Abstract

<P>PROBLEM TO BE SOLVED: To obtain a mobile communication terminal capable of controlling display contents of a display portion without adding any special key. <P>SOLUTION: The mobile communication terminal including a 1st case having a display portion 3, a 2nd case 2 having a key operation portion, and a two-axial hinge portion 5 bearing those 1st and 2nd cases 1 and 2 pivotally on mutually orthogonal axes uses the rotational state of the two-axial hinge portion 5 as a substitute for key operation. Namely, when the hinge portion 5 is rotated as shown by an arrow A, the display screen of the display portion 3 is brought under corresponding scroll control to the left in Fig. and when the hinge portion 5 is reversed, the display screen is brought under scroll control to the right. Consequently, the display screen can be controlled even when the key operation portion is hidden, so the need for a special key is eliminated. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は携帯通信端末に関し、特に表示部を有する第一筐体と操作部を有する第二筐体とが、二軸ヒンジ部によつて互いに直交する軸を中心に回動自在に軸支された構造の携帯通信端末に関するものである。   The present invention relates to a mobile communication terminal, and in particular, a first casing having a display unit and a second casing having an operation unit are pivotally supported by a biaxial hinge unit so as to be rotatable around axes orthogonal to each other. The present invention relates to a portable communication terminal having a different structure.

図５はこの種の携帯通信端末を説明するための外観図であり、（ａ）に示すように、基本的に、この種の携帯通信端末は、ＬＣＤ表示部３を有する第一筐体１と、キー操作部４を有する第二筐体２と、これら第一及び第二筐体を互いに回動自在に軸支する二軸ヒンジ部５とからなる。この種の二軸ヒンジ機構を有する携帯通信端末については、特許文献１，２，３などに開示されており、周知である。なお、６は第二筐体２の側面に設けられた側面操作キーを示しており、その用途は後述する。   FIG. 5 is an external view for explaining this type of mobile communication terminal. As shown in FIG. 5A, this type of mobile communication terminal basically includes a first casing 1 having an LCD display unit 3. And a second housing 2 having a key operation portion 4 and a biaxial hinge portion 5 that pivotally supports the first and second housings in a mutually rotatable manner. A portable communication terminal having this type of biaxial hinge mechanism is disclosed in Patent Documents 1, 2, 3 and the like and is well known. Reference numeral 6 denotes a side operation key provided on the side surface of the second housing 2, and its use will be described later.

二軸ヒンジ部５は、図示せぬ互いに直交する二つの回動軸を有しており、一つの回動軸を中心に、第一筐体１が第二筐体２に対して開閉自在となる。この場合の開状態の平面図を（ａ）に示している。この状態において、表示部３を有する第一筐体１を図面の平面内で回動させることができ、その様子を（ｂ），（ｃ）に示す。更に、第一筐体１を回動させると、（ｄ）のように、第一及び第二筐体同士が重なり合って、表示部３のみがユーザと対向するようになる。   The biaxial hinge part 5 has two rotation shafts (not shown) orthogonal to each other, and the first housing 1 can be opened and closed with respect to the second housing 2 around one rotation shaft. Become. A plan view of the open state in this case is shown in FIG. In this state, the 1st housing | casing 1 which has the display part 3 can be rotated within the plane of drawing, and the mode is shown to (b), (c). Further, when the first housing 1 is rotated, the first and second housings overlap each other as shown in (d), and only the display unit 3 faces the user.

この（ｄ）の状態で、ユーザは表示部３の表示内容を見ることができるが、その表示内容をスクロールする必要がある場合に、ユーザは側面操作キー６を使用することになる。   In this state (d), the user can see the display content of the display unit 3, but when the display content needs to be scrolled, the user uses the side operation key 6.

特開平１１−２１５２１８号公報Japanese Patent Laid-Open No. 11-215218 特開２００４−１２８８５０号公報JP 2004-128850 A 特開２００２−１３５３８０号公報JP 2002-135380 A

このように、第一及び第二筐体同士が重なり合って、表示部３のみがユーザと対向するような場合に、表示内容をスクロールするためのキーを、筐体側面などに設けることが必要となり、よって筐体サイズへの影響や、筐体デザインの自由度が低下してしまうという問題点がある。   As described above, when the first and second casings overlap each other and only the display unit 3 faces the user, it is necessary to provide a key for scrolling display contents on the side of the casing. Therefore, there is a problem that the influence on the case size and the degree of freedom in case design are reduced.

本発明の目的は、特別のキーを付加することなく表示部における表示内容の制御を行うことが可能な携帯通信端末を提供することである。   An object of the present invention is to provide a portable communication terminal capable of controlling display contents on a display unit without adding a special key.

本発明による携帯通信端末は、表示部を有する第一筐体と、操作部を有する第二筐体と、前記第一及び第二筐体を互いに回動自在に軸支するヒンジ部とを含む携帯通信端末であって、前記ヒンジ部の回転状態をキー操作の代替としてなることを特徴とする。   A mobile communication terminal according to the present invention includes a first housing having a display unit, a second housing having an operation unit, and a hinge unit that pivotally supports the first and second housings with respect to each other. The portable communication terminal is characterized in that the rotation state of the hinge portion is used as an alternative to a key operation.

そして、前記ヒンジ部は、前記第一及び第二筐体を互いに直交する軸を中心に回動自在軸支する二軸ヒンジ部であり、前記第一及び第二筐体が重ね合わされた状態でかつ前記表示部がユーザと対向する位置にある場合に、前記ヒンジ部の回転状態に応じて前記表示部の制御をなす制御手段を含むことを特徴とする。   The hinge portion is a biaxial hinge portion that pivotally supports the first and second housings about axes orthogonal to each other, and the first and second housings are overlapped with each other. And when the said display part exists in the position which opposes a user, the control means which controls the said display part according to the rotation state of the said hinge part is included, It is characterized by the above-mentioned.

そして、前記制御手段は、前記ヒンジ部の回転方向に応じて前記表示部のスクロール制御をなすことを特徴とし、また、前記制御手段は、前記ヒンジ部の回転角に応じて前記表示部のスクロール制御をなすことを特徴とし、更に、前記制御手段は、前記ヒンジ部の回転速度に応じて前記表示部のスクロール制御をなすことを特徴とする。   The control means performs scroll control of the display unit according to a rotation direction of the hinge part, and the control means scrolls the display part according to a rotation angle of the hinge part. Further, the control unit is characterized in that the control unit performs scroll control of the display unit in accordance with a rotation speed of the hinge unit.

本発明によれば、二軸ヒンジ機構を採用した携帯通信端末において、このヒンジ機構の回転状態を操作キーの代替として使用するようにしたので、筐体同士が重なった場合にも、このヒンジ機構の回転状態により表示部の表示制御が可能となり、よって筐体に操作キーを設ける必要がなくなり、筐体の小形化、筐体の設計の自由度の向上及びユーザの操作性の向上が図れ、またコスト的にも削減が可能となるという効果がある。   According to the present invention, in the portable communication terminal adopting the biaxial hinge mechanism, the rotation state of the hinge mechanism is used as an alternative to the operation key. Therefore, even when the casings overlap each other, the hinge mechanism The display state of the display unit can be controlled according to the rotation state of the display unit.Therefore, there is no need to provide an operation key on the housing, and the housing can be downsized, the design flexibility of the housing can be improved, and the user operability can be improved In addition, there is an effect that the cost can be reduced.

以下に、本発明の実施の形態について図面を参照しつつ説明する。図１は本発明の実施の形態を示す外観図であり、図５と同等部分は同一符号にて示している。本実施の形態における携帯通信端末の構造は、図５の側面操作キー６がないこと以外は図５と同等であり、第一及び第二の筐体１，２及び二軸ヒンジ部５との関係は図５の例と同じである。図１においては、図５（ｄ）と同様に、第一筐体１同士が重なり合って、表示部３のみがユーザと対向している状態を示している。   Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external view showing an embodiment of the present invention, and parts equivalent to those in FIG. The structure of the mobile communication terminal according to the present embodiment is the same as that of FIG. 5 except that the side operation key 6 of FIG. 5 is not provided. The relationship is the same as in the example of FIG. In FIG. 1, as in FIG. 5D, the first housings 1 overlap with each other, and only the display unit 3 faces the user.

この状態において、図２に示すように、ユーザによって、第一筐体１が第二筐体２に対して、矢印Ａに示す方向に、微量に回転されたとき、二軸ヒンジ部５の回転方向を検出して、表示部３に表示されている内容を、当該方向、すなわち図の左方向にスクロールさせるよう制御する。   In this state, as shown in FIG. 2, when the user rotates the first casing 1 with respect to the second casing 2 in a small amount in the direction indicated by the arrow A, the biaxial hinge 5 rotates. The direction is detected, and the content displayed on the display unit 3 is controlled to scroll in the direction, that is, the left direction in the figure.

また、図３に示すように、ユーザによって、第一筐体１が第二筐体２に対して、矢印Ｂに示す方向に、微量に回転されたとき、この回転方向を検出して、表示部３に表示されている内容を、当該方向、すなわち図の右方向にスクロールさせるよう制御する。   Also, as shown in FIG. 3, when the user rotates the first housing 1 with respect to the second housing 2 in a small amount in the direction indicated by the arrow B, this rotational direction is detected and displayed. Control is performed so that the content displayed in the section 3 is scrolled in the direction, that is, in the right direction in the figure.

こうすることにより、本来のキー操作部などからのキー操作なしに、表示部３の表示内容の制御が可能となって表示情報の閲覧が自在となる。従って、図５に示したように、筐体側面などに特別の操作キー６を設ける必要が全くなくなるのである。   By doing so, the display contents of the display unit 3 can be controlled and the display information can be browsed without any key operation from the original key operation unit or the like. Therefore, as shown in FIG. 5, it is not necessary to provide special operation keys 6 on the side of the casing.

また、他の例として、ヒンジ部５における回動角に応じて、表示画面のスクロール速度の制御を行うようにすることも考えられる。すなわち、回動角が大なる場合には、スクロール速度を早くし、回動角が小なる場合には、スクロール速度を遅くするのである。また、ヒンジ部５の回転速度の大小によってスクロール速度を制御することも考えられる。   As another example, it is conceivable to control the scroll speed of the display screen according to the rotation angle of the hinge unit 5. That is, when the rotation angle is large, the scroll speed is increased, and when the rotation angle is small, the scroll speed is decreased. It is also conceivable to control the scrolling speed according to the rotational speed of the hinge part 5.
