Description

本発明は、表示器保持部品及び携帯電子機器に関し、特に、表示器に埃等が付着するのを防止すると共に表示器を保持する表示器保持部品、及びこの表示器保持部品により表示器が装着されている携帯電子機器、並びに表示器保持部品の組み付け方法に関する。 The present invention relates to a display holding part and a portable electronic device, and more particularly to a display holding part that prevents dust from adhering to the display and holds the display, and the display is mounted by the display holding part. The present invention relates to a portable electronic device and a method for assembling a display holding component.

従来、携帯電子機器の表示器を保持する表示器保持部品が知られている。携帯電子機器である携帯電話装置には、例えば、メインとサブの２個の表示器を備えたものがあり、サブ表示器は、筐体の外ケース内面に直接取り付けられている。このサブ表示器の表示面に塵埃等が付着するのを防止するため、サブ表示器をスポンジ等の弾性部材により形成したシートを介して筐体に取り付けている。
つまり、例えば、液晶ディスプレイ（ＬｉｑｕｉｄＣｒｙｓｔａｌＤｉｓｐｌａｙ：ＬＣＤ）からなるサブ表示器に接触する筐体側にシートを貼り付けて、サブ表示器と筐体の間に生じる隙間を埋めることにより、筐体内部においてサブ表示器の表示面に塵埃等が入り込むのを防止している。 Conventionally, a display holding component for holding a display of a portable electronic device is known. Some mobile phone devices that are portable electronic devices include, for example, a main display and a sub display, and the sub display is directly attached to the inner surface of the outer case of the housing. In order to prevent dust and the like from adhering to the display surface of the sub display, the sub display is attached to the housing via a sheet formed of an elastic member such as a sponge.
That is, for example, by sticking a sheet on the housing side that comes into contact with a sub-display composed of a liquid crystal display (Liquid Crystal Display: LCD) and filling a gap generated between the sub-display and the housing, Dust and the like are prevented from entering the display surface of the sub display.

また、サブ表示器の筐体への固定は、例えば、サブ表示器の表示面を形成するガラス面の周辺を囲うように装着してサブ表示器を保持する、例えば、プラスチックホルダを介して、即ち、サブ表示器を保持したプラスチックホルダを筐体に固定して行っている。
このような、表示器を保持したホルダを用いて筐体に表示器を装着するものとして、例えば、「ＬＣＤ表示器取付け構造」（特許文献１参照）がある。 In addition, the sub-display is fixed to the housing, for example, by holding the sub-display so as to surround the periphery of the glass surface forming the display surface of the sub-display, for example, via a plastic holder, That is, the plastic holder holding the sub display is fixed to the housing.
For example, there is “LCD display mounting structure” (see Patent Document 1) for mounting a display on a housing using such a holder holding the display.

ところで、従来の表示器を装着する構造において、表示器の表示面に塵埃等が入り込むのを防止する効果を更に高めるために、筐体に接触するホルダの表面の表示器の周囲に、突条を設け、或いはその突条を二重に配置したものが考えられる。
特開平０９−２８３９５０号公報 By the way, in the structure in which the conventional display is mounted, in order to further enhance the effect of preventing dust and the like from entering the display surface of the display, a protrusion is formed around the display on the surface of the holder that contacts the housing. It is conceivable that the ridges are provided or the ridges are arranged twice.

本発明によれば、部品点数を減少させつつ防塵効果を高めることができる。 According to the present invention, it is possible to enhance the dustproof effect while reducing the number of parts.

以下、本発明を実施するための最良の形態について図面を参照して説明する。
図１は、本発明の一実施の形態に係るホルダを示し、（ａ）は表面側の斜視図、（ｂ）は裏面側の斜視図である。図２は、図１（ａ）のホルダを示し、（ａ）はＡ−Ａ線に沿う断面図、（ｂ）はＢ−Ｂ線に沿う断面図である。
図１及び図２に示すように、ホルダ（表示器保持部品）１０は、枠部１１に囲まれた矩形状の開口１２を有する枠形枠状体からなり、ゴム、スポンジ、軟質樹脂等の弾性部材を一体成型することにより形成されている。このホルダ１０には、後述する薄板状の表示器１８（図３参照）が組み込まれ保持される。 The best mode for carrying out the present invention will be described below with reference to the drawings.
1A and 1B show a holder according to an embodiment of the present invention, in which FIG. 1A is a front perspective view, and FIG. 1B is a rear perspective view. 2A and 2B show the holder of FIG. 1A, in which FIG. 2A is a sectional view taken along the line AA, and FIG. 2B is a sectional view taken along the line BB.
As shown in FIGS. 1 and 2, the holder (display holding part) 10 is formed of a frame-shaped frame body having a rectangular opening 12 surrounded by a frame portion 11, and is made of rubber, sponge, soft resin, or the like. It is formed by integrally molding an elastic member. The holder 10 incorporates and holds a thin plate display 18 (see FIG. 3), which will be described later.

枠部１１は、少なくとも表示器１８の厚み（肉厚）に相当する厚み（表裏面幅）を有しており、表面１１ａ（第２の面）側には、一方の長辺部にカバー部１３（図１（ａ）参照）が、他方の長辺部及び両短辺部に保持壁１４（図１（ａ）参照）が、裏面１１ｂ（第１の面）側には、他方の長辺部に舌部（背面保持部）１５（図１（ｂ）参照）を、それぞれ有している。つまり、枠部１１は、保持されるべき表示器１８の周縁部を覆って表示面１８ａを露出させる開口１２が形成される保持壁１４を有する。また、枠部１１は、裏面１１ｂ表示器１８の外周を囲う壁状の側壁１１ｃを有するように形成されており、カバー部１３裏面側の側壁の中央部分が、配線部材を位置させるために切り欠かれている（図１（ｂ）参照）。 The frame portion 11 has a thickness (front and back surface width) corresponding to at least the thickness (thickness) of the display 18, and on the front surface 11 a (second surface) side, one long side portion has a cover portion. 13 (see FIG. 1A) is the other long side portion and both short side portions are holding walls 14 (see FIG. 1A), and the back surface 11b (first surface) side is the other long side. Each side has a tongue (back holding portion) 15 (see FIG. 1B). That is, the frame part 11 has the holding wall 14 in which the opening 12 that covers the peripheral part of the display 18 to be held and exposes the display surface 18a is formed. Further, the frame portion 11 is formed to have a wall-like side wall 11c surrounding the outer periphery of the back surface 11b indicator 18, and the central portion of the side wall on the back surface side of the cover portion 13 is cut to position the wiring member. It is missing (see FIG. 1 (b)).

開口１２は、表示器１８の表示面１８ａを露出させることができる、表示面１８ａの形状に対応した開口形状を有している。カバー部１３は、後述する外部配線接続部１９を覆うことができる幅が広い薄板状に形成されている（図１参照）。保持壁１４は、カバー部１３に連続すると共に枠部１１の側壁１１ｃに対し内向きフランジ状に形成されている（図１，２参照）。
舌部１５は、他方の長辺部から延び出て先端がカバー部１３近傍に達する矩形状を有しており、一方の長辺部（即ち、カバー部１３）側及び両短辺部側の３辺が枠部１１から切り離され離間している（図１，２参照）。また、舌部１５と枠部１１の連結部となる枠部１１の他方の長辺部Ｈが、枠部１１に対し曲げ易くなるように、舌部１５における他方の長辺部Ｈ以外の部分に比べ薄肉状態に形成されている（図１，２参照）。 The opening 12 has an opening shape that can expose the display surface 18a of the display 18 and that corresponds to the shape of the display surface 18a. The cover portion 13 is formed in a thin plate shape having a wide width that can cover an external wiring connection portion 19 to be described later (see FIG. 1). The holding wall 14 is continuous with the cover portion 13 and is formed in an inward flange shape with respect to the side wall 11c of the frame portion 11 (see FIGS. 1 and 2).
The tongue portion 15 has a rectangular shape that extends from the other long side portion and has a tip that reaches the vicinity of the cover portion 13, and is provided on one long side portion (that is, the cover portion 13) side and both short side portion sides. Three sides are separated from the frame 11 and separated (see FIGS. 1 and 2). Further, a portion of the tongue portion 15 other than the other long side portion H so that the other long side portion H of the frame portion 11 serving as a connecting portion between the tongue portion 15 and the frame portion 11 is easily bent with respect to the frame portion 11. Compared to FIG. 1, it is formed in a thin state (see FIGS. 1 and 2).

つまり、舌部１５は、枠部１１の特に側壁１１ｃ一部に連続する連結部をもって連続して形成されるとともに、この連結部を除き枠部１１から切り離されて、開口周縁部（保持壁１４）から表示器を保持可能な程度の空隙を持って、枠部１１の第１の面に対向するように、かつ、開口１２の範囲内に位置する形状を有して形成されており、表示面１８ａの背面側に位置している。このため、他方の長辺部Ｈを基部１５ａとして一方の長辺部側が自由端１５ｂとなり、基部１５ａを支点に屈曲させて自由端１５ｂを表面１１ａ側及び裏面１１ｂ側に自由に変位させることができる。
このように、枠部１１は、保持壁１４により、保持した表示器１８の表示面１８ａ側周縁部を覆うと共に、表示面１８ａを露出させる開口１２を形成しており、表面１１ａ側と裏面１１ｂ側の間、即ち、カバー部１３及び保持壁１４と舌部１５の間の空隙に、表示器１８を挟み込むように収納し保持することができる。 That is, the tongue portion 15 is formed continuously with a connecting portion that is continuous with a part of the side wall 11c of the frame portion 11, and is separated from the frame portion 11 except for this connecting portion, and the opening peripheral portion (the holding wall 14). ) With a gap that can hold the display device, facing the first surface of the frame 11 and having a shape located within the range of the opening 12. It is located on the back side of the surface 18a. For this reason, the other long side H is the base 15a, the one long side becomes the free end 15b, the base 15a is bent around the fulcrum, and the free end 15b can be freely displaced to the front surface 11a side and the back surface 11b side. it can.
As described above, the frame portion 11 covers the display surface 18a side peripheral portion of the display 18 held by the holding wall 14 and forms the opening 12 that exposes the display surface 18a. The front surface 11a side and the back surface 11b are formed. The indicator 18 can be stored and held so as to be sandwiched between the sides, that is, in the gap between the cover portion 13 and the holding wall 14 and the tongue portion 15.

また、ホルダ１０には、枠部１１の表面１１ａ側に、開口１２を取り囲むように全周にわたって形成されると共に、所定間隔を有して内外二重に配置された、突条（第１突条）１６ａと突条（第２突条）１６ｂが突設されている。２本の突条１６ａ，１６ｂは、それぞれ弾性部材からなる、枠部１１の表示器視認方向に向けて突出する細い糸状のリブ形に形成されている。枠部１１には、他方の長辺部（即ち、舌部１５の基部１５ａ側）の離間する２箇所と、各短辺部の一方の長辺部（即ち、カバー部１３）側端の２箇所の計４箇所に、爪受け部（係止固定部）１７が設けられている。各爪受け部１７は、裏面１１ｂ側に開口する各辺に沿った長穴状に形成されている（図１（ｂ）参照）。 Further, the holder 10 is formed on the surface 11a side of the frame portion 11 over the entire circumference so as to surround the opening 12, and is arranged in a double space with a predetermined interval (first protrusion). Article 16) and protrusion (second protrusion) 16b are provided. The two ridges 16a and 16b are each formed into a thin thread-like rib shape made of an elastic member and projecting toward the indicator viewing direction of the frame portion 11. The frame portion 11 includes two spaced apart portions on the other long side portion (that is, the base portion 15a side of the tongue portion 15), and two ends on one long side portion (that is, the cover portion 13) side end of each short side portion. Claw receiving portions (locking fixing portions) 17 are provided at a total of four locations. Each claw receiving portion 17 is formed in a long hole shape along each side opened to the back surface 11b side (see FIG. 1B).

このホルダ１０は、例えば、金型成型により形成することができるが、成型に際しアンダーカット部となる箇所を極力減らしているので、生産性の向上を図ることができる。つまり、ホルダ１０にあっては、成型に際しアンダーカット部となる箇所が、舌部１５の基部１５ａのみであり、保持壁１４が形成された、舌部１５の一方の長辺部（即ち、カバー部１３）側及び両短辺部側の３辺部分は、裏面１１ｂ側が空間となっている（図１，２参照）。 The holder 10 can be formed by, for example, mold molding. However, since the number of locations serving as undercut portions is reduced as much as possible, productivity can be improved. In other words, in the holder 10, only the base portion 15 a of the tongue portion 15 is the undercut portion when molding, and one long side portion of the tongue portion 15 (that is, the cover 15) in which the holding wall 14 is formed. The three sides of the portion 13) side and both short side portions are spaces on the back surface 11b side (see FIGS. 1 and 2).

また、舌部１５は、開口１２の範囲内に位置しているので、ホルダ１０の金型設計に際し抜き構造を容易に形成することができる。また、カバー部１３裏面側で切り欠かれた枠部１１の離間距離は、舌部１５の横幅（自由端１５ｂ側辺の幅）と略同一に形成されており（図１（ｂ）参照）、ホルダ１０の金型設計に際し効果的である。更に、枠部１１は、舌部１５が形成されていない部分が、保持壁１４を有するのみのＬ字状断面形状を有している（図２参照）ので、ホルダ１０の金型設計に際し抜き構造を容易に形成することができる。
なお、表示器１８を保持するホルダ１０が、基部１５ａで枠部１１に接続し、基部１５ａ以外は枠部１１から切り離された舌部１５を有することにより、金型によるホルダ１０の成型後、舌部１５をめくって金型からホルダ１０を取り出すことができる。 Further, since the tongue portion 15 is located within the range of the opening 12, a punching structure can be easily formed when designing the mold of the holder 10. Further, the separation distance of the frame portion 11 cut out on the back surface side of the cover portion 13 is formed substantially the same as the lateral width of the tongue portion 15 (the width of the free end 15b side) (see FIG. 1B). This is effective in designing the mold of the holder 10. Furthermore, since the frame portion 11 has an L-shaped cross-sectional shape in which the tongue portion 15 is not formed only having the holding wall 14 (see FIG. 2), the frame portion 11 is removed when designing the mold of the holder 10. The structure can be easily formed.
In addition, after the holder 10 holding the indicator 18 is connected to the frame portion 11 at the base portion 15a and has the tongue portion 15 separated from the frame portion 11 except for the base portion 15a, the holder 10 is molded by a mold, The holder 10 can be removed from the mold by turning the tongue 15.

図３は、図１のホルダに保持される表示器を示し、（ａ）は正面図、（ｂ）は斜視図である。図３に示すように、ホルダ１０に保持される表示器１８は、液晶ディスプレイ（ＬＣＤ）や有機発光ダイオード（ＯｒｇａｎｉｃＬｉｇｈｔＥｍｉｔｔｉｎｇＤｉｏｄｅ：ＯＬＥＤ）等からなる。表示器１８の一方の長辺部側には、表示器１８に対し給電及び信号導通を行う外部配線接続部１９が形成されており、外部配線接続部１９には、フレキシブルプリント配線板（ＦｌｅｘｉｂｌｅＰｒｉｎｔｅｄＣｉｒｃｕｉｔ：ＦＰＣ）２０が接続されている。外部配線接続部１９は、表示面１８ａの外形線（短辺）を延長して形成した長方形状を有している。なお、表示器１８には、自発光素子型の表示器（ＯＬＥＤなど）、或いはバックライトを備えた表示器（ＬＣＤなど）が用いられる。 3A and 3B show the display device held by the holder of FIG. 1, wherein FIG. 3A is a front view and FIG. 3B is a perspective view. As shown in FIG. 3, the display 18 held by the holder 10 includes a liquid crystal display (LCD), an organic light emitting diode (OLED), or the like. On one long side of the display 18, an external wiring connection portion 19 for supplying power and conducting signals to the display 18 is formed. The external wiring connection portion 19 has a flexible printed wiring board (Flexible Printed). Circuit (FPC) 20 is connected. The external wiring connection portion 19 has a rectangular shape formed by extending the outline (short side) of the display surface 18a. As the display 18, a self-luminous element type display (OLED or the like) or a display (LCD or the like) provided with a backlight is used.

図４は、図１のホルダに図３の表示器を装着した状態を示し、（ａ）は表面側の斜視図、（ｂ）は裏面側の斜視図である。図４に示すように、ホルダ１０に表示器１８を装着する（（ａ）参照）場合、裏返しにしたホルダ１０の舌部１５をめくって上方に引き上げ（（ｂ）矢印参照）、その状態を保持したまま、裏返しにしてＦＰＣ２０が取り付けられていない側を先方に向けた表示器１８を、カバー部１３側から舌部１５下方に挿入する（（ｂ）白抜き矢印参照）。 4 shows a state in which the display of FIG. 3 is mounted on the holder of FIG. 1, wherein (a) is a perspective view of the front surface side, and (b) is a perspective view of the back surface side. As shown in FIG. 4, when the indicator 18 is mounted on the holder 10 (see (a)), the tongue 15 of the holder 10 turned upside down is turned up and pulled upward (see (b) arrow), While being held, the display 18 is turned upside down and the side to which the FPC 20 is not attached is directed forward from the cover 13 side to the lower side of the tongue 15 (see (b) white arrow).

挿入した表示器１８を、開口１２の上方から開口１２を塞ぐように枠部１１に嵌め込んで、枠部１１に組み込む（（ｂ）参照）。枠部１１に表示器１８を組み込んだ後に、舌部１５の保持を解除すると、弾性部材からなる舌部１５は、直ぐに元の状態に復帰して表示器１８の裏面１８ｂに接触した状態になる。このようにして、容易に表示器１８をホルダ１０に取り付けることが可能となっている。 The inserted indicator 18 is fitted into the frame portion 11 so as to close the opening 12 from above the opening 12, and is incorporated into the frame portion 11 (see (b)). When the holding of the tongue portion 15 is released after the display device 18 is incorporated into the frame portion 11, the tongue portion 15 made of an elastic member immediately returns to the original state and comes into contact with the back surface 18 b of the display device 18. . In this way, the display 18 can be easily attached to the holder 10.

図５は、表示器装着状態のホルダを示し、（ａ）は図４（ａ）の断面による説明図、（ｂ）は（ａ）の保持壁を拡大した説明図である。図５に示すように、ホルダ１０に装着された表示器１８は、表示面１８ａ側をカバー部１３及び保持壁１４に接触させると共に、裏面１８ｂ側を舌部１５に接触させており、カバー部１３及び保持壁１４と舌部１５によって表裏面両側から挟み込まれた状態になる（（ａ）参照）。この状態で、表示器１８は、表示面１８ａの全域を開口１２から露出させる（図３（ａ）参照）と共に、裏面１８ｂの略全域が舌部１５に覆われる（図３（ｂ）参照）。 FIGS. 5A and 5B show the holder with the display mounted, where FIG. 5A is an explanatory view of the cross section of FIG. 4A and FIG. 5B is an enlarged view of the holding wall of FIG. As shown in FIG. 5, the indicator 18 attached to the holder 10 has the display surface 18 a side in contact with the cover portion 13 and the holding wall 14, and the back surface 18 b side in contact with the tongue portion 15. 13 and the holding wall 14 and the tongue 15 are sandwiched from both the front and back surfaces (see (a)). In this state, the display 18 exposes the entire area of the display surface 18a from the opening 12 (see FIG. 3A), and substantially the entire area of the back surface 18b is covered with the tongue 15 (see FIG. 3B). .

保持壁１４には、２本の突条１６ａ，１６ｂが形成されているが、保持壁１４の先端側、即ち、枠部１１の内側に位置する突条１６ａと、保持壁１４の基部側、即ち、枠部１１の外側に位置する突条１６ｂは、枠部１１の表面１１ａからの高さが異なっている（（ｂ）参照）。
つまり、例えば、突条１６ｂを、突条１６ａより高さａだけ低く形成することにより、２本の突条１６ａ，１６ｂは、突出高さを異ならせている。また、高さａは、０．０５ｍから０．３ｍｍの範囲内であれば良く、例えば、約０．１ｍｍに形成することが望ましい。 Two ridges 16a and 16b are formed on the holding wall 14, but the tip 16a of the holding wall 14, that is, the inner side of the frame portion 11, the ridge 16a and the base side of the holding wall 14, That is, the protrusion 16b located outside the frame part 11 has a different height from the surface 11a of the frame part 11 (see (b)).
That is, for example, the protrusion 16b is formed to have a height a lower than the protrusion 16a, whereby the two protrusions 16a and 16b have different protrusion heights. The height a may be in the range of 0.05 m to 0.3 mm, and for example, it is desirable to form the height a to about 0.1 mm.

また、保持壁１４の先端側、即ち、枠部１１の内側に位置する突条１６ａの下部には、可撓部１４ａが形成されている。この可撓部１４ａは、裏面１１ｂ（第１の面）における突条１６ａが形成される位置に対応する位置において、枠部１１の裏面１１ｂ側と表面１１ａ側との間の厚さについて開口１２側を薄く、枠部１１の外周側を厚くなるよう形成されている。この可撓部１４ａは、少なくとも突条１６ａが位置する部分を含んでおり、突条１６ａの突出先端に対し表示器下向きの押圧力が付加された場合、突条１６ａを容易に開口の中央向き方向に横倒しに倒れ込ませる。 In addition, a flexible portion 14 a is formed on the distal end side of the holding wall 14, that is, on the lower portion of the protrusion 16 a located on the inner side of the frame portion 11. The flexible portion 14a has an opening 12 with respect to the thickness between the back surface 11b side and the front surface 11a side of the frame portion 11 at a position corresponding to the position at which the protrusion 16a is formed on the back surface 11b (first surface). It is formed so that the side is thin and the outer peripheral side of the frame portion 11 is thick. The flexible portion 14a includes at least a portion where the protrusion 16a is positioned. When a downward pressing force is applied to the protrusion tip of the protrusion 16a, the protrusion 16a is easily oriented toward the center of the opening. Let them lie down sideways.

この可撓部１４ａを形成するためには、保持壁１４の先端側が傾斜面或いは段差部等により撓み易い形状になっていればよい。更には、内部を中空にしても撓み易いので同様の効果が得られる。つまり、可撓部１４ａは、裏面１１ｂにおいて一段段差が付けられて薄くなっていたり、開口縁の突条１６ａの直下に中空構造にしたりして、保持壁１４における他の部位よりも薄肉加工して軟性を持たせてあれば、突条１６ａが押圧されたときに撓み易くなるので、ケース内側の窓部周縁への密着を均一にし易い。
突条は、可撓部１４ａの上方に位置する枠部１１内側の突条（第１突条）１６ａと、突条１６ａの外側に位置して開口１２を囲う枠部１１外側の突条（第２突条）１６ｂの二重に形成されている。 In order to form the flexible portion 14a, it is sufficient that the distal end side of the holding wall 14 has a shape that can be easily bent by an inclined surface or a stepped portion. Furthermore, even if the inside is hollow, it is easy to bend, so the same effect can be obtained. That is, the flexible portion 14a is thinned with a step on the back surface 11b, or has a hollow structure immediately below the protrusion 16a at the opening edge, so that the flexible portion 14a is processed to be thinner than other portions of the holding wall 14. If the ridge 16a is pressed, it is easy to bend when the ridge 16a is pressed, so that it is easy to make the contact with the peripheral edge of the window inside the case uniform.
The ridges are ridges (first ridges) 16a inside the frame part 11 located above the flexible part 14a, and ridges outside the frame part 11 that are located outside the ridges 16a and surround the opening 12 ( (Second protrusion) 16b is formed in double.

Two sub-displays comprising the display 18 (see FIG. 3) are provided.

図７に示すように、第１筐体２２は、メイン表示器２４が装着される下ケース２５、補強板金（板金部品）２６、メイン基板２７、サブ表示器１８を保持したホルダ１０が装着される上ケース（外部ケース）２８、及び化粧パネル（加飾プレート）２９を有しており、これら各部材を記載順に積み重ねて組み立てられている。下ケース２５には、ＳＯＢ（ＳｙｓｔｅｍＯｎＢｏａｒｄ）基板（図示略）を組み込んだヒンジ部３１が設けられている。 As shown in FIG. 7, the first casing 22 is mounted with a lower case 25 to which the main display 24 is mounted, a reinforcing sheet metal (sheet metal part) 26, a main board 27, and a holder 10 that holds the sub display 18. The upper case (outer case) 28 and the decorative panel (decorating plate) 29 are assembled, and these members are assembled in the order described. The lower case 25 is provided with a hinge portion 31 incorporating an SOB (System On Board) substrate (not shown).

プレス成形により形成される補強板金２６は、薄板状のメイン表示器２４を補強すると共に表示器の静電気対策を兼ねており、ホルダ１０の枠部１１を取り付けて位置決め固定するための爪（係止手段）２６ａを４個有している。この爪２６ａは、例えば、板金からの切り起こしにより別部品を設けることなく形成され、枠部１１に４箇所設けられた爪受け部１７（図１（ｂ）参照）に挿入係止する。 The reinforcing sheet metal 26 formed by press molding reinforces the thin main display 24 and also serves as a countermeasure against static electricity of the display, and is a claw (locking) for attaching and fixing the frame portion 11 of the holder 10. Means) It has four 26a. The claw 26a is formed without being provided with a separate part by, for example, cutting and raising from the sheet metal, and is inserted into and locked to the claw receiving portions 17 (see FIG. 1B) provided at four locations on the frame portion 11.

メイン基板２７には、メイン表示器２４の駆動用デバイス等（図示しない）が形成されており、上ケース２８と上ケース２８の外表面に取り付けられる化粧パネル２９には、サブ表示器１８の表示面１８ａを露出させる開口２８ａ，２９ａが開けられている。化粧パネル２９の開口２９ａには、アクリル樹脂等の透明部材からなるウインドパネル３２が装着される。
第２筐体２３は、駆動用のバッテリ（図示しない）が装着された後に下ケース３４の蓋をするバッテリケース３３、基板等（図示しない）が装着される下ケース３４、及び操作キー（図示しない）が装着される上ケース３５を有しており、これら各部材を記載順に積み重ねて組み立てられている。下ケース３４と上ケース３５は、ヒンジ部３１が取り付けられるヒンジ受け部３４ａ，３５ａを有している。 The main board 27 is formed with a device for driving the main display 24 and the like (not shown), and the decorative panel 29 attached to the outer surface of the upper case 28 and the upper case 28 has a display of the sub display 18. Openings 28a and 29a for exposing the surface 18a are opened. A wind panel 32 made of a transparent member such as acrylic resin is attached to the opening 29a of the decorative panel 29.
The second housing 23 includes a battery case 33 that covers the lower case 34 after a driving battery (not shown) is attached, a lower case 34 to which a substrate or the like (not shown) is attached, and operation keys (not shown). No) is mounted, and these members are assembled in the order described. The lower case 34 and the upper case 35 have hinge receiving portions 34a and 35a to which the hinge portion 31 is attached.

図８は、補助板金装着後の第１筐体の分解構成図である。図８に示すように、下ケース２５に補助板金２６の装着されたメイン表示器２４を取り付けた後、サブ表示器１８をホルダ１０に装着して、サブ表示器１８を保持したホルダ１０を補助板金２６に取り付ける。補助板金２６にホルダ１０を取り付けた後、補助板金２６の上にメイン基板２７を配置する。ホルダ１０から露出するサブ表示器１８のＦＰＣ２０は、メイン基板２７のコネクタ２７ａに接続される。このＦＰＣ２０を介して、メイン基板２７からサブ表示器１８へ給電及び信号導通が行われる。 FIG. 8 is an exploded configuration diagram of the first housing after the auxiliary sheet metal is mounted. As shown in FIG. 8, after attaching the main indicator 24 with the auxiliary sheet metal 26 attached to the lower case 25, the sub indicator 18 is attached to the holder 10 to assist the holder 10 holding the sub indicator 18. Attach to sheet metal 26. After the holder 10 is attached to the auxiliary sheet metal 26, the main board 27 is disposed on the auxiliary sheet metal 26. The FPC 20 of the sub display 18 exposed from the holder 10 is connected to the connector 27 a of the main board 27. Power supply and signal conduction are performed from the main board 27 to the sub display 18 via the FPC 20.

メイン基板２７を配置した後、メイン基板２７、サブ表示器１８を保持したホルダ１０、及び補助板金２６を覆うように、下ケース２５に上ケース２８を取り付ける。上ケース２８の外表面には化粧パネル２９が取り付けられており、化粧パネル２９の開口２９ａに嵌め込んだ透明なウインドパネル３２により、上ケース２８の開口２８ａから露出させたサブ表示器１８の表示面１８ａが覆われる。
図９は、ホルダの装着について説明し、（ａ）はホルダ取り付け前の斜視図、（ｂ）はホルダ取り付け後の斜視図である。図９に示すように、第１筐体２２の下ケース２５にメイン基板２７と共に組み込まれた補強板金２６は、メイン基板２７に設けられたホルダ１０を配置するための空間から、４個の爪２６ａを露出させている（（ａ）参照）。 After the main board 27 is disposed, the upper case 28 is attached to the lower case 25 so as to cover the main board 27, the holder 10 holding the sub display 18, and the auxiliary sheet metal 26. A decorative panel 29 is attached to the outer surface of the upper case 28, and the display of the sub-display 18 exposed from the opening 28 a of the upper case 28 by a transparent wind panel 32 fitted into the opening 29 a of the decorative panel 29. The surface 18a is covered.
9A and 9B illustrate mounting of the holder. FIG. 9A is a perspective view before attaching the holder, and FIG. 9B is a perspective view after attaching the holder. As shown in FIG. 9, the reinforcing sheet metal 26 incorporated in the lower case 25 of the first housing 22 together with the main board 27 has four claws from the space for arranging the holder 10 provided on the main board 27. 26a is exposed (see (a)).

この４個の爪２６ａに、枠部１１の４箇所の爪受け部１７をそれぞれ位置させて、補強板金２６にホルダ１０を載置し、爪受け部１７に爪２６ａを軽く圧入して嵌合状態にする。なお、爪２６ａの長さ（高さ）は、爪受け部１７の深さよりわずかに短く構成してあり、爪２６ａは爪受け部１７を貫通することなく、爪受け部１７内に位置する。これにより、サブ表示器１８を保持したホルダ１０は、補強板金２６に位置決め固定され、表示面１８ａを上に向けた状態で下ケース２５に装着される（（ｂ）参照）。
つまり、メイン表示器２４の表示面の背面側に配置された補強板金２６に、表示面背面側方向に突出させて爪２６ａを形成し、この爪２６ａを爪受け部１７に係止させて、補強板金２６にホルダ１０を固定する。 Four claw receiving portions 17 of the frame portion 11 are respectively positioned on the four claws 26 a, the holder 10 is placed on the reinforcing sheet metal 26, and the claw 26 a is lightly press-fitted into the claw receiving portion 17. Put it in a state. The length (height) of the claw 26 a is configured to be slightly shorter than the depth of the claw receiving portion 17, and the claw 26 a is positioned in the claw receiving portion 17 without penetrating the claw receiving portion 17. Thereby, the holder 10 holding the sub-display 18 is positioned and fixed to the reinforcing sheet metal 26, and is mounted on the lower case 25 with the display surface 18a facing upward (see (b)).
That is, the reinforcing sheet metal 26 disposed on the back side of the display surface of the main display 24 is protruded in the direction toward the back side of the display surface to form the claw 26a, and the claw 26a is engaged with the claw receiving portion 17, The holder 10 is fixed to the reinforcing sheet metal 26.

図１０は、表示器を保持したホルダのケース装着状態を示し、（ａ）は斜視断面図、（ｂ）は拡大断面図である。図１０に示すように、サブ表示器１８を保持したホルダ１０は、舌部１５を補強板金２６に接触させて第１筐体２２の上ケース２８に組み込まれており（（ａ），（ｂ）参照）、上ケース２８の開口２８ａから露出するサブ表示器１８の表示面１８ａは、ウインドパネル３２に覆われている。このように、サブ表示器１８は、表示面、その裏面、さらには側面という全方位に対してホルダ１０という緩衝材にて囲まれる状態で組み込まれることとなり、全方位への衝撃に対して強くすることができる。 10A and 10B show a case mounting state of the holder holding the display, where FIG. 10A is a perspective sectional view and FIG. 10B is an enlarged sectional view. As shown in FIG. 10, the holder 10 holding the sub-display 18 is incorporated in the upper case 28 of the first housing 22 with the tongue portion 15 in contact with the reinforcing sheet metal 26 ((a), (b The display surface 18a of the sub-display 18 exposed from the opening 28a of the upper case 28 is covered with the wind panel 32. Thus, the sub-display 18 is incorporated in a state surrounded by the cushioning material called the holder 10 with respect to all directions of the display surface, its back surface, and further the side surfaces, and is strong against impacts in all directions. can do.

図１１は、第１筐体の上ケースを内面側から見た斜視図である。図１１に示すように、第１筐体２２の上ケース２８には、開口２８ａにウインドパネル３２が取り付けられている。この上ケース２８を、ウインドパネル３２がサブ表示器１８の表示面１８ａを覆うように、下ケース２５に装着する。上ケース２８を下ケース２５に装着することにより、上ケース２８の開口２８ａ周辺の内面Ｎには、ホルダ１０の枠部１１が圧着した状態になり、枠部１１によって、サブ表示器１８の表示面１８ａは上ケース２８の内面Ｎとの間で隙間なく密閉される。従って、ホルダ１０により、上ケース２８の内面Ｎとサブ表示器１８の間から塵埃が入り込むのを阻止して、表示面１８ａに塵埃が付着するのを防止することができる。特に、ホルダ１０の圧着される開口２８ａ周縁の内面Ｎは、凹凸のない平面に構成されており、密閉性が高められている。 FIG. 11 is a perspective view of the upper case of the first housing as viewed from the inner surface side. As shown in FIG. 11, a wind panel 32 is attached to the upper case 28 of the first housing 22 in the opening 28a. The upper case 28 is attached to the lower case 25 so that the window panel 32 covers the display surface 18a of the sub display 18. By attaching the upper case 28 to the lower case 25, the frame portion 11 of the holder 10 is pressed against the inner surface N around the opening 28 a of the upper case 28, and the frame portion 11 displays the display of the sub display 18. The surface 18 a is sealed without a gap between the surface 18 a and the inner surface N of the upper case 28. Therefore, the holder 10 can prevent dust from entering between the inner surface N of the upper case 28 and the sub-display 18 and prevent dust from adhering to the display surface 18a. In particular, the inner surface N of the periphery of the opening 28a to which the holder 10 is pressure-bonded is configured to be a flat surface without unevenness, and the sealing performance is enhanced.

つまり、サブ表示器１８を保持したホルダ１０が、上ケース２８に組み込まれる場合、保持壁１４に形成された２本の突条１６ａ，１６ｂは、高い方、即ち、突条１６ａから先に上ケース２８の内面に接触し、続けて、低い方、即ち、突条１６ｂが上ケース２８の内面に接触することになる。このとき、先に上ケース２８の内面に接触する突条１６ａは、可撓部１４ａにより、容易に横倒し状態に変形するので、突条が接触する筐体の内圧が過度に高くなることはない。更に、筐体の内圧を高めることなく、突条１６ｂとも十分に密着した状態になる。 That is, when the holder 10 holding the sub-indicator 18 is incorporated in the upper case 28, the two ridges 16a and 16b formed on the holding wall 14 are higher, that is, the ridges 16a are moved upward first. The inner surface of the case 28 comes into contact with the lower one, that is, the protrusion 16b comes into contact with the inner surface of the upper case 28. At this time, the ridge 16a that first contacts the inner surface of the upper case 28 is easily laid down by the flexible portion 14a, so that the internal pressure of the casing that the ridge contacts does not become excessively high. . Furthermore, it will be in the state contact | adhered enough with the protrusion 16b, without raising the internal pressure of a housing | casing.

従って、２重の突条１６ａ，１６ｂを備えたホルダ１０は、少なくとも突条１６ａが変位変形して上ケース２８の内面に密着した状態になり、更に、突条１６ｂが上ケース２８の内面に接触する状態になって、上ケース２８との間にサブ表示器１８の表示面１８ａを密封することができる。このため、ホルダ１０により、防塵・防水効果が飛躍的に向上し、上ケース２８の内面とサブ表示器１８の間から塵埃が入り込むのを阻止して、表示面１８ａに塵埃が付着するのを防止することができる。 Accordingly, in the holder 10 provided with the double ridges 16a and 16b, at least the ridge 16a is displaced and deformed so as to be in close contact with the inner surface of the upper case 28, and further, the ridge 16b is attached to the inner surface of the upper case 28. The display surface 18 a of the sub display 18 can be sealed between the upper case 28 and the upper case 28. For this reason, the holder 10 dramatically improves the dustproof / waterproof effect, prevents dust from entering between the inner surface of the upper case 28 and the sub-display 18, and prevents the dust from adhering to the display surface 18a. Can be prevented.

このように、ホルダ１０に保持された表示器１８は、表示器１８を、表示器１８の表裏面両側から挟み込む弾性部材からなるホルダ１０に装着し保持する工程と、表示器１８を保持するホルダ１０を、表示器１８の裏面１８ｂ側に位置する筐体構成部品である補強板金２６に位置決め固定する工程と、表示器１８の裏面１８ｂ側に位置決め固定したホルダ１０を、窓部３２が装着される上ケース２８の内面に突条１６ａ，１６ｂを押圧状態に接触させて筐体内に組み込む工程とを経て、携帯電子機器である携帯電話装置２１に組み付けられる。 As described above, the display 18 held by the holder 10 includes a step of attaching and holding the display 18 to the holder 10 made of an elastic member that is sandwiched from both the front and back sides of the display 18 and a holder for holding the display 18. 10 is positioned and fixed to a reinforcing sheet metal 26 which is a casing component located on the back surface 18b side of the display 18, and the holder 10 which is positioned and fixed on the back surface 18b side of the display 18 is mounted with a window 32. The protrusions 16a and 16b are brought into contact with the inner surface of the upper case 28 in a pressed state and assembled into the housing, and then assembled into the mobile phone device 21 which is a portable electronic device.

即ち、携帯電話装置２１は、表示器１８を保持したホルダ１０と、ホルダ１０が突条１６ａ，１６ｂを押圧状態にして内部に固定されると共に、表示器１８の表示面１８ａを外部から視認可能なウインドパネル３２を有する筐体とを備えており、ホルダ１０は、表示器１８の裏面１８ｂ側に位置する筐体構成部品である補強板金２６に固定されると共に、突条１６ａ，１６ｂをウインドパネル３２が装着される上ケース２８の内面に押圧状態に接触させて組み込まれる。 That is, the mobile phone device 21 is fixed to the holder 10 holding the display 18 and the holder 10 with the ridges 16a and 16b pressed, and the display surface 18a of the display 18 can be visually recognized from the outside. The holder 10 is fixed to a reinforcing sheet metal 26 which is a casing component located on the back surface 18b side of the display 18, and the ridges 16a and 16b are winded. The panel 32 is mounted on the inner surface of the upper case 28 in contact with the pressed state.

上述したように、サブ表示器１８を、従来の表示器の筐体側に貼り付けたスポンジ等のシートを用いることなく、ゴム等の弾性部材からなるホルダ１０のみで装着することができるため、防塵効果を兼ね備えた表示器装着構造を得ることができる。つまり、従来の表示器を保持する構造のように、表示器を保持するプラスチックホルダに加え、表示器のガラス面を保護するための別部材（例えば、弾性部材からなるシート）が必要になることがない。 As described above, since the sub-display 18 can be mounted only by the holder 10 made of an elastic member such as rubber without using a sheet of sponge or the like attached to the housing side of the conventional display, A display mounting structure having an effect can be obtained. In other words, in addition to the plastic holder that holds the display, a separate member for protecting the glass surface of the display (for example, a sheet made of an elastic member) is required, as in the conventional structure for holding the display. There is no.

ところで、従来の表示器を装着する構造において、防塵効果を更に高めるために、突条を設けた場合、突条の高さを高くすると、突条が接触する筐体の内圧が過度に高くなり筐体の厚さが厚くなってしまうのが避けられず、また、突条を二重に配置した場合、２つの突条の高さが同じにならずどちらかに荷重が偏ってしまうため、二重にした実質的効果を得ることが困難であった。 By the way, in the structure in which the conventional display is mounted, in order to further enhance the dustproof effect, when the protrusion is provided, if the height of the protrusion is increased, the internal pressure of the housing that the protrusion contacts becomes excessively high. It is inevitable that the thickness of the housing will be thick, and if the ridges are arranged in duplicate, the height of the two ridges will not be the same, and the load will be biased to either, It was difficult to obtain a doubled substantial effect.

二重構造にすると、防塵性は向上するが、部品の寸法バラツキや組み込みのバラツキを吸収するために、オーバラップ量を大きくすると圧力が高くなってしまう、という懸案が発生する。そこで、突出高さが低い外側の突条１６ｂと突出高さが高い内側の突条１６ａにした。突出高さが低い外側の突条１６ｂは下からの圧力がしっかりかかり密閉性が良く、突出高さが高い内側の突条１６ａは、圧力は低いがオーバラップ量は大きいので万が一の大きな寸法バラツキまたは振動や落下衝撃で内部部品が動いても追従できる。つまり、それぞれの効果で防塵性が更に向上する。 When the double structure is adopted, the dustproof property is improved, but there is a concern that the pressure increases when the overlap amount is increased in order to absorb the dimensional variation and the built-in variation. Therefore, the outer protrusion 16b with a low protrusion height and the inner protrusion 16a with a high protrusion height are used. The outer protrusion 16b with a low protrusion height is firmly sealed from the bottom, and the inner protrusion 16a with a high protrusion height is low in pressure but has a large overlap amount. Or it can follow even if the internal parts move due to vibration or drop impact. That is, the dust resistance is further improved by each effect.

また、ホルダ１０は、弾性部材からなる舌部１５による舌構造を有するので、サブ表示器１８をホルダ１０に簡単、且つ、容易に装着することができ、サブ表示器１８の組み込み工数を削減することができると共に、アンダーカット部を極力減らして生産性を向上させることができる。更に、サブ表示器１８は、表示面１８ａ側及び裏面１８ｂ側さらには側面を含む略全周がゴム等の弾性部材により覆われているので、落下等により、ガラス板からなる表示面１８ａを有するサブ表示器１８に衝撃が加わった場合でも、効果的に衝撃を吸収することができる。 Further, since the holder 10 has a tongue structure with the tongue portion 15 made of an elastic member, the sub-display 18 can be easily and easily mounted on the holder 10, and the number of steps for assembling the sub-display 18 is reduced. In addition, the undercut portion can be reduced as much as possible to improve productivity. Further, the sub-display 18 has a display surface 18a made of a glass plate due to dropping or the like because substantially the entire circumference including the display surface 18a side, the back surface 18b side, and the side surface is covered with an elastic member such as rubber. Even when an impact is applied to the sub-display 18, the impact can be effectively absorbed.

さらに、サブ表示器１８の略全周をホルダ１０で覆うことにより、自発光或いはバックライト等の照明光が、表示面用の開口以外から光漏れしてて、表示面の光量が落ちたりせず、表示面の光り方が均一になりやすくなる。また、逆に、メイン表示器などの照明光が侵入したりすることを防ぐこともできる。
なお、上記実施の形態において、ホルダ１０は、携帯電話装置のサブ表示器１８を保持する例を示しているが、これに限らず、さらに他の表示器を保持して、同様に装着しても良いし、ＰＤＡやポータブルゲーム機、ナビゲーション、電子辞書などの他の携帯電子機器において実施しても良いことは言うまでもない。 Further, by covering the substantially entire circumference of the sub-display 18 with the holder 10, illumination light such as self-light emission or backlight leaks from other than the opening for the display surface, and the amount of light on the display surface may decrease. In other words, the display surface shines easily. Conversely, it is possible to prevent the illumination light from entering the main display or the like.
In the above embodiment, the holder 10 shows an example of holding the sub-display 18 of the mobile phone device. However, the present invention is not limited to this. Needless to say, the present invention may be implemented in other portable electronic devices such as a PDA, portable game machine, navigation, and electronic dictionary.
