In the non-display detection area 14b, touch panel type operation buttons 14c used for displaying various menus are formed.

As shown in FIG. 2, the tablet terminal 10 includes a CPU 16, a memory 17, a communication unit (electronic book acquisition unit) 18, a storage (storage unit) 19, a display control unit 20, and the like in addition to the display input unit 12 described above. Is provided.

The CPU 16 comprehensively controls each unit of the tablet terminal 10 according to various programs and data read from the memory 17 and the storage 19 based on various operation signals input from the input unit 14. The ROM area of the memory 17 stores the control program and data described above, and the RAM area functions as a work memory for the CPU 16 to execute processing and as a temporary storage destination for various data.

Further, the CPU 16 detects a gesture operation on the display detection area 14a, and executes a function set in advance according to the gesture operation, such as a page feed operation or a page return operation. Note that the gesture operation is not a conventional simple touch operation, but draws a trajectory with at least one position from a plurality of positions by drawing a trajectory with a finger or the like, or simultaneously specifying a plurality of positions. Means an operation.

The communication unit 18 communicates with a server 22 (for example, an electronic book providing server) on the Internet via, for example, a mobile communication network, and transmits and receives various data. The communication unit 18 transmits a distribution request for the electronic comic file 23 to the server 22. In addition, the communication unit 18 receives the electronic comic file 23 transmitted from the server 22 in response to the distribution request for the electronic comic file 23. Instead of acquiring the electronic comic file 23 from the server 22, the electronic comic file 23 may be acquired using a recording medium that is detachable from the tablet terminal 10 such as a memory card.

As the storage 19, a computer-readable non-transitory recording medium such as a hard disk or a nonvolatile memory is used. The storage 19 stores an electronic comic file 23 acquired from the server 22 and a display program (electronic book display program) 24 used for acquisition / display processing of the electronic comic file 23. A recording medium such as a memory card may be used as the storage 19.

The search tag information 29 is information used for searching the electronic comic file 23 and includes information such as a title, an author, a publisher (copyright owner), and the total number of pages.

The page progress information 30 is information indicating the page progress direction of the electronic comic. For example, electronic comics published in Japan (including electronic publishing) often have a page progression direction to the left corresponding to a comic book in Japan that is bound right. In addition, electronic comics published in foreign countries often have a page progression direction to the right corresponding to a comic book that is bound left.

The display program 24 is a program for causing the tablet terminal 10 to function as the electronic book display device of the present invention. When the CPU 16 or the display control unit 20 executes the display program 24, each process of obtaining and displaying the electronic comic file 23 is executed.

The display control unit 20 controls the display of the electronic comic on the display unit 13 according to the display program 24. In the present embodiment, the display control unit 20 is provided separately from the CPU 16. However, for example, the CPU 16 may function as a display control unit.
