Optical character reader

Abstract

Abstract PURPOSE:To decrease the data correcting time, by displaying a character decided unreadable by an OCR on a CRT together with the position of said character and at the same time supplying the correct answer data through a microphone by an operator. CONSTITUTION:A character is scanned optically by a reading device of an OCR (not shown in the figure) and supplied to a CPU after photoelectric conversion and recognition. The CPU performs an operation to display 2 characters, marks, etc. on a CRT1. If an unreadable character 3 exists, a mark ''?'' is displayed on the CRT1. Then a cursor 4 is set at the position of ''?'', and at the same time a picture 5 of the character 3 is displayed. An operator looks at the display 5 and utters a correct data (''KU'' in the figure) at a microphone 9. This correct data is fed to a voice recognizing mechanism 10 and then fed to the OCR in the form of a character code to be displayed at the position to ''?''. Then an input key (not shown in the figure) is pushed after the displayed correct data is confirmed. Thus a corrected data is fed. This facilitates an easy correction of data and decreases the data correcting time.
