PROBLEM TO BE SOLVED: To provide a coin-operated rice polishing apparatus that can prevent residual grain brought thereinto by a user and having been subjected to a rice polishing treatment, from mixing with grain to be brought thereinto by a subsequent user. SOLUTION: The coin-operated rice polishing apparatus that causes a rice polisher (8) to polish grain fed into a feed hopper (1) includes a controller (S) that carries out a cleaning process of transferring residual grain present in the feed hopper (1) to a storage box (28) by driving a grain delivery device (11) disposed at the bottom of the feed hopper (1) subsequent to the completion of the rice polishing operation.
