<3. Processing action>
Next, the processing operation of the electronic book reference content display system according to the present embodiment will be described with reference to the sequence diagram of FIG. When the user activates the electronic book application, the book data can be displayed on the display unit 10f according to the user's instruction via the instruction input unit 10d. In this state, the user designates a range of book data to be displayed. Then, the display range determination means 11 determines the range of the book data to be displayed based on the instruction input content by the instruction input unit 10d (step S11). Specifically, the user designates a page to be displayed, and the display range determination unit 11 determines book data corresponding to the designated page as the display range. Actually, the CPU 10a reads the book data corresponding to the designated page into an area secured as a display memory in the RAM 10b, and the read book data is determined as the display range. At this time, if a display memory is prepared separately from the RAM 10b, the book data is read into the display memory.

  Then, the reference target specifying unit 12 specifies the reference target included in the display range determined by the display range determining unit 11 (step S12). Specifically, the CPU 10a that implements the reference target specifying unit 12 specifies the reference target by acquiring the target ID (ID for specifying the reference target) attached to the book data read into the display memory. When there are a plurality of target IDs, a plurality of target IDs are acquired.

  On the other hand, the CPU 10a displays the book data read into the display memory on the display unit 10f. Thereby, the book data is displayed on the display unit 10f in a state as shown in FIG. The CPU 10a interprets the book data described in HTML and displays it on the display unit 10f.

In FIG. 8A, each character string “beetle”, “stag beetle”, and “bee” that is a reference target is surrounded by a frame to indicate that display processing is performed. The display processing can be performed in various forms. For example, when the HTML tag shown in FIG. 4 is attached, the display processing is displayed in blue (color = blue).

  Next, the target identification information transmitting unit 13 transmits the target ID acquired by the reference target specifying unit 12 to the data management server 20 (step S13). In the example of FIG. 8, three target IDs “10010001”, “10010002”, and “10010003” respectively corresponding to “beetle”, “stag beetle”, and “bee” are transmitted.

  In the data management server 20, the communication unit 20g receives the target ID transmitted from the portable terminal 10. Then, the viewpoint list acquisition unit 21 refers to the viewpoint storage unit D2 with the received target ID, and acquires a corresponding viewpoint list (step S14). When there are a plurality of target IDs, a plurality of viewpoint lists are acquired corresponding to the plurality of target IDs. In this example, the viewpoint list corresponding to the target IDs “10010001”, “10010002”, and “10010003” shown in FIG. 5 is acquired. Subsequently, the viewpoint list transmission unit 22 transmits the acquired viewpoint list to the portable terminal 10 (step S15).

  In the portable terminal 10, the communication unit 10 g receives the viewpoint list transmitted from the data management server 20. Then, the viewpoint list display means 14 displays the received viewpoint list (step S16). Actually, the CPU 10a displays the received viewpoint list on the display unit 10f. FIG. 8B shows a screen state when the viewpoint list is displayed. When the viewpoint list is displayed, a predetermined area on the left side of the screen is secured as the viewpoint list display area. At this time, if the number of viewpoint lists is large and all of them do not fit in the viewpoint list display area, a scrollable state is set. In the example of FIG. 8B, since there are three viewpoint lists that do not fit in the viewpoint list display area, two viewpoint lists of “beetle” and “stag beetle” are displayed. For the viewpoint list of “bee”, A “▽” mark indicates that scrolling is possible downward. Therefore, the viewpoint list of “bee” is displayed by scrolling downward. When the user selects one viewpoint from the displayed viewpoint list, the viewpoint identification information transmitting means recognizes the selected viewpoint, and transmits the reference content request together with the viewpoint ID for identifying the selected viewpoint. It transmits to the management server 20 (step S17).

  In the data management server 20, the communication unit 20 g receives the reference content request and the viewpoint ID transmitted from the portable terminal 10. Then, the reference content acquisition unit 23 refers to the reference content storage unit D3 with the received viewpoint ID, and acquires the corresponding reference content (step S18). Specifically, as illustrated in FIG. 6, a reference content path corresponding to a viewpoint ID (a combination of a target ID and a viewpoint word / phrase) is acquired, and the reference content path indicates the reference content storage unit D3. In this case, the reference content is acquired using the reference content path. If there are a plurality of reference contents corresponding to the viewpoint ID, a plurality of reference contents are acquired. Subsequently, the reference content transmission unit 24 transmits the reference content acquired by the reference content acquisition unit 23 to the portable terminal 10 (step S19).

  In the portable terminal 10, the communication unit 10g receives the reference content transmitted from the data management server 20. Then, the reference content display means 16 displays the received reference content (step S20). Specifically, the CPU 10a displays the received reference content on the display unit 10f. When a plurality of reference contents are received, the plurality of reference contents are displayed in a predetermined format.

  In the above step S18, when there is no reference content corresponding to the viewpoint ID in the reference content storage unit D3 and the URL of the reference content is recorded, the reference content transmission unit 24 stores the URL in the portable terminal 10 Send to. In the portable terminal 10, when the communication unit 10 g receives the URL of the reference content, the URL is used to access a site where the reference content exists and acquire the reference content. Then, the reference content display unit 16 displays the acquired reference content.

  FIG. 9 is a diagram showing a state in which the reference content is displayed on the screen by the reference content display unit 16. As shown in FIG. 9, the reference content is displayed on the book data display area so as to overlap the book data. When a plurality of reference contents are acquired, one is displayed in the center, and the other reference contents are reduced and displayed at a predetermined ratio. If it does not fit in the book data display area even if it is reduced, it is displayed in a state where a part is hidden behind the reference content displayed in the center. Marks indicating left and right are displayed on both sides of the reference content displayed in the center, and when this mark is operated, the CPU 10a performs a process of replacing the reference content displayed in the center with other reference content.
