DEVICE AND METHOD FOR EXAMINING DOCUMENTS OF VALUE AND/OR TRANSPORTING DOCUMENTS OF VALUE BY MEANS OF ULTRASOUND

摘要

A description is given of a device for examining documents of value and/or transporting documents of value, which are transported along a predetermined transporting path in a predetermined transporting direction, by means of ultrasound, with ultrasound transmitters arranged offset in a direction transverse to the transporting direction for emitting ultrasound onto the transporting path in response to transmission signals and ultrasound receivers arranged offset in a direction transverse to the transporting direction for receiving ultrasound that is generated by means of the ultrasound transmitters and for emitting reception signals, wherein the ultrasound transmitters and/or ultrasound receivers each have at least one capacitive, micromechanical ultrasound transducer.
