About the Dictionary

The typeface (called font hereafter) of the characters to be read are “registered” and

“learned” in the dictionaries. Character Recognition Checker reads the characters

based on these dictionaries. Character recognition type A230 has five dictionaries that

can only be used for the character recognition function and up to 40 characters can be

registered in each. OCR

setting is available for all

dictionaries.)
Learning is done after the registration of the extracted letters or symbols (the labeling).

Learning is required each time the content of a dictionary is changed. (The A230 has

an “additional learning” function by which only the changed parts of a dictionary is

learned.)
