PROBLEM TO BE SOLVED: To provide a locking mechanism using a cylinder key, which enables a key plate to be pulled out from a keyhole in the state of preventing a locking member from being a hindrance to an operation when a medal supply door is opened. SOLUTION: In a state in which the medal supply door 6 is opened, a key cylinder 30 of the locking mechanism of the medal supply door 6 can be wholly turned to a second position 34B under a state in which the key plate 40 is kept extractable. The key cylinder 30 is turned to the second position 34B, so that the locking member 33 can form the state of not protruding to a medal supply port. This prevents the locking member 33 of the key cylinder 30 from being the hindrance to the operation in a state in which the medal supply door 6 is opened, and enables the key plate 40 to be pulled out from the keyhole 32 in the state.
