  FIG. 6 is a flowchart showing a setting state writing process associated with the entire process in the graphic proof problem answer mode of the graph scientific calculator 10.

  FIG. 7 is a diagram showing a graphic display operation (part 1) associated with the overall processing in the graphic proof problem answer mode of the graph scientific calculator 10.

  When the proof question answer mode is selected and determined according to the menu selection screen (not shown) of the operation mode displayed on the color display unit 16 according to the user operation (step S1), it is stored in the drawing figure storage unit 22b. A graphic selection menu (not shown) for selecting the various graphic proof problems is displayed.

  When an arbitrary graphic proof problem is selected according to this graphic selection menu, drawing data of the selected graphic proof problem is read out, for example, as shown in FIG. The figure of the proof problem formed by dropping the perpendicular line BP, CQ on the straight line 1 from the other two vertices B, C of the triangle ABC and the right triangle ABC with A is a feature point (A, B, C, etc.) are added and displayed in the graphic display area 16a of the color display unit 16 (proof problem display screen) (step S2).

  In the figure of the proof problem shown in FIG. 7A, states such as sides and angles set in the figure are stored in the proposition state information storage unit 22b1, and based on this, the right triangle ABC, the perpendicular BP, Each CQ is displayed with a right-angle symbol added.

  In this way, when the graphic of the user's arbitrary proof problem is selected and displayed, the process proceeds to the graphic element selection process in FIG. 4 (step SA).

  In the state shifted to the graphic element selection process, as shown in FIG. 7B, when the side AB in the right triangle ABC in the displayed graphic is selected by the pen touch T (step A1 (Yes )), The side AB of the selected graphic element is highlighted and identified, and is stored in the graphic element storage unit 22b3 (step A2).

  Then, it is determined whether or not the moving direction of the pen touch T has been input on the side AB of the graphic element touched by the pen touch T (step A3).

  Here, when it is determined that there is no moving direction of the pen touch T on the side AB (step A3 (No)), the notation name of the selected side AB is the character “A associated with the side AB. "B" is stored in the graphic element name storage unit 22b4 as a notation name "AB" according to the arrangement order (alphabetically) (step A4b).

  On the other hand, the movement direction “B → A” of the pen touch T from the point B side to the point A side is input on the side AB of the graphic element touched by the pen touch T, as indicated by an arrow x in FIG. If it is determined (step A3 (Yes)), the notation name of the selected side AB is stored as the notation name “BA” in the order corresponding to the direction input to the side AB. Stored in the part 22b4 (step A4a).

  Then, as shown in FIG. 7D, a writing operation is performed by pen touching the character / expression display area 16b labeled << Proof Space >> on the color display unit 16 (proof problem display screen). If it is determined (step A5 (Yes)), the notation name “BA” of the graphic element (side AB) temporarily stored in the graphic element name storage unit 22b4 is read and shown in FIG. As described above, it is displayed in the character / formula display area 16b which is the << proof space >> (step A6).

  Thereafter, when it is determined that another graphic element is selected in the graphic being displayed on the color display unit 16 (proof problem display screen) (step A7 (Yes)), the process returns to the processing after step A2. The selected graphic element is identified and displayed (step A2).

  Therefore, according to the graphic element selection function in the graphic proof problem answering mode of the graph scientific calculator 10 having the above-described configuration, any arbitrary graphic in the graphic can be selected among arbitrary graphic displayed on the color display unit 16 (proof problem display screen). When the graphic element is selected and identified and displayed by the pen touch T, the notation name of the selected graphic element is in a predetermined arrangement order according to the character type of each character added to the graphic element, or the pen touch T Are displayed together with the graphic in the order of each character according to the moving direction.

  As a result, the selected graphic element can be immediately converted into a character string with a notation name corresponding to the selection method and displayed by simply selecting with a pen touch T for each graphic element of the displayed graphic. Can do.

  FIG. 8 is a diagram showing a graphic display operation (part 2) that accompanies the overall processing in the graphic proof problem answer mode of the graph scientific calculator 10.

  As shown in FIG. 8A, a user-provided proof problem figure called from the drawing figure storage unit 22b (same as FIG. 7A) is displayed in the figure display area 16a of the color display unit 16 (step S1, S2), and according to the graphic element selection process (step SA) in FIG. 4, as shown in FIG. 8B, the side AB and the side AC of the right triangle ABC are pen touched T1, T2 to identify and display h1, h2. (Steps A1 and A2).

  Here, when the input in the direction of the pen touches T1 and T2 along the side AB and the side AC of the right triangle ABC is not determined (step A3 (No)), the side AB and the side AC which are the selected graphic elements are determined. Are stored in the graphic element name storage unit 22b4 as "AB" and "AC" in the arrangement order corresponding to the character type appended to each side (step A4b).

  Thereafter, the process proceeds to the state setting process in FIG. 5 without performing the writing operation of the notation name of the selected graphic element and the selection operation of other graphic elements (step A5 (No) → A7 (No)). (Step SB), the side “AB” and the side “AC” of the right triangle ABC identified and displayed as the selected graphic element, as shown in FIG. A state setting window WJ for setting the above relationship is displayed over the figure display area 16a (step B1).

  In this state setting window (relationship between two sides) WJ, for example, when the item “equal length” is selected and designated by the cursor Cu (step B1 (Yes)), the two sides set by the selection item State (condition) “length is equal” is stored in the user setting state information storage unit 22b2 in association with the two sides “AB” and “AC” of the graphic elements identified and indicated by h1 and h2. Then, as shown in FIG. 8D, the setting state (condition) “length is equal” is reflected on the two sides “AB” and “AC” displayed in the identification indications h1 and h2. The display is updated by adding equal symbols e1 and e2 (step B2).

  Thereafter, when the process proceeds to the setting state writing process in FIG. 6 (step SC), as shown in FIG. 8E, the setting state (condition) “equal length” is reflected by the equal symbols e1 and e2. A proof discharge window WD for writing a proof expression (solution) of the graphic elements (sides “AB” and “AC”) identified and displayed h1 and h2 is displayed superimposed on the graphic display area 16a ( Step C1).

  In this proof discharge window WD, when the item “Yes” for instructing the writing of the proof expression (solution) is selected and instructed by the cursor Cu (step C1 (Yes)), it is stored in the graphic element name storage unit 22 b 4 The notation names “AB” and “AC” of the created graphic elements (sides “AB” and “AC”) are associated with the graphic elements (sides “AB” and “AC”) and stored in the user setting state information storage unit. A proof expression (solution) “AB = AC” reflecting the setting state (condition) “length is equal” stored in 22b2 is generated. Then, as shown in FIG. 8 (F), the generated proof formula (solution) in the character / formula display area 16b written as << Proof space >> on the color display section 16 (proof question display screen). “AB = AC” is displayed (step C2).

  At this time, the setting state (condition) “length is equal” reflected in the proof formula (solution) “AB = AC” is the setting by the user, that is, stored in the user setting state information storage unit 22b2. When it is determined that the setting state (condition) is established (step C3 (Yes)), a message (assuming) indicating the user setting is added to the proof expression (solution) “AB = AC”. It is displayed (step C4).

  On the other hand, the setting state (condition) “length is equal” reflected in the proof formula (solution) “AB = AC” is not the setting by the user, that is, the setting stored in the user setting state information storage unit 22b2. When it is determined that it is not a state (condition) but a setting state (condition) stored in advance in association with the graphic of the proof problem currently displayed in the proposition state information storage unit 22b1 (step C3 ( No)), a message (assuming) indicating that the user setting is not added (RETURN).

  Therefore, according to the graphic element selection function, the state setting function, and the setting state writing function in the graphic proof problem answer mode of the graph scientific calculator 10 having the above-described configuration, any user displayed on the color display unit 16 (proof problem display screen) can be selected. In the figure, an arbitrary figure element (side “AB” “AC”) in the figure is selected by pen touches T1, T2 to be identified and displayed h1, h2, and the selected figure element (side “AB” “AC” is selected. )) State (condition) can be set, for example, as [equal length] according to the user operation based on the state setting window (relationship between two sides) WJ. Then, the equal symbols e1 and e2 reflecting the state (condition) [equal length] set in the selected graphic element (sides “AB” and “AC”) of the graphic being displayed are additionally displayed. Further, the proof formula (solution) “AB = AC” is written and displayed.

  When the state (condition) [equal length] set for the selected graphic element (sides “AB” and “AC”) is the state (condition) set by the user, the proof formula ( Solution: A message (assuming) indicating that is added to “AB = AC”.

  As a result, it is possible to easily set the user's arbitrary state (condition) regarding the length, angle, etc. of the side of the selected graphic element simply by directly pen-touching and selecting each graphic element of the displayed graphic. In addition to being able to be displayed and updated, it can be immediately converted into a character string such as a notation name or a certification expression of the graphic element reflecting the state (condition) set in the graphic element and displayed.

  Therefore, the state (condition) set for the graphic can be easily written out as character information, and the graphic can be learned more effectively.

  In the above-described embodiment, the state set to the selected graphic element has been described by setting, for example, a state where the lengths of two sides are equal (“AB = AC”) with respect to the length and angle of the side. Needless to say, the same function can be achieved with respect to other setting states such as equal angles, congruence / similarity of figures, and the like.
