自動販賣機是誰發明的?

The first vending machine is believed to have been invented by Hero of Alexandria, a first-century inventor. His machine accepted a coin and then dispensed a fixed amount of holy water. When the coin was deposited, it fell upon a pan attached to a lever. The lever opened up 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 counter-weight would snap the lever back up and turn off the valve.

Note: Alexandria is actually a engineer and geometer.

自動販賣機是一部藉由鈔票智能測檢機 能與顧客交易的機器，能夠幫助顧客購買商品（與需要結帳人員的商店不同）。 第一個發明的人，一般相信是生於一世紀的亞歷山大港的希羅(Hero of Alexandria)，他製造的機器接受了硬幣後會給顧客一定數量的聖水。

好似係一個一世紀的亞歷山大港的希臘科學家生希羅(Hero of Alexandria)發明的
這本來是為教堂而設的,由容器入口投入硬幣后,機器會給顧客一定數量的聖水。
