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. 3A, “1, 2, 1, 2” in which the coefficient of each variable of the formula “x + 2y + z = 2” and the values on the right side are sequentially shown as numerical values and corresponds similarly to the formula “3x + 5y + 3z = 5” An example is shown in which "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 in which the transmission data is encoded, and causes the display 12 to display the QR code (steps S12 and S13).

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

Server Behavior
The server 4 executes a QR code using process.
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 follows the QR code utilization program 54a. The process is to be performed.

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

  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 will be.

Thereafter, the CPU 58 repeatedly determines whether or not the calculation mode has been changed in the portable terminal 6 (step S30).
In this process, when the user performs touch operation on the input unit 60 of the portable terminal 6 to change the calculation mode, the CPU 68 of the portable terminal 6 transmits that effect from the communication unit 72 to the server 4 and instructs 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 reextracts template information 54b corresponding to the changed calculation mode from the storage unit 54 (step S31).
Thereafter, the CPU 58 applies the above-specified numerical value as it is to the template information 54b re-extracted as it is without changing it, and converts the constructed calculation formula into another calculation formula (step S32).
In FIG. 3 (b), the calculation mode is changed from the EQN mode to the MATRIX mode or STAT mode, and the numerical value specified above is 1 → for variables a to l of template information for the MATRIX mode or STAT mode. Apply a, 2 → b, 1 → c, 2 → d, 3 → e, 5 → f, 3 → g, 5 → h, 7 → i, 8 → j, 7 → k, 8 → 1 and so on. An example is shown.

  Also in this case, the CPU 58 transmits the converted formula data from the communication unit 59 to the portable terminal 6, and the user can use the converted 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 function calculator 2 side uses the mode code, the input numerical value, and the terminal ID. The QR code is generated, and the server 4 side extracts the template information 54b from the mode code and the terminal ID, and the extracted numerical value is applied to the extracted template information 54b, and corresponds to the calculation mode selected by the scientific calculator 2 Formulas are built.

According to this configuration, the calculation mode is complemented on the side of the server 4 as long as the numerical value is input on the side of the scientific calculator 2, and the mathematical expression of the scientific calculator 2 is realized as it is on the portable terminal 6. Therefore, in the portable terminal 6, in cooperation with the server 4, data of mathematical expression such as equation expression and matrix expression can be created instantly.
Furthermore, since the template information 54b is already prepared on the server 4 side, it is sufficient for the scientific calculator 2 side to simply encode small-size data such as mode code, numerical value and terminal ID into a QR code. Data of mathematical expression can be virtually transmitted to the portable terminal 6 via the server 4.
From the above, the mathematical expression of the scientific calculator 2 can be used as it is in the portable terminal 6 as well.

  In such a case, since the display target of the mathematical expression is switched from the small-sized scientific calculator 2 to the large-sized portable terminal 6, “visually understandable expression” can be provided to the user. Information in the scientific calculator 2 such as “pasting data in an electronic report” can be taken out and used.

  As shown in steps S30 to S32 in FIG. 3B, 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 the change of the calculation mode.
