The reader performs the check character computation below:
(0 x 1 + 1 x 2 + 2 x 1 + 8 x 2 + 4 x 1 + 5 x 2 + 4 x 1) modulo 10
= (0 + 2 + 2 + (1 + 6) + 4 + (1 + 0) + 4) modulo 10
= 0
Since the result is zero, the message is considered to be valid, so
the reader outputs the message: 012845
OCR ISBN Application Example
One application of OCR is to read the ISBN characters typically
encoded using the OCR-A or OCR-B font. This is especially
useful when the ISBN number is not encoded in an EAN-13 bar
code. The following example shows how to
configure the imager to read the ISBN strings on books in Japan.
After you have followed the steps below, you will be able to scan
the following ISBN number or the additional data below it,
depending on the line of text at which the imager is
aimed.
1. Scan the OCR-B On bar code
2. Program the user-defined variable “g” to comprise the ten digits
plus the dash: 0123456789-
3. In Japan, it is common for two fields to follow the ISBN number,
the three digit price field, and the four digit price field. The first
field typically starts with a “C” (uppercase c), followed by four
digits. The second field typically starts
with a “P” or a yen symbol, followed by three or four digits,
followed by an “E.” Program the user-defined variable “h” to
comprise the “P” and the yen symbol (represented by a backslash).
