Abstract: The present invention relates to an apparatus for detecting a skew of banknotes in an automated teller machine (ATM), and particularly, to an apparatus for detecting a skew of banknotes in an ATM capable of more effectively and accurately detecting a defective conveying state of the banknotes passing through a conveying route by including sensors on the conveying route, where the banknotes put into the ATM are conveyed, at regular intervals from each other along a direction crossing the conveying route and detect tips of the banknotes passing through the conveying route to separately detect skew angles for each sector of the banknotes passing through the conveying route based on banknote tip detection signals detected from each detection sensor and support detection of various types of skews of the banknotes, including one-way skew of the banknotes and V-shaped skew at both ends inclined in different directions.

Abstract: The present disclosure relates to a method of operating a bill transport path switching device in an automated teller machine (ATM), which increases the transfer speed of bills by narrowing a transfer interval between the bills and improves efficiency of a bill deposit and counting process, in a way to accurately calculate timing at which each bill enters the bill transport path switching device so that the bills are transferred without an error regardless of whether a transparent part is included in the bill even in a situation in which paper bills and polymer bills are transferred together, by controlling switching timing of the bill transport path switching device that is provided in the transport path of bills within an ATM for handling polymer bills based on a sensor signal of a bill detection sensor that is provided in a discrimination part of the ATM.
