3,5} and "B = 4 {2,5,8,11}" are displayed on the display unit 6 via the display drive circuit 7.

Next, as shown in FIG. 8B, on the set calculation input screen on which the elements of each set A and B and the number of elements are displayed, the CPU 2 sets the set processing flag memory 803 in the RAM 8. It is determined whether or not the aggregation processing flag F is "1" with reference to the aggregation processing flag F set in (step S319 in FIG. 7). When the CPU 2 determines that the set processing flag F is “1” (Step S319 in FIG. 7; Yes), the set calculation processing is started.

FIG. 9 is a flowchart showing the flow of the set calculation process. In the set calculation process, the CPU 2
First, it is confirmed whether or not the data input key 3a of the input unit 3 has been operated (step S401). And data input key 3a
Is operated (step S401; Yes), it is determined whether or not the input data is set expression data including set symbols such as "A∩B" and "A∪B" (step S401). S403). Here, the set symbol is a symbol used in a set operation such as a symbol “∩” indicating a common set and a symbol “∪” indicating a union.

For example, when an arbitrary set expression relating to sets A and B is input as “A∩B” (step S40)
2), the CPU 2 determines that "set symbol exists" when the set symbol "A $" is input (step S403; Y).
es), when "A @ B" is subsequently input, a set relation such as a common set of "A" and "B" is determined (step S404; Yes), and the set relation data is determined. Set relation data memory 812 in RAM 8
To memorize.

Next, the CPU 2 determines whether or not a set list relating to sets A and B has been set (step S405). If it is determined that a set list has been set (step S405; Yes), the CPU 2 The number of elements of each set A, B, etc. stored in the list data memory 806 is read, and the size of the circle indicating the set is determined according to the ratio of the number of elements “4: 4” (step S406). In this case, since the ratio of the number of elements is "4: 4", a circle figure of a set having the same diameter is read from the basic set diagram ROM 9a (step S407), and the set relation data memory 812 is set.
Is displayed in a window on the display unit 6 via the display drive circuit 7 based on the set relation data stored in the display drive circuit 7 (see FIG. 8B) corresponding to the input expression “A「 B ”. Step S408).

Here, as shown in FIG. 8B, the “=” key 3 f of the input unit 3 is operated (step S 409;
Yes), the CPU 2 executes the set calculation corresponding to the input set expression “A∩B” to execute the set calculation “A∩B”.
The set list corresponding to "B" is searched in the list data memory 806 (step S410), whether the set expression includes a set symbol (step S411), and whether the set list corresponding to sets A and B exists. (Step S
412) is determined.

The set expression has a set symbol (step S4).
11; Yes), when there is a set list corresponding to the set lists A and B (step S412; Yes), first,
The CPU 2 determines whether the set symbol is “∩” indicating a common set (step S413). If the set symbol is “$” indicating a common set (step S413; Y
es), searching the corresponding set lists A and B for elements {2, 5} common to the respective sets,
The data memory 81 of the RAM 8 together with the number of elements “2”
0 is stored (step S414).

Then, the CPU 2 searches for the elements of the common set of the sets A and B, sorts the stored {2, 5} according to the numerical values (step S415), and sets the set in the list data memory 806. For the list (sheet number “1”), the elements {2, 5} and the number of elements “2” are additionally stored in association with the set expression “A $ B” (step S419), and “ 2 {2, 5} "is displayed on the display unit 6 (step S420).

On the other hand, in the determination of the set symbol in step S413, if the set symbol is not “∩” indicating a common set (step S413; No), it is further determined whether or not the set symbol is “∪” indicating a union set. Is determined (Step S41)
6). For example, when the expression is input as “A∪B” (step S416; Yes), the CPU 2 selects all the elements “A” and “B” of the sets A and B from the corresponding set list stored in the list data memory 806. A = ｛1,2,3
5} "and" B = {2,5,8,11} ", and one of the common elements is deleted, and the set A,
The element “{1, 2, 3, 5, 8, 11}” of the union of B and the number of elements “6” are stored in the 格納 data memory 811 (step S417).

Then, the CPU 2 retrieves and stores {elements} 1,2,3,5,5 as elements of the union of sets A and B
8, 11} are aligned according to the numerical values (step S41).
8), with respect to the set list (sheet number “1”) set in the list data memory 806, the elements {1, 2, 3, 3} corresponding to the set expression “A∪B”
5, 8, 11} and the number of elements "6" are additionally stored (step S419). Then, the display unit 6 displays "6-1, 2, 3, 5, 8, 11} through the display drive circuit 7 (step S420).

Next, the elements of the set have not been entered in the set list, and the set expression "A $" is displayed on the set calculation input screen G2.
An example of the set calculation process when only "B" is input will be described in detail with reference to FIGS. FIG. 10 is a diagram showing a display example in the set calculation processing when no element is input to the set list. FIG. 10A shows the set expression “A∩B” on the set calculation input screen G2 in this case. FIG. 10B is a diagram displaying a set relation diagram G3 of the set expression “A∩B”.

Set calculation processing (set processing flag F =
When shifting to “1”), if there is no set list setting operation for the list data memory 806 and no sheet number is set in the selection list data memory 807,
Set calculation input screen G by operating "EXIT" key 3d
2 is displayed on the display unit 6 (step S3 in FIG. 7).
12 to step S316), as shown in FIG. 10A, by operating the data input key 3a of the input unit 3 (step S401), for example, when the set expression “A∩B” is input (step S402), the CPU 2 When the set symbol "A $" is input, it is determined that there is a set symbol (step S4).
03; Yes), and subsequently, when "A @ B" is input, the set relationship between the common set of "A" and "B" is determined (step S404; Yes), and the set The relation data is stored in a set relation data memory 812 in the RAM 8.

Then, the CPU 2 determines whether or not the set of the set list has been set (step S405). In this case, it is determined that the set list is not set (step S405; N
o), based on the set relation data stored in the set relation data memory 812, the CPU 2
9a, a basic set figure indicating a common set of the two sets A and B is read out (step S407), and a set relation diagram G3 corresponding to the set expression “A∩B” as shown in FIG.
Is displayed on the display unit 6 (step S408).

Here, when the “=” key 3 f of the input unit 3 is operated (step S 409; Yes), the CPU 2
A set list corresponding to the input expression “A∩B” is searched (step S410). However, in step S412, it is determined whether there is a corresponding set list (step S41).
2) In this example, it is determined that there is no corresponding set list (Step S412; No). Further, the CPU 2 determines whether or not the set expression has an expandable configuration (step S421). Here, the expansion of the set expression means that the set expression is transformed and expressed by using the set exchange law, the association law, and the distribution law. For example, an expression in which “A∩ (B∪C)” is input By using the distribution rule of the set expression as “(A∩B) ∪
(A∩C) ”. In the expansion of this set expression, an element number arithmetic expression in the calculation of the number of elements of the set, for example, n (A∪B) = n (A) + n (B) −n
Expression transformations such as (A∩B) are also included.

In the case of this example, the input set expression is “A∩
B ”, it is determined that deployment is not possible (step S4
21; No), the display of the set expression is not changed. If the set expression can be expanded, (Step S421; Ye
s) The expansion formula is displayed (step S422).

Next, a set calculation process executed when a set element is not input to the set list and a set expression other than the above example “A 例 B” is input will be described.

FIG. 11 is a diagram showing a display example of a set diagram corresponding to each set expression input when there is no input of the set list, and FIG. 11A shows a subset expression “N⊆Q”.
And a set relation diagram G3 corresponding to this “N⊆Q”, FIG.

When the set list corresponding to the set expression is not set, the set diagram corresponding to the input set expression is converted to the basic set through the processing of steps S401 to S405, step S407, and step S408 as described above. It is read from the figure ROM 9a and displayed on the display unit 6.

Further, the set diagram display control device 1 calculates and displays the number of elements corresponding to the input set expression, and displays the set diagram. FIG. 12 is a diagram illustrating a calculation display state of the number of elements of a set in the set calculation processing.

In the set calculation processing (set processing flag F = 1), the sheet number "1" is set as the corresponding set list in the selection list data memory 807 in the RAM 8, and FIG. As shown in (4), for example, the number-of-elements operation expression “n (A∪B)” is input by operating the data input key 3a of the input unit 3 (step S402).
The CPU 2 determines that there is a set symbol at the time when the set symbol “n (A「) ”is input (Step S403; Yes), and then at the time when“ n (A∪B) ”is input. A set relationship between the union of "A" and "B" is determined (step S404), and the set relationship data is stored in the RAM.
8 is stored in the set relation data memory 812.

The CPU 2 determines whether or not a set list relating to sets A and B has been input and a corresponding set list has been set (step S405). If it is determined that a set list has been set (step S405; Yes) ),
The size of the circle indicating the set is determined according to the ratio "4: 4" of the number of elements of each set A and B (step S406). In this case, the ratio of the number of elements is "4: 4". A circular figure of a set having the same diameter is read from the basic set diagram stored in the ROM 9 (step S407), and the set relation data memory 8 is read.
Based on the set relation data stored in step S12, the set relation diagram corresponding to the input expression “n (A∪B)” is displayed on the display unit 6 via the display drive circuit 7 (step S40).
8).

Here, in order to execute the calculation of the number of elements corresponding to the inputted number-of-elements arithmetic expression "n (A∪B)", the CPU 2 performs the input operation as shown in FIG. 3 is operated (step S409; Ye).
s) and a set list corresponding to the element number arithmetic expression is searched (step S410), and whether or not there is a set symbol “∪” (step S411), whether there is a set list corresponding to sets A and B It is determined whether or not (step S412).

When the corresponding set list is set (step S412; Yes), the CPU 2 determines that the input expression “n (A∪B)” is an element number operation expression (step S416). No, step S42
3; Yes), set A {1, 2, 3, 5} and set B
The number of elements “6” of the union with {2, 5, 8, 11} is calculated (step S424), and the calculation result is expressed as “6 ｛1,
2, 3, 5, 8, 11} "is displayed on the display unit 6 as shown in FIG. 12B (step S420).

On the other hand, as shown in FIG. 12C, the operation of the “=” key 3 f of the input unit 3 (step S 409) corresponds to the expression “n (A∪B)” input by the CPU 2. The set list is searched (step S410),
When it is determined that the list of the corresponding sets A and B does not exist (step S412; No), the input expression “n”
(A∪B) ”can be expanded (step S42).
1; Yes), “n (A) + n (B) −n (A∩B)”
Is developed and displayed (step S42).
2).

When the CPU 2 determines that a set symbol does not exist in the input set expression in accordance with the operation of the "=" key 3f of the input unit 3 (step S409) (step S4).
11; No), it is determined as a normal calculation formula, a calculation process is executed (step S425), and the calculation result is displayed (step S426).

Next, the flow of the set diagram calculation process executed when the "set diagram calculation mode" is selected and set by the set mode selection will be described in detail with reference to FIGS.

First, the set mode is selected on the mode selection screen G (see FIG. 6A), and the icon of the “set view” of the tablet 4 is displayed on the set processing menu screen G1 (see FIG. 6B). When the group diagram calculation mode is selected by a touch operation, the CPU 2 sets the group processing flag F to “2”.

FIG. 13 is a flow chart showing the flow of the group diagram calculation process executed by the group diagram display control device 1.
FIG. 14 is a diagram illustrating a calculation display state (part 1) of the set diagram G4 and the set relation list G5 accompanying the set diagram calculation processing of the set diagram display control device 1, and FIG. It is a figure which shows the calculation display state (No. 2) of the set diagram G4 and the set relation list G5 accompanying the set diagram calculation process.

First, when the process is shifted to the set diagram calculation process, if the sheet number of the set list is not selected and set in the selection list data memory 807, the "EXI"
When the "T" key 3d is operated (step S31 in FIG. 7).
2; Yes), the CPU 2 determines whether or not the list display flag N in the list display flag memory 804 in the RAM 8 is "1" (step S31 in FIG. 7).
3) If the list display flag N is "1",
It is reset to "0" (step S314 in FIG. 7), the list input screen displayed on the display unit 6 is closed, and the group diagram calculation input screen is displayed (step S314 in FIG. 7).
315).

Here, the set diagram calculation input screen is a set diagram display in which a set diagram is displayed based on the information input to the set relationship list G5 for inputting information about the set and the set relationship list G5. This is a screen having a range G4, and a set relation list G5 includes symbols (A,
B,...) And their set expressions (A∩
B, A∪B,...) Are arranged, and it is possible to input an element or the number of elements to each of the input fields via the input unit 3 (see FIG. 14). It is assumed that no set diagram is displayed on the initial screen where no data is input to the set relation list G5.

The CPU 2 has a selection list data memory 80
In 7, it is determined whether or not the set list is selected and set (step S316 in FIG. 7). Then, in this case, if it is determined that the set list is not set (Step S316 in FIG. 7; No), then the set processing flag memory 80
When it is determined that the set processing flag F of No. 3 is “2” (Step S319 in FIG. 7; No), the processing shifts to the set diagram calculation processing shown in FIG.

In the set diagram calculation process shown in FIG. 13, first, the CPU 2 determines whether or not a set diagram indicating the relationship between the sets arranged in the set relationship list G5 is displayed on the display unit 6 (step S501). . Here, the display unit 6 displays only a set relation list G5 composed of a predetermined set of symbols and an array of set expressions, and if it is determined that a set diagram is not displayed (step S501; No), furthermore, C
PU2 determines whether a set list is set or not (step S502). If it is determined that no element or the like has been input to the set list and the set list has not been set (step S502; No), a basic set diagram corresponding to the sets arranged in the set relation list G5 is created. The basic set diagram including sets A, B, C, and D is read from the set diagram ROM 9a and displayed on the display unit 6 (step S503), and the basic set image is displayed in the basic set diagram flag T of the basic set diagram display flag memory 805. "1" indicating that the operation has been performed is set (step S504).

Returning to the processing of step S501 again, the CP
U2 determines whether or not to display a set diagram. If the CPU 2 determines that “1” is set in the basic set diagram display flag T of the basic set diagram display flag memory 805 (step S505; Yes), then the symbols (A, B) of each set in the set relation list G5 ,... Are monitored (step S506), and when the number of elements or elements of each set is input by operating the data input key 3a (step S507), the rectangular diagram in the set diagram or The encircling area generated by the circle diagram is deformed and displayed in a size corresponding to the number of elements (step S508).

Here, the CPU 2 operates the “=” key 3 of the input unit 3.
After confirming that the operation of f has been performed (step S509;
Yes), based on the number of elements of each set arbitrarily input on the set relation list G5 and the elements, each element corresponding to every set relation obtained by combining each set and the number of elements are calculated (step S510), and the operation is performed. Data memory 80
9 (step S511), and additionally displayed as corresponding data of each set expression in the set relation list G5 (step S512).

In this case, the contents of the elements calculated and displayed corresponding to each set expression on the set relation list G5 are displayed up to a predetermined number of elements which can be displayed on the display area of the set relation list G5. The display of elements that cannot be displayed thereafter is omitted (step S513).

On the other hand, when the process is shifted to the set diagram calculation process, while the set list (sheet number) is selected and set in the selection list data memory 807, the input unit 3 sets the "E"
When the "XIT" key 3d is operated (step S3 in FIG. 7)
12; Yes), the CPU 2 determines whether or not the list display flag N in the list display flag memory 804 in the RAM 8 is "1" (step S31 in FIG. 7).
3) If the list display flag N is "1",
It is reset to "0" (step S314 in FIG. 7), the list input screen displayed on the display unit 6 is closed, and the group diagram calculation input screen is displayed (step S31 in FIG. 7).
5).

The set diagram calculation input screen in this case is the symbol (A) of each set stored in the set list in the list data memory 806 corresponding to the sheet number set and stored in the selection list data memory 807. , B,...) And a predetermined set expression (A∩B, A∪B,...) Such as a common set or a union composed of a predetermined combination thereof are arranged on the display unit 6 as a set relation list G5. FIG. 14 is a screen for displaying a set diagram showing the relation of the sets arranged in the set relation list G5 (see FIG. 14).

Then, the CPU 2 determines whether or not a set list is selected and set in the selection list data memory 807 (step S316 in FIG. 7). If it is determined that there is a set in the set list (step S3 in FIG. 7)
16; Yes), the CPU 2 sets the symbols (A, B,...) Of each set in the set relation list G5 displayed on the display unit 6.
The number of elements of each set stored in the set set list is displayed in association with the set (step S31 in FIG. 7).
At the same time, the content of the element is displayed in a displayable predetermined number (step S318 in FIG. 7).

For example, the list data memory 8 corresponding to the sheet number set in the selection list data memory 807
In the set list in 06, the elements and the number of elements are stored in advance for the three sets A, B, and D.
The elements of the sets A and B are partially common, and the elements of the sets A and B are all included in the elements of the set D (see FIG. 1).
4) will be described.

In this case, in the set diagram calculation process in FIG. 13, first, the CPU 2 determines whether or not a set diagram corresponding to the set relation list G5 is displayed on the display unit 6 (step S501). Here, the display unit 6 displays only the set relation list G5 including an array of set symbols and set expressions, and determines that the set diagram is not displayed (step S501; No). Then, it is determined whether or not the set list has been set (step S502). If it is determined that the set list is set (step S502; Yes), the elements of each set A, B, and D in the set set list are compared (step S502).
514) First, it is determined whether or not there is a set including all the elements of another set (step S515). That is, in this example, it is determined that there is a set D including all the elements of the sets A and B (step S515; Yes), and the set D is stored in the set relation data memory 812 as an entire set (step S516).

Subsequently, the CPU 2 repeatedly compares the elements among the sets A, B, and D (step S514), and determines whether or not there is a set including all the elements of another set (step S515). If it is determined that there is no set including all the elements of the other set (step S515; No), then the CP
U2 determines whether there is a set having a partially common element (step S517). That is, in this example, it is determined that the set A and the set B have some common elements, the sets A and B are set as a common set (step S518), and stored in the set relation data memory 812.

Further, when it is determined that there is no set having some common elements (step S517), it is determined that there is no set having some common elements (step S517;
No), set as a single set (step S519),
It is stored in the set relation data memory 812.

When the analysis of each set relation with respect to the set set list is completed (step S520; Ye)
s), the CPU 2 draws a set diagram based on the data indicating the relation between the sets stored in the set relation data memory 812.

That is, as shown in FIG.
2 displays a rectangular diagram of the entire set together with the symbol D (step S521), and then displays the set B of the maximum number of elements included in the entire set D together with the symbol B as a circle diagram with a predetermined radius r ( Step S522).

Then, the CPU 2 reduces the circle diagram of the set B having the radius r by the ratio of the circle diagram of the set A to the number of elements of the set B according to the number of elements included in the set A, and It is displayed as a set (step S523).

When the drawing of the set diagram corresponding to the set set list is completed (step S5).
24), elements included only in the entire set D are detected (step S525), and the set C is stored in the corresponding set list in the list data memory 806 together with the number of elements (step S526). The number of elements and the contents of the elements are additionally displayed in the set relation list G5 within a displayable range (step S527, step S528).

Thereafter, in the set diagram calculation processing, FIG.
As shown in (B), the CPU 2 executes step S501.
In step S501, it is determined that the set diagram is displayed (step S501; Yes). When the operation of the “=” key 3f of the input unit 3 is detected (step S509; Yes), the corresponding list in the list data memory 806 is displayed. Based on the elements of each set list A, B, C, D stored in the set list, all other set relations (A∩B, A∩C, A∪B,...)
.) Are calculated (step S510), and additionally stored in the set list (step S511), and additionally displayed in the set relation list G5 within a displayable range (step S512, step S512).
513).

For example, the selection list data memory 8
In the set list in the list data memory 806 corresponding to the list number set to 07, three sets A,
Each element of B and C is “A: {1, 2, 3, 5}, B:
{2,5,8,11}, C: {1,2,3,4,5,
6, 7, 8, 11} ", where the elements of the sets A and B are partially common, and the elements of the sets A and B are all included in the elements of the set C. (See FIG. 15) will be described.

In this case, the CPU 2 first determines that the set diagram is not displayed in the set diagram calculation processing in FIG. 13 in the determination of whether or not the set diagram is displayed (step S501; No). When it is determined that there is a set list in the determination of whether or not there is a setting (step S502; Yes), the elements between the sets A, B, and C in the set set list are compared (step S51).
4) First, a set containing elements of another set, that is,
It is determined that there is a set C including all the elements {1, 2, 3, 5, 8, 11} of the sets A and B (step S515; Ye)
s), this set C is set to all sets (step S51)
6) Store in the set relation data memory 812.

Subsequently, the comparison between each set element is repeated (step S514), and the set having some common elements
That is, when it is determined that the sets A and B are common to the elements {2, 5} (step S517; Yes), the sets A and B are set as a common set (step S518),
It is stored in the set relation data memory 812.

Further, when there is another single set (step S517; No), the corresponding set is set as a single set (step S519) and stored in the set relation data memory 812.

When the analysis of each set relation with respect to the set set list is completed (step S520).
Yes), the CPU 2 executes the set relation data memory 812
A set diagram is drawn and displayed based on the data indicating the relationship between the sets stored in. First, as shown in FIG. 15A, a rectangular diagram of the entire set C is displayed together with the symbol C (step S521), and then the set A or B having the maximum number of elements “4” included in the entire set C is displayed. A circle diagram with a radius r set in advance is displayed together with the symbol A or B (step S52).
2).

Here, if the circle diagram of the set A is displayed first, the CPU 2 then converts the circle diagram of the set B into the set A according to the number of elements “4” included in the set B. Is displayed as a common set as a circle diagram of the same diameter r as the circle diagram of the set A having the radius r by the ratio with the number of elements “4” of the step S5.
23).

When the drawing of the set diagram corresponding to the set set list is completed (step S524; Y
es), the CPU 2 detects the elements {4, 6, 7} included only in the entire set C (step S525), and as the set D, together with the number of elements “3”, the list data memory 8

8).

Thereafter, in the set diagram calculation processing in FIG. 13, the CPU 2 determines that the set diagram is displayed (step S501; Yes), so that the “=” key of the input unit 3 as shown in FIG. 3f is operated (step S5).
09; Yes), based on the element data of each set A, B, C, D set in the corresponding set list in the list data memory 806, all other set relationships (A∩B,
(A∩C, A∪B,...) Are calculated (step S510), and the calculation result is additionally stored in the set list (step S51).
1) Additional display is performed within a range that can be displayed as the set relation list G5 (step S512, step S513).

As described above, in the set calculation process executed by the set diagram display control device 1 in the first embodiment, when an arbitrary set expression “A∩B” is input, the CPU 2 Is displayed on the display unit 6, and a diagram showing the relation of the sets corresponding to the input set expression is displayed.

The set diagram displayed in the set diagram calculation process according to the first embodiment is a process in which the size of the circle diagram is determined based on the ratio of the number of elements of each set, and each set is displayed. In contrast, the group diagram display control device 1 according to the second embodiment performs a group diagram display process described later (see FIG. 17).

That is, in the set diagram display processing (see FIG. 17) described later, when the elements or the number of elements of each set are input to the set relation list G5, the CPU 2 responds to these elements or the number of elements. Calculate the number of elements in all the relations of the set that can be calculated, determine the display range of the set diagram according to the input or calculated number of elements, and further configure the circle diagram within the display range. And the display position and size of the rectangular diagram are determined, and the set diagram is displayed at the determined display position and size.

FIG. 16 is a diagram showing the configuration of the RAM 8 of the collective diagram display control device 1 according to the second embodiment. RAM of collective diagram display control device 1 according to second embodiment
Reference numeral 8 further includes an element number data memory 816 in addition to the configuration of the RAM 8 shown in the first embodiment. The number-of-elements data memory 816 stores the number of elements of sets or relationships between sets (eg, common set, union, complement, subset).

Next, the operation will be described. FIG. 17 is a flowchart showing the flow of a group diagram display process executed by the group diagram display control device 1. FIG. 18 is a display example of a group diagram, a group formula, a solution thereof, and the like displayed by the group diagram display process. FIG.

First, the CPU 2 executes the entire processing shown in FIG.
When the set diagram calculation mode is selected and set by the set mode setting in the set mode process shown in FIG. 5, the set diagram calculation input screen stored in the ROM 9 is read out and displayed on the display unit 6 (step S601; FIG. 18 (A)). This set diagram calculation input screen is a rectangular diagram c showing the entire set.
4 and circle diagram c1 showing set A therein, c showing set B
2, a circle diagram c3 indicating the set C is displayed as a set diagram in the set diagram display range G4, and each set A, B,
A set relation list G5 for inputting information about C,... Is displayed.

For this set relation list G5, the number of elements of all sets, the number of elements of each set (A, B, C...), The common set (A∩B, B∩C,. Set (A∪B, B∪
The number of elements such as C,...
a (step S602), and when an operation execution instruction is input by operating the "execute" key 3c of the input unit 3 (step S603), the CPU 2 determines the set relation from the number of elements of the input set. Is calculated (step S604).

That is, when there is no element input to the set list and only the number of elements of each set is input to the set relation list G5 as in this example, for example, the set A And the number of elements of the complement of set B and set C, or the intersection of set A, set B and set C (A {B}
The number of elements of any set relation such as C) is calculated. In addition,
At the time of inputting the number of elements (step S602), a list input screen (see FIG. 3) may be displayed, and the elements of each set may be input to each set list. When an element is input to the set list, the CPU 2 calculates the number of elements of each set based on the elements input to the set list, and further calculates the number of elements such as a common set, a union set, and a complement set. I do.

The CPU 2 stores the calculated number of elements of each set in the number-of-elements data memory 816 in the RAM 8 in association with the set expression indicating the set relation.

Next, the CPU 2 determines the display range of the set diagram. Since the initial set diagram of the set diagram calculation input screen displayed on the display unit 6 is a basic set diagram that does not correspond to the number of elements of the input set, a rectangular diagram c4 indicating the entire set is displayed on the display screen. The group diagram display range G4 is determined so as to fall within the range (step S605).

That is, the product of the maximum value X in the horizontal direction and the maximum value Y in the vertical direction of the rectangular diagram c4 showing the entire set is determined to be approximately the number of elements of the entire set. For example, when the number of elements in the entire set is 50, the maximum value X in the horizontal direction is determined to be 10 and the maximum value Y in the vertical direction is determined to be 5.

Further, the CPU 2 changes the group diagram display range G4 to 0 ≦ x ≦ X + α in the horizontal direction and 0 ≦ y ≦ Y + β in the vertical direction (step S606). Here, α and β are values indicating the margin of the set diagram display range G4. When the group diagram display range G4 is changed in this way, a rectangular diagram c4 showing the entire group
Is always displayed in the group diagram display range G4 in the display screen (see FIG. 18C).

Further, the CPU 2 determines the radius of the circle diagram c1 representing the set A so that the area of the circle diagram c1 representing the set A is equal to the number of elements of the set A (step S607). The radius of the circle diagram c2 indicating the set B is determined so that the area of c2 matches the number of elements of the set B (step S6).
08). Then, a common set of set A and set B (A∩B)
The center coordinates of the circle chart c1 indicating the set A and the circle coordinate c2 indicating the set B are set such that the area of the circles coincides with the number of elements of the common set (A） B) of the set A and the set B input or calculated. Each is determined (step S609).

Thereafter, the CPU 2 checks whether or not information such as the number of elements of another set (set C) has been input to the set relation list G5 or each set list on the list input screen (step S610). If the number of elements is input for the set C, the radius of the circle c3 indicating the set C is changed so that the area of the circle c3 indicating the set C matches the number of elements of the set C. Decide (Step S
611), a set such that the area of the common set (A∩C) between the set C and the set A and the common set (B∩C) between the set C and the set B match the input or calculated number of elements. The center coordinates of the circle diagram c3 indicating C are determined (step S61).
2).

Thereafter, if there is no other set, the CPU 2 sets the circles c1 and c1 showing the sets A, B and C, respectively.
c2 and c3 are displayed on the display unit 6 with the obtained radius and center coordinates (step S613).

FIG. 18 is a diagram showing a display example of a set diagram, set expressions, their solutions, and the like displayed by the set diagram display processing. FIG. 18A is read out from the basic set diagram ROM 9a and displayed. Display example of a set diagram calculation input screen on which the displayed basic set diagram and set relation list G5 are displayed, FIG.
18B shows an example in which the number of elements is input to the set relation list G5. FIG. 18C shows the size of a rectangular diagram c4 indicating the entire set according to the number of elements in the set diagram display processing. It is a figure which shows the example in which the radius and center position of the circle diagrams c1, c2, and c3 showing A, B, and C were changed and displayed.

When the set diagram calculation mode is set, FIG.
As shown in FIG. 3A, the CPU 2 reads out and displays the set diagram calculation input screen stored in the ROM 9. This set diagram calculation input screen is a set diagram display range G for displaying the set diagram.
4 and a set relation list G5 are displayed. Circle diagrams c1 to c3 in which a part of three circles having the same radius are overlapped as a set diagram and a rectangular diagram c4 surrounding the three circles are read from the basic set diagram ROM 9a and displayed, and a set relation list G5 is a field for inputting the number of elements of a set corresponding to each of the circle diagrams c1 to c3 and the rectangle diagram c4, "A:",
"B:", "C:", "D:", "A 、 B:
, "B @ C:", "A @ C:" are displayed.

The number of elements of each set is input to the set relation list G5. For example, as shown in FIG. 18B, “A: 45”, “B: 22”, “C: 7”, “D: 5”
0 ”,“ A∩B: 7 ”,“ B∩C: 14 ”,“ A∩C:
When "1" is input, the CPU 2 determines the maximum value X in the horizontal direction and the maximum value Y in the vertical direction of the set diagram display range G4 from the number of elements of the entire set D. That is, for example, the maximum value X in the horizontal direction is set to 7 so that the product of the maximum value X in the horizontal direction and the maximum value Y in the vertical direction becomes substantially equal to 50 which is the number of elements of the set.
And the maximum value Y in the vertical direction is 7. The determined maximum value X in the horizontal direction and the maximum value Y in the vertical direction are respectively defined as the lengths in the horizontal direction and the vertical direction of the rectangular diagram showing the entire set. Further, the radius of the circle indicating the set A is determined so that the area of the circle indicating the set A is approximately "45", and the radius is set to approximately "3.8". Further, similarly, the radii are determined for the sets B and C, and the radii are respectively set to “2.
6 "and" 1.5 ".

Then, a common set “A∩B” of each set,
The area of “B∩C” and “A 面積 C” is “7”,
The center coordinates of each circle are determined so that the circles c1 to c3 indicating "3" and "1" and indicating the sets A, B and C fall within the rectangular diagram c4 indicating the entire set. At the radius of the circle indicating each set determined in this way and the center coordinates, each circle diagram c1 to c1
c3 and the rectangular diagram c4 are displayed as shown in FIG.

As described above, in the second embodiment, the set diagram display control device 1 executes the set diagram display process to determine whether the elements or the number of elements of each set are in the set relation list G5. When input, the number of elements in all relations of the set is determined according to this element or the number of elements, and the display range of the set diagram is determined according to the input or calculated number of elements. The display positions and sizes of the circle diagrams c1 to c3 and the rectangular diagram c4 constituting the set diagram are determined in the diagram display range G4, and the set diagram is displayed at the determined display positions and sizes.

Therefore, since the display range is determined according to the number of elements, the set diagram can be displayed in an appropriate size within the set diagram display range G4 regardless of the number of elements. Can be easily seen. Also, even when a group diagram is displayed on a relatively small scientific calculator or the like on the display screen, the group diagram can be displayed flexibly in accordance with the number of input elements.

Further, since the display position and size of the circle in the set diagram are determined according to the number of elements in the set, a circle having a size corresponding to the number of elements can be displayed, and when the size is changed, Since the common set is always secured with the size corresponding to the number of elements, the relation of each set can be displayed correctly, and the relation of the set can be grasped as an image. Can be improved.

FIG. 19 is a diagram showing the configuration of the RAM 8 of the collective diagram display control device 1 according to the third embodiment.
R of the group diagram display control device 1 in the third embodiment.
The AM 8 further includes an element number data memory 816 and an area data memory 817 in addition to the configuration of the RAM 8 in the first embodiment.

The number-of-elements data memory 816 stores the number of elements of sets or relationships between sets (common set, union, complement, subset, etc.) (see FIG. 22B).

The area data memory 817 stores the range of each enclosing area in the set diagram in association with the set relation (see FIG. 22A).

That is, in a tracing process described later (see FIG. 20), the CPU 2 sets the group diagram calculation input screen (FIG. 2).
1), circle diagrams c1 to c3 of the basic set diagram are displayed.
The area data memory 81 of the RAM 8 associates each of the surrounding areas e1 to e8 generated by the
7 temporarily. When inputting the number of elements of each set to the set relation list G5, the CPU 2 identifies and displays the input field specified by operating the cursor key 3g of the input unit 3, and sets the set relation of the specified input field. The corresponding surrounding area is read out from the area data memory 817 in the RAM 8, and the surrounding area is identified and displayed.

Further, the CPU 2 executes the set chart display processing shown in the second embodiment, and thereby sets each of the surrounding areas e1 to e8 generated by the circle charts c1 to c3 and the rectangle chart c4 indicating each set. The area data newly stored in the area data memory 817 in the RAM 8 in association with the set relation, and when an arbitrary set expression is input from the input unit 3, the enclosing area corresponding to the set expression is newly stored in the RAM 8 Memory 8
17, the acquired area is identified and displayed in a different color or display pattern from the other parts.

Next, the operation will be described. FIG. 20 is a flowchart showing the flow of the trace processing executed by the group diagram display control device 1. Here, the trace refers to any of the enclosed areas e1 to e8 of the displayed set diagram, or any set expression or the like arranged in the set relation list G5, using the cursor key 3 of the input unit 3.
It means to specify by the operation of g.

First, when the set mode is set on the mode selection screen G (see FIG. 6A) and the set diagram calculation mode is selected and set on the set processing menu screen G1 (see FIG. 6B), the CPU 2 Reads the group diagram calculation input screen stored in the ROM 9 and displays it on the display unit 6 via the display drive circuit 7 (step S701;
See FIG. 21). The CPU 2 displays a circle diagram c of the displayed set diagram.
1 to c3 and the surrounding areas e1 generated by the rectangular diagram c4.
e8 is analyzed, and the surrounding areas e1 to e8 are associated with the set relation and stored in the area data memory 817 in the RAM 8 (step S702).

That is, as shown in FIG. 21, the set diagram displayed on the set diagram calculation input screen is changed to the set A, B, and C, for example.
Assuming that the relationship between one set and all sets D is shown, each circle diagram c1 showing three sets A, B, and C in the full set D
Each of the surrounding areas divided by the arcs of c2 and c3 is denoted by e1 to e.
8 and the range of each enclosed area is associated with the set
It is stored in the area data memory 817 of M8. For example, the area e1 is stored in association with the set relation shown in Expression 1.

[0167]

(Equation 1)

Subsequently, when the CPU 2 detects an operation of the cursor key 3g of the input unit 3 (step S703), the set relation list G5 specified by the cursor key 3g.
Is changed and displayed (step S704; see FIG. 23A). Then, the area data corresponding to the set relation of the input fields designated by the cursor moving operation is acquired from the area data memory 817 in the RAM 8, and the color or display pattern of the designated surrounding area is changed and displayed ( Step S70
5; see FIG. 23 (A)).

When the number of elements of the corresponding set is input from the input unit 3 to the input field specified by operating the cursor keys 3g by operating the data input keys 3a (step S706), the CPU 2 proceeds to step S706. The input element number is stored in the element number data memory 816 in the RAM 8 in association with the set expression. Thereafter, the CPU 2 determines whether or not the “execute” key 3c of the input unit 3 has been operated (step S2).
707) If there is no operation (step S708), the process returns to step S703 to identify both the input field specified by the moving operation of the cursor key 3g and the surrounding area corresponding to the specified input field. When the number of elements in the set is displayed by operating the data input keys 3a of the input unit 3 in the designated input field, the input element numbers are sequentially stored in the element number data memory 816.

After that, when the "execute" key 3c of the input unit 3 is operated (step S707; Yes), the CPU 2
The number of elements of the relation (common set, union, complement, etc.) of each set is calculated from the input number of elements, and the number of elements of the relation of each set obtained by the calculation is further stored in the element number data memory 816 of the RAM 8. (Step S708). Thereafter, the CPU 2 obtains the number of elements input or calculated and stored in the number-of-elements data memory 816, and calculates the position and size of the set diagram from the number of elements (step S70).
9). The process of calculating the position and size of this set diagram is as follows:
This is the same as that performed in the group diagram display process (see FIG. 17) in the second embodiment. That is, the maximum value X in the horizontal direction and the maximum value Y in the vertical direction of the rectangular diagram c4 indicating the entire set are determined from the number of elements of the entire set, and the circle diagrams c1 to c3 indicating the respective sets are determined from the number of elements of each set. The radius is calculated, and the center coordinates of each of the circle diagrams c1 to c3 are calculated from the number of elements of the common set.

The CPU 2 analyzes the range of each of the enclosing areas e1 to e8 generated by the circle diagrams c1 to c3 and the rectangular diagram c4 of the set diagram determined by the calculated center coordinates and radius of the circle, and It is stored in the memory 817 (step S710), and the display of the group diagram is updated (step S711).

Thereafter, when an arbitrary set expression is input to the set expression input field of the set relation list G5 by operating the data input key 3a of the input section 3 (step S712; Ye).
s), the CPU 2 reads the surrounding area corresponding to the input set expression from the area data memory 817 of the RAM 8, and displays the range of the read surrounding area by changing the color or the display pattern (step). S713; FIG.
3 (B)). Thereafter, the CPU 2 reads out the number of elements corresponding to the input set expression from the element number data memory 816 and displays it on the display unit 6 (step S714; FIG. 2).
3 (B)).

When the user operates the cursor key 3g of the input unit 3 to move the cursor up / down / left / right (step S715), the cursor key 3g is operated based on the enclosed area identified and displayed in the set diagram. (Step S716).

For example, in the example shown in FIG. 21, the area e1 is first identified and displayed as a reference surrounding area, and in this state, if a rightward movement is instructed by the cursor key 3g of the input unit 3, the area e1 is displayed to the right of the area e1. The adjacent area e6 is identified and displayed, and when rightward movement is instructed again, the area e3 adjacent to the right is identified and displayed. Further, when the rightward movement is instructed in a state where there is no surrounding area adjacent to the right, the area e1 located at the leftmost end is identified and displayed again. In addition, the areas e1, e
When it is desired to specify the set A occupying the four surrounding areas 4, 4, e7, and e7, it is possible to simultaneously designate a plurality of surrounding areas by simultaneously operating the cursor key 3g of the input unit 3 and another key.

Further, when an arbitrary enclosed area on the set diagram is designated via the tablet 4, when one point on the set diagram is designated by pressing the input pen P, the CPU 2 sets the designated point. The enclosing area including the area is acquired from the area data memory 817, and the acquired range is identified and displayed.

Thereafter, the CPU 2 reads the set expression indicating the designated surrounding area in the set diagram and the number of elements from the area data memory 817 and the number-of-elements data memory 816 by operating the cursor key 3g and the like, and reads the set expression. Is displayed (step S717).

Thereafter, the processing of steps S712 to S717 is repeatedly executed until an end instruction is input from the input unit 3, and when the end instruction is input (step S7).
