X・Ｘ＋1.95X＋1.86
この２次関数の式において、定数はそれぞれ現

像液の総補充量によつて変化するから、変数Ｘは
次のようにして求める。 Furthermore, since the amount of change in the control strip changes depending on the total amount of developer replenishment, the variable X is determined as follows.
Ｘ＝コントロールストリツプ変化量／総補充量

トリツプ変化量が、基準値より小さい場合には過
多と判断され基準値より大きい場合には不足と判
断される。X = control strip change/total refill amount In this way, the amount of over or under replenishment (Y
%) can be determined, and whether there is too much or too little replenishment is determined by comparing the amount of change in the control strip with a reference value. That is, if the amount of change in the control strip is smaller than the reference value, it is determined to be excessive, and if it is greater than the reference value, it is determined to be insufficient.
補充が過多と判断されると、次のようにして補
正係数を求める。 If it is determined that replenishment is excessive, a correction coefficient is determined as follows.
まず、過多量を求める。 First, find the excess amount.
過多量＝［Ｙ／（Ｙ＋100）］×総補充量
次に、この過多の場合の補正係数（MDC）を
求める。 Excess amount = [Y/(Y+100)] x total replenishment amount Next, the correction coefficient (MDC) in the case of this excessive amount is determined.
MDC＝（総補充量−過多補充量）／総補充量
一方、補充が不足と判断されると、次のように
して補正係数を求める。MDC=(total replenishment amount - excessive replenishment amount)/total replenishment amount On the other hand, if it is determined that replenishment is insufficient, the correction coefficient is calculated as follows.
まず、不足量を求める。 First, find the amount of shortage.
不足量＝［Ｙ／（100−Ｙ）］×総補充量
次に、この不足の場合の補正係数（MDC）を
求める。 Shortage amount = [Y/(100-Y)] x total replenishment amount Next, find the correction coefficient (MDC) in case of this shortage.
MDC＝（不足補充量＋総補充量）／総補充量

The correction coefficient is calculated by calculating the amount of replenishment over or under the appropriate replenishment amount from the total replenishment amount of developer replenishment performed during lip processing and the amount of developer in the developer tank. Since the standard replenishment amount is corrected by multiplying the standard replenishment amount by the calculated correction coefficient, even after the amount of change in the control strip is detected, the developer is can be maintained and managed with high precision.
