(First embodiment)
FIG. 5 is a diagram showing a display operation (part 1) of the first embodiment associated with the graphic display processing of the graph scientific calculator 10. FIG.

  FIG. 6 is a diagram illustrating a display operation (part 2) according to the first embodiment associated with the graphic display process of the graph scientific calculator 10.

  When the graphic display mode is set in response to a user operation and the graphic display processing program 22a is started, a graphic display function menu selection screen is displayed on the color display unit 16, and a standby state for designating a user arbitrary function. become.

  Here, when the figure drawing function is designated, the figure desired by the user is changed to the figure drawing data memory 22c in accordance with the process for designating the type and display color of the figure and the process for designating the position and size of the designated figure. Is displayed on the color display unit 16 as a graphic display screen G (step S1).

  For example, as shown in FIG. 5A, when “straight line” is designated as the figure type and the start point C and end point D of the straight line are designated by the touch operation on the graphic display screen G, the straight line CD is drawn and displayed. Is done.

  When “triangle” is designated as the figure type and three vertices A, B, and E of the triangle are designated, a triangle ABE that connects the three vertices in order is drawn and displayed.

  If the display color is not specified here, the line segment of the figure is displayed in [Black].

  When the graphic / line selection function is designated on the graphic display screen G, a selection mark m is added to the graphic or line selected by the touch operation and displayed.

For example, as shown in FIG. 5A, when the “VARS” (measurement) key is operated in a state where three sides of the triangle ABE are selected and the selection mark m is displayed, the types of measurement related to the triangle ABE. A measurement icon (not shown) indicating [area] [peripheral length] is displayed in the graphic display screen G. Here, when the [Area] measurement icon is selected, the area of the triangle ABE selected by the selection mark m is measured (calculated) and stored in the graphic measurement data memory 22e as [7.0615 units ² ]. At the same time, it is pasted and displayed in the graphic display screen G (step S2).

  Then, by moving the vertex E of the triangle ABE on the straight line CD to perform an animation display for changing the triangle ABE, after selecting the vertex E and the straight line CD according to the user operation, “F6 ”(Animation menu) In accordance with the operation of the key,“ Add Animation ”is selected according to the operation menu displayed along the lower end of the graphic display screen G, and“ F6 ”(animation Menu) Select “Edit Animation” according to the operation menu displayed along the lower end of the graphic display screen G according to the key operation.

  Then, as shown in FIG. 5B, the Edit Animations screen G1 is displayed, and the number of divisions [Steps], the number of repeats [Times], and the number of divisions of the straight line CD for moving the vertex E on the straight line CD are displayed. The user is prompted to enter a start point [t0] and an end point [t1] within the number [Steps].

  In this Edit Animations screen G1, while selecting each item sequentially with the reverse cursor Cu, for example, the number of repeats [Times: 10], the number of divisions [Steps: 20], the movement start point [t0: 0] of the vertex E, the movement end When the point [t1: 1] is input, each input data is stored in the animation setting data memory 22f (step S3).

  The number of divisions [Steps: 20] is setting data for dividing the straight line CD into 19 sections with the tip C as “1” and the end D as “20”, and from the movement start point [t0: 0] to the movement end. A point [t1: 1] indicates the first point (tip C “1”) to the last point (end D “20”) of the divided straight line CD.

  In other words, the animation setting data (22f) in this case transforms the triangle ABE while moving its vertex E equally in 20 steps (including the start point) from the tip C to the end D of the straight line CD. This is setting data for repeating 10 times.

  After the animation setting data (22f) is input in accordance with the Edit Animations screen G1 shown in FIG. 5B, the cursor key [↓] 15 is operated to advance the reverse cursor Cu to the next screen. As shown, a condition screen G2 for setting the measurement data conditions related to the graphic displayed on the graphic display screen G and the display color of the graphic corresponding to the conditions is displayed.

  In this condition screen G2, [∠EAB> 90 or ∠EBA> 90] is input as a condition of measurement data related to the triangle ABE, and [Then ΔABE: Red] [Red] as the display color of the triangle ABE corresponding to the condition. When “Else ΔABE: Green]” is input, each input data is stored in the drawing form condition data memory 22g (step S3).

  Then, when the execution of animation display is instructed by operating the “EXE” (execution) key (step S4 (Yes)), the process proceeds to the animation execution process in FIG. 4, and FIGS. 5 (D) to 6 (H). As shown in FIG. 8, the animation display of the triangle ABE according to the animation setting data (22f) and the drawing form condition data (22g) is executed (step SA).

  That is, when the animation execution process is started, first, the movement target point (vertex) E, movement range (straight line) CD, and animation setting data (22f) of the graphic change selected on the graphic display screen G are selected. Based on the number of divisions [Steps: 20], the movement start point [t0: 0], and the movement end point [t1: 1], each point that moves the movement target point (vertex) E on the movement range (straight line) CD The coordinates of the position are calculated and stored in the animation execution data memory 22h (step A1).

  The number of executions is set to 1 (step A2), and the coordinates of the initial position of the movement target point (vertex) E (here, corresponding to the tip C of the straight line CD) are read from the animation execution data memory 22h (step A3). ).

  Then, the coordinates of each drawing point of the triangle ABE when the vertex E of the triangle ABE is moved to the coordinates of the initial position on the graphic display screen G (the tip C of the straight line CD) are calculated and changed ( Step A4).

Then, the triangle ABE deformed according to the coordinates of each drawing point after the change is drawn with the original color and line type, and the measurement data [area: 7.0615 units ² ] is also recalculated and pasted. (Step A5).

  Then, the measurement data (∠EAB, ∠EBA) of the figure (triangle ABE) set in the drawing form condition data memory 22g is calculated based on the modified drawing data of the current triangle ABE (step A6), it is determined whether or not the setting condition [∠EAB> 90 or ∠EBA> 90] [Then ΔABE: Red] [Else ΔABE: Green] is satisfied (step A7).

  Here, for example, as shown in FIG. 5 (D), when the triangle ABE deformed and displayed on the animation screen G3 is determined as ∠EAB> 90 and the setting condition is satisfied (step A7 (Yes)), The triangle ABE is changed to [Red] and displayed in accordance with the display color [Then ΔABE: Red] corresponding to the condition [∠EAB> 90] (step A8).

  At this time, if the measurement data [∠EAB, ∠EBA] set as conditions are set to be pasted in the display screen in the step S2, the measurement data [∠EAB, ∠EBA] The display color is also changed to [Red], which is the same color as the display color of the changed figure (triangle ABE) (step A9).

  Then, it is determined whether or not the coordinates of the movement target point (vertex) E of the triangle ABE that is currently deformed and displayed on the animation screen G3 have reached the coordinates of the movement end point D stored in the animation execution data memory 22h. (Step A10).

  Here, when it is determined that it does not reach (step A10 (No)), the coordinates of the next position of the movement target point (vertex) E are read from the animation execution data memory 22h (step A11).

Thereafter, the processing in steps A4 to A11 is repeated in the same manner, so that the movement target point (vertex) E is moved within the movement range (straight line) CD as shown in FIGS. 5 (D) to 6 (H). The triangle ABE that is sequentially deformed by moving up is displayed, and the measurement data [area: 7.0615 units ² ] recalculated each time is pasted and displayed (steps A4 and A5).

  The display color of the triangle ABE is in accordance with the setting condition [条件 EAB> 90 or ∠EBA> 90] [Then ΔABE: Red] [Else ΔABE: Green] stored in the drawing form condition data memory 22g. , [ＢEAB> 90 or ∠EBA> 90] is changed to [Red] and otherwise changed to [Green] (steps A6 to A9).

  Thereafter, as shown in FIG. 6 (H), the coordinates of the movement target point (vertex) E of the triangle ABE currently deformed and displayed on the animation screen G3 are the movement end points stored in the animation execution data memory 22h. If it is determined that the coordinate of D has been reached (step A10 (Yes)), it is determined whether or not the current execution count has reached the repeat count [Times: 10] stored in the animation setting data memory 22f. (Step A12).

  Here, when it is determined that it has not been reached (step A12 (No)), the number of executions is incremented (+1) (step A13), and the processing after step A3 is similarly repeated (steps A3 to A11). ).

  When it is determined in step A12 that the current number of executions has reached the number of repeats [Times: 10] stored in the animation setting data memory 22f (step A12 (Yes)), the series of graphic displays is performed. Processing is terminated.

Therefore, according to the graphic display function of the first embodiment by the graph scientific calculator 10 having the above-described configuration, on the graphic display screen G, a user-desired graphic (a straight line CD and a triangle ABE having a base AB parallel to the straight line CD) is displayed. In addition to drawing and displaying, the triangle ABE is selected and its measurement data [area: 7.0615 units ² ] is pasted and displayed. Then, the vertex E of the triangle ABE is selected as the movement target point, and the straight line CD is selected as the movement range, and the measurement data and display color condition of the triangle ABE [∠EAB> 90 or ∠EBA> 90] [Then ΔABE: Red ] [Else ΔABE: Green] is set and animation display is executed. Then, the triangle ABE is sequentially deformed and displayed on the animation screen G3 while moving the vertex E on the straight line CD, and the measurement data [area: 7.0615 units ² ] is recalculated and pasted each time. The display color of the triangle ABE is changed to [Red] or [Green] in accordance with the setting condition [∠EAB> 90 or ∠EBA> 90] [Then ΔABE: Red] [Else ΔABE: Green]. Is done.

  Therefore, the user moves the vertex E of the triangle ABE on a straight line CD parallel to the base AB, and the triangle ABE is an obtuse triangle displayed in [Red] or a right-angled or acute-angled triangle displayed in [Green]. Even if it is changed to, it is possible to clearly and effectively learn that the area is always the same as long as the height of the base AB is constant.

  That is, when the animation execution process is started, first, the movement target point (line segment) EH of the graphic change selected on the graphic display screen G, the movement range (straight line) CD, and the animation setting data (22f) The movement target point (line segment) EH is moved on the same movement range (straight line) CD based on the number of divisions [Steps: 9], the movement start point [t0: 0], and the movement end point [t1: 1]. The coordinates of the position of the point are calculated and stored in the animation execution data memory 22h (step A1).

  At this time, since the coordinates of the movement range (straight line) CD are C (5,10) to D (13,10) and the number of divisions is [Steps: 9], the movement target point (line segment) EH is moved. The coordinates of each point to be made are (5, 10) (6, 10) (7, 10) ... (13, 10).

  The number of executions is set to 1 (step A2), and the coordinates (5, 10) of the initial position of the movement target point (line segment) EH (corresponding to the tip C of the straight line CD) are read from the animation execution data memory 22h. (Step A3).

  Then, the coordinates A of the drawing points of the triangles ABE, AHE, and BHE when the line segment EH is translated to the coordinates (5, 10) of the initial position on the graphic display screen G (the tip C of the straight line CD). (5,5), B (11,5), E (5,10), H (5,5) are calculated (step A4).

  Then, the triangles deformed according to the coordinates of the drawing points after the change are drawn with the original colors and line types, and the measurement data [area: Area] [length: Leng] are also reproduced. Calculated and pasted (step A5).

  Then, the measurement data (∠EAB, ∠EBA) of the figure (right triangle AHE, BHE) set in the drawing form condition data memory 22g becomes the drawing data of the deformed current triangles ABE, BHE. Is calculated based on the setting condition [∠EAB = 90] [Then ΔBHE: Green] or [∠EAB <90 and ∠EBA <90] [Then ΔAHE: Cyan] [Then ΔBHE: Green ] Or [∠EBA = 90] [Then ΔAHE: Cyan] or [∠EBA> 90] [Then ΔAHE: Cyan] [Then ΔBHE: Red, EH: Dot Red, BH: Line Red] It is determined whether or not this is true (step A7).

  Here, as shown in FIG. 8 (G), when it is determined that 変 形 EAB = 90 for the right triangle BHE deformed and displayed on the animation screen G3, it is determined that the setting condition is satisfied (step A7 (Yes)). In accordance with the display color [Then ΔBHE: Green] corresponding to the condition [∠EAB = 90], the right triangle BHE is changed to [Green] and displayed (step A8).

  At this time, the display color of the measurement data [Area BHE: 15] [Leng BH: 6] corresponding to the right triangle BHE corresponding to the setting condition is also the same color as the display color of the changed right triangle BHE [Green ] Is displayed (step A9).

  According to this, although the triangle ABE of [Blue] changed to coincide with the right triangle BHE [Green], the length of the line segment EH corresponding to the height of each triangle ABE, BHE [Leng EH: 5] Can be easily confirmed that the area [Area ΔABE: 15] of the triangle ABE of [Blue] is also unchanged.

  Then, whether or not the coordinates of the movement target point (line segment) EH currently displayed on the animation screen G3 has reached the coordinates (13, 10) of the movement end point D stored in the animation execution data memory 22h. Determination is made (step A10).

  Here, when it is determined that it does not reach (step A10 (No)), the coordinates (6, 10) of the position next to the movement target point (line segment) EH are read from the animation execution data memory 22h (step S10). A11).

  Then, the coordinates A (5,5), each drawing point of the triangles ABE, AHE, BHE when the line segment EH is translated in correspondence with the coordinates (6,10) of the next position read out. B (11,5), E (6,10) and H (6,5) are calculated (step A4).

  Each triangle deformed according to the coordinates of each drawing point is drawn with the original color and line type, and the measurement data [area: Area] [length: Leng] is also recalculated. Affixed (step A5).

  Then, the measurement data (∠EAB, ∠EBA) of the figure (right triangle AHE, BHE) set in the drawing form condition data memory 22g becomes the drawing data of the deformed current triangles ABE, BHE. Based on the calculation (step A6), it is determined whether any of the setting conditions is satisfied (step A7).

  Here, as shown in FIG. 8H, 直角 EAB <90 for the right triangle AHE deformed and displayed on the animation screen G3, and ∠EBA <90 for the right triangle BHE, and it is determined that the setting condition is satisfied. (Step A7 (Yes)), the right triangle AHE is displayed in accordance with the display colors [Then ΔAHE: Cyan] and [Then ΔBHE: Green] corresponding to the corresponding conditions [該当 EAB <90 and ∠EBA <90]. [Cyan] and BHE are changed to [Green] and displayed (step A8).

  At this time, the display color of the measurement data [Area △ AHE: 2.5] [Leng AH: 1] corresponding to the right triangle AHE corresponding to the setting condition is also the same color as that of the changed right triangle AHE [Cyan The display color of the measurement data [Area △ BHE: 12.5] [Leng BH: 5] corresponding to the right triangle BHE is also displayed in the same color as the display color of the changed right triangle BHE [Green ] Is displayed (step A9).

  According to this, although the triangle ABE of [Blue] has been changed to be divided into two right triangles AHE [Cyan] and BHE [Green], the length of the line segment EH corresponding to the height of each triangle Since [Leng EH: 5] is unchanged, it can be easily confirmed that the area [Area ΔABE: 15] of the triangle ABE of [Blue] is also unchanged. Moreover, the area [Area △ ABE: 15] of the triangle ABE of [Blue] is the area [Area △ AHE: 2.5] of the right triangle AHE [Cyan] that bisects the area [Area △ BHE: It can be easily confirmed that it matches the sum of [12.5].

  Thereafter, the same processing is repeated, and when the coordinates (8, 10) of the next position of the movement target point (line segment) EH are read from the animation execution data memory 22h in step A11, FIG. ), The triangles ABE, AHE, and BHE are simultaneously changed and displayed (steps A4 to A9).

  In this case as well, the [Blue] triangle ABE has the same length [Leng EH: 5] as the line segment EH corresponding to the height of each triangle. It is easy to confirm that the area [Area △ ABE: 15] is unchanged, and the area [Area △ AHE: 7.5] of the right triangle AHE [Cyan] and the area [Area △ of BHE [Green] that bisects the area [Area △ ABE: 15]. BHE: 7.5] can be easily confirmed to match the total.

  Thereafter, the same processing is repeated, and in step A11, the coordinates (11, 10) of the next position of the movement target point (line segment) EH are read from the animation execution data memory 22h. ), The triangle ABE of [Blue] is changed and displayed so as to coincide with the right triangle AHE [Cyan] (steps A4 to A9).

  According to this, although the triangle ABE of [Blue] changed to coincide with the right triangle AHE [Cyan], the length of the line segment EH corresponding to the height of each triangle ABE, AHE [Leng EH: 5] Can be easily confirmed that the area [Area ΔABE: 15] of the triangle ABE of [Blue] is also unchanged.

  Thereafter, the coordinates A (5) of the respective drawing points of the triangles ABE, AHE, and BHE when the line segment EH is translated in correspondence with the coordinates (12, 10) of the next position read in step A11. , 5), B (11,5), E (12,10), H (12,5) are calculated (step A4).

  Each triangle deformed according to the coordinates of each drawing point is drawn with the original color and line type, and the measurement data [area: Area] [length: Leng] is also recalculated. Affixed (step A5).

  Then, the measurement data (∠EAB, ∠EBA) of the figure (right triangle AHE, BHE) set in the drawing form condition data memory 22g becomes the drawing data of the deformed current triangles ABE, BHE. Based on the calculation (step A6), it is determined whether any of the setting conditions is satisfied (step A7).

  Here, as shown in FIG. 9K, when it is determined that the right triangle ABE deformed and displayed on the animation screen G3 is ∠EBA> 90 and the setting condition is satisfied (step A7 (Yes)), the corresponding condition The right triangle AHE is [Cyan] and BHE is [Red] according to the display color [Then ΔAHE: Cyan] [Then ΔBHE: Red, EH: Dot Red, BH: Line Red] according to [∠EBA> 90]. The vertical side EH of the BHE is changed to [Dot Red] and the bottom side BH is changed to [Line Red] (step A8).

  At this time, the display color of the measurement data [Area BHE: 5] [Leng BH: 2] corresponding to the right triangle BHE corresponding to the setting condition is also the same color as the display color of the changed right triangle BHE [Red ] Is displayed (step A9).

  According to this, the triangle [A] of [Blue] is the same as that of [Blue] because the length [Leng EH: 5] of the line segment EH corresponding to the height of each triangle is unchanged. It can be easily confirmed that the area [Area △ ABE: 15] of the triangle is also unchanged, and the area [Area △ ABE: 15] of the triangle ABE of [Blue] is the length [Leng of the base AB of the triangle ABE] It is easy to confirm that it matches the value obtained by subtracting the area [Area △ BHE: 2.5] of BHE [Red] from the area [Area △ AHE: 17.5] of the right triangle AHE [Cyan] that has changed beyond AB: 6]. it can.

  Thereafter, the same processing is repeated, and in step A11, the coordinates (13, 10) of the position next to the movement target point (line segment) EH from the animation execution data memory 22h (corresponding to the end D of the straight line CD). As shown in FIG. 9L, the triangles ABE, AHE, and BHE are simultaneously changed and displayed (steps A4 to A9).

  In this case as well, the [Blue] triangle ABE has the same length [Leng EH: 5] as the line segment EH corresponding to the height of each triangle. It is easy to confirm that the area [Area △ ABE: 15] is unchanged, and the area [Area △ ABE: 15] exceeds the length [Leng AB: 6] of the base AB of the triangle ABE. It can be easily confirmed that it matches the value obtained by subtracting the area [Area ΔBHE: 5] of BHE [Red] from the area [Area ΔAHE: 20] of the changed right triangle AHE [Cyan].

  Then, it is determined that the coordinates of the movement target point (line segment) EH of the triangle ABE that is currently deformed and displayed on the animation screen G3 have reached the coordinates of the movement end point D stored in the animation execution data memory 22h. (Step A10 (Yes)), it is determined whether or not the current number of executions has reached the number of repeats [Times: 10] stored in the animation setting data memory 22f (Step A12).

  Here, when it is determined that it has not been reached (step A12 (No)), the number of executions is incremented (+1) (step A13), and the processing after step A3 is similarly repeated (steps A3 to A11). ).

  When it is determined in step A12 that the current number of executions has reached the number of repeats [Times: 10] stored in the animation setting data memory 22f (step A12 (Yes)), the series of graphic displays is performed. Processing is terminated.

  Therefore, according to the graphic display function of the second embodiment by the graph scientific calculator 10 having the above-described configuration, on the graphic display screen G, the user-desired graphic (the straight line CD and the triangle ABE having the base AB parallel to the straight line CD and this Is drawn and displayed, and the length [Leng EH] of the vertical side EH corresponding to the height of each triangle and the length [Leng AB] [Leng AH] [ Leng BH], area [Area ΔABE] [Area ΔAHE] [Area ΔBHE] are displayed as measurement data. Then, the vertical side EH is selected as the object to be moved, and the straight line CD is selected as the parallel movement range thereof, and the measurement data and display color condition for each triangle ([∠EAB = 90 Then ΔBHE: Green] [∠EAB <90 and ∠ EBA <90 Then △ AHE: Cyan, △ BHE: Green] [∠EBA = 90 Then △ AHE: Cyan] [∠EBA> 90 Then △ AHE: Cyan, △ BHE: Red, EH: Dot Red, BH: Line Red ]) To execute animation display. Then, on the animation screen G3, each of the triangles ABE, AHE, BHE is displayed while being deformed while the line segment EH is translated along the straight line CD, and the measurement data [Leng] [Area] is recalculated each time. And pasted. Then, according to the setting conditions, the display colors of the right triangles AHE and BHE and the measurement data [Leng] [Area] are changed to the corresponding [Cyan] [Green] [Red] and displayed.
