Abstract

A conventional electronic device with a stereo viewer takes a lot of trouble with switching between a 2D display (normal display) and a 3D display (three-dimensional display) and has poor portability due to its difficulty in reduction in thickness. A casing of a display element and a cover of the casing on the back surface are connected to each other with a first rotary shaft, the cover and a binocular lens are connected to each other with a second rotary shaft, and the cover and the binocular lens are rotated by approximately 270 degrees, respectively, thereby performing the 3D display, in which the binocular lens is disposed in parallel to the display element, and the 2D display, in which the binocular lens is contained in the casing, at the same time, with the result that the thin and highly portable electronic device with the 3D display function is capable of being achieved.

Description

電子機器、携帯端末装置及び立体画像表示用双眼レンズアダプタElectronic device, portable terminal device and binocular lens adapter for stereoscopic image display
　本発明は、薄型の携帯電話や携帯端末や電子機器に用いられる表示装置に関するものである。 The present invention relates to a display device used for a thin mobile phone, a mobile terminal, and an electronic device.
　携帯電話などの携帯端末装置の表示素子は携帯性を考慮し、薄型で３～４インチの小型なものが用いられている。 In view of portability, a thin display of 3 to 4 inches is used as a display element of a mobile terminal device such as a mobile phone.
　また、表示素子は高精細化が進み、多量の情報を表示することが可能になったが、携帯端末の表示素子で表示した文字や画像は、細かすぎて見にくくなるという課題がある。 Further, with the progress of high definition in display elements, it has become possible to display a large amount of information, but there is a problem that characters and images displayed by the display element of the portable terminal become too fine to be seen.
　メガネを使わずに表示素子で立体画像（３Ｄ画像）を再生するには、例えば視差バリア方式による３Ｄ表示方法がある（例えば特許文献１参照）。しかし、携帯端末などの小型の表示素子では画面が小さいために、立体画像の臨場感が失われる。 In order to reproduce a stereoscopic image (3D image) with a display element without using glasses, for example, there is a 3D display method using a parallax barrier method (see, for example, Patent Document 1). However, in a small display element such as a portable terminal, since the screen is small, the sense of reality of the stereoscopic image is lost.
　左目視線の左画像と右目視線の右画像を横に並べたサイドバイサイドのステレオ画像を、それぞれ左右の目で見ることにより、３Ｄ画像を表示するステレオビューアを用いた方式が知られている。 There is known a method using a stereo viewer that displays a 3D image by viewing the side-by-side stereo image in which the left image of the left visual line and the right image of the right visual line are arranged side by side.
　本方式は小型表示素子でも臨場感のある３Ｄ画像を表示することができる（例えば特許文献２参照や特許文献３参照）。図１６は従来のステレオビューアによる立体（３Ｄ）写真再生装置である。 According to this method, even a small display element can display a realistic 3D image (see, for example, Patent Document 2 and Patent Document 3). FIG. 16 shows a conventional stereo viewer-based three-dimensional (3D) photo reproduction apparatus.
　写真枠３８に合わせてステレオ写真３７を配置し、写真位置から距離をおいて配置した２つの凸レンズ７からなる双眼レンズ６を通して左右の画像をそれぞれ左右の目で見ることにより立体表示が可能になる。 Stereoscopic display 37 is possible by arranging a stereophotograph 37 according to the photographic frame 38 and viewing the left and right images with the left and right eyes through the binocular lens 6 consisting of two convex lenses 7 arranged at a distance from the photograph position .
　写真枠３８とアーム３６と双眼レンズ６は、図１６（２）に示すように、２つの回動軸３９により折畳み可能な構造を有している。 The photographic frame 38, the arm 36, and the binocular lens 6 have a structure that can be folded by two pivot shafts 39, as shown in FIG.
　また、電子機器の表示素子（ディスプレイ）の側面に双眼レンズ付きアーム部品を固定することで、表示素子に表示したステレオ画像を立体画像として再生する方法が提案されている（例えば特許文献４参照）。 There is also proposed a method of reproducing a stereo image displayed on a display element as a stereoscopic image by fixing an arm component with a binocular lens to the side surface of a display element (display) of an electronic device (see, for example, Patent Document 4) .

　従来の特許文献３に記載された、立体（３Ｄ）画像の表示素子を有する電子機器は、アームを表示素子の周囲の筐体枠に固定する構造を有しているため、携帯性が悪かった。　　　　 The electronic device having a display element of a three-dimensional (3D) image described in the conventional patent document 3 has a structure in which an arm is fixed to a casing frame around the display element, so the portability is bad. .
　電子機器を携帯しやすくするためにアームを電子機器から取り外すことは可能であるが、電子機器本体と双眼レンズを含むアームを別々に携帯する必要があり、持ち運びには適さなかった。 Although it is possible to remove the arm from the electronic device in order to make the electronic device easy to carry, it is necessary to separately carry the electronic device body and the arm including the binocular lens, which is not suitable for carrying.
　また、携帯電話や携帯端末のような電子機器では通話、メール、テレビ、カメラなど多くの機能を有し、立体画像表示（３Ｄ表示）でなくても使用できる機能がむしろ多い。立体画像ではない従来の表示画面（２Ｄ表示）で操作を行うときには、アームが邪魔になってしまう。または、アームを取り外す手間がかかってしまう。 In addition, electronic devices such as mobile phones and mobile terminals have many functions such as telephone calls, e-mails, televisions, cameras, etc., and many functions can be used even without stereoscopic image display (3D display). When performing an operation on a conventional display screen (2D display) that is not a stereoscopic image, the arm is in the way. Or, it takes time to remove the arm.
　例えば、特許文献１や特許文献２に記載された折畳み機能を有するステレオビューアを電子機器の表示素子上に取り付ければ、持ち運びがしやすくなる。 For example, if a stereo viewer having a folding function described in Patent Document 1 or Patent Document 2 is mounted on a display element of an electronic device, it can be easily carried.
　しかし、特許文献１や特許文献２に記載されたステレオビューアは双眼レンズがステレオ画像上に収納される構造を有しているため、従来の表示画面による操作を行うことができない。すなわちメールなどの従来機能の操作性が非常に悪くなってしまう。 However, the stereo viewers described in Patent Document 1 and Patent Document 2 have a structure in which a binocular lens is accommodated on a stereo image, and therefore, it is impossible to perform an operation using a conventional display screen. That is, the operability of the conventional functions such as e-mail becomes very bad.

（実施の形態１）
　図１は、本実施の形態の携帯端末装置の概略斜視構造図である。図１（１）は、上筺体１を回転した状態を示す概略構造図である。同図（２）は、更にカバー５を回転した状態を示す概略構造図である。同図（３）は、更に双眼レンズ６を回転した状態を示す概略構成図である。同図（４）は、後述する第一形態を示す概略構造図である。同図（５）は、後述する第二形態を示す概略構造図である。 Embodiment 1
FIG. 1 is a schematic perspective view of the portable terminal device of the present embodiment. FIG. 1 (1) is a schematic structural view showing a state in which the upper housing 1 is rotated. The same figure (2) is a schematic structural drawing which shows the state which rotated the cover 5 further. The same figure (3) is a schematic block diagram which shows the state which rotated the binocular lens 6 further. The same figure (4) is a schematic structure figure which shows the 1st form mentioned later. The figure (5) is a schematic structure figure which shows the 2nd form mentioned later.
　以下、本実施の形態１では折畳み型の携帯端末装置に適用した場合を例に説明するが、その他、ポータブルなカーナビゲーションやテレビなど、表示素子を有する薄型電子機器に適用した場合も同様である。 Hereinafter, although the case where it applies to a folding-type portable terminal device is explained to an example in this Embodiment 1, it is the same also when applying to thin electronic equipment which has a display element, such as portable car navigation and television, etc. .
　本実施の形態の携帯端末装置は、図１（１）に示すように、上筐体１と下筐体３からなる折畳み型携帯端末装置であり、上筐体１には第一表示素子２（メインディスプレイ）、カバー５、双眼レンズ６などが設けられている。下筐体３には操作キー１２が設けられている。 The portable terminal device of the present embodiment is, as shown in FIG. 1 (1), a foldable portable terminal device comprising an upper case 1 and a lower case 3, and the upper case 1 has a first display element 2. A (main display), a cover 5, a binocular lens 6, etc. are provided. The lower housing 3 is provided with an operation key 12.
　第一表示素子２は長方形状を有していて、図１（５）に示すように、上筐体を長辺に平行なヒンジ４を回転すると、第一表示素子２の長辺が水平となり、その下部には操作キーが配置される。これは、従来の携帯端末装置の使用形態の一例であり、ここでは第一形態と呼ぶことにする。 The first display element 2 has a rectangular shape, and as shown in FIG. 1 (5), when the hinge 4 parallel to the long side rotates the upper housing, the long side of the first display element 2 becomes horizontal. The operation key is arranged at the lower part thereof. This is an example of the usage form of the conventional portable terminal device, and will be referred to as a first form here.
　なお、第一表示素子２の長辺が垂直である状態で表示した使用形態も可能でありこれも第一形態に含まれる。 In addition, the use form displayed in the state which the long side of the 1st display element 2 is perpendicular | vertical is also possible, and this is also contained in a 1st form.
　第一形態においては、第一表示素子は従来のように、縦向きまたは横向きの画面を用いて情報を表示する。これを第一表示モードまたは、通常表示（２Ｄ表示）と呼ぶことにする。 In the first embodiment, the first display element displays information using a screen in portrait or landscape orientation, as is conventional. This is called a first display mode or a normal display (2D display).
　図１（２）から（４）に示すように、上筐体１の第一表示素子２と反対面にあるカバー５を第一回動軸８の回りに回転し、さらに第二回動軸９を中心に双眼レンズ６を回転することで、図１（４）に示すように、双眼レンズ６と第一表示素子２とが所定距離だけ離れた場所に平行に配置することができ、立体画像を表示するためのステレオビューア構造が実現できる。これを第二形態と呼ぶことにする。 As shown in FIGS. 1 (2) to 1 (4), the cover 5 on the surface opposite to the first display element 2 of the upper housing 1 is rotated about the first rotation shaft 8, and the second rotation shaft By rotating the binocular lens 6 centering on 9, as shown in FIG. 1 (4), the binocular lens 6 and the first display element 2 can be arranged in parallel in a place separated by a predetermined distance. A stereo viewer structure for displaying an image can be realized. This will be called the second form.
　第二形態では、図１（４）に示すように、第一表示素子２を左画面１１と右画面１０の２画面に分割して左右それぞれ、左目用画像と右目用画像を表示する。これを第二表示モードまたは、立体表示（３Ｄ表示）と呼ぶ。双眼レンズ６は２つの凸レンズからなり、ユーザが上記の左画面と右画面をそれぞれ左右の目で見ることにより、立体画像（３Ｄ画像）を再現することができる。 In the second embodiment, as shown in FIG. 1 (4), the first display element 2 is divided into two screens, the left screen 11 and the right screen 10, and the left eye image and the right eye image are displayed respectively on the left and right. This is called a second display mode or stereoscopic display (3D display). The binocular lens 6 is composed of two convex lenses, and the user can reproduce a stereoscopic image (3D image) by looking at the left screen and the right screen respectively with the left and right eyes.
　図２には本実施の形態の携帯端末装置の概略断面構造図を示す。図２（１）は２Ｄ表示を行う第一形態を示す概略構造断面図である。同図（２）は、カバー５を回転した状態を示す概略構造断面図である。同図（３）は、双眼レンズ６を回転した状態を示す概略構造断面図である。同図（４）は、立体表示を行う第二形態を示す概略構造断面図である。 FIG. 2 shows a schematic cross-sectional structure view of the portable terminal device of the present embodiment. FIG. 2A is a schematic structural cross-sectional view showing a first mode for performing 2D display. The figure (2) is a schematic structure sectional view which shows the state which rotated the cover 5. The same figure (3) is a schematic structural sectional view showing a state in which the binocular lens 6 is rotated. The same figure (4) is schematic structure sectional drawing which shows the 2nd form which performs three-dimensional display.
　第一形態から第二形態に変化させるには、第一回動軸８を中心にカバー５を上筐体１に対する右回りの回転角θ１が約２７０度になるまで回転したのち、第二回動軸９を中心に双眼レンズ６をカバー５に対する右回りの回転角θ２が約２７０度になるまで回転する。 In order to change from the first form to the second form, the cover 5 is rotated about the first rotation axis 8 until the clockwise rotation angle θ1 with respect to the upper housing 1 becomes about 270 degrees, and then the second The binocular lens 6 is rotated about the motion axis 9 until the clockwise rotation angle θ2 with respect to the cover 5 is about 270 degrees.
　なお、第一表示素子と双眼レンズがほぼ平行になれば、θ１とθ２はともに２７０度でなくとも構わない。例えばθ１とθ２の和が約５４０度であれば、第一表示素子と双眼レンズがほぼ平行になる。 If the first display element and the binocular lens are almost parallel, both θ1 and θ2 do not have to be 270 degrees. For example, if the sum of θ1 and θ2 is about 540 degrees, the first display element and the binocular lens become almost parallel.
　図３は、本発明の実施の形態１の携帯端末装置のカバー５と上筐体１の接続部の構造図とカバー５の断面図を示す。図３（１）は、本実施の形態の携帯端末装置のカバー５と上筐体１の接続部の構造図を示す。同図（２）は、カバー５のＡ－Ａ’線に沿った第一形態の断面図を示す。 FIG. 3 shows a structural view of a connection portion between the cover 5 and the upper housing 1 of the mobile terminal device according to the first embodiment of the present invention and a cross-sectional view of the cover 5. FIG. 3 (1) shows a structural view of a connection portion between the cover 5 and the upper case 1 of the portable terminal device of the present embodiment. The same figure (2) shows a cross-sectional view of the first embodiment along the line A-A 'of the cover 5.
　図３（１）のように、カバー５の長辺部分にはカバー側軸受け１５、上筐体１側には軸受け１３を有し、軸１４によりカバー５と上筐体１を結合し、第一ヒンジ１６が完成する。軸受け１３と上筐体１が固定されている面を結合面といい、上筐体１の結合面を第一結合面２２（図６参照）、軸受け側の結合面を第二結合面２３と呼ぶ（図６参照）。 As shown in FIG. 3 (1), the cover 5 has a cover-side bearing 15 at the long side of the cover 5 and the bearing 13 at the upper housing 1 side, and the shaft 5 couples the cover 5 and the upper housing 1 One hinge 16 is completed. The surface on which the bearing 13 and the upper housing 1 are fixed is referred to as a coupling surface, the coupling surface of the upper housing 1 is referred to as a first coupling surface 22 (see FIG. 6), and the coupling surface on the bearing side is referred to as a second coupling surface 23 Call (see Figure 6).
　図３（１）に記載されているカバー５のＡ－Ａ’線に沿った第一形態の断面図を図３（２）に示す。カバー５の短辺の上筐体１側に枠１７があり、それと対抗する上筐体１側には溝１８がある。この枠１７は第二形態においてカバー５がしなって曲がりやすくなることを防止する効果を有している。第一形態においては溝１８と枠１７が重なることにより枠１７の突起が邪魔になることなく、カバー５及び双眼レンズ６を薄型形状のままに収容できる。 A cross-sectional view of a first embodiment of the cover 5 taken along the line A-A 'shown in FIG. 3 (1) is shown in FIG. 3 (2). A frame 17 is provided on the upper case 1 side of the short side of the cover 5 and a groove 18 is provided on the opposite side of the upper case 1. The frame 17 has an effect of preventing the cover 5 from being easily bent in the second embodiment. In the first embodiment, as the groove 18 and the frame 17 overlap, the cover 5 and the binocular lens 6 can be accommodated in the thin shape without the projection of the frame 17 becoming an obstacle.
　図４は第二形態におけるカバー５及び双眼レンズ６の構造図を示す。 FIG. 4 shows a structural view of the cover 5 and the binocular lens 6 in the second embodiment.
　第一形態から、上筐体１に対して第一ヒンジ１６を２７０度回転したのち、第二ヒンジ１９を２７０度回転することで、図４の第二形態を得る。枠１７は双眼レンズ６などの重さでカバーがしなることを防止する効果を有している。 From the first embodiment, after the first hinge 16 is rotated 270 degrees with respect to the upper housing 1, the second hinge 19 is rotated 270 degrees to obtain the second embodiment of FIG. The frame 17 has an effect of preventing covering by the weight of the binocular lens 6 or the like.
　カバーは例えば樹脂材料からなり、できる限り非透明にすることで、表示素子面に外部光が差し込むことが少なくなり、表示画面が見やすくなる。 The cover is made of, for example, a resin material, and by making it as non-transparent as possible, external light is less likely to be inserted into the display element surface, and the display screen can be easily viewed.
　双眼レンズ６は２つの凸レンズ７からなり、以下の３つの機能をもつ。
（１）第一表示素子２に表示された左右画面を分離して見えるようにする。
（２）画面表示を拡大する。
（３）ユーザと左右画面の距離が近距離でも焦点を結ぶことができる。従って、ユーザの視野に対して画面の占める割合（視野角）を大きくすることができる。 The binocular lens 6 comprises two convex lenses 7 and has the following three functions.
(1) The left and right screens displayed on the first display element 2 are separated and viewed.
(2) Enlarge the screen display.
(3) Even when the distance between the user and the left and right screens is close, focusing can be achieved. Therefore, the ratio (viewing angle) of the screen to the field of view of the user can be increased.
　従来の３インチ程度の表示画面をもつ携帯端末装置の第一形態での表示では、図２（１）に示すように、ユーザの目と画面の距離が約２０ｃｍ程度離れた状態で使用することが多い。このときは視野角が約２０度程度となる。 As shown in FIG. 2 (1), the conventional display of the portable terminal having a display screen of about 3 inches is used with the distance between the user's eyes and the screen about 20 cm apart There are many. At this time, the viewing angle is about 20 degrees.
　一方、第二形態の３Ｄ表示モードでは、図２（４）に示すように双眼レンズ６に凸レンズを用いることにより近距離で焦点を結ぶことが可能になるため、ユーザの目と画面間距離が１０ｃｍ程度に小さくすることができる。これにより視野角が４０度以上となり臨場感のある３Ｄ画像（映像）を得ることができる。 On the other hand, in the 3D display mode of the second embodiment, as shown in FIG. 2 (4), it is possible to focus at a short distance by using a convex lens for the binocular lens 6, so the distance between the user's eye and the screen It can be as small as 10 cm. As a result, the viewing angle becomes 40 degrees or more, and a realistic 3D image (video) can be obtained.
　なお、凸レンズの倍率はルーペ等で利用される数倍の倍率、すなわち焦点距離が５ｃｍ～１５ｃｍ程度の低倍率のものが適している。倍率を大きくしすぎると左右画面が視野全体に収まらず、一部しか見えなくなるとともに、画素の粗さが目立ってくる。逆に倍率を小さくしすぎるとユーザと画面の距離を長くしないと焦点を結ぶことが困難となり、視野角が小さくなる。 The magnification of the convex lens is preferably several times the magnification used in a loupe or the like, that is, a low magnification having a focal length of about 5 cm to 15 cm. If the magnification is too large, the left and right screens do not fit in the entire field of view, and only a part of them can be seen, and the roughness of the pixels becomes noticeable. Conversely, if the magnification is too small, it will be difficult to focus if the distance between the user and the screen is not long, and the viewing angle will be small.
　なお、凸レンズは通常のガラスまたは透明樹脂製の凸レンズで構わないが、フレネルレンズを用いることによってより薄型化が可能となる。 In addition, although a convex lens may be a convex lens made of normal glass or transparent resin, thickness reduction becomes possible by using a Fresnel lens.
　図５は第一回動軸８の詳細断面構造図を示す。同図（１）は、カバー５を回転した状態を示す詳細断面構造図である。同図（２）は、カバー５を第一回動軸８の回りに２７０度回転させた状態を示す詳細断面構造図である。即ち、カバー５を第一回動軸８の回りに２７０度回転させた構造を図５（２）に示す。第一回動軸８が上筐体１の表示素子２とは反対側の面に近いほうに配置されていることにより、カバー５が２７０度回転したときに上筐体１の外側の側面と接して、その位置で保持することができるようになる。 FIG. 5 shows a detailed cross-sectional structural view of the first rotation shaft 8. The figure (1) is a detailed cross-section figure which shows the state which rotated the cover 5. FIG. FIG. 2B is a detailed cross-sectional structural view showing a state in which the cover 5 is rotated 270 degrees around the first rotation shaft 8. That is, a structure in which the cover 5 is rotated 270 degrees around the first rotation shaft 8 is shown in FIG. Since the first pivot shaft 8 is disposed closer to the surface of the upper housing 1 opposite to the display element 2, when the cover 5 is rotated 270 degrees, the outer side surface of the upper housing 1 and It comes to be able to hold in that position.
　従って、新たにストッパ部品などを追加して２７０度以上回転しないようにすることが不要となる。 Therefore, it is not necessary to add a stopper part or the like to prevent rotation by 270 degrees or more.
　図６は第一ヒンジ１６の軸受け１３と上筐体１に応力が加わった場合に、分離する機能の一例を示す。同図（１）は、外部応力２４が加わる前の第一回動軸８と軸受け１３の詳細構造図である。同図（２）は、外部応力２４が加わったときの第一回動軸８と軸受け１３の詳細構造図である。同図（３）は、第一のガイド２０から軸受け１３がはずれたときの第一回動軸８と軸受け１３の詳細構造図である。同図（４）は、軸受け１３の機能を説明する説明図である。 FIG. 6 shows an example of the separation function when the bearing 13 of the first hinge 16 and the upper housing 1 are stressed. FIG. 1A is a detailed structural view of the first rotating shaft 8 and the bearing 13 before the external stress 24 is applied. The figure (2) is a detailed structure figure of the 1st rotational axis 8 and bearing 13 when external stress 24 is added. FIG. 3C is a detailed structural view of the first pivot shaft 8 and the bearing 13 when the bearing 13 is detached from the first guide 20. The figure (4) is explanatory drawing explaining the function of the bearing 13. As shown in FIG.
　第二形態において、例えば落下などにより、図６に示す矢印の方向に外部応力２４が必要以上に加わると、第一ヒンジ１６に応力が集中し部品が破壊されるおそれがある。そこで、外部応力２４が加わったときには、部品を破壊させることなく軸受け１３がはずれる機能が有効である。 In the second embodiment, if the external stress 24 is applied more than necessary in the direction of the arrow shown in FIG. 6 due to, for example, dropping, the stress may concentrate on the first hinge 16 and the part may be broken. Therefore, when the external stress 24 is applied, the function of disengaging the bearing 13 without damaging the parts is effective.
　軸受け１３は図６（４）に示すように、第一のガイド２０により一定方向にスライドする機能を有する。また、軸受け１３と上筐体１は、図６（１）に示すように磁石２１により固定されていて、応力が加わっていないときは、軸受け１３が所定の位置に保持されている。 The bearing 13 has a function of sliding in a fixed direction by the first guide 20, as shown in FIG. 6 (4). Further, the bearing 13 and the upper housing 1 are fixed by the magnet 21 as shown in FIG. 6 (1), and when no stress is applied, the bearing 13 is held at a predetermined position.
　以上の構成により、図６（２）のように外部応力２４が加わったとき、軸受け１３は図６（２）の上方へスライドして、最終的に図６（３）のように第一のガイド２０からはずれることが可能となる。 With the above configuration, when external stress 24 is applied as shown in FIG. 6 (2), the bearing 13 slides upward in FIG. 6 (2), and finally the first as shown in FIG. 6 (3). It is possible to move off the guide 20.
　図７は、バネ２５を用いて軸受け１３と上筐体が完全に分離しないようにしたものである。同図（１）は、軸受け１３の側面図である。同図（２）は、軸受け１３の構造斜視図である。これにより、カバー５が上筐体１からはずれてもカバー５が紛失することがない。なお、バネの代わりに伸縮性を有するゴムなどの材料を用いても構わない。 FIG. 7 shows that the bearing 13 and the upper housing are not completely separated by using a spring 25. The figure (1) is a side view of the bearing 13. FIG. 2B is a structural perspective view of the bearing 13. Thereby, even if the cover 5 is removed from the upper housing 1, the cover 5 is not lost. In addition, you may use materials, such as rubber | gum which has elasticity, instead of a spring.
　なお、図６の磁石と図７のバネを組み合わせても構わない。 The magnet of FIG. 6 and the spring of FIG. 7 may be combined.
　図８は、第二ヒンジ１９によりカバー５と双眼レンズ６が回転する断面構造図である。 FIG. 8 is a sectional structural view in which the cover 5 and the binocular lens 6 are rotated by the second hinge 19.
　外部応力２４が加わると第二ヒンジ１９に応力が集中する。 When the external stress 24 is applied, the stress is concentrated on the second hinge 19.
　双眼レンズ６は樹脂材料のフレネルレンズを用いれば、外部応力２４により湾曲することで第二ヒンジ１９の応力集中を低減できる。また、外部応力２４により第一ヒンジ１６の軸受け１３が先にはずれることにより、第二ヒンジ１９への応力集中は低減できる。 By using a Fresnel lens made of a resin material, the binocular lens 6 can be curved by the external stress 24 to reduce the stress concentration of the second hinge 19. In addition, the stress concentration on the second hinge 19 can be reduced by shifting the bearing 13 of the first hinge 16 first due to the external stress 24.
　あるいは、図６と同様に、第二ヒンジ１９がカバー５から分離できる機能を追加しても構わない。 Alternatively, as in FIG. 6, a function that allows the second hinge 19 to be separated from the cover 5 may be added.
　図９は第一形態でカバー５と双眼レンズ６を上筐体１に収容する方法に関する追加機能の説明図である。同図（１）～（５）は、第一形態でカバー５と双眼レンズ６を上筺体１に収容する方法に関する追加機能の説明図である。 FIG. 9 is an explanatory view of an additional function related to a method of housing the cover 5 and the binocular lens 6 in the upper case 1 in the first embodiment. FIGS. (1) to (5) are explanatory views of additional functions related to a method of housing the cover 5 and the binocular lens 6 in the upper housing 1 in the first embodiment.
　図９（２）に示すように、カバー５を上筐体１に折り畳んだ状態では、第一ヒンジ１６の軸は上筐体１の側面より外側（図の右側）に飛び出している。 As shown in FIG. 9 (2), in the state where the cover 5 is folded in the upper case 1, the axis of the first hinge 16 protrudes outward (right side in the figure) from the side surface of the upper case 1.
　そこで、軸受け１３が左方向にスライドする機能と、溝１８の端に第二のガイド２７を設けることにより、カバー５を左方向にスライドして第一ヒンジ１６の出っ張りをなくすとともに、第二ガイド２７とカバー５がかみ合うことで、カバー５が上筐体１と密着した状態で固定することが可能となる。 Therefore, by providing the second guide 27 at the end of the groove 18 with the function of the bearing 13 sliding to the left, the cover 5 is slid to the left to eliminate the protrusion of the first hinge 16, and the second guide The engagement between the cover 27 and the cover 5 makes it possible to fix the cover 5 in close contact with the upper housing 1.
　図９（４）にはカバー５をスライドした状態での上筐体１とカバー５の斜視図を示す。 FIG. 9 (4) shows a perspective view of the upper housing 1 and the cover 5 in a state where the cover 5 is slid.
　図９（３）の第二ガイド２７の断面（Ｂ－Ｂ’）を図９（５）に示す。第二ガイド２７の断面の先端はかぎ状の構造を有していて、上筐体に対して垂直方向にカバーがはずれない機能を実現できる。 The cross section (B-B ') of the second guide 27 of FIG. 9 (3) is shown in FIG. 9 (5). The tip of the cross section of the second guide 27 has a hook-like structure, and can realize the function of preventing the cover from coming off in the vertical direction with respect to the upper housing.
　図１０（１）には、第二形態における３Ｄ画像表示画面に対して、２Ｄ情報を重ねて表示する方法を示す。同図（１）は、第二形態における３Ｄ画像表示画面に対して２Ｄ情報を重ねて表示する方法を説明する説明図である。同図（２）は、第二形態において２Ｄ画像表示を行う方法を説明する説明図である。 FIG. 10A shows a method of overlapping and displaying 2D information on the 3D image display screen in the second embodiment. The same figure (1) is explanatory drawing explaining the method to overlap and display 2D information with respect to the 3D image display screen in a 2nd form. The figure (2) is explanatory drawing explaining the method to perform 2D image display in a 2nd form.
　例えば、３Ｄ画像表示中にメールや電話を受信したことをユーザに知らせたり、時刻表示など、少ない情報を簡潔にユーザに伝達することが必要な場合には、３Ｄ画面上に２Ｄの情報を重ねて表示する必要がある。このとき、左右画面ともに２Ｄ表示を行うと、ユーザが左右視差を大きく変化させる必要が生じる。そこで、図１０（１）に示すように２Ｄ情報は右（または左）画面のみに情報を表示することによって、ユーザが視差を変えずに２Ｄ情報を容易に読み取ることが可能となる。 For example, when it is necessary to notify the user that a mail or a phone call has been received during 3D image display, or to convey a small amount of information concisely to the user such as time display, 2D information is superimposed on the 3D screen. Need to be displayed. At this time, when 2D display is performed on both the left and right screens, the user needs to largely change the left and right parallax. Therefore, as shown in FIG. 10 (1), by displaying information on the right (or left) screen only, it becomes possible for the user to easily read the 2D information without changing the parallax.
　図１０（２）は、第二形態において２Ｄ画像表示を行う方法である。 FIG. 10 (2) is a method of performing 2D image display in the second embodiment.
　近年、携帯端末装置用の表示素子は高精細化が進み、多量の情報を表示することが可能になったが、携帯端末装置の表示素子で表示した文字や画像は、細かすぎて見にくくなるという課題があった。 In recent years, the display elements for portable terminal devices have become higher definition, and it has become possible to display a large amount of information, but characters and images displayed by the display elements of the portable terminal device are too fine to be seen There was a problem.
　そこで、左画面１１と右画面１０に同一の画像を表示し、３Ｄ表示用双眼レンズを用いて見ることで２Ｄ画像の拡大表示が実現できる。 Then, the same image is displayed on the left screen 11 and the right screen 10, and the enlarged display of the 2D image can be realized by viewing using the 3D display binocular lens.
　このように、本実施の形態１の携帯端末装置により、従来の２Ｄ表示と３Ｄ表示を両立しながら、薄型な電子機器を実現することができる。 As described above, according to the mobile terminal device of the first embodiment, it is possible to realize a thin electronic device while achieving both conventional 2D display and 3D display.
（実施の形態２）
　図１１は本実施の形態２の携帯端末装置の上筐体１の概略斜視構造図を示す。同図（１）は、カバー５の回転前の状態を示す構造図である。同図（２）は、カバー５の回転後の状態を示す構造図である。また、カバー５、双眼レンズ６、第一ヒンジ１６及び第二ヒンジ１９の構造については実施の形態１と同様であり、説明を省略する。 Second Embodiment
FIG. 11 shows a schematic perspective structural view of the upper case 1 of the portable terminal device of the second embodiment. FIG. 1A is a structural view showing a state before the cover 5 is rotated. The figure (2) is a structural diagram which shows the state after rotation of the cover 5. FIG. Further, the structures of the cover 5, the binocular lens 6, the first hinge 16 and the second hinge 19 are the same as in the first embodiment, and the description will be omitted.
　実施の形態１と大きく異なる点は上筐体１の裏面、すなわち第一表示素子２（メインディスプレイ）と反対面に第二表示素子２９（サブディスプレイ）を有する点である。従来の折畳み型携帯電話では上筐体１を閉じた状態でメール受信情報などを知る方法としてサブディスプレイによる表示が一般的である。 A large difference from Embodiment 1 is that the second display element 29 (sub-display) is provided on the back surface of the upper housing 1, that is, the opposite surface to the first display element 2 (main display). In a conventional foldable mobile phone, a display using a sub display is generally used as a method of knowing mail reception information etc. with the upper case 1 closed.
　図１１（１）に示すように、第二表示素子２９と双眼レンズ６の透明な部分が重なるように配置し、さらに、カバー５の中の第二表示素子２９が配置されている部分を透明にすることによって、第一形態、すなわちカバーが折り畳まれた状態でも第二表示素子を利用することが可能となる。 As shown in FIG. 11A, the transparent portions of the second display element 29 and the binocular lens 6 are disposed so as to overlap with each other, and the portion of the cover 5 where the second display element 29 is disposed is transparent. In this way, it is possible to use the second display element even in the first mode, that is, in the state in which the cover is folded.
（実施の形態３）
　図１２は本実施の形態３の携帯端末装置の第二形態における概略斜視構造図を示す。 Third Embodiment
FIG. 12 shows a schematic perspective structural view of a second embodiment of the mobile terminal device of the third embodiment.
　本実施の形態３は、双眼レンズ６と第一表示素子２との間の距離の調整機能を追加したものである。その他の構造については実施の形態１や２と同様のため説明を省略する。 In the third embodiment, an adjustment function of the distance between the binocular lens 6 and the first display element 2 is added. The other structures are the same as in the first and second embodiments, and thus the description thereof is omitted.
　実施の形態１では、第二ヒンジ１９とカバー５は固定されていたが、本実施の形態では図１２に示すように、第二ヒンジ１９をカバー５から分離し、細長い第二の軸受け３０をつけてカバー５に第三のガイド３１を設けることにより、双眼レンズ６とカバー５の距離を伸ばすことが可能となる。ユーザの視力に応じて、双眼レンズの位置の調整を行うことができる。例えば近視の人は、双眼レンズと画面の距離を離したほうが見やすくなる。 In the first embodiment, the second hinge 19 and the cover 5 are fixed, but in the present embodiment, as shown in FIG. 12, the second hinge 19 is separated from the cover 5 and the elongated second bearing 30 is By providing the third guide 31 on the cover 5, it is possible to extend the distance between the binocular lens 6 and the cover 5. The position of the binocular lens can be adjusted according to the user's vision. For example, a person with myopia sees better if the distance between the binocular lens and the screen is greater.
（実施の形態４）
　図１３は本実施の形態４の携帯端末装置の概略斜視構造図を示す。同図（１）は、カバー５の回転前の状態を示す構造図である。同図（２）は、カバー５の回転後の状態を示す構造図である。 Embodiment 4
FIG. 13 is a schematic perspective view of the portable terminal device of the fourth embodiment. FIG. 1A is a structural view showing a state before the cover 5 is rotated. The figure (2) is a structural diagram which shows the state after rotation of the cover 5. FIG.
　本実施の形態３は、立体画像を撮影するための２つの撮像素子（カメラ）３３を追加したものであり、その他の構造については実施の形態１と同様のため説明を省略する。 The third embodiment adds two imaging elements (cameras) 33 for capturing a stereoscopic image, and the other structure is the same as that of the first embodiment, and thus the description thereof is omitted.
　図１３（２）に示すように、２つの撮像素子３３を約５～７ｃｍ程度の距離だけ離し、上筐体１の第一表示素子２と反対面上に配置する。人間の左右の目距離（５～７ｃｍ）を離した２つの撮像素子で画像撮影することで、立体画像の撮影が可能になる。このとき図１３（１）に示すように、双眼レンズ６が折り畳まれた状態で撮像素子と重ならないように、双眼レンズよりも第一ヒンジ１６に近いところに配置する。これにより、撮像素子上に双眼レンズがないことから薄型化が可能となる。カバー５を折り畳んだときの撮像素子上に、カバー上の第二透明部３２を有することにより、双眼レンズ６の収容時も立体画像撮影が可能となる。 As shown in FIG. 13 (2), the two imaging elements 33 are separated by a distance of about 5 to 7 cm, and disposed on the surface opposite to the first display element 2 of the upper housing 1. Taking an image with two imaging elements separated by human left and right eye distance (5 to 7 cm) enables taking a stereoscopic image. At this time, as shown in FIG. 13A, the binocular lens 6 is arranged closer to the first hinge 16 than the binocular lens so as not to overlap with the imaging device in a folded state. As a result, since there is no binocular lens on the imaging device, it is possible to make it thin. By providing the second transparent portion 32 on the cover on the image pickup device when the cover 5 is folded, stereoscopic image shooting can be performed even when the binocular lens 6 is stored.
　なお、携帯端末装置が上筐体１と下筐体３からなる折畳み型の端末の場合は、３Ｄカメラを下筐体３に配置しても構わない。図１４は、折畳み型携帯端末装置の下筐体３に撮像素子３３を２つ配置した例である。 In the case where the portable terminal device is a folded terminal including the upper case 1 and the lower case 3, the 3D camera may be disposed in the lower case 3. FIG. 14 shows an example in which two imaging elements 33 are arranged in the lower case 3 of the folded portable terminal device.
（実施の形態５）
　図１５は本実施の形態５の双眼レンズアダプタの概略構造斜視図を示す。 Fifth Embodiment
FIG. 15 is a schematic structural perspective view of the binocular lens adapter of the fifth embodiment.
　双眼レンズ６やカバー５からなる部品を双眼レンズアダプタ３４として、携帯端末装置３５から着脱可能にしたものを図１５に示す。携帯端末装置３５の表示素子が付いた上筐体１の裏面に軸受け１３を固定することによって、上述の折畳み可能な双眼レンズ６による第二表示モード（３Ｄ表示）が可能となる。固定には例えば両面テープやネジなど用いる。携帯端末装置３５は折畳み型携帯端末である必要はなく、表示素子を有する電子機器であれば構わない。表示素子と反対面の筐体に上記双眼レンズアダプタ３４を固定すればよい。 FIG. 15 shows a component including the binocular lens 6 and the cover 5 as a binocular lens adapter 34, which is detachable from the portable terminal device 35. As shown in FIG. By fixing the bearing 13 to the back surface of the upper housing 1 to which the display element of the portable terminal device 35 is attached, the second display mode (3D display) by the foldable binocular lens 6 described above becomes possible. For example, a double-sided tape or a screw is used for fixing. The portable terminal device 35 does not have to be a folding portable terminal, and may be an electronic device having a display element. The binocular lens adapter 34 may be fixed to the housing opposite to the display element.
