Data indicating the atomic number and atomic weight are registered. Further, for each element, there is a homologous relationship between an address indicating a peripheral element in the periodic table, that is, an element located at the top, bottom, left, and right (peripheral element address) and an address indicating an element having the same period (same element address). Addresses indicating the elements (homologous element addresses) are registered in association with each other.

Next, the operation of this embodiment will be described. First, the overall processing of the display device will be described with reference to FIG.
This will be described with reference to the flowchart shown in FIG. First,
When the menu key 12a of the key input unit 12 is pressed to select an operation mode (step A1), the CPU 10
Controls the display drive circuit 20 to display a mode selection screen on the display unit 18 (step A2). The mode selection screen displays a list of selectable operation modes, that is, items for selecting any of a chemical calculation mode, a graph mode, a program mode, and the like.

When the mode selection screen is displayed (step A3), any mode can be arbitrarily selected by operating the cursor key 12d or the like (step A4). Here, when an arbitrary mode is selected and the execution key 12e is pressed (step A5), the CPU
10 sets the designated mode to an executable state,
Display the initial screen of the set mode (step A
6, A7).

The CPU 10 uses the input data after the mode setting in the processing in the setting mode. That is, when the chemical calculation mode is set (step A8), the chemical calculation mode processing is executed using the input data (step A9), and when the sgraph mode is set similarly, Graph mode processing (steps A10 and A11), and program processing (step A1) when the program mode is set
2, A13) are respectively executed.

Since the graph mode processing and the program mode processing are not related to the present invention, detailed description will be omitted. Next, regarding the chemical calculation mode in the present embodiment, the flowchart shown in FIG. 6, and FIGS.
This will be described with reference to an example of the display screen shown in FIG.

In the chemical calculation mode, characters (alphabets and numbers) input by the character keys 12c are treated as characters representing elemental symbols (and molecular formulas), input and displayed, and a calculation formula for calculating the atomic weight is set. Then the atomic weight can be determined.

Here, when an alphabet is inputted and instructed by operating the character key 12c (step B1), C is input.
If there is no undecided character immediately before (step B2), the PU 10 inputs the designated character as an uppercase letter (step B4), stores the data of this character in the undecided character register 22c of the RAM 22, and inputs the data. The character pattern of the input character is stored in the display register 22a.
The display drive circuit 20 is controlled to display on the display unit 18 (step B5).

The CPU 10 also stores the periodic table management table 24a in the ROM 24 based on the input characters (element symbols).
(Step B6), and the presence or absence of an element corresponding to the input character is determined (step B7). CPU10
When the corresponding element can be retrieved from the periodic table management table 24a, the atomic weight corresponding to this element is obtained, and the pattern for displaying the atomic weight is stored in the display register 22a together with the input character pattern and displayed.

Further, the CPU 10 registers the atomic weight corresponding to the input element in the calculation formula for calculating the atomic weight, stores the calculation result in the calculation formula register 22g of the RAM 22, and displays the calculation formula (step B8).

FIG. 7A shows an example of a display screen when the alphabet "N" is input. For the letter "N", the symbol "N" for the element nitrogen
Therefore, the atomic weight “(14)” of nitrogen is added to the character of the element symbol “N” indicating the undetermined state. Also, “(14)” is displayed at the bottom of the screen as a formula for calculating the atomic weight (only the atomic weight is shown because only the element symbol of one element is input).

Next, in the same manner, when the alphabet is input by the operation of the character key 12c (step B).
1) Since there is an undecided character "N" immediately before (step B2), the CPU 10 inputs the designated character as a lowercase letter (step B3) and converts the data of this character into RA.
M22 is stored in the undetermined character register 22c and the character pattern of the input character is stored in the display register 22c.
a is stored and displayed (step B5).

That is, in the case where an element symbol is represented by two characters, since the second character is always lower case, if characters are consecutively input (the previously input character is not determined), In, the character input later is determined to represent the element symbol by the combination with the character input earlier, and the element symbol is automatically generated as a lowercase letter to generate the element symbol.

Accordingly, the character keys 12c of the key input section 12
However, basically, a single key is used to switch the state by operating a special function key (such as a “shift” key for changing an input mode) to input uppercase and lowercase letters. Even if there is, in the chemical calculation mode, the correct element symbol can be easily input by inputting characters without being aware of the input mode (without performing the switching operation).

FIG. 7B shows an example of a display screen when the alphabet "A" is input after the alphabet "N". As for the alphabet "A", there is an undecided character "N", so it is input as a lowercase letter "a", and in combination with the previously input character "N", the element symbol "Na" of sodium of the element It is said.

The CPU 10 searches the periodic table management table 24a of the ROM 24 based on the element symbols represented by two characters (step B6), and determines whether or not there is an element corresponding to the input character (step B6). B7).

The CPU 10 controls the periodic table management table 24a.
Since the element “Na” can be searched as a corresponding element from, the atomic weight “(23)” of sodium is added to the character of the element symbol “Na” and displayed (FIG. 7B).
In addition, “(23)” is displayed at the lower part of the screen instead of the previously displayed “(14)” as a formula for calculating the atomic weight (in the state where only the element symbol of one element is input). Therefore, only the atomic weight is shown).

Here, the enter key 12g of the key input section 12
Is input (step B2).
4) The input element symbol that is currently in an undetermined state can be set to the determined state (step B25), but the correspondence based on the arrangement of the periodic table of the elements based on the input element symbol. Can easily input and display the element symbol of another element.

That is, the search key 12 of the key input unit 12
f, a search execution instruction is input (step B
9) If there is an element symbol that has been input (step B10), the CPU 10 obtains peripheral (upper, lower, left and right) element symbols in the periodic table of the element symbol (step B11).
That is, the element in the periodic table management table 24a is searched using the element symbol that has been input, the peripheral element address of this element is obtained, and the element indicated by the address registered in the peripheral element address is acquired as the peripheral element. CPU10
Causes the search result register 22f to store the element symbol obtained from the peripheral element address.

The CPU 10 controls the periodic table management table 24a
And the element symbols of the peripheral elements stored in the search result register 22f and the four sides centered on the input and displayed element symbols, that is, the respective element symbols of the peripheral elements, The symbols are displayed according to the positional relationship (up, down, left and right) registered in the periodic table management table 24a (step B12).

FIG. 7 (C) shows the element symbol “N
An example of element symbols of peripheral elements displayed when search execution is instructed for “a” is shown. As for the element sodium “Na”, as shown in FIG. 3, the peripheral element addresses “3, 19,
10, 12 "are registered. Accordingly, the element indicated by the peripheral element address “3, 19, 10, 12”, that is, lithium “Li”, potassium “K”, neon “Ne”, and magnesium “Mg” is replaced with sodium “N” indicated.
Each element is displayed at a predetermined position as an element located above, below, left, and right of “a”.

As shown in FIG. 7 (C), when an instruction in one of the up, down, left and right directions is inputted by the cursor key 12d of the key input section 12 in a state where the element symbols of the peripheral elements are displayed (step S1). B13, B14), the CPU 10 operates the periodic table management table 24 according to the input direction instruction.
Based on the positional relationship registered in a, the element symbols displayed in the up, down, left, and right positions with respect to the inputted element symbols are changed (step B15).

That is, the CPU 10 changes the input element symbol in the undetermined state to the element symbol of the element corresponding to the direction designated by the cursor key 12d, and the peripheral element address corresponding to the changed element. See
As described above, the element symbols of the corresponding elements are displayed at predetermined positions.

FIG. 7D shows a display example of peripheral elements when a rightward instruction is input in the state shown in FIG. 7C. When a rightward instruction is input, the CPU
10 indicates that the element on the right side in the periodic table of the element sodium “Na” can be determined to be magnesium “Mg” from the address corresponding to the right of the peripheral element address of sodium “Na”, and the element symbol in an undetermined state is determined. Change to "Mg". In addition, the CPU 10 determines the vertical and horizontal element symbols of magnesium “Mg” in the periodic table, namely, beryllium “Be”, calcium “Ca”, sodium “Na”,
Aluminum “Al” is displayed at predetermined positions.

In this way, the surrounding element symbols are displayed by the instruction with the search key 12f for the already entered element symbols, and the directions in the up, down, left and right directions are arbitrarily given by operating the cursor keys 12d. Other element symbols can be displayed according to the positional relationship of the arrangement of each element in the periodic table. That is, in the positional relationship of the arrangement in the periodic table, the elements in the upper and lower positional relationship are:
It means that the elements are included in the same group, and the elements that are in the left-right positional relationship mean that they have the same period. Therefore, successively call the element symbol of the element related to the group and period, input the desired element symbol,
Can be displayed.

When an instruction for confirmation is input by the confirmation key 12g of the key input section 12 with the desired element symbol displayed (step B24), the CPU 10
Stores the input element symbol in the undetermined state, that is, the element symbol at the cursor position, in the determined character register 22d.
In a fixed state, and changed to a display form indicating the fixed state and displayed (step B25).

Further, the CPU 10 registers the atomic weight of the element corresponding to the determined element symbol in a calculation formula for calculating the atomic weight, stores it in the calculation formula register 22g of the RAM 22, and displays the calculation formula (step B8). ).

In the above description, the periodic table management table 2 is based on the entered element symbols in an undetermined state.
Although the peripheral elements are searched for and displayed with reference to 4a, the peripheral elements may be searched for and displayed based on the element symbols that have been input and are in a confirmed state.

For example, an instruction to determine the element symbol “Na” in the undetermined state as shown in FIG. 7B is input by the determination key 12g, and as shown in FIG.
It is assumed that the element symbol “Na” is displayed in a determined state. In this state, the processing target (cursor position) has been changed to the next character input position.

When the display of the peripheral element is instructed by the search key 12f, the CPU 10 determines that the input element symbol does not exist at the current character position to be processed. Determine the presence or absence. here,
The presence / absence of the input element symbol is determined not only for the element symbol in the undetermined state but also for the element symbol in the determined state stored in the determined character register 22d.

In the example shown in FIG. 8A, there is an element symbol "Na" in a determined state, and therefore, based on the inputted element symbol "Na", the periodic table management table 24a
Is searched, and the element symbols of the peripheral elements are searched and displayed.

FIG. 8B shows a state in which peripheral elements corresponding to the element symbol “Na” are displayed. FIG. 8 (B)
As shown in, the same element symbol “Na” as the already entered element symbol “Na” is displayed as an undetermined state at the current character position to be processed, and the element symbols of the peripheral elements corresponding to this element symbol "Li""K""Ne""Mg"
Are displayed at predetermined positions. In addition,
Since the display control of the element symbols of the peripheral elements is performed in the same manner as described above, detailed description will be omitted.

In the state shown in FIG. 8B, when a rightward designation (six times) is input by the cursor key 12d, as shown in FIG. 8C, the chlorine element is determined based on the arrangement of the periodic table. The symbol "Cl" is displayed.

Here, when the confirmation of the element symbol "Cl" in the undetermined state is instructed by the determination key 12g, the element symbol "Cl" is changed to the defined state as shown in FIG. 8D. Represents the molecular formula “NaCl”. Further, the CPU 10 registers the atomic weight corresponding to the element of the determined element symbol in a calculation formula for calculating the atomic weight, and
The calculation formula is stored in the calculation formula register 22g of M22 and the calculation formula is displayed. Since the element symbol “Na” has been input earlier, “(23) + (35) = (58)” is displayed as a calculation formula for adding the atomic weight “(35)” of the element “Cl” in the lower part of the screen. It is displayed (step B8).

In the above description, the periodic table management table 24a is referred to based on the entered element symbols,
Although the peripheral elements are searched and displayed, other elements having the same group or period can be searched and displayed in a list based on the input element symbols.

First, a case where another element having the same relationship as the period is searched for and displayed as a list will be described. For example,
In the state where the element symbol “Na” in the final state is displayed as shown in FIG. 8A, when an instruction is input by the cycle designation key 12h of the key input unit 12 (step B1).
6) The CPU 10 determines that the cycle designation mode has been designated, and sets the cycle designation mode in the designated mode register 22.
e, and it is determined whether or not there is an element symbol that has been input (step B17).

If there is an input element symbol, the CPU 10 obtains an element symbol of an element included in the same cycle as the element of the element symbol. That is, the CPU 10 searches for the element in the periodic table management table 24a based on the element symbol that has been input, obtains the same-period element address of this element, and determines the same element indicated by the address registered in the same-period element address. Obtained as elements included in the cycle. The CPU 10 causes the search result register 22f to store the element symbol obtained from the same period element address.

The CPU 10 controls the periodic table management table 24a
Are displayed in a list at the top of the display screen, for example, at the top of the display screen (step B18).

FIG. 9 (A) shows the element symbol “N
13 shows an example of a list display of same-period elements displayed when a period is designated for “a”. As for the element sodium “Na”, as shown in FIG. 3, the same period address “12, 13, 1” in the period table management table 24a.
4, 15, 16, 17, 18 "are registered. Therefore, the same period address “12, 13, 14, 15, 16,
17, 18 ”, ie, magnesium“ M ”
g ", aluminum" Al ", silicon" Si ", phosphorus" P ", sulfur" S ", chlorine" Cl ", argon" Ar "
Are listed at the top of the display screen. In the present embodiment, the already entered element symbol “Na” is also displayed in the list of the same-period elements (therefore, the address of the element corresponding to the same-period element address in the periodic table management table 24a is also displayed). May be included).

While displaying the list of elements of the same period, the CPU 10 displays a cursor for selecting an element symbol from the list (step B19). In the example shown in FIG. 9A, the same element symbol “N”
The cursor is displayed at "a".

Although the processing procedure is omitted in the flowchart shown in FIG. 6, when an instruction to select a specific element symbol from the list of the same-period elements is input, CP
U10 performs a selection process according to the instruction.

That is, when there is an input from the cursor key 12d, if the CPU 10 is in a state where a list of the same period elements is displayed (if the period specification mode is set in the specification mode register 22e), the CPU 10 specifies The processing according to the performed direction is performed.

When the horizontal direction is designated in the cycle designation mode, the CPU 10 determines that the operation is to select an element symbol from the same cycle list display, and moves the cursor of the same cycle element list according to the designated direction. .

The cursor is moved to an arbitrary element symbol,
When the confirmation is instructed by the confirmation key 12g, the CPU 10
Determines the character (element symbol) at the cursor position in the same period list display and displays it at the original character input position.

When the up / down direction is designated in the cycle designation mode, the CPU 10 determines that the operation of changing the contents of the same cycle list display to the contents of another cycle is the operation of changing the cycle in the designated direction. Switches to the same cycle list display. That is, when the upward or downward direction is designated, the CPU 10 refers to the periodic table management table 24a based on the element symbol at which the cursor currently displaying the same periodic list is located, and displays the peripheral element corresponding to the corresponding element. From the address, the address of the element located above or below according to the designation is obtained. Then, the CPU 10 obtains the same-period element address corresponding to the element indicated by the upper or lower address in the peripheral element address, and displays the specified upper or lower same-period list.

FIG. 9B shows a display example of the list of the same-period elements when the designation with the upper cursor is input in a state where the list of the same-period elements is displayed as shown in FIG. 9A. I have. In this case, the CPU 10 determines the element “Li” from the peripheral element address “3” located above the element symbol “Na”, and obtains the same-period element address “4, 5, 6, 7” corresponding to this element “Li”. , 8, 9, 10 "(and" 3 ").

Next, a case will be described in which another element having the same relationship as the period is searched for and displayed in a list. For example,
When an instruction with the group designation key 12i of the key input unit 12 is input in a state where the element symbol “Na” in the final state as shown in FIG. 8A is displayed (step B20).
The CPU 10 determines that the family designation mode has been designated, sets the family designation mode in the designated mode register 22e, and determines whether there is an element symbol that has been input (step B21).

If there is an input element symbol, the CPU 10 obtains an element symbol of an element included in the same group as the element of this element symbol. That is, the CPU 10 searches for the element in the periodic table management table 24a based on the element symbol that has been input, obtains the cognate element address of this element, and assigns the element indicated by the address registered in the cognate element address to the same group. Obtain as contained elements. The CPU 10 retrieves the element symbol obtained from the homologous element address in the search result register 22f.
To memorize.

The CPU 10 controls the periodic table management table 24a
Are displayed in a list on the left side of the display screen, for example, in the left part of the display screen (step B23).

FIG. 9 (C) shows the element symbol “N
13 shows an example of a list display of homologous elements displayed when a period is designated for “a”. Elemental sodium "N
As for “a”, as shown in FIG. 3, in the periodic table management table 24a, the family addresses “1, 3, 19, 37,
55, 87 "are registered. Accordingly, the elements indicated by the same-period address “1,3,19,37,55,87”, ie, hydrogen “H”, lithium “Li”, potassium “K”, rubidium “Rb”, cesium “Cs”, and francium “ "Fr" is listed at the top of the display screen. In the present embodiment, the element symbol “N
"a" is also displayed in the list of elements of the same period (thus,
The address of the corresponding element may be included in the homologous element address in the periodic table management table 24a.)

Further, the CPU 10 displays a cursor for selecting an element symbol from the list while displaying the list of homologous elements (step B23). In the example shown in FIG. 9C, the element symbol “Na” is the same as the element symbol already input.
The cursor is displayed on.

Although the processing procedure is omitted in the flowchart shown in FIG. 6, when an instruction for selecting a specific element symbol from a list of homologous elements is input, the CPU
10 performs a selection process according to the instruction.

That is, when there is an input from the cursor key 12d, if the CPU 10 is in a state of displaying a list of homologous elements (if the group designation mode is set in the designation mode register 22e), the CPU 10 is designated. Perform processing according to the direction.

When the vertical direction is designated in the family designation mode, the CPU 10 determines that the operation is for selecting an element symbol from the family list display, and moves the cursor of the family element list according to the designated direction.

The cursor is moved to an arbitrary element symbol and
When the confirmation is instructed by the confirmation key 12g, the CPU 10
Is the character (element symbol) at the cursor position in the family list display
Is determined and displayed at the original character input position.

When the left / right direction is designated in the family designation mode, the CPU 10 displays the contents of the family list display.
As an operation for changing to the contents of another family, the display is switched to the display of the family list of the family in the designated direction. That is, when the right or left direction is designated, the CPU 10 refers to the periodic table management table 24a based on the element symbol where the cursor currently displaying the family list is located, and determines the peripheral element address corresponding to the corresponding element. Then, the address of the element located on the right or left according to the designation is obtained. And C
The PU 10 obtains a homologous element address corresponding to the element indicated by the right or left address in the peripheral element address, and displays a specified right or left homologous element list.

FIG. 9D shows a display example of the homologous element list when the designation with the right cursor is input while the homologous element list is displayed as shown in FIG. 9C. In this case, the CPU 10 obtains the element “Mg” from the peripheral element address “12” located to the right of the element symbol “Na”, and obtains the cognate element address “4, 20, 38, 56, A list of homologous elements is displayed based on “88” (and “12”).

In this way, a list of the same-period elements or a list of the same-group elements is displayed in response to the instruction of the period designation key 12h or the group designation key 12i with respect to the inputted element symbol, and further, by operating the cursor key 12d. An instruction of the direction can be given arbitrarily, and an element symbol to be input and displayed can be selected from the list. In addition, elements of the same period or elements of the same family are often treated in association with each other because they have similar properties. Display can be used.

In the above description with reference to FIG. 9, an example is described in which the entered element symbol is in the determined state, but the period designation is performed based on the undetermined element symbol. The processing in the mode and the family designation mode may be performed.

Further, based on the entered element symbols,
Regarding the display of the surrounding element symbols in the upper, lower, left and right, the period designation mode and the group designation mode, the related element symbols are displayed separately from the already entered element symbols. May be directly changed to a related element symbol based on the arrangement of the periodic table registered in the periodic table management table 24a in accordance with the designation of the direction by the cursor key 12d.

For example, as shown in FIG. 10, an arbitrary direction, up, down, left and right, is designated to the already entered element symbol "Na" by the cursor key 12d, so that the element symbol in the designated direction is used. To change the entered element symbol.

The method described in the above-described embodiment includes, as programs that can be executed by a computer, for example, a magnetic disk (floppy disk, hard disk, etc.), an optical disk (CD-ROM,
It is also possible to write the data on a recording medium such as a DVD or a semiconductor memory and apply it to various devices, or to transmit it via a communication medium and apply it to various devices. A computer that realizes the present apparatus reads the program recorded on the recording medium, and executes the above-described processing by controlling the operation of the program.

[0086]

As described above in detail, according to the present invention, by inputting an element symbol representing an element, the correspondence between the element and the other element based on the arrangement in the periodic table of the element corresponding to the element is determined. Since the element symbol of another element can be displayed on the basis of this, input of characters representing the element symbol can be simplified.
