Bill serial number reading device and bill serial number reading method
First Claim
1. A bill serial number reading device for reading a serial number of a bill to be transported on a transport path, comprising:
- image reading means which has at least two light sources having different emission colors and an image sensor;
identification means for identifying a denomination and direction of the bill being transported on the transport path; and
control means for selectively driving the light sources based on information on the denomination and direction identified by the identification means and controlling the image reading means so as to scan and read a portion where a serial number of the bill being transported is printed.

Abstract
The present invention recognizes denomination and transporting direction of each bill to be deposited when the bill is deposited, selectively drives two light sources with different emission colors based on the recognized information on the denomination and direction of the bill, and scans and reads the portion where the serial number of the bill being transported is printed by means of an image sensor, so that the serial number of this bill is read while selectively changing the emission color of the light source according to the denomination of the bill. Even if the character color or background color of the serial number differs depending on the denomination, the serial number can be accurately recognized without providing many light sources with different emission colors.

8. A bill serial number reading device for reading a serial number of a bill to be transported on a transport path, comprising:
-
identification means for identifying a denomination and direction of the bill being transported on the transport path;
image reading means for selectively driving light sources based on information on the denomination and direction identified by the identification means, and scanning and reading a portion where the serial number of the bill being transported is printed; and
serial number recognition means for extracting the serial number area from output image data of the image reading means based on the denomination and direction information of the bill and recognizing a character of each digit of the serial number from image data of the serial number area, replacing a character which cannot be recognized with an error character which indicates a recognition error, and adding the error character to recognized characters to output as a recognition result. - View Dependent Claims (9, 10, 11, 12)

13. A bill serial number reading method for reading a serial number of a bill to be transported on a transport path, including image reading means which has at least two light sources having different emission colors and an image sensor, the method comprising:
-
identifying by identification means disposed on the transport path a denomination and direction of the bill being transported, controlling the image reading means by selectively driving the light sources based on the identified information on the denomination and direction so as to scan and read the portion where the serial number of the bill being transported is printed, and reading the serial number of the bill while selectively changing the emission colors of the light sources according to the denomination and direction of the bill. - View Dependent Claims (14, 15, 16)

17. A bill serial number reading method for reading a serial number of a bill to be transported on a transport path, comprising:
-
a step of identifying a denomination and direction of the bill being transported on the transport path;
a step of selectively driving light sources based on the identified information on the denomination and direction, and scanning and reading a portion where the serial number of the bill being transported is printed; and
a serial number recognition step of extracting the serial number area from the image data acquired by the scanning and reading based on the information on the denomination and direction of the bill, and recognizing the character of each digit of the serial number from image data of the serial number area, replacing the character which cannot be recognized with an error character which indicates a recognition error, and adding the error character to recognized characters to output as the recognition result. - View Dependent Claims (18, 19)
