The opening / closing angle θ can be adjusted in a range from approximately 0 degrees to over 180 degrees.

  As illustrated in FIG. 2, the mobile terminal 10 further includes a control unit 11, an angle detection unit 12, an operation detection unit 13, a storage unit 14, and an input / output unit 15. Although not shown, the mobile terminal 10 may have functional units included in various mobile terminals such as a battery, a ROM, a microphone, a speaker, a camera, or a wireless communication unit.

  The control unit 11 is, for example, a CPU that performs overall control of the mobile terminal 10. The angle detection unit 12 is, for example, a rotary encoder that detects an opening / closing angle of the connection unit 40. The motion detection unit 13 is, for example, an acceleration sensor that detects the movement of the first display unit 20 and the second display unit 30, that is, the main body unit (mobile terminal 10). The motion detection unit 13 may be disposed on at least one of the first display unit 20 and the second display unit 30. As will be described later, in the mobile terminal 10, the operation detection unit 13 is a page update instruction detection unit that detects a page update instruction by the user. The storage unit 14 stores application programs, electronic book data, and the like. The input / output unit 15 is an interface for inputting electronic book data or the like to the mobile terminal 10 or transferring the data stored in the storage unit 14 to another terminal.

  The display panel 21 and the display panel 31 are a liquid crystal panel, an organic EL panel, an electrophoretic electronic paper panel, or the like. The first display panel 21 and the second display panel 31 of the mobile terminal 10 preferably have a touch panel input function and are also part of the input / output unit 15.

Next, the operation of the mobile terminal 10 will be described using the flowchart of FIG.
<Step S10> Activation When the portable terminal 10 is activated, it executes an application program such as a document browsing program and waits for various events, for example, a screen showing titles of a plurality of electronic books stored in the storage unit 14. It will be in the state to display.

<Step S <b>11> Initial Display When the user selects a desired electronic book via the touch panel of the first display panel 21, for example, the electronic device selected on the first display panel 21 is controlled by the control unit 11. The first page image of the book is displayed, and the second page image is displayed on the second display panel 31.

  That is, the control unit 11 displays images of continuous pages of the electronic book on the first display unit 20 and the second display unit 30, respectively. Of course, depending on the type of the book, a two-page image of the electronic book is displayed on the first display panel 21, and a one-page image is displayed on the second display panel 31. That is, the order of the page images displayed on the first display unit 20 and the second display unit 30 differs depending on whether the book is so-called right-opening or left-opening.

  When the number of pages (X) that have been read is stored in the storage unit 14 as additional information in the electronic book data selected by the user, it is displayed from the image of the next page (X + 1). The control unit 11 may control.

  Further, the control unit 11 may perform control so that a moving image (animation) for opening a book is displayed when initial display is performed in the same manner as in a page update process described later.

<Step S12> Tilt motion detection? (Page update instruction detected)
The user instructs display page update processing in order to read the next page. That is, the first display panel 21 and the second display panel 31 are instructed to update and display the images of each successive page of the displayed electronic book as an image obtained by adding two pages to the page.
In the mobile terminal 10, when the mobile terminal 10 (main body part) is tilted rightward or leftward, the motion detection unit 13 detects the tilting motion. That is, the operation detection unit 13 is a page update instruction detection unit.

  When the motion detection unit 13 detects a page update instruction, that is, a tilt motion (Yes), the processing from S13 is performed. When the motion detection unit 13 does not detect the tilt motion (No), the mobile terminal 10 waits until the tilt motion is detected (Yes). That is, page update processing is not performed.

<Step S13> Opening / closing angle θ ≧ 180 degrees?
When the motion detection unit 13 detects a tilting motion (S12: Yes), the control unit 11 performs display page update processing. However, if the display page update process is performed based only on the movement of the main body by the motion detection unit 13, the page may change even if the user changes the body orientation during browsing. For this reason, as shown in FIG. 4A, when the opening / closing angle is 180 degrees or more (Yes), even if the motion detection unit 13 detects the tilting motion, the mobile terminal 10 is in the standby state from S12. To maintain. That is, page update processing is not performed.

  On the other hand, as shown in FIG. 4B, when the opening / closing angle θ is less than 180 degrees (No), the page update processing from S14 is performed.

  Note that the opening / closing angle θ that is a criterion for determining whether or not to perform the page update processing is not strictly limited to 180 degrees, and may be approximately 180 degrees, less than 180 degrees, or more than 180 degrees. The person may be able to set it according to his / her preference. Here, substantially 180 degrees is, for example, 180 degrees ± 15 degrees.

<Steps S14 and S15> Leftward tilt? As shown in FIG. 4C, when the direction of the tilt motion detected by the motion detection unit 13 is the left direction (S14: Yes), the control unit 11 displays the display page in S15. The page turning process is performed as an update process. The left-turning process is a process of moving the page displayed on the second display panel 31 on the right side to the left display panel 21 side, and is a process of advancing the displayed page in a left-open book. is there.

  As shown in FIGS. 5A to 5D, during the page turning process, the control unit 11 displays a moving image that turns a book page. FIG. 5A shows an initial display state in which an image of the first page (hereinafter referred to as “one page image”) is displayed on the first display panel 21 and a two page image is displayed on the second display panel 31. Is shown. Note that a page end image 31A indicating that there are a large number of page image data is displayed after the two-page image at the right end of the second display panel 31 in FIG.

  FIG. 5B shows a state in which the second display panel 31 has a two-page image turned and a subsequent four-page image starts to be seen. In FIG. 5C, the 2-page image is further turned, the entire 4-page image is displayed on the second display panel 31, and the 3-page image on the back of the 2-page image is displayed on the first display panel 21. Is displayed and only a part of the one-page image is displayed. FIG. 5D shows a state in which the page left turning process is completed, a 3-page image is displayed on the first display panel 21, and a 4-page image is displayed on the second display panel 31. Yes. That is, the moving image representing page turning is an animation in which two or more still images in the middle of turning pages are sequentially displayed between FIG. 5 (A) and FIG. 5 (D).

  Further, a page end image 21A indicating that there is page image data is displayed at the left end of the first display panel 21 after the third page image.

  As described above, the page turning process is a process of displaying an image with two pages increased on each of the first display panel 21 and the second display panel 31.

  Since the mobile terminal 10 displays a moving image that turns the page during the display page update process, the user can proceed with reading in a manner similar to a paper book.

  Note that the width of the page edge image 21A is smaller than the width of the page edge image 31A, indicating that the page of the first half area of the content of the electronic book is displayed on the display unit. For this reason, the user can proceed with reading while paying attention to the number of remaining pages from the visual information, like a paper book.

<Step S16> Page Right Turning Process As shown in FIG. 4D, when the direction of the tilting motion detected by the motion detection unit 13 is not the left direction (S14: No), that is, the direction of the tilting motion is the right When the direction is the direction, the control unit 11 performs a page turning process as a display page update process in S16. In the page turning process, the first display panel 21 and the second display panel 31 display images obtained by reducing the page by two pages. That is, the page right turning process is a process for returning the displayed page, but is similar to the page left turning process, and thus the description thereof is omitted.

  Of course, in the case of the initial display without the image of the return page, that is, in the case of an electronic book that has been newly read, the control unit 11 does not perform the page return process. Or the control part 11 may perform the moving image display which closes a book, and may perform power supply OFF operation | movement.

<Step S17> End?
The process from S11 is repeatedly performed until the user instructs the end through the touch panel or the like.

  As described above, even when the mobile terminal 10 has an unintended tilting operation during browsing, the first display unit 20 and the second display unit 30 are opened larger than a predetermined opening / closing angle. In the state, display page update processing is not performed. For this reason, the portable terminal 10 has good operability.

  Note that the electronic book is not limited to a simple data file in which a paper book is digitized or imaged, and may be a data file having content to be displayed in page units. That is, an electronic book that is a multimedia platform has various expandability that cannot be realized by a paper book.

  For example, the electronic book may be a music database file in which music data is embedded in lyrics, still images, moving images, or the like displayed on each page. The user can enjoy the music embedded in each page while reading the pages of the music database file composed of a plurality of pages.

  Further, the case where the motion detection unit 13 detects whether the tilting motion is in the right direction or the left direction has been described. However, when the tilting motion speed is detected and the speed is equal to or higher than a predetermined speed, a plurality of pages are separated. You may control so that it may turn. Further, the motion detection unit 13 may detect a tilt in the front-rear direction and perform a predetermined motion according to the detection result.

  Further, the page update instruction is not limited to the tilt movement instruction detected by the movement detection unit 13. For example, when the first display panel 21 or the second display panel 31 is configured by a touch panel, when the user performs an operation of sliding a finger from right to left on the panel, the page is turned left. It may be an instruction or the like.

  Regardless of the page update instruction, the control unit 11 of the mobile terminal 10 does not perform the page turning process when the opening / closing angle θ is within a predetermined angle range. For this reason, since the page turning process not intended by the user is not performed, the mobile terminal 10 has good operability.

  In addition, although embodiment of this invention was described above, this embodiment is shown as an example and is not intending limiting the range of invention. The embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. The embodiments are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
