Abstract

The arrangement permits manual entry of data in a character recognition system where the system is unable to determine the character scanned. During normal operation of the system, a plurality of recognition output lines from recognition circuits 1 is supplied to output latches 10 via a first And 4, an Or 5 and Decimal-to-BCD translator 9. With the machine in the On-line correct mode, as determined by an input to And 2, a reject signal supplies the other input to And 2. This in turn disables And 4 by the signal supplied through inverter 3. And 6 is now enabled and recognition controls 11 for the flying spot scanner are changed to control the position control circuits 13.

Display and Manual Correction System

The arrangement permits manual entry of data in a character recognition system where the system is unable to determine the character scanned. During normal operation of the system, a plurality of recognition output lines from recognition circuits 1 is supplied to output latches 10 via a first And 4, an Or 5 and Decimal-to-BCD translator 9. With the machine in the On-line correct mode, as determined by an input to And 2, a reject signal supplies the other input to And 2. This in turn disables And 4 by the signal supplied through inverter 3. And 6 is now enabled and recognition controls 11 for the flying spot scanner are changed to control the position control circuits 13. These control the flying spot scanner beam so that display raster control is effective to cause the single rejected character to be displayed on a cathode ray tube monitor.

The operator then visually determines the identity of the character. By operation of the corresponding key on keyboard 8, a signal is caused to be supplied by And 6, Or 5 and translator 9 to output latches 10. Operation of keyboard 8 also causes the reject line to be reset and restores the machine to its normal character sensing mode of operation.

Additionally, a manual entry control switch enables an And 7 to supply information directly from keyboard 8 to output latches 10 to permit the operator to enter fixed data into the system when necessary.
