Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic typewriter that makes it possible to print out an easy-to-read document with the ends aligned even when input data exceeds the right hand margin.

As is well known, there are high-end electronic typewriter devices that are equipped with high-performance document editing functions for the purpose of rapid recovery from input errors and flexibility in editing.

Usually, this type of electronic typewriter is equipped with a display device such as a CRT, and an operator corrects or edits a document while looking at the display screen, and prints out the document. On the other hand, this type of electronic typewriter has a function for aligning the end of sentences (justification function) to make printed documents easier to read.
Conventionally, this type of function was performed as long as the data did not exceed the right hand margin, and the only way to do so was to widen the space width and align the ends of sentences. The present invention provides a function to cancel the right hand margin (RHM), widens the space width as long as the input data does not exceed the RHM, and narrows the space width when the input data exceeds the RHM, so that the ends of the sentences are aligned. Our goal is to provide an electronic typewriter that makes this possible.

Hereinafter, the content of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram schematically showing the entire system of an electronic typewriter with a one-line display device according to an embodiment of the present invention.

In the figure, numeral 10 is a keyboard on which character/numeric keys, function keys, etc. are arranged, and key input information from the keyboard 10 is taken into a control section 30 through a keyboard interface and a buffer section 20. The control section 30 decodes the key input information (code), and if it is a function code, performs the corresponding control, and if it is a data code, writes the data code into the memory 40. The memory 40 has a storage capacity for one page of prints, for example.
Of course, this is just an example, and the capacity of the memory 40 may be equivalent to several lines of print. In parallel with this key input operation, the control section 30 reads out one line of data from the memory 40 and supplies it to the display device 60 having a display surface of one line through the CRT drive and interface section 50 for display. . Also, the control section 30
monitors the type of data read from the memory 40 and the data display position of the display device 60, and detects codes such as carriage return (CR) and line feed (LF) as read data, and When the display position enters the right hand margin (RHM), the data for one line is output to the printer 80 through the printer interface unit 70, a print start signal is issued at the same time, and the data for one line is automatically started. Perform printing.

Memory 40 is a floppy disk ●Interface 90
The memory 40 is connected to the floppy disk device 100 through the floppy disk device 100, and when tabulation of, for example, several lines to one page, which is determined by its storage capacity, is completed, the contents of the memory 40 are transferred to the floppy disk device 100. Furthermore, the keyboard 10 is provided with a margin release key, and when the cursor (mark indicating the display position of the next input data) on the display surface of the display device 60 is on RF[M, press the margin release key. The margin is removed (that is, the RHM mark on the display surface is masked), and data can now be entered beyond the margin. FIG. 2 is a detailed diagram of the control unit 30.

Hereinafter, the basic operation of an electronic typewriter with a one-line display device according to an embodiment of the present invention will be explained first, and then the characteristic operation of the present invention will be explained. In FIG. 2, 40 is the number of lines explained in FIG. Alternatively, it is a memory that has a storage capacity of about one page, and indicates that data is stored in the shaded area.

The H point marked on the memory 40 is the memory address where the first data of the line to be displayed on the display device 60 is stored, the P point is the memory address where the next key input data is stored, and the Q point is the end code.

There is a one-to-one correspondence with the character position of 06.

In this format register group 307, each of the above positions is designated by setting the corresponding bit to logic "1". 308 is an address pointer indicating the working address of the display buffer 306 and the format register group 307. 309 is an LHM address register that stores the address of the left hand margin (LHM), and 310 is an SP address that stores the address on the memory 40 of the space code (SP) that has entered the hot zone during data transfer to the display device 60. It is a register.

Reference numeral 311 indicates an RHM address register that stores the address of the right hand margin (RHM).

312 is a data discrimination/control logic circuit that discriminates the type of data transferred from the memory 40 to the display buffer 306 and outputs various control signals.

313 to 316 are state flip-flops set by the output control signal of the data discrimination/control logic circuit 312, the flip-flop 313 is a space (SP) in the hot zone, and the flip-flop 314 is a high-on (-) in the hot zone. , 315 is a carriage return (CR)

Reference numeral 328 denotes a printer output control circuit that controls data transfer between the reprint buffer 305 and the printer 80 according to instructions from a print start signal and a print end signal.

329 is an input code determination control circuit that determines the key input code and divides it into data and function code, transfers the data to the memory 40, and outputs the function code to a desired location of the device as a control signal.

FIG. 3 shows a flowchart for explaining the operation of FIG. 2.

Now, assume that the memory 40 contains data in the shaded area as an initial state. As explained above, the address register 301 stores the P point address of the memory 40, similarly the address register 302 stores the Q point address, and the address register 303 stores the H point address. At this time, display buffer 30
6 stores the contents of the memory 40 after the H point address, which are taken into the display device 60 together with each piece of information in the format register group 307 and displayed on its display screen. Figure 8A shows an example of the format display, where 4 represents the left hand margin, @ represents the right hand margin, (c) represents the tab set position, 4 represents the hot zone range, and (e) represents the cursor. There is. Now, when a new input is made from the keyboard 10 and the key input code is determined to be data by the input code determination control circuit 329, the data is stored in the address register 301.
It is written to the P point address of the memory 40 specified by . Thereafter, the address register 301 is incremented by 1 by the arithmetic unit 319. Along with this key input operation, the display buffer 306 is rewritten.

In this case, first, data transfer preparation processing is executed as follows. That is, the H point address of address register 303 is moved to working address register 304, and the contents of display buffer 306 are cleared. At the same time, the contents of LHM address register 309 are set in address pointer 308. Thereafter, the state of the LF display flip-flop 316 is checked, and if it has been reset, the format register group 307
registers 4 to 7 are cleared, and the flip-flop 31
3 to 318 are reset. On the other hand, if the beach display flip-flop 316 is set, data discrimination/
Under the control of the control logic circuit 312, the address pointer 308 is incremented until it detects "1" in the line tail register 7 of the register group 307, and the address pointer 308 is aligned by line feed, and then, Similarly to the case where the display flip-flop 316 is reset, registers 4 to 7 of the format register group 307 are cleared and flip-flops 313 to 318 are reset. This completes the data transfer preparation process, and the contents of the address in the memory 40 specified by the working address register 304 (that is, the contents of the H point address) are read out, and the address pointer 308
is written to the display buffer 306 address specified by . In parallel with this data transfer from memory 40 to display buffer 306, the transferred data is discriminated by data discrimination/control logic circuit 312, and the following processing is performed depending on the type.

That is, if it is character/numeric/symbol data, the address pointer 308 is incremented by 1 to prepare for the next data transfer.If it is a space code, the status flip-flop 313 is set only when the hot zone is entered. , the working address register 30 at that time
4 is transferred to the space address register 310. The address pointer 308 is incremented by 1 regardless of whether it is inside or outside the hot zone. In the case of the Haiphong code, the status flip-flop 314 is set only when the hot zone is entered. The address pointer 308 is incremented by 1 regardless of whether it is inside or outside the hot zone, as in the case of the space j code. In the case of a carriage return code, the status flip-flop 315 is set regardless of whether it is inside or outside the hot zone. or,
In this case, address pointer 308 is not incremented.
In the case of a line feed code, the state flip-flop 316 is set, and 6'F5 is set in the bit of register 7 in the format register group 307 specified by the address pointer 308 at that time. Address pointer 308 is not incremented. Predetermined processing is similarly performed for other codes. When the margin release key is not pressed, the status flip-flop 317 compares the contents of the address pointer 308 and the RHM address register 311 with the comparison circuit 323, and is set when the two match. On the other hand, when the margin release key is pressed, the setting operation of this state flip-flop 317 is prohibited, and is then set only after a carriage return code or space code is detected, for example. FIGS. 5 and 6 show these processes in a table. Note that the hot zone area can be detected by accessing the hot zone designation register 3 in the format register group 307 with the address pointer 308 and checking whether the designated bit is set to ゜゜1゛.

The read signal from this hot zone designation register is
The discrimination signal of the data discrimination/control logic circuit 312 is individually ANDed, and the state flip-flops 313 and
314 set input, and space address register 3
10 data latch signals. As described above, one piece of data is transferred from the memory 40 to the display buffer 306, and if that data is not an end code,
The working address register 304 is incremented by 1 by the arithmetic unit 320 .

At this time, if the flip-flops 313 to 317 all remain in the reset state, the contents of the next address in the memory 40 specified by the address register 304 are read out, and this is the address pointer 308 (the pointer is the sixth
(which has already been updated in the manner shown) is written to the address of display buffer 306 specified by . This data transfer is repeated while state flip-flops 314-317 are reset, and display buffer 306
will be rewritten. During this time, the comparison circuit 321 compares the address registers 301 and 304, and if the contents of the two match, it sends out a match signal. This match signal sets state flip-flop 318. In other words, all data transfer from the memory 40 to the display buffer 306 is completed before the right hand margin is reached, and the transferred data does not include codes such as carriage return and line feed. Even if a Haiphong code is included, it means you are outside the hot zone. When the state flip-flop 318 is set, the Q point address of the address register 302 is transferred to the working address register 304, and the end code is read from the memory 40.

When the data discrimination/control logic circuit 312 detects this end code, the operation of transferring data from the memory 40 to the display buffer 306 is not executed until the next key input is performed. During this time, the contents of display buffer 306 will continue to be displayed by display device 60. This is a case where the end code of the memory 40 is stored in advance, but if the end code is not used,
By setting the flip-flop 318, the data transfer operation from the memory 40 to the display buffer 306 is stopped to prepare for the next key input. On the other hand, the match signal from the comparison circuit 321 is applied to the cursor register 5 of the format register group 307, and the bit specified by the address pointer 308 at that time is set to ゜゜1゛.

In other words, this indicates the display position of the next key input data. In this way, when the next key input is performed and it is data, the data is stored at the address in the memory 40 specified by the address register 301, and at the same time, the display buffer 306 is rewritten in the same manner as before. is executed again, and the rewritten data is transferred to the display device 60 and displayed. FIG. 8B shows an example of the display. Data input from keyboard 10 and display buffer 306 based on this
The data rewriting operation progresses, and the flip-flop 3
Suppose that 13 to 316 reach the right hand margin position while remaining in the reset state.

In other words, this means that you have reached the right hand margin with no spaces in the hot zone. In this case, the contents of the address pointer 308 and the RHM address register 311 match, and a match signal is detected from the comparison circuit 323 on the output line 11. As a result, in normal operation, the RHM flip-flop 317 is set through the AND gate G1'2 and the OR gate G14, alerting the operator to the hyphenation, and stopping the device until another key input is made. On the other hand, when the cursor is at the right hand margin position, the keyboard 10
Suppose you press the upper margin release key. in this case,
As before, set the margin release code to memory 40.
At this time, the data discrimination/control logic circuit 312 determines that the transferred data is a margin release code and sets the address of the margin mask register 6 in the format register group 307. Pointer 308 (RHM
The bit ゜゜1゛ indicated by (indicating the position) is set. As a result, inverter gate Gll prohibits energization of AND gate GlO, and display device 60
The margin mark on the display surface is erased. At the same time, inverter gate Gll also inhibits activation of AND gate Gl2, and RHM flip-flop 317 remains reset. Therefore, data can still be input using the keyboard 10. 9A to 9C show examples of the display when the margin release key is pressed, and 1φ is the margin release display JZ. J indicates input data after the margin release key is pressed. Data is input to the right of the right hand margin, and the contents of the address pointer 308 are transferred to the RHM address register 31.
If it becomes greater than that of 1, the comparison circuit 323 will send out a ゜゜1゛ signal at the output 12.

Therefore, when the space key is pressed thereafter, the AND gate Gl3 is activated and the RHM flip-flop 317 is set for the first time. Note that the reset of the RHM flip-flop 317 is performed by printing out one line, which will be described later, and the next line of data is stored in the memory 4.
0 to the display buffer 306, the flip-flops 313-316 are reset prior to the operation. Next, the printing operation will be explained. This is done automatically when any of the flip-flops 314-317 is set, and the apparatus switches to print mode. First, a case where the Haiphong display flip-flop 314 is set will be described.

From FIG. 4, the flip-flop 314 is set when one line of key input advances to the hot zone and a hyphen is added for a line break. In that case, the contents of that line are immediately printed out, and the display device 60 displays the key input data of the next line. Its operation is as follows. When the set state of the flip-flop 314 is detected, the address register 303 is set again.
The H point address is the working address register 304.
The contents of the address in the memory 40 indicated by the address register 304 are transferred to the reprint buffer 305 through the multiplexer 324. Writing to the print buffer 305 is performed at the timing of the input strobe. Note that data transfer to the display buffer 306 is prohibited in this print mode. After that, the working address register 304 is transferred to the arithmetic unit 320.
+1 is added. The contents of the working address register 304 are compared with the contents of the address register 301 by a comparison circuit 321, and data transfer to the print buffer 305 is repeated until the two match. When the address registers 301 and 304 match and the data transfer from the memory 40 to the print buffer 305 is completed, the haiphon detection circuit 324 detects the haiphon code.

Also, at this time, the flip-flop 314 is in a set state. Therefore, the switching signal D is applied to the multiplexer 325. As a result, multiplexer 325 selects a preset carriage return code (CR code) and transfers it to print buffer 305. In other words, in the print buffer 305, one line of data from point H to point P (point P is a point that moves each time a new key input is given) in the memory 40 has an additional CR code.
It is added and stored. After that, the contents of the working address register 304 at that time are changed to the address register 304.
Moved to 3. That is, a new H point address is registered. On the other hand, the CR code selected by the multiplexer 325 and transferred to the print buffer 305 is detected by the print start instruction circuit 326, and as a result, a print start signal is transmitted from the instruction circuit 326 to the printer output control circuit 305.
28.

When the printer output control circuit 328 receives the print start signal, it issues an output strobe signal to the print buffer 305, reads the data stored in the print buffer 305 sequentially while checking the ready signal of the printer 80, and outputs the data to the printer 80. In this way, when the last data, that is, the CR code is read out from the print buffer 305, the CR code is output to the printer 80 and simultaneously detected by the print end instruction circuit 327, and as a result, the instruction circuit 327 prints the A termination signal is provided to printer output control circuit 328. Upon receiving this print end signal, the printer output control circuit 328 stops the output strobe to the print buffer 305, thereby completing reading data from the reprint buffer 305.
During this time, the printer 80 sequentially prints out the data given through the print output control circuit 328, and
When a code is detected, a carriage return operation is performed,
It prepares for the next printing line. That is, once one line of data is transferred from the memory 40 to the print buffer 305, the print operation for one line is performed independently of the display display operation under the control of the print output control circuit 328. It will be destroyed. This is common to all subsequent print operations. Next, state flip-flop 3
The case where 15 or 316 is set will be explained.

In this case as well, the contents of the address register 303 are transferred to the working address register 304, and the contents of the address in the memory 40 indicated by the address register 304 are transferred to the print buffer 305. the. After that, the address register 304 is incremented by 1, and the address register 301
The transfer from the memory 40 to the print buffer 305 is repeated in synchronization with the input strobe until 304 and 304 match, and when they match, the contents of the register 304 at that time are transferred to the address register 303. These operations are the same as when state flip-flop 314 is set. The print operation is performed using the CR read out from the memory 40.
code or LF code as it is to the multiplexer 325
This is detected by the print start instruction circuit 326, and a print start signal is issued to the printer output control circuit 328, thereby starting the print. Next, state flip-flop 317 is set, and this time flip-flop 313
The case where is also set will be explained.

An example of the display at this time is shown in FIG. 7C. In other words, this is the case when the margin release key is not pressed. In this case, the data up to the space closest to the write hand margin (RHM) is printed out, and the data after that is newly displayed on the display device. That will happen. Its operation is as follows. When the set state of the state flip-flops 313 and 317 is detected, the contents of the address register 303 are transferred to the working address register 304, and the contents of the address in the memory 40 indicated by the address register 304 are printed, as before. It is transferred to buffer 305. After that, the working address register 304 is incremented by 1. At this time, as is clear from FIG. 4, the space address register 310
stores the address on the memory 40 of the space closest to the RHM. When the working address register 304 is incremented by 1, its contents are compared with the contents of the space address register 310 by the comparison circuit 322,
from memory 40 to print buffer 3 until both match.
Data transfer to 05 is repeated. When the address registers 304 and 310 match, a match signal is output from the comparison circuit 322, and the data transfer to the nearest space of the RHM is completed. At this time, the match signal E switches the multiplexer 325, and The CR code is added in the same way as when 314 is set. When this CR code is detected by the print start circuit 326, the reprint operation is started. On the other hand, working address register 304
is incremented by 1 by the arithmetic unit, and its contents are stored in the address register 30.
3 will be newly registered. Therefore, in subsequent data transfer to the display buffer 306, the next data in the space closest to the RHM is read out, and the display buffer 306 is rewritten. The same applies when the margin release key is pressed and data is input to the right of RHM, and then the flip-flops 313 and 317 are set by the space code. FIG. 7 shows a specific example of the configuration of the data discrimination/control logic circuit 312.

As described above, the data discrimination/control logic circuit 312 has the function of directly transferring the data read from the memory 40 to the display buffer 306, the function of discriminating the transfer data, and the function of determining the address pointer 30 based on the discrimination result.
It has the function of advancing 8. Block 601 is a section that outputs input data from memory 40 as is to display buffer 306 and at the same time discriminates the data, and is comprised of a so-called decoder matrix. The space (S
P), Haiphong (-), Carriage Return (CR)
, line feed (LF) are set inputs to the state flip-flops 313 to 316 in FIG. 2, and the margin release determination output is input to the margin mask register 6. 602 is a flip-flop, 603 is a clock pulse generator, and 604 is a ±1 circuit. The ±1 circuit 604 is the address pointer 3 in FIG.
The decoder matrix 601 increments the address pointer 308 by +1 when characters, numbers, and symbols are detected, and -1 when the back base (BSP) is detected.

Note that the strobe signal is issued every time one data transfer is performed, and the above-mentioned +1 or -1 is executed at the timing of generation of the strobe signal. Decoder matrix 6
When a tab is detected at 01, flip-flop 602 is set. As a result, the clock pulse generator 603
The clock output of the address pointer 308 is applied to the power output circuit 1, and during this time, the address pointer 308 continues to increment. The address pointer 308 advances by one step, and the format register group 30
When 66r' is sent from the tab register 2 of No. 7, the flip-flop 602 is reset, thereby stopping the sending of the clock pulse, that is, the incrementing of the address pointer 308. At this time, the address pointer 308 is pointing to the target tab position. Similarly, when the state flip-flop 316 is set, the clock pulse generator 603, ±1
The circuit 604 increments the address pointer 308, and stops the increment when ゜゜1゛ is sent out. That is, this is the process of positioning the address pointer 308 by line feed as described above. Decoder ● ±1 circuit 60 if carriage return (CR), line feed (LF), half line feed (HLF), half reverse line feed (HRLF), margin release, or end code is detected in matrix 601
Prohibit operation 4. This is easily understood from the table in FIG. The basic operation of the word processor targeted by the present invention has been explained above.According to the present invention, in such a word processor, input data is
Even when RHM is exceeded, as well as when it does not exceed M, justification can be performed as follows.

Normally, the SP amount for justification is calculated as follows.

However, for simplicity, 1160 inches is assumed to be the minimum SP unit. (b) Let the remaining distance from the end character of the line to the RHM be x/60 inches.

(b) Let the number of SPs included in that line be y.

(c) Let x+y=z and the remainder be a. (d) From the last SP in the row to the a-th SP, z+1/6
The SP spacing is increased by 0 inches, and the SP spacing is increased by z/60 for the a+1st to yth SPs.

If input exceeds RHM, x may become negative, but in that case, counting from the first SP of the row up to the a-th is z+1/60 inch, and from the a+1-th to the y-th Justification can be performed by decreasing the SP spacing by z/60 inches up to SP.

In FIG. 2, 330 to 334 are the characteristic configurations of the present invention, 330 is a working counter, and 331 is the above (c).
332 is a register that stores the quotient of the processing of
Counters 333 and 334 are state flip-flops.

FIG. 4 shows a flowchart for explaining the justification process of the present invention, and FIG. 10 shows a display example. Now, when the data transfer to the display buffer 306 is completed, the justification mode (
JUS mode), and at the time of justification, the flowchart shown in FIG. 4 is proceeded to.

Here, if neither of the flip-flops 313, 314 is set, the process directly proceeds to step 4. If either flip-flop 313 or 314 is set, state flip-flop 333 is set to 1,
After setting the counter 330 to 0, search for the line tail. Depending on the state of the flip-flop 334, which indicates whether the margin release key is pressed, it is determined whether the line tail is inside or outside the RHM, and how much is left to the RHM or how much is beyond the RHM. Count the number of animals. The line tail is shown graphically for each data as shown in Figure 10, but if the line tail is SP, the number of SP included in that line is shown as SP.
Subtract 1 from the P counter 332, and the line tail is R.
Counter 3 depending on whether it is inside or outside the HM.
Adjust the numbers by adding or subtracting 30. This is done because SP of the line tail is converted to CR when output to the printer 80. Line tail is R
The total SP number is obtained by adding or subtracting the contents of the counter 330 to the SP counter 332 depending on whether it is inside or outside the HM. Now, if we are printing at a pica pitch (1110 inches), by multiplying the register 331 by 6, the total S
The amount of P appears. Divide the contents of the counter 332 by the contents of the register 331, put the quotient in the register 331 and the remainder in the SP counter 332, and go to step 4. When transferring data to the printer 80, when SP comes, the print output control circuit 328 refers to the flip-flop 333, and if it is 1.
If so, transfer the ESC code + 8-bit space amount and the space amount divided into z bytes. 2 and 7 actually constitute a part of a microcomputer, for example, and it goes without saying that the operation sequence of each part described so far is controlled by a program.

FIG. 3 and FIG. 4 collectively represent the operation flow. As described above, the electronic typewriter of the present invention not only expands the space width and aligns the endings of sentences, but also
It is possible to narrow the space width and align the ends of sentences, and it is possible to print out a document that is easier to read than the conventional one.
