PROBLEM TO BE SOLVED: To provide a coin-operated rice polishing machine that prevents additional feeding of unsuitable grains or erroneous feeding, etc., during rice polishing operation and that makes it easy for a user to charge unpolished rice into an unpolished rice hopper. SOLUTION: A feeding shutter (33) which can be moved up and down with an unpolished rice bag loaded and opens and closes an unpolished rice feeding port (2) is provided on the outer side of the unpolished rice feeding port (2) through which unpolished rice is charged into an unpolished rice hopper (1). By charging a fee through a coin slot (4), the feeding shutter (33) opens the unpolished rice feeding port (2) and moves to the position (33a) for placing the unpolished rice bag, and when the unpolished rice is charged into the unpolished rice hopper (1) to start rice polishing operation by turning on a switch (5) for rice polishing selection, the feeding shutter (33) is moved to a position (33c) for closing the unpolished rice feeding port (2).
