G-<strong>18.mft</strong> with vending machine control system DESIGN<br />
Return lever<br />
Coins inserted into <strong>the</strong> coin validator pass through <strong>the</strong> coin insert funnel 2<br />
into <strong>the</strong> measurement and validation area <strong>of</strong> <strong>the</strong> device, where <strong>the</strong>ir coin<br />
properties are compared with <strong>the</strong> values <strong>of</strong> <strong>the</strong> stored acceptance bands.<br />
Coins rejected by <strong>the</strong> coin validator are directed into <strong>the</strong> return area and<br />
coins accepted for <strong>the</strong> vending operation leave <strong>the</strong> device through <strong>the</strong> coin<br />
outlet 9, which is located at a fixed position because <strong>the</strong> coin validator does<br />
not have a sorting function. (See Fig. 1a)<br />
The return lever 1 on <strong>the</strong> top <strong>of</strong> <strong>the</strong> coin validator is ei<strong>the</strong>r directly operated<br />
mechanically or motor-controlled using <strong>the</strong> return button on <strong>the</strong> vending<br />
machine, if <strong>the</strong> coins which have already been inserted are to be returned<br />
or a jam caused by coins, e.g., which have become stuck needs to be<br />
removed. Operating <strong>the</strong> return lever opens <strong>the</strong> measurement and validation<br />
area <strong>of</strong> <strong>the</strong> coin validator so that all objects in <strong>the</strong> coin validator are<br />
transported into <strong>the</strong> return area. (See Fig. 1a)<br />
