Abstract

Die Erfindung betrifft Vorrichtung sowie ein Verfahren zur Aufnahme eines Digitalbilds, umfassend eine Fördereinrichtung (6) zur Förderung der aufzunehmenden Gegenstände (7), insbesondere von Druckwerken, beispielsweise wie z. B. Geldscheinen, in einer vorgegebenen Förderrichtung (R) sowie zumindest zwei auf jeweils unterschiedlichen Aufnahmeeinheiten (1a, 1b) angeordnete, einander zugeordnete, Zeilensensoren (2a, 2b), wobei jede Aufnahmeeinheit (1 a, 1 b) jeweils über eine Optik (4a, 4b) verfügt.The invention relates to apparatus and a method for receiving a digital image, comprising a conveyor (6) for conveying the male objects (7), in particular of printing units, for example, such. B. banknotes, in a predetermined conveying direction (R) and at least two on each different receiving units (1a, 1b) arranged, associated with each other, line sensors (2a, 2b), each receiving unit (1 a, 1 b) each have an optic ( 4a, 4b).

Erfindungsgemäß ist vorgesehen, dass jeder Zeilensensor (2a, 2b) eine Anzahl von Pixelsensoren (3a, 3b) enthält, die jeweils einen von der Optik (4a, 4b) abgehenden Sehstrahl (9a, 9b) aufweisen, wobei die Sehstrahlen (9a, 9b) eines jeden Zeilensensors (2a, 2b) jeweils in einer dem Zeilensensor (2a, 2b) zugeordneten Sehebene (10; 10a, 10b) liegen, dass die Aufnahmeeinheiten (1a, 1b) derart angeordnet sind, dass die Sehebenen (10; 10a, 10b) der einander zugeordneten Zeilensensoren (2a, 2b) identisch sind und im Winkel (β) zur Förderrichtung (R) der Fördereinrichtung (6) stehen, und die einander zugeordneten Zeilensensoren (2a, 2b) jeweils für die Detektion von Licht in voneinander unterschiedlichen Wellenlängenbereichen ausgebildet sind.

Figure imgaf001
According to the invention, each line sensor (2a, 2b) contains a number of pixel sensors (3a, 3b) each having a line of sight (9a, 9b) emerging from the optics (4a, 4b), the line of sight (9a, 9b ) of each line sensor (2a, 2b) are in each case in a lifting plane (10; 10a, 10b) associated with the line sensor (2a, 2b), in that the receiving units (1a, 1b) are arranged such that the lifting levels (10; 10b) of the associated line sensors (2a, 2b) are identical and at an angle (β) to the conveying direction (R) of the conveyor (6), and the associated line sensors (2a, 2b) each for the detection of light in different from each other Wavelength regions are formed.
