  FIG. 6 is a flowchart showing received data aggregation processing accompanying server processing of the calculation server 30.

  FIG. 7 is a flowchart showing display control processing of the scientific calculator 10.

  FIG. 8 is a flowchart showing the QR photographing process of the teacher communication device 30.

  FIG. 9 is a diagram showing a display operation of the teacher communication device 20 and the scientific calculator 10 of the student A when the calculation server 30 is used.

  FIG. 10 is a diagram illustrating a display operation of the teacher communication device 20 and the student B scientific calculator 10 when the calculation server 30 is used.

  First, when the CPU 31 of the calculation server 30 receives a communication from the tablet PC with camera or the smartphone with camera as the teacher communication device 20 via the communication network N, the communication unit 35 receives the QR on the tablet PC. It is determined whether or not the barcode content data is received by operation (step S301).

  If it is determined that the barcode content data is not received by the QR operation, the CPU 31 uses the communication unit 35 to transmit the screen data for confirming the processing to be performed (Class ID registration / class registration data display) to the communication network N. To the transmission source tablet PC (step S302). For example, when the tablet PC which is the teacher communication device 20 accesses the calculation server 30 and opens the link of the home page of the calculation server 30 or when the tablet PC accesses the calculation server 30 from a dedicated application, the step 301 is performed. In step S302, it is determined that the barcode content data is not received by the QR operation, and screen data for confirming the processing to be performed in step S302 is transmitted. As a result, the confirmation screen is displayed and output on the display output unit 21 of the teacher communication device 20, and the teacher who is the user selects a process to be performed.

  Therefore, the CPU 31 determines whether or not the registration of ClassID by the operation of this teacher has been received (step S303). If it is determined that the registration of the Class ID has been received, the CPU 31 transmits screen data for confirming the Class ID (group ID) and the mail address to the teacher communication device 20 via the communication network N by the communication unit 35. The data is transmitted to a certain tablet PC (step S304). In the teacher communication device 20 that has received this, a screen for confirming the ClassID (group ID) and the mail address is displayed on the display output unit 21. Then, as shown in FIG. 9A, by inputting the ClassID (group ID) of the class that the teacher is in charge of and the mail address of the tablet PC, and selecting [OK], the CPU 31 can select this user (teacher ) Are received by the communication unit 35 via the communication network N, and registered in the group ID memory 323 of the memory 32 in association with each other (step S305).

  Further, the CPU 31 stores the data of the class table (or group (group) table) of the class in charge input by the user (teacher) and the student (scientific calculator 10) specific to each seat (or group (group)). When the ID correspondence data is received, it is registered in the registration data memory 322 of the memory 32 in association with the corresponding ClassID as described above (step S306).

  Then, a class-specific reception data area 322A dedicated to the class is created in the registration data memory 322 of the memory 32 (step S307). Thereafter, the CPU 31 returns the process to step S301.

  As a result, the teacher's e-mail address is registered in the group ID memory 323 of the calculation server 30 in association with the class ID (group ID) of the teacher's class by the teacher communication device (tablet PC) 20. In addition, the registered data memory 322 is associated with the class ID (group ID) of the corresponding class for each class (322A...), And the unique ID of the student (scientific calculator 10) corresponds to each seat (or each group). The attached seating chart (or group (group) chart) data will be registered.

  Before continuing the description of the server process, the display control function of the scientific calculator 10 will be described according to the flowchart of the display control process of FIG.

  For example, in the scientific calculator 10A used by the student A belonging to ClassID (group ID): ABC123, the CPU 13 determines whether or not the operation of the key input unit 11 is an execution operation of the statistical function, that is, according to the [MODE] key operation. It is determined whether or not it is an execution operation of a statistical calculation function among the functions displayed as a list (step S101). Here, if it is determined that the operation is not an execution operation of the statistical function, the CPU 13 advances the processing to other processing.

  On the other hand, when it is determined that the operation is an execution operation of the statistical function, as shown in FIG. 9B, the CPU 13 displays the calculation types (1) displayed as a list on the display output unit 12 as the statistical mode selection screen Gs. Among the variable statistics / 2-variable statistics; linear regression / logarithmic regression / e exponential regression / ab exponential regression / power regression / reciprocal regression / secondary regression), designation of a calculation type by a user operation of the key input unit 11 is accepted (step S102). ). Further, the CPU 13 accepts input of calculation target data X (and Y) by a user operation of the key input unit 11 (step S103).

  Here, “2” (two-variable statistics; linear regression) is designated on the statistical mode selection screen Gs, and the table data input screen Gi displayed on the display output unit 12 as shown in FIG. A case where table data of two variables X and Y is input will be described. The input table data X and Y are registered in the input data area 143 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 S104). If it is determined that the [QR] key has not been pressed, the process proceeds to step S106 described later.

  On the other hand, when it is determined that the [QR] key is pressed, the CPU 13 executes the unique ID of the scientific calculator 10A stored in the unique ID 142 of the memory 14 and the execution data stored in the input data area 143. Two-dimensional code image of function type (here, statistical function and calculation type), function-specific calculation target data (table data X, Y and statistical calculation type (two-variable statistics; linear regression)), setting information, etc. (QR code) is converted into a two-dimensional code image (QR code) Q and output to the display output unit 12 as shown in FIG. 9D (step S105).

  The setting information is not particularly shown in the flowchart, but is set according to the [SHIFT] + [MODE] (= [SETUP]) key operation of the key input unit 11 and stored in the input data area 143. As the setting information, for example, angle mode (deg (degree) mode / rad (radian) mode / gra (grad) mode), rounding mode (norm (exponent display) mode / Fix (fixed number of decimal places) mode) / Sci (significant digit designation) mode), display mode (LineIO (single line display) mode / MthIO (textbook display) mode) and the like.

  On the other hand, if the CPU 13 determines that the statistical calculation processing has been instructed, the statistical calculation processing based on the data registered in the input data area 143, that is, one-variable statistical calculation or two-variable statistical calculation is designated by the user operation. The process is executed according to the type (step S107). Then, the result data of the statistical calculation is displayed and output to the display output unit 12 (step S108).

  For example, in the class ID (group ID): Student B scientific calculator 10B belonging to the same class as the student A, the calculation type “2” (two-variable statistics; linear regression) is specified on the statistical mode selection screen Gs. Then, as shown in FIG. 10A, the table data of the two variables X and Y is input on the table data input screen Gi (steps S102 and S103).

  When a statistical calculation process is instructed (step S106), the CPU 13 executes a statistical calculation (two-variable statistical calculation; linear regression) based on the input table data X and Y (step S107). As shown in FIG. 10B, the statistical calculation result data is displayed on the display output unit 12 as a calculation result screen Gcl (step S108).

  Thereafter, when the CPU 13 determines that the [QR] key of the key input unit 11, that is, the [SHIFT] + [OPTN] key is pressed (step S 109), the CPU 13 stores the unique ID 142 in the memory 14. A unique ID of the scientific calculator 10B, a function type (in this case, a statistical function and a calculation type) of an execution function stored in the input data area 143, a calculation result data, setting information, etc. Then, as shown in FIG. 10C, a two-dimensional code image (QR code) Q is displayed and output to the display output unit 12 (step S110).

  Thereafter, the CPU 13 determines whether or not there is re-input of data (step S111). 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 102.

  As described above, in the scientific calculators 10A, 10B,... Of the students A, B,..., The corresponding two-dimensional code images (QR codes) Q are displayed on the display output unit 12 by the display control process described above.

  Here, the QR photographing transmission function of the teacher communication device (tablet PC) 20 will be described with reference to the flowchart of the QR photographing processing of FIG.

  When the tablet PC with camera as the teacher communication device 20 takes an image of the two-dimensional code image (QR code) Q as shown in FIGS. 9E and 10D, the CPU 22 The barcode content data that is the content of the dimension code image (QR code) is analyzed to obtain the barcode content data (step S201).

  Then, the CPU 22 determines whether or not the acquired barcode content data matches the format of the barcode content data by the display control process of the scientific calculator 10 (step S202).

  If it is determined that the acquired barcode content data matches the format of the barcode content data by the scientific calculator 10, the analyzed barcode content data and the class of charge stored in the memory 23 are stored. The group ID (Class ID) 227 is transmitted to the calculation server 30 via the communication network N (step S203). The HP address 225 of the calculation server 30 for that purpose is known to the teacher in advance, and the teacher operates the teacher's own communication device 20 to input it and register it in the memory 23.

  Here, in the case where the barcode content data is a two-dimensional code image (QR code) Q taken from the scientific calculator 10A of the student A, the unique ID, function type (statistical function and calculation type) of the scientific calculator 10A ), Calculation target data by function (table data X, Y and type of statistical calculation (two-variable statistics; linear regression)), setting information, and other data, two-dimensional code taken from the scientific calculator 10B of student B In the case of the image (QR code) Q, it is the unique ID, function type (statistical function and calculation type), calculation result data, setting information, and other data of the scientific calculator 10B.

  When the barcode content data transmitted from the teacher communication device 20 via the communication network N is received by the communication unit 35 in the calculation server 30, the CPU 31 of the calculation server 30 displays the barcode data by the QR operation in step S301. It is determined that the code content data is received. In this case, the CPU 31 receives the received barcode content data, that is, in the case of the scientific calculator 10A, the unique ID of the scientific calculator 10A: xxx1, the ClassID to which the student A belongs: ABC123, the function type (statistical function and calculation type) ), Function-specific calculation target data (table data X, Y and type of statistical calculation (two-variable statistics; linear regression)), setting information, etc., in the case of the scientific calculator 10B, the unique ID of the scientific calculator 10B: xxx2, ClassID to which Student B belongs: ABC123, function type (statistical function and calculation type), calculation result data, setting information, and the like are stored in a work area (not shown) for storing received data provided in the memory 32. (Step S308).

  Thereafter, the ClassID in the stored barcode content data is confirmed, and it is determined whether or not it matches the ClassID registered in the group ID memory 323 (step S309). If it is determined that the Class ID does not match the registered one, the CPU 31 returns the process to step S301.

  On the other hand, when it is determined that the ClassID (group ID) in the stored barcode content data matches the registered one, the CPU 31 uses the stored barcode content data as class data as the registration data memory 322. Are registered in the class-specific data area 322A corresponding to the registered ClassID (step S310).

  Thereby, in the class-specific data area 322A corresponding to the registered ClassID: ABC123, together with the data of the seating chart (or group (group) table) of the corresponding class registered by the teacher communication device (tablet PC) 20, The unique ID and statistical data (calculation target data) of the student A and the unique ID and statistical data (calculation result data) of the student B are registered.

  After this, the tablet PC which is the teacher communication device 20 accesses the calculation server 30 and opens the link of the home page of the calculation server 30 or accesses the calculation server 30 from the dedicated application on the tablet PC and registers the class. When the data display is selected, the CPU 31 of the calculation server 30 determines that the registration of the Class ID has not been received in step S303 (steps S301 to S303).

  In this case, the CPU 31 receives the group ID (Class ID) 227 and the mail address 224 registered in the communication device 20 automatically transmitted from the teacher communication device 20 (step S311).

  Then, the CPU 31 determines whether or not the group ID (ClassID) 227 and the mail address 224 received from the teacher communication device 20 are the ClassID and mail address of the teacher registered in the group ID memory 323 (step). S312).

  When it is determined that the group ID (ClassID) 227 and the mail address 224 received from the teacher communication device 20 are the registered ClassID and mail address, the process proceeds to the received data aggregation process in FIG. 6 (step S313). .

  In this received data aggregation process, the CPU 31 is a student who is the first received data registered from the class-specific data area 322A corresponding to the registered group ID (ClassID: ABC123) received from the teacher communication device 20. Statistical data associated with A's unique ID: xxxx1 is read (step S1), and it is determined whether or not the received data (statistical data) is statistical mode table data (step S2).

  Here, when it is determined that the received data (statistical data) associated with the student A's unique ID: xxx1 is statistical mode table data, the statistical calculation table data (see FIG. 9C). ), The statistical calculation (two-variable statistics; linear regression) specified in the function-specific calculation target data (table data X, Y and the type of statistical calculation) is performed, and the plot points of the table data X, Y A graph image composed of a graph of linear regression is created (step S3).

  Then, it is determined whether or not a seating chart (or group chart) is registered in the class-specific data area 322A corresponding to the registered group ID (ClassID: ABC123) (step S6).

  Here, the case where the seating chart (or group chart) is not registered will be described first.

  When the seating chart (or group chart) is not registered, the received data (statistical data: chart data) of the student A and the graph image data created from the statistical data are arranged in order from left to right. Image data (see FIG. 11) is created (step S10).

  Thereafter, when the CPU 31 determines that there is next received data in the class-specific data area 322A corresponding to the group ID (ClassID: ABC123) (step S11), the student B corresponding to the group ID (ClassID: ABC123). Statistical data associated with the unique ID: xxxx2 is read (step S12).

  When it is determined that the statistical data of the student B is the calculation result data in the statistical mode (step S4), the statistical calculation designated by the function type is performed on the calculation result data (see FIG. 10B). (Two variable statistics; linear regression) is executed, and a graph image consisting only of a linear regression graph of the calculation result data is created (step S5).
