Abstract: A combined printing and recording device (such as that described in Specification 1,098,433) in which data from the printer 1 (Fig. 1) may be recorded on a right hand or left hand tape 13, 15, or data from one of the tapes printed and also recorded on the other includes means for altering the form of the data fed from one tape to control the printer (e.g. altering the line length), the other tape recording the data in the form in which it is printed. The apparatus is particularly described for the cases when one or more carrier return codes are read from the tape when the printer is not in its line ending region and when a space is read from the tape when the printer is in its line ending region, in both cases the apparatus being set to its " adjust " mode to alter the format. Carrier return code read from the tape.-Data from the right-hand tape 13 is fed to bit relay register 35 and line adjust logic 48 where a carrier return code is recognized. If the printer is in its line ending region signified by a signal on line 50, a relay (214, Fig. 26, not shown) is energized so that an associated contact (214.4, Fig. 21, not shown) is switched to transmit a signal to operate the carrier return magnet of the printer. When no line ending signal is present the left-hand tape 15 (Fig. 1) is prevented from stepping left by a signal on line 70, which energizes a no step left station relay (193, Figs. 29, 30, not shown). A relay (204, Fig. 21, not shown) is also energized when a carrier return signal occurs outside the line ending region so that at the end of the cycle via associated contacts (204.1, Fig. 26, not shown) store carrier return relay (208) is energized, together with a generate record cycle relay (198, Fig. 29, not shown). When the apparatus is in its " adjust " mode a relay (90, Fig. 14, not shown) is energized so that via a contact (198.2, Fig. 30, not shown) of the generate record cycle relay an active keyboard set-up relay (225, Fig. 30, not shown), a stop relay (79, Fig. 17, not shown) and a collector control relay (22, Fig. 16, not shown) are energized. The collector control relay ensures that the printer is in a shift down mode if the last character printed was an upper case letter. The energization of the keyboard set-up relay (225) switches associated contacts (225.4, Fig. 29, not shown) so that an active keyboard relay (231, Fig. 14, not shown) is energized. This results in active keyboard set-up relay 225 being de-energized to de-energize the transfer relay (228). Stop relay (79) is also de-energized and a record relay (19, Fig. 18, not shown) is energized to establish a record mode. Potential is then applied via printer contacts and switched contacts (204.6, Fig. 29, not shown) to the space magnet (Fig. 21) to close the associated printer transmit contacts in block 8 (Fig. 1) to transmit the space code to bit relay register 35 to record the code on the left-hand tape 15. When a character is next stored in bit relay register 35 the control relay 22 is de-energized and a further relay (194, Fig. 29, not shown) energized to indicate the end of the record cycle. Under the control of contacts of end of record cycle relay (194) the generate record cycle relay (198) is de-energized and a start relay (227, Fig. 30, not shown) energized. Opening of associated contacts (227.6, Fig. 14, not shown) causes active keyboard (231) to be de-energized and transfer relay (228) to be re-energized. Successive carrier return signals.-On recurrence of a first carrier return signal outside the line ending region a space is recorded on the left-hand tape as previously described. However, when the second carrier return code is received with store carrier return relay (208, Fig. 26, not shown) energized, a carrier return no step relay (206, Fig. 20, not shown) is energized so that its associated contacts (206.1, Fig. 25, not shown) switch to supply a signal to backstep left solenoid to step the left-hand tape. The generate record cycle is then initiated by energization of relay (198) via contacts of carrier return no-step relay (206). By further contacts of this relay the carrier return magnet of the printer is energized and as a result printer contacts (C6, Fig. 19, not shown) are transferred and a carrier return feed relay (68) is energized. Carrier return interlock relay (65) and control relay (22, Fig. 16, not shown) are energized so that the carrier return code transmitted by the printer is recorded on the tape. A feed relay (82, Fig. 17) is then energized to control the recording of a feed code from the tape. The apparatus then returns to its adjust mode and the second carrier return code is read again. A space code in the line ending region.- The recognition of a space code in the line ending region results in a space stored relay (211, Fig. 18, not shown) and the line ending relay (214, Fig. 26, not shown) being energized. This results in a carrier return no-step relay (206, Fig. 20, not shown) being energized so the apparatus switches to its active keyboard and record left mode for the carriage return of the printer to be recorded. Hyphen code in the line ending region.-If a hyphen is sensed a relay (213, Fig. 26, not shown) is energized and the hyphen printed. Carrier return followed by a tab code.-A carrier return code followed by one or more tab codes results in the printer effecting this action whether it is in the line ending region or not.
