Abstract

Münzgerät mit einer Vorrichtung zur Härtebestimmung von Münzen, mit einem ein piezoelektrisches Element enthaltenden Sensor, der eine im Verhältnis zum Münzmaterial relativ harte Anschlagfläche aufweist, an der die Münzen anschlagen, und einer Auswerteelektronik, die das Schwingungsverhalten des Piezoelements aufgrund des Stoßes mit den Münzen auswertet und mit vorgegebenen Werten vergleicht, wobei der Sensor federnd so angeordnet ist, daß bei einem ersten Auftreffen einer Münze auf die Anschlagfläche weitere Stöße nachfolgen und die Auswerteelektronik die durch den Mehrfachstoß verursachten Schwingungen auswertet.
