Abstract:
PCT No. PCT/AU91/00295 Sec. 371 Date Feb. 22, 1993 Sec. 102(e) Date Feb. 22, 1993 PCT Filed Jul. 4, 1991 PCT Pub. No. WO92/01270 PCT Pub. Date Jan. 23, 1992.A coin validator (10) has a coin path (26) which passes between one set of detect coils (40, 42). The set of coils (40, 42) is connected in a detect circuit, and the coils (40, 42) are adapted to be energized with a single pulse. The decay curve (70) of the voltage in the coils (40, 42) is processed to produce a set of three numbers of clock counts defining each coin, which are stored in a microprocessor. Preprogramming of the validator (10) involves generating sets of numbers for representatives of a coin type to create three ranges of numbers, within which respective range a subsequent coin's set of numbers must fall in order for it to be defined as an example of the coin type. The coin path (26) is arranged at an angle to the vertical, and the base (32) is arranged at an angle to the horizontal such that the angle between one wall (36) and the base (32) is between 90 DEG and 180 DEG , causing coins passing along the coin path (26) to orient themselves such that each of them has point contact on the base (32) and on one wall (36), thereby occupying a generally similar position with respect to the coils (40, 42).
