  The setting data memory 144 stores setting data for various calculation display modes set according to the [SHIFT] + [MODE] (= [SETUP]) key operation of the key input unit 11. As setting data of this calculation display mode, for example, display mode “1: LineIO (single line display) mode / 2: MthIO (textbook display) mode”, angle calculation mode “3: deg (degree) mode / 4: rad (Radian) mode / 5: gra (grad) mode ", rounding calculation mode" 6: Fix (fixed number of decimal places) mode / 7: Sci (specified number of significant digits) mode / 8: Norm mode: no rounding ", The setting data of various calculation display modes such as are stored. In the setting data memory 144, a predetermined initial setting mode is set in the initial state. Specifically, initial setting modes such as a display mode (MthIO (textbook display) mode), an angle calculation mode (deg (degree) mode /), and a rounding calculation mode (Norm: no rounding) are stored. Then, for example, when the “4” key is pressed after operating the [SHIFT] + [MODE] (= [SETUP]) key, the angle mode (3: deg (degree) mode) is changed to the angle mode (4: rad (radian)). ) Mode) and the angle mode is registered.

  The variable value memory 145 is a memory area in which different numerical values are individually stored for nine characters of A, B, C, D, E, F, M, X, and Y. In the initial state, All “0” are stored. For example, by performing key operations such as the [3] key, [SHIFT] + [RCL] key (= [STO] key), and [(−)] key (= [A] key) of the key input unit 11. The variable memory A of the variable value memory 145 is designated, and the variable value “3” is set.

  The camera-equipped communication device E captures the QR code displayed and output on the display output unit 12 of the scientific calculator 10 and transmits the QR code to the calculation server 20 via the communication network N according to the content (QR data) of the captured QR code. Send data.

  FIG. 3 is a block diagram showing the configuration of the electronic circuit of the calculation server 20.

  The electronic circuit of the calculation server 20 includes a CPU 21 that is a computer, a memory 22, a recording medium 23, a recording medium reading unit 24, and a communication unit 25. Further, as indicated by a broken line in the figure, a key input unit 26 or a display output unit 27 may be provided.

  The CPU 21 is stored in the memory 22 in advance, or is read from the recording medium 23 such as a memory card into the memory 22 via the recording medium reading unit 24, or the communication unit 25 is transmitted from the Web server on the communication network N. The operation of each part of the circuit is controlled according to the server control program 221 downloaded to the memory 22 through the communication unit 25, and various arithmetic processes are executed according to the received QR data from the camera-equipped communication device E received by the communication unit 25.

  In addition to storing the server control program 221, the memory 22 has a received QR data memory 222 that stores QR data received via the communication unit 25 for each received QR data.

  The server control program 221 displays a function for performing a setting operation or a maintenance operation according to a setting operation or a maintenance operation of the key input unit 26 of the operator of the calculation server 20, a progress or result of the operation, and a display output unit 27. It has a function to display on the screen.

  In the calculation server 20 configured as described above, the CPU 21 controls the operation of each part of the circuit in accordance with the instructions described in the server control program 221, and the software and hardware operate in cooperation with each other. As described in the explanation of the operation, a server processing function is realized in which a mathematical expression is calculated based on the received QR data, and the calculation result is transmitted to the camera-equipped communication device E which is the transmission source of the received QR data. When the received QR data includes information for specifying another communication device as the transmission destination of the calculation result, or when the transmission destination is specified in advance in association with the unique ID of the scientific calculator 10 The calculation result can be transmitted to a device other than the camera-equipped communication device E as the transmission source.

  The camera-equipped communication device E displays the calculation result received from the calculation server 20 via the communication network N on the display output unit ED, or connects the projector P to the camera-equipped communication device E to calculate the calculation result. Can be projected and output.

  Next, the display control function of the scientific calculator 10 having the above configuration will be described with reference to the flowchart of the display control process of FIG.

  When the key input unit 11 is operated, the CPU 13 of the scientific calculator 10 determines whether or not it is a setting data change operation, that is, whether or not it is a [SHIFT] + [MODE] (= [SETUP]) key operation. Is determined (step S101). If it is determined that the operation is not a setting data change operation, the CPU 13 determines whether or not the operation of the key input unit 11 is an execution operation of the function table function, that is, the function table selection operation by the [MODE] key operation. It is determined whether or not there is (step S102). If it is determined that the operation is not an execution operation of the function table function, the CPU 13 determines whether or not the operation of the key input unit 11 is a variable input operation, that is, [SHIFT] + [RCL] (= [STO]). It is determined whether or not the operation is a key operation (step S103). If it is determined that this is not a variable input operation, the CPU 13 executes another process.

  If it is determined in step S101 that the operation is a setting data change operation, the CPU 13 causes the display output unit 12 to display a change screen for changing and setting a plurality of types of setting data for the display calculation of the mathematical expression. Specifically, the display setting mode is “1: MthIO (natural display) 2: LineIO (line display)”, and the angle calculation setting mode is “3: Deg (angle setting: degree) 4: Rad (angle setting) : Radian) 5: Gra (angle setting: grad) ”,“ 6: Fix (fixed number of decimal places) mode ”/ 7: Sci (specified number of significant digits) mode / 8: Norm mode: "No rounding" is displayed (step S104). Then, the content of the setting data memory 144 of the memory 14 is changed to a mode set by a user operation (number input using a numeric key) of the key input unit 11. Specifically, when the user performs an operation of pressing the numeric key “4”, the content of the angle mode in the setting data memory 144 of the memory 14 is changed and set to radians (step S105). Thereafter, the CPU 13 returns the process to step S101.

  On the other hand, if it is determined in step S103 that the operation is a variable input operation, the CPU 13 receives a variable value specified by a user input operation of the key input unit 11 and receives a variable value (step S106). The input variable value is set in the variable value memory 145 of the 14 designated variables (step S107). Thereafter, the CPU 13 returns the process to step S101.

  If it is determined in step S102 that the operation is a function table function execution operation, the CPU 13 stores the “function table function” in the execution function memory 146 of the memory 14 and the user operation of the key input unit 11. The input of the mathematical expressions 1 and 2 is received (step S108). This is because the display of the function expression 1 is first displayed on the display output unit 12 in accordance with the execution operation of the function table function by displaying “f (x) =” for inputting the expression of the function expression 1. Prompt for Then, the user operates the key input unit 11 to input a function expression “(A + B) x” that is an expression including variables A and B, for example, as shown in FIG. The [=] key is operated. As a result, “f (x) = (A + B) x” is registered as the function formula 1 in the formula data memory 147 of the memory 14. Subsequently, the CPU 13 prompts the user to input the mathematical expression of the function expression 2 by displaying “g (x) =” for inputting the function expression 2 on the display output unit 12. Then, the user operates the key input unit 11 to input a function expression “(A + C) x” that is an expression including variables A and C, for example, as shown in FIG. ] Key. As a result, “g (x) = (A + C) x” is registered as the function expression 2 in the mathematical formula data memory 147 of the memory 14.

  Thereafter, the CPU 13 determines whether or not the [QR] key of the key input unit 11, that is, the [SHIFT] + [OPTN] key is pressed (step S109). If it is determined that the [QR] key has been pressed, the CPU 13 advances the process to step S113 described later.

  On the other hand, when it is determined that the [QR] key has not been pressed, the CPU 13 determines the calculation range (initial value, final value, step (increment)) of the function expression by the user operation of the key input unit 11. An input is received (step S110). That is, the CPU 13 prompts the user to input an initial value by first displaying “Start?” For input of an initial value on the display output unit 12. Then, the user operates the key input unit 11 to input a numerical value [1] as an initial value, for example, as shown in FIG. 5C, and then operates the [=] key. As a result, “1” is registered in the other data memory 148 of the memory 14 as an initial value. Subsequently, the CPU 13 prompts the user to input the final value by displaying “End?” For displaying the final value on the display output unit 12. Then, the user operates the key input unit 11 to input a numerical value [4] as a final value, for example, as shown in FIG. 5D, and then operates the [=] key. As a result, “4” is registered as the final value in the other data memory 148 of the memory 14. Thereafter, the CPU 13 prompts the user to input the increment by displaying “Step?” For the increment input on the display output unit 12. Then, the user operates the key input unit 11 to input a numerical value [1] as an increment, for example, as shown in FIG. 5E, and then operates the [=] key. As a result, “1” is registered in the other data memory 148 of the memory 14 as a step.

  When the calculation range of the function formula is input in this way, the CPU 13 stores the function formula stored in the formula data memory 147 of the memory 14, the calculation range stored in the other data memory 148, and the variable value memory 145. The function table is calculated on the basis of the variable and the calculation result is displayed and output to the display output unit 12 according to the setting mode stored in the setting data memory 144 (step S111).

  Thereafter, the CPU 13 determines whether or not the [QR] key of the key input unit 11, that is, the [SHIFT] + [OPTN] key is pressed (step S112). If it is determined that the [QR] key has been pressed, the CPU 13 advances the process to step S113 described later. On the other hand, if it is determined that the [QR] key has not been pressed, the CPU 13 returns the process to step S101.

  If it is determined in step S109 or step S112 that the [QR] key has been pressed, the CPU 13 executes necessary information detection processing (step S113).

  FIG. 6A shows a flowchart of this necessary information detection process.

  That is, in this necessary information detection process, the CPU 13 first determines whether or not there is a variable in the input formula stored in the formula data memory 147 of the memory 14 (step S113A). If it is determined that there is no variable, the CPU 13 further determines whether or not a trigonometric function is included in the input formula (step S113B). If it is determined that the trigonometric function is not included, the CPU 13 returns the process to the upper routine.

  If it is determined in step S113A that there is a variable, for example, in the above example, since there are variables A, B, and C, the CPU 13 determines the values of the variables in the input formula, for example, “1”, “4”. ”And“ 3 ”are extracted from the variable value memory 145 of the memory 14, and the extracted data is stored as extracted data in the work area 149 of the memory 14 (step S113C). Thereafter, the CPU 13 advances the process to step S113B.

  If it is determined in step S113B that a trigonometric function is included, the CPU 13 extracts the set angle mode (deg mode / rad mode / gra mode) from the setting data memory 144 of the memory 14, The extracted data is stored as extracted data in the work area 149 of the memory 14 (step S113D). Thereafter, the CPU 13 returns the processing to the upper routine. Note that when the calculation result is a decimal, rounding mode setting data for setting whether or not to round the decimal is necessary. The extracted data is also extracted into the work area 149 as the extracted data together with the rounding mode setting data. May be stored. Further, the setting data in the setting data memory 144 may be collectively stored as extracted data in the work area 149 as extracted data.

  Here, an example in which a trigonometric function is included in the function expression is shown in FIG.

  In step S108, when the [sin] key is operated as shown in FIG. 7A in response to the display “f (x) =” for the input of the function expression 1, the display is “f (x)”. = Sin (", then the [x] key ([ALPHA] + [)] key) and the [)] key are operated, and then the [=] key that is the execution key is operated, whereby the mathematical formula data in the memory 14 “F (x) = sin (x)” is registered in the memory 147 as the function expression 1. Subsequently, when the [cos] key is operated as shown in FIG. 7B with respect to the display “g (x) =” for inputting the function expression 2, the display is “g (x) = cos ( Then, after the [x] key ([ALPHA] + [)] key) and the [)] key are operated, the [=] key that is the execution key is operated, whereby the mathematical formula data memory 147 of the memory 14 is stored. “G (x) = cos (x)” is registered as the function expression 2.

  Thereafter, in step S110, in response to the display “Start?” For inputting an initial value, as shown in FIG. 7C, after inputting a numerical value [0] as an initial value, the [=] key is pressed. By operating, “0” is registered in the other data memory 148 of the memory 14 as an initial value. Subsequently, in response to the display “End?” For inputting the final value, as shown in FIG. 7D, after the numerical values [3] [6] [0] as the final values are input, [=] By operating the key, “360” is registered as the final value in the other data memory 148 of the memory 14. Thereafter, in response to the display “Step?”, As shown in FIG. 7E, after the numerical value [9] [0] as an increment is input, the [=] key is operated to “90” is registered in the data memory 148 as a step.

  When such an input is performed, it is determined in step S113A that there is no variable, but in step S113B, it is determined that a trigonometric function is included. For example, if the deg mode is set in step S105, the deg mode, which is the set angle mode, is extracted from the setting data memory 144 of the memory 14 in the step S113D, and the memory 14 Are stored in the work area 149 as extracted data.

  When the necessary information detection process in step S113 is completed, the CPU 13 stores the address of the calculation server 20, the unique ID of the scientific calculator 10 stored in the unique ID 142 of the memory 14, and the execution function memory 146. Function type (for example, function table function), function-specific calculation data (for example, a function formula stored in the formula data memory 147 and a calculation range stored in the other data memory 148), a work area 149 The extracted data (for example, the angle mode extracted from the setting data memory 144 and the variable value extracted from the variable value memory 145) and others are QR-coded and displayed on the display output unit 12 (step S114).

  As a result, the QR code is displayed and output on the display output unit 12 as shown in FIG. The content of the QR code in FIG. 5F is as shown in FIG. Further, the contents of the QR code in FIG. 7F are as shown in FIG.

  Thereafter, the CPU 13 determines whether or not there is a re-input of the function formula (step S115). If it is determined that there is no re-input, the CPU 13 returns the process to step S101.

  On the other hand, if it is determined that there is a re-input, the CPU 13 returns the process to step 108. Then, as described above, an input of a new function expression is accepted. If it is not necessary to change the calculation range in the new function formula, the [QR] key, that is, the [SHIFT] + [OPTN] key is pressed in step S109, so that the CPU 13 performs the process in step S113. Will proceed.

  Next, the server processing function of the calculation server 20 having the above configuration will be described with reference to the server processing flowchart of FIG.

  The CPU 21 of the calculation server 20 first determines whether or not to process QR data (step S201). Here, when it is determined that other processing is performed without performing the QR data processing, the CPU 21 proceeds to other processing.

  On the other hand, when it is determined that the QR data processing is to be performed, the CPU 21 waits for the communication unit 25 to receive QR data obtained by the QR operation of the camera-equipped communication device E (step S202). That is, in the scientific calculator 10, the QR code is displayed on the display output unit 12 by the above-described display control process, and when the QR code is photographed by the electronic device E with the camera, the content (QR data) of the QR code is decoded and calculated. Access to the address of the server 20 becomes possible. Then, in response to the user's operation of the camera-equipped electronic device E, the camera-equipped electronic device E transmits the QR data to the address calculation server 20 via the communication network N. In step S202, the calculation server 20 waits for reception of QR data from the electronic device E with camera.

  If it is determined that the QR data has been received, the CPU 21 receives the received QR data, that is, the unique ID of the scientific calculator 10, the function type (for example, the function table function), the function-specific calculation data (for example, the function formula and the calculation range), Extracted data (for example, angle mode and variable value) and the like are stored in the reception QR data memory 222 of the memory 22 (step S203). Then, processing corresponding to the function type is performed using the function expression and extracted data of the stored QR data (step S204). For example, in the case of the function table function, the calculation range is calculated, and the table that is the calculation result is transmitted to the transmission source camera-equipped electronic device E via the communication network N. Thereby, the camera-equipped electronic device E that has captured the QR code displayed and output on the display output unit 12 of the scientific calculator 10 receives the table as a result of the calculation, and receives the table of FIG. 6B or FIG. 6C. Can be displayed on the display output unit ED. 6B shows the result calculated from the QR data in FIG. 5G, and FIG. 6C shows the result calculated from the QR data in FIG. 7G.

  Subsequent to the process in step S204, the CPU 21 executes a mathematical expression / detected data matching confirmation process (step S205).

  FIG. 9 shows a flowchart of this mathematical expression and detection data matching confirmation processing.

  That is, in this mathematical expression and detection data matching confirmation process, the CPU 21 first determines whether or not there is a variable in the input mathematical expression in the received QR data stored in the received QR data memory 222 of the memory 22. In the following processing, the input formula includes a function formula, an initial value, an end value, and a step value (step S205A). If it is determined that there are no variables in the input formula (function formula and initial value, end value, step value), the CPU 21 further determines whether or not the input formula includes a trigonometric function (step S203B). If it is determined that the trigonometric function is not included, the CPU 21 returns the process to the upper routine.

  If it is determined in step S205A that there is a variable, for example, the QR data in FIG. 5G, the CPU 21 sets a value in the extracted data in the received QR data stored in the received QR data memory 222. It is determined whether or not there is a variable of “0” (step S205C). When it is determined that there is no variable having a value of “0” as in the QR data in FIG. 5G, the CPU 21 advances the process to step S205B.

  On the other hand, if it is determined that there is a variable whose value is “0”, the CPU 21 determines that the processing result in step S204 is incorrect or cannot be processed, and the CPU 21 determines that the variable has a value “0”, for example. Is A, the variable value of variable A may not have been entered. Messages such as “Enter Yes / No” are communicated by communication unit 25 via communication network N to the camera-equipped communication. It transmits to the apparatus E (step S205D). And it is discriminate | determined by the communication part 25 whether "Yes" was received from the communication apparatus E with a camera (step S205E). If it is determined that “Yes” has not been received, that is, “No” has been received, the CPU 21 advances the process to step S205B.

  On the other hand, if it is determined that “Yes” is received, the CPU 21 sends a message such as “Please input the variable value of the variable A” to the transmission source via the communication network N by the communication unit 25. To the camera-equipped communication device E (step S205F). Upon receipt of this message, the camera-equipped communication device E displays and outputs the message as an alarm display on the display output unit ED, and the user who confirms the message inputs the missing variable value on the camera-equipped communication device E. Then, an operation of transmitting the input variable value to the calculation server 20 is performed. Therefore, after transmitting the message, the CPU 21 waits for the communication unit 25 to receive a variable value from the camera-equipped communication device E (step S205G). If a variable value is received, the received QR data is updated by writing the received variable value in the corresponding received QR data memory 222 of the memory 22 (step S205H). Thereafter, the CPU 21 advances the processing to step S205B.

  On the other hand, if it is determined in step S205B that a trigonometric function is included as in the QR data of FIG. 7G, for example, the CPU 21 extracts the extracted data in the received QR data stored in the received QR data memory 222. It is determined whether or not the angle mode is degree (Deg) (step S205I). If it is determined that the angle mode is degrees, the CPU 21 determines whether or not the setting value of the function argument is a multiple of 15 (degrees). Note that the setting value of the function argument is calculated at the time of each step calculation in the formula of the input formula (function formula and initial value, end value, step value) as well as the setting value directly input as an argument in the formula. The set value of the argument to be included is included (step S205J). If it is determined that it is a multiple of 15 (degrees), the CPU 21 returns the processing to the upper routine. On the other hand, if it is determined that it is not a multiple of 15 (degrees), the CPU 21 advances the processing to step S205N described later, assuming that the processing result of step S204 is incorrect or cannot be processed.

  If it is determined in step S205I that the angle mode is not degree, the CPU 21 determines whether the angle mode is radians (Rad) (step S205K). If it is determined that the angle mode is radians, the CPU 21 determines whether the setting value of the function argument is a multiple of π / 12 (radians) (step S205L). If it is determined that it is a multiple of π / 12 (radian), the CPU 21 returns the process to the upper routine. On the other hand, if it is determined that it is not a multiple of π / 12 (radian), the CPU 21 determines that the process result in step S204 is incorrect or cannot be processed, and the process proceeds to step S205N described later. Proceed.

  If it is determined in step S205K that the angle mode is not radians, the CPU 21 determines that the angle mode is Grad, and the function argument setting value is 50/3 (Grad). ) Is determined (step S205M). If it is determined that it is a multiple of 50/3 (Grade), the CPU 21 returns the processing to the upper routine. On the other hand, if it is determined that it is not a multiple of 50/3 (Grade), the CPU 21 determines that the processing result in Step S204 is incorrect or cannot be processed, and the process proceeds to Step S205N described later. Proceed.

  In step S205N, the CPU 21 determines that the “(angle mode) setting may be incorrect. ○ DEG ○ RAD ○ GRA” and other correction screens (the current angle mode setting value is not a white circle but a black circle). Is transmitted to the communication device E with a camera as the transmission source by the communication unit 25 via the communication network N.

  For example, in the scientific calculator 10, a triangle “f (x) = sin (x)” as shown in FIG. 10A and “g (x) = cos (x)” as shown in FIG. 10B. The function is input with the angle mode set to radians (Rad) as indicated by the mode icon 121 being “R”, and the initial value “0” as shown in FIG. 10C. 10D, when the final value “270” is registered as shown in FIG. 10D and step “90” is registered as shown in FIG. 10E, and QR coding is performed as shown in FIG. QR data such as 10 (G) is stored in the received QR data memory 222 of the memory 22 of the calculation server 20. Then, when the process of step S204 is performed with the received QR data, a table as shown in FIG. 11A is displayed as a calculation result on the display output unit ED of the communication device E with the camera as the transmission source. become.

  In this case, it is determined in step S205K that the angle mode is radians (Rad), and in step S205L, it is determined that the function argument, that is, the set value of the calculation range is not a multiple of π / 12 (radians). Therefore, in this step S205N, the correction screen is transmitted to the camera-equipped communication device E, and an alarm display AL as shown in FIG. 11A is displayed and output on the display output unit ED of the communication device E.

  The user who has confirmed such an alarm display AL corrects the setting to the correct angle mode on the communication device E with the camera, as shown in FIG. Perform the operation to send.

  Therefore, the CPU 21 of the calculation server 20 waits for the communication unit 25 to receive a setting value from the camera-equipped communication device E after executing the process of step S205N (step S205O). Here, if the set value is received, the angle mode of the reception QR data memory 222 corresponding to the received set value is updated (step S205P). Thereafter, the CPU 21 returns the processing to the upper routine.

  When the mathematical expression in step S205 and the detected data matching confirmation process are completed, the CPU 21 determines whether or not the data has been updated in the received QR data memory 222 of the memory (step S206). If it is determined that no data has been updated, the CPU 21 ends the QR data processing and returns the processing to step S201.

  On the other hand, if it is determined that the data has been updated, the CPU 21 performs a process according to the function type using the function expression or extracted data of the updated QR data (step S207). For example, in the case of the function table function, the calculation range is recalculated, and the table as the calculation result is retransmitted by the communication unit 25 via the communication network N to the transmission source camera-equipped electronic device E. Thereby, the camera-equipped electronic device E in which the variable value is input or the set value is corrected receives the table that is the retransmitted calculation result and displays the display output as shown in FIG. 11C, for example. It can be displayed on the part ED. Thereafter, the CPU 21 ends the QR data processing and returns the processing to step S201.

  In the above description, the case where the calculation of the functional expression is executed by the calculation server 20 has been described as an example. However, the function of the calculation server 20 is provided in the form of an application that can be realized by the communication device E with a camera, for example, a smartphone. Of course, it may be.

  Therefore, according to the scientific calculator 10 having the above-described configuration, the variable value memory 145 stores variable values for a plurality of variables that can be included in the mathematical expression, and the mathematical expression is determined according to the user's operation of the key input unit 11. The CPU 13 detects a variable included in the inputted mathematical expression from among the variable values stored in the variable value memory 145, and determines the inputted mathematical expression and the variable value of the detected variable. Externally output by the display output unit 12.

  Thereby, the numerical formula input by user operation with the scientific calculator 10 can be output with the variable value required for calculation of the said numerical formula. Therefore, it is possible to calculate the mathematical formula with a communication device or a calculation server.

  Note that the CPU 13 sets a variable value of any variable stored in the variable value memory 145 in accordance with a user operation.

  This allows the user to set the variable value.

  Further, the scientific calculator 10 includes a setting data memory 144 that stores a plurality of types of setting data for calculating and displaying mathematical expressions. The CPU 13 selects any of the plurality of types of setting data stored in the setting data memory 144. Or a plurality of them are extracted as setting data necessary for the calculation of the mathematical expression. Then, the input mathematical expression, the variable value of the detected variable, and one or more of the extracted plural types of setting data are externally output by the display output unit 12.

  Thereby, in addition to the mathematical formula and the variable, setting data necessary for calculation of the mathematical formula can be output together.

  Further, when a trigonometric function is included in the inputted mathematical formula, the CPU 13 extracts angle mode setting data relating to the trigonometric function calculation of the mathematical formula as setting data necessary for the calculation of the mathematical formula.

  This makes it possible to calculate a mathematical expression including a trigonometric function with a communication device or a calculation server.

  Further, external output of the input mathematical formula and the detected setting data or variable value can be performed by converting them into a two-dimensional code and displaying them.

  Thereby, it is not necessary to mount a wired or wireless communication function on the scientific calculator 10, and the scientific calculator 10 can be provided at a low cost.

  Further, according to the calculation server 20 having the above-described configuration, the mathematical formula and the variable value of the variable included in the mathematical formula or the setting data necessary for the computation of the mathematical formula are externally output from the scientific calculator 10 which is the mathematical formula processing apparatus. Received by the unit 25, the CPU 21 calculates the mathematical expression based on the received mathematical expression and the variable value of the variable included in the mathematical expression or the setting data necessary for the calculation of the mathematical expression. Is transmitted by the communication unit 25. Further, when the received mathematical formula and the variable value of the variable included in the mathematical formula or the setting data necessary for the calculation of the mathematical formula do not match, the CPU 21 transmits information indicating that they do not match from the communication unit 25. To do. And when the said numerical formula and the variable value of the variable contained in the said numerical formula or the setting data required for the calculation of the said mathematical formula do not match, the corrected variable value or setting data can be received in the said communication part 25. .

  Thereby, it is possible to receive the mathematical expression output by the user operation on the scientific calculator 10 and the variable value of the variable included in the mathematical expression or the setting data necessary for calculating the mathematical expression, and calculate the mathematical expression. Become. In addition, when the formula and the variable value of the variable included in the formula or the setting data necessary for the calculation of the formula do not match, the modified variable value or the setting data can be received.

  Further, the communication unit 25 uses the two-dimensional code to store data including the mathematical expression that is two-dimensionally encoded in the scientific calculator 10 and variable values of variables included in the mathematical expression or setting data necessary for calculation of the mathematical expression. Is received from the camera-equipped communication device E.

  Thereby, it is not necessary to mount the communication function which communicates with the said calculation server 20 in the scientific calculator 10, and the scientific calculator 10 can be provided cheaply.

  In addition, the CPU 21 determines that the received mathematical formula and the received modified variable when the mathematical formula does not match the variable value of the variable included in the mathematical formula or the setting data necessary for the calculation of the mathematical formula. The mathematical expression is calculated based on the value or the setting data, and the calculation result is retransmitted by the communication unit 25.

  Thereby, the corrected calculation result can be provided.

  Note that the external output of the input mathematical formula and the detected setting data or variable value is not limited to the display output by the display output unit 12, but as shown by a broken line in FIG. Of course, the wireless output by 16 may be used. In this case, the camera-equipped communication device E receives the mathematical formula and setting data or variable values output from the outside by a wireless communication unit (not shown), and receives the calculation server 20 via the communication network N. Will be sent to.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.

  As the scientific calculator 10 as a mathematical expression processing device, a so-called graph scientific calculator configured to display a calculation result in a graph is also known. The second embodiment is an example when the present invention is applied to such a graph scientific calculator.

  The configuration itself of the electronic circuit of the graph scientific calculator is the same as that of the scientific calculator 10 of the first embodiment shown in FIG.

  In this graph scientific calculator, as shown in FIG. 12A, the function is input as Y1 = sin (x), Y2 = cos (x), the calculation range is input, and the [QR] key is pressed. Then, as shown in FIG. 12B, in the same manner as in the first embodiment, the address of the calculation server 20, the unique ID of the scientific calculator 10, the function type (for example, function table function), and calculation by function Data (function formula and calculation range), extracted data (for example, angle mode), and others can be QR-coded and displayed on the display output unit 12. The contents of the QR code (QR data) are, for example, as shown in FIG. Here, it is assumed that the angle mode is set to radians (Rad). As a result of the processing of step S204 in the calculation server 20 based on such QR data, the camera-equipped electronic device E displays a table that is the calculation result as shown in FIG. It will be displayed on the ED.

  In the second embodiment, similarly to the graph scientific calculator, the electronic device E with camera can be switched to the graph display. This is realized by adding a process as shown in FIG. 8B between the step S204 and the step S205 in the server process in the calculation server 20.

  That is, following the process of step S204, the CPU 21 determines whether or not a display switching instruction has been received from the communication device E with the camera by the communication unit 25 (step S208). If it is determined that the display switching instruction has not been received, the CPU 21 advances the process to step S205.

  On the other hand, if it is determined that the display switching instruction has been received, the CPU 21 performs processing according to the function type using the function formula and the extracted data after the display switching (step S209). That is, in step S204, since the calculation is performed in the step indicated by the QR data, only a discrete calculation result is obtained, and therefore a graph cannot be displayed. Therefore, recalculation is performed in finer steps to obtain a calculation result for graph display, graph data is generated from the calculation result, and the electronic device E with the camera of the transmission source via the communication network N is transmitted by the communication unit 25. Send to. Thereby, in the electronic device E with a camera which image | photographed QR code displayed and output on the display output part 12 of a graph scientific calculator, the graph data which is this calculation result are received, and as shown in FIG.12 (E), It can be displayed on the display output unit ED.

  Thereafter, the CPU 21 advances the process to the mathematical expression of step S205 and the detected data matching confirmation process.

  In the QR data of FIG. 12C, since the angle mode is radians (Rad) and the setting value of the calculation range is not a multiple of π / 12 (radians), the same processing as in the first embodiment is performed. In step S205N, the correction screen is transmitted to the camera-equipped communication device E, and an alarm display AL as shown in FIG. 13A is displayed on the display output unit ED of the communication device E. A user who has confirmed such an alarm display AL corrects the setting to the correct angle mode on the communication device E with the camera as shown in FIG. In step S205P, the CPU 21 updates the angle mode of the reception QR data memory 222 corresponding to the received setting value in step S205P, and in step S207, the updated QR is updated. A process corresponding to the function type is performed using the data function expression and the extracted data. That is, the CPU 21 performs recalculation to obtain graph data as a calculation result, and the communication unit 25 retransmits the calculation result to the transmission-source electronic device E with the camera via the communication network N. As a result, the camera-equipped electronic device E can receive the retransmitted graph data as the calculation result and display it on the display output unit ED, for example, as shown in FIG. 13C.

  In this example, the table display is set first and the display is switched to the graph display. Conversely, the graph display is set first and the display is switched to the table display. It goes without saying that it is possible.

  Further, as in the first embodiment, the above description has been given by taking as an example the case where the calculation of the functional expression is executed by the calculation server 20, but the function of the calculation server 20 can be realized by the communication device E with a camera, for example, a smartphone. Of course, it may be provided in the form of a simple application.

The methods are all programs that can be executed by a computer, such as a memory card (ROM card, RAM card, etc.), a magnetic disk (floppy (registered trademark) disk, hard disk, etc.), an optical disk (CD-ROM, DVD, etc.), It can be stored and distributed in an external recording medium (M) such as a semiconductor memory.

  Further, each processing method by the calculation server 20 described in each of the embodiments, that is, the server processing shown in the flowchart of FIG. 8A, the server processing shown in the flowchart of FIG. 8B, and the flowchart of FIG. Each method such as mathematical expression and detection data matching confirmation processing is a program that can be executed by a computer, such as a memory card (ROM card, RAM card, etc.), magnetic disk (floppy disk, hard disk, etc.), optical disc (CD-). ROM, DVD, etc.) and a storage medium (23) such as a semiconductor memory can be stored and distributed. Further, the program data for realizing each of the above methods can be transmitted on the communication network N in the form of a program code, and the program data is transmitted to the computer of the electronic device connected to the communication network N as a communication unit. By taking in by (25), the server function described above can also be realized.
