Abstract: A character recognition device for use with printed characters and designed to indicate the character at a plurality of interrogation positions. A storage device is included which will store information relating to a plurality of position digitized signals of a single vertical line element. The information of the vertical line element is modified within the storage device so as to provide an indication of the center of the vertical line element in accordance with one of the interrogation positions.

Abstract: A photoelectric sensing device for providing cyclical indicators of interrogation points in accordance with the width of a sensed character area is constructed with a counter which indicates the first point at the beginning of the first vertical character line of a character, thereby beginning to cycle at a first frequency. At the end of the line, the counter begins again at double the rate. The counter then cycles once between each pair of interrogation points, and the number of zeros emitted by the counter signifies the number of interrogation points.
