Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an electronic typewriter that performs printing through electronic storage and control, and in particular, stores line format data such as left margin, right margin, tab stop, etc. in a memory, reads it out, and prints the line accordingly. The present invention relates to a printing method using an electronic typewriter that can print on a paper.

[Conventional technology]

Conventionally, this type of electronic typewriter has been used to store edited text on an external floppy disk drive, while also storing line format data such as the above, and pages for one page such as vertical tabs, page ends, jumps, etc. The format data is stored in the internal memory (RAM), and the text read from the floppy disk drive device can be automatically printed based on the stored line format and page format. Are known.

[Problem to be solved by the invention]

However, the conventional one has a line format for one line (for example, the left margin is 4 and the right margin is 48).
and the page format for one page (for example, vertical tab stop on the 10th line, vertical tab stop on the 22nd line)
(such as automatically discharging paper at the end of a page) are set and stored separately without any relation to each other, so one line can be automatically changed to another line format, After that, the operator automatically prints based on the changed line format, or automatically prints the left column for one page with the left margin set to 4 and right margin set to 24, and then the operator changes the line format settings again. Therefore, it was not possible to set the left margin to 38 and the right margin to 58 and automatically print the right column as originally set.

[Means to solve the problem]

The present invention has made it possible to easily realize such a thing, and its characteristics are that line format data is divided into multiple sets and stored in memory, and one-page format data such as vertical tabs, page ends, jumps, etc. When storing page format data about the page format data in the memory, a set number selected from among the plurality of sets of line format data is stored in the memory together with line feed point data indicating the position of the desired line. However, when reading the page format data, the line format data of the selected set number is read out when printing the arbitrary line, and the data is printed accordingly.

[Effect]

Therefore, according to the present invention, specifically, one page can be printed in the manner shown in FIG. 7, for example. That is, in this figure, one broken line indicates one line to be printed, and first, the first and second lines are printed according to the line format LF ₁ of group number 1 with a left margin of 4 and a right margin of 58. After printing the eyes, jump (JP) to skip one line (leave the third line blank), perform vertical tab stop (TS), and from there set the left margin to 4 and the right margin to 24, group number 2. After printing the left column of 9 lines from the 4th line to the 12th line according to the line format LF ₂ , jump (JP), return to the 4th line, tab stop (TS), From there, after printing the right column of 9 lines from the 4th line to the 12th line according to the line format LF 3 of set number ₃ with a left margin of 38 and a right margin of 58, the page end ( PE) can be used to stop the line feed or automatically eject paper.

writing operation, display operation of the display device 4,
All operations such as printing, collect, space, backspace, paper feed, etc. by the print control device 34 are performed under the control of the system control device 33. The system control device 33 is divided into a main control section and a format control section controlled by the main control section, and includes a circuit shown in FIG. Therefore, all the circuits shown in FIG. 4 that control the line feed operation are included in the format control section.
In these figures, signal lines with filled circles indicate that signals are input from other circuits in both figures, and signal lines with unfilled circles indicate that signals are input from the main control unit. Indicates that a signal is being input. Also, the same signal is represented by the same single alphanumeric character. Line format data (hereinafter simply referred to as line format) and page format data (also referred to as page format) are divided into groups and divided into groups for each group number and, in each case, for each set point. It is stored in the memory (RAM) shown in the figure. Figure 5 shows the line format of a certain set, for example, set number 1 determined by pressing the number key ``1'' and the phrase key 27 at the same time, and Figure 6 shows the line format of a certain set, for example ``8''. The storage mode of the page format of group number 8 determined by pressing the number keys and the phrase key 27 at the same time is shown. Here, line columns L ₁ , L ₂ , L _{3 .} . . and page columns P ₁ , P ₂ , P _{3 .} . . are stored separately for each column in one set of line formats and one set of page formats. Which indicates that. Also, line index data is
Indexes such as margins determined within one line, and page index data are:
In each case, each index of a vertical tab stop or the like determined within a page is represented by a two-letter alphanumeric symbol, and the meaning of the symbol is as follows. LM...Left margin HZ...Hot zone (range where carrier 5 can be returned automatically, for example) RM...Right margin TB...Tab DT...Decimal tab VT...Vertical line drawing tab LF...Line format JP...Jump TS...Vertical tab stop PE...Page end Additionally, space feed point data refers to a specific print position (digit) within one line, and line feed point data refers to a specific print position (digit) within one page. The position (row) in the line feed direction is shown.
For example, in FIG. 5, the contents of line column _L1 are left margin (LM), and the value 4 is stored in its space feed point data. Furthermore, link data refers to data such as line formats that are read out in linkage with page index data. For example, in the case of page column P ₁ , the page index LF instructs to link line formats, and the line format to be linked is group number 1.
The line format is LF ₁ , and the content is to be printed according to this LF ₁ from the line specified by the line feed point data (for example, the first line in FIG. 7). Therefore, the following describes ``line format setting storage operation'', ``page format setting storage operation'', ``line format readout operation'', ``page format readout operation'', and ``line feed based on page format''. "Operation" will be described in detail with reference to FIGS. 3 and 4. "Line format setting storage operation" (1) Set the operation mode selector 30 to format mode, and press any one of the number keys 1 to 7. for example,
To set the line format for group number 1, press the number key "1". Then, use space or backspace to move the carrier 5 to the desired position where you want to set the left margin (LM), right margin (RM), tab (TB), etc., and then press the left margin key 14, right margin key 15, tab set key. 16, etc., and finally the entry key 26, the line format of group number 1 is stored in column order as follows. (2) The group number (numeric data) A corresponding to the pressed number key is entered into the register 51, and after a short delay, the pulse B is input and the group number A is latched into the register 51. The set number A is passed through the selection circuit 52, and the address designation data C is passed through the selection circuits 53 and 54.
At the same time, the position data D (in this case, the space feed point data) is also entered into the memory 50 via the memory 50, and is stored in the memory 50 in the manner shown in FIG. The selection circuit 53 passes the address designation data C when the format mode signal E is input. Note that the left margin (LM), hot zone (HZ), and right margin (RM) are preferably stored in the order of line columns L ₁ , L ₂ , and L ₃ . "Page format setting storage operation" (1) Set the operation mode selector 30 to format mode, and press any one of the three number keys 8, 9, and 0. For example, to set the page format for set number 8, press the number key "8". Then, if you want to move the carrier 5 to a desired line by linefeeding it in the forward direction or in the reverse direction, and linking the line format of any set number among the line formats set as described above, Press the number key and phrase key 27 at the same time. For example, when linking the line format LF ₁ of set number 1, the number key "1" and the phrase key 27 are pressed at the same time. Also, to insert a jump (JP), press the J key 35 of the character keys 9 on any line, to insert a page end (PE), press the E key 36, and to insert a vertical tab stop (TS), press the E key 36. , press the code key 28 and tab key 17 at the same time to enter vertical tab mode, then press the tab set key 16
Press. (2) Enter data A, B, C, D (line feed point data in this case) in the same way as above,
The data is stored in the memory 50 in the manner shown in FIG. Note that the first page column _P1 must always contain the line format (LF). Other page columns are free. "Reading operation of line format" (1) Set the operation mode selector 30 to print mode, and press the numeric key of the group number of the line format you want to read and the phrase key 27.
Press and at the same time. For example, if you want to read line format LF ₁ of set number 1, enter "1".
Press the number keys and phrase key 27 at the same time. (2) As in the case of storage described above, the set number A is latched in the register 51, the pulse B passes through the OR 55 and enters the column counter 56, and the column counter 56 is set to "1" by the predetermined value setting circuit 57. be done. On the other hand, the pulse B passes through the AND circuit 58 and the OR circuit 59 to operate the buffer write control circuit 60, and its output F becomes HIGH.
From this, signals G representing 1, 2, 3, etc. are sequentially outputted and passed through the selection circuit 54 to the memory 50.
A pulse is output from one data line a for group number A in synchronization with this. As a result, by pressing any number key from 1 to 7, the line format of the set number specified as above is read out from the memory 50 in column order, and is transferred to the line format buffer 62 via the gate circuit 61. are stored sequentially. When the total number of line columns is reached, the output F becomes LOW. The line format of the designated set number stored in the line format buffer 62 in this way is transferred to the carrier 5 by the main control section.
It is read out at any time in accordance with the operation, and is automatically printed accordingly. "Page format reading operation" (1) Set the operation mode selector 30 to print mode, and press the numeric key of the set number of the page format you want to read and the phrase key 27.
Press and at the same time. For example, if you want to read the page format of set number 8, you press the number key "8" and the phrase key 27 at the same time. (2) The set number A is latched in the register 51, and the column counter 56 is set to "1". At this time, signal a becomes HIGH, but the output of AND circuit 58 does not become HIGH, so
Buffer write control circuit 60 does not operate. The signal a passes through an AND circuit 63 to which the print mode signal H is input, and further through an AND circuit 64 to open a gate circuit 65. Therefore, first, the first page column P ₁
The data is read out from the memory 50, and the page index data therein is decoded by the decoder. 1st page column P ₁
Since the index normally contains the line format (LF), the decoder 66
A signal is output from the LF terminal, and the AND circuit 67
The signal I is delayed by the delay circuit 68 and becomes the signal I, which passes through the AND circuit 59 and activates the buffer write control circuit 60. Prior to this, the print mode signal H, the signal a, and the pulse B are input to the AND circuit 69, and the flip-flop 70 is set.
The output of the flip-flop 70 is input to the AND circuit 67. This flip-flop 70
is reset by signal I from delay circuit 68. On the other hand, link data J of page column P ₁ output from gate circuit 65 enters register 71 . At this time, the register 71 is set by the output K of the AND circuit 72 (the memory output will be described later), and the register 71 is also set by the selection circuit 52.
is the output L of the add circuit 73 which receives the output F.
The line format of the group number corresponding to the link data J (LF ₁ in FIG. 6) is read out from the memory 50 in line column order and is stored in the line format buffer 62. Stored. Furthermore, the line feed point data of page column P ₁ that has passed through the gate circuit 65 is latched in the register 74, and the fourth point data is passed through the comparison circuit 75.
It is compared with line feed point data M, which will be described later, which is output from the circuit shown in the figure. Comparison circuit 75
A comparison result signal N indicating the magnitude of the difference is sent to the main control section. Further, the coincidence signal O from the comparator circuit 75 enters the AND circuit 72 and is delayed by the delay circuit 76 before being outputted to the line format LF ₁
A flip-flop 78 is set through an AND circuit 77 to which is input. The output of flip-flop 78 is input to AND circuit 72. Since the register 74 is set by the delay signal from the delay circuit 76, the AND circuit 72
outputs the signal K with a delay after outputting the coincidence signal O. Therefore, in the case of the first page column _P1 , its line feed point data matches the line feed point data M from the circuit of FIG. , the line format LF ₁ of group number 1 to be linked is read out from the memory 50,
The line format is stored in the line format buffer 62, and the main control section controls the space operation of the carrier 5 by referring to the stored line format _LF1 from the matched line as described above. Storing in the line format buffer 62 continues until a new line format is received. The same thing is done for other page columns whose indexes include line formats (LF). When the jump (JP), vertical tab stop (TS), and page end (PE) are also decoded by the decoder 66, signals are output from the respective terminals. "Line feed operation based on page format" This is performed in conjunction with the above-mentioned "page format read operation." Line feed operation is normal, jump (JP), vertical tab stop (TS), and page end (PE).
Each case is different, and each case will be explained using the page format shown in FIG. 6 as an example. Note that this example page format is
This corresponds to the printing example shown in Fig. 7 mentioned above, and the line feed point data of page column P ₁ is 1, that of page column P ₂ is 2, and the page column P 1 is 1.
P ₃ and P ₄ are the same 4, page column P ₅ is 12, page column P ₆ and P ₇ are the same 4, page column
P ₈ is 12. (1) Normal case In FIG. 4, data P indicating the line feed setting value (set by the line feed selector 32 in FIG. 1) is input from the main control section to the selection circuit 100, and is input to the line feed counter 101. This line feed counter 101 has a gate circuit 102.
The clock pulses from the pulse generator 103 passing through the line feed data P are counted with reference to the line feed data P. In addition, line feed counter 10
1 is the line feed execution signal R from the main control section
Set by. Clock pulse Q passing through gate circuit 102
is also sent to the main control section, while the zero detection circuit 1
When it is detected at step 03 that the output of the line feed counter 101 has become zero, the gate circuit 102 is closed, thereby performing normal line feed operation. Further, the clock pulse Q enters a count direction control circuit 104 to which a count direction instruction signal S from the main control section is input, and is counted up or down by a line feed counter 105. The output of this counter 105 is input to the comparison circuit 75 in FIG. 3 as the line feed point data M, and is compared with the line feed point data related to the page format. In the case of page column P ₁ , when the line feed point data matches M, the line format LF ₁ of set number 1 is read out as described above and stored in the line format buffer 62. A space operation is performed with reference to the data, and the first and second lines in FIG. 7 are printed. In FIG. 3, when the comparison circuit 75 outputs the coincidence signal O as described above, it enters the pulse forming circuit 79 in the same figure and is outputted to the column counter 5.
Only one 6 is counted up. This count-up operation is performed by the buffer write control circuit 60.
Since the signal F is input to the pulse forming circuit 79, the buffer write control circuit 60
is prohibited during operation. In this way, page column _P2 is read out, the jump signal JP is output from the decoder 66, and the line feed point data is latched into the register 74. (2) In the case of jump (JP) As shown above, the jump signal is sent from the decoder 66.
When JP is output, flip-flop 106 in FIG. 4 is set. When the line feed point data M from the line feed point counter 105 matches the line feed point data of page column P ₂ and a match signal O is output from the comparison circuit 75, the match signal O is output from the fourth column P2. Flip-flop 108 is set through AND circuit 107 in the figure. The output of the flip-flop 108 enters an AND circuit 109 which receives a carrier return signal T from the main control section. When this carrier return signal T is input to the AND circuit 109, its output passes through the OR circuit 110 to the selection circuit 100, and further passes through the OR circuit 111 to the line feed counter 101. The counter 101 is set to the count value set by the maximum value setting circuit 112. At the same time, flip-flop 108 is reset and flip-flop 113 is set. Then, the pulse Q is output from the gate circuit 102.
is continuously output, and the line feed operation continues. After that, when the line feed point data M from the line feed counter 105 matches the line feed point data of page column P ₃ and a match signal O is output from the comparator circuit 75, it is displayed as shown in FIG. Pulse forming circuit 79 inside
Then, the line format LF ₂ of set number 2 is read out in the same manner as above. Further, this match signal O passes through an AND circuit 114 to reset the flip-flop 113, and further passes through an OR circuit 115 to reset the counter 101. Thus, the gate circuit 102 is closed, blocking the passage of the pulse Q and stopping the line feed operation. That is, in FIG. 7, the second to third lines are skipped and jump to the fourth line.
At this time, flip-flop 106 is reset. Next, Hage column P ₄ is read out and the third
In the figure, when the vertical tab stop signal TS is output from the decoder 66, it is input to the AND circuit 80. A match signal O is also input to the AND circuit 80. Since the line feed point data of page columns P ₃ and P ₄ are the same as described above, the output of the AND circuit 80 at this time enters the pulse forming circuit 79 and is input to the column counter 56.
is counted up, and the delay circuit 7
6 to register 74. As a result, page column _P5 is read out, and the same operation as above is performed. (3) Vertical Tab Stop (TS) The case of page column P ₄ is as described above, so here we will discuss the case where a vertical tab command is issued midway. When there is a vertical tab command, the tab execution signal V from the main control section sets the flip-flop 117 in FIG. 4, and the output of the flip-flop 117 enters the AND circuit 116. In this state, the vertical tab stop signal TS is output from the decoder 66 in FIG.
16, and when a match signal O is input thereto, the output of this AND circuit 116 is output to OR circuit 1.
15 to reset the line feed counter 101. This closes the gate circuit 102 and stops the line feed operation. At this time, flip-flop 117 is reset. (4) In the case of page end (PE) When the page end signal PE is output from the decoder 66, the flip-flop 11 in FIG.
8 is set, and the discrimination circuit 119
Then, link data J is input from the gate circuit 65 in FIG. The discrimination circuit 119 discriminates whether link data J is "1" or "0", that is, whether link data J is present or not. When the match signal O enters the AND circuit 120 when it is "1", the line feed counter 101
is set to the maximum value in the same way as above, and the paper is automatically ejected, for example. The line feed point data W output from the AND circuit 120 enters the OR circuit 55 in FIG. 3, and the column counter 56 is set again. When it is "0", the line feed stops at the matched position.

【Effect of the invention】

As described in detail above, according to the present invention, by specifying and storing an arbitrary group number among a plurality of pre-stored line formats at the time of page formatting, For example, after setting the left margin to 4 and the right margin to 24 and automatically printing the left column for a certain page, the operator For example, set the left margin to 38 and the right margin to 58 as originally set without changing the line format settings again.
Documents in various formats, such as automatically printing the right column as a document, can be easily printed without requiring the troublesome work of changing formats as in the past.
