The subsequent review of the document often reveals errors, Omissions or repetitions found that are desirable

should be corrected step by step without having to rewrite the entire text of the document.

It is just as common that an in a certain format A document written or with a certain arrangement is to be brought into a different format or a different arrangement, be it by narrowing or expanding the lines of the pleading. It is obvious that a format or arrangement Changing the document by hand would require a lot of time and effort.

The control part of the system according to the invention contains facilities for scanning the occurrence of various groups of data including the scanning of a character, word, sentence or stopping the data entry system after the occurrence of any character, space or other group of data, if the system is switched to automatic writing. In this way, additional information can be stored in the data carrier on the output side including a written page or magnetic tape.

; Various working or ; Calculation codes either converted into other work or calculation codes or switched off from the output device. For example are carriage returns that are not in the right edge zone occur, converted to a single space bar movement if the carriage return is not preceded by punctuation.

909848/0774

In the latter case, two space keys are created in the control section. Space bar or tab operations that occur in the right edge zone are also converted into a carriage return operation, to ensure that the data is not written on the same line after a logical break in the line has been scanned. Successive space or tab operations that occur in the right edge zone are converted into a single carriage return process by switching off further wa- ; Genreturn commands implemented.

A delimiter can be scanned either inside or outside the right edge zone. In the first case, this will be Separator characters written or transferred to the data carrier and a carriage return is generated after the separator character, to start a new line on the data carrier. However, if a separator is scanned outside the right margin then this character and every carriage return following the character are skipped with an empty command. The attachment was also interpreted in such a way that a delimiter was written; regardless of where it is scanned. Through this Facility, a precedence code is generated in front of the separator to indicate that the separator is definitely output j will, regardless of whether it is inside or outside the right! Edge zone occurs. If the separator is with precedence code occurs outside the right edge zone and is followed by a carriage return, this carriage return is returned with an empty command skipped.

- 5 909848/0774

A carriage return is also triggered if there is a separator is scanned with a priority code in the right edge zone, regardless of whether a carriage return is programmed via the data input was or not. The command for the carriage return is also transferred to the data carrier or the data output device, although it occurs outside the right margin when it has a precedence code to the leader.

The invention aims to create an improved control system ^] , namely the data input from a data memory is stopped when a preselected event occurs in order to be able to control the data output manually and to scan the occurrence of a preselected event for the purposes of print editing or editing to be able to. Furthermore, when the occurrence of a preselected data group is scanned, the control should be able to stop the automatic data input device for checking the data by hand and for the necessary correction or print preparation work. The invention is also intended to facilitate print editing or data recording for a printer and / or another recording device. Likewise, finding the location or writing location of the data information should be made easier by preselected features in order to enable manual control of the correction method for this data. The invention is also intended to provide an improved automatic correction or control system that can only be used in

^! selected data areas is working. There is also an improved system for controlling the data format on the data carrier.

Accordingly, the flip-flop is either deleted or deleted when a space bar, a tabulator or carriage return movement occurs. when scanning a write code that does not contain any punctuation, if the system is not in the "skip" operating mode (Empty command) or switching to capital letters works.

The punctuation flip-flop 150 is controlled in the same way by the gates 170, 172 and 174, which provide question marks, exclamation marks and colons, the outputs of these three gates being connected to one another and in turn connected to the setting output line 143. The question mark gate 170 is controlled by the signals on the data bus channels 3 »^. 5 and Έ via the lines 178 and via a write-decoding signal on the line 130 is controlled. The gate 172 is controlled by bits in the channels 1, 2, ¥, 5 and o ", which are supplied via the Lei tang Ib2; the gate 172 also responds to a Sohreib decoding signal on the line I30.

Finally, the gate 174 is driven by bits in the data channels 1, 2, 3, 4, 5 "and δ", which are fed to it via the line IO4; likewise, the gate 174 is activated before a write-decode signal from the line I30. All of these gates 170, 172, 174 control the Interpuructions-Plip-Flop ISO and delete it again Ln in the same way as it was described in connection with the gate 140.

Certain operating functions are by the device of Fig.r scanned and decoded, special the tabulator, carriage return, space bar, and shift functions to uppercase and lowercase letters. The tabulator function is scanned by a tabulator gate, with an input signal from data collection channel 1 being applied to gate l88. that is impressed on the input line I90 and an input signal from puncture inversion circuit 70 connected to gate I88 the line 192 is fed.

The output of gate 368 is at the level of a logic I 0 when the correction flip-flop 290 is switched on, the radio

j functions of switching between uppercase and lowercase letters or ■ of writing can be scanned and the level of the signals on the Line 362 is on a logical 1. The gate 372 responds to the switching on of the flip-flop 380 for the right edge zone, where this signal runs over the line 3 ^ 2 as well as on the generation a space or tab code on input line 382 for space-tab signals carried over line 384 is running.

The flip-flop 380 for the right edge zone is created by the differentiating circuit 384 and the "AND" gate 386 is activated. At the entrance of the "AND" gate is a signal on the separator line from input line 352, a signal from line 388 for the right margin switch, indicating that the right margin switch is operated, an input from the second Carriage return function that goes through inversion circuit 390 and line 392 and finally a signal on line 394 for the edge position, which is fed in via line 396 will.

Flip-flop of carriage return 1 is activated, which is indicated by a signal from line 4l4 and finally by the scanning of a space, tab, or carriage return 2 signal, as indicated by a signal on line 412.

The output of gate 438 is used to block the reading or scanning device, if the system works in marginal operating mode

and the flip-flop of carriage return 1 in addition to one the spacebar, tabulator or carriage return flip-flops are activated. The exit gate 440 responds to the activation of the flip-flop for carriage return 1, which is indicated by a signal from line 4l4 and the scanning of a Shift codes for the lower and upper case letters or a writing code, which is indicated by a signal on the line 4j> 2. The output of gate 440 thus drops to the level of a logic 0 when the flip-flop of carriage return 1 is activated and a shift code for uppercase or lowercase letters or a writing code has been scanned.

Finally, an additional clear signal is sent through the reset gate 444 is generated, at which the input signal of the "AND" gates 446 and 448 is present. There is an input signal from the gate 446 Input line 302 for the automatic correction as well as a Input signal from the reset side of the right edge zone flip-flop 380 on. If the system is in the "automa-. table correction "works and the right edge zone flip-flop is activated, then there is a signal at the output of gate 446 with the level of a logic zero. This signal is raised to the level of a logic one if either of the two conditions is met 1st not fulfilled, i.e. that either the right edge zone flip-flop is not energized, or the system is not in the "Automatic correction" mode is working.

At gate 448 there is an input signal from differentiating circuit 450, which is activated when the signal is on the output line 452 of the start switch from a logic zero level

Pig. 3 shows the circuit AH 30.10, which forms another part of the system according to the invention. The output line 456 for the skip function or the empty command generates an empty command output signal, if the system is in the peripheral zone. This signal on line 466 is passed through the "AND" gate 468 is generated at which an input signal from the input line 470 for the edge position and from the output of the "OR" gate 472 is present. The "OR" gate is different from everyone

In particular, the gate 472 is responsive to the sampling of a signal from the carriage return 2 as well as the generation of a tab toggle code for uppercase or lowercase letters and a write code which are indicated by a signal on the input line 474. Furthermore, the gate 472 is controlled by an empty tab command, empty carriage return command and a stop code, which is indicated by signals on the input lines 476, 478, 480. If the system is working on the right edge mode and a space bar or tabulator function is scanned ₉ , an output signal is generated by the "AND" gate 484 because this gate is connected to the input line 486 for the right edge zone and the input

Operation and punctures of gates 498 and 502 are explained below. The gate 472 is thus controlled by various puncture and operating conditions in the system, including the tabulator, empty command, carriage return and stop functions. The gate 472 also responds to the state when the system is switched to right-hand edge operation and to the connection of the flip-flops for carriage return 2, the space bar and the tabulator. Gate 472 also senses the generation of a turn-on signal for the delimiter or space bar-tab flip-flops followed by a write code.

The output of carriage return 1 is through the flip-flop 510 generated for carriage return 1, which is via the output line 512 is running and a signal for carriage return 1 is on the

In addition, the flip-flop 510 is driven by a signal generated by the "AND" gate 502, which is fed to ^{it via the line 52 1 I.} The gate 502 generates an output signal with the logic zero level in dependence on the fact that the plant is in the right edge zone, which is indicated by a signal on the line 468 and is fed to the gate via the line 526, as well as in dependence on the generation a write code of the uppercase or lowercase conversion, which is indicated by a signal on the input line 528, and in dependence on a signal with the logic level 1 of the "OR" gate 530. The "OR" gate 530 is activated by the Deletion of the space bar-tabulator flip-flop 554 or the scanning of a separator is activated. In addition, flip-flop 510 is turned on by a carriage return signal generated on input line 538 for carriage return initiation.

The flip-flop 510 is activated by a clear signal on the input line 5 & Q cleared, which is fed in via line 542 or from an output signal from one of the two differentiating circuits 544 or 546. Differentiating circuit 546 is made up of a

Carriage return signal 2 on input line 548 is controlled by a two-carriage return signal (2 CR) on the input line and by a clock signal C, which ^{is displayed on input line 55 1} I for timing C. The second differentiator 544 has input signals from the "AND" gate 502 as described above and from the input line 556 for punctuation and right edge functions. The differentiating circuit 554 is also activated by a signal with the level of a logic one on the input line 506, an ^{override code generated by the "AND!} " Gate 496, a 2 CR signal generated on the input line 560 and a space key or generated on the line 562 Carriage return 2 signal energized The differentiating circuit is controlled in response to a clock signal C on line 554 to clear flip-flop 510.

The carriage return 2 signal is generated by the carriage return 2 flip-flop 568 on output line 556. Of the Flip-flop for carriage return 2 is activated by an output signal driven by gate 498 on line 570 or by an output signal from differentiating circuit 574. The differentiating circuit is triggered by a carriage return signal on the carriage return line 520 and the activation of the carriage return flip-flop 510.

The flip-flop 568 is reset by a clear signal on the input line 540, which is fed in via the line 596, or by an output signal from the differentiating circuit 600. The differentiating circuit 600 has an input signal from the input line 602 for the carriage return and a skip signal the line 6o4 generated by the jump gate 6o6. At the skip gate 606 there are input signals from the "OR" gate 472 and the margin control input line 586. Finally, the differentiating circuit 600 is controlled by a signal on the input side 610 as a function of the scanning of a space bar, tab, carriage return or write function. The gate 530 responds to a separation cell signal on the input line 612 and to the activation of the space bar or tab flip-flop 534. The priority "AND" gate 498 provides a logic zero output in response to the sensing of the condition that the carriage return flip-flop 510 is de-energized and the space or tab flip-flop 534 is not is turned on, and that the operating mode Umschaltspeicher _s is true as indicated by a signal having the level of a logic one on the input line 620 for the switchover

Flg. 4 shows the circuit system AH 40.10 with the counter 660 on binary flip-flop Baais, whose first counter part 662 for It is used to count the number of tab functions that appear in the first line of each paragraph and a second line Counter part 664 based on binary flip-flop, which is used to count the The number of tabulator functions that appear in the following lines of a paragraph is used. The facility can also do everyone Drop the following tab functions that occur after the necessary tabs have been set up like them by the tabulator position of the first sentence of a paragraph is determined.

The binary counter 662 includes a number of flip-flops 670, 672 and 674 corresponding to bit counts 1, 2 and 4. Each of these Flip-flops will use input signals from the differentiating circuits 676, 678 and 680, which in turn relate to a special switch-on or delete condition of the corresponding flip-flop address a control or feedback circuit. The binary counter 662 is a normal state-of-the-art binary counter. The inputs to binary counter 662 are through the "AND" gate 684 given, the gate being opened by a clock pulse D. the input line 686 is controlled by a function signal on the line 688, an empty command on the line 690 and by the tab code, a bit in channel 1 that is attached to the Input line 694 is displayed. Gate 684 becomes dependent controlled by the switched-on state of the tab counting flip-flop 700, which is explained in more detail in connection with FIG.

As will be explained below, the tab count flip-plop is talking 700 responds to the sampling of a double carriage return command. The output voltage of the flip-flop 700 is over the line 702 fed to the input of the "ÜND" gate 684.

When all of the above conditions occur, gate 684 controls the signals on data line 1 via input line 694 to the first differentiating circuit 676. The first differentiating circuit drives flip-flop 67O, indicating that a tab function has been scanned. The second signal on data bus 1 clears flip-flop 670 and activates flip-flop 672. The flip-flops 67O to 674 are turned on and cleared to indicate that the tab binary count at the "AND" gate 684 has been sampled. When scanning a carriage return, the gate 684 is switched off by the reset status of the flip-flop 700 (FIG. 5). The flip-flop 700 will is cleared in response to the scan of a single carriage return command, and then gate 684 does not transmit further signals to the flip-flops 670 to 674, if not a double Carriage return is scanned.

The counter 664 contains the three binary flip-flops 710, 712 and 714, which by the three differentiating circuits 7l6, 718 and 720, which are connected to the corresponding inputs of the flip-flops 710 to 714. The counter 664 is used for Counting the number of tabulator functions generated in the second and subsequent cells of a paragraph, where

j signal occurs on input line 730 for setting a tab, this tab setting signal always being generated; when a single carriage return occurs. This tab set signal is provided by tab set flip-flop 734 (FIG. 5), as will be explained in more detail below. The binary counter 662 "A" is reset by a counter clear signal on the input line 732, whereby all binary flip-flops 670 to 674 are cleared in response to a signal on the line 732. The outputs of the flip-flops 67O to 674 and 710 to 714 are fed to a number of "AND" gates 736-750 in various combinations and permutations. A channel from the binary counter 662 and a corresponding channel from the binary flip-flop 664 are assigned to each of the gates 736 to. At the input of gate 736 there is an input signal from channels Ta and IF as well as input signals from channels 2a, 2b and 3a and 3b. The signals control the gate 736 with the aid of a clock generator C - signal, which is impressed on the input line 754 and is fed to the gate 736 via the line 756. The gates 736 to 750 are used to compare the output signals of each flip-flop of the counter 662 with the corresponding flip-flops of the counter 664.

-35-

901148/0774

Accordingly, each port 736-750 compares the corresponding channel of flip-flop 662 with flip-flop _{66H 3 to} obtain an output of gates 736-750 when a comparison of the scanned channels occurs. The outputs of gates 736-14 are passed through "OR" gate 758 to clear flip-flop 73H by a signal asserted on output line 760. The resetting of the flip-flop 73 ^ is indicated by a signal on the output line 762 for tab setting (FIG. 5), which in turn is connected to the tab setting input line 730. This line 730 clears all flip-flops 710 to 7i4 in order to make the counter 66H ready again for a count of the tabulator functions in the following line. From the circuit of the tab counting flip-flop 700 in FIG. 5 it can be seen that the tab counting flip-flop is controlled by a switch-on signal from the "ÜND" gate 770. At the gate 770 there is an input signal from the input line 772 of the clock pulse C, which is fed to the gate via the line 77 ^ and an input signal from the input line 776 for carriage return, which is fed to the gate via the inversion circuit 778. Furthermore, an input signal from the input line 780 for the tabulator control and a carriage return signal from the input line 782 are present at the gate 770. The gate 770 thus controls the flip-flop 700 with its output signals. The flip-flop 700 is cleared in response to the scanning of a single carriage return command, specifically an output signal from the gate 788. At the gate 788, there are input signals from the output of the gate 770, which are supplied via the line 790, from the input line 782 for the

Car return and from the right edge zone line 792. Corresponding the flip-flop 700 is turned on in response to the scanning of a double carriage return command and in dependence from scanning a single carriage return command turned off.

The clear signal from the gate 788 is controlled in response to the fact that the system enters the right-hand edge zone, which is indicated by a signal on line 792 for the right edge zone and on the differentiating circuit 79 ¹ I and the line 796 of the right edge of zone line 792 fed will. The reset side of flip-flop 700 is then energized by the non-occurrence of a tab control signal on line 780. The output of the connection side of the flip-flop 700 is fed in on the one hand via the line 702 of the circuit of FIG. 4 and on the other hand the output line 800 for the tab counting. The reset side output is applied to the tab count output line 802. The output signal of the tab counter circuit is also fed via this output line to the input of gate 806 for empty tab commands via line 808. Gate 806 issues tab empty commands to skip the following tab positions after the right edge zone and the required tab count have been reached, this last state being scanned by binary cell 664.

There is also an input signal from the delete side at gate 806

flip-flop 734 to indicate that tab set flip-flop 734 was cleared by scanning a single carriage return. The flip-flop 734 is controlled by a signal state in the differentiating circuit 810, this differentiating circuit responding to a carriage return, to an empty command, to a space bar tab signal on line 812 and a carriage return 2 signal and a carriage return 2 signal on the output line 8l6. The flip-flop 73 ¹ J is cleared as a function of the sampling of a comparison state in the counters 662 and 664 as a result of the output signal from the "OR" gate 758 (FIG. 4), which is fed in via the line 760 to the reset side of the flip-flop 734 will. The resetting of the flip-flop 734 is carried out or njdit carried out depending on the fact that the system is operating in the tab control mode, which is indicated by the corresponding signal on the input line 780 for the tab control.

Input signals from the keypad input line are also available at gate 8O6 820, indicating that the keypad is not powered on, from the tab control input line 780, the arithmetic input line 688, which are fed via the line 822 to the gate 8o6 and finally from the Data bus line 1, which is fed to gate 806 via line 824 will.

Since the logic levels of all control switches with the exception of the word switch are wrong, only the input gate of the word flip-flop is activated. the Storage capacitors of the word flip-flops are used during the tent of 1.6 milliseconds. charged and the switching state of the word flip-flop changes on the falling edge of the output pulse from the monostable multivibrator.

Note that the illuminated margin switch or auto correction switch does not indicate that the System is working in margin setting mode or in "automatic correction" mode. The system only runs in the Marginal operating mode when both the marginal flip-flop is activated and the keypad is not switched on or when the input / output device is switched to the "scanning" mode is. Thus, if the carriage does not stop in the right edge zone as a result of the "automatic correction" operating mode, then so cause a manually specified carriage return, a separator, a space bar and tabulator function from the keypad off no margin setting operations.

The second space bar signal is generated by the CRl flip-flop, as is normally the case The case would be if the carriage return was preceded by a punctuation; would. The scanning lock prevents the scanning or reading device advises the tape or the punched tape to continue to run in order to keep the UC code in the reader.

Figure 11 shows the system in the record mode, for example when a Period and a double space bar are scanned. The hole

strip is encoded with a period (punctuation) and two space keys ψ , which generate a number of clock pulses C. Of the

Dot switches the gate for uppercase or lowercase letters device or the write process to and also the punctuation flip-flop. The scanning of the space bar controls the correction flip-flop and the reader is after scanning the second space bar paused. The keypad is turned on so that the input / output device feeds the data the scanning of the end of each sentence in the text can be corrected by hand.

When the capital letter A is scanned, the gate for switching between uppercase and lowercase letters or for the write function is activated and cfer correction flip- ¹ Pl op is energized.

Figure I ^ shows the not working in the margin setting mode System when a carriage return is scanned or the system is switched to line mode. In this situation shows the carriage return of the system indicates that the end of a line has been reached and the system must stop. The tape or the punched tape will for example encoded with the letter A, a carriage return

signal and the letter B. At the end of the capital letter Λ there is the gate for switching between uppercase and lowercase letters or the write operation is de-energized and the scanning of the carriage return switches the gate 286 for the line and the carriage return away. By scanning the end of the carriage return signal, the Korrekt.ir-Plip-Plop 290 is activated and when scanned of the letter B a stop signal is generated, which the reader persists. When the reader stops, the keypad is turned on to allow manual correction material into the written page can be inserted.

controls and switched off after the end of the point code. By scanning the carriage return, the gate 624 is controlled for space bar and tabulator or carriage return 2 processes in the circuit AH 30.10. The flip-flop 510 for carriage return 1 and the gate ⁱ yj6 for carriage return 1 are also activated. At the end of the first carriage return, the correction flip-B ¹ Iop 290 is also switched on and a stop code is generated at port A 368. This stop code causes the reader to stop, switches off the code for switching capital letters and switches on the keypad so that correction material can be entered manually.

The Pign. I5 to 20 show the system in the marginal operating mode, In the margin setting mode, the right margin is automatically checked if a prepared punched tape or a prepared Band is changed or the manual setting is changed from an earlier document. Thus, the edge or the format of a written page is expanded or reduced compared to the format programmed in the data carrier, In this case the punched tape or the tape.

In order to be able to carry out this process, are not in the edge zone Occurring carriage return and separator codes in spaces umgfJti * t /, t mti not considered. On the other hand, spacebar and TabuLjtijrcodes, which are signs of the end of a word, as well as "pricking stitches in the edge zone in carriage returns. In the execution game shown, a marginal zone is used

determined by an edge switch, which is approx. eight space keys before (in the case of the right edge zone) or after (in the case of the left edge zone) the activation of the margin stop sign is actuated. This distance or this number of spaces can be changed from system to system or can be converted within a system.

Figure 15 shows the sequence when a carriage return is in a space bar is implemented on the left edge zone. By scanning

u of the first data code is the gate 246 for the capital letters or Switching between lower case letters and writing is activated and the scanning of a carriage return controls the carriage return flip-flop 510 CRl. This information is saved as long as until the second data code is sampled. This scan controls the space bar and tabulator flip-flop 534 and locks the reader via gate 438. At the end of the first scanning lock signal a signal IB3 is generated at port A 416.

If a carriage return code is scanned when both CR1 and CR2 are in the wrong switching state, an incorrect ¹ CR empty command signal appears at the output of gate A6j4 in edge control mode. A false signal is also given at the gates' exits

is keyed, the output of the gate 624 is false and does not trigger the differentiating circuit 544. So in the end it becomes CRl of the carriage return pulse is switched to the true switching state via the differentiating circuit 514.

After the reading device has stopped a second time and scanned a write code, the input line 506 of the CRl dot write process becomes false and switches the flip-flop 534 to the true switching state and prevents CRl from being cleared by the differentiating circuit 544. By the turn of the flip-flop ψ 534, the outputs of gates 622 and 4 ^ 4 are wrong or at zero. The reader is blocked by this state and a new clock cycle is started at the end of the clock pulse C. In the new clock cycle, channel 3 is stored in the register at the end of clock pulse B. Thus, a space bar is read by the input / output device and processed further.

Figure 16 shows the margin setting mode when a carriage return is scanned at the left margin and ignored. Of the Punched tape is coded with the capital letter A, a space bar, a carriage return and the capital letter B. When scanning the Capital letter A is the gate at 46 for uppercase or lowercase switching or the writing process at the beginning of the A switched on and switched off at the end of the capital letter A. The spacebar-tab-flip-flop 5 ^ 4 will be on scanning controlled by a space bar code and the empty command gate

for the carriage return is dependent on the scanning of a Carriage return activated.

FIG. 17 is very similar to FIG. 15 in that the carriage return is converted into a space bar on the left edge zone when ^: the system is operating in the edge setting mode. However, the carriage return follows a punctuation, in this case a period, and the carriage return is converted into two spaces to indicate the end of a sentence. In the case of Fig. 17, the punctuation is sampled and controls the punctuation flip-flop 150 *. The ^{output 1} of gate 436 drops to the zero level in response to a punctuation signal and a signal from the right edge zone. The remainder of FIG. 17 is essentially the same as that of FIG. 15, except that it still contains the circuitry for converting to the second space key.

In Fig. 18 the case is shown that a separator cude is skipped in the left edge zone when the system is switched to the edge setting mode. The punched tape is coded, for example, with the capital letter A, a separator and the capital letter D. The gate 346 for the uppercase or lowercase letter switching or the write function is raised to the level of a logical 1 every time a letter is scanned, in this case the uppercase letters A and D. The right edge zone and the priority gate 4 JO fall a if zero ab and the empty bVf ehTs Igna 1 am Γ or 468 becomes i'alnoh, ilamit da «Tr-er

characters in the input / output device are skipped can.

However, the carriage return and the separator, if preceded by a precedence code, are always scanned and processed by the input / output device. In the preferred exemplary embodiment, the priority code is selected for a capital letter shift code. If the code for the capital letter switching is scanned or entered manually from the keypad, the gate 210 in the circuit AH 10.10 generates a positive pulse at the time of the w clock pulse C and thus overrides the switching memory PLLP-Plop 214 the differentiating circuit 212 on the falling edge of the clock pulse C on. At the end of the clock signal D the first code, which is not another shift code or carriage return code in the line mode, the flip-flop 214 is cleared. If a code for the uppercase letter changeover or codes for the uppercase letter lowercase letter changeover with CRl and SPT scanned in the wrong switching state; can be (not during the time during which the codes are converted or generated), then the gate ¥ jb in Fig. 3 is wrong, whereby the CR2 flip-flop 568 is switched to the true switching state and the empty command gate 6.34 CH blocks.

SPT flip-flop 534 is switched to the true switching state. If the following code is a write or shift code, so during the time of the clock pulse C there is an incorrect output signal at gate 502, with the clock pulse C a Empty command pulse emits and the CRl flip-flop 510 to the true Switching status changes. With the activation of the space bar tabulator flip-flop 53 ^ and the CRl flip-flop 5IO becomes the reader locked and a new clock pulse cycle initiated. Of the Output of gate 410 of FIG. 2 causes the carriage return code is stored in the register of the input / output device. The carriage return code is then passed through the input / output device processed. The operation of the system is not affected if there is no carriage return code between the space bar and write code occurs or there is more than one space bar code.

FIG. 20 shows the case in which the system is operating in the margin setting mode and a separation character code is scanned in the right margin zone vrlrd. This condition indicates that a zei Ahen by separation separate word occurs in the right peripheral zone and the line must be terminated by the generation of a carriage return signal. In this case the separator is scanned and the separator flip-flop 102 is activated, and when the system is scanned that the system is in the right edge zone, the CR1 flip-flop 510 is also switched on. The reader is then blocked and a carriage return is

FIGS. 21 to 23 show the "automatic correction" operating mode when certain codes are scanned by the reader, for example when a changeover or write code is scanned. The Pign. 22 and 23 also show the function of the system in converting a space or tab function to a carriage return function or in generating a carriage return code after a hyphen to indicate the end of a word or the hyphenated part ψ of a word. The purpose of the automatic correction mode is to cause the reader or scanner to stop in the edge zone and step forward at a time when a start skip or no write key is pressed in order to allow the operator to pinpoint the edge can control and control.

When the system is working in the "automatic correction" mode (the automatic correction switch is illuminated) then the automatic correction gate 280 is true when the Car is located in the right edge zone. The right edge zone begins for the duration of a clock pulse C. The correction state occurs at the end of the clock signal C when a toggle or iSchreibcode is scanned and the reader on the next toggle or write code halts unless a space or tab function has been entered manually.

In Pig. 24 the system works in the tab setting mode,

'in the tab count in the first line of the data block ; is carried out and tab operations automatically after a full

¹ drawn carriage return can be generated by the system.

This tab counting is done by two 3-bit counters in the circuit AH 40.10 carried out. The counter A counts and stores the tabulator functions in the first line of the data block while the counter D counts the tab operations after a carriage return in the following lines of the same data block. The content of these two counters is compared with one another ίand the generation of tab signals stopped when in the system The signals are identical or there is an identical count between the content of counter A and that of counter B.

The system provides three ways of clearing counter A, with the resetting of counter A indicating the beginning or the end of a data block. There are three ways to do this: 1. Two or more consecutive carriage returns; 2. a carriage return in the priority mode; }. at the time when the

Tab set flip-flop first switched to the true switching state will.

In the tab setting mode, both the Randstöll flip-flop and the tab setting flip-flop are activated. In circuit AH 30.10, CR2 is in the true switching state: firstly after a carriage return has been completed and secondly in the priority mode. Therefore, the output voltage of gate 770 in circuit AH 40.10 is low during the clock pulse C of the second carriage return code or a carriage return is scanned and processed by the system in the W priority mode. This output voltage is sent to the output of gate 1162 and gate ΙίβΟ the Circuit AH 60.10 connected, the output pulse of which is low during the time of the clock pulse D for the second manually entered carriage return and l, o millisec. takes place after pressing the start button. The wrong logic level resets counter A to zero and switches the tab counting flip-flop to the true switching state.

. With the true switching state of the tab counter and one not If the tab code is skipped, the output of gate 684 drops to the level of a logical 0 at the beginning of the clock pulse D, which triggers the first stage of counter A. At the first tabulator operation the CR2-Fllp-Flop was set to the wrong switching state. At the end of the first line a carriage return or sampled., and the output of gate 788 falls to the level of a giBohtm ü and deletes the tab counting flip flip 700.

then the gate is switched off by \ and the tabulator counting is interrupted until a new data block begins.

In the tab setting mode, the switching status of the space bar tab flip-flop (SPT) true if the carriage return is generated in the right margin zone and a single carriage return in the left edge zone is skipped by an empty command. In the case of multiple carriage returns, the SPT signal can only occur if the first two carriage returns are skipped by an empty command and then generated automatically and the system doing the 2 CR (CR2) signal while generating these two carriage returns gives away. Thus, the switching state of the differentiating circuit 810 in the circuit AH 40.10 is only during the duration of the clock pulse C of a single carriage return not skipped in tab setting mode is true. The differentiating circuit 810 controls the tab set flip-flop, which is the reset line of counter B switches off so that counter B can count tab operations, locks the reader against execution of program steps and the sampling; enables the system to trigger a clock pulse A at the end of the clock pulse pulse C. and stores the channel 1 flip-flop (the tab code) in the register. This way, tab operations are ongoing generated until an output signal with the level of a logical 0 at the gate "75Ö, which indicates * that the required Number of generated tabs has been submitted or the Number of tab operations is the same, which are stored in counter A

jsetz-Plip-Plop switched to the wrong switching state.

If the punched tape is changed to automatic by manual input is, the tab setting device is activated if the SPT flip-flop was switched on before a carriage return. The attachment however does not automatically set the tabs because the '840 gate is locked by the keypad signal. The tabulator ! Flip-flop is reset to the wrong switching state after the number of manually entered tabs becomes equal to the number of tabs stored in! counter A.

Therefore, when the system j is operating in the line or paragraph mode, the reader stops at the first tab code instead of the shift or write code of a new data block in the tab setting mode if the data block is not formed by a single carriage return in the priority mode and the line mode is not activated.
