Embodiment Construction

[0037] figure 1 Shown is a device 10 for processing value documents, in this example a bank note processing device, in particular for determining the status and authorization of value documents 12 in the form of bank notes. The apparatus 10 has: an input container 14 for inputting value documents 12 to be processed; a singler 16 which is accessible to the value documents 12 in the input container 14; a conveying device 18 which has successive Arranged doors 20 and 20'; and each output container 26, 26', 26" after each door and at the end of the conveying path 22 following the two doors. Along the conveying given by the conveying device 18 The path 22, before the door 20 and after the picker 16, is arranged with a sensor assembly 24 for capturing properties of the value documents 12 supplied in picked-off form and forming sensor signals representing these properties. The control device 30 via the signal Connections are connected at least to the sensor assembly 24 and to the do...

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.

Description

technical field [0001] The invention relates to an ultrasonic transducer module for an ultrasonic sensor for detecting and / or checking a value document, to an ultrasonic transducer module for detecting and / or checking a value document An ultrasonic sensor, and a method for manufacturing the ultrasonic sensor. Background technique [0002] A value document in this connection is to be understood as a sheet-like or card-like object, which represents, for example, a monetary value or an authorization and should therefore not be produced arbitrarily by unauthorized persons. Therefore, they are characterized by being not easy to manufacture (in particular copying), and their existence is represented as authorized, ie manufactured by authorized subjects. Important examples of such value documents are chip cards, coupons for merchandise, coupons, checks and especially bank notes. [0003] Ultrasound is frequently used when machines process documents of this value, especially bank ...
