Title:
Coin processing device
Document Type and Number:
Japanese Patent JP6352124
Kind Code:
B2
Abstract:
To improve detection accuracy of each outer diameter of plural types of coins. A coin processing device 1 including: a material detection sensor 4a which includes a first coil L1 and a second coil L2 facing each other with a coin passage 3 interposed therebetween; an outer diameter detection sensor 4b which includes a ring-shaped third coil L3 that surrounds the first coil and a ring-shaped fourth coil L4 that surrounds the second coil, the third coil and the fourth coil facing each other with the coin passage interposed therebetween; a first oscillation circuit 11 which is connected to the material detection sensor and oscillates a first oscillation signal in an individual connection state and is connected to the material detection sensor and the outer diameter detection sensor that are connected in series and oscillates the first oscillation signal in a series connection state; a second oscillation circuit 12 which is connected to the outer diameter detection sensor and oscillates a second oscillation signal in the individual connection state; a switching unit 15 which switches the individual connection state and the series connection state; and a coin identification unit 16 which detects an outer diameter of a coin using the second oscillation signal in the individual connection state or the first oscillation signal in the series connection state.
