  • Coin operated prize dispensing projecting game
    Patent number: 4487414
    Abstract: A slot machine or coin operated prize dispensing apparatus comprising a vertical gambling panel which forms a plane of movement for coins or similar flat, rolling tokens and which is provided with a plurality of prize sensors located in the plane of movement, a projector adjacent the plane of movement, a stake inserting slot, and a pay-out mechanism. A closed circulating path for projected coins is formed in the plane of movement of the gambling panel and passes adjacent the projector. The stake inserting slot is connected past the gambling panel to the pay-out panel by means of a separate circulating path for stake coins. Thus, the projected coins are independent of the number, value and combination of the stake coins so that the game can be priced and the prize relation changed without touching the projected coins.
