Description

発明の名称 技術分野 Title of the invention Technical field
本発明は、 文字や画像を表示する液晶表示部を備えた小型携帯電話機に関する ものである。 背景技術  The present invention relates to a small mobile phone provided with a liquid crystal display for displaying characters and images. Background art
近年、 携帯電話機は携帯性の向上のために小型化が進んでいる。 その反面、 電 話機の機能に加えてインターネットゃ各種情報の出力端末としての機能が追加さ れて大容量の情報の表示が可能な液晶表示部が要求されるようになった。 そこで 例えば日本特許公開公報2 0 0 0 - 2 7 8 3 7 3号に示すように、 電話機本体の 前面に設けた第 1液晶表示部の表面に回動パネルを回動自在に設け、 この回動パ ネルの表面並びに裏面に第 2液晶表示部並びに第 3液晶表示部を設けて、 より多 くの表示を行いたい場合は、 回動パネルを開いて第 2液晶表示部並びに第 3液晶 表示部の両者で表示させるようにしたものが提供されている。 2. Description of the Related Art In recent years, miniaturization of mobile phones has been promoted to improve portability. On the other hand, a liquid crystal display unit capable of displaying a large amount of information has been required by adding a function as an output terminal for various kinds of information on the Internet in addition to a function of a telephone. Thus, for example Japanese Patent Publication 2 0 0 0 - 2 7 8 3 7 As shown in No. 3, provided the rotation panel rotatably to the surface of the first liquid crystal display unit provided on a front face of the telephone body, the times To provide more display by providing the second and third liquid crystal display sections on the front and back of the moving panel, open the rotating panel and open the second and third liquid crystal display sections. There is provided one that is displayed on both sides.
しかし、 上記従来タイプでは、 液晶表示部が 3面あるにもかかわらず、 大容量 の情報表示を必要とするときに第 2液晶表示部並びに第 3液晶表示部の 2面しか 活用することが出来ず、 第 1液晶表示部が無駄となってしまう、 といった大きな 欠陥があった。  However, in the above-mentioned conventional type, despite the fact that there are three liquid crystal displays, only two liquid crystal displays, the second and third, can be used when large-capacity information display is required. And the first liquid crystal display was wasted.
そこで本発明は、 通常はコンパク 卜に折り畳まれて普通の携帯電話機と同様に 使用できるものでありながら、 インターネット等の大容量の情報表示を必要とす るときは第 1液晶表示部並びに第 2液晶表示部を第 3液晶表示部と同じ平面上に 展開させることにより全ての液晶画面を利用した無駄のない大領域の表示部を形 成することが出来るようにし、 もって上記従来欠点を解消した携帯電話機を提供 することを主たる目的とするものである。 発明の開示  Therefore, the present invention is intended to be used in the same manner as ordinary mobile phones, usually folded into a compact, but when a large-capacity information display such as the Internet is required, the first liquid crystal display unit and the second liquid crystal display unit are used. By expanding the liquid crystal display unit on the same plane as the third liquid crystal display unit, it is possible to form a large-area display unit using all the liquid crystal screens without waste, thereby eliminating the above-mentioned conventional disadvantages. Its main purpose is to provide mobile phones. Disclosure of the invention
上記目的を達成する為に本発明では次のような技.術的手段を講じた。 即ち、 本 発明にかかる携帯電話機にあっては、 第 1液晶表示部 1、 第 2液晶表示部 2が電 話機本体 5の前面に設けられた第 3液晶表示部 3の前面に展開可能に折り畳まれ ており、 これら液晶表示部 1、 2、 3が同一平面上に展開したときに全ての液晶 表示部 1、 2、 3が前面に向くように形成されており、 更に第 1液晶表示部 1並 びに第 2液晶表示部 2が電話機本体 5に折り畳まれたときに第 1液晶表示部 1が 電話機本体 5の前面に露出し第 3液晶表示部 3が折り畳まれた第 2液晶表示部 2 の背面に隠れるように形成されている構造とした。 これにより通常は電話機本体 5に折り畳まれた第 1液晶表示部 1を使用することによつて普通の携帯電話機と 同様に使用できるものでありながら、 ィンターネット等の大容量の情報表示を必 要とするときは第 1液晶表示部並びに第 2液晶表示部を展開させて第 3液晶表示 部 3と共に大領域の表示部を形成できる。 上記構成に加え、 第 4液晶表示部 4を電話機本体 5の背面に展開可能に折り畳 んでこれを展開したときに電話機本体 5の前面に向くように形成してもよい。 こ れにより更に大領域の表示部を形成することができる。 図面の簡単な説明 In order to achieve the above object, the present invention takes the following technical means. That is, the book In the mobile phone according to the invention, the first liquid crystal display unit 1 and the second liquid crystal display unit 2 are foldably expandable on the front surface of the third liquid crystal display unit 3 provided on the front surface of the phone body 5. The liquid crystal display units 1, 2 , and 3 are formed so that all of the liquid crystal display units 1, 2, and 3 face the front when the liquid crystal display units 1, 2, and 3 are developed on the same plane. (2) When the liquid crystal display section (2) is folded on the phone body (5), the first liquid crystal display section (1) is exposed on the front face of the phone body (5) and the third liquid crystal display section (3) is hidden behind the folded second liquid crystal display section (2) The structure was formed as follows. As a result, although the first liquid crystal display unit 1 folded on the telephone body 5 can be used in the same manner as an ordinary mobile phone, it is necessary to display a large amount of information such as the Internet. When necessary, the first liquid crystal display section and the second liquid crystal display section can be expanded to form a large area display section together with the third liquid crystal display section 3. In addition to the above configuration, the fourth liquid crystal display unit 4 may be formed so as to be expandable on the rear surface of the telephone body 5 so as to face the front surface of the telephone body 5 when expanded. As a result, a display portion of a larger area can be formed. BRIEF DESCRIPTION OF THE FIGURES
