PURPOSE: To completely and securely polish unpolished rice corresponding to coins by providing an unpolished rice tank with a supply detector and a rest detector for unpolished rice.
CONSTITUTION: The unpolished rice tank 4 is provided with the supply detector S1 which detects unpolished rice beginning to be supplied through the driving of a conveyance device, stops the conveyance device a specific time after the detection is started, and supplies a specific amount of unpolished rice corresponding to the given coins. Further, the unpolished rice tank is provided with the rest detector S2 which detects unpolished rice left in the tank 4 without being polished after certain-time operation and polishes the rice until no left unpolished rice is detected and an additional timer device which adds polishing rice for a necessary time after no unpolished rice is detected. Consequently, the unpolished rice is prevented from being left in the tank without being polished since the given coins do not match the amount of thrown-in unpolished rice.
