[Industrial applications]

The present invention relates to a document processing apparatus, and more particularly, to a document processing apparatus for displaying, for example, an operation method of a keyboard to an operator.

When operating the keyboard, which key should be pressed with which finger (the most functional) is determined for each key.
Once decided.

When trying to create and edit a document smoothly using a document processing device such as a Japanese word processor that has the function of creating Japanese documents, remember the correspondence between the keys and fingers and operate the keyboard accurately and quickly. It is indispensable to do.

[Conventional technology]

Since the correspondence between the key and the finger to press the key is not clear even when looking at the keyboard itself, an operation manual for beginners is prepared. Then, the operator looks at the keyboard diagram shown in the operation manual,
You will learn the correspondence between the keys and the fingers.

When actually trying to remember the correspondence between the keys and the fingers by operating the keyboard, the screen displayed on the display device of the document processing apparatus as shown in FIG. While looking at the same screen), the user operates the keyboard to learn.

By the way, the screen of the figure of the keyboard of the display device is as follows.
As shown in FIG. 10, for each finger, a plurality of keys to be pressed by the finger were simply surrounded by a thick line frame.

[Problems to be solved by the invention]

According to the above-mentioned prior art, even when trying to memorize the correspondence between keys and fingers by operating the keyboard, only the same figure as the operation manual is displayed on the screen. It was not very effective, and it was difficult to understand because the display was just surrounded by a thick line frame.

Therefore, from the viewpoint of the operator, even if the user operates the keyboard empirically, it is not very effective from the viewpoint of learning the correspondence between the keys and the fingers.

Further, when the keyboard is a thumb shift keyboard as shown in FIG. 10, only the display as shown in the figure is not effective especially when the operator is a complete beginner.

The present invention relates to the correspondence between a key on a keyboard and a finger to be pressed by the key, as well as a plurality of groups of keys to be pressed by the finger, and clearly displays each correspondence to an operator. It is an object of the present invention to provide a document processing device capable of performing the following.

[Means for solving the problem]

FIG. 1 is an explanatory view of the principle of the present invention, showing a document processing apparatus according to the present invention.

In FIG. 1, 1 is a processing device including a central processing unit (CPU) and a memory, 2 is a keyboard as an input device, 3 is a display device including a screen 31 for display, 4 is an input control unit, and 5 is a screen. A display processing unit for performing processing for displaying a desired display on 31; 6
Denotes a position recognition processing unit, 7 denotes an inversion processing unit, 8 denotes a table referred to for position recognition and the like, and 9 denotes a display control unit.

The operator presses an arbitrary key on the keyboard 2 to experience the correspondence between the key and the finger. This gives
The keyboard 2 sends matrix data corresponding to the pressed key (s) to the input control unit 4.

The input control unit 4 converts the matrix data into a code (JIS code) corresponding to the character indicated by the matrix data and sends it to the display processing unit 5.

The position recognition processing unit 6 refers to the table 8 and determines, from the code, which key the operator has pressed,
And the position of the key on the keyboard 2 is recognized. Further, the position recognition processing unit 6 recognizes, from the data indicating the position of the key on the keyboard 2, the number of fingers to press the key and the group of a plurality of keys to be pressed by the finger. .

To this end, the table 8 stores at least the code, data indicating the position of the key corresponding to the code on the keyboard 2, and data indicating how many fingers press the key (or group of keys). It is assumed to be provided.

The inversion processing unit 7 performs data processing necessary for inverting and displaying on the screen 31 a group of a plurality of keys to be pressed by the same finger including a key pressed by the operator and a finger to be pressed by these keys. I do.

The display control unit 9 receives the data from the display processing unit 5 and converts it into data constituting the screen 31. Further, the display control unit 9 displays a schematic diagram of the keyboard 2 including a schematic diagram of a finger to press a key of the keyboard 2 on the screen 31.

[Action]

FIG. 2 is an explanatory diagram of the operation of the present invention, and schematically shows a screen display enabled by the present invention.

In FIG. 2, 32 is a schematic diagram of the keyboard 2 (keyboard display), 33 is a schematic diagram of a finger to press a key of the keyboard 2 (finger display), 34 is an inverted display of the keyboard display 32, and 35 is A non-reversed display (normal display) on the keyboard display 32, a reversed display 36 on the finger display 33, and a non-reversed display (normal display) on the finger display 33 are shown.

Assume that the operator presses an arbitrary key on the keyboard 2, for example, "8", that is, inputs a character "8" (in this case, any finger may be pressed).

Based on the code corresponding to “8” generated in the input control unit 4, the position recognition processing unit 6 refers to the table 8 and determines the position of “8” on the keyboard 2 (and data indicating this). know. Further, based on this, the position recognition processing unit 6 first knows that, for example, “8” should be pressed with the middle finger, and then “ku”, “ki” and “ne” change “8” to “8”. Know that it is the key to be pressed with the same finger.

On the basis of this, the inversion processing unit 7 performs processing necessary to display the “8”, “ku”, “ki”, “ne”, and “middle finger” portions on the screen 31 as inverted display 34 and 36. I do.

When the screen 31 (FIG. 2) created by the above processing is displayed, the operator himself (arbitrarily selects)
The user can immediately know how many fingers are pressed and which group of keys is to be pressed.

In this way, by inverting the correspondence between the key and the finger on the screen 31 for any key, the operator can easily understand the key, and it is not necessary to look at the operation manual. In addition, since desired information on an arbitrary key can be immediately known, interactive learning with the processing device 1 can be performed, and the correspondence between the key and the finger can be quickly learned.

Note that the inverted display 34 and 36 are displayed in white characters (displayed in reverse black and white) as in "8" and "ku" in FIG. For the sake of brevity, "ki", "ne" and "middle finger" are hatched to distinguish them from the normal displays 35 and 37 (the same applies to the following embodiments).

〔Example〕

FIG. 3 is a block diagram of one embodiment, showing a document processing apparatus according to the present invention.

In FIG. 3, 11 is an auxiliary storage device such as a floppy disk, 12 is a printer as an output device, 71 is a first inversion range determination unit, 72 is a second inversion range determination unit, and 73 is data processing for inversion display. Inverting section that actually performs
Or the fourth table. In this embodiment, the keyboard 2 is a thumb shift keyboard,
Reference numeral 31 denotes a liquid crystal display screen.

From the keyboard 2, matrix data corresponding to the characters (hiragana, katakana, uppercase letters, lowercase letters, special symbols) specified by the operator pressing the 1 or 2 key is input to the input control unit 4. In this case, the operator designates one character by pressing one character key, or one character key and one of the thumb shift key or the semi-dull sound key.

The input control unit 4 is based on the matrix data,
Generates a JIS code defined for each character. The position recognition processing unit 6 once uses the table 8 to
The JIS code is converted into a code 41 having the configuration shown in FIG. 4 and including information on the key position and the shift key.

The first to fourth tables are read-only storage devices (RO
M), for example, provided in the processing apparatus 1.

The first table 81 is a “Kana table”,
Using the lower 8 bits of the code as an index, the position (41) of the corresponding key on the keyboard 2 for the kana character (hiragana, katakana) is known.

The second and third tables 82 and 83 are for knowing the positions on the keyboard 2 for characters other than the kana characters. The second table 82 contains JIS codes for characters other than kana characters, and the third table 83 contains data (41) indicating the positions of keys on the keyboard 2 corresponding to the codes of the second table. Is stored.

The fourth table 84 stores data indicating a finger to press a key as shown in FIG. The fourth table 84 is
Using the lower 4 bits (position data from the left) of the code 41 shown in the figure as an index, the finger to be pressed is known. That is, the lower 4 bits are 1 to C
The finger to be pressed is determined depending on which of (12). When the key is the uppermost key of the keyboard 2, a value obtained by adding 1 to the value of the lower 4 bits is used as an index. These are "1", ".", "U",
The “.” Key belongs to the same group, but there is no key to the left of the “1” key. Further, the fourth table 84 indicates that, for example, when the lower 4 bits are “4” or “5”, they belong to the same group to be pressed with “left index finger”, and the keys and their positions of this group Are all shown.

The position recognition processing section 6 refers to the first to fourth tables 81 to 84 based on the JIS code and knows the key position (41) and the like as in the processing flow shown in FIG.

From the upper 8 bits of the JIS code, the processing mode (Kana character display processing or other) is known.

In the case of kana character display processing (the upper 8 bits are × 23 or × 24), the first 8 bits of the JIS code are
Referring to table 81, the position of the key on keyboard 2 (4
1), and further, referring to the fourth table, the finger to press the key, the group of keys to be pressed by the finger, and the position thereof are known.

In the case other than the kana character display processing, it is checked whether or not the JIS code exists in the second table 82 (whether or not the character can be directly input from the keyboard 2).

If present, based on the code, referring to the third and fourth tables 83 and 84, the position of the pressed key on the keyboard 2, the finger to press the key and the key to press with the finger Know the group and its location.

If not, it is considered that the operator has pressed a key that is not the target of the display processing, and the processing is omitted (necessary processing is performed to instruct that fact).

Use the table when using the keyboard in English mode.
The same processing can be performed by replacing 81 to 83 with data for alphabetic characters. At this time, the table 84 does not need to be changed.

When the operator designates one character by simultaneously pressing the thumb shift key and the character key, the following is performed.

Since one JIS code has one-to-one correspondence with one character, the corresponding character can be known from the code. From the first and third tables 81 and 83, the character, that is, such code The key combination that caused the key to be generated can also be known. For this purpose, the first and third tables 81 and 83 have data of two keys including a thumb shift key as necessary as data (41) indicating the position of the key on the keyboard 2. .

Also, for the thumb shift key, the code shown in FIG.
Using the upper 2 bits on 41 as the index,
The table 84 is referred to. As a result, it is possible to know which one of the right and left thumbs is the thumb shift key to be pressed, and which group of keys is to be pressed by the thumb. For this purpose, the fourth table 84 has necessary data in addition to the data shown in FIG. 5 by using the upper two bits as an index.

The position recognition processing unit 6 sends the data obtained as described above to the first reversal range determination unit 71 for character keys (all keys to be pressed by fingers other than the thumb) and the accompanying key (presses with the thumb) Group of power keys, that is, a thumb shift key and a conversion key),
Each is sent. Since the thumb shift key may be pressed at the same time as the character key, in the inversion processing unit 7, the processing for the character key to be pressed by a finger other than the thumb is performed by the first and second inversion range determination units 71 and 72. The processing is performed independently in parallel with the processing for the accompanying keys including the thumb shift key pressed simultaneously.

The first inversion range determination unit 71 performs necessary processing on the data on the character key, and then sends the data to the inversion unit 73 that performs the actual inversion processing.

That is, for each key belonging to the group of keys to be pressed with the same finger including the key pressed by the operator, the range to be highlighted when each key is displayed on the screen 31 is determined. This range is determined based on the position of each character key on the keyboard 2 obtained from the position recognition processing unit 6 and within a predetermined distance from this position. on the other hand,
For a finger to press a group of these keys, a range to be highlighted when the finger is displayed on the screen 31 is determined. This range is, for example, data on a finger to be pressed, which is one of the data on character keys, and data indicating the position of the finger on the screen 31 when the corresponding finger is displayed on the screen 31 is the fourth data. It is obtained from the table 84, and is determined by setting a range within a predetermined distance from this position.

Similarly to the above, the second inversion range determination unit 72 displays the group of keys to be pressed with the same finger (one of the left or right thumb) and the finger when the group is displayed on the screen 31. Define the range to be done.

The inversion unit 73 includes a first and second inversion range determination unit 71 and
The actual inversion processing is performed in accordance with the inversion processing flow shown in FIG. 7 for the range indicated by 72.

Whether the key newly pressed by the operator belongs to the currently highlighted key group (whether it is the same group)
It is determined whether or not.

If the group is not the same, first, of the currently highlighted portion, the inverted display in the keyboard display (display indicating the position of the key) 32 is canceled by setting it to the inverted display again, and the normal display is performed.

Similarly, the inverted display in the finger display (display indicating the finger to be pressed) 33 is the normal display.

After the preprocessing and the end, for the key newly pressed by the operator, a group of keys to be pressed by the same finger as this key including this key is indicated to the operator as an inverted display on the keyboard display 32.

Similarly, the finger that presses the key group is set to the inverted display in the finger display 33.

If the key newly pressed by the operator belongs to the currently highlighted group, processing or omission is performed.

The above processing or each of the inversion ranges designated by the first and second inversion range determination units 71 and 72 is performed separately.

If the current display does not include the reverse display, the processing is omitted. If the key newly pressed by the operator is to be displayed without reverse display (for example, when the key is not on the keyboard 2 or is completely different processing such as a conversion key), the processing is performed. Is omitted.

FIG. 8 is a flow chart of the display processing of the present invention, and FIG. 9 is a view showing a screen obtained by the display processing of the present invention.

A program for learning the correspondence between the key and the finger is called by the instruction of the operator. As a result, an initial screen as shown in FIG. 9A is displayed.

If necessary, the operator presses a “Katakana key” or an “English character key”, etc., and rewrites the screen to display a correspondence between a key and a finger for katakana or an alphabetic character.

The operator presses a key on the keyboard 2. At this time, any key may be pressed with any finger.

In the process, if the operator presses a key indicating a menu other than the menu for learning the correspondence between the key and the finger, the menu ends.

In the processing, it is assumed that the operator presses "ku".

The input control unit 4 sends a JIS code corresponding to “ku” including the configuration as shown in FIG. 4 to the position recognition processing unit 6.

The position recognition processing unit 6 refers to the first and fourth tables 81 and 84 according to the processing flow of FIG. 6 based on the JIS code of “ku”. As a result, the position recognition processing unit 6 determines that “ku” should be pressed with the “right middle finger”,
Know that "8", "ki" and "ne" should be pressed with the same finger. Further, for each of the keys “8”, “ku”, “ki”, and “ne”, the position on the keyboard 2, in other words, the position of each key on the screen when the keyboard 2 is displayed on the screen 31 is shown. know. For example, the position of “8” is coordinate (5,40), “ku” is coordinate (6,41), and “ki” is coordinate (7,4).
2) “Ne” is the coordinates (8,43). In addition, when what is to be pressed with the “right middle finger” is displayed on the screen 31, the position on the screen for the display (for example, the coordinates (5, 64) are known).

The position recognition processing unit 6 performs the same processing as the processing for the thumb shift key, which is one of the accompanying keys, based on the upper two bits of the code 41 shown in FIG.

In the process of the position recognition processing unit 6, when the key or character does not exist on the keyboard 2 (or in the second table 82), for example, as shown in the processing flow of FIG. 6, the inversion process is omitted. You.

The data obtained in the processing and in
And sent to the second inversion range determination units 71 and 72.

The first inversion range determination unit 71 determines the inversion range as follows.

(I) A range of 15 dots horizontally and vertically from (5,40) for "8", (ii) A range of 15 dots horizontally and vertically from (6,41) for "ku", and (iii) Coordinates of "ki" (7,42) from the vertical and horizontal 15 dots each, (iv) "ne" from the coordinates (8,43) from the vertical and horizontal 15 dots, (v) "right middle finger" from the coordinates (5,64) from the vertical (5,64) Range of 72 dots and 16 dots horizontally.

Here, for the coordinates (X, Y), the ordinate X is in units of 18 dots, and the abscissa Y is in units of 8 dots. One dot is one dot of the liquid crystal matrix forming the screen 31.

In the second inversion range determination unit 72, the inversion range is determined in the same manner.

The actual inversion processing is performed in the inversion unit 73 based on the inversion range.

First, according to the processing flow shown in FIG. 7, the reverse display by the previous processing is canceled.

Next, processing is performed for the inversion ranges (i) to (iv) determined in the processing.

That is, the reversing unit 73 sets the reversing ranges (i) to (iv) in the work area (register) and reads out the display data of the area corresponding to the reversing ranges (i) to (iv) from the display control unit 9. This display data is data for actually displaying the screen 31 by the liquid crystal dot matrix. For example, a dot (character portion) for displaying black is set to logic 1 (ON), and a substantially white display which is another background is displayed. Is set to logic 0 (OFF).

Next, the inverting unit 73 performs a negative logical operation on each dot of the read data (inverts the logic).

The inverted data is written into the area corresponding to the inversion range (i) to (iv) of the display control unit 9 by the inversion unit 73.

The above processing is similarly performed for the inversion range (v) determined in the processing.

As a result of the processing, a screen is displayed as shown in FIG. 9 (B).

If necessary, the operator presses “Katakana key” or “English key” in the same manner as
Rewrite the screen to display the correspondence between keys and fingers for katakana or alphabetic characters. Thereafter, the processing is repeated.

For example, in the processing, the operator is "", "", "，", "re", "ゅ", "mo",
When any one of the characters "ya" and "i" is designated, the screen 31 becomes as shown in FIG. 9 (C).

The position recognition processing unit 6 uses the table 8 from the JIS code corresponding to the character one-to-one, and simultaneously presses the corresponding character key and, at the same time, presses the left shift key (to be pressed with the left thumb). Know that it can be obtained by doing so. It also knows that the character keys corresponding to these characters should be pressed with the "left index finger", and which key is pressed with the "left index finger".
Further, the user knows that there is a "non-conversion key" as a group of keys (associated keys) to be pressed by the "left thumb".

As a result of the above recognition, as shown in FIG. 9 (C), the "forefinger" and "thumb" are displayed in reverse on the left finger indicating the left hand, and the eight character keys and the two accompanying keys are displayed in reverse on the keyboard display. Is done.

FIG. 9 (D) shows still another example of the screen, in which the operator selects "go", "za", "ge",
The screen shows a case where any one of the characters “ze”, “bu”, and “be” is input.

As described above, the present invention has been described with reference to the embodiments. However, the present invention can be variously modified in accordance with the gist thereof.

For example, in FIG. 9 (B) No. "D", the key actually pressed by the operator and / or the character indicated by the operator and / or the character indicated by the same finger may be displayed. .

〔The invention's effect〕

As described above, according to the present invention, when an operation method of a keyboard is displayed to an operator in a document processing apparatus, for an arbitrary key pressed by the operator, a finger to press the key and a finger to press the key are displayed. The effect is that the group of keys to be pressed can be automatically displayed on the screen and can be clearly displayed by the inversion process, and interactive learning about the correspondence between keys and fingers can be performed.
