[Operation of information processing system]
[Function of scientific calculator]
The scientific calculator 2 executes a QR code generation process.
The QR code generation process is executed by cooperation of the QR code generation program 44a and the CPU 48 as a result of the QR code generation program 44a being read from the storage unit 44 and expanded in the RAM 46. The CPU 48 executes the QR code generation program 44a according to the QR code generation program 44a. The said process is performed.

As shown in FIG. 3A, the user operates the MODE key 20 and the cursor key 28 to select one of a plurality of calculation mode selections, and operates the numeric key 30 to input a numerical value. Then, the CPU 48 accepts calculation mode selection and numerical value input (step S10).
FIG. 3A shows an example in which the EQN (equation calculation) mode is selected as the calculation mode, and simultaneous equations including the formulas “x + 2y + z = 2”, “3x + 5y + 3z = 5”, and “7x + 8y + 7z = 8” are input. Yes.
Thereafter, the CPU 48 generates transmission data including the mode code corresponding to the selected calculation mode, the input numerical value, and the terminal ID of the scientific calculator 2 (step S11).
In FIG. 3 (a), as numerical values, "1, 2, 1, 2" sequentially showing the coefficient of each variable of the numerical formula "x + 2y + z = 2" and the numerical value on the right side correspond to the numerical formula "3x + 5y + 3z = 5". In this example, “3, 5, 3, 5” and “7, 8, 7, 8” corresponding to the mathematical expression “7x + 8y + 7z = 8” are input.
Thereafter, the CPU 48 generates a QR code obtained by encoding the transmission data and displays it on the display 12 (steps S12 and S13).

[Operation of mobile terminal]
When the user images the QR code of the scientific calculator 2 with the imaging unit 70, the CPU 68 decodes the QR code, and the CPU 68 transmits the decoded transmission data from the communication unit 72 to the server 4.

[Server Operation]
In the server 4, a QR code use process is executed.
The QR code utilization process is executed by the cooperation of the QR code utilization program 54a and the CPU 58 as a result of the QR code utilization program 54a being read from the storage unit 54 and expanded in the RAM 56. The CPU 58 executes the QR code utilization program 54a according to the QR code utilization program 54a. The said process is performed.

As shown in FIG. 3B, the CPU 58 receives the data for transmission via the communication unit 59 and analyzes it (steps S20 and S21).
Thereafter, the CPU 58 specifies the mode code, numerical value, and terminal ID included in the transmission data based on the analysis result, and extracts the template information 54b corresponding to the mode code and terminal ID from the storage unit 54 (step S22). ).
Here, in particular, the mode code included in the transmission data is referred to, and the template information 54b corresponding to the mode code is specified and extracted.
In FIG. 3B, the EQN mode mode included in the transmission data is selected from the template information for the EQN mode, the template information for the MATRIX (matrix calculation) mode, the template information for the STAT (statistical calculation) mode, and the like. An example is shown in which template information for EQN mode corresponding to a code is extracted.
Thereafter, the CPU 58 applies the specified numerical value to the extracted template information 54b, and constructs the original calculation formula corresponding to the calculation mode selected by the scientific calculator 2 (steps S23 and S24).
In FIG. 3B, the numerical values specified for the coefficients a to l of the template information for the EQN mode of the simultaneous equations consisting of the mathematical expressions “ax + by + cz = d”, “ex + fy + gz = h”, “ix + jy + kz = l” 1 → a, 2 → b, 1 → c, 2 → d, 3 → e, 5 → f, 3 → g, 5 → h, 7 → i, 8 → j, 7 → k, 8 → l, etc. A fitted example is shown.

  Thereafter, the CPU 58 transmits the constructed calculation formula data from the communication unit 59 to the portable terminal 6, and the user can use (execute) the original calculation formula expressed by the scientific calculator 2 as it is on the portable terminal 6. It becomes like this.

Thereafter, the CPU 58 repeatedly determines whether or not the calculation mode has been changed on the mobile terminal 6 (step S30).
In this process, when the user touches the input unit 60 of the portable terminal 6 and changes the calculation mode, the CPU 68 of the portable terminal 6 transmits a message to that effect from the communication unit 72 to the server 4 to instruct the change of the calculation mode. The CPU 58 of the server 4 receives this via the communication unit 59 and determines whether or not the calculation mode has been changed.
When the calculation mode is changed, the CPU 58 re-extracts the template information 54b corresponding to the changed calculation mode from the storage unit 54 (step S31).
Thereafter, the CPU 58 applies the previously specified numerical value as it is to the re-extracted template information 54b, and converts the constructed calculation formula into another calculation formula (step S32).
In FIG. 3B, the calculation mode is changed from the EQN mode to the MATRIX mode or the STAT mode, and the numerical value specified previously for the variables a to l of the template information for the MATRIX mode or the STAT mode is 1 → a, 2 → b, 1 → c, 2 → d, 3 → e, 5 → f, 3 → g, 5 → h, 7 → i, 8 → j, 7 → k, 8 → l An example is given.

  In such a case, the CPU 58 transmits the converted calculation formula data from the communication unit 59 to the portable terminal 6, and the user can use the converted calculation formula as it is on the portable terminal 6.

  In the above embodiment, as shown in steps S10 to S13 in FIG. 3A and steps S20 to S24 in FIG. 3B, the scientific calculator 2 side uses the mode code, the input numerical value, and the terminal ID. A QR code is generated, and template information 54b is extracted from the mode code and terminal ID on the server 4 side, and a numerical value input to the extracted template information 54b is applied to correspond to the calculation mode selected by the scientific calculator 2. The calculation formula to be built is constructed.

According to this configuration, as long as a numerical value is input on the scientific calculator 2 side, the calculation mode is complemented on the server 4 side, and the mathematical expression of the scientific calculator 2 is realized as it is on the portable terminal 6. Therefore, the portable terminal 6 can instantaneously create mathematical expression data such as equation expression and matrix expression in cooperation with the server 4.
Furthermore, since the template information 54b has already been prepared on the server 4 side, the small amount of data such as the mode code, the numerical value, and the terminal ID need only be encoded into the QR code on the scientific calculator 2 side. The mathematical expression data can also be virtually transmitted to the mobile terminal 6 via the server 4.
From the above, the mathematical expression of the scientific calculator 2 can be used in the portable terminal 6 as it is.

  In such a case, since the display object of the mathematical expression is switched from the small scientific calculator 2 to the large portable terminal 6, it is possible to provide a “visually easy-to-understand expression” to the user. Information in the scientific calculator 2, such as “pasting data into an electronic report”, can be used outside.

  As shown in steps S30 to S32 of FIG. 3 (b), only the mathematical expression can be converted on the server 4 side while the numerical value input on the scientific calculator 2 side is fixed. It is possible to flexibly cope with changes in the calculation mode.
