Description

本発明は、ディスプレイを備える電子機器に関する。 The present invention relates to an electronic device including a display.

ノート型ＰＣのような電子機器は、ディスプレイを搭載した第１筐体と、マザーボードを搭載した第２筐体とがヒンジで連結されている（例えば特許文献１参照）。 In an electronic device such as a notebook PC, a first housing on which a display is mounted and a second housing on which a motherboard is mounted are connected by a hinge (see, for example, Patent Document 1).

特許第６６９８１４４号公報Japanese Patent No. 6698144

ところで、上記特許文献１の構成は、ディスプレイの制御用の基板（ディスプレイ基板）を第１筐体のベゼル部材の内側に収納している。このため、ベゼル部材は、ディスプレイ基板の分だけ幅広になり、外観品質が低下する。 By the way, in the configuration of Patent Document 1, the substrate for controlling the display (display substrate) is housed inside the bezel member of the first housing. Therefore, the bezel member becomes wider by the amount of the display substrate, and the appearance quality deteriorates.

そこで、ディスプレイ基板を第２筐体内に収納し、ディスプレイとディスプレイ基板との間を第１筐体から第２筐体に亘るフレキシブル基板で接続することが考えられる。ところが、この構成では、ディスプレイ基板の分だけ第２筐体の薄型化や前後寸法が増大してしまう。特に、フレキシブル基板は、筐体間の回動動作に追従して柔軟に移動できる必要がある。このため、第２筐体内にはフレキシブル基板の移動スペースが必要となるため、ディスプレイ基板の配置スペースは最小限に抑えたい。 Therefore, it is conceivable to store the display board in the second housing and connect the display and the display board with a flexible board extending from the first housing to the second housing. However, in this configuration, the thickness of the second housing and the front-rear dimensions increase by the amount of the display board. In particular, the flexible substrate needs to be able to flexibly move following the rotational movement between the housings. For this reason, a space for moving the flexible substrate is required in the second housing, and the space for arranging the display substrate should be minimized.

The folded-back portion 36a on the side closer to the display 18 is folded back in a substantially semicircle from the forward direction to the downward and backward directions. The folded-back portion 36b on the side closer to the substrate 30 (31) is folded back at the exit of the folded-back portion 36a in a substantially semicircle from the rearward direction to the downward and forwardward directions.

第２筐体１４は、凹状部１４ｄを形成する前壁が波形板１４ｅで形成されている。波形板１４ｅは、下カバー材２１の内面から上カバー材２０の内面付近へと斜め上方に延在しつつ前方に延びた波形状の板部である。波形板１４ｅは、その上端と上カバー材２０の内面との間にフレキシブル基板３２（３３）が通過する隙間を形成している。波形板１４ｅは、Ｓ字形状部３６の形状に沿った断面形状を有し、フレキシブル基板３２（３３）の移動を阻害することなく、Ｓ字形状部３６の形状を保持することができる。 In the second housing 14, the front wall forming the concave portion 14d is formed of the corrugated plate 14e. The corrugated plate 14e is a corrugated plate portion extending diagonally upward from the inner surface of the lower cover material 21 to the vicinity of the inner surface of the upper cover material 20 and extending forward. The corrugated plate 14e forms a gap through which the flexible substrate 32 (33) passes between the upper end thereof and the inner surface of the upper cover material 20. The corrugated plate 14e has a cross-sectional shape that follows the shape of the S-shaped portion 36, and can maintain the shape of the S-shaped portion 36 without hindering the movement of the flexible substrate 32 (33).

フレキシブル基板３２（３３）は、折返し部３６ａでは円弧の外周側に位置し、折返し部３６ｂでは円弧の内周側に位置する表面３８に、基板３０（３１）に対する接続部３２ａ（３３ａ）を有する。つまり表面３８は、接続部３２ａ（３３ａ）が設けられた部分では上面である。接続部３２ａ（３３ａ）は、基板３０（３１）の下面に設けられた被接続部３０ａ（３１ａ）に接続されるコネクタ端子である。接続部３２ａ（３３ａ）は、表面３８から上向きに設置されている。図２及び図３中の参照符号３２ｂ（３３ｂ）は、フレキシブル基板３２（３３）に接続部３２ａ（３３ａ）を固定するための支持板である。 The flexible substrate 32 (33) has a connection portion 32a (33a) to the substrate 30 (31) on the surface 38 located on the outer peripheral side of the arc in the folded portion 36a and located on the inner peripheral side of the arc in the folded portion 36b. .. That is, the surface 38 is the upper surface at the portion where the connecting portion 32a (33a) is provided. The connecting portion 32a (33a) is a connector terminal connected to the connected portion 30a (31a) provided on the lower surface of the substrate 30 (31). The connecting portion 32a (33a) is installed facing upward from the surface 38. Reference numeral 32b (33b) in FIGS. 2 and 3 is a support plate for fixing the connection portion 32a (33a) to the flexible substrate 32 (33).

図２〜図４Ｃに示すように、第２筐体１４内には、ホルダ部材４０が設けられている。ホルダ部材４０は、アルミニウム等で形成された金属棒体であり、矩形の断面形状を有する。ホルダ部材４０は、ある程度の剛性が確保できれば樹脂製でもよい。ホルダ部材４０は、上カバー材２０の内面側にねじ４０ａで固定され、第２筐体１４と固定されている。ホルダ部材４０は、フレキシブル基板３２（３３）の折返し部３６ｂの内側に内包される位置に設けられている。ホルダ部材４０は、例えば２枚１組のフレキシブル基板３２に対して１本が横切るように設置され、２枚１組のフレキシブル基板３３に対して１本が横切るように設置されている（図２参照）。 As shown in FIGS. 2 to 4C, a holder member 40 is provided in the second housing 14. The holder member 40 is a metal rod body made of aluminum or the like, and has a rectangular cross-sectional shape. The holder member 40 may be made of resin as long as a certain degree of rigidity can be secured. The holder member 40 is fixed to the inner surface side of the upper cover material 20 with screws 40a, and is fixed to the second housing 14. The holder member 40 is provided at a position where it is included inside the folded-back portion 36b of the flexible substrate 32 (33). For example, one holder member 40 is installed so as to cross a pair of two flexible substrates 32, and one holder member 40 is installed so as to cross one set of two flexible substrates 33 (FIG. 2). reference).

ホルダ部材４０は、その下面４０ｂが両面テープ等の粘着剤４２を用いてフレキシブル基板３２（３３）の表面３８と固定されている。フレキシブル基板３２（３３）は、内部に金属線が配線されているため、弾性変形されたＳ字形状部３６では、常に各折返し部３６ａ，３６ｂが開いてしまう方向の反発力を発生している。つまりフレキシブル基板３２（３３）は、折返し部３６ｂから接続部３２ａ（３３ａ）までの前後方向に沿った部分が折返し部３６ｂを中心として、図４Ａ〜図４Ｃ中で下側に首振りする方向の反発力を生じている。ホルダ部材４０は、この部分と固定されることで、この首振り力を押さえ、接続部３２ａ（３３ａ）が被接続部３０ａ（３１ａ）から脱落することを防止している。 The lower surface 40b of the holder member 40 is fixed to the surface 38 of the flexible substrate 32 (33) by using an adhesive 42 such as double-sided tape. Since a metal wire is wired inside the flexible substrate 32 (33), the elastically deformed S-shaped portion 36 always generates a repulsive force in the direction in which the folded portions 36a and 36b are opened. .. That is, in the flexible substrate 32 (33), the portion along the front-rear direction from the folded-back portion 36b to the connecting portion 32a (33a) is in the direction of swinging downward in FIGS. 4A to 4C with the folded-back portion 36b as the center. Repulsive force is generated. By fixing the holder member 40 to this portion, the swinging force is suppressed and the connecting portion 32a (33a) is prevented from falling off from the connected portion 30a (31a).

次に、本実施形態の電子機器１０での筐体１２，１４間の回動動作と作用効果を説明する。 Next, the rotation operation and the action effect between the housings 12 and 14 in the electronic device 10 of the present embodiment will be described.

図４Ａに示す０度姿勢では、電子機器１０は、第２筐体１４の上面１４ａに第１筐体１２の正面１２ａが対向した状態で互いに積層された収納形態となっている。この状態では、フレキシブル基板３２（３３）は、下向きに配置されたヒンジ取付部３４の開口溝３４ａによって後方に引き寄せられ、Ｓ字形状部３６が波形板１４ｅに沿って配置されている。図４Ａ〜図４Ｃ中の参照符号Ｃは、ヒンジ１６による筐体１２，１４間の回動中心を示している。また、図４Ａ〜図４Ｃ中の参照符号４３は、第２筐体１４の下面１４ｂに取り付けられたゴム脚である。 In the 0-degree posture shown in FIG. 4A, the electronic devices 10 are stacked in a state in which the front surface 12a of the first housing 12 faces the upper surface 14a of the second housing 14. In this state, the flexible substrate 32 (33) is pulled backward by the opening groove 34a of the hinge mounting portion 34 arranged downward, and the S-shaped portion 36 is arranged along the corrugated plate 14e. Reference numeral C in FIGS. 4A to 4C indicates a center of rotation between the housings 12 and 14 by the hinge 16. Reference numeral 43 in FIGS. 4A to 4C is a rubber leg attached to the lower surface 14b of the second housing 14.

電子機器１０を使用する際には、第１筐体１２を開いて例えば９０度〜１３０度の間の角度姿勢に設定する。図４Ａに示す０度姿勢から第１筐体１２が開かれると、例えば図４Ｂに示す６５度姿勢までの間は、ヒンジ取付部３４の開口溝３４ａの出口の前後位置が次第に前方に移動し、フレキシブル基板３２（３３）が前方に押し込まれる。このため、フレキシブル基板３２（３３）は、第２筐体１４内でＳ字形状部３６が変形しつつ、折返し部３６ａが前方に移動する（図４Ｂ参照）。これによりフレキシブル基板３２（３３）は、筐体１２，１４間の回動動作時にディスプレイ１８と基板３０（３１）との相対距離が変化した場合であっても、この変化に柔軟に追従でき、断線等の不具合を生じることが抑制される。 When using the electronic device 10, the first housing 12 is opened and set to an angular posture of, for example, between 90 degrees and 130 degrees. When the first housing 12 is opened from the 0-degree posture shown in FIG. 4A, the front-rear position of the outlet of the opening groove 34a of the hinge mounting portion 34 gradually moves forward from the 0-degree posture shown in FIG. 4B to the 65-degree posture shown in FIG. 4B, for example. , The flexible substrate 32 (33) is pushed forward. Therefore, in the flexible substrate 32 (33), the folded-back portion 36a moves forward while the S-shaped portion 36 is deformed in the second housing 14 (see FIG. 4B). As a result, the flexible substrate 32 (33) can flexibly follow the change even when the relative distance between the display 18 and the substrate 30 (31) changes during the rotation operation between the housings 12 and 14. It is possible to prevent problems such as disconnection from occurring.

図４Ｂに示す６５度姿勢から図４Ｃに示す１３０度姿勢までの間は、ヒンジ取付部３４の開口溝３４ａの出口の前後位置がほとんど変化せず、フレキシブル基板３２（３３）の形状もほとんど変化しない。このため、この間の角度変化時にもフレキシブル基板３２（３３）が不具合を生じることが抑制されている。なお、図４Ｃに示す１３０度姿勢から図４Ａに示す０度姿勢までの回動時の動作は、上記した開き動作と逆に動作するだけであるため、説明は省略する。 From the 65-degree posture shown in FIG. 4B to the 130-degree posture shown in FIG. 4C, the front-rear position of the outlet of the opening groove 34a of the hinge mounting portion 34 hardly changes, and the shape of the flexible substrate 32 (33) also hardly changes. do not. Therefore, it is suppressed that the flexible substrate 32 (33) causes a defect even when the angle changes during this period. The operation during rotation from the 130-degree posture shown in FIG. 4C to the 0-degree posture shown in FIG. 4A is merely the reverse of the above-mentioned opening operation, and thus the description thereof will be omitted.

以上のように、本実施形態の電子機器１０は、第１筐体１２に設けられたディスプレイ１８と、第２筐体１４に設けられたプリント基板である基板３０（３１）と、ディスプレイ１８と基板３０（３１）とを接続するフレキシブル基板３２（３３）と、を備える。第２筐体１４内において、フレキシブル基板３２（３３）は、ディスプレイ１８から基板３０（３１）に向かう延在方向で順に並んで設けられ、互いに逆向きに湾曲した第１及び第２の折返し部３６ａ，３６ｂを有する。そして、フレキシブル基板３２（３３）は、折返し部３６ａでは外周側に位置し、折返し部３６ｂでは内周側に位置する表面３８に、基板３０（３１）に対する接続部３２ａ（３３ａ）を有する。 As described above, the electronic device 10 of the present embodiment includes the display 18 provided in the first housing 12, the substrate 30 (31) which is a printed circuit board provided in the second housing 14, and the display 18. A flexible substrate 32 (33) for connecting to the substrate 30 (31) is provided. In the second housing 14, the flexible substrates 32 (33) are provided side by side in the extending direction from the display 18 to the substrate 30 (31), and the first and second folded portions curved in opposite directions. It has 36a and 36b. The flexible substrate 32 (33) has a connection portion 32a (33a) to the substrate 30 (31) on the surface 38 located on the outer peripheral side of the folded portion 36a and on the inner peripheral side of the folded portion 36b.

このように当該電子機器１０は、ディスプレイ１８と接続される基板３０（３１）をディスプレイ１８側の第１筐体１２ではなく、第２筐体１４に搭載している。このため、第１筐体１２は、可及的に小型薄型化でき、ベゼル部材２９を幅狭に構成できる。この際、電子機器１０は、２つの筐体１２，１４間に亘るフレキシブル基板３２（３３）が基板３０（３１）側の第２筐体１４内で２つの折返し部３６ａ，３６ｂによってＳ字形状部３６を形成している。これによりフレキシブル基板３２（３３）は、筐体１２，１４間の回動動作時のディスプレイ１８と基板３０（３１）との間の相対距離の変化に柔軟に追従できる。 In this way, the electronic device 10 mounts the substrate 30 (31) connected to the display 18 not in the first housing 12 on the display 18 side but in the second housing 14. Therefore, the first housing 12 can be made as small and thin as possible, and the bezel member 29 can be configured to be narrow. At this time, in the electronic device 10, the flexible substrate 32 (33) extending between the two housings 12 and 14 has an S shape due to the two folded portions 36a and 36b in the second housing 14 on the substrate 30 (31) side. The portion 36 is formed. As a result, the flexible substrate 32 (33) can flexibly follow the change in the relative distance between the display 18 and the substrate 30 (31) during the rotational operation between the housings 12 and 14.

さらに基板３０（３１）は、２つの折返し部３６ａ，３６ｂのうち、基板３０（３１）に近い側の折返し部３６ｂの内周側に位置する表面３８に接続部３２ａ（３３ａ）を有する。このため、基板３０（３１）は、第２筐体１４の厚み方向（上下方向）でＳ字形状部３６の内周側となる位置、つまりフレキシブル基板３２（３３）に形成されたＳ字形状部３６の高さ寸法の範囲に少なくとも一部を収めることができる。その結果、基板３０（３１）が、フレキシブル基板３２（３３）の高さ寸法を大きく越えて上下方向に突出し、第２筐体１４の薄型化を阻害することが抑制される。しかも基板３０（３１）は、これと近い側の折返し部３６ｂの円弧の内周を向いて配置されるため、基板３０（３１）は、第２筐体１４内での前後方向位置をＳ字形状部３６（折返し部３６ｂ）に可及的に近づけて配置することができる。これにより第２筐体１４の前後方向寸法が基板３０（３１）によって増大することも抑制できる。従って、電子機器１０は、各筐体１２，１４の小型薄型化が可能となり、外観品質が向上する。 Further, the substrate 30 (31) has a connecting portion 32a (33a) on the surface 38 located on the inner peripheral side of the folded portion 36b on the side closer to the substrate 30 (31) among the two folded portions 36a and 36b. Therefore, the substrate 30 (31) has an S-shape formed on the flexible substrate 32 (33) at a position on the inner peripheral side of the S-shaped portion 36 in the thickness direction (vertical direction) of the second housing 14. At least a part can be contained within the height dimension range of the portion 36. As a result, it is possible to prevent the substrate 30 (31) from protruding in the vertical direction greatly exceeding the height dimension of the flexible substrate 32 (33) and hindering the thinning of the second housing 14. Moreover, since the substrate 30 (31) is arranged so as to face the inner circumference of the arc of the folded-back portion 36b on the side close to the substrate 30 (31), the substrate 30 (31) has an S-shaped position in the front-rear direction in the second housing 14. It can be arranged as close as possible to the shape portion 36 (folded portion 36b). As a result, it is possible to prevent the dimension in the front-rear direction of the second housing 14 from being increased by the substrate 30 (31). Therefore, in the electronic device 10, each of the housings 12 and 14 can be made smaller and thinner, and the appearance quality is improved.

当該電子機器１０は、第２筐体１４に相対的に固定され、折返し部３６ｂと接続部３２ａ（３３ａ）との間でフレキシブル基板３２（３３）を保持するホルダ部材４０を備える。これによりフレキシブル基板３２（３３）の折返し部３６ａ，３６ｂによって生じる反発力をホルダ部材４０で抑えることができ、フレキシブル基板３２（３３）の位置ずれや接続部３２ａ（３３ａ）の被接続部３０ａ（３１ａ）からの脱落を抑制できる。また、ホルダ部材４０は、筐体１２，１４間の回動時のフレキシブル基板３２（３３）の移動もサポートするため、接続部３２ａ（３３ａ）の脱落を一層抑制できる。 The electronic device 10 includes a holder member 40 that is relatively fixed to the second housing 14 and holds the flexible substrate 32 (33) between the folded-back portion 36b and the connecting portion 32a (33a). As a result, the repulsive force generated by the folded portions 36a and 36b of the flexible substrate 32 (33) can be suppressed by the holder member 40, and the misalignment of the flexible substrate 32 (33) and the connected portion 30a of the connecting portion 32a (33a) ( It is possible to suppress the dropout from 31a). Further, since the holder member 40 also supports the movement of the flexible substrate 32 (33) when rotating between the housings 12 and 14, it is possible to further suppress the disconnection of the connecting portion 32a (33a).

なお、ホルダ部材４０は、接続部３２ａ（３３ａ）が設置される表面３８の裏面に設けられてもよいが、この場合はフレキシブル基板３２（３３）の下側にホルダ部材４０の高さ分のスペースが必要となり、第２筐体１４の薄型化の障壁となってしまう。そこで、本実施形態では、ホルダ部材４０を表面３８側に設置することで、ホルダ部材４０が折返し部３６ｂの内周側のデッドスペースに収容できる。その結果、ホルダ部材４０が、第２筐体１４の薄型化を阻害することが抑制されている。また、ホルダ部材４０は、折返し部３６ｂと接続部３２ａ（３３ａ）との間に設けられることで、フレキシブル基板３２（３３）の伸縮性を阻害することもない。ホルダ部材４０の形状やフレキシブル基板３２（３３）の保持構造は変更してもよい。ホルダ部材４０は、省略してもよい。 The holder member 40 may be provided on the back surface of the front surface 38 on which the connecting portion 32a (33a) is installed. In this case, the holder member 40 is provided on the lower side of the flexible substrate 32 (33) by the height of the holder member 40. Space is required, which becomes a barrier to thinning the second housing 14. Therefore, in the present embodiment, by installing the holder member 40 on the surface 38 side, the holder member 40 can be accommodated in the dead space on the inner peripheral side of the folded-back portion 36b. As a result, it is suppressed that the holder member 40 hinders the thinning of the second housing 14. Further, since the holder member 40 is provided between the folded-back portion 36b and the connecting portion 32a (33a), the elasticity of the flexible substrate 32 (33) is not hindered. The shape of the holder member 40 and the holding structure of the flexible substrate 32 (33) may be changed. The holder member 40 may be omitted.

当該電子機器１０は、基板３０（３１）の被接続部３０ａ（３１ａ）が下向きに設けられ、フレキシブル基板３２（３３）の接続部３２ａ（３３ａ）が上向きに設けられている。これにより第２筐体１４では、マザーボード２６等と共に基板３０（３１）等も上カバー材２０側に固定される。このため、第２筐体１４は、下カバー材２１を取り外すことで容易に内部のメンテナンスが可能である。この際、第２筐体１４では、接続部３２ａ（３３ａ）が上向きであることで、下カバー材２１を取り外すだけで引っ張るだけで、接続部３２ａ（３３ａ）を被接続部３０ａ（３１ａ）から容易に取り外すことができる。従って、電子機器１０は、基板３０（３１）が第２筐体１４に搭載されているにもかかわらずディスプレイ１８の交換も容易である。 In the electronic device 10, the connected portion 30a (31a) of the substrate 30 (31) is provided downward, and the connecting portion 32a (33a) of the flexible substrate 32 (33) is provided upward. As a result, in the second housing 14, the substrate 30 (31) and the like are fixed to the upper cover material 20 side together with the motherboard 26 and the like. Therefore, the inside of the second housing 14 can be easily maintained by removing the lower cover material 21. At this time, in the second housing 14, since the connecting portion 32a (33a) faces upward, the connecting portion 32a (33a) can be pulled from the connected portion 30a (31a) simply by removing the lower cover material 21 and pulling it. It can be easily removed. Therefore, in the electronic device 10, the display 18 can be easily replaced even though the substrate 30 (31) is mounted on the second housing 14.

図５は、第２の実施形態の電子機器１０Ａを上から見下ろした模式的な平面図である。第２の実施形態に係る電子機器１０Ａにおいて、上記第１の実施形態に係る電子機器１０と同一又は同様な機能及び効果を奏する要素には同一の参照符号を付し、詳細な説明を省略する。 FIG. 5 is a schematic plan view of the electronic device 10A of the second embodiment looking down from above. In the electronic device 10A according to the second embodiment, elements having the same or similar functions and effects as the electronic device 10 according to the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. ..

The first display 44 has the same configuration as the display 18 of the first embodiment, and includes a display unit 18a and a touch panel unit 18b that face the front surface 12a and display an image. The second display 45 is configured in the same manner as the display unit 18a and the touch panel unit 45b, and includes a display unit 45a and a touch panel unit 45b that face the back surface 12b and display an image. As described above, the electronic device 10A has a dual display structure in which the displays 44 and 45 are provided on both sides of the front surface 12a and the back surface 12b of the first housing 12.

FIG. 7 is a schematic cross-sectional perspective view of the second housing 14 along the line VII-VII in FIG. FIG. 8 is a schematic side sectional view of the rear portion of the electronic device 10A in a state where the angular posture between the housings 12 and 14 is set to 65 degrees. In FIG. 7, the electronic device 10A is shown upside down, and the touch panel portion 18b and the like of the first housing 12 are not shown.

図６〜図８に示すように、電子機器１０Ａは、第１ディスプレイ４４の制御用のプリント基板（ＰＣＢ）としてディスプレイ基板３０及びタッチパネル基板３１を有し、第２ディスプレイ４５の制御用のプリント基板（ＰＣＢ）としてディスプレイ基板４６及びタッチパネル基板４７を有する。これら基板３０，３１，４６，４７は、全て第２筐体１４内に収容されている。 As shown in FIGS. 6 to 8, the electronic device 10A has a display board 30 and a touch panel board 31 as a printed circuit board (PCB) for controlling the first display 44, and is a printed circuit board for controlling the second display 45. It has a display board 46 and a touch panel board 47 as (PCB). All of these substrates 30, 31, 46, and 47 are housed in the second housing 14.

ディスプレイ基板４６は、第１ディスプレイ４４のディスプレイ基板３０と左右に並んで配置されている。ディスプレイ基板４６は、第２ディスプレイ４５のディスプレイ部４５ａでの映像表示を制御するためのサブボードである。ディスプレイ基板４６は、第１ディスプレイ４４のディスプレイ部１８ａと同様、筐体１２，１４間に亘るフレキシブル基板３２を介してディスプレイ部４５ａと電気的に接続されている。ディスプレイ部４５ａから延びたフレキシブル基板３２についても、第２筐体１４内でＳ字形状部３６が形成された後、その表面３８に設けられた接続部３２ａがディスプレイ基板４６の被接続部３０ａと接続される。 The display board 46 is arranged side by side with the display board 30 of the first display 44. The display board 46 is a sub-board for controlling the image display on the display unit 45a of the second display 45. Similar to the display unit 18a of the first display 44, the display board 46 is electrically connected to the display unit 45a via the flexible substrate 32 extending between the housings 12 and 14. Regarding the flexible substrate 32 extending from the display portion 45a, after the S-shaped portion 36 is formed in the second housing 14, the connecting portion 32a provided on the surface 38 thereof and the connected portion 30a of the display substrate 46 Be connected.

タッチパネル基板４７は、第１ディスプレイ４４のタッチパネル基板３１と前後方向に並んで配置されている。タッチパネル基板４７は、第２ディスプレイ４５のタッチパネル部４５ｂの制御用のサブボードである。タッチパネル基板４７は、タッチパネル部４５ｂで検出されたタッチ操作に基づくアナログ信号を所定のデジタル信号に変換してマザーボード２６に送信する。タッチパネル基板４７は、筐体１２，１４間に亘るフレキシブル基板４８を介してタッチパネル部４５ｂと電気的に接続されている。フレキシブル基板４８は、フレキシブル基板３３と同様、例えば左右の２枚１組で用いられている。 The touch panel substrate 47 is arranged side by side with the touch panel substrate 31 of the first display 44 in the front-rear direction. The touch panel board 47 is a sub-board for controlling the touch panel unit 45b of the second display 45. The touch panel board 47 converts an analog signal based on the touch operation detected by the touch panel unit 45b into a predetermined digital signal and transmits the analog signal to the motherboard 26. The touch panel substrate 47 is electrically connected to the touch panel portion 45b via a flexible substrate 48 extending between the housings 12 and 14. Like the flexible substrate 33, the flexible substrate 48 is used as a set of two left and right, for example.

基板４６，４７についても、他の基板３０，３１と同様、第２筐体１４の後部で上カバー材２０の内面に対して所定のブラケット等を介して固定され、下カバー材２１の内面に近い位置で水平に設置されている（図８参照）。フレキシブル基板４８は、フレキシブル基板３３と同様、絶縁性フィルムを材料に使った薄く且つ柔軟なプリント基板（ＦＰＣ）である。 Similar to the other substrates 30 and 31, the substrates 46 and 47 are also fixed to the inner surface of the upper cover material 20 at the rear portion of the second housing 14 via a predetermined bracket or the like, and are fixed to the inner surface of the lower cover material 21. It is installed horizontally at a close position (see FIG. 8). Like the flexible substrate 33, the flexible substrate 48 is a thin and flexible printed circuit board (FPC) using an insulating film as a material.

The flexible substrate 48 has an extending portion 48a extending forward beyond the touch panel substrate 31 to which the flexible substrate 33 is connected on the tip end side thereof. In the flexible substrate 48, the upward connecting portion 48b provided on the surface 50 of the extending portion 48a is connected to the downward connected portion 47a provided on the lower surface of the touch panel substrate 47. Reference numeral 48c in FIGS. 6 and 7 is a support plate for fixing the connection portion 48b to the flexible substrate 48. Although not shown, the flexible substrate 33 is also provided with the support plate 33b.

Also in the laminated flexible substrates 33 and 48, the holder member 40 may be provided at a position included inside the folded-back portion 36b (see FIGS. 7 and 8). The lower surface 40b of the holder member 40 is fixed to the surface 38 of the upper flexible substrate 33 by using an adhesive 42. The lower flexible substrate 48 is fixed to the upper flexible substrate 33. That is, the lower flexible substrate 48 is held by the holder member 40 via the upper flexible substrate 33.

Also in this case, the flexible substrate 32 connected to the display unit 18a of the first display 44 and the flexible substrate 32 connected to the display unit 45a of the second display 45 are laminated. In this configuration, the flexible substrate 32 connected to the display unit 18a is connected to the display substrate 30 on the proximal side from the folded-back portion 36b. In the flexible substrate 32 connected to the display portion 45a, the extending portion 48a protruding forward beyond the display substrate 30 is connected to the display substrate 46 on the distal side from the folded portion 36b. It should be noted that only the display boards 30 and 46 may be arranged side by side, and the touch panel boards 31 and 47 may be arranged side by side.

当該電子機器１０Ａでは、２枚のディスプレイ４４，４５を備える。このため、電子機器１０Ａは、第２筐体１４内に各ディスプレイ４４，４５に対するディスプレイ基板３０，４６及びタッチパネル基板３１，４７を備える。このため、電子機器１０Ａでは、例えばタッチパネル基板３１，４７を前後並びで配置し、筐体１２，１４の左右方向寸法の増大している。また、前後に並んだタッチパネル基板３１，４７に接続されるフレキシブル基板３３，４８は、それぞれの同一方向（上方）を向いた表面３８，５０に接続部３３ａ，４８ｂを設けている。これにより電子機器１０Ａでは、タッチパネル基板３１，４７の影響で第２筐体１４の薄型化が阻害されない。また電子機器１０Ａでは、タッチパネル基板３１，４７を前後に密接して並べることができ、第２筐体１４の前後寸法に対する影響も最小限となっている。 The electronic device 10A includes two displays 44 and 45. Therefore, the electronic device 10A includes the display boards 30, 46 and the touch panel boards 31, 47 for the displays 44, 45 in the second housing 14. Therefore, in the electronic device 10A, for example, the touch panel boards 31 and 47 are arranged side by side, and the dimensions of the housings 12 and 14 in the left-right direction are increased. Further, the flexible substrates 33 and 48 connected to the touch panel substrates 31 and 47 arranged in the front-rear direction are provided with connecting portions 33a and 48b on the surfaces 38 and 50 facing the same direction (upward), respectively.
