Abstract

PURPOSE:To lower the generation rate of a read rejection, by executing an operation check by use of an example character, as for a character pattern of the read rejection, and adopting said example character in case when there is no check error. CONSTITUTION:A character entered on the surface of forms is scanned by a photoelectric conversion part 11 and is photoelectrically converted. A character pattern converted photoelectrically is sent to a recognition part 12, and recognizes the character pattern. In this case, to a recognizable chatacter, a recognition result is outputted in the form of a character code, and on the other hand, to an unrecognizable character, a character code of an example character which is regarded as the most definite is added to a rejection code showing that recognition is impossible, from a character code adding circuit 13, and is outputted. The outputted character code information is sent to a line buffer 14 and is stored. The character code information of one line portion, which has been stored in the line buffer 14 is operated and checked by a checking circuit 15. If there is an error as a result of the operation check, a character pattern showing that recognition is impossible is displayed on an indicator, and or there is no error, the rejection code is removed.
