AI Technical Summary

Technical Problem

Existing banknote dispensing devices struggle with inaccurate detection of double feeding and can mistakenly identify banknotes with holograms as double feeds, especially when the light-blocking properties of banknotes are low.

Method used

The device employs a double-feed detection sensor that outputs values based on light shielding at multiple addresses, using reference data specific to each address and direction, and incorporates a banknote passage detection sensor to differentiate between double feeds and holograms, with threshold values for accurate detection and appropriate rejection or stop processes.

Benefits of technology

This approach enhances the accuracy of double-feed detection, allowing for early identification and appropriate handling of double feeds, reducing errors and improving the reliability of banknote dispensing.

Abstract

To provide a banknote dispensing device that can detect double feeds more accurately. [Solution] A banknote dispensing device 1 comprises a dispensing banknote storage section 2, a banknote transport passage 3, a banknote dispensing outlet 4, a double-feed detection sensor 6, and a control unit 9. The double-feed detection sensor 6 outputs an output value corresponding to the amount of light shielding of the banknote 100 for each reading address N. The control unit 9 determines that a double-feed has occurred when the accumulated value obtained by sequentially accumulating the portion of the output value of the double-feed detection sensor 6 that exceeds the reference value of the reference data from the first reading address N0 exceeds a predetermined first threshold. The reference data is a combination of the reading address N of the double-feed detection sensor 6 and the reference value, and is created based on measurement data of the output value of the double-feed detection sensor 6 when there is no double-feed.
