Abstract

PROBLEM TO BE SOLVED: To quickly replace water in a water passage to quickly and surely perform an image processing by connecting a pump to, at least, one end side of the water passage, and providing a drain valve to open and close a drain path. SOLUTION: When a pump 28 is operated, external water is forcedly carried into a water passage 20, and the water in the water passage 20 is forcedly drained to the outside through a drain pipe 26, the pump 28 and a drain valve 30. When the pump 28 is then closed, the drain valve 30 is closed to keep the water within the water passage 20 in the stationary state. When the light from a light source device is introduced into an optical fiber cable 12 in this state, the light is emitted toward the water passage 20 through the lens part 8 of an image-pickup camera 4. Since the quantity of light is varied depending on the presence of microorganisms in the water passage 20, the light is reflected by a light reflecting plate 24, the image contrasted thereby is picked up by the body part 6 of the camera 4, and its image signal is guided to an image processing part followed by processing.
