A coin checking device for a vending machine capable of electrically examining whether an inserted coin is a true coin or a counterfeit one as well as kind of the coin. The device detects a waveform representing passage of the coin and also whether the peak level of the waveform appears in a predetermined window or not and, if the peak level is detected in the window, judges that the inserted coin is a true one.

Coin checking device for a vending machine

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.
