Abstract: An ultrasonic sensor and method for using the same are arranged for capturing a value document transported through a capture region of the ultrasonic sensor. The ultrasonic sensor has an ultrasound transmitter arranged for emitting ultrasound into the capture region and an ultrasound receiver arranged for receiving ultrasound from the ultrasound transmitter from the capture region. A control and evaluation circuit is arranged for controlling the ultrasound transmitter and for capturing and evaluating the signals of the ultrasound receiver. A circuit carrier carries the control and evaluation circuit, the ultrasound transmitter, the ultrasound receiver, and conducting paths electrically connecting the control and evaluation circuit to the first and second ultrasonic transducers. The circuit carrier has a U-shaped configuration and two interconnected arm portions, and the ultrasound transmitter is held on one of the two arm portions and the ultrasound receiver on the other of the two arm portions.

Abstract: An apparatus for emitting and/or receiving ultrasound in a predetermined frequency range includes at least one ultrasonic converter for converting ultrasound into electrical signals and/or converting electrical signals into ultrasound, and a holder having at least one ultrasonic channel formed therein in which the ultrasonic converter is disposed at least partly and/or through which ultrasound can pass from or to the ultrasonic converter. The holder has at least one non-fibrous surface layer adjacent to at least one portion of the ultrasonic channel, whose impedance is smaller than that of an inside layer of the holder neighboring to the surface layer.

Abstract: An ultrasonic transducer module for an ultrasonic sensor for detection and/or examination of value documents which includes at least one piezoelectric ultrasonic transducer with electrical connecting strands, and a mounting module for holding the ultrasonic transducer for mounting on a connection support. The mounting module has conducting paths which are electrically connected to the connecting strands of the ultrasonic transducer and which have contact areas which are so configured that the ultrasonic transducer module is placeable for mounting onto a surface of the connection support on which there are located contact areas complementary to the conducting path contact areas, with the contact areas and the complementary contact areas being solderable to each other.

Abstract: The present invention relates to an apparatus for processing documents of value having a sensor device for checking the documents of value and a transport device by means of which the documents of value are transported along a transport direction past the sensor device. On a side opposing the sensor device there is disposed a guide element for passively guiding the document of value, which is moved as soon as several documents of value are transported at the same time past the sensor device. By the guide element according to the invention, documents of value can be reliably and accurately checked without great effort.

Abstract: A value-document processing apparatus for documents of value, such as, e.g. bank notes, checks, etc. having a transport system and one or more sensors. The sensors have a sensor surface past which the bank notes are transported, where the sensor surface is provided with a plurality of elevations or depressions. Through the structured surface, the friction is decreased between the sensor surface and the transported document of value, so that the transport of the document of value is stabilized and the proneness to jamming is reduced.

Abstract: A sensor for examining a document of value in a detection range of the sensor has at least one electrical component for converting electrical energy into sound waves and/or electromagnetic fields, in particular optical radiation, for examining the document of value and/or for detecting sound waves and/or magnetic or electromagnetic fields, in particular optical radiation, from the document of value to generate detection signals. Additionally, the sensor has a holder for the component, having a recess or a hole for at least partially accommodating the component, in which the electrical component is held, and on or in which at least one conductive path extends to contact with at least one electrical contact of the electrical component.

Abstract: In value-document processing apparatus documents of value, such as e. g. bank notes, checks, etc. are conveyed by a transport system along one or more sensors. The bank notes guided past the sensors touch the sensor surface at least temporarily. To improve the transport the sensor surface past which the bank notes are transported is provided with a plurality of elevations or depressions. Through the structured surface the friction is decreased between the sensor surface and the document of value transported past, so that the transport of the document of value is stabilized and the proneness to jamming is reduced.

The holder has at least one non-fibrous surface layer adjacent to at least one portion of the ultrasonic channel, whose impedance is smaller than that of an inside layer of the holder neighboring to the surface layer.
