Abstract: Apparatus for automatic feed of change coins in a coin operated machine comprising a storage section for change coins including a cylinder for the change coins, a discharge section for discharging coins stored in the cylinder into a guide section which in turn supplies the coins to a second cylinder in which the coins are stored for distribution as change when instructed by a coin selection control device. Such control device includes a drive motor which operates the discharge section under the control of a switch which is operated when the coins in the second cylinder reach a pre-determined minimum amount.

Abstract: A vending machine adapted to temporarily retain a coin of large denomination which is not usable as a change coin among the deposited coins and store coins of small denominations in coin stacking tubes. When the deposited money is to be returned, coins of the same denominations as the deposited small denomination coins are paid out from the coin stacking tubes while the retained large denomination coin itself is also returned. In event the vending machine is short of change coins, the vending machine vends the required article only when a coin requiring no change is deposited and automatically returns the deposited coin when a coin requiring change is deposited.
