The present invention is directed to a coin detection apparatus that is specially designed to avoid coins' sticking in a coin passage and that is capable of distributing an item to a customer only when a predetermined number of valid coins are paid. Coins (C) deposited by the customer are kept in a coin shoot ( 13 ). The coins (C) stand upright on a floor plate ( 20 ) that forms a part of the coin shoot ( 13 ). The floor plate ( 20 ) is urged by a spring member to protrude into the coin shoot ( 13 ). As a rotary disk ( 100 ) rotates, one end ( 119 ) of a recessed portion ( 120 ) defined in the rotary disk ( 100 ) leans on the floor plate ( 20 ) against elastic force of the spring member to make the floor plate ( 20 ) tilt. Subsequently, recessed edge of the rotary disk ( 100 ) continues to tilt the floor plate ( 20 ). As the other end 118 of the recessed portion ( 120 ) reaches the floor plate ( 20 ), the floor plate ( 20 ) is disengaged from the rotary disk ( 100 ). Tilt of the floor plate ( 20 ) causes the coins (C) to be evacuated from the floor plate ( 20 ), and the coins fall direction into a coin drop.
