Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to word processing systems, and more particularly to an apparatus for inspecting the content and format of text automatically displayed or printed by a word processing system.

More specifically, the present invention relates to an apparatus for ejecting text and instruction codes associated with such text. Word processing systems that can type typewriter typed text quickly and error-free are well known in the art; It usually includes a typewriter or printer connected to and controlled by the memory for storing information.

Therefore, the operator of the word processing system prepares a first draft of the desired text, keys in it with the desired format and instructions for the reproduction of such text, and saves all these data for subsequent processing. input into memory. As a result, various changes, additions and deletions are often made to the originally drafted text. The prior art device is then able to produce an error-free final draft of the text in accordance with the desired format without having to retype portions of the text that do not change. This type of device not only saves the secretary a great deal of time, but also allows the person who prepared the text to review portions of the text that remain unchanged to ensure that typographical errors have been eliminated. There is no need to reread it all the time. Therefore, while such word processing systems may be able to replace previous non-automatic typewriters and have significantly greater effectiveness than them, there are still problems that have not yet been overcome in order to take full advantage of the advantages of such systems. There are some.

Specifically, obtaining the correct format of the text requires the operator to input the correct instruction code. Therefore, if the preliminary printing of text is done in an incorrect format (e.g. due to an incorrect opcode), the operator avoids having to completely delete the incorrectly formatted portion. Therefore, in order to correct it, it is necessary to determine which instruction code is incorrect. Therefore, unless the system has some means of allowing the operator to "look into memory," the existing set of instruction codes must be traced to a considerable degree by guesswork, which is usually very This could only be done by a highly skilled operator, as these instruction codes were generally not visible on hard copy. It is an object of the present invention to provide a new and improved apparatus for enabling an operator of a word processing system to accurately determine the nature of formats and associated instruction codes present in memory. The goal is to provide the following.

Another object of the present invention is to provide a new and improved apparatus for effectively inspecting the content of text and the instruction codes associated with such text prior to final printing of the text in a desired format. It's true. It is another object of the present invention that an operator of a word processing system, apparently at any stage of the operation of such a system, be able to read not only the input text but also the set of instruction codes associated with such text. The objective is to be able to obtain a preliminary printout on hard copy representing some of the information.

For these and other purposes, the present invention provides for pre-printing or printing each line of text originally typed by an operator along with a visible (printed or display) representation of the non-transitory instruction code associated with such line of text. It is aimed at display devices.

Specifically, by such preliminary printing, referred to as an audit print, a line of text mixed in the printed character display of the instruction code is composed of the text and the instruction code characters mixed in such a manner. Occurs with the number of referenced rows immediately preceding each accessible row. According to the unique configuration of the present invention, as will be explained below, this inspection printing allows "font change" including a two-digit font number (number) display.
It becomes possible to print an exchange identification symbol indicating the existence of an instruction and its instruction code. As will be seen from the detailed description below, the apparatus of the present invention allows for optional processing of the text without having to play out the entire text (or most of it) or waiting until the work is finished. An operator can selectively examine (and determine the instruction code associated with) any text line at any time. Please refer to FIG. 1 first.

This generally depicts a conventionally well known word processing system to which the present invention is intended to be applied. It includes a typewriter or printer 1 equipped with a keyboard 2, which is in two-way communication with a console 3 by a cable 4. Disposed within the console 3 are memory and control circuitry that can automatically record text and instruction codes generated by the operator so that the printer can later automatically play out the text according to the desired format. As is well known in the art, an operator of a word processing system using a keyboard 2 not only types desired text, but also enters various instruction codes relating to the desired arrangement or format of that text. Starts the corresponding operating mode in the system.

Accordingly, as shown in FIG.
Other keys or buttons are provided (when pressed) for inputting text characters and command codes (indicated by "T (text)" and "tab/index" in the example). may be specified. 1st
It should be understood that the locations of the keys shown in the figure are shown for convenience of explanation and do not necessarily represent their actual locations.0 Also, what is happening in the memory of the printer 2? An operator message panel 5 may be provided to display this information to the operator.

The console 3 is also typically provided with a slot 6 for a magnetic card, such as one manufactured by IBM, which records coded text, instructions, etc. for later use. In conventional use of the word processing system of FIG. 1, the operator first typically "keys in" some formatting command (e.g., line length, tab index (line spacing) requests);
Then type the first draft of the text.

The text and related instruction codes are transferred and stored within the console's memory so that, after making corrections and insertions to the initial draft, the final finished reformat of the text is readable by the operator in accordance with its desired format. automatically printed with as little intervention as possible. The inspection printing operation performed by the apparatus of the present invention allows the operator, at any given stage of the operation of the word processing system, to print not only the text, but also command codes that are specifically related to the text and control its format. A display of some of the images can also be obtained as a hard copy embossing.

As will be explained in more detail later, what is so printed is the reference line number immediately preceding each accessible text line and the print character corresponding to (and displaying) each such instruction code. Contains along with various lines of text. With this arrangement, the operator can now playback and reprint virtually anything that is in memory, allowing for each line to contain not only the text but also the pre-filled information associated with that text. It also determines the code that was added to the line (as well as the text itself) and changes or modifies the existing code associated with that line's text (as well as the text itself). (by pressing the corresponding key). For convenience of explanation, terms used in the following explanation will be mentioned.

A "text code" is a coded representation (as it appears in memory) of text (letters, numbers, etc.). On the other hand, a "text character" refers to an actual display of such text, that is, a printed hard copy. The "opcode" corresponds to the way the text is printed (as it appears in memory)
Refers to each code (therefore, tab indent (beginning of line), tab, carrier return, stop, index (line feed)
(It will probably include code that commands the positioning of formats, etc.) "Test print characters" refer to important ones of these respective instruction codes actually displayed on a display or printed. To avoid confusion, "inspection printing instruction code" refers to a code represented by "inspection printing characters," and is used to distinguish it from other instruction codes in memory as necessary. Since both the text characters and the test print characters are mixed as hardcopy prints, to avoid operator confusion between the two, each test print character must be marked with an initial symbol called the "identification character." followed by a second symbol called the "code character".

This first "identification symbol" is common to all "inspection print characters" and therefore makes its presence noticeable. On the other hand, the subsequent "code character" specifies one type of the inspection print command code represented by the code character. Having understood that various types of symbols or combinations of symbols may be used for test print characters, the following is a list of the sets of symbols used to represent the test print command codes. This is a collection of test print characters.

It will be understood that in this embodiment, "0" is used as the first identification symbol. Basic Concept of Inspection Printing The basic concept of inspection printing is schematically expressed in the data flow diagram of FIG.

In particular, a text code (represented by signal 10) and an instruction code (represented by signal 11) are transferred from a storage medium such as a keyboard 2 (or alternatively a magnetic card 7) to a text buffer 1.
3 by the text buffer control device 12. Although a detailed description of the construction and operation of text buffer 13 (and cooperating text buffer controller 12) is not necessary for an understanding of the present invention, U.S. Pat.
No. 75,216 describes an exemplary buffer and buffer control system. For convenience of explanation, text buffer 13 will be described as a recirculating dynamic shift register for storing input text and instruction codes along with control flags (bytes) associated with those data and advanced to move that data out of the buffer. Please understand that this is the basic explanation. Text buffer 13
The output from the print control device 8 is connected to the print control device 8 through the gate 14, and the output of the print control device 8 is connected to the printer 1. The printer 1 and its associated printing control device 8 are of a conventionally known type, and may be of a construction manufactured and commercially available by the applicant. Thus, as will be explained in more detail later, the text (and instruction) code in text buffer 13 is output to print controller 8 upon activation of gate 14, resulting in the printing of the text characters on printer 1. be done. A test print character generator 9 is also connected to the seal plate 1 controller 8 via a gate 15, and generates a code representing each test print character.

Further, the input of the inspection print character generator 9 is connected to the decoding section 13a of the text buffer 13. Its operation and details will be described later. When activating the gate 5, these codes are passed to the printing control device 8 and are used to later print test print characters on the printer 1. A third device 16 containing reference line number data is connected to the print controller 18 via a gate 17 so that when gate 17 is selectively energized, the reference line number code is transferred to the print controller 8.
As a result, in the process of "inspection printing" of the present invention, the text code from the text buffer 13 and the number of reference lines from the inspection printing character generator 9 are gated sequentially. The test print instruction code and the reference line number data code from the reference line number generator 16 are selectively gated to generate a mixture of text characters and test print characters for each accessible data consisting of such mixed data. A test printout from printer 1 is provided, along with the reference line number printed at the beginning of the line.

Thus, before producing a final copy (shown as sheet 20 in FIG. 2) consisting of the text described above, the operator places the system in the test printing 7-board and produces a mixture of text characters and test print characters. (Sheet 201 in Figure 2)
) occurs on the text sheet. For example, the example text below titled "FinaeTextSalnple (finishing text example)" is sheet 20.
This is a typical example of the data typed out above.
uditpriJ. The embossing example entitled tSan]Ple (Example of Test Printing) shows an example in which the same text is printed with test print characters corresponding to the instruction codes for generating such text.

As you will have noticed, each accessible row in this test print example is preceded by a reference row number, which allows the operator to review, access, and access that particular row. Any related instruction code can be quickly corrected or changed. "Accessible row" means "row forward (
1ineadvance” or “line return (1iner)”
This means a line that can be accessed by pressing down the key corresponding to "Eturn)". In one example, 1
An "accessible line" can be two or more printed lines, but not less than one printed line. Apparatus of a Preferred Embodiment Here, the configuration and operation of an apparatus of a preferred embodiment for producing "inspection printing" of the present invention will be explained.

In order to clearly understand this operation, we will first summarize the meanings of terms used to identify various signals that will appear in the following explanation.

RDsCHAR and ACCESS are all generated by the keyboard decoder 2a (FIG. 4). The circuitry within the decoding device 2a is well known for generating the coded Switch Gogo as described above in response to depressing a corresponding key or button on a corresponding keyboard 2a. . Other signals summarized above, discussed in more detail later, include:
A signal that is generated internally by a logical device in the system. Furthermore, as is also conventional, the complement data signal is typically generated using a well-known inverter, a typical example of which is shown in FIG. 4A. In explaining the operation of ``Positive logic (POsitive logic) 1, let's take it.

Therefore, the terms "high level" and "low level" (or "1" and "0" refer to the presence and absence of a particular signal, respectively.
It is to be understood that ``gativelOgic'' may alternatively be used in these logic networks, in which case each applies to the opposite designation. In the following discussion, it will be noted that all latches are stepped synchronously by a common clock (not shown), and that the signal state at the output of a latch is constant at its input until each clock is generated. It is assumed that the signal information does not change to reflect the signal information.

Under normal conditions, the ``set'' and ``reset'' inputs do not reach high levels during mouthing, but if such an event were to occur, ``set'' takes precedence over ``reset''.
Printing Text Characters Referring to FIG. 3, a logic control circuit for printing (or suppressing) text characters by printer 1 is shown.

Therefore, the sequential advancement of the control flag and the corresponding advancement of the text (and instruction) code to the output of the text buffer 13 is caused by the 0R gate 18 (coupled to the input of the text buffer controller 12). This is done in response to the generation of an "Advance Flag" signal at the output. As is clear from FIG.
RINTCOMMAND goes high), (2
) Occurs upon completion of striking out a test print character (PRINTF high) or (3) after mode line length (MMEND high). Gate 14 (Figure 2) is A in Figure 3.
The ND gate 21 plays a fundamental role, so that the AND gate determines whether the data at the output of the text buffer 13 is gated to the print control logic 8 (along data buses 24 and 25). It depends on whether the signals at inputs A and B of 21 are both high.

If the system remains in either automatic playout mode, line playout mode, or word playout mode (the inputs to 0R gate 22, AUTOsILINE or WORD, are at a high level) and (1) the system is in test print mode; No (input I to NAND gate 9
AUDIT is at a low level) or (2) the system is in test print mode but the reference row count is not being processed, a carrier return is not in progress, or one of the 18 test print instruction codes is is not detected or the inspection print end state does not exist (NUM to 0R gate 23

As shown in FIG. 3, these 0R gates have some of their inputs connected together as well as being individually connected to corresponding outputs of the text buffer decoder 13a. AU from keyboard decoder 2a (Figure 4)
T.O. The LINE and WORD outputs are applied to the "set" inputs of latches 26-28, respectively. Thus, when AUTO is "L", latch 26 is set (generating AUTO), and when LINE is "1", latch 26 is set (generating AUTO). 27 is set (generating ILINE) and when WORD is ``1'', latch 28 is set (generating IWORD). Latches 26-28 are thresholded upon the occurrence of certain input signal conditions (AUTO.ILINE or IWOR, respectively).

or AUDITRSET, as well as when either input signal occurs. Additionally, latches 26-28 are activated when the system is not in test print mode (IAUDIT is input to AND gate 30) and when the system is "stopped" or "
"font exchange" condition exists (S to 0R gate 29
It is set when the TOP or FONCHG signal is input. Printing of Inspection Print Characters A logic circuit for inserting (mixing) inspection print characters during inspection printing will now be described.

Before such a description, it may be best to first describe the apparatus for generating certain signals used to control the insertion of such test print characters. Therefore, referring first to FIG. 5, the text buffer decoding device 13a reads the 18 test print instruction codes present in the text buffer 13, as well as mode/line length, tab/index, minimum word spacing, and dead space. 1 (printing without escape) Editing has the function of generating a signal corresponding to an error code. Additionally, a flag status logic device 38 connected to the output of the text buffer 13 determines whether the control flag is
It serves to generate a signal indicating the section position, ie, whether the control flag is at the beginning or end of the section. The logic circuitry for entering and exiting the test print mode and for indicating whether the system is in the test print mode (IAUDIT) or not (IAUDIT) is shown in FIG.

Therefore, AND gate 31 connects its output to latch 32's
AND gate 37 connects its output to the "RESET" input of latch 32. In order to start the inspection printing mode in this way, the AND gate 31 is
A match must be obtained for all signal states appearing at the inputs to the AUDITSET
The control signal AUDI is generated from the latch 32.
A display signal T is generated.

Once started, the system uses AND gate 33, NO

9 and an inverter 40.

Connected to the input of the 0R gate 39 is the test print instruction code signal output from the text buffer decoder 13a.

Figure 16 shows the alternative section instruction code (ALTSEC).
2 shows a shift register that generates an ALTLAT signal in response to a signal. Referring now to FIG. 8, the test print command code signal (from the text buffer decoder 13a) is connected to the input of the code generator 50, which is actually the second
It plays the role of the inspection printed character generating device 9 shown in the figure.

Specifically, the code generator 50 generates three "sections (
Sections 50a and 50b generate the [identification symbol] portion of the inspection print character, and section 50c generates the “code character” portion of the inspection print character, as will be explained later. do. As can be seen from FIG. 8, upon receiving a particular signal, for example a TAB signal, at the input to section 50c, it provides its corresponding code letter, in this case [t], to multiplexer 51. This identification signal data is transmitted to the data bus 54.
and 55 to multiplexer 51, and the code character data is input to multiplexer 51 along data bus 56.

Multiplexer 51 actually serves as gate 15 (FIG. 2) for gating test print character data (identification symbols and code characters) to print control logic 8. Such "gate operation" is achieved by a group of signals (PRINTA) generated by sequential step circuitry 60, which is described in detail in FIG.
-PRlNTF) and or AND gates 52 and 5
Occurs in response to the output of 3. Therefore, when the sequential step circuitry 60 is energized, the stamp 1th{I for inserting and printing the test printing characters by the printer 1 is sent to the control unit 8 by the multiplexer 51 (segments 50a and 50b).
The identification symbol data (from segment 50c) and code character data (from segment 50c) are gated. According to a particular embodiment of the device of the invention, the code generator 50
In addition to generating the normal identification symbol (mentioned above), it can also generate an exchange identification symbol (in this example, the symbol "6") if so commanded (ALTSYMB).

Therefore, the AI. When receiving the TSYMB signal, the exchange identification symbol "αD" is transmitted to the code generator 5.
0 sections 50a and 50b to multiplexer 5
1 is input. If no such exchange identifier command exists (ALTSYMB), sections 50a and 50
b will input the normal identification symbol "O" to the multiplexer 51. According to other features of the code generator 50:
Both the normal identification symbol and the replacement identification symbol are in section 5.
Note that it is formed from two overlapping segments generated by 0a and 50b, respectively. For example, "0" is formed by ")" generated from section 50a and "(" generated from segment 50b. Therefore, both segments are sent to multiplexer 51 [
If it is entered along with "backspace code", part 2
The two parts overlap when printed, resulting in the identification symbol "0".
This also applies to the case of two overlapping "o"s. As previously mentioned, the "font change" code letter consists of an initial symbol "F" followed by a two-digit font number.

This entire code letter not only requests a font change, but also
It also identifies a two-digit number representing the type of font to be used. For example, the code represented by F79 may represent a copper plate gothic. The current font number is typically stored in a font number register 62, the output of which is connected to a two-digit code generator. Therefore, when receiving the ONTCHG check print instruction code, not only "F" but also the appropriate two digit number representing the particular font is sequentially input into multiplexer 51 along data buses 57 and 58. In brief summary, test print insert printing by printer 1 occurs in the following order under and in response to control of sequential step circuitry 60.

i.e. (1) first print an identification symbol (normal or replacement) and (2) then (correspond to a specific test print instruction code)
print the specific code character; and (3) also print the two-digit font number if the test print command code indicates a font change. The printing of this inspection print character is as follows.
AUDITPRINT SAMPLE" 5 is inserted into the appropriate position along with the stamped text to produce a mixed stamp similar to that previously stamped. Referring again to FIG. 8, note that AND gate 64 also connects its output to the input of printing machine 8.

This is actually done to ensure that inspection print characters, especially identification symbols (if preceded by a single dead character), are not overprinted on top of text characters, and therefore IAUDB and PRTSE.
Administrative control is provided to ensure that the carrier is spaced across the l position (before printing) when the S signal state occurs. IAUDB signal is latch 6

The ESET signal AND starts printing the test print character.
This is a one cycle pulse from gate 66 (FIG. 9).
Referring now to FIG. 9, sequential step circuitry 60 includes a plurality of shift registers 70-75 connected in sequence to the output of AND gate 66. Referring now to FIG.

Thus, when an inspection print character is inserted (IAUDIT
and AUDITCHAR and other signals at the inputs to AND gate 66), PRTSET goes to ``1'', which causes print signals PRINTA to PRINT
F starts sequentially. These sequential step signals gate the identification symbol and code character data through multiplexer 51 to print controller 8 as described above. As seen from AND gates 52 and 53 (FIG. 8), sequential step signals PRINTE and PRINTF control the printing of the font number. As mentioned above, printing of text characters is temporarily stopped while inserting test print characters (

. According to a characteristic feature of the invention, not only are the test printing instruction codes printed during test printing, but some of these codes also initiate a functional response after the printing insertion of the respective code. do.

Specifically, with reference to FIG. 11, carrier return (CR), required carrier return (RCR), platen advance (INDEX
)] and Zero Index Carrier Return (ZICR)
requires that a carrier return be performed after each print.

This occurs at PRIMTE time. This is 0R gate 6

Referring to FIG. 6, the page end (PAGEND) inspection print command code is output to AND gate 3 at PRINTF time.
3. Terminate the inspection print playout (after its printing) via the 0R gate 36 and the AND gate 37. This A
The UDITSET signal also issues a modified line return command to the text buffer controller 12 (FIG. 6) to return the control flag to the beginning of the line (if it is not already there) and to return the AND of FIG. If the carrier is not yet at the beginning of a new line, as indicated by gate 80, CAU is sent to print controller 8 via 0R gate 69.
Outputs the SECARRIERRETURN signal. As discussed below, the AUDITSET signal also initiates playout of the first reference row number. Note that certain types of instruction codes that are not inspection print instruction codes, such as seven-word/line length codes, tab/index codes, and minimum interword space codes, are also issued during inspection printing. is printed on a separate line rather than along with the text characters, as is the case with test print instruction codes.

Before proceeding with that discussion, it may be useful to first describe the apparatus and method for generating the signals used to control the firing of this reference row number. Please refer first to FIG. 12. The sequential step circuit network 90 includes a plurality of shift registers 8 connected in series to the output of the AND gate 85.

3 shows a logic circuit that generates an IAUDZ signal indicating whether the IAUDZ signal is high (Z, low level) or not. This circuit includes a latch 91 which is ``set'' when the printing of the reference line number is completed (NUMD3) and ``reset'' by moving the carrier back to the left margin, ie to the starting point of the test print. . When the AUDZ signal is low, it indicates that the reference line number needs to be printed. As mentioned above, Figure 13 shows the AU
A rack 92 for generating the DR signal is shown. FIG. 14 shows an apparatus for embossing reference line numbers during inspection printing.

This corresponds to the counter 76 and R7 of the modulus 10 (which essentially provides the function of the reference row number generator 16 of FIG. 2).
and a 4-bit multiplexer 78 (which essentially provides the functionality of gate 17 of FIG. 2). counters 76 and 7
The outputs from 7 are connected to the A and B inputs to multiplexer 78, respectively. A third input c to multiplexer 78 inputs the space location code to print control logic 8. A counter 76 that stores the number of next reference lines to be printed.
and 77 are first set to 01 at the start of inspection printing (presence of AUDITSET signal), and if the IAUDB signal is at a low level (under the J control of AND gate 92 in FIG. 14), each reference line number is printed. It is incremented by one for each time. Primarily under the control of AUDB (or its data complement, the IAUDB signal), multiplexer 78
functions to gate an appropriate code to the print control device 8 while printing the reference line number.

IAUDB or 1AUD to ensure that reference line numbers are placed only on accessible lines of text during inspection printing.
A control signal of B is used. Thus, using four gates 93-97 connected in the manner shown in FIG. 14, if one AUDB signal is off, multiplexer 78 gates the highest order digit to print control logic 8 first. , then gate the lowest next digit, then gate the space position code. However, if the IAUDB signal is on, multiplexer 78 will not output any reference digits therefrom, but will only gate the three space position codes to print control logic 8.

This setting of the IAUDB signal (and thereby inhibiting printing of the reference line number) occurs in response to the left margin return of the carrier in response to a code that does not display the line end.

According to those skilled in the art, without departing from the basic concept of the invention,
Various modifications and additions can be made to the device described above.

For example, the type and number of test print instruction codes (and their corresponding test print characters) may vary in different types of systems depending on the objectives and results sought. Additionally, although the above description of test print equipment describes the actual printing of text characters, test print characters, and reference line numbers, this same concept and technique can be applied to any type of operator, including a wide variety of visual display devices. It is equally applicable to outputs that can be read.
