The water injection nozzle 164 provided at the tip of each of the pipes 150A and 150B is narrowed by an orifice 166 with respect to the sectional area of the pipes 150A and 150B. Therefore, the water pressure in the pipes 150A and 150B rises, and water is jetted from the water injection nozzle 164 to the rinse tanks 28 and 30 according to the water pressure and the opening area of the orifice 166. At this time, since the water pressure in the pipes 150A and 150B is constant, the same amount of water is ejected and supplied to the rinsing tanks 28 and 30.

That is, the same amount of water is supplied to the rinsing tanks 28 and 30 irrespective of the difference in the flow path resistance between the pipes 150A and 150B due to different pipe paths and pipe lengths. be able to. If the opening area of the orifice 166 of the rinsing tank 28 and the orifice 166 of the rinsing tank 30 are changed, the amount of water supply can be changed according to the opening area.

When the operation of the water supply pump 154 is stopped,
Since the opening area of the tip of the water injection nozzle 164 is adjusted by the orifice 166, the piping 150A, 150B
The water inside does not flow out.

When the water supply pump 154 is stopped, the water pressures in the pipes 150A and 150B are the same.
Next, when the water supply pump 154 is operated, the branch portion 150C
The same amount of water can be supplied to the rinsing tanks 28 and 30 without losing the balance of the water flowing into the pipes 150A and 150B.

As described above, even if the piping for supplying water from the water supply tank 144 to the two rinse tanks 28 and 30 by one water supply pump 154 is simplified, water can be supplied to the rinse tanks 28 and 30 with good balance. The water supply pump 154 can supply water to two or more rinsing tanks. By narrowing the water supply port of each of the branched rinsing tanks with an orifice 166, the rinsing tanks are well balanced. It is possible to supply water.
