When coin payout is performed by the forward rotation of a coin payout motor (40), a coin payout controller (80) detects the occurrence of a coin jam from the operational circumstances of a carrier switch (60) up to the time when a first timer (81) runs out, and determines whether the reverse rotation of the coin payout motor (40) would cause a problem based on the current state of the carrier switch (60), so that the coin payout motor (40) is reversed and the coin jam dislodged only when no problem will be caused.
