Abstract

In order to provide an audit trail, some mark and character readers have facilities for printing a serial number on each document which has been scanned. If a mechanical incrementing printer is employed in this capacity, the initial number set into the printer must be entered in the stored record generated from reading the corresponding documents.

Serial Number Initialization for an Optical Mark Reader

In order to provide an audit trail, some mark and character readers have facilities for printing a serial number on each document which has been scanned. If a mechanical incrementing printer is employed in this capacity, the initial number set into the printer must be entered in the stored record generated from reading the corresponding documents.

In a mark reader of this type, the printer is first set manually to a desired number. This number is transferred to a card 10, Fig. 1, by holding the card over the print wheels while depressing a "print" switch on an operator's console. The printed serial number 11 is manually copied into boxes 12, and the appropriate bubbles 13 of each mark-read on an operator's console. The printed serial number 11 is manually copied into boxes 12, and the appropriate bubbles 13 of each mark-read column are blackened in accordance with the individual digits in boxes 12. A console "format load" switch is depressed, and card 10 is fed into the mark reader in the same manner as any other document to be read. Instructions for the above sequence of operations may be pre-printed in an area 14 of the card.

A microprogrammed controller in the mark reader posts the serial number by a procedure 20, Fig. 2. When block 21 senses that the format-load switch is on, block 22 detects the presence of a long timing mark 15 on card 10. Block 23 then collects and decodes marks 13, when enabled by th...
