COIN-SHAPED MEMBER FEEDER

PROBLEM TO BE SOLVED: To provide techniques that are suitable for securing of detection accuracy for coin-shaped members and cost reduction and employ an automatic cleaning system by coin-shaped members because of such a problem that when the coin-shaped members in a hopper are sent out by high-speed rotation of a feeding rotor and a feeding detection section detects the number of fed members, a plurality of detection sensors need to be arranged for countermeasures against mischief and it is difficult to secure detection precision and reduce the cost and such a problem that when an optical sensor comprising a light emission portion and a light reception portion is employed, a decrease in detection accuracy and a defection failure due to, especially, dirt are caused. SOLUTION: A feeding section is provided with a detection section which detects the coin-shaped members sent out from a storage section, one by one, through the rotation of the feeding rotor made of synthetic resin and passing therethrough, and the detection section is formed with a coin-shaped member passage communicating with a coin-shaped member passage of the feeding section, in a single holder storing a plurality of detection sensors in itself.
