PROBLEM TO BE SOLVED: To allow calculation object data for each information display device (for example, a scientific calculator) to be output as integration result data of a result integrated per group including each information display device.SOLUTION: A communication apparatus 20 with a camera of each student photographs a two-dimensional code image about which a scientific calculator 10 of the student has input calculation object data and a display output unit 21 has displayed a two-dimensional code image of the calculation object data, and transmits data obtained by analyzing the image to a calculation server 30. The calculation server 30 has an exclusive data area per group ID, transmits an input request for a group ID to the communication apparatus 20 of the data transmission source, and determines an exclusive data area per group ID corresponding to the received group ID. The calculation server 30 registers the calculation object data received from the communication apparatus 20 with the determined data area per group ID, integrates a plurality of pieces of calculation object data registered per group as image data, and transmits the plurality of pieces of calculation object data to the data transmission source communication apparatus 20.SELECTED DRAWING: Figure 1 |
