Encyclopedia > Coin acceptor

A coin acceptor is a device that recognises coins. It is built into vending machines, arcade cabinets, etc. It performs its function by evaluating the coin based on its weight, size, and magnetism, and then sends an appropriate electrical signal via its output connection. The next step is generally performed by the coin changer.


Simple mechanical coin acceptors are relatively easy to cheat by using slugs and other coin-like materials that pass the rudimentary validation. Today, sophisticated electronic coin acceptors are in use in some places that, in addition to validating weight and size, also "look" at the deposited coin using optics and match the image to a pre-defined list.

Coin acceptor - Wikipedia, the free encyclopedia (249 words)
A coin acceptor, also known as a coin mechanism or coin mech, is a device that recognises coins.
Today, sophisticated electronic coin acceptors are in use in some places that, in addition to validating weight and size, also "look" at the deposited coin using optics and match the image to a pre-defined list.
Coin acceptors are modular, so a dirty acceptor can be replaced with a clean unit while it is being cleaned, preventing downtime.
Encoder/diverter unit for coin-operated machine - Patent 4650057 (3625 words)
The coin handling apparatus of the present invention is broadly denoted by the numeral 10 and includes a coin acceptor device 12 of conventional design and an improved encoder/diverter unit 14 pivotally coupled to coin acceptor device 12 near the lower margin 16 thereof.
If the coin is accepted, it then passes downwardly past and through a coin passage in unit 14 in which it is counted and is directed either into a hopper (not shown) or to a drop bucket (not shown).
In the alternative, for an acceptor device 12 usable with a different coin size and denomination, rod 34 is coupled to holes 33 in the outer ends of a pair of laterally projecting arms 35 integral with respective side walls 26 and 28.
