856,550. Character recognition devices. NATIONAL CASH REGISTER CO. March 20, 1959 [April 14, 1958], No. 9683/59. Class 106 (1). As described, characters, each having a distinctive width, are sensed by a single broad magnetic, Fig. 1, or photo-electric (not shown) scan, to produce signals which after being shaped and clipped should appear as shown in Fig. 4. These signals are distributed, by the first ten pulses, from a transistor oscillator 26, which is started by the first pulse sensed from the character, to a register 20 of ten cores. The eleventh pulse from the oscillator transfers the stored data from the register 20 to a ten-core recoding register 29 which is so arranged that the only core that is set " on corresponds to the last pulse produced by the sensing of the character. The twelth pulse from the oscillator resets the recoding register producing an output on a single line which is passed to an indicating unit 37 of which no details are given and completes a recognition cycle. |
