Patent GB-1589459-A (GB)
Title: Coin tester for rejecting coins falling below a minimum weight
IPC: G07D5/04
Filed: 1978-05-30
Abstract: The coin tester has a coin balance (1) with an arm (5) tiltable about a pivot axis (2) between a position of rest and a coin-accepting position. The arm (5) forms, at its end, an inclined rail (6) which serves as a running surface for the coins (M) and which has two portions (7, 8) of differing widths. A wall (3), which limits the path of the coins laterally, is arranged in such a way that the wider portion (7) always projects through it, but the narrower portion (8) projects through it only in the coin-accepting position of the arm (5). Coins which are too light cannot move the arm (5) out of its position of rest, roll only as far as the end of the wider portion (7) on the rail (6) and from there fall into the ejection channel (11). Coins reaching the necessary minimum weight press the arm (5) into its coin-accepting position and roll on the rail (6) as far as its end, where they pass into a further coin tester or into the till. This produces a coin tester which takes up only a little space and which guarantees virtually maintenance-free and fault-free operation.   <IMAGE>
