Description

  The present invention relates to a mobile terminal device including an image display unit and a key operation unit. Specifically, the present invention relates to the structure of the mobile terminal device and the arrangement of the image display unit and the key operation unit.

  In recent years, in mobile terminal devices such as mobile phones, with the advancement of attached functions, not only phone calls and e-mails, but also output of TV images, browsing and searching of Internet sites, use for gaming purposes, etc. Is desired.

  In calls and e-mails, which are the main applications of conventional portable terminal devices, a large-area display is not necessary to display images, and dial keys mainly composed of numeric keys are sufficient for inputting characters. . Therefore, it was possible to arrange a display and a dial key on one surface of the casing of the mobile terminal device.

  However, in order to view TV images comfortably, a display of a larger size has been required. Also, when browsing and searching Internet sites that require complicated operations, conventional dial keys cannot be said to have sufficient operability, and a large area such as keyboard keys and touch panels used for PC operations. There has been a demand for an operation unit that requires the operation.

  One feature of the portable terminal device is that it is small and convenient to carry. Therefore, without increasing the size of the mobile terminal device, there is a demand for increasing the size of the display and installing keyboard keys and touch panels.

  Therefore, in recent years, mobile terminal devices having various structures have been created. Mobile terminal devices that have a display casing having a display and a key casing having an operation unit such as a dial key have appeared. By providing the display and dial keys in different housings, the size of the display is increased.

  Moreover, when carrying a portable terminal device, the compactness of a portable terminal device is maintained by superimposing a display housing and a key housing. As a method of overlapping each case, a method of sliding the case (slide method) and a method of connecting and folding each case with a hinge (folding method) are generally used.

  However, although the size of the display could be increased, keyboard keys have not been provided.

  Therefore, Patent Document 1 discloses a structure in which a display and a keyboard key appear when two housings are opened. FIG. 8A is a perspective view when the portable terminal device disclosed in Patent Document 1 is folded, and FIG. 8B is a perspective view when the portable terminal device is opened. The keyboard key 11 is arranged on a part of the surface formed when the first casing 15 and the second casing 16 are opened (FIG. 8B). A display 5 is provided in a portion of the second casing 16 where the keyboard key 11 is not disposed, and a window 17 is provided in a portion of the first casing 15 where the keyboard key 11 is not disposed. Therefore, when the portable terminal device is folded, the display 5 provided in the second housing 16 can be seen from the window 17 (FIG. 8A). Moreover, since the dial key 8 is provided on the surface opposite to the surface on which the keyboard key 11 is provided of the first casing 15, it can be used as a conventional telephone application when the mobile terminal device is folded. I can do it.

  Furthermore, Patent Document 2 discloses a structure in which a part of a keyboard key that appears when sliding is combined as a dial key by combining a sliding method and a folding method. FIG. 9A is a perspective view when the mobile terminal device disclosed in Patent Document 2 is folded, and FIG. 9B is a perspective view when the mobile terminal device is slid, FIG. 9C is a perspective view when the mobile terminal device is opened. A keyboard key 11 is provided in the key casing 3, and a part of the keyboard key 11 that appears by sliding the display casing 2 is handled as a dial key (FIG. 9B). Moreover, all the keyboard keys 11 appear by opening the display housing 2 (FIG. 9C). Since the display 5 is arranged on the entire surface of the display housing 2 that is in contact with the key housing 3, the display 5 having a large area can be seen when the display housing 2 is opened.

  However, if the window 17 is provided in a part of the first casing 15 as shown in Patent Document 1 shown in FIG. 8, a wide display using the maximum surface of the casing of the mobile terminal device can be arranged. Absent. Although the display 5 can be enlarged instead of the window 17 of the first housing 15, the display 5 cannot be confirmed when the portable terminal device is folded. That is, when the dial key 8 is operated, the display 5 cannot be confirmed, which may impair convenience.

  Convenience is improved by providing a new display on the surface on which the dial key 8 is provided. However, since two displays are provided in one portable terminal device, there is a risk of increasing costs.

  Also in Patent Document 2, a display that can be confirmed with the display housing 2 folded or slid and a display that can be confirmed with the display housing 2 opened are necessary. Since two displays are provided in one portable terminal device, there is a possibility of increasing costs.

  Therefore, the present invention is a portable terminal device in which housings are slidable and foldable, and on a single display, calls and e-mail operations using dial keys, and browsing of Internet sites using keyboard keys It is another object of the present invention to provide a portable terminal device that enables a search operation.
