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.

Figure 00000001
Coin operated device with a device for determining the hardness of coins, with a sensor containing a piezoelectric element, which has a relatively hard stop surface in relation to the coin material, against which the coins strike, and evaluation electronics, which evaluate the vibration behavior of the piezo element due to the impact with the coins and compares it with predetermined values, the sensor being arranged resiliently so that when a coin hits the abutment surface for the first time, further impacts follow and the evaluation electronics evaluate the vibrations caused by the multiple impacts.
