Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a processing device for editing text, and more particularly to a device of this type having a numbering function that can automatically introduce consecutive numbers.

For example, when creating an item list or the like in this type of processing device, a serial number (serial number) is usually placed at the beginning of each line to display the list of each item.

In such a case, conventionally, the operator inputs number information each time using the numeric keys at the position corresponding to each line position of the character input operation. Moreover, when entering this number information, it was necessary to make full use of spaces, indents, tab specifications, etc. to ensure that the digits were aligned in the same column position.

With the present invention, it is possible to input such consecutive numbers with the digits automatically aligned without having to input keys each time while considering the positional relationship, which simplifies the input operation. , it is possible to increase the speed.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 shows the external appearance of the device according to the present invention, and the device main body 1 includes a CRT display device (display means) 2 and characters on the input board. It has a key group 3 and a control key group 4.

In this case, the desired text is input using character key group 3, and this input text information is displayed on the CRT.
After being displayed on the display device 2 and subjected to desired editing processing, the text is sent to a text memory that stores and holds text information, and the text is created by a printer.

The display example on the CRT display device 2 in FIG. 1 shows the creation of a list, where 5 is a numerical serial number and 6 is text information such as articles.

FIG. 2 specifically shows the control key group 4 shown in FIG. 1. Numeral 21 is a numbering setting key for setting the serial number introduction matrix position in a row, and 22 is a numbering setting key for counting up the serial number to add text. A numbering key 27 is used to introduce the initial value during input, and 27 is an execution key for setting the initial value on the numbering counter when the initial value is input using the numeric keys.
Reference numerals 23 to 26 are movement instruction keys for moving the cursor mark M (see FIG. 1) on the CRT screen in the direction of the arrow on the key.

Next, the key operations shown in FIG. 2 will be briefly explained.

First, move the cursor to the first line of the text (which may be the beginning of the text) where you want to input the serial number. Then, the user operates the cursor movement instruction keys 23 and 24 to move the cursor mark M to the position in the line where the serial number is to be input. When the cursor reaches the most significant digit at the position to be input, the numbering setting key 21 is operated to set the matrix position, and then the initial value is input using the numerical keys.

For the initial value, if you want to suppress zero, enter the space key for the number of digits, then enter the initial value. For example, if there are 3 digits as a sequential number and the initial value is "1", "space", "space",
Just input “1”. Also, if you do not want to suppress zero, you can enter "001". Subsequently, when the execution key 27 is operated, the above-mentioned initial value is set in a counter (calculation register) which is a holding means.

In this way, in the first numbering operation, the operation up to setting the initial value is the numbering initial setting operation.

Thereafter, in a normal text input operation, character information is input in sequence, and when the serial number input position is reached, the numbering key 22 is operated, and a serial number counted up by a predetermined value is input.

In summary, the apparatus according to the present invention includes a cursor means for selecting and instructing a serial number input start position on a display screen of a display means, and a digit position for storing digit information at a predetermined column direction position indicated by the cursor means. a storage means, an initial value storage means into which an initial value of a serial number is introduced, a numbering instruction means for instructing input of a serial number at the input start position, and in response to an instruction from the numbering instruction means, the cursor is moved. Input the initial value number at the indicated position, and also input the sequence following the initial value number at the predetermined digit and position in the same column in subsequent rows based on the digit information stored in the digit position storage means. The control means for inputting the number will be described below with reference to FIG. 3.

30 is character key group 3 shown in FIG.
is a group of control keys. These key signals are fed to an input control circuit and encoding circuit 32, which outputs corresponding encoded signals.

Reference numeral 33 denotes an editing control circuit, which performs editing control such as character insertion and deletion. Reference numeral 34 is a text memory that stores character codes according to the order of operation of the character key group 30. The data in the text memory 34 is supplied to a CRT display control circuit 35 and displayed.

36 is a cursor counter, which includes cursor movement keys (23 to 26 in FIG. 2) and a character key group 30.
The count is controlled by This cursor counter 36 corresponds to the reading or writing position of the text memory 34, and is also displayed as a cursor mark on the CRT display device.

Reference numeral 37 denotes a pointer that stores position information in the column direction of the cursor counter 36 during the numbering initialization operation described above. 38 is a circuit that compares the cursor counter 36 and pointer 37 at the time of operation of the numbering key 22 during normal character input, and if they do not match, controls the space code generation circuit 46 to write a space in the text memory 34. Introduce the code.

39 is a digit counter that stores the number of digits of the numbering value, and initially the same number of digits as the maximum number of digits of the calculation register 42 is set, and each time the space key or numeric key is input during numbering setting, is counted down by 1.

That is, for example, if the arithmetic register (Rrg) 42 is composed of five digits, the initial value "5" is held in the digit counter 39, and the counter decrements by one each time a key is input. Therefore, when the setting is completed, the number of digits equivalent to the number of unnecessary upper digits of the calculation register 42 is stored.

40 is a space code detection circuit, which detects the space code when the space key is operated during the above numbering setting, and flags _F2.
Set (41).

42 is an arithmetic register, which in this example has a capacity of 5 digits. When setting the numbering of this calculation register 42, an initial value is set, and from then on, each time the numbering key 22 is operated, the calculation circuit 4
4, "1" is added. Further, the output of this arithmetic register 42 is subjected to zero suppression control by a zero suppression circuit 43. In this case, if zero is to be suppressed, the upper "0" is replaced with a space code and input into the text memory 34.

Note that 45 is a character code generation circuit, 47 is an OR gate, and 48 and 49 are flags F ₁ and F ₃ .

Next, the operation will be specifically explained according to the flowchart shown in FIG.

First, when performing a numbering operation, the numbering preset operation is first performed as described above. This is started by operating the numbering setting key 21, and this operation sets the flag.
Reset F ₂ (41) and further set flag F ₁ (48) (steps 100, 101, 102).

Next, the initial value is input using character key 3 (step 103). In this case, input including zero suppression and number of digits.

For example, to suppress three digit zeros, enter the space key, the space key, and the initial value "1" key. At this time, when the first space key is input, the character code of the space key is stored in the text memory 34.
is stored at the position indicated by the cursor. Furthermore, since flag _F148 is set, steps 104,
Progress from 105 to 109. Since this is the first input key, the process advances to step 110 and the position information of the cursor counter 36 in the column direction (horizontal direction) is transferred to the pointer 37. Next, digit counter 39
(Initially, the maximum number of digits in the calculation register 42 is "5" in the example.) is counted down by "1" (step 111). And cursor counter 3
Add 1 to 6 to indicate the next position, and since the space key is currently used, proceed to step 114 with the change in step 113, where the flag F ₂
Set (41).

Subsequently, when the space key is operated, the process advances from jump step 109 to step 111, and the above operations are repeated. Next, when the numeric key "1" key is operated, the steps start from the jersey step 113.
115, and the number “1” is in the calculation register 42.
will be introduced to

The initial value is set by the above operation, but in this example, the digit counter 112 is "2", "1" is introduced into the calculation register 42, and the flag F ₂ (41) is set. Ru. When the execution key 27 is operated in this state, the flag F ₁ (48) is reset (step 107).

Note that if zero suppression is not to be performed in the above operation, operate the 0 key, 0 key, and 1 key. At this time, flag _F241 in step 114 is not set.

Subsequently, the operator moves the cursor or inputs a desired text, and when the next numbering position is reached, the operator operates the numbering key 22.

Then, the comparison circuit 38 compares the previous pointer 37 and the current position of the cursor counter 36 to see if they match, and if they do not match, the space code generation circuit 46 outputs a space code to the OR gate 47.
is stored in the text memory 34 at the position indicated by the cursor. Furthermore, the cursor counter 36 is +1
(Steps 108, 116, 117, 118). This operation is repeated until the comparison circuit 38 matches.

This operation automatically inserts a space code up to the numbering position.

This is especially effective for operating the numbering function in the middle of a sentence (in the middle of a line), and press this numbering key 2 before the line numbering position.
If you operate 2, a space code will be automatically inserted.

Thereafter, when the comparison circuit 38 detects a match, the process proceeds from step 116 to step 119, where the arithmetic circuit 44 is driven and "1" is added to the arithmetic register 42.

Furthermore, the most significant digit (fifth digit) of the arithmetic register 42 is read out, and a comparison is made to see if the previous number of the digit counter 39 and the digit just read out are equal. Read from the calculation register 42 until they are equal (steps 120, 121,
122). Based on this coincidence detection, the process proceeds from step 121 to judge step 123.

In the case of zero suppression, as explained above, since the flag _F2 is in the set state, the process proceeds from step 12 to step 124, where it is determined whether the numerical value is "0" or not. If it is "0", the process proceeds to step 125.

Since _F3 has now been reset, a space code is generated by the space code generation circuit 46 and introduced into the text memory 34 (step 128).
Next, the cursor counter 36 is incremented by 1 and the next digit is read from the calculation register 42 (step 129,
130).

After that, proceed from steps 131 to 123 and 124.
If the numerical value is not "0", the flag _F3 49 is set, and the corresponding numerical code is introduced into the text memory 34 (steps 126, 127). From then on, F ₃
is set, so even if "0" is read, it will not be converted to a space code.

With the above operation, an updated numerical value is introduced every time the numbering key is operated.

Also, if you do not use zero suppression, set the flag
Since F ₂ has been reset, the jersey step
Proceeding from 123 to 127, all numerical values are converted into corresponding character codes, and the leading "0" is also introduced into the text memory 34.

In the above embodiment, a numbering key 22 for performing a numbering operation is provided, but this may also be used as another text-related key, such as a line feed key. Further, in the above example, the count is increased by "1", but it is also possible to increase the count by "2" or "3".

As described above, according to the present invention, it is possible to input sequential numbers with digits automatically aligned when creating an article list, etc., eliminating the need to input number keys each time, and simplifying the input operation of sequential numbers. It is extremely convenient, and the entire text information input process can be done efficiently and quickly.Furthermore, the numbering area can be set to any position by moving the cursor, so you can create the desired layout when creating a list. It becomes more efficient and easier to use.
