される。2. Description of the Related Art Since the processing performance of a processing solution in a photosensitive material processing apparatus is deteriorated as the photosensitive material is processed, a method of supplying a replenishing solution is used in order to maintain stable processing without lowering the processing performance. Has been done. As a method of supplying the replenisher, there is also a method of supplying the replenisher with the same concentration as the treatment solution, but it has the disadvantage of requiring a large storage space for the replenisher and has the disadvantage of easily degrading during storage. It is advantageous to supply a replenisher of a concentrated concentrate.
The concentrated liquid is mixed with dilution water and used as a processing liquid in a processing tank.

水の供給とは、それぞれ安定して定量給送するポンプを
もって行っているが、希釈水の給送については安定して
給送出来ない問題がある。If the mixing ratio with the diluting liquid is not maintained correctly, the processing performance will change. Therefore, the supply of the replenishing liquid and the supply of the diluting water are carried out by the pumps for stably and quantitatively supplying each of them. There is a problem that the dilution water cannot be stably fed.

て、処理の不安定又は、処理ムラの問題が発生する。Tap water can be used as the diluting water, and in many cases, a system in which the water temporarily stored in the supply tank is supplied to the treatment tank by a pump is used, but the tap water is injected into the water supply tank. In this case, a large amount of bubbles are generated in the water due to the drop from the water supply port of the water supply to the surface of the water in the water supply tank, and when the water supply pump sucks the bubbles, the amount of water supply becomes unstable. Therefore, the mixing ratio with the concentrated liquid changes, and as a result, the problem of unstable processing or uneven processing occurs.

ところで注水を停止する制御で容易に達成される。In the present invention, the partition plate is provided in the water supply tank, because when the water is supplied from the water supply means, bubbles are mixed into the water in the supply tank, and the bubbles supply water to the treatment tank. This is to prevent the water from being stably fed into the suction means of, and paying attention to the fact that air bubbles exist near the water surface, and when air bubbles move laterally, they are drawn into the suction port. In consideration of easy operation, a partition plate is provided in the vicinity of where bubbles are generated so as to project from the water surface above the water surface to prevent lateral movement of the bubbles. The reason why the upper end of the partition plate is higher than the maximum water level is that air bubbles do not get over the partition plate due to excessive water injection, and the maximum water level is managed by installing a water tank upper limit detection sensor, and the water level reaches the upper limit. It can be easily achieved by controlling the pouring of water at a certain point.

のが好ましい。The reason why the upper end of the flow channel of the partition plate is configured to be lower than the minimum water level is to prevent bubbles from moving laterally through the flow channel. When the minimum water level is reached, water injection is started. As a result, bubbles are generated on the water surface at the lowest water level, and if they can easily pass through the running water channel, the bubbles will move laterally and be sucked by the suction means. As a means for preventing this, it is preferable that the upper end of the flowing water channel is lower than the lowest water surface level, and the flow rate is sufficiently secured to be set as low as the structure allows.
【００１０】なお、最低水面位の管理も液面検出センサ

易に達成される。The management of the minimum water level can be easily achieved by providing a liquid level detection sensor and starting the water injection when the lower limit is reached.
