A plurality of coin storage sections 12 ₁ to 12 ₄ on S ₁ and S ₂ respectively
and 13 ₁ to 13 ₄ are arranged respectively, so
It has a large number of coin accommodating parts and can accommodate a large number of different types of coins. The coin ejecting rod 23 is held by the coin ejecting rod holding member 22 and horizontally rotated by the rotating shaft 3, and its upright portions 26 and 27 rotate in the same circles as the circles S ₁ and S ₂ , respectively. In normal times, that is, when coins are not ejected, the solenoid 28 is not driven and the plunger rod 30 is lowered, so the coin ejecting rod 23 is pressed down by the return spring 25 and rotates horizontally while rotating downward. , the upright portions 26 and 27 correspond to each of the coin storage portions 12 ₁ to 12 ₄
The coin receiving portions 17 and 18 of 13 ₁ to 13 ₄ are located below and rotate. When coins are to be discharged, the coin discharge control section 55 drives the solenoid 28 based on the detection signals from the detectors 34 and 35. To explain this operation in detail, for example, when the amount of change is 100 yen, the coin discharge control section 55 drives the solenoid 28. sets the ejected coins as one 100 yen coin and one 10 yen coin, holds these in the register, and sends this ejected coin signal to the coin ejection control section 55. The coin ejecting control section 55 controls the solenoid 28 to raise the ejecting rod based on the ejecting coin signal from the ejecting coin specifying section 56 and the ejecting rod position signal from the ejecting rod position determination circuit 52, for example. When a signal of a 100 yen coin is sent from the ejected coin designating section 56, the upright portion 27 of the coin ejecting rod 23 moves into a coin storage tube (for example, the second coin storage tube 13 ₁ ) that accommodates a 100 yen coin. When the position signal is input from the ejecting rod position determination circuit 52, the solenoid 28 is excited and driven to raise the coin ejecting rod 23 to the coin ejecting height. When the coin passes through the coin storage tube and the position signal is input from the pushing rod position determination circuit 52, the excitation of the solenoid 28 is stopped and the coin pushing rod 23 is lowered by the spring force of the return spring 25, and at the same time Ejected coin designation section 5
A 100 yen coin ejection completion signal is sent to 6 to cause the number of 100 yen coins held in the register of the ejected coin designating section 56 to be subtracted by 1.
This is the same when discharging other types of coins, and in this coin discharging operation, the number of each coin held in the register of the discharged coin designating section 56 is all 0.
