Various signals are exchanged between a coin acceptor section that identifies the authenticity of deposited coins and sorts out the on the basis of their denominations, and a change control section that receives the sorted-out coins and performs control to count the coins and to deliver the coins as a change. Such a signal exchange between the two sections is achieved through optical coupling between a light emitting diode and a photo transistor, without employing any electric contacts. Further, electric power supply from the change control section to the coin acceptor section is done through spring-biased probes without employing any electric connectors, or through inductive coupling without employing any electric contacts. Such arrangements can greatly facilitate attachment and detachment of the coin acceptor section to and from the change control section.

Deposited coins are stored in a coin storing device and change is paid out of coins storred in this storing device. For detecting an amount of coins going in and out of the coin storing device, a going-in-and-out detector is provided. For setting an initial amount P of stored coins in the coin storing device, an initial stored coin amount setter is provided. In an operation device, an operation for obtaining difference N between a current amount S of stored coins and the initial amount P in accordance with the output of the going-in-and-out detector and the initial amount P. When the amount of stored coins in the coin storing device is to coincide with the initial amount P (e.g., when an inventory operation is to be performed), a command device commands this. In response to this command, a payout control device performs, if the current amount S is larger than the initial amount P, control for paying out the number of coins corresponding to the difference N. Thus, if the current amount S of stored coins is larger than the initial amount P, a superfluous coin is automatically paid out so that the amount of stored coins is caused to coincide with the initial amount P. Conversely, if the current amount S of stored coins in the coin storing device is smaller than the initial amount P, a display control device displays that the amount of stored coins is short. The operator may additionally deposit deficient coins upon finding the deficiency whereupon the amount of stored coins is caused to coincide with a predetermined initial stored coin amount P.

This bill validator accumulates bills between a pair of spaced parallel stationary members forming an entrance of a bill accumlating box and a bill compressing plate provided in the bill accumulating box. A push member is disposed in the vicinity of the entrance of the accumulating box. This push member is actuated by a reciprocating mechanism to push a bill positioned at the entrance into the accumulating box and thereby add this bill to a stack of accumulated bills. Constant springs are provided in association with the bill compressing plate. These constant springs enclose a bill accumulating space in the accumulating box with their winding shafts being pivotably connected on the accumulating box and their taken out ends being fixedly secured to the bill compressing plate. The constant springs urge the bill compressing plate to the entrance of the accumulating box with a constant pressing force. Since the pressing force of the constant springs can be made small regardless of a maximum possible number of bills to be accumulated, the driving force required for reciprocating the push member against this spring force can be made small.
