METHOD AND APPARATUS FOR CLEANING DRUM SUBSTRATE FOR PHOTOSENSOR

摘要

PROBLEM TO BE SOLVED: To enable scrub cleaning to be simply and efficiently carried out with a cleaning brush in a cleaning liquid flowing through a drum substrate. SOLUTION: A drum substrate 4 is placed horizontally on and in parallel with a support roller 20 and a cleaning brush 21 horizontally arranged in parallel with each other in a cleaning vessel 3. While a cleaning liquid 2 is caused to horizontally flow into the cleaning vessel 3, the support roller 20 and the cleaning brush 21 are rotated in the same direction to rotate the drum substrate 4 at a speed different from that of the cleaning brush. Thus, the drum substrate 4 in the state of being immersed in the flowing cleaning liquid 2 is subjected to scrub cleaning with the cleaning brush 21.
