Abstract

PURPOSE:To improve the coating efficiency of a photosensitive coating and to obtain uniform film thickness and a uniform coat surface with high productivity by spraying a coating from the horizintal direction to a photosensitive base board, blowing clean air from the vertically upper direction and exhausting the air from the lower part. CONSTITUTION:While being moved in parallel with its rotary shaft, a spray gun 11 executes spray scanning to the base board 10 from the borizontal direction. Clean air is previously and sufficiently carried into a spray hood 12 to remove dust adhered to the spray hood 12 and the base board 10 sufficiently. The arrangement of a blowing port 13 and an exhaust port 14 on the upper and lower positions respectively is effective for the removal of dust, and when the inside of the spray hood 12 is sufficiently cleaned, spray scanning is started. It is preferable to set up the direction of the rotation of the base board to the positive direction when the spray gun 11 is located on the 1st quadrant of the x-y plane defining the rotary axis of the base board as its original point, and to the negative direction when on the 2nd quadrant.
