Abstract
A toy bank having a coin discriminating mechanism for discriminating between coins of varying diameters. The mechanism includes a housing having a coin slot, the slot having two generally flat, spaced walls and two relatively narrow spaced sides, the sides defining the breadth of a coin passageway. A movable slide is disposed within the passageway and normally biased toward a resting position at least partially obstructing the breadth of the passageway. The slide is movable in response to insertion of a coin. Electronic circuitry is provided to detect movement of the slide and translate that movement into information relating to the denomination of the coin. Preferably the slide is movable in a direction not parallel to a line defined by a first point of contact between a coin and the slide, and a second point of contact between the coin and the first side of the passageway, said points of contact being identified when the slide is maximally displaced by the coin. In this configuration, the differences in displacement of the slide upon insertion of coins of varying diameters will be larger than the differences in the diameters of the respective coins.
