ABSTRACT:
A stored coin and bill number counter unit counts up the numbers of deposited coins and bills for respective denominations and counts down the numbers of paid out coins and bills for the respective denominations and thereby obtains the numbers of coins and bills for the respective denominations stored for paying out of change. A comparison and operation unit primarily judges whether vending is possible or not by comparing the amount of the deposited coins and bills with the set vend price and obtains the amount to be paid out as change by calculating difference between the deposited amount and the set vend price. A change payout permission judgement unit judges whether payout of the amount to be paid out as change is possible or not by utilizing the numbers of the coins and bills of the respective denominations calculated by the counter unit and, if such payout is possible, permits ultimately vending of an article corresponding to the set vend price on condition that the comparison unit has judged, with respect to the particular set vend price, that vending is possible. A shortage detection device may be provided in association with a change coin and bill storage device for detecting whether or not there is shortage of stored coins and bills of the respective denominations and the judgement unit may make the above described judgement on the basis of outputs of both the shortage detection device and the counter unit.
