中で搬送を停止される不具合を生ずることになる。Replenishment processing liquid is supplied to each processing liquid to compensate for evaporation and fatigue. Therefore, waste liquid is taken out from each treatment tank and stored in a waste liquid tank. This waste liquid tank is equipped with a sensor that detects the full liquid level and issues an alarm. Therefore, if the waste liquid tank is not replaced immediately after this alarm is issued, waste liquid will overflow from the tank. In addition, if the waste liquid tank is not replaced, it is necessary to stop the developing device, but since the photosensitive material being developed is inserted into the developing device, there is a problem that the conveyance of the photosensitive material is stopped midway through development. will occur.
本発明は上記事実を考慮し、廃液タンクから廃液タンク
交換の警報が発せられた場合であって、廃液タンクを交
換しない状態でも廃液タンクから廃液が溢れたり、現像
処理中の感光材料に不具合を生ずることがない現像装置
運転方法を得ることが目的である。In consideration of the above facts, the present invention has been developed in the case where the waste liquid tank issues an alarm to replace the waste liquid tank, and even if the waste liquid tank is not replaced, the waste liquid may overflow from the waste liquid tank or cause problems to the photosensitive material during the developing process. It is an object of the present invention to obtain a method of operating a developing device that does not cause the above problems.
本発明は、感光材料処理槽からの廃液を収容するタンク

る。The present invention provides a method for operating a developing device, which is provided with a tank for storing waste liquid from a photosensitive material processing tank, the tank having a liquid level sensor for detecting a liquid level that is lower than a full liquid level by a predetermined liquid level. The predetermined amount of liquid is equal to or greater than the amount of waste liquid discharged until the photosensitive material being processed is sent out from the developing device, and when the liquid level is detected, the photosensitive material is supplied to the developing device. It is characterized by stopping.
このため本発明では、廃液が液面センサに達すると警報
が発せられるが、さらに廃液は満タン液位となるまで現

像装置の運転が停止される。For this reason, in the present invention, although an alarm is issued when the waste liquid reaches the liquid level sensor, the development process can be continued until the waste liquid reaches a full liquid level. When this full liquid level is reached, the operation of the developing device is stopped.
この運転停止は制御装置が液面センサからの信号を受け
た後に一例として所定時間経過して現像装置を停止させ

響を与えたり、廃液タンクから廃液が溢れ出る不具合は
ない。In this operation stop, for example, the developing device is stopped after a predetermined period of time has elapsed after the control device receives a signal from the liquid level sensor. However, all of the photosensitive material being developed in the developing device is discharged from the time the liquid level sensor is detected until the developing device is stopped, which may have an adverse effect on the photosensitive material being developed, or waste liquid from the waste tank. There is no problem with overflowing.

像不良を生ずることはない。If the waste liquid tank 48 is not replaced in the unit, the operation of the developing device 10 is continued. However, the control device 36 operates the cutter 34 to prevent the photographic paper P located upstream of the cutter 34 from entering the developing device 10. Thereafter, the control device 36 controls the developing device 10 after a predetermined period of time has elapsed.
It is determined that the waste liquid has risen from the liquid level L to the liquid level H with the operation of the developing device 10, and the operation of the developing device 10 is stopped. However, at this point, all of the photographic paper P with the part cut by the cutter 34 on the most upstream side has been taken out from the developing device IO, and even if the developing device 10 is stopped, the developing device 10
There is no photographic paper P inside. Therefore, when the developing device 10 is stopped, there is no possibility of developing defects due to the presence of photographic paper P inside the developing device 10.
なお補充タンク４２、廃液タンク４８は現像装置１０の
みでなく現像槽１２等の他の処理槽にも同様に設けられ
て同様の制御が行われている。Note that the replenishment tank 42 and the waste liquid tank 48 are provided not only in the developing device 10 but also in other processing tanks such as the developing tank 12, and are similarly controlled.
廃液タンク４８が新規な廃液タンク４８と交換されると
現像装置１０の運転が可能となりカッタ３４よりも上流
