tank, through said transparent member;
wherein said internal portion of said spray tank is
photographed by said camera to determine an existence of residual
bubbles in said spray tank.
10. A liquid spraying apparatus comprising:
a nozzle plate provided at a portion of a lower wall surface
of a spray tank which stores a liquid therein, the nozzle plate
having a row of nozzles made up of a plurality of nozzle holes
