PROBLEM TO BE SOLVED: To solve the problem that the number of times of lever depression is forgotten by mistake during the lever operation since the lever needs to be depressed e.g. four times in the case of measuring/dispensing four cups of rice, for most of rice dispensers. SOLUTION: By depressing a lever 39 to turn a rack 41 counterclockwise for measuring rice K, the pressing piece 55 of a limit switch 53 is pressed by the upper surface of the rack 41 to press a button. Then, an electric signal from a limit switch 53 is transmitted to an LED control circuit to light an LED 49a, indicating that the rice is measured once. When depressing the lever 39 again, an LED 49b is lit similarly. Whenever the lever 39 is depressed, LEDs 49a, 49b, 49c and 49d are lit in order, thereby the number of times of having measured the rice is indicated. COPYRIGHT: (C)2004,JPO&NCIPI
