Further, if the touch sensor is traced with the finger in the order of 15e → 15d, the item selected on the setting menu is determined, and if it is traced in reverse, the determination is canceled (FIG. 5B). Further, if the touch sensor is traced with a finger in the order of 15g → 15h, the page is turned in the forward direction of the content selected on the content selection menu, and if it is traced in the reverse direction, the page is turned in the reverse direction ( FIG. 5 (c)). Further, when the touch sensor is traced in the order of 15b → 15a, switching to right hand holding is performed (FIG. 5 (d)).

  FIG. 6 is a block diagram showing a configuration of the electronic display device 10. The device 10 includes a display unit 12, a touch sensor 15 that functions as an operation unit, a storage unit 17 that stores content information, a temporary storage unit 18 that includes a read data storage area 20 and a management data storage area 19, and a display. And a control unit 16 for controlling.

  The storage unit 17 is a storage medium such as a memory card attached to the apparatus, and stores a large number of browsing contents together with bibliographic data, a cover thumbnail, and the like. The storage medium is generally removable and is provided with a copyright protection function, and the content cannot be copied to another recording medium, but the type is not particularly limited.

  The temporary storage unit 18 includes a volatile memory, and the read data storage area 20 reads and stores pages displayed on the display unit 12 of the content to be browsed and pages before and after the page from the storage unit 17. .

  The management data storage area 19 of the temporary storage unit 18 stores a management table created using bibliographic data read from the storage unit 17 as shown in FIG. In this management table, the content name transcribed from the bibliographic data, the total number of pages of each content, the storage position (address) of each content on the storage unit 17 and the like are described, and recently selected and browsed. When the content is flagged and the content is browsed, the last display page read is described as the read page. The read page of the content that has not been browsed remains at the initial value of 1.

  The control unit 16 holds two programs, “content selection program” and “content display program”, and input information from the lines 15 b, 15 c, 15 e, 15 f, and 15 h (vertical bar lines) of the touch sensor 15. The content selection program is started based on the above, and for content display based on the input information from the 15a and 15b lines for the right-handed hand, and the 15g and 15h lines (upper horizontal line) for the left-handed hand Start the program. Then, the content selection and content display display operations defined in association with the input information of the touch sensor 15 in each program are controlled.

  Next, the display operation of the electronic display device 10 will be described.

  When the power of the apparatus 10 is turned on, the control unit 16 first activates a content selection program, reads bibliographic data of each content from the storage unit 17, and stores it in the management data storage area 19 of the temporary storage unit 18. A management table (FIG. 7) is created. In addition, using the bibliographic data, a content selection menu is displayed on the display unit 12, and display control for right-handed holding that is initially set is started. In addition, as shown in FIG.4 (d), when there exists input from 15g following 15h of the touch sensor 15, the time in the meantime is measured with a clock (not shown), and measurement time was preset. When the input information is shorter than the threshold, the input information is identified as valid, and the display control is switched to left-handed display control (the following description will be made with respect to the right-handed state).

  In the content selection menu, as shown in FIG. 8, bibliographic data of a predetermined number (here, 5) of content is displayed side by side. Among them, the bibliographic data of the selected content is displayed in a wide frame at the center of the screen. The thumbnail of the cover of the content is displayed in the frame. The control unit 16 treats the content in the order initially set by the content selection program at the beginning of display as the selected state.

  As shown in FIG. 4A, when there is an input in this order from 15b, 15c, 15e of the touch sensor 15, the control unit 16 measures the time between them, and the measurement time is preset. When the input information is shorter than the threshold, the input information is identified as valid, and the content one level lower than the currently selected content is set in the selected state. Then, the frame for the content is displayed widely in the center of the screen, the thumbnail of the cover of the content is read from the storage unit 17 and displayed in the frame. Also, the bibliographic data located at the top of the content selection menu is removed from the screen, and the bibliographic data newly read from the management table is added to the bottom of the screen.

  Further, when there is an input in the reverse order from 15b, 15c, 15e of the touch sensor 15, processing for newly setting the content one level higher than the content currently selected to the selected state is performed.

  The user updates the selected content one after another by tracing the vertical bar line of the E-shaped operation unit 14 with his / her thumb, and the control unit 16 performs the above-mentioned every time there is input information from the touch sensor of this vertical bar line. Repeat the operation.

  When a predetermined operation for displaying the setting menu is performed from the E-shaped operation unit 14, the setting menu is displayed so as to be superimposed on the content selection menu as shown in FIG. The operation of selecting a setting item from this setting menu is performed by tracing the vertical bar line of the E-shaped operation unit 14, and the determination / cancellation is performed using the middle horizontal bar line (touch sensors 15 d and 15 e of the E-shaped operation unit 14). ), But detailed description thereof is omitted.

  As shown in FIG. 4C, when there is an input from 15b following 15a of the touch sensor 15, the control unit 16 validates this input information when the measurement time is shorter than a preset threshold value. After identifying and flagging the position of the content currently selected in the management table (FIG. 7) stored in the management data storage area 19 of the temporary storage unit 18, the content selection program being activated is terminated. Then, the content display program is started.

  The control unit 16 refers to the management table (FIG. 7) based on the content display program, and acquires data of already read pages of the content to which the flag is attached. Then, the page corresponding to the read page of the content and the previous and subsequent pages are read from the storage unit 17 and stored in the read data storage area 20 of the temporary storage unit 18, and the read page is displayed on the display unit 12. The page corresponding to is displayed.

  Further, as shown in FIG. 4 (c), when there is an input from 15b again after 15a of the touch sensor 15, the control unit 16 then has a measurement time shorter than a preset threshold value. The input information is identified as valid, and the page displayed on the display unit 12 is switched to the next page.

  At this time, the control unit 16 uses the image data of the currently displayed page and the next page stored in the read data storage area 20 of the temporary storage unit 18, as shown in FIG. 10B or FIG. Execute page turning with the display method shown in.

  In the method of FIG. 10B, when switching from the first page to the second page of FIG. 10A, the first and second pages connected in the spread state slide to reach the second page. As described above, a composite image in which a part of the first page and a part of the second page are combined, and a composite image in which the part of the first page is reduced and the part of the second page is increased, After sequentially displaying these composite images, the second page is finally displayed.

  Also, in the method of FIG. 10C, a composite image in which a part of the second page overlaps the first page is displayed, and the display is successively performed with a plurality of composite images in which the overlap of the second page is gradually increased. And the image of the second page is finally displayed.

  When the next page is displayed on the display unit 12, the control unit 16 reads the next page from the storage unit 17 and stores it in the read data storage area 20 of the temporary storage unit 18. The pages other than are deleted from the read data storage area 20.

  Whenever there is an input from 15b following 15a of the touch sensor 15, the control unit 16 repeats the page turning to the next page in the above-described procedure. Further, when there is an input from 15a following 15b of the touch sensor 15, the control unit 16 performs page turning to the previous page in the same procedure.

  In addition, when there is an input from 15b following 15a of the touch sensor 15 and the input from 15b continues thereafter, the control unit 16 measures the duration with a clock (not shown). Then, when the measurement time exceeds a preset time m1, the “high speed mode” in which page turning is continuously performed is executed.

  In the case of the high-speed mode, the number of composite images inserted in the middle of each page turning is set smaller than the page turning for each page. Also in this case, the control unit 16 sequentially reads the next page from the storage unit 17 and stores it in the read data storage area 20 of the temporary storage unit 18 so as to be in time for successive page turning. Further, when the input from the touch sensor 15b is stopped, the page turning operation is stopped when the page turning in the middle of execution is completed.

  Further, as shown in FIG. 4 (a), when there is an input in this order from 15b, 15c, 15e of the touch sensor 15, the control unit 16, when the measurement time between them is shorter than a preset threshold value, This input information is identified as valid, and the finally displayed page is entered in the read page column of the content of the management table (FIG. 7) stored in the management data storage area 19 of the temporary storage unit 18 and started. The content display program is terminated and the content selection program is started.

  Then, the control unit 16 refers to the management table (FIG. 7) based on the content selection program and displays a content selection menu in which the content one level lower than the flagged content is set to the selected state. At this time, if the input order of the touch sensor 15 is 15e → 15c → 15b, a content selection menu in which the content one level higher than the flagged content is set to the selected state is displayed.

  As described above, in the electronic display device 10, in order to select content, an operation of tracing the vertical bar line of the E-shaped operation unit 14 with the thumb is performed, and accordingly, the cover pages of the content are sequentially displayed. When an operation of tracing the upper horizontal bar line of the E-shaped operation unit 14 is performed in order to browse the content on which the cover is displayed, the page read last time for the content is displayed. When reading the content for the first time, the first page is displayed. The page feed of the content being browsed is performed by an operation of tracing the upper horizontal bar line of the E-shaped operation unit 14, and if the upper horizontal bar line is continuously touched after tracing, continuous page feed is performed. Further, when the user traces the vertical bar line of the E-shaped operation unit 14 with the thumb during browsing, the cover of the next content is displayed.

  In this figure, each displayable content is shown in a line in the vertical direction (L direction). The covers of the contents A, B, and C are arranged in a line, and the pages of the contents are expanded horizontally (W direction). A page with a negative value located on the left side of the cover is a read page, page 0 represents the final next page, and pages arranged on the right represent unread pages.

  The operation of tracing the vertical bar line of the E-shaped operation unit 14 with the thumb corresponds to the operation of selecting the cover of each content. If the upper horizontal bar line of the E-shaped operation unit 14 is traced with the cover of the content B selected, the final display page of the content B is displayed (1). Further, when the upper horizontal bar line of the E-shaped operation unit 14 is traced, page feed in the content B is performed (2). If the user stops browsing the page of content B and again traces the vertical line of the E-shaped operation unit 14 with his thumb, the cover of content C is displayed when the vertical line is traced downward. When the bar line is traced upward, the cover of content A is displayed (3).

  Further, as shown in FIG. 12, when the vertical bar line of the E-shaped operation unit 14 is traced, the cover of the initially displayed content A is switched to the cover of the content B (1). When the bar line is traced, the last display page of the content B is displayed (2). Each time the upper horizontal bar line is traced, page feed is performed one page at a time (3). Page feed is performed (4). When the upper horizontal bar line is traced in the reverse direction, page feed in the reverse direction is performed. When the upper horizontal bar line is touched as it is, continuous page feed in the reverse direction is performed.

  When the page browsing of the content B is stopped and the vertical bar line of the E-shaped operation unit 14 is traced downward, the cover of the content C is displayed (5), and when the vertical bar line is traced further downward, the cover of the content D is displayed. Is displayed (6), and when the upper horizontal line of the E-shaped operation unit 14 is traced, the final display page of the content D is displayed (7).

  As described above, this electronic display device can select a content and send a page of the selected content simply by grasping the grip portion of the housing with a hand and tracing the E-shaped operation portion with the finger of the hand. It is extremely easy to operate. Further, when the content selection operation is switched to the content browsing operation, the final display page of the selected content is displayed, so that the continuation of reading can be read efficiently.
