[0033]

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail below with reference to the drawings and tables. A general small electronic device to which the present invention is applied, such as an electronic calculator, has at least a display screen capable of displaying characters and an input keyboard in which numeric keys (0 to 9) are arranged. Table 1 is a table showing the basics of the character input means for inputting characters using the keys on the keyboard of the small electronic device in the present invention.

[0034]

[Table 1]

The first embodiment of the character input means according to the present invention is basically based on a pair of key pressing operations for pressing two predetermined keys in succession. In Table 1, the selection keys “a”, “b”, “c” ... “n” arranged side by side indicate the keys to be pressed the first time out of the pair of keys. The selection key is a key newly provided on the keyboard in the present invention. Vertically arranged number keys "1", "2",
"3" ... "0" indicates the key to be pressed the second time. The numeric keys are keys that have been conventionally provided on the keyboard. The code located at the intersection of the given selection key and the given numeric key (for example, "b4" at the intersection of the selection key "b" and the numeric key "4") is after this pair of key press operations. , Represents the characters displayed on the display screen of the device. Therefore, if the number of selection keys is N (N is an integer), the maximum number of different characters that can be displayed is N × 10. Usually, on a display screen capable of displaying characters, a cursor for visually confirming the current target position is displayed to the user, and a desired one is displayed at this cursor position according to the input.
Two characters are displayed.

The following Tables 2 to 4 show concrete examples based on the basic input means shown in Table 1.

[0037]

[Table 2]

Table 2 is an example of displaying English characters. Since there are 26 letters in all, if each key is made to correspond to one key, 26 keys must be added on the keyboard. However, according to the present invention, if the number N of the selection keys is 3 or more, all the English characters can be associated with the pair of keys. In the example of Table 2 (A), five selection keys “A”, “H”, “O”,
"V" and "X" are selected, and a total of 26 English characters are divided into 5 groups. That is, the A group includes B, C, D, E, F, and G with A as a head, and the H group includes I, I, J, K, L, M, and N with H as a head. The O group includes P, Q, R, S, T, and U with O as a head, the V group includes V with W as a head, and the X group includes X and Y and Z as a head. Is included. Each element included in each of these groups is associated with the number keys “1”, “2”, “3”, ...
A specific one character can be determined by the combination (α, β) of the first character of the group and the numeric key. For example,
(A, 1) is "A", (H, 4) is "K", (O, 7) is "U", (V, 1) is "V", and ( If it is X, 2), "Y" is uniquely determined. Table 2 (B) is another embodiment for English characters, but in this case, four selection keys “A”,
"H", "O", and "V" are selected, 26 characters are divided into four groups, and similarly, the characters in each group are sequentially associated with the numeric keys. As is clear from the specific example of Table 2, the present invention enables various character inputs by newly adding a small number of selection keys to the conventional keyboard. Since an object of the present invention is to enable character input with a minimum number of keys, it is preferable to basically add as few selection keys as possible.

In the case of the alphabetic characters shown in Table 2, the minimum number of selection keys is 3, as described above, but in practice, the number of selection keys is 5 or 4 as described above. Is due to consideration of user convenience. These five English letters are based on the very well-known nursery rhyme "ABC song" in Japan, and the first letters "A", "H", "O" of the break of this song,
“V” and “X” are extracted. It is extremely effective to use the selection key for these characters. If 26 characters are evenly divided into 5 groups, it may be difficult (especially for a user who is not familiar with English) to instantly determine which group a given character belongs to. On the other hand, if "A", "H", "O", "V", and "X" are divided into 5 groups with the leading character, which group the given character belongs to according to the above rhythm of the nursery rhyme. It can be easily determined, and the selection key to be pressed the first time can be selected immediately. However, it goes without saying that any number and combination of selection keys can be used in accordance with the principles of the present invention.

It is noted that the principles of the present invention are applicable not only to English letters, but to any given language in the world. Characters that are the mother of writing sounds in a given language, such as the 26 English letters, are called kanji. So is the Japanese syllabary Kana character. In any of the languages, the glyphs generally have a predetermined characteristic arrangement. For example, Japanese is arranged in the order of aiueo, English is A
It has a sequence in BC order. The present invention can be efficiently applied to any language by effectively selecting the above-mentioned selection key by utilizing such an array characteristic of the language.

Table 3 below shows an embodiment of the present invention in the case of inputting Japanese characters.

[0042]

[Table 3]

In the example of Table 3, the Japanese syllabary vowels "A", "I", "U", "E", and "O" are selected as five selection keys, and these and the numeric keys are used. All 50 sounds can be input in combination with. For example, (Oh,
If it is 2), it is "ka", if it is (i, 4), it is "chi",
If it is (u, 6), it is "fu", if it is (e, 9), it is "re", if it is (o, 0), it is "o", and (i, 0).
If so, "n" is displayed at the cursor position on the display screen.

Table 4 below shows another embodiment for inputting Japanese characters.

[0045]

[Table 4]

In the example of Table 4, the selection keys are the Japanese syllabary "a", "ka", "sa", "ta", "na", "ha",
Ten “Ma”, “ya”, “ra”, and “wa” are selected. In this case, the number of selection keys is slightly increased, but since the number keys are in the range of 1 to 5, it will be easy to press the number keys.

In the above, the character input means functions only when the number key is pressed subsequent to the selection key, and when the number key alone is pressed, normal number input is performed.

FIG. 2 is a diagram schematically showing a key arrangement on an actual keyboard based on the above-described examples of some selection keys. FIG. 2A is an example in which five English characters are arranged in a horizontal row using the selection keys. Figure 2 (B)
Is an example in which four alphabetic characters are used as selection keys and are arranged in a horizontal row. FIG. 2C is an example in which five kana characters are arranged in a horizontal row using the selection keys as selection keys. Figure 2
(D) is an example in which 10 kana characters are arranged in two horizontal rows using the selection keys as selection keys. When these arrangements shown in FIG. 2 are applied to a safe with an electronic input keyboard, etc.,
Since a password made up of characters can be used instead of a personal identification number, it is preferable because it is easy to memorize.

The following Table 5 is a diagram showing a second embodiment of the character input means according to the present invention.

[0050]

[Table 5]

Also in this case, the character to be displayed is determined by the combination of a pair of keys that are successively pressed. The selection key to be pressed first is the same as that in the first embodiment described above, but for the numeric key to be pressed next, only one predetermined numeric key is used as the circulation key. In Table 5, this predetermined one numeric key is referred to as the "1" key. Then, every time the "1" key is pressed after the selection key, the displayed character changes in sequence. For example, if you press the selection key "A" and then the key "1" once, "A" will be displayed, if you press it again, "B" will be displayed, and if you press it again, "C" will be displayed. Is displayed. As described above, the characters A, B, C, D, E, F included in the group A are selected according to the number of times the key "1" pressed after the selection key "A" is pressed.
And G are displayed cyclically. If any key other than the key "1" is pressed midway, the character displayed at that time is confirmed and the cursor moves to the next position. In this example, a predetermined one numeric key is used as a circular key, but any key having a circular function may be used, and therefore it need not be a numeric key. Also, a dedicated key may be used instead of being combined with another key. The second embodiment has been described by taking the case of English characters as an example, but of course, like the first embodiment, it can be applied to a given language.

FIG. 3 is a diagram showing a third embodiment of the present invention. This is not a character input means itself, but a means for cursor operation and edit operation which are closely related to the character input function. In FIG. 3, in addition to the conventional 26-letter alphanumeric keys, five keys “I” according to the present invention,
The keyboard 1 in which the cross-shaped keys 40 of "II", "III", "IV", and "V" are arranged is shown.
Conventional cursor keys usually consist of four keys, and by pressing each of them, the cursor is moved in the up, down, left and right directions. Each of the keys forming the cross-shaped key 40 in the present invention has no response when pressed only once, and only when the different keys or the same key is pressed twice or more, the cursor is moved according to the combination, Perform operations such as specifying the range with the cursor. For example, for moving the cursor, use the combination of two keys (III, I) to move up,
The cursor movement is executed downward by (III, V), rightward by (III, IV), and leftward by (III, II). With the conventional cursor keys, only the function of moving the cursor by pressing the key once can be given. On the other hand, in the present invention, the cross-shaped key is provided so that the predetermined function is executed only when the key is pressed twice or more. This is not intended only for cursor movement operation within the cross-shaped key, but various functions are available for each key combination within the cross-shaped key and the combination of the cross-shaped key and any key on the keyboard. Is intended to be added so that operations for a very large number of functions are realized as compared to the total number of keys on the keyboard.

Examples of editing operations and the like which are closely related to the character input function are execution, selection, deletion, copying, cancellation and movement. In addition, dakuon, long sound, which can also be called auxiliary character input function,
Features such as small letters are also needed. In order to realize these, many function keys are required as in a general word processor dedicated machine. The cross-shaped key of FIG. 3 according to the present invention realizes various document processing functions in a small-key keyboard of a small electronic device.

Although examples are shown in FIGS. 4 to 6 later, the number and arrangement of keys selected for assigning such function keys are not limited to those shown in FIG. Even if the number of function keys is one, the same setting (for example, a combination of pressing the key twice or more and a combination of other keys) is possible, and the arrangement shape is a cross shape or a T-shape, U-shape, I-shape, L
Any of a glyph shape and a combination thereof can be considered. Two
The combination of key pressing operations more than once corresponds to M (M is an integer) duplicate combinations of two or more times selected as function keys.

FIG. 1 is a diagram schematically showing an example of a keyboard embodying the embodiment of the present invention described above.

The keyboard of FIG. 1 has ten numeric keys and five selection keys (A,
(H, O, V, X) and a pound sign key (#) are arranged. The combination of the five selection keys and the number keys is
It constitutes the above-mentioned English character input means. Further, the five selection keys are arranged in a cross shape and also serve as the cross-shaped keys described in FIG. Therefore, (H, V), (H,
The cursor can be moved up, down, left, and right by pressing a key combination of (X), (H, A), and (H, O). Regarding the cursor movement operation, after pressing the key first, the next key may be intermittently moved to intermittently move, and the next key may be held down to be continuously moved. .

In the keyboard example of FIG. 1, when the optical fiber is wired in each home in the future and the television and the telephone can be connected to use the television as a display screen, the keyboard portion of the telephone can be used. It is supposed to have various functions equivalent to those of a normal word processor.

Next, FIG. 1 will be described in detail. For the sake of convenience, a description of each key pressing operation and the function executed by each key is described around each key. "V." above the key means a combination of first pressing the selection key "V" and then that key, and the function performed thereby is also described. Also, if two or more functions are written, it means that these functions circulate each time the key is pressed, and in this case, the function that was actualized when another key was pressed is confirmed. To do. Further, "w" means an operation of pressing twice in succession, and "t" means an operation of pressing three times in succession. Further, the bold arrow represents the cursor movement by the combination of these pair of keys as described above. The open and thin arrows indicate that each pair of key combinations performs the function described therein.

For example, on the right side of the selection key "X", "V ↓
The phrase "next page" means that the operation of moving to the next page is executed by pressing the selection key "V" and then the selection key "X". Also, "wV window I" above the number key "1" means that the window I is displayed on the display screen when the selection key "V" is pressed twice and the number key "1" is pressed. To do. Also, "V. ゜" above the number key "3" means that when the selection key "V" is pressed and this number key "3" is pressed, the voiced characters are displayed and the number is displayed again. This means that pressing the key “3” will change the voiced sound into a semi-voiced sound. Also, select key "V"
The "tVv mark tab" at the top of means that the mark tab of "v" is displayed when the selection key "V" is pressed three times. Furthermore, the "w range designation" on the upper part of the selection key "H" starts the range designation when the selection key "H" is pressed twice, and when the selection key "H" is pushed again after moving the cursor, the range is designated. Means that the specification is completed.

The following Table 6 is a table showing an example of a correspondence relationship between a combination of a pair of key pressing operations within the five selection keys on the keyboard of FIG. 1 and a function executed according to the combination.

[0061]

[Table 6]

In Table 6, the columns for each function are two in upper and lower rows.
Although described below, the upper function is the function when the horizontal axis selection key is first pressed, and the lower function is the function when the vertical axis selection key is first pressed. However, the "w" operation in which the same key is pressed twice in succession is shown without being divided into stages, and "x" is marked when there is no corresponding function.

Table 7 below shows a correspondence relationship between a combination of a pair of key pressing operations of the five selection keys and the numeral keys or the "#" key on the keyboard of FIG. 1 and the function executed in accordance with the combination. It is a table showing an example of.

[0064]

[Table 7]

Table 8 below shows "w (twice press)" operation of the five selection keys on the keyboard of FIG. 1 and one or two press operation of the numeric keys (that is, 0 to 99). 6 is a table showing an example of a correspondence relationship between combinations and functions executed in accordance therewith. “None” indicates a case where only the “w” operation of the selection key is performed. “X” indicates that the device cannot be used. For example, select key "V"
The reason why the combination with the numeric keys “10” to “99” is not allowed in is because it is complicated to distinguish between the one-time pressing and the two-time pressing of the number keys. Here, by disabling the combination of “None” and the numeric keys “0” to “9” such as the selection keys “A” and “O”, the numeric keys in a wider range than this can be achieved. "10"
Note that combinations with "99" are possible.

[0066]

[Table 8]

Table 9 below shows a combination of the "t (three times press)" operation of the five selection keys on the keyboard of FIG. 1 and the five selection keys or the numeric keys "10" to "99". 9 is a table showing an example of a correspondence relationship between a function and a function executed accordingly.
“None” indicates a case where only the “t” operation of the selection key is performed. Also in this example, by omitting the combination of “None” and the numeric keys “0” to “9” such as the selection keys “A” and “O”, the numeric key “1”, which is a wider range than this, can be obtained.
A combination with 0 ”to“ 99 ”is possible.

The following Table 10 is displayed by operating the "wV window I" (the selection key "V" is pressed twice and then this number key "1" is pressed) described above the number key "1". Windows I displayed, and Windows II displayed by the operation of "wV window II" (press the selection key "V" twice and press this number key "2") written above the number key "2". Here is an example:

[Table 10]

FIG. 4 is a diagram showing some other examples of a keyboard in which five selection keys are arranged as cross-shaped keys. In this way, it is possible to set an arbitrary array of horizontally long, vertically long, and square in accordance with the outer shape and design of the applied device. In FIG. 4C, in the case of kana character input, the five selection keys are “a”, “i”, “u”,
These are examples of "e" and "o".

FIG. 5A is a modification of the cross-shaped key of FIG. 3, which has four keys "I", "II", "III", and "I".
In this example, “V” is arranged as a cross-shaped key. In the case of four keys, basically, similar to the example of FIG. 3, there is no response to one key pressing operation, and a combination of two or more key pressing operations (combination within four keys and Various functions such as cursor movement are assigned only to combinations of four keys and other keys. The four keys are selection keys in the character input means (for example, "A", "H", "O",
"V").

Further, even if only one key "I" at the center of the cross shape is provided as shown in FIG. 5B, this key "I" itself and this key "I" and other keys are provided twice. Many functions can be assigned to the above combinations of key pressing operations. This key "I" may be a conventional "#" key or "* (different from the actual shape but used for convenience)" key in the push-type telephone.

FIG. 6 shows another example in which the selection key in the character input means according to the present invention and the cross-shaped key for cursor movement operation are combined. In FIG. 6 (A), ten kana characters in the column A are selected as selection keys, and five of them are selected, “A”, “ka”, “sa”, “ta”, and “na”.
Are arranged side by side in an I shape, and the other five are "ha", "ma",
The "ya", "ra", and "wa" form a cross-shaped key. Here, note the selection key in the kana character input means. If five vowels of "A", "I", "U", "E", and "O" are used as the selection keys, The number of selection keys is smaller than that of the selection keys, but as shown in Table 3, most of the combinations with the numeric keys are used for character input. There is no room to allocate other functions. On the other hand, when the row is used as the selection key, the number of selection keys is large (there are only five more), but as shown in Table 4, it is not used in the combination of the selection key and the numeric key. Many parts are left, which is advantageous in that various other functions can be individually assigned. This kana character input means using this row as a selection key will be most suitable for a user who is not good at inputting romanized characters and desires kana character input.

In FIG. 6B, four keys "A", "H", "O", and "V" are selected as selection keys of the English character input means, and these are arranged in a T shape. Functions such as cursor movement operations are assigned to two or more key pressing operations. As described above, the plurality of selection keys appropriately selected for the character input means according to the present invention are selected in consideration of the external shape, design, usability, etc. of the device to which the selection keys are applied, and the cross shape, the T shape, the U shape , I-shape, L-shape, and combinations thereof can be placed on the keyboard.

FIG. 7 is an example of another keyboard to which the present invention is applied. In this example, five keys "A", "I", "U", "E", and "O" are selected as the selection keys of the character input means. As described above, if these five keys are used as selection keys, the number of unused parts in combination with the numeric keys is small and many functions cannot be assigned. Therefore, in order to supplement this, a key "V" is provided, and this "V" and "A", "I",
The "u" and the "e" form a cross-shaped key. In this case, the key "V" is not the selection key of the character input means. The view of FIG. 7 is the same as that of FIG. Like this one
By supplementing the two keys "V", it is possible to assign functions that are substantially comparable to the keyboard of FIG. Further, in FIG. 7, in order to make it easy to distinguish a desired numeric key that is pressed after the selection key at the time of inputting characters, “A” and “A” are respectively placed to the left of the numeric keys “1” to “0” on the keyboard.
"Mo" ... "wa" are written.

FIG. 8 shows an example of still another keyboard to which the present invention is applied. In this example, five keys “A”, “H”, “O”,
Select “V” and “X”, and arrange them side by side in an I shape, and assign various functions to the key pressing operation of two or more combinations in the same manner as the above examples. There is. The way to see this figure is the same as in the previous example. This example assumes that the applied device has a plurality of display screens, and each of the display screens has a page function having a plurality of pages. Therefore, as a characteristic function set on the keyboard, a combination of the selection key "A" and the numeric key "9", the selection key "H" and the numeric key "0", and the selection key "X" and the numeric key "7". On the other hand, each display screen (for example, the individual indicators of each display screen are A, H, and X)
The page selection function of is assigned. An example of a comprehensive electronic calculator having such a display screen will be described later.

FIG. 9 is a schematic diagram showing a pager 22 with a calling function, which is an example of an electronic apparatus to which the present invention is applied. This pager 22 has multiple display screens,
These are the message display screen section 23, the address display screen section 24, the destination telephone number display screen section 25, the message attributes.
(Open or secret) display screen section 26, and secret character (displayed only in case of secret) display screen section 27
Consists of Further, the pager 22 is a keyboard 1 including four selection keys "A", "H", "O", and "V" and number keys "0" to "9" arranged in an inverted T shape. It is equipped with.

The pager 22 with the calling function shown in FIG.
Using the four selection keys and the numeric keys, the message is displayed on the message display screen section 23, the destination address is displayed on the address display screen section 24, and the destination telephone number is displayed on the destination telephone number display screen section 25. Respectively. Next, whether the message is open or secret is input to the message attribute display screen section 26. In FIG. 9, it is displayed as a secret. Then, in this case, the personal identification character is input to the personal identification character display screen portion 27. After these inputs are completed, the execution operation is performed. On the other hand, the person to whom the message is sent is received by a telephone or a facsimile equipped with a similar display screen and a keyboard for inputting characters, or by connecting such a telephone with a television. At that time, if the addressee is at home,
A message is displayed when a predetermined secret character is input, but the received message cannot be displayed when the addressee is absent.

FIG. 10 is a diagram showing the keyboard section 1 of the pager 22 with the calling function of FIG. 9 together with the assigned functions. Functions include cursor movement, execution, deletion, lowercase letters, and input of various symbols. In addition, a storage number display field is provided in each display screen of the pager 22 with a calling function, the storage is executed after the input, and the storage content is called by inputting the storage number, and the content is edited if necessary. It is also possible to adopt a configuration in which it is executed later.

Next, regarding the electronic calculator to which the character input means according to the present invention can be suitably applied, the present invention provides another useful function that can be incorporated together with the character input means, that is, a new trial calculation function. FIG. 11 is an external view showing a first example of an electronic calculator having a trial calculation function according to the present invention. A keyboard portion of a general electronic calculator has at least numeric keys, function keys for calculation, and the like. The basics of the trial calculation assumed in the present invention will be briefly described. First, the electronic calculator executes a predetermined calculation process to obtain a numerical value as a result, and then repeats the same calculation again to check whether the numerical value is correct or not. If it agrees with the value of, the correct result can be confirmed, that is, the trial calculation is completed. The conventional trial calculation operation is
Although it was performed by recording the first result by writing it in a memo or the like, the present invention realized to incorporate such an empirical calculation function into an electronic calculator.

The electronic calculator having a trial calculation function according to the present invention shown in FIG. 11 has two display screens, a first display screen 9 and a second display screen 10. Further, an initial display / combined key 1 for executing initialization and display retention of the first display screen 9 and the second display screen 10 on the keyboard.
Equipped with 2. Although the conventional initialization key only initializes the display screen, the initial display / combined key 12 in the present invention has the function of initializing both display screens and the function of holding the display content of the first display screen 9. It also has
The trial calculation operation using the initial display / combined key 12 will be described below.

First, both the first display screen 9 and the second display screen 10 are initialized by the first key depression operation of the initial display / combined key 12. At this time, both display screens are in a calculable state. Then, after the first calculation is completed, the result of the first time is displayed on both the first display screen 9 and the second display screen 10. At this time, by performing the second key pressing operation of the initial display / combined key 12, only the display of the first display screen 9 among the first calculation results displayed on both display screens is retained. At the same time, the second display screen 10 is initialized so that it can be calculated.

Then, after performing the trial calculation on the second display screen 10, the trial calculation result displayed on the second display screen and the first result held on the first display screen 9 are If they are equal, the calculation was correct and the trial calculation is completed. After that, the operation returns to the first key pressing operation of the initial display / combined key 12, the both display screens are initialized and calculation is possible, and the process proceeds to the next calculation. In this way, the function of the initial display / combined key 12 is cycled with two key presses as one cycle.

Next, a second example of the electronic calculator having the trial calculation function will be described with reference to FIG. In this second example, a first display screen 9 having an appearance similar to that of the first example is displayed.
And a second display screen 10. Further, an initial display / combined key 12 having a function different from that of the first example and for executing initialization of the first display screen 9 and storage of display contents of the first display screen 9 is provided. Further, although not shown, a storage unit for storing the display content of the first display screen 9 is built in.

The basic function of the initial display / combined key 12 in the second example will be described. If the display content of the first display screen 9 and the current storage content of the storage unit do not match when the key press operation of the initial display / combined key 12 is executed, the content of the first display screen 9 is stored. At the same time memorized in the department
The display screen 9 of is initialized. On the other hand, key 1 for initial display
When the key press operation of 2 is executed, the first display screen 9
If the display content of and the storage content of the storage unit match,
The contents of the first display screen 9 are stored in the storage unit, and at the same time, the first display screen 9 is initialized and the matched contents are displayed on the second display screen 10. The trial calculation operation using the initial display / combined key 12 will be described below.

At the time when the previous calculation and trial calculation are completed,
The previous calculation result is stored in the storage unit, and the first display screen 9 is initialized and is in the calculation enabled state. At this time, the previous calculation result should be displayed on the second display screen 10. First, the first calculation is executed on the first display screen 9. After the first calculation result is displayed on the first display screen 9, the initial display / combined key 12 is pressed. As long as it does not happen to be the same numerical value as the previous calculation result (note that even if it happens to be the same value, no inconvenience will occur due to the operation of the trial calculation function of the present invention) and the contents stored in the storage unit and Since the display contents of the first display screen 9 do not match, the contents of the first display screen 9 (that is, the first calculation result) are stored in the storage unit. At the same time, the first display screen 9
Is initialized and is in a computable state. Subsequently, the trial calculation is executed on the first display screen 9. After the trial calculation result is displayed on the first display screen 9, the initial display / combined key 12 is pressed. If the calculation is performed correctly and the first calculation result stored in the storage unit matches the trial calculation result of the first display screen 9, the trial calculation result of the first display screen 9 is stored in the storage unit. At the same time, the first display screen 9 is initialized. The operation up to this point is the same as the operation when the content of the storage unit and the content of the first display screen 9 do not match, so the same processing means can be used. Here, when the content of the storage unit and the content of the first display screen 9 match, the first display screen 9
The operation of displaying the display contents of the above on the second display screen 10 is added. Then, since the first display screen 9 is in a calculable state, the process proceeds to the next calculation. In this way, the second display screen 10 displays the previous (experimental) calculation result, and the user can visually confirm this value at any time for reference.

The effect of the second display screen 10 in the second example of the electronic calculator with an empirical calculation function is that, as shown in FIG. 12, the second display screen 10 is divided into a plurality of screens 11 (a, b, respectively). It is particularly effective when extended to ().
In this case, if the display contents of the first display screen 9 and the contents of the storage unit match when the initial display / combined key 12 is pressed,
The contents of the first display screen 9 are stored in the storage unit and the first display screen 9 is initialized, and the contents of the first display screen 9 are displayed on the display screen c. And according to it,
The contents displayed on the display screen c are sequentially moved to the display screen b, and the contents displayed on the display screen b are sequentially moved to the display screen a, and the display contents of the display screens c, b, and a are substantially sequentially moved. (The contents displayed on the display screen a disappear). The following Table 11 is a table showing a series of key pressing operations for the initial display / combined keys, the display contents of the display screens 9, a, b, and c, and the storage contents of the storage unit.

[0088]

[Table 11]

In Table 11, starting from the complete initialization state (state in which the contents of all display screens and storage units are "0"), 4
Seed calculations A, B, C, and D are performed, but each is calculated twice, including empirical calculations. It should be noted here that only the results after the trial calculation are displayed on the display screens a, b, and c. If the test calculation result does not match the first result in the middle, the same calculation is repeated again (or twice or more), but even in that case, the contents of the storage unit and the display screen 9 are finally displayed. The result of the display screen 9 is moved to the display screen c only when the contents match with the above.

According to such a display screen configuration, the user can visually check the experimental results of the series of calculations up to now, and can refer to these values, which is very efficient. Is. Such a usage situation occurs in various places in various businesses that actually use the electronic calculator. For example, when performing a series of calculations, it is desirable to incorporate past calculation results into the current calculation. Conventionally, past calculation results are stored in a given storage unit of an electronic calculator, and a numerical value stored by a predetermined calling operation is taken out at a time when it is necessary. Often, I forget the calling operation or forget what numerical value was stored in which storage section.
It was very difficult to use. On the other hand, in the second example of the electronic calculator with an empirical calculation function according to the present invention, the past calculation results are always displayed in order from the newest one, so that it can be visually confirmed at any time, and if there is a necessary numerical value. It can be used immediately.

FIG. 13 is a total electronic calculator 8 incorporating both the character input means and the trial calculation function according to the present invention described above.
It is a figure which shows the schematic external appearance of the 1st example of. On the keyboard, there are three display call keys "A", "Q", and a selection key (indicated by ◇) in any of the above character input means, a conventional numeric key and a function key for calculation. "R"
Is arranged. The three display call keys will be described later. Regarding the display screen, in addition to the main display screen 9 for actually performing the calculation processing, a plurality of display screen groups characteristic of the integrated electronic calculator 8 are provided. These display screens are
It is provided with an A group (13a to 13g) that displays an arbitrary numerical value, a Q group (14a to 14d) that displays an arbitrary mathematical expression, and an R group (15a to 15c) that displays a trial calculation result of a past calculation. Of course, this configuration is an example.

The display screen R group (15a to 15c) is shown in FIG.
It corresponds to the display screens ac of the trial calculation result described in 2. The display screen R group, the main display screen 9, and a storage unit (not shown) that stores the display contents of the main display screen 9 realize the test calculation function and the display of the test calculation result thereof described in FIG. .

As for the numerical value display screen A group and the mathematical expression display screen Q group, as described with reference to FIG. 12, the conventional numerical value or mathematical expression storage function is complicated to call and the stored contents are always grasped. It was provided to improve this because it was difficult to keep. That is, numerical values, mathematical expressions, etc. that may be frequently used are always displayed on each display screen. Next to these display screens is an individual sign 1 for that screen.
6 (A1, A2 ... A7, Q1, Q2 ... Q4, R1 ...
R3) is indicated in each case. The user can call the contents of the display screen to the main display screen by inputting the individual marker from the keyboard. The above-mentioned display call keys of "A", "Q", and "R" provided on the keyboard are used for this call operation. That is, a specific individual sign can be designated by a combination of these display call keys and numeric keys. Since the individual marker on each display screen and its display content can be visually checked at all times, the user can easily call the required numerical value or mathematical formula. Also, regarding the mathematical formulas displayed on the display screen Q group, these numerical formulas are added to the numerical display screen A when calling.
It is also possible to incorporate and execute an arbitrary numerical value of the group and a numerical value of the trial calculation result of the numerical value table screen R group, and display the result on the main display screen 9.

Further, FIG. 14 shows an example of a keyboard when character input is not necessary in the integrated electronic calculator 8 as shown in FIG. In this case, it is sufficient to arrange the display call key in addition to the conventional keys.

FIG. 15 is a diagram showing a schematic appearance of a second example of the integrated electronic calculator 8 incorporating both the character input means and the trial calculation function. The display screen group includes an A group (13a to 13g) that displays an arbitrary numerical value, an H group (14a to 14d) that displays an arbitrary mathematical expression, and an X group (15a to 15c) that displays a trial calculation result of past calculation. ) Consists of. As a character input means, "A", "H", "O", "V" on the keyboard,
And five selection keys consisting of "X" are arranged laterally in an I shape. These selection keys are also used as display call keys for the above-mentioned display screens. When used as a display call key, for example, by inputting "A3", "350" of the numerical display screen 13c is displayed on the main display screen 9, and "H" is displayed.
If you enter "2", each numerical value (that is, X is 230 is displayed in the mathematical formula (XB + ZF) displayed on the mathematical formula display screen 14b.
0, B is 280, Z is 1990, and F is 650) are incorporated to execute the calculation, and the result (that is, 1,937,500) is displayed on the main display screen 9. In this way, any numerical value of the A group and / or an experimentally calculated numerical value of the X group can be executed by any mathematical expression of the H group.

The keyboard used in the example of FIG. 15 is shown in FIG.
The keyboard settings shown in are used, but the keyboard is not limited to this.

Regarding the operation of the display call key, the display may be called only by inputting "A4", or the display is called after inputting the "=" key after "A4". You may do it.

Of course, in addition to the select key, display call keys such as "A", "Q", and "R" are provided as in the above example, and individual indicators R1 to R7 are provided on each display screen. Good.

In the second example of FIG. 15, in each display screen,
An abbreviated character registration unit 17 for schematically explaining the display contents is provided, and an arbitrary character can be input and displayed using the character input means. For example, "strawberry" is displayed on the display screen A1. FIG. 16 is a flow chart showing the contents of each display screen of FIG. 15 and the method of inputting and correcting the abbreviated character registration unit in each display screen. Basically, the same method can be used to input the examples shown in the other figures. In addition, it is optional to set the function of calling the characters of the abbreviated character registration unit 17 to the main display screen 9 (for example, pressing this key twice as described above the "V" key in FIG. 8). is there.

In FIG. 15, the part indicated by reference numeral 19 is the page number display portion. In this example, the number of pages is two, and each page is distinguished by using an underline. That is, the page without underline is the first page, and the page with underline is the second page. The page number display section is not limited to underlining, and various forms such as a numerical value indicating the number of pages (before or after the abbreviated character registration section), an appropriate display mark, or an inverted display of the first character of the abbreviated character registration section are possible To be The number of pages attached to each screen can be set arbitrarily.

The page operation can be executed by a combination of two keys as described in the example of the keyboard shown in FIG. For example, when the operation mode is the page circulation mode and the selection key "A" on the keyboard of FIG. 8 is pressed followed by the numeral key "9", the page of each display screen of the group A is moved to the next page. When this is repeated, each page is cyclically displayed one after another. A key function for reversing the circulation direction may be set.

To further note the example of FIG. 15, for the trial calculation result display screens X groups 15a to 15c, the same trial calculation function as described in FIG. 12 is realized together with the main display screen 9 and the calculation result storage unit. However, these display screen X groups 15a to 15c can be used for inputting and displaying arbitrary numerical values, and execution with mathematical expressions. That is, the same use as the numerical display screen group A groups 13a to 13g is possible. An example of a method of inputting arbitrary numerical values to the display screen X groups 15a to 15c will be given. First, when the key "H" is pressed (w) twice and "X1" is input according to the input method for each display screen shown in the flowchart of FIG. 16, the cursor appears at the right end of the display screen 15a. If there is a numerical value already displayed, delete it by pressing the key "A" twice, enter the desired numerical value, and press the key "H" twice again to display the main cursor. Return to screen 9. As another input method, first, a desired numerical value is input on the main display screen 9 and the initial display / combined key 12 is pressed, then a numerical value is input again and the initial display / combined key 12 is pressed. A desired numerical value is displayed on the display screen 15c according to the operation of the trial calculation function described above. Further, if the initial display / combined key 12 is pressed twice, the desired numerical value moves to the display screen 15b, and further pressing twice moves to the display screen 15a. In this way, the arbitrary numerical values displayed on the display screen X groups 15a to 15c of the trial calculation results can be incorporated into the mathematical expressions X, Y, and Z of the display screen group H group.

FIG. 17 shows a small communication device 20 according to the present invention, which has a plurality of display screens 13a to 13g having an individual marker 16 and an abbreviated character registration unit 17 and having a page function such as a page number display 19. This is an example. The plurality of display screens 13a to 13g correspond to the numerical value display screen group in the examples shown in FIGS. 13 and 15. In this example, another display unit is provided especially after the abbreviated character registration unit, and for example, the name or company name of the other party is input and displayed. A telephone number, for example, is entered and displayed in the numerical portion. Further, the individual indicator 16 on each display screen may be designated to call up the characters in the abbreviated character registration unit 17 on the main display screen 9 to execute automatic dialing. Further, it may be set so that the automatic dialing can be executed even when the characters of the abbreviated character registration unit 17 are not in the display state and are on another page. It should be noted that the characters input to the abbreviated character registration unit 17 are preferably nicknames or abbreviations that are easy to remember.

In addition to such a small communication device, the above-mentioned functions can be applied. For example, by inputting and displaying many command items in the abbreviated character registration unit 17 and calling them on the main display screen 9, it is possible to configure an electronic command device device that executes the commands.

FIG. 18 is a diagram showing a schematic external view of an example of the total order electronic calculator 21 to which the present invention is applied. In the numerical value display screen groups 13a to 13l of this example, the product name is input and displayed in the abbreviated character registration unit 17, and the list price and quantity thereof are input and displayed as numerical values. Formula display screen group 14
The mathematical expressions input and displayed in a and 14b are, for example, when the quantity of ordered products is input, the total calculation is executed and the result is displayed on the main display screen 9. In this example, the page operation of each of the numerical display screens of the A group and the X group may be performed with one page operation key. Furthermore, a slip number column may be provided on any of the display screens for input and display, and after saving these, the slip number may be input to call it. Further, the total order electronic calculator 21 may be provided with a print output terminal so as to be connectable to a printer, and the slip number, the ordered product, and the total numerical value may be printed.
This total order electronic calculator 21 may be set so as to be used as a terminal for ordering or sales management. Therefore, the date is input and displayed on any display screen, and a connection terminal to the host computer is also provided. FIG.
In the total small electronic device shown in FIG. 3, FIG. 15, FIG. 17, and FIG. 18, only the combination with the specific keyboard is shown, but these are examples and other keyboards according to the present invention may be incorporated. It is possible.

[0106]

In the character input means and the keyboard to which the character input means according to the present invention is applied, a small number of selection keys selected based on the characteristics of a given language are arranged on the keyboard.
Characters are input by a combination of a pair of key pressing operations of these and numeric keys, and a specific key group is arranged in a cross shape or the like, and these are configured to function only for a pair of key pressing operations. Therefore, sufficient character expression and a very wide range of function settings can be realized even in a small electronic device that is required to be configured with a small number of keys, without a cumbersome switching operation such as a conventional shift key or function key.

In the trial calculation function of the electronic calculator according to the present invention, if only the trial calculation results are displayed and there are a plurality of display screens, the past trial calculation results are sequentially moved for each calculation. Since the information is displayed, not only is there no useless display, but also the displayed results can be visually confirmed and can be referred to immediately.

In the integrated electronic device in which the respective configurations of the present invention as described above are integrated, characters are efficiently input to a plurality of display screens to constantly display useful information, and Since the contents can be visually confirmed at any time, it is possible to freely call up a desired one for processing. Using the specific example of FIG. 15, in the formula of the H group, A
A numerical value (constant) of the group and an empirically calculated numerical value (variable) of the X group can be incorporated, and the calculation can be executed to realize a comprehensive electronic calculator.

As described above, the present invention remarkably improves the usability in a small electronic device, and by applying the present invention, the range of use of various small electronic devices will be greatly expanded.
