Bill serial number reading device and bill serial number reading method

摘要

The device has a serial number reading section (25) with two light sources having different emission colors and an image sensor. A denomination identification section (24) identifies denomination and transport direction of a bill on a transport path. A control unit (4) selectively drives the sources based on the identified information and controls the section (25) to scan and read a bill portion. The bill whose denomination cannot be judged are sent to a reject holding section (22). An independent claim is also included for a bill serial number reading method for reading a serial number of a bill to be transported on a transport path.
