Description

Ultraschallsensor zur Erfassung von Wertdokumenten und Verfahren zur Ultrasonic sensor for recording value documents and method for
Herstellung desselben Production of the same
Die vorliegende Erfindung betrifft einen Ultraschallsensor zur Erfassung eines durch einen Erfassungsbereich des Ultraschallsensors transportierten Wertdokuments sowie ein Verfahren zur Herstellung eines solchen Ultraschallsensors. The present invention relates to an ultrasonic sensor for detecting a value document transported by a detection range of the ultrasonic sensor and a method for manufacturing such an ultrasonic sensor.
Unter Wertdokumenten werden dabei blattförmige Gegenstände verstanden, die beispielsweise einen monetären Wert oder eine Berechtigung repräsentieren und daher nicht beliebig durch Unbefugte herstellbar sein sollen. Sie weisen daher nicht einfach herzustellende, insbesondere zu kopierende Merkmale auf, deren Vorhandsein ein Indiz für die Echtheit, d.h. die Herstellung durch eine dazu befugten Stelle, ist. Wichtige Beispiele für solche Wertdokumente sind Chipkarten, Coupons, Gutscheine, Schecks und insbesondere Banknoten. Ultraschallsensoren der oben genannten Art können auf wenigstens zwei verschiedene Einsatzzwecke hin ausgebildet sein. Zum einen können sie zur ortsaufgelösten Erfassung von Ultraschalleigenschaften eines Wertdokuments ausgebildet sein; zum anderen aber zur Transportüberwachung, beispielsweise der Erkennung der Anwesenheit eines Wertdokuments in dem Erfassungsbereich und/ oder des Eintreffens einer in Transportrichtung gesehen vorderen oder hinteren Kante des Wertdokuments, ausgebildet sein. Under value documents are understood leaf-shaped objects that represent, for example, a monetary value or an authorization and therefore should not be arbitrarily produced by unauthorized persons. They therefore have features which are not easy to manufacture, in particular to be copied, whose presence is an indication of the authenticity, i. the manufacture by an authorized agency. Important examples of such value documents are chip cards, coupons, vouchers, checks and in particular banknotes. Ultrasonic sensors of the above type may be designed for at least two different purposes. On the one hand, they can be designed for the spatially resolved detection of ultrasonic properties of a value document; on the other hand, however, for transport monitoring, for example the detection of the presence of a value document in the detection area and / or the arrival of a front or rear edge of the value document viewed in the transport direction.
Bei einer typischen Anordnung stehen sich ein Ultraschallwandler, der Ultraschall abgibt und ein Ultraschallwandler, der Ultraschall empfängt ge- genüber. Diese bilden eine Ultraschallstrecke zwischen sich. In a typical arrangement, there is an ultrasonic transducer that emits ultrasound and an ultrasonic transducer that receives ultrasound. These form an ultrasound path between them.
Die Herstellung solcher Ultraschallsensoren und auch die Montage an bzw. in einer Wertdokumentbearbeitungseinrichtung ist mit einigem Aufwand verbunden, da die Ultraschallwandler aufeinander ausgerichtet befestigt und deren elektrische Anschlüsse mit Ansteuer- und Auswerteschaltungen verbunden werden müssen. Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Ultraschallsensor zur Erfassung eines durch einen Erfassungsbereich des Ultraschallsensors transportierten Wertdokuments bereitzustellen, der eine einfache Herstellung ermöglicht. Weiter soll ein Verfahrens zu dessen Herstellung angegeben werden. The production of such ultrasonic sensors and also the mounting on or in a value document processing device is with some effort connected, since the ultrasonic transducers mounted aligned with each other and their electrical connections must be connected to control and evaluation circuits. It is therefore an object of the present invention to provide an ultrasonic sensor for detecting a value document transported by a detection area of the ultrasonic sensor, which enables simple production. Furthermore, a method for its production should be specified.
Die Aufgabe wird gelöst durch einen Ultraschallsensor zur Erfassung eines Wertdokuments, das durch einen Erfassungsbereich des Ultraschallsensors transportiert wird, mit einem Ultraschallsender und einem Ultraschallempfänger, die so angeordnet sind, daß Ultraschall von dem Ultraschallsender in den Erfassungsbereich abgebbar ist und aus dem Erfassungsbereich kommender Ultraschall des Ultraschallsenders von dem Ultraschallempfänger empfangbar ist, mit einer Ansteuer- und Auswerteschaltung zur Ansteue- rung des Ultraschallsenders und zur Erfassung und Auswertung von Signalen des Ultraschallempfängers und einem Schaltungsträger, an dem die An- Steuer- und Auswerteschaltung, der Ultraschallsender und der Ultraschallempfänger sowie die Ansteuer- und Auswerteschaltung mit dem ersten und zweiten Ultraschallwandler elektrisch verbindende Leiterbahnen gehalten sind, wobei der Schaltungsträger U-förmig ausgebildet ist und zwei miteinander verbundene Schenkelabschnitte aufweist, und wobei der Ultraschall- sender an einen der zwei Schenkelabschnitte und der Ultraschallempfänger an dem anderen der zwei Schenkelabschnitte gehalten ist The object is achieved by an ultrasonic sensor for detecting a value document, which is transported through a detection range of the ultrasonic sensor, with an ultrasonic transmitter and an ultrasonic receiver, which are arranged so that ultrasound can be emitted from the ultrasonic transmitter in the detection area and coming out of the detection range of the ultrasound Ultrasonic transmitter of the ultrasonic receiver is receivable, with a control and evaluation circuit for controlling the ultrasonic transmitter and for detecting and evaluating signals of the ultrasonic receiver and a circuit carrier to which the on-control and evaluation, the ultrasonic transmitter and the ultrasonic receiver and the drive - And evaluation circuit with the first and second ultrasonic transducers electrically connecting conductor tracks are held, wherein the circuit carrier is U-shaped and has two leg portions connected to each other, and wherein the ultrasonic transmitter is held on one of the two leg sections and the ultrasonic receiver is held on the other of the two leg sections
Die Aufgabe wird weiter gelöst durch ein Verfahren zur Herstellung eines Ultraschallsensor, insbesondere eines erfindungsgemäßen Ultraschallsen- sors, bei dem ein U-förmiger Schaltungsträger, der zwei miteinander verbundene Schenkelabschnitte und auf dem Schaltungsträger ausgebildeten Leiterbahnen aufweist, hergestellt wird, ein Ultraschallsender und ein Ultraschallwandler unter Herstellung einer elektrischen Verbindung mit zum An- schluß der Ultraschallwandler vorgesehenen Leiterbahnen mit dem U-förmigen Schaltungsträger so verbunden werden, daß der Ultraschallsender an einem der zwei Schenkelabschnitte und der Ultraschallempfänger an dem anderen der zwei Schenkelabschnitte gehalten ist und daß Ultraschall von dem Ultraschallsender in den Erfassungsbereich abgebbar ist und aus dem Erfassungsbereich kommender Ultraschall des Ultraschallsenders von dem Ultraschallempfänger empfangbar ist. The object is further achieved by a method for producing an ultrasonic sensor, in particular an ultrasonic transmitter according to the invention. An ultrasound transmitter and an ultrasound transducer are produced to produce an electrical connection with interconnects provided for connection of the ultrasound transducers to the U-shaped circuit carrier Circuit substrate are connected so that the ultrasonic transmitter is held on one of the two leg portions and the ultrasonic receiver on the other of the two leg portions and that ultrasound from the ultrasonic transmitter in the detection range can be issued and coming out of the detection range of the ultrasound ultrasonic transmitter is receivable by the ultrasonic receiver.
Der Ultraschallsensor verfügt über den U-förmigen Schaltungsträger mit den beiden Schenkelabschnitten, zwischen denen hindurch ein Wertdokument zur Erfassung durch den Ultraschallsensor, genauer den an dem einen Schenkelabschnitt gehaltenen Ultraschallsender und den an dem anderen Schenkelabschnitt gehaltenen Ultraschallempfänger wenigstens teilweise hindurchtransportierbar ist. Der Ultraschallsender und der Ultraschallempfänger bilden somit eine Ultraschallstrecke, entlang derer Ultraschall von dem Ultraschallsender abgegeben und - bei Abwesenheit eines Wertdokuments - direkt zu dem Ultraschallempfänger gelangen kann. The ultrasound sensor has the U-shaped circuit carrier with the two leg sections, between which a document of value for detection by the ultrasound sensor, more precisely the ultrasound transmitter held on the one leg section and the ultrasound receiver held on the other leg section is at least partially transportable therethrough. The ultrasound transmitter and the ultrasound receiver thus form an ultrasound path along which ultrasound can be emitted by the ultrasound transmitter and - in the absence of a value document - can reach the ultrasound receiver directly.
Der Schaltungsträger kann, bis auf dessen U-förmige Ausbildung, prinzipiell beliebig ausgebildet sein. Vorzugsweise wird als Schaltungsträger eine U- förmige Leiterplatte verwendet. Es wäre aber auch denkbar, falls notwendig, Schaltungsträger zu verwenden, die nicht plattenförmig ausgebildet sind. Beispielsweise könnten die Schenkelabschnitte auch einen rechteckigen, insbesondere quadratischen, oder einen runden Querschnitt in einer Schnittebene quer zur Längsrichtung der Schenkelabschnitte aufweisen. Auf dem Schaltungsträger ist auch vorzugsweise die Ansteuer- und Auswerteschaltung gehalten, die zur Ansteuerung des Ultraschallsenders und zur Auswertung der Signale des Ultraschallempfängers ausgebildet ist. The circuit carrier can, except for the U-shaped design, in principle be formed arbitrarily. Preferably, a U-shaped printed circuit board is used as circuit carrier. It would also be conceivable, if necessary, to use circuit carriers which are not plate-shaped. For example, the leg sections could also have a rectangular, in particular square, or a round cross-section in a sectional plane transverse to the longitudinal direction of the leg sections. On the circuit carrier and the control and evaluation circuit is preferably also held, which is designed for controlling the ultrasonic transmitter and for evaluating the signals of the ultrasonic receiver.
Der erfindungsgemäße Ultraschallsensor zeichnet sich daher insbesondere dadurch aus, daß sowohl Ultraschallsender als auch Ultraschallempfänger auf demselben, damit also nur einem, Schaltungsträger gehalten sind, der gleichzeitig die elektrische Kontaktierung von Ultraschallsender und Ultra- schallempfänger ermöglicht. Es ist daher nicht notwendig, Ultraschallsender und -empfänger separat in ein Gehäuse einzubauen, aufeinander ausrichten und dann noch zu kontaktieren. Die Herstellung des erfindungsgemäßen Ultraschallwandlers wird so erheblich vereinfacht Die Baugruppe mit dem Schaltungsträger und darauf angeordnet dem Ultraschallsender, dem Ultraschallempfänger und auch der Ansteuer- und Auswerteschaltung kann einfach als Ganze gehandhabt werden. Insbesondere kann der U-förmige Schaltungsträger mit dem darauf gehaltenen Ultraschallsender und dem darauf gehaltenen Ultraschallempfänger in ein Sen- sorgehäuse des Ultraschallsensors eingebracht werden. Das Sensorgehäuse kann dabei ein- oder mehrteilig sein. Gemäß einer bevorzugten Ausführungsform kann es so ausgebildet sein, daß der Schaltungsträger in einer Richtung parallel zur Längsrichtung der Schenkelabschnitte, bei Verwendung einer Leiterplatte als Schaltungsträger, parallel zur Ebene der Leiter- platte, in das Sensorgehäuse einschiebbar ist. Die ermöglicht ein besonders robustes Sensorgehäuse. Gemäß einer anderen Ausführungsform kann ein Sensorgehäuse mit zwei Gehäuseteilen vorgesehen sein, das so ausgebildet ist, daß der Schaltungsträger in oder auf einem der Gehäuseteile befestigbar ist. Wird als Schaltungsträger eine Leiterplatte verwendet, sind der Ultraschallsender und -empfänger vorzugsweise so angeordnet und gehalten, daß deren Hauptabstrahl- bzw. Hauptempfangsrichtung mit einer durch die Lei- terplatte gebildeten Ebene jeweils einen Winkel kleiner als 5° einschließt Bei dem Verfahren können der Ultraschallsender und der Ultraschallempfänger entsprechend ausgerichtet und mit der Leiterplatte verbunden werden. Unter der Hauptabstrahl- bzw. Hauptempfangsrichtung wird dabei diejenige Richtung relativ zu dem Ultraschallsender bzw. Ultraschallempfänger ver- standen, in die die größte Ultraschallintensität abgegeben bzw. die Empfindlichkeit für ankommenden Ultraschall maximal ist Im Fall von mehreren Maxima wird aus den Richtungen, in denen die Maxima liegen ein Mittelwert gebildet. Diese Ausrichtung bedeutet eine besonders gute Ausrichtung von Ultraschallsender und -empfänger aufeinander. The ultrasonic sensor according to the invention is therefore characterized in particular by the fact that both ultrasound transmitters and ultrasound receivers are held on the same, that is to say only one, circuit carrier which simultaneously enables the electrical contacting of the ultrasound transmitter and ultrasound receiver. It is therefore not necessary to install ultrasonic transmitter and receiver separately in a housing, align each other and then still contact. The production of the ultrasonic transducer according to the invention is thus considerably simplified. The assembly with the circuit carrier and arranged thereon the ultrasonic transmitter, the ultrasonic receiver and also the control and evaluation circuit can be handled simply as a whole. In particular, the U-shaped circuit carrier with the ultrasound transmitter held thereon and the ultrasound receiver held thereon can be introduced into a sensor housing of the ultrasound sensor. The sensor housing can be one or more parts. According to a preferred embodiment, it may be formed so that the circuit substrate in a direction parallel to the longitudinal direction of the leg portions, when using a printed circuit board as a circuit carrier, parallel to the plane of the printed circuit board, in the sensor housing can be inserted. This enables a particularly robust sensor housing. According to another embodiment, a sensor housing may be provided with two housing parts, which is formed so that the circuit carrier can be fastened in or on one of the housing parts. If a printed circuit board is used as the circuit carrier, the ultrasonic transmitter and receiver are preferably arranged and held in such a way that their main emission or main receiving direction with an plane formed by the printed circuit board in each case encloses an angle of less than 5.degree .. In the method, the ultrasonic transmitter and the ultrasonic receiver aligned and connected to the circuit board. In this case, the direction in which the greatest ultrasound intensity is emitted or the sensitivity for incoming ultrasound is maximum is understood to be that direction relative to the ultrasound transmitter or ultrasound receiver. In the case of a plurality of maxima, the directions in which the Maxima are averaged. This alignment means a particularly good alignment of the ultrasonic transmitter and receiver to each other.
Der Ultraschallsender und der Ultraschallempfänger können gleich oder unterschiedlich ausgebildet und/ oder mit dem Schaltungsträger verbunden sein. Gemäß einer ersten bevorzugten Alternative können der Ultraschallsender und/ oder der Ultraschallempfänger Anschlußstifte zur elektrischen und vorzugsweise auch mechanischen Verbindung mit dem Schaltungsträger besitzen. So können die Anschlußstifte mit entsprechenden Abschnitten der Leiterbahnen verlötet sein; wird als Schaltungsträger eine Leiterplatte verwendet, verlaufen die Anschlußstifte vorzugsweise mit ihrer Längsrichtung entlang der Leiterplatte. Die Ansdilußstifte können aber auch in ent- sprechend gestaltete, mit den Leiterbahnen elektrisch verbundene Kontaktmuffen auf oder in dem Schaltungsträger gesteckt sein. In beiden Fällen ergibt sich durch die beiden Anschlußstifte eine verwindungssteife und elektrisch gut leitfähige Verbindung, die eine stabile Ausrichtung und sichere elektrisch Verbindung erlaubt Gemäß einer zweiten bevorzugten Alternative können der Ultraschallsender und/ oder der Ultraschallsender auch ein Ultraschallwandlermodul aufweisen, das ein Montagemodul mit einem Modulgehäuse und einer Montage- modulleiterplatte mit darauf aufgebrachten Leiterbahnen und einen in dem Montagemodul gehaltenen Ultraschallwandler aufweisen. Wenigstens zwei der Montagemodulleiterbahnen des Montagemoduls sind dann mit Anschlußlitzen des Ultraschallwandlers elektrisch verbunden und weisen Kontaktflächen auf, die so ausgebildet sind, daß das Ultraschallwandlermodul zur Montage auf die den Schaltungsträger, auf dem sich zu den Kontaktflächen komplementäre, mit den Leiterbahnen elektrisch verbundene Kontaktflächen befinden, setzbar ist und die Kontaktflächen und die komplementären Kontaktflächen miteinander verlötbar sind. Dies erlaubt ebenfalls eine einfache und sicher Montage der Ultraschallwandlermodule auf dem Schal- tungsträger. Ultraschallwandlermodule der genannten Art sind in der deutschen Patentanmeldung der Anmelderin mit der Nummer 102010026341 beschrieben deren Inhalt hiermit durch Bezugnahme in die Anmeldung aufgenommen wird. Weiter ist es bevorzugt, daß wenigstens einer von Ultraschallsender und Ultraschallempfänger einen Gehäuseboden aufweist, der von einer bzw. der Hauptabstrahl- bzw. Hauptempfangsrichtung des Ultraschallsenders bzw. Ultraschallempfängers abgewandt ist, und der Gehäuseboden an dem Rand des Schaltungsträgers, vorzugsweise der Leiterplatte, anliegt Dies erleichtert nicht nur die Ausrichtung während der Montage auf bzw. an der Leiterplatte, sondern erhöht auch die Stabilität der Ausrichtung des Ultraschallsenders bzw. Ultraschallempfängers, wenn dieser an dem Schaltungsträger gehalten ist. Alternativ oder kumulativ kann der Rand des Schaltungsträgers, vorzugsweise der Leiterplatte, eine Aufnahme für den Ultraschallsender bzw. -emp- fänger aufweisen, in der der Ultraschallsender bzw. Ultraschallempfänger angeordnet ist. Dies erlaubt eine einfachere Ausrichtung des Ultraschallsen- ders bzw. Ultraschallempfängers bei der Montage. Die Aufnahme kann vorzugsweise durch eine Ausnehmung in dem Schaltungsträger, vorzugsweise der Leiterplatte gegeben sein, die eine Breite aufweist, die nur wenig größer als die entsprechende Breite desjenigen Abschnitts des Ultraschallsenders bzw. Ultraschallempfängers ist, der im fertigen Zustand des Ultraschallsen- sors im Bereich der Aufnahme angeordnet ist. Vorzugsweise ist ein Spalt zwischen dem Rand der Ausnehmung und dem Abschnitt kleiner als 2 mm, besonders bevorzugt kleiner als 1 mm. The ultrasonic transmitter and the ultrasonic receiver may be identical or different and / or connected to the circuit carrier. According to a first preferred alternative, the ultrasonic transmitter and / or the ultrasonic receiver may have connecting pins for electrical and preferably also mechanical connection to the circuit carrier. Thus, the pins can be soldered to corresponding sections of the conductor tracks; If a printed circuit board is used as the circuit carrier, the connecting pins preferably extend along their longitudinal direction along the printed circuit board. The Ansdilußstifte but can also be plugged into correspondingly shaped, electrically connected to the conductor tracks contact sleeves on or in the circuit board. In both cases results from the two pins a torsionally rigid and electrically good conductive connection, which allows a stable alignment and secure electrical connection According to a second preferred alternative, the ultrasound transmitter and / or the ultrasound transmitter can also have an ultrasound transducer module which has a mounting module with a module housing and a mounting module circuit board with printed conductors applied thereto and an ultrasound transducer held in the mounting module. At least two of the mounting module tracks of the mounting module are then electrically connected to connecting leads of the ultrasonic transducer and have contact surfaces which are formed such that the ultrasonic transducer module for mounting on the circuit carrier on which are complementary to the contact surfaces, with the conductor tracks electrically connected contact surfaces, can be set and the contact surfaces and the complementary contact surfaces are soldered together. This also allows a simple and safe mounting of the ultrasonic transducer modules on the circuit carrier. Ultrasonic transducer modules of the type mentioned are described in the German patent application of the applicant with the number 102010026341 whose content is hereby incorporated by reference into the application. Furthermore, it is preferred that at least one of the ultrasonic transmitter and the ultrasonic receiver has a housing bottom which is remote from one or the main emission direction of the ultrasonic transmitter or ultrasonic receiver, and the housing bottom bears against the edge of the circuit carrier, preferably the printed circuit board not only facilitates alignment during assembly on or on the circuit board, but also increases the stability of the orientation of the ultrasonic transmitter or ultrasonic receiver when it is held on the circuit board. Alternatively or cumulatively, the edge of the circuit carrier, preferably the circuit board, may have a receptacle for the ultrasonic transmitter or receiver, in which the ultrasonic transmitter or ultrasonic receiver is arranged. This allows a simpler alignment of the ultrasonic transmitter or ultrasonic receiver during assembly. The receptacle can preferably be provided by a recess in the circuit carrier, preferably the circuit board, which has a width which is only slightly larger than the corresponding width of that section of the ultrasonic transmitter or ultrasonic receiver which in the finished state of the ultrasonic sensor in the region of Recording is arranged. Preferably, a gap between the edge of the recess and the portion is smaller than 2 mm, more preferably smaller than 1 mm.
Ein erfindungsgemäßer Ultraschallsensor braucht zwar nur einen Ultra- schallsender bzw. Ultraschallempfänger aufzuweisen. Vorzugsweise verfügt der Ultraschallsensor jedoch über wenigstens einen weiteren Ultraschallsender und einen weiteren Ultraschallempfänger, die beide so an den Schenkelabschnitten der Leiterplatte gehalten sind, so daß Ultraschall von dem weiteren Ultraschallsenders in den Erfassungsbereich abgebbar ist und aus dem Erfassungsbereich kommender Ultraschall des weiteren Ultraschallsenders von dem weiteren als Ultraschallempfänger empfangbar ist. Es ist also wenigstens eine weitere Ultraschallstrecke vorgesehen, die vorzugsweise parallel zu der oben genannten Ultraschallstrecke verläuft Vorzugsweise sind dabei der weitere Ultraschallsender und der weitere Ultraschallempfänger ausgebildet bzw. angeordnet, wie dies zuvor für den Ultraschallsender und Ultraschallempfänger beschrieben wurde, wobei der Schaltungsträger entsprechend modifiziert ist Insbesondere können auf diesem weitere Leiterbahnen ausgebildet sein, die den weiteren Ultraschallsen- der und den weiteren Ultraschallempfänger mit der Ansteuer- und Auswerteschaltung elektrisch verbinden. Letztere kann den Ultraschallsender und den weiteren Ultraschallsender unabhängig voneinander oder gemeinsam ansteuern und/ oder Signale des Ultraschallempfängers und des weiteren Ultraschallempfängers unabhängig voneinander oder gemeinsam auswerten. Although an inventive ultrasonic sensor only needs to have an ultrasonic transmitter or ultrasonic receiver. However, the ultrasound sensor preferably has at least one further ultrasound transmitter and a further ultrasound receiver, both of which are held on the leg sections of the circuit board, so that ultrasound can be emitted from the further ultrasound transmitter into the detection area and ultrasound of the further ultrasound transmitter coming from the detection area can be emitted from the other as an ultrasonic receiver is receivable. Thus, at least one further ultrasound path is provided, which preferably runs parallel to the abovementioned ultrasound path. The further ultrasound transmitter and the further ultrasound receiver are preferably designed or arranged as described above for the ultrasound transmitter and ultrasound receiver, the circuit carrier being modified accordingly In particular, further printed conductors may be formed on the latter, which can be used for the further ultrasound emitters. the and the other ultrasonic receiver electrically connect to the control and evaluation circuit. The latter can independently or jointly control the ultrasound transmitter and the further ultrasound transmitter and / or evaluate signals of the ultrasound receiver and of the further ultrasound receiver independently of one another or together.
Die Erfindung wird im Folgenden noch weiter beispielhaft an Hand der Zeichnungen erläutert. Es zeigen: The invention will be further explained by way of example with reference to the drawings. Show it:

Fig. 1 zeigt einen Abschnitt einer Trarisporteinrichtung 10 für Wertdokumen- te, die Teil einer nicht weiter gezeigten Wertdokumentbearbeitungsvorrich- tung, im Beispiel einer Banknotenbearbeitungsvorrichtung, ist. Die Transporteinrichtung 10 ist dazu ausgebildet, ein Wertdokument in Form einer Banknote 12 entlang eines durch die Transporteinrichtung 10 gegebenen Transportpfades 14 zu transportieren. Hierzu kann sie, in Fig. 1 nur symbo- lisch angedeutet, über von einem nicht gezeigten Motor angetriebene Elemente wie beispielsweise Transportrollen oder -riemen verfügen, die das Wertdokument bewegen und/ oder führen. FIG. 1 shows a section of a valuable document carrying means 10, which is part of a value-document processing device (not shown further), in the example of a bank-note processing device. The transport device 10 is designed to transport a value document in the form of a banknote 12 along a transport path 14 given by the transport device 10. For this purpose, it can only symbolically indicated in FIG. 1 by means of elements which are driven by a motor, not shown, such as, for example, transport rollers or belts which move and / or guide the document of value.
An dem Abschnitt der Transporteirtrichtung 10 ist ein Ultraschallsensor 16 angeordnet, der dazu ausgebildet ist, Wertdokumenten, im Beispiel alsoAt the portion of the transport direction 10, an ultrasonic sensor 16 is arranged, which is designed to value documents, ie in the example
Banknoten, zu erfassen, die entlang des Transportpfades 14 in Transportrichtung T transportiert werden. Bank notes, which are transported along the transport path 14 in the transport direction T.
Der Ultraschallsensor 16 verfügt über einen Sendeabschnitt 18 zur Abgabe von Ultraschall in einen Erfassungsbereich 20 und einen Empfangsabschnitt 22, der von dem Sendeabschnitt 18 abgegebenen, aus dem Erfassungsbereich 20 kommenden Ultraschall erfaßt. Der Ultraschallsensor 16 ist so angeordnet, daß der Transportpfad 14 durch den Erfassungsbereich 20 führt, so daß entlang des Transportpfades 14 transportierte Wertdokumente durch den Ultra- schallsensor 16 erfaßt werden können. Tritt ein Wertdokument in den Erfassungsbereich 20 ein, schwächt es den von dem Sendeabschnitt 18 auf den Empfangsabschnitt 22 abgegebenen Ultraschall auf seinem Weg zu dem Empfangsabschnitt 22. Durch Auswertung der Empfangssignale in dem Erfassungsabschnitt 22 oder von dem Erfassungsabschnitt 22, die eine Eigen- schaft des empfangenen Ultraschalls, beispielsweise dessen Intensität, darstellen, kann daher auf das Vorhandensein des Wertdokuments und/ oder dessen Ultraschalleigenschaften geschlossen werden. Der Ultraschallsensor 16 wird nun anhand der Figuren 1 bis 3 genauer beschrieben. The ultrasonic sensor 16 has a transmitting section 18 for emitting ultrasound into a detection area 20 and a receiving section 22 detecting the ultrasound emitted from the detection area 20 by the transmitting section 18. The ultrasonic sensor 16 is arranged so that the transport path 14 passes through the detection area 20, so that along the transport path 14 transported value documents can be detected by the ultrasonic sensor 16. When a value document enters the detection area 20, it weakens the ultrasound emitted from the transmission section 18 onto the reception section 22 on its way to the reception section 22. By evaluating the reception signals in the detection section 22 or the detection section 22, which generates an intrinsic signal. Therefore, the presence of the value document and / or its ultrasonic properties can be concluded. The ultrasonic sensor 16 will now be described in detail with reference to FIGS. 1 to 3.
Der Ultraschallsensor 16 besitzt ein U-förmiges Gehäuse 24, das aus zwei Hälften 26 und 26' besteht, die mittels einer nicht gezeigten Schnappverbin- d ng miteinander verbindbar bzw. verbunden sind. The ultrasonic sensor 16 has a U-shaped housing 24, which consists of two halves 26 and 26 ', which can be connected or connected to one another by means of a snap-in connection (not shown).
Der Ultraschallsensor 16 verfügt in dem Gehäuse 24 über einen U-förmigen Schaltungsträger, im Beispiel eine U-förmige Leiterplatte 28, die in Fig. 2 zur besseren Erkennbarkeit schraffiert gezeichnet ist. Auf der Leiterplatte 28 sind zwei Ultraschallsender 30 und 30', zwei Ultraschallempfänger 32 und 32' eine Ansteuer- und Auswerteschaltung 34 sowie, in Fig. 2 der Übersichtlichkeit halber nur teilweise gezeigt, auf der Ober- und/ oder Unterseite der Leiterplatte 28 ausgebildete Leiterbahnen 36 zur Verbindung der Ultraschallsender 30, 30' und der Ultraschallempfänger 32 und 32' mit der Ansteuer- und Auswerteschaltung 34 ausgebildet. Weiter ist auf der Leiterplatte ein Steckverbinder 38 gehalten, der mittels auf der Leiterplatte 28 aufgebrachter Leiterbahnabschnitte, die ebenfalls in Fig. 2 nur teilweise gezeigt sind, mit der Ansteuer- und Auswerteschaltung 34 verbunden ist. Die U-förmige Leiterplatte 28 ist einstückig ausgebildet und besitzt zweiThe ultrasonic sensor 16 has in the housing 24 via a U-shaped circuit carrier, in the example a U-shaped circuit board 28, which is shown hatched in Fig. 2 for better visibility. On the circuit board 28 are two ultrasonic transmitter 30 and 30 ', two ultrasonic receiver 32 and 32' a control and evaluation circuit 34 and, in Fig. 2 for clarity, only partially shown on the top and / or bottom of the circuit board 28 formed tracks 36 for connecting the ultrasonic transmitter 30, 30 'and the ultrasonic receiver 32 and 32' formed with the drive and evaluation circuit 34. Next, a connector 38 is held on the circuit board, which is connected by means of the circuit board 28 applied conductor track sections, which are also shown only partially in Fig. 2, with the drive and evaluation circuit 34. The U-shaped circuit board 28 is integrally formed and has two
Schenkelabschnitte 40 und 40', die durch einen Verbindungsabschnitt 42 miteinander verbunden sind. Am inneren Rand der Schenkel 40 lind 40' sind sich gegenüberhegend Aufnahmen 44 in Form von Aussparungen ausgebildet, deren Ränder parallel verlaufen. Leg portions 40 and 40 'which are interconnected by a connecting portion 42. At the inner edge of the legs 40 are 40 'are opposite receptacles 44 in the form of recesses formed whose edges are parallel.
Die Aufnahmen 44 und in diesen die Ultraschallsender 30 und 30' sowie UltraschaUempfänger 32 und 32' sind so angeordnet, daß der Ultraschallsender 30 und der UltraschaUempfänger 32 einerseits und der UltraschaUsender 30' und der UltraschaUempfänger jeweils eine Ultraschallstrecke S bzw. S1 bilden. Das bedeutet, daß der jeweiUge UltraschaUsender und der jeweilige UltraschaUempfänger so ausgerichtet sind, daß von dem UltraschaUsender abgestrahlter Ultraschall durch den Erfassungsbereich zu dem UltraschaUempfänger abgegeben wird. Die UltraschaUsender 30 und 30' sind dabei an dem Schenkelabschnitt 40 und die UltraschaUempfänger 32 und 32' an dem gege- nüberhegenden Schenkabschnitt 40' gehalten. The recordings 44 and in these the ultrasonic transmitters 30 and 30 'as well as ultrasonic receivers 32 and 32' are arranged so that the ultrasonic transmitter 30 and the ultrasonic receiver 32 on the one hand and the ultrasonic transmitter 30 'and the ultrasonic receiver each form an ultrasonic path S or S 1 . This means that the respective ultrasonic transmitter and the respective ultrasonic receiver are aligned in such a way that ultrasound emitted by the ultrasonic transmitter is emitted through the detection area to the ultrasonic receiver. The ultrasonic transmitters 30 and 30 'are held on the leg section 40 and the ultrasonic receivers 32 and 32' are held on the opposing leg section 40 '.
Die UltraschaUsender 30 und 30' und die UltraschaUempfänger 32 und 32' sind im vorUegenden Ausführungsbeispiel gleich ausgebüdet, und umfassen schematisch, aber vergrößert in Fig. 4 gezeigte UltraschaUwandlermodule 46, die einen in den Figuren nicht gezeigten UltraschaUwandler umfassen, der in einem Modulgehäuse 48 angeordnet und über Litzen mit zum elektrischen Anschluß dienenden starren bzw. vergUchen mit einer Litze nur schwer biegbaren Anschlußstiften 50 verbunden ist, die aus dem Modulgehäuse 48 hervorstehen. Die Anschlußstifte 50 sind spielfrei in dem Modulgehäuse 48 gehalten und ragen aus einem im Beispiel ebenen Gehäuseboden 52 heraus. The ultrasonic transducers 30 and 30 'and the ultrasonic transducers 32 and 32' are the same in the above embodiment, and include schematically, but enlarged in Fig. 4 UltraschallaUlmiermodule 46 comprising an ultrasonic transducer, not shown in the figures, arranged in a module housing 48 and is connected via strands with serving for electrical connection rigid or verguchen with a strand difficult to bend terminal pins 50 which protrude from the module housing 48. The terminal pins 50 are held without play in the module housing 48 and protrude from a flat in the example housing bottom 52 out.
Die UltraschaUwandlermodule 46 sind so ausgebüdet, daß deren Hauptabstrahlrichtung H bzw. Hauptempfangsrichtung H (Richtung der höchsten EmpfindUchkeit für UltraschaU) wenigstens näherungsweise senkrecht zu dem Gehäuseboden 52 des Modulgehäuses ausgerichtet sind, d. h. diese Richtungen schließen mit einer Normalen auf den Gehäuseboden 52, wenn dieser wie in diesem Beispiel eben ist, einen Winkel kleiner als 5°, vorzugsweise kleiner als 3°, ein. Der Gehäuseboden 52 ist also insbesondere von der Hauptabstrahlrichtung bzw. Hauptempfangsrichtung abgewandt. The ultrasonic transducer modules 46 are so designed that their main radiation direction H or main reception direction H (direction of the highest sensitivity for ultrasound) is aligned at least approximately perpendicular to the housing bottom 52 of the module housing, ie Directions include with a normal to the housing bottom 52, if this is flat as in this example, an angle less than 5 °, preferably less than 3 °, a. The housing bottom 52 is thus in particular remote from the main emission or main reception direction.
Weiter sind die Anschlußstifte 50 in diesem Ausführungsbeispiel so in dem Ultraschallwandlermodul 46 gehalten, daß sie wenigstens näherungsweise, vorzugsweise mit einer Abweichung von weniger als 1 mm, auf einem Durchmesser des kreisförmigen Gehäusebodens 52 den Gehäuseboden 52 durchstoßen. Further, the terminal pins 50 are held in the ultrasonic transducer module 46 in this embodiment so that they at least approximately, preferably with a deviation of less than 1 mm, on a diameter of the circular housing bottom 52, the housing bottom 52 pierced.
Weiter sind in diesem Ausführungsbeispiel die Richtungen H näherungsweise parallel zu der Längsrichtung der Anschlußstifte 50. Die Anschlußstifte 50 sind mit entsprechenden elektrisch leitenden und mit den Leiterbahnen 36 verbundenen Kontaktflächen verlötet, was in Fig. 2 durch die Linien 54 schematisch veranschaulicht ist. Die Anschlußstifte verlaufen dabei mit ihrer Längsrichtung parallel zu der Leiterplatte 28 bzw. liegen, bis auf durch die Lötverbindung bedingte Abweichungen auf dieser auf. Bedingt durch die Anordnung der Anschlußstifte 50 relativ zu dem Gehäuseboden 52 verlaufen die Ultraschallstrecken zwischen den Schenkelabschnitten 40 und 40' der Leiterplatte 28. Further, in this embodiment, the directions H are approximately parallel to the longitudinal direction of the terminal pins 50. The terminal pins 50 are soldered to respective electrically conductive contact pads connected to the tracks 36, which is schematically illustrated by the lines 54 in FIG. The pins extend with their longitudinal direction parallel to the circuit board 28 and are, except for the solder joint due to deviations on this. Due to the arrangement of the terminal pins 50 relative to the housing bottom 52, the ultrasonic paths between the leg portions 40 and 40 'of the printed circuit board 28 extend.
Darüber hinaus sind die Ultraschallwandlermodule 46 so in den Aufnahmen 44 angeordnet, daß der Abstand zwischen dem jeweiligen Gehäuseboden 52 und dem Rand der Leiterplatte 28 kleiner als 1 mm, vorzugsweise kleiner 0,5 mm ist. Ganz besonders bevorzugt liegt der Gehäuseboden 52 an dem Rand der Leiterplatte 28 an. Die Ultraschallwandlermodule 46 und in diesem Ausführungsbeispiel insbesondere die Anschlußstifte 50 sind so auf der Leiterplatte 28 angeordnet, daß deren Hauptabstrahlrichtungen H, H' mit einer durch die Leiterplatte 28 gebildete Ebene jeweils einen Winkel kleiner als 5° einschließt. Besonders be- vorzugt verlauft In addition, the Ultraschallwandlermodule 46 are arranged in the receptacles 44, that the distance between the respective housing bottom 52 and the edge of the circuit board 28 is smaller than 1 mm, preferably less than 0.5 mm. Most preferably, the housing bottom 52 bears against the edge of the printed circuit board 28. The Ultraschallwandlermodule 46 and in this embodiment, in particular the terminal pins 50 are arranged on the circuit board 28 that their Hauptabstrahlrichtungen H, H 'with an angle formed by the circuit board 28 each includes an angle less than 5 °. Especially preferred
Die Breite der Aufnahmen 44 und der Durchmesser der Ultraschallwandlermodule 46 bzw. deren Modulgehäuse sind so aufeinander abgestimmt, daß der Abstand zwischen dessen Gehäusemantel 56 und der seitlichen Be- grenzung 58 der Aufnahme 44 kleiner als 2 mm, vorzugsweise kleiner als 1 mm ist. Dies erlaubt eine einfache und genaue Montage der Ultraschallwandlermodule beugt gleichzeitig einem Bruch der Lötverbindung durch eine Bewegung parallel zur Längsachse der Schenkelabschnitte 40 bzw. 40' vor. The width of the receptacles 44 and the diameter of the ultrasonic transducer modules 46 or their module housings are coordinated so that the distance between the housing jacket 56 and the lateral boundary 58 of the receptacle 44 is less than 2 mm, preferably less than 1 mm. This allows a simple and accurate mounting of the ultrasonic transducer modules simultaneously prevents breakage of the solder joint by a movement parallel to the longitudinal axis of the leg portions 40 and 40 'before.
Auf diese Weise erfüllen die Anschlußstifte zwei verschiedene Funktionen. Zum einen dienen sie zum elektrischen Anschluß der Ultraschallwandler- module an die Ansteuer- und Auswerteschaltung 34. Zum anderen dienen sie als mechanische Befestigung für die Ultraschallwandlermodule 46 an der Leiterplatte 28 und damit insbesondere auch zur Ausrichtung der Ultraschallwandlermodule 46 aufeinander als Sender und Empfänger, so daß die bereits genannten Ultraschallstrecken gebildet werden, die quer durch den Erfassungsbereich 20 verlaufen. Die Ansteuer- und Auswerteschaltung 34 dient zur Ansteuerung der Ultraschallsender 30 und 30' und zur Erfassung und Auswertung von Signalen des Ultraschallempfänger 32 und 32'. Sie ist in den Figuren der Übersichtlichkeit halber nicht vollständig gezeigt Die Ansteuer- und Auswerteschaltung 34 umfaßt einen mit dem Steckverbinder 38 über Leiterbahnen auf der Leiterplatte 28 verbundenen, auf der Leiterplatte 28 gehaltenen Ansteuerabschnitt 60, der ebenfalls über Leiterbahnen auf der Leiterplatte 28 über die Lötstellen 54 mit den Anschlussstiften der Ultraschallsender 30 und 30' elektrisch verbunden ist und zur Ansteuerung der Ultraschallsender 30 und 30' dient. Die Leiterbahnen zwischen Steckverbinder 38 und Ansteuerabschnitt 60 verlaufen teilweise auf der in Fig. 2 nicht sichtbaren Seite der Leiterplatte 28 und sind daher in dieser Figur nur gestrichelt gezeichnet. In this way, the pins meet two different functions. On the one hand, they serve as the electrical connection of the ultrasonic transducer modules to the control and evaluation circuit 34. On the other hand, they serve as mechanical fastening for the ultrasonic transducer modules 46 on the printed circuit board 28 and thus in particular also for alignment of the ultrasonic transducer modules 46 as transmitter and receiver that the already mentioned ultrasound paths are formed, which extend transversely through the detection area 20. The control and evaluation circuit 34 serves to control the ultrasonic transmitters 30 and 30 'and to detect and evaluate signals of the ultrasonic receiver 32 and 32'. It is not completely shown in the figures for the sake of clarity. The control and evaluation circuit 34 comprises a connector 38 via tracks on the Printed circuit board 28, held on the circuit board 28 drive section 60 which is also electrically connected via tracks on the circuit board 28 via the solder pads 54 to the pins of the ultrasonic transmitter 30 and 30 'and for driving the ultrasonic transmitter 30 and 30' is used. The interconnects between connector 38 and drive section 60 extend partially on the not visible in Fig. 2 side of the circuit board 28 and are therefore drawn in this figure only by dashed lines.
Die Ansteuer- und Auswerteschaltung 34 verfügt weiter über einen Auswer- teabschnitt 62, der über Leiterbahnen auf der Leiterplatte 28 mit dem Steckverbinder 38 verbunden ist, um einen Zugriff auf die Signale zu erlauben. Der Auswerteabschnitt 62 weist insbesondere zwei Empfangsschaltungen 64 bzw. 64' auf, die über Leiterbahnen auf der Leiterplatte 28 mit den über die Lötstellen 54 mit den Anschlussstiften der Ultraschallempfänger 32 bzw. 32' verbunden und auf der Leiterplatte 28 gehalten sind. The drive and evaluation circuit 34 further has an evaluation section 62, which is connected via conductor tracks on the printed circuit board 28 to the connector 38 in order to allow access to the signals. The evaluation section 62 has, in particular, two receiving circuits 64 and 64 'which are connected via printed conductors on the printed circuit board 28 to the soldering points 54 with the connecting pins of the ultrasonic receivers 32 and 32' and held on the printed circuit board 28.
Die Gehäusehälften 26 und 26' des Gehäuses 24 sind so ausgebildet, daß das Gehäuse 24 im Bereich der Ultraschallwandlermodule 46 Offnungen 66 mit sich daran anschließenden, ins Gehäuseinnere weisenden, zylinderförmigen Wandabschnitten 68 besitzt, in denen Abschnitte der Ultraschallwandlermodule angeordnet sind. Zur Vermeidung von Staubeintritt einerseits und zur ungestörten Abgabe von Ultraschall bzw. zum ungestörten Empfang von Ultraschall andererseits weisen die Öffnungen 66 und die Zylinderförmigen Wandabschnitt 68 einen geringfügig größeren Durchmesser aufweisen als die Ultraschallwandlermodule 46. The housing halves 26 and 26 'of the housing 24 are formed so that the housing 24 in the region of the ultrasonic transducer modules 46 openings 66 with adjoining, pointing into the housing interior, cylindrical wall sections 68 has, in which portions of the ultrasonic transducer modules are arranged. To avoid dust on the one hand and for undisturbed delivery of ultrasound or for uninterrupted reception of ultrasound on the other hand, the openings 66 and the cylindrical wall portion 68 have a slightly larger diameter than the Ultraschallwandlermodule 46th
Die Herstellung eines solchen Ultraschallsensors kann sehr einfach erfolgen. Zuerst wird die Leiterplatte 28 mit den Leiterbahnen 36 hergestellt. Mit dieser werden dann die Ansteuer- und Auswerteschaltung 34, der Steckverbin- der 38 und die Ultraschallsender 30, 30'; bzw. -empfänger 32, 32' durch Lötverbindungen verbunden. Dabei werden die Ultraschallsender 30, 30' bzw. - empfänger 32, 32' aufeinander ausgerichtet. In diesem Zustand kann, falls gewünscht, bereits ein Test des Ultraschallsensors ohne Gehäuse durchgeführt werden. The production of such an ultrasonic sensor can be done very easily. First, the printed circuit board 28 is manufactured with the conductor tracks 36. With this then the control and evaluation circuit 34, the connector 38 and the ultrasonic transmitters 30, 30 '; or receiver 32, 32 'connected by solder joints. In this case, the ultrasound transmitters 30, 30 'or receivers 32, 32' are aligned with one another. In this state, if desired, already a test of the ultrasonic sensor can be performed without housing.
Zum Schluß wird die Leiterplatte 28 mit den darauf gelöteten Komponenten nur noch in eine Gehäusehälfte, beispielsweise die Gehäusehälften 26, gelegt, und mit dieser, beispielsweise mittels durch Befestigungslöcher 70 in der Leiterplatte 28 geführter, und in Befestigungselemente in der Gehäusehälfte geschraubter Schrauben, verbunden. Finally, the printed circuit board 28 is placed with the components soldered on it only in a half of the housing, for example, the housing halves 26, and connected to this, for example by means of fastening holes 70 in the printed circuit board 28, and screwed into fasteners in the housing half screws.
Ein zweites Ausführungsbeispiel in den Fig. 5 und 6 unterscheidet sich von dem ersten Ausführungsbeispiel nur dadurch, daß Ultraschallwandlermodule 72 verwendet werden, die auf die entsprechende gegenüber der Leiterplatte 28 modifizierte Leiterplatte 73 gesetzt und auf dieser verlötet werden. Solche Ultraschallwandlermodule sind in der deutschen Patentanmeldung mit der Anmeldenummer 102010026341 der Anmelderin beschrieben. A second embodiment in Figs. 5 and 6 differs from the first embodiment only in that ultrasonic transducer modules 72 are used, which are placed on the corresponding opposite the printed circuit board 28 modified printed circuit board 73 and soldered thereto. Such Ultraschallwandlermodule are described in the German patent application with the application number 102010026341 the applicant.
Hierzu sind ist die Leiterplatte 73 gegenüber der Leiterplatte 28 nur insoweit geändert, als sie eine Montage der Ultraschallwandlermodule auf der Leiterplatte 73 erlauben. Für sich entsprechende Teile werden daher dieselben Bezugszeichen verwendet und die Erläuterungen dazu gelten hier entspre- chend. For this purpose, the printed circuit board 73 is changed relative to the printed circuit board 28 only insofar as they allow mounting of the ultrasonic transducer modules on the printed circuit board 73. Corresponding parts are therefore the same reference numerals and the explanations here apply accordingly.
Die Ultraschallwandlermodule 72 sind gleich ausgebildet, so daß es genügt, nur eines genauer zu beschreiben. Es umfaßt ein Montagemodul 74 mit einem Modulgehäuse 76 und einer Montagemodulleiterplatte 78 mit darauf aufgebrachten Leiterbahnen 80 und einen in dem Montagemodul 74, hier dem Modulgehäuse 76, gehaltenen Ultraschallwandler 82. Wenigstens zwei der Montagemodulleiterbahnen des Montagemoduls 74, hier der Montagemodulleiterplatte 78, sind mit AnschlußHtzen 84 des Ultraschallwandlers 82 elektrisch verbunden und weisen Kontaktflächen 86 auf, die so ausgebildet sind, daß das Ultraschallwandlermodul zur Montage auf die Leiterplatte 73, auf der sich zu den Kontaktflächen 86 komplementäre Kontaktflächen befinden, setzbar ist und die Kontaktflächen und die komplementären Kontaktflächen miteinander verlötbar sind. The Ultraschallwandlermodule 72 are the same design, so that it is sufficient to describe only one more detail. It includes a mounting module 74 with a module housing 76 and a mounting module board 78 thereon At least two of the mounting module tracks 74 of the mounting module 74, here the mounting module board 78, are electrically connected to terminals 84 of the ultrasonic transducer 82 and have contact surfaces 86 formed therein are that the Ultraschallwandlermodul for mounting on the circuit board 73, on which are located to the contact surfaces 86 complementary contact surfaces, can be placed and the contact surfaces and the complementary contact surfaces are soldered together.
Die Ultraschallwandler 82 sind so in Aufnahmen 88 in dem Modulgehäuse 76 gehalten, daß sie mit ihrer Hauptabstrahl- bzw. -empfangsrichtung H parallel zu der Ebene der Montagemodulleiterplatte 78 ausgerichtet sind. Nach der Montage der Ultraschallwandlermodule auf der Leiterplatte 73 sind diese Hauptabstrahl- bzw. -empfangsrichtungen H dann parallel zu Ebene der Leiterplatte 73 ausgerichtet. Die Ausrichtung der Ultraschallwandlermodule aufeinander erfolgt analog zu dem ersten Ausführungsbeispiel. Sie kann dadurch erleichtert werden, daß das Montagemodul die U- förmige Leiterplatte zueinander komplementäre Ausrichtelemente, bei- spielsweise Stifte und Löcher aufweist, die mittels derer das Ultraschallwandlermodul relativ zu der Leiterplatte ausgerichtet werden kann bzw. nach Montage ist. The ultrasonic transducers 82 are held in seats 88 in the module housing 76 so as to be aligned with their main radiating direction H parallel to the plane of the mounting module board 78. After mounting the ultrasonic transducer modules on the printed circuit board 73, these main radiating or receiving directions H are then aligned parallel to the plane of the printed circuit board 73. The alignment of the ultrasonic transducer modules to each other is analogous to the first embodiment. It can be facilitated by the fact that the mounting module has the U-shaped printed circuit board mutually complementary alignment elements, for example pins and holes, by means of which the ultrasonic transducer module can be aligned relative to the printed circuit board or after assembly.
