Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a document processing device, and is characterized by a document processing device capable of automatically adding an underline to a desired location when printing data input from a keyboard. It is related to.

PRIOR ART A document processing device capable of automatic underlining as described above is already known. However, in conventional document processing devices, when auto-underlining is commanded, it goes without saying that underlining is actually automatically performed from that position in the printing device.
If a display device or the like is provided, the underline is also displayed on this display device to inform the operator of the underlined location, and other characters are displayed on the display means. - Symbols indicating the underline start and end positions were not displayed along with the symbols and print control symbols. Further, the underline start command means for commanding the start of underlining and the underline end command means for commanding the end of underline are the same. For example, the alternate switch was activated according to the operation of the underline key, and when the underline key was pressed first, underline start data was input, and then the underline key was pressed. The system was configured so that when the data was entered, underlined data was input.

Therefore, the underline start data and the underline end data can only be input alternately; for example, if only the underline start data or the underline end data is input continuously multiple times, these data could not be entered in any order.

For this reason, in the past, if it was discovered that there was an error in the position where an underline should be added after a key input was made in auto-underline mode, the erroneous part would be marked with an underline or an underline. I had no choice but to rekey the keystrokes without using the keypad, and correcting the underline position was troublesome.

Purpose of the Invention The present invention has been made against the background of the above-mentioned circumstances to provide a document processing device that can easily change the position at which an underline is automatically added.

Structure of the Invention The structural features of the present invention include a character key for inputting character data representing characters and symbols, and an underline set key for inputting an underline start command for commanding the start of an underline. A keyboard equipped with an underline reset key for inputting an underline end command for commanding the end of an underline, and a memory for storing character data input by the keyboard, an underline start command, and an underline end command. means, an underline flag that is set by an underline start command and reset by an underline end command, and an underline flag that is set when the underline start command is read from the memory means, and an underline flag that is set when the underline start command is read from the memory means. When the underline start command is read out from the memory means again in the state where the underline flag is read out from the memory means, the underline flag is kept set, and when the underline end command is read out from the memory means, the underline flag is reset. and flag control means for maintaining the reset state of the underline flag when the underline end command is read out again from the memory means while the underline flag has been reset, and character data read from the memory means. The present invention is provided with printing means for printing with an underline when the underline flag is set and printing without the underline when the underline flag is reset.

Effects of the Invention As described above, according to the document processing apparatus of the present invention, the underline start command and the underline end command are stored together with the character data in the memory means, and the underline start command is read out from the memory means. Since the underline is printed based on the underline flag that is set by and reset by the underline end command, the underline start command and underline end command can be deleted or deleted in the same way as normal character data modification. This allows you to easily change the part that is automatically underlined during printing.

Further, when the underline start command is read out with the underline flag set by the flag control means, the set state of the underline flag is maintained, and the underline flag is reset with the underline flag being reset. The underline flag remains reset when the command is read, so if there is an error in either the underline start position or end position,
If you want to correct the wrong start or end position by expanding the underlined range,
By simply inserting an underline start command or underline end command, you can expand the range of underlining, and you can omit the operation of deleting the underline start command or underline end command that is in the wrong position, making it easier to change. It becomes even easier.

Embodiments Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In this embodiment, the document processing apparatus of the present invention is applied to a typewriter.

FIG. 1 shows an external view of a battery-powered portable typewriter that is an embodiment of the present invention. As is clear from this figure, the typewriter of this embodiment is equipped with a keyboard 10 at the front.
0 is alpha key 12, number key 14,
In addition to the various keys that a normal typewriter has, such as the space bar 16 and line feed key 18, there are also a code key 20, a left cursor key 22, a right cursor key 24, a delete key 26, an insert key 28, and an under key. A line set key 30, an underline reset key 32, etc. are arranged. The keyboard 10 is further provided with a 15-digit liquid crystal display 40, which can display a certain number of characters, symbols, etc. entered by the keys.

In addition to these, the keyboard 10 is also provided with a line pitch selection switch 42, a first mode selection switch 44, and a second mode selection switch 46. The line pitch selection switch 42 is a switch for selecting the print line pitch, and the first mode selection switch 44 is a switch for selecting the operating mode of the typewriter, including non-print mode, non-print mode,
Either a collection print mode or a direct print mode can be selected. Here, the non-print mode is a mode in which key-input characters, symbols, etc. are displayed on the liquid crystal display 40 without being printed.
What is the collection print mode? After correcting the characters and symbols entered by the key while they are displayed on the LCD display 40,
The direct print mode is a mode in which characters and symbols entered by key are displayed on the liquid crystal display 40 and printed simultaneously with the input. Further, the second mode selection switch 46
is a switch for selecting either a typewriter mode in which the terminal operates as a normal typewriter or a terminal mode in which the terminal operates as a data terminal by connecting to an external device.

The above components are arranged on the top surface of the keyboard 10, but on the right side of the keyboard 10, a brightness setting dial 48 for setting the brightness of the liquid crystal display 40 and a power switch 50 are further arranged.

A printing section 58 is provided at the rear portion of the keyboard 10 as described above. The printing section 58 is normally covered with a cover 60, but when in use, the cover 60 is opened as shown in the figure. A platen 62 is provided below the cover 60.
A carriage 64 is disposed so as to be movable along the longitudinal direction. A carriage 64 supports a thermal head 66, is guided by a guide rod 68, is moved along the length of the platen 62 by a drive device (not shown), and is moved around the guide rod 68 by another drive device (not shown). The thermal head 66 is rotated to press the thermal head 66 against the thermal paper 70 supported by the platen 62. Note that 72 is a release lever for moving a pair of paper feed rollers (not shown) disposed below the platen 62 for sandwiching and feeding the thermal paper 70 to a non-operating position where they are separated from each other. It is provided.

The typewriter having the above structure is controlled by a control circuit as shown in FIG.

In the figure, 80 is a central processing unit (hereinafter abbreviated as CPU) that constitutes the flag control means of the present invention.
In addition to the keyboard 10, this includes a read-only memory 82 (hereinafter abbreviated as ROM),
Random access memory 84 (hereinafter abbreviated as RAM), printing mechanism driver interface 86,
A display controller 88, an external interface driver receiver 90, etc. are connected. The printing mechanism driver interface 86 includes a printing mechanism 9 constituting the printing means of the present invention.
2 is connected to the display controller 88, and the liquid crystal display 40 is connected to the display controller 88. Further, an external interface 94 is connected to the external interface driver receiver 90 so that data can be exchanged between the present typewriter and an external device such as a typewriter of the same type or a personal computer.

The printing mechanism 92 includes the platen 62 and the carriage 64, a drive device for driving them, and a thermal head 66. The display controller 88 also has a display buffer memory 10 having the same number of digits as the liquid crystal display 40.
0 is built in, and the CPU 80 has a keyboard 10
The print data inputted from the display buffer memory 100 is sequentially filled with characters and symbols such as alphanumeric characters, numbers, spaces, arithmetic symbols, and other symbols, as well as code data corresponding to each print function such as line feed function and paper feed function. At the same time, pattern data corresponding to the code data is read from the ROM 82 and supplied to the display controller 88.

On the other hand, the print buffer memory 102 is RAM84.
The CPU 80 stores key-input code data in the print buffer memory 102, reads pattern data corresponding to this code data from the ROM 82, and supplies it to the print mechanism driver interface 86. The printing mechanism driver interface 86 drives the thermal head 66 of the printing mechanism 92 based on this pattern data, and also drives the coater and the like for operating the carriage 64. RAM84
is also provided with a text memory 104 that can store a certain amount of character/symbol data and print control data, and an underline flag register 10 that stores an underline flag.
6, and a collection buffer memory 10 constituting a 15-digit memory means of the present invention used in collection print mode and non-print mode.
8 is also provided. Further, the ROM 82 stores a program for controlling the operation of the entire typewriter.

The typewriter configured as described above can operate in a direct print mode for normal printing operations as described above, as well as a non-print mode and a collection print mode.
In addition to these typewriters, they can also be connected to an external device and operate in terminal mode, but since the operation itself is not directly relevant to the understanding of the present invention, the explanation will be omitted and the underlined text will be omitted. Only the parts related to attachment will be explained.

Assume that data as shown in FIG. 3 is input by operating the keys on the keyboard 10 while the typewriter is in the collection print mode. Here, 112 is an underline start symbol, and 114 is an underline end symbol, which are the underline start data and the underline start data issued from the keyboard 10 when the underline set key 30 and the underline reset key 32 are pressed, respectively. This represents underlined data. When such key inputs are performed, they are stored in the display buffer memory 100 and displayed on the liquid crystal display 40, and each time a new character or symbol is input, the display is shifted one digit to the left. Key-input data is displayed in the buffer memory 10 in this way.
0, it is also stored in the collection buffer memory 108, and the code data corresponding to the characters/symbols that overflow from the most significant digit of the collection buffer memory 108 is stored in the CPU.
Print buffer memory 1 of RAM84 by 80
02. The printing mechanism driver interface 86 controls the CPU 80 based on the code data stored in the printing buffer memory 102.
The printing mechanism 92 is driven by the pattern data read from the ROM 82 to perform printing.

At this time, the flowchart shown in FIG. 4 is executed. When the code data in the print buffer memory 102 is converted into pattern data and sent to the print mechanism driver interface 86, the program shown in the flow chart shown in FIG. 4 is executed.

That is, in step S1, it is determined whether the code data that overflowed from the collection buffer memory 108 is underline set data, but in the case of FIG. Since the data corresponds to , the determination result is NO, and the program execution moves to step S2.

In this step S2, it is determined whether the overflowed code data is underline reset data or not, but since the result of this determination is also NO, the program execution moves to step S3. A is printed in . Thereafter, the program execution returns to the main routine (not shown), and after the main routine is executed, steps S1, S2, and S3 are executed again, and B is printed. Similarly, after C is printed, the underline set data corresponding to the underline start symbol 112 will overflow from the collection buffer memory 108, so the result of the determination in step S1 will be
YES, and step S4 is executed. That is, the underline flag is turned ON so that the next overflowing data will be underlined.

Therefore, in step S3, which is executed after steps S1 and S2 are executed when the code data of D overflows from the collection buffer memory 108, D is printed and automatically written below. will be underlined. Similarly, an underline is added when printing E and F, but after that, the code data that overflows from the collection buffer memory 108 is marked with an underline end symbol 114.
Since the underline reset data corresponds to step S2, which is executed following step S1,
The determination result becomes YES, and the program moves to step S5 for execution. In step S5, the underline flag is turned OFF in order to prevent data that will overflow from now on to be underlined. Therefore, H, I, and J that overflow thereafter are printed without underlining.

Similarly, from now on, K, L, and M will be printed with an underline, and N, O, and P will be printed without an underline.

If there is no error in the key-input data, display and printing are performed as described above, but while the key-input data is displayed on the liquid crystal display 40 (more precisely, the 108), if the typist notices that there is an error in the underlining position, for example, in the input data of FIG. 3, all characters from D to M need to be underlined. If you notice that
Operate the left cursor key 22 to move the cursor on the liquid crystal display 40 to the underline end symbol 114.
By operating the delete key 26 after moving to the bottom of the underline reset data, the underline reset data corresponding to the underline end symbol 114 can be deleted, as shown in FIG. 3. As a result, underlines will be added to the characters D through M. That is, the underline set data corresponding to the underline start symbol 112 located between J and K is stored in the collection buffer memory 1.
Even if there is an overflow from 08, the underline flag is only kept ON at step S4 in the flowchart of FIG.
Since no effect is produced, there is no need to intentionally delete the data corresponding to this underline start symbol 112.

In addition, in the data shown in Figure 3, the characters that should be underlined are D, E, and F.
If you understand that K, L, and M do not need to be underlined, then
The data corresponding to the underline start symbol 112 between J and N may be deleted as shown in FIG. This alone prevents underlines from being added below K, L, and M, and there is no need to intentionally delete the underline termination symbol 114 between M and N.

As is clear from the above explanation, when the typewriter of this embodiment is in the collection print mode, if it becomes necessary to add an underline during key input of data to be printed,
When the underline set key 30 is operated, the underline set data is displayed in the buffer memory 100.
and collection buffer memory 108 together with normal print data, and when character/symbol data following the underline set data is printed, an underline is automatically added to the data. When the underline reset key 32 is operated, the underline reset data is stored in the display buffer memory 100 and the collection buffer memory 108, and the character/symbol data following that data is printed. In this case, underlining will not be added. That is, when printing character/symbol data sandwiched between underline set data and underline reset data, an underline is automatically added. In addition, if it is discovered that there is an error in the underline position, the delete key 26, insert key 28, underline set key 30, and underline set key 32 can be operated in the same way as for normal print data. Therefore, the underlining position can be easily changed by deleting or inserting the underline set data or underline reset data.

The above description has been made for the case where the typewriter of this embodiment is used in the collection print mode, but even when the typewriter is used in the direct print mode, the underline set key 30 is operated during key input of print data. For example, the characters/symbols corresponding to the print data entered by key after that will be printed with an underline, and if the underline reset key 32 is operated, no underline will be added from then on. .

Also, when the typewriter of this embodiment is used in the non-print mode, the underline set key 30 and the underline reset key 3 are similarly pressed.
2, commands are issued to start underlining and end underlining, but after a considerable amount of key-input data is stored in text memory 104, or Even after the creation of one text is completed, the underline start and end positions can be changed arbitrarily. That is, if it becomes necessary to correct the underlining position while registering data in the text memory 104, by operating the left cursor key 22, the portion displayed on the liquid crystal display 40 will change to the left portion of one print line. If the right cursor key 24 is operated, the screen moves to the right part.
Furthermore, if the left cursor key 22 and the code key 20 are operated simultaneously, the lines above the line currently displayed on the liquid crystal display 40 will be sequentially displayed. If you operate both at the same time, the data in the row below will be displayed. Therefore, it is possible to search for the part where the underlining position should be changed, and with the desired part displayed on the liquid crystal display 40, move the cursor under the underline start symbol or the underline end symbol. The data corresponding to these symbols can be deleted or corrected as desired, and the corresponding data can be inserted at desired positions. Also,
If it becomes necessary to correct the underlining position after the registration of print data in the text memory 104 is completed, by operating the left cursor key 22 and the code key 20 at the same time, the text memory 10
The last part of the bottom line of the text stored in step 4 will be displayed on the LCD display 40, and if you perform the same operation again, the beginning of the bottom line will be displayed, and if you repeat the same operation again, the beginning of the line above will be displayed. Since it is displayed on the liquid crystal display 40, the underline position can be found and corrected in the same way as in the case described above. In this case, the text memory 104 constitutes the memory means of the present invention.

Although one embodiment of the present invention has been described in detail above, the present invention is not limited thereto. For example, an underline start command that commands the start of an underline, and an underline end command that commands the end of the underline. Any means for inputting these commands may be used as long as it can input both commands in any order.
For example, it is possible to issue an underline start command when only the underline key is operated, and an underline end command when the underline key and code key are operated at the same time. .

The present invention can also be applied to typewriters that are not equipped with a direct print mode, collection print mode, or non-print mode, or are equipped with a text memory but are not equipped with a typewriter such as a liquid crystal display. Even in a typewriter that is not equipped with a display means, the underlining position can be corrected while viewing the printed text, and it is not necessarily essential to have a display means.

Although not illustrated individually, it goes without saying that the present invention can be implemented with various modifications and improvements based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
