Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document processing apparatus having a printing means capable of performing alignment processing on input characters and printing them.

[Prior Art] Conventionally, this type of apparatus has been provided with a function of executing alignment processing to reduce the burden of human processing such as tabulation processing and numerical data processing, and to align and print input information.

Normally, a human position control character such as a decimal tab is used as the alignment position, and the input numerical data is arranged and displayed or arranged and printed based on this alignment input position.

[Problems to be Solved by the Invention] However, since conventional alignment target characters employ only decimal point data, their use is limited to inputting numbers. Therefore, in the boat fishing table processing, only numbers can be used as elements in the table.

Furthermore, data types delimited by decimal points cannot perform alignment processing on non-numeric data, such as numeric data representing time data delimited by colons "=". In addition, when tabulating the ``='' symbol that indicates the result of a calculation formula, the above alignment process cannot be executed and the user is forced to input the digit alignment manually, and the alignment process cannot be enabled. I couldn't get it to work.

In addition, for document processing devices that can function multiple characters, such as period ",", comma ",", semicolon ";", etc., as alignment target characters, the above-mentioned restrictions on the use of alignment target characters are relaxed. However, as a line format, the alignment position and alignment target character are one
Since it is configured to correspond to one pair, only one alignment target character can be used at the same position (same digit).
For example, if you are creating a table in which numbers including decimal points and times are mixed, and periods and colons are in the same digit, you must select one of them as the alignment target character in advance. Not,
For the other character to be aligned, the user is forced to manually input the alignment, or to change the settings of the character to be aligned each time, which is a complicated setting process, which significantly degrades the original document information input process. There was a problem.

Furthermore, in devices that have an alignment function as part of the line format function in addition to simple decimal tab alignment function processing, similar processing is performed independently, so the creation of alignment processing programs takes up a large amount of the limited memory capacity. There were also problems with software development that became obstacles.

This invention was made to solve the above problems, and by simultaneously registering and managing multiple arbitrary characters input as alignment targets for the same digit position as alignment target characters, the specified digit It is an object of the present invention to obtain a document processing device that can realize alignment processing that includes a plurality of target characters in a position.

[Means to solve the problem]

A document processing device according to the present invention includes: a designation means for designating a plurality of arbitrary alignment target characters for the same digit; a target character storage means for storing a plurality of arbitrary alignment target characters specified by the designation means; and a first control means for controlling each alignment process to the same digit by the printing means based on each alignment target character stored in the target character storage means and alignment position information stored in the alignment position storage means. It is something.

Further, an alignment target character data memory is provided in which a plurality of alignment target characters that can be specified for the same digit are stored in advance.

Furthermore, a second control means is provided for controlling each alignment process to the same digit on the display means based on each alignment target character stored in the target character storage means and alignment position information stored in the alignment position storage means. It is something that

Further, target character candidate display means is provided for displaying alignment target character candidates registered in the target character storage means on the display means.

[Operation] In the present invention, when arbitrary alignment target characters for the same digit are sequentially specified, the plurality of arbitrary alignment target characters specified are stored in the target character storage means. Here, when printing by the printing means is started, the first control means controls the printing means to perform the same alignment based on each alignment target character stored in the target character storage means and the alignment position information stored in the alignment position storage means. It controls the alignment position of each digit and enables alignment processing using different alignment target characters on the same digit.

Further, by selecting and reading out the alignment target characters stored in the alignment target character data memory, it is possible to perform alignment processing using arbitrary alignment target characters that are different on the same digit.

Furthermore, when the printing data for the printing means is stored, the second control means controls the same printing data for the display means based on each alignment target character stored in the target character storage means and the alignment position information stored in the alignment position storage means. It is possible to control each alignment process to a digit and display the alignment process.

Further, the target character candidate display means reads out the alignment target character candidates registered in the target character storage means and displays them on the display means, thereby making it possible to display a target character candidate that is arbitrarily specified and input.

The alignment processing operation in the document processing apparatus according to the present invention will be described below with reference to the flowcharts shown in FIGS. 8 to 11 stored in the ROM 4 shown in FIG. 1.

[Main Routine] FIG. 8 is a flowchart showing an example of the main routine in the document processing apparatus according to the present invention. In addition, (1
) to (10) indicate each step.

When the power supply 1 is turned on, main routine processing is started and an initial operation is performed (1). This behavior includes
Initialization of the RAM 5 includes processing such as clearing the work RAM 5A and print buffer 5B, initialization of the printing device 9 to a printing standby state, and initialization of the display 10.

When the initialization is completed, the key input from the input device 2 is started, and it is determined whether or not there is a key input 2).
If NO, it waits for the key input, and if YES, the input key data is converted into a code number that can be recognized within the CPU 3 (3). Next, it is determined whether the converted code number is a command for setting an alignment position (4), and if YES, an alignment position registration processing routine to be described later is executed (5), and the process returns to step (2).

On the other hand, if the determination in step (4) is No, it is determined whether the converted code number is an alignment target character setting command 6), and if YES, the alignment target character registration processing routine is executed 7), step (2) ).

On the other hand, if the judgment in step (6) is NO, it is judged whether the converted code number is an alignment execution command 8), if YES, the alignment processing routine is executed 9), and if No, other keys are selected. To execute the process 10), return to step (2). Below, power supply 1
The processes from step (2) onwards are repeated until the switch is turned off.

[Alignment Position Registration Process] FIG. 9 is a flowchart showing detailed steps of an alignment position registration process routine in the document processing apparatus according to the present invention. Note that (11 to (22)) indicate each step.

First, the absolute value of the carriage of the printing device 9 is determined by the workpiece W'O
The value of the tab count TC stored at the head of the dub buffer 5C is read into the work W4, and the address of the tab position I is read into the work W1 (1). Next, it is determined whether or not there is no tab position or alignment position registered (workpiece W4=O) 2), Y
If it is ES, proceed to step (11) onwards and execute the registration process to the tab buffer 5C, but if it is determined that it has already been registered (if No), which position in the tab buffer 5C corresponds to the current position? In order to perform the process of searching whether the
3). Next, since the bit D15 of the tab position is an alignment position flag indicating whether it is a tab position or an alignment position, the bit D15 of the workpiece W2 is masked 4) so that the workpiece WO indicates a purely absolute position.

Next, the work W is used as a pointer in the tab buffer 5C.
Increment the value of l by 2 and update work W1 to point to the address where the next position is stored. Compare the current positions (6), and if the current position is smaller, register the current position as the alignment setting position in the tab buffer 5C where the position of the workpiece W2 is stored.
To align the pointers, the value of work W1 is decremented by "2" (7).

On the other hand, if the value of the workpiece W2 is equal to the current position as determined in step (6), the process proceeds to step (10), and the tab buffer 5C determines whether the position registered in the tab buffer 5C is the tab position or the alignment setting position. If it has already been set (if YES), the process ends without doing anything, and if No (if it is set as a tab position), the same position is set as the alignment position. Return to step (7) to register. On the other hand, if it is determined that the current position is larger in step (6), the process proceeds to step (8) for comparison with the next position in the tab buffer 5C, and a loop for searching within the tab buffer 5C is performed. Decrement the work W4 as a counter and judge whether all the tab positions have been searched for the number of tab counts (W4=0)9); if NO, step (
Returning to step 3), if YES, proceed to step (111). By the way, a pointer for registering the alignment position has been given to the workpiece W1 through the series of processes from steps (2) to (10).

Next, it is determined whether there is space in the tab buffer 5C, that is, whether the tab buffer 5C is in the FULL state, and if YES, the buzzer 8 is operated (12), and the operator is notified that registration is impossible. , ends the process.

On the other hand, if the judgment in step (11) is NO, the tab count is incremented 13), the bit D15 of the workpiece WO indicating the current position is set 14), and the workpiece W4
is "0" (15), if YES, proceed to step (22) or later; if No, workpiece W1
Give the data pointed to by work W5 (16), set the contents of work O as the address pointed to by work W1 (17), give the contents of work W5 to work WO (18), and add "2" to the contents of work W1. 19), change the contents of work W4 to “1
”20), the contents of work W4 are rO
Judge whether it is J or not (21), if No, step (1)
Returning to step 6), if YES, the address pointed to by work W1 is updated to the contents of work 0 (22), and the process ends. Through a series of steps (15) to (22), a new alignment position is registered at the address indicated by the workpiece W1 as a pointer, and subsequent data is sequentially stored at an address 2 bytes ahead. The data in the tab buffer 5C is sorted in descending order.

[Alignment Target Character Registration Process] FIG. 10 is a flowchart illustrating an example of the alignment target character registration process procedure in the document processing apparatus according to the present invention. In addition, .

(11 to (9) indicate each step.

Decimal points are set as alignment target characters by default, but here, any character other than alphanumeric newly set by the operator is registered as an alignment target.

First, wait until the input device 2 receives the key power.1)
Once the key is input, the input key is converted into an internally recognizable code number (2). Next, determine whether the input key is a character code.31, YES
If so, further judge whether it is an alphanumeric 4), if YES (if No in step (3))
Since it is not recognized as a character targeted for alignment,
After operating the buzzer 8 to notify the operator of the registration error (5), the process returns to step (1) and the alignment target character registration process is executed again.

On the other hand, if it is determined in step (4) that the character can be registered as an alignment target character, the code number stored in the alignment target character storage memory 7 is compared with the code number of the character to be registered this time. 6), it is determined whether the code number is equal to an already registered code number 7), and if NO (it is determined that the manually entered code number is unregistered), the free space in the alignment target character storage memory 7 is The input character code is stored (8) and the process returns to the main routine.

On the other hand, if the determination in step (7) is YES (if it is determined that the input code number has already been registered), the operator is notified by operating the buzzer 8 (9), and the process ends.

For example, when creating a timetable as shown in Figure 7,
We want to align the time part with a colon ":", so by inputting the key corresponding to the colon "=" from the input device 2 while waiting for key input in the above subroutine, we can select the decimal point as the character to be aligned. A colon ":" is registered outside.

[Alignment Processing] FIG. 11 is a flowchart showing detailed steps of an alignment processing routine in the document processing apparatus according to the present invention. Note that (11 to (31)) indicate each step.

This flow is called when an alignment execution command is given by key input from the input device 2. In addition, the work WO in the work RAM 5A is the current position, the work W1 is the alignment position, the work W2 is the print start position, W3 is the print end position, the work W4 is the character width, the work W5 is the left margin position, and the work W6 is the right position. Margin position, bit B7 of flag F1 is used as a flag to indicate that alignment target character has been input, and works WO, W5 . W6 is set by the main routine processing. First, a search is made to see if the position to be aligned, that is, the closest alignment position in the printing direction from the current position indicated by the carriage on the printing device 9, is registered in the dub buffer 5C (1).

Next, it is determined whether the corresponding alignment position exists (2), and if NO, the buzzer 8 is operated to notify the operator that the alignment process cannot be executed (3), and the process is terminated.

On the other hand, if the judgment in step (2) is YES (the alignment position exists), the searched alignment positions are stored in each of the workpieces Wl, W2, and W3, and the printing start and end positions are stored in (4). Initialize.

Next, bit B7 of the input flag F1 of the character to be aligned is cleared (5).

Next, it enters a state of waiting for a key input (6), and when a key input from the input device 2 is received, the code number is converted into an internally recognizable code number (7). Next, the character width of the character corresponding to the internal code number is set in advance and read into the work w4 from the data group of the ROM4 (8), and it is determined whether the input key is an alphanumeric character 91.
If YES, check bit B7 of flag F1 to determine whether the alignment target character has been input, that is, whether bit B7 of flag F1 is "1".
0), if YES (if already input), proceed to step (24) to process the print data after the alignment position and update the print end position; if No, proceed to process the print data before the alignment position and update the print end position. Execute the process of updating the print start position (storing the content obtained by subtracting the content of workpiece W4 from the content of workpiece W1 to workpiece W2) (
11). Next, as a result of updating the print start position, check whether the position returns to the front of the current position (W2>WO
) 12) If NO (W2≦WO), store the input characters as print data in the print buffer 5B 13), return to step (6), and if YES (the print start position is lower than the current position) If the value is small),
After invalidating the input character and returning the printing start position to its original state (W2←W2-W4) (14), the operator is notified of the error by buzzer 8 (29).
), the process returns to step (6) and waits for the key to be input again.

On the other hand, if it is determined in step (lO) that the character to be aligned has already been input, the print end position is updated (W3←W3+W4). Next, it is determined whether the update process has exceeded the write margin position (W3>W6) L.

(25), if YES, return the print end position to the original state (W3-W3-W4'), invalidate the input character (26), proceed to step (29), and after error processing, proceed to step (6). Go back and wait for the key to be re-entered.

On the other hand, if the determination in step (25) is No, the process proceeds to step (28), where the input data is stored as print data in the print buffer, and the process returns to step (6) to wait for the next key manual process.

On the other hand, if it is determined in step (9) that the input key is not an alphanumeric key, the process proceeds to step (15) to determine whether it is a decimal point, and if YES, the process proceeds to step (23). , flag F
It is determined whether bit B7 has already been set by looking at l, and if bit B7 has been set, the character is regarded as not an alignment target character but a normal character and the process proceeds to step (24).

On the other hand, if the judgment in step (23) is No (in the case of a character to be aligned that is input for the first time),
After setting bit B7 of flag F1 (27), the input data is stored in the print buffer 5B so that the character to be aligned is printed at the alignment position (28), and the process returns to step (6).

On the other hand, if the determination in step (15) is No, it is determined whether the input data is a character to be aligned (16), and if YES, step (23) is performed.
If the answer is No, determine whether it is a line feed command (return code) 17), N.

In this case (when the input data is not a line feed command), it is necessary to judge whether it is an alignment execution command or not.
8) If YES, print the currently stored data in the print buffer 5B by the printing device 9 for the next alignment process execution21), and use the value of the workpiece wo indicating the current position to indicate the printing end position. After updating (WO-W3) with the value of the workpiece W3 (22) and clearing the printing buffer 5B, the process returns to step (1) to perform the next alignment process.

On the other hand, if it is determined in step (18) that the input data is not an alignment execution command, it is determined whether the input data is a character code (19), and if YES, the process returns to step (10) and the alpha After executing the same process as when a numeric key is input and notifying the operator that an abnormal key has been input by operating the buzzer 8 (20), step (6)
) to wait for the next key manpower.

On the other hand, as determined in step (17), the data stored in the print buffer 5B is transferred to the workpiece W2 indicating the print start position.
The printing device 9 prints according to the workpiece W3 indicating the print end position, and after feeding the paper, the carriage is returned to the left margin position 30), and the workpiece WO indicating the current position of the carriage is printed according to the value of the workpiece W5 indicating the left margin position. Execute the update (WO←W5) process 31),
Finish the process.

By the procedure explained above, the 9th timetable of the timetable shown in FIG.
When attempting to print from line to line 11, move the carriage of the printing device 9 to the position of [mu]J to set the alignment position, and move the colon "=" as the character to be aligned to the memory for storing the character to be aligned. 7, input an alignment execution command from the input device 2, and then input one after another using the input key procedure shown below.

A concrete example of key processing is as follows.
