At the same time, high-pressure solvent is injected against the inner wall of the coating container through the micropores. As a result, the sprayed solvent reaches all parts of the coating container, and due to the dissolving power of the solvent and the physical force of the high-pressure spray, the interior of the coating container is cleaned in a short time using a small amount of solvent. Additionally, the solvent used for cleaning accumulates at the bottom of the coating container. The used solvent is discharged from the bottom vibrator to clean it.

When the entire cylindrical substrate 1 is immersed, the overflowing photosensitive solution is received by the saucer 3 and returned to a stirring layer (not shown) by the return vibrator 4, where it is mixed with a solvent and adjusted. A vibrator 5 at the bottom of the coating tank 2 is used for draining old liquid and replenishing new liquid.

。The high-pressure cleaning device 1 includes a solvent tank 12 containing a solvent 11;
Vibrator 14, high pressure pump 13, injection nozzle 15, lid 17
It is composed of etc. The injection nozzle 15 is spherical and has a large number of microholes 16 formed on its surface. The one used in this example has a hole diameter of 178 inches and a pressure of 5
It was set as 0 kg/-. The cleaning solvent should be one that has properties such as high solubility in the coating liquid, easy handling, and low toxicity, and whether it is a single solvent or a mixed solvent, it is also used in the coating liquid. There is no problem even if it is a solvent. Although the photosensitive liquid 6 has been removed from the coating tank 2 in advance, the coating liquid still adheres to the inner wall of the coating tank. Moreover, the injection nozzle 15 has a mechanism that rotates depending on the injection pressure, and sprays the liquid evenly inside the coating tank 2, so that there are no blind spots. Every part is physically cleaned by the sprayed solvent, and combined with the chemical power of the solvent, the cleaning effect is improved in a short time.

めることができる。During cleaning, the coating tank 2 is covered with a lid 17 as shown in the figure, so that the cleaning agent is prevented from scattering, so the area around the coating tank is not contaminated, and the evaporation and diffusion of the solvent is also prevented. Furthermore, the solvent sprayed from the spray nozzle is reflected on the lid 2, thereby enhancing the cleaning effect.
洗浄を終了した溶剤１１は塗工槽２の底部に溜まり１１
’をバイブ４．５から排出させる。これにより、排出し
ながらバイブの洗浄を行うことができる。After cleaning, the solvent 11 accumulates at the bottom of the coating tank 2.

Therefore, the j-tsu is short-lived and requires no manpower.
It is possible to achieve a significant improvement in economic efficiency. .
