First Line Definition System

The system includes a printer and a magnetic tape reading and recording apparatus. Provision is made for printing documents unattended but with automatic location of the first line of each document printed.

Printer 1 has single element print head 2 for printing on a series of documents 3a, 3b, etc., connected as a continuous form. Printer 1 has keyboard 4 for informational and functional characters.

Magnetic tape unit 6 has a left-hand tape station 7 and a right-hand tape station 8 with respectively associated read-record circuits 9 and 10. Mode control knob 11 is positioned to establish various modes of operation indicated in mode control 12. Unit 6 has panel 13 with buttons for encoding characters. Reference knob 14 enables the selection of a block of information on one of the tapes at stations 7 or 8 as indicated by a number in window 15. To record information on one magnetic tape at station 7 or 8, knob 11 conditions unit 6 to address one of the stations and establishes a record mode of operation. As keys are depressed on keyboard 4, printer transmit contacts 17 are operated to enter coded characters into bit relay register 18. The characters pass by cables 19 or 20 to the selected read-record circuit 9 or 10. Characters entered from panel 13 pass by cable 21 to register 18. The operation is essentially cyclical in nature and control is exerted by printer 1 on unit 6 by operation of printer feedback contacts in 22, including the carrier return contact C6 having an output on line 23.

To print documents 3a or 3b automatically, a search operation is usually initiated by depression of a button on panel 13 to locate a block of data indicated at window 15. A search control signal on line 25 resets counter 26 as, for example, at points A and C, just prior to the beginning of the printed matter on each document 3a and 3b, respecti...
