A Dispensing machine is a machine that dispenses items such as snacks, beverages, alcohol, cigarettes, lottery tickets to customers automatically, after the customer inserts currency or credit into the machine. The first modern vending machines were developed in England in the early 19th century and dispensed postcards.
The earliest known reference to a dispensing machine is in the work of Hero of Alexandria, a first-century AD Greek engineer and mathematician. His machine accepted a coin and then dispensed holy water. When the coin was deposited, it fell upon a pan attached to a lever. The lever opened a valve which let some water flow out. The pan continued to tilt with the weight of the coin until it fell off, at which point a counterweight snapped the lever up and turned off the valve.
