Abstract

PURPOSE:To realize the labor saving for operation of a cleaning device, by securing an automatic counting of the number of sponge balls with use of plural photoelectric tubes and thus avoiding counting the foreign matters if detected as the number of sponge balls. CONSTITUTION:When a sponge ball passes through a transparent casing 11, a light source 12 has parallel beams by a lens 13 and cuts off the luminous flux that transmits through a mask 18 and the casing 11 to reach a photoelectric tube 15. Thus the current value of the tube 15 is reduced. The number of sponge balls can be counted accurately although a foreign matter 20 different from the sponge ball into a tube. Thus plural tubes, i.e., two tubes 15 are used, and accordingly reduction of current value same as that caused when a sponge ball passes through, if occurred, shows a small value on a display device 19a even in case a substance 20 passes through within the casing 11. Then display devices 19a and 19b are connected with an AND circuit to give distinction between a sponge ball and foreign substance.
