Abstract
A coin identification device includes: a first magnetic sensor detecting an amount of magnetic variation while the coin passes in the carrying direction; a second magnetic sensor installed where the second magnetic sensor detects a passage of an arc of a small-diameter coin when the first magnetic sensor detects a passage of the small-diameter coin; and a third magnetic sensor installed where the third magnetic sensor does not detect a passage of an arc of the small-diameter coin when the first magnetic sensor and the second magnetic sensor detect a passage of the small-diameter coin and detects a passage of an arc of a large-diameter coin; and an identification control unit identifying an outer diameter of the small-diameter coin and the large-diameter coin based on the amount of magnetic variation of the first magnetic sensor.
