The first fixing portion 55 is fixed to the end portion of the first shaft 61. The first shaft 61 is inserted into the hole 57 a of the third fixing portion 57 and is rotatably supported by the third fixing portion 57. The first shaft 61 has an enlarged diameter portion 65 facing the third fixing portion 57 from the side.

第１の歯車６２は、第３の固定部５７と第１の軸６１の拡径部６５との間に配置されるとともに、第１の軸６１に固定されている。第１の歯車６２は、第１の軸６１と同軸上に位置される。ワッシャー６３及び皿ばね６４は、第１の軸６１に取り付けられ、協働して、第１のヒンジ５２にトルク（ブレーキトルク）を与える第１のブレーキ部６６を構成している。 The first gear 62 is disposed between the third fixed portion 57 and the enlarged diameter portion 65 of the first shaft 61 and is fixed to the first shaft 61. The first gear 62 is positioned coaxially with the first shaft 61. The washer 63 and the disc spring 64 are attached to the first shaft 61 and cooperate to constitute a first brake portion 66 that applies torque (brake torque) to the first hinge 52.

第１のブレーキ部６６は、第１の軸６１の拡径部６５とは反対側から第３の固定部５７に当接し、第３の固定部５７を第１の歯車６２に向けて押圧している。これにより、第３の固定部５７と第１の軸６１との間に所定のトルクが与えられている。 The first brake portion 66 abuts on the third fixing portion 57 from the side opposite to the diameter-enlarged portion 65 of the first shaft 61 and presses the third fixing portion 57 toward the first gear 62. ing. Thereby, a predetermined torque is applied between the third fixing portion 57 and the first shaft 61.

同様に、第２のヒンジ５３は、第２の軸７１（第２のヒンジ軸）と、第２の歯車７２と、ワッシャー７３と、皿ばね７４とを有する。第２の固定部５６は、第２の軸７１の端部に固定されている。第２の軸７１は、第３の固定部５７の孔５７ｂに挿入され、第３の固定部５７に回動可能に支持されている。第２の軸７１は、第３の固定部５７に側方から向かい合う拡径部７５を有する。 Similarly, the second hinge 53 includes a second shaft 71 (second hinge shaft), a second gear 72, a washer 73, and a disc spring 74. The second fixing portion 56 is fixed to the end portion of the second shaft 71. The second shaft 71 is inserted into the hole 57 b of the third fixing portion 57 and is rotatably supported by the third fixing portion 57. The second shaft 71 has an enlarged diameter portion 75 facing the third fixing portion 57 from the side.

第２の歯車７２は、第３の固定部５７と第２の軸７１の拡径部７５との間に配置されるとともに、第２の軸７１に固定されている。第２の歯車７２は、第２の軸７１と同軸上に位置される。ワッシャー７４及び皿ばね７４は、第２の軸７１に取り付けられ、協働して、第２のヒンジ５３にトルク（ブレーキトルク）を与える第２のブレーキ部７６を構成している。 The second gear 72 is disposed between the third fixed portion 57 and the enlarged diameter portion 75 of the second shaft 71 and is fixed to the second shaft 71. The second gear 72 is positioned coaxially with the second shaft 71. The washer 74 and the disc spring 74 are attached to the second shaft 71 and constitute a second brake portion 76 that applies torque (brake torque) to the second hinge 53 in cooperation.

第２のブレーキ部７６は、第２の軸７１の拡径部７５とは反対側から第３の固定部５７に当接し、第３の固定部５７を第２の歯車７２に向けて押圧している。これにより、第３の固定部５７と第２の軸７１との間に所定のトルクが与えられている。 The second brake portion 76 abuts on the third fixing portion 57 from the opposite side of the diameter-expanded portion 75 of the second shaft 71 and presses the third fixing portion 57 toward the second gear 72. ing. As a result, a predetermined torque is applied between the third fixed portion 57 and the second shaft 71.

第２の歯車７２は、第１の歯車６２に係合し、噛み合っている。つまり、第１及び第２の歯車６２，７２は、互いに連動して動く。第１及び第２の歯車６２，７２は、協働して連動部５４の一例を構成している。これにより、図９に示すように、第１のヒンジ５２と第２のヒンジ５３とは互いに連動しており、第１の固定部５５に対して第２の固定部５６を回動させると、第１の固定部５５に対して第３の固定部５７も回動する。すなわち、第１の筐体１１に対して第２の筐体２１を回動させると、第１の筐体１１に対して第３の筐体３１が自動的に回動される。 The second gear 72 is engaged with and meshed with the first gear 62. That is, the first and second gears 62 and 72 move in conjunction with each other. The first and second gears 62 and 72 constitute an example of the interlocking unit 54 in cooperation with each other. Thereby, as shown in FIG. 9, the first hinge 52 and the second hinge 53 are interlocked with each other, and when the second fixing portion 56 is rotated with respect to the first fixing portion 55, The third fixing portion 57 also rotates with respect to the first fixing portion 55. That is, when the second casing 21 is rotated with respect to the first casing 11, the third casing 31 is automatically rotated with respect to the first casing 11.

詳しく述べると、図２及び図３に示すように、第３の筐体３１は、ヒンジ部５，６によって、第１の筐体１１の第１の端部１１ａ及び第２の筐体２１の第１の端部２１ａに連結されている。第１の筐体１１と第２の筐体２１とが開かれた時、すなわち、第２の筐体２１が第１の筐体１１の操作面１２から離れる向きに回動された時、電子機器１は、操作面１２及び表示画面２２ａが外部に露出された使用状態になる。 More specifically, as shown in FIG. 2 and FIG. 3, the third casing 31 includes a first end portion 11 a of the first casing 11 and a second casing 21 by hinge portions 5 and 6. It is connected to the first end 21a. When the first casing 11 and the second casing 21 are opened, that is, when the second casing 21 is rotated away from the operation surface 12 of the first casing 11, the electronic The device 1 is in a use state in which the operation surface 12 and the display screen 22a are exposed to the outside.

このとき、第３の筐体３１は、第２の筐体２１の回動に連動し、操作面１２とは反対側に自動的に回動される。つまり、第２の筐体２１が操作面１２から離れる向きに回動された時、第３の筐体３１が操作面１２とは反対側に突出するように、第３の筐体３１が自動的に回動される。 At this time, the third casing 31 is automatically rotated to the opposite side to the operation surface 12 in conjunction with the rotation of the second casing 21. That is, when the second casing 21 is rotated in a direction away from the operation surface 12, the third casing 31 is automatically set so that the third casing 31 protrudes on the opposite side of the operation surface 12. Rotated.

換言すれば、電子機器１が使用状態にされる時、第３の筐体３１は、第１の筐体１１に対して真っ直ぐな姿勢から、第１のヒンジ５２の軸６１を回動中心にして、第１の筐体１１に対して折れ曲がる。これにより、第３の筐体３１は、第１の筐体１１の下壁１３の後端部の脚部１５よりも下方に突出する。 In other words, when the electronic device 1 is put into use, the third casing 31 is centered on the shaft 61 of the first hinge 52 from a straight posture with respect to the first casing 11. Then, it bends with respect to the first housing 11. As a result, the third housing 31 protrudes below the leg portion 15 at the rear end of the lower wall 13 of the first housing 11.

このように第３の筐体３１が操作面１２とは反対側に突出すると、この第３の筐体３１によって第１の筐体１１の第１の端部１１ａが第２の端部１１ｂに比べて持ち上がる。そして、第１の筐体１１の第２の端部１１ｂ及び第３の筐体３１が机上面Ｓに接し、第１の筐体１１は、当該第１の筐体１１の第２の端部１１ｂと、第３の筐体３１とによって支持される。このとき、第１の筐体１１の第１の端部１１ａは、机上面Ｓから浮いた状態になる。 When the third casing 31 projects in the opposite direction to the operation surface 12 in this way, the first end 11a of the first casing 11 becomes the second end 11b by the third casing 31. Compared with lifting. The second end 11 b and the third casing 31 of the first casing 11 are in contact with the desk surface S, and the first casing 11 is the second end of the first casing 11. 11b and the third casing 31. At this time, the first end portion 11a of the first housing 11 is in a state of floating from the desk surface S.

図３に示すように、電子機器１が使用状態にされた時、第１の筐体１１は、第１の端部１１ａから第２の端部１１ｂに向かう第１の方向Ｄ１に進むに従い低くなるように傾斜する。すなわち第１の筐体１１は、前下がりに傾斜する。第３の筐体３１は、第１の方向Ｄ１とは反対の第２の方向Ｄ２に進むに従い低くなるように傾斜する。すなわち第３の筐体３１は、後ろ下がり傾斜する。 As shown in FIG. 3, when the electronic device 1 is in a use state, the first housing 11 becomes lower as it proceeds in the first direction D1 from the first end portion 11a toward the second end portion 11b. Tilt to be. That is, the first housing 11 is inclined forward and downward. The third casing 31 is inclined so as to become lower as it proceeds in the second direction D2 opposite to the first direction D1. In other words, the third housing 31 is inclined backward and downward.

図３に示すように、電子機器１の使用状態では、第１の筐体１１の第２の端部１１ｂと、第３の筐体３１とが、ヒンジ部５，６の前後に分かれて位置される。第１の筐体１１は、当該第１の端部１１ａの第２の端部１１ｂと、第３の筐体３１とによって互いに異なる方向から支持される。 As shown in FIG. 3, when the electronic device 1 is in use, the second end portion 11 b of the first housing 11 and the third housing 31 are separated and positioned before and after the hinge portions 5 and 6. Is done. The first casing 11 is supported from different directions by the second end 11 b of the first end 11 a and the third casing 31.

図９に示すように、第１の歯車６２と第２の歯車７２のギア比は、例えば１対１である。すなわち第１及び第２の歯車６２，７２は、同一の直径の回転体の上に、同じサイズの歯がついている。このため、第１の固定部５５と第２の固定部５６との間の回動角度を２θとすると、第１の固定部５５と第３の固定部５７との間の回動角度はθとなる。すなわち、第１の筐体１１に対して第２の筐体２１を回動させたとき、第１の筐体１１と第２の筐体２１との間の回動角度の半分だけ、第１の筐体１１に対して第３の筐体３１は回動される。 As shown in FIG. 9, the gear ratio between the first gear 62 and the second gear 72 is, for example, 1: 1. That is, the first and second gears 62 and 72 have teeth of the same size on a rotating body having the same diameter. Therefore, if the rotation angle between the first fixing portion 55 and the second fixing portion 56 is 2θ, the rotation angle between the first fixing portion 55 and the third fixing portion 57 is θ. It becomes. That is, when the second casing 21 is rotated with respect to the first casing 11, only the half of the rotation angle between the first casing 11 and the second casing 21 is the first. The third casing 31 is rotated with respect to the casing 11.

換言すると、第２の筐体２１は、第１のヒンジ５２の回動量と第２のヒンジ５３の回動量とを合わせた大きさで回動され、第３の筐体３１は、第１のヒンジ５２の回動量で回動される。これにより、第３の筐体３１は、第１の筐体１１に対する第２の筐体２１の回動角度よりも小さな角度だけ第１の筐体１１に対して回動させる。なお「第１のヒンジの回動量」とは、第１の固定部５５に対する第３の固定部５７の回動量を指す。「第２のヒンジの回動量」とは第３の固定部５７に対する第２の固定部５６の回動量を指す。 In other words, the second casing 21 is rotated by a size that combines the rotation amount of the first hinge 52 and the rotation amount of the second hinge 53, and the third casing 31 is The hinge 52 is rotated by the rotation amount. Thereby, the third casing 31 is rotated with respect to the first casing 11 by an angle smaller than the rotation angle of the second casing 21 with respect to the first casing 11. The “rotation amount of the first hinge” refers to the rotation amount of the third fixing portion 57 relative to the first fixing portion 55. The “rotation amount of the second hinge” refers to the rotation amount of the second fixing portion 56 relative to the third fixing portion 57.

次に、電子機器１の作用について説明する。
図１に示すように、電子機器１が不使用状態の時、第２の筐体２１は、操作面１２を覆うように第１の筐体１１に重ねられている。このとき、電子機器１は、第１の筐体１１から第３の筐体３１まで真っ直ぐ伸びた状態であり、保管性及び可搬性に優れている。 Next, the operation of the electronic device 1 will be described.
As shown in FIG. 1, when the electronic device 1 is not in use, the second housing 21 is overlaid on the first housing 11 so as to cover the operation surface 12. At this time, the electronic device 1 is in a state of extending straight from the first housing 11 to the third housing 31, and is excellent in storage and portability.

図２及び図３に示すように、電子機器１を使用状態にする時、ユーザーは例えば第２の筐体２１の第２の端部２１ｂに手をかけ、操作面１２から離れる向きに第２の筐体２１を回動させる。これにより、操作面１２及び表示画面２２ａが外部に露出され、電子機器１が操作できるようにする。 As shown in FIGS. 2 and 3, when the electronic device 1 is put into a use state, for example, the user places a hand on the second end 21 b of the second casing 21 and moves the second end in a direction away from the operation surface 12. The case 21 is rotated. Thereby, the operation surface 12 and the display screen 22a are exposed to the outside so that the electronic device 1 can be operated.

このとき、第３の筐体３１は、第２の筐体２１の回動に伴って自動的に回動され、下方に向いて折れ曲がる。これにより、第１の筐体１１の第１の端部１１ａが持ち上げられ、第１の筐体１１は、後ろ上がりに傾斜した姿勢になる。このため、第１の筐体１１に設けられた入力部（例えばキーボード１６）も後ろ上がりに傾斜する。 At this time, the third casing 31 is automatically rotated along with the rotation of the second casing 21, and is bent downward. Thereby, the 1st edge part 11a of the 1st housing | casing 11 is lifted, and the 1st housing | casing 11 will be in the attitude | position which inclined to back-up. For this reason, the input part (for example, keyboard 16) provided in the 1st housing | casing 11 also inclines back up.

このような構成によれば、薄型化を図るとともに、使用時に傾斜することができる電子機器を提供される。 According to such a configuration, it is possible to provide an electronic device that can be thinned and can be tilted during use.

ノートＰＣのような電子機器は、携帯性向上のため薄型化が進められている。しかしながら、電子機器１が薄くなると、キーボードのような入力部と机上面との間に角度差が生じにくいため、キー入力時に手首に負担がかかることがある。 Electronic devices such as notebook PCs are being made thinner to improve portability. However, if the electronic device 1 is thin, an angle difference is unlikely to be generated between the input unit such as a keyboard and the desk surface, so that a burden may be applied to the wrist during key input.

ここで比較のため、ある電子機器を考える。電子機器を使用時に傾斜させるためには、筐体に収容されたスライド脚が外部にスライドして出てくる構造を採用することも考えられる。ここで、Ａ４サイズ（奥行き２１０ｍｍ）のノートＰＣで例えば５度のチルト角度を得るためには、電子機器の後端部を約１８ｍｍ持ち上げなくてはならない。筐体からスライド脚が１８ｍｍ飛び出して安定して電子機器を支持するためには、スライド脚は筐体の内部にも略同じ距離が入っていないと安定しにくい。 For comparison, consider an electronic device. In order to incline the electronic device during use, it may be possible to adopt a structure in which the slide legs accommodated in the housing slide out. Here, in order to obtain a tilt angle of, for example, 5 degrees with a notebook PC of A4 size (depth 210 mm), the rear end of the electronic device must be lifted by about 18 mm. In order for the slide leg to protrude 18 mm from the housing and stably support the electronic device, the slide leg is difficult to stabilize unless substantially the same distance is included inside the housing.

そのため、スライド脚の全長は、少なくとも３６ｍｍ必要となる。さらに電子機器は、筐体の肉厚やヒンジが固定される部分などが必要になる。このため、筐体の厚さは４０ｍｍを超えた厚いものになりやすい。例えば１０度のチルト角度を得るためには、筐体はさらに厚いものになる。 Therefore, the total length of the slide leg is required to be at least 36 mm. Furthermore, the electronic device requires a thickness of the housing and a portion to which the hinge is fixed. For this reason, the thickness of the housing tends to be thicker than 40 mm. For example, in order to obtain a tilt angle of 10 degrees, the casing becomes thicker.

さらに、スライド脚はぐらつきやすい。なぜなら、筐体からスライド脚をスライドさせるためには、スライド脚と、このスライド脚を収納する収納部との間にある程度のクリアランス（ガタ）が必要になる。このため、スライド脚は安定した保持が難しく、ノートＰＣが使用時にぐらつく可能性がある。 Furthermore, the slide legs are easily wobbled. This is because in order to slide the slide leg from the housing, a certain amount of clearance (backlash) is required between the slide leg and the storage portion for storing the slide leg. For this reason, it is difficult to hold the slide leg stably, and the notebook PC may be wobbled during use.

一方で、本実施形態では、電子機器１は、操作面１２を有した第１の筐体１１と、第２の筐体２１と、ヒンジ部５，６と、第１の筐体１１の端部に連結され、第２の筐体２１の回動に連動して操作面１２とは反対側に回動される可動部３１と、を備える。この構成では、第２の筐体２１を回動させた時、可動部３１が自動的に回動されて、第１の筐体１１の下方に突出する。これにより、第１の筐体１１が後ろ上がりに傾斜し、第１の筐体１１に設けられた操作面１２も後ろ上がりに傾斜する。これにより、例えばキー入力のような操作時に、ユーザーの手首に負担がかかりにくくなる。 On the other hand, in this embodiment, the electronic device 1 includes the first casing 11 having the operation surface 12, the second casing 21, the hinge portions 5 and 6, and the end of the first casing 11. And a movable part 31 that is connected to the part and rotated to the opposite side of the operation surface 12 in conjunction with the rotation of the second casing 21. In this configuration, when the second casing 21 is rotated, the movable portion 31 is automatically rotated and protrudes below the first casing 11. As a result, the first casing 11 tilts backward and the operation surface 12 provided on the first casing 11 also tilts backward and upward. This makes it difficult for the user's wrist to be burdened during an operation such as key input.

ここで、可動部３１は、例えば略水平な姿勢から回動されて、操作面１２とは反対側に突出する。このような構成であれば、上記スライド脚を有する構造に比べて、第１の筐体１１を薄くすることができる。さらに、回動による構造は、上記スライド脚のスライド構造に比べて必要なクリアランスが小さく、ガタツキにくい。このため、使用時に電子機器１が安定しやすい。 Here, the movable portion 31 is rotated from a substantially horizontal posture, for example, and protrudes to the side opposite to the operation surface 12. With such a configuration, the first housing 11 can be made thinner than the structure having the slide legs. Further, the pivoting structure requires less clearance than the sliding structure of the slide leg and is less likely to rattle. For this reason, the electronic device 1 is easy to stabilize at the time of use.

本実施形態では、電子機器１は、第１の筐体１１と第３の筐体３１とを回動可能に連結した第１のヒンジ５２と、第２の筐体２１と第３の筐体３１とを回動可能に連結した第２のヒンジ５３と、第１のヒンジ５２と第２のヒンジ５３とを連動させた連動部５４とを有する。これによれば、第２の筐体２１の回動に連動させて第３の筐体３１を回動させるヒンジ部５，６を、比較的コンパクトに構成することができる。これは、電子機器１の薄型化に寄与する。 In the present embodiment, the electronic device 1 includes a first hinge 52 in which the first casing 11 and the third casing 31 are rotatably connected, the second casing 21, and the third casing. The first hinge 52 and the second hinge 53 are interlocked with each other. The second hinge 53 is rotatably connected to the first hinge 52 and the second hinge 53 is interlocked with the second hinge 53. According to this, the hinge parts 5 and 6 which rotate the 3rd housing | casing 31 in response to rotation of the 2nd housing | casing 21 can be comprised comparatively compactly. This contributes to the thinning of the electronic device 1.

本実施形態では、電子機器１の使用状態では、第１の筐体１１は前下がりに傾斜し、第３の筐体３１は後ろ下がりに傾斜する。このため、第１の筐体１１は、第２の端部１１ｂと第３の筐体３１とによって互いに異なる複数の方向から支持される。このため、第１の筐体１１は安定して支持され、電子機器１をより安定して使用することができる。 In the present embodiment, when the electronic apparatus 1 is in use, the first casing 11 is inclined forward and the third casing 31 is inclined downward. For this reason, the first housing 11 is supported from a plurality of different directions by the second end portion 11 b and the third housing 31. For this reason, the 1st housing | casing 11 is supported stably and the electronic device 1 can be used more stably.

本実施形態では、第３の筐体３１には、電子部品（例えばコネクタ４３）が収容されている。すなわち、電子機器１を傾斜させるチルト部を利用して、電子部品が収容されている。これは、電子機器１の高密度実装及び薄型化に寄与する。 In the present embodiment, the third casing 31 accommodates an electronic component (for example, a connector 43). That is, an electronic component is accommodated using a tilt unit that tilts the electronic device 1. This contributes to high-density mounting and thinning of the electronic device 1.

本実施形態では、第３の筐体３１には、電子機器１のなかで比較的重い部品であるバッテリー４１が搭載されている。このため、第１の筐体１１の第１の端部１１ａを持ち上げた状態でも、電子機器１の重心が低い位置に維持されやすく、電子機器１がより安定しやすい。 In the present embodiment, a battery 41 that is a relatively heavy component in the electronic device 1 is mounted on the third casing 31. For this reason, even when the first end portion 11a of the first housing 11 is lifted, the electronic device 1 is easily maintained at a low center of gravity, and the electronic device 1 is more stable.

またバッテリー４１は、電子機器１のなかで比較的厚い部品のひとつである。バッテリー４１を第３の筐体３１に搭載すると、バッテリー４１と表示装置２２とが重ならないため、製品を薄く設計することができる。これにより、より可搬性に優れた電子機器１が提供可能になる。また、バッテリー４１を第３の筐体３１に搭載すると、バッテリー４１の厚さにとらわれず、第１及び第２の筐体１１，２１の薄型化を図ることができ、電子機器１の薄型化をより図ることができる。 The battery 41 is one of relatively thick parts in the electronic device 1. When the battery 41 is mounted on the third casing 31, the battery 41 and the display device 22 do not overlap with each other, so that the product can be designed to be thin. Thereby, it becomes possible to provide the electronic device 1 having more excellent portability. Further, when the battery 41 is mounted on the third housing 31, the first and second housings 11 and 21 can be thinned regardless of the thickness of the battery 41, and the electronic device 1 can be thinned. Can be further planned.

本実施形態では、第３の筐体３１は、電子機器１の不使用時では、第１の筐体１１及び第２の筐体２１とは重ならない位置に設けられるとともに、第１の筐体１１よりも厚い。そして、この比較的厚い第３の筐体３１を利用してコネクタ４３が搭載されている。このため、コネクタ４３の高さ（厚さ）にとらわれずに、第１の筐体１１の薄型化を図ることができ、電子機器１の薄型化をより図ることができる。 In the present embodiment, the third casing 31 is provided at a position that does not overlap the first casing 11 and the second casing 21 when the electronic apparatus 1 is not used, and the first casing Thicker than 11. The connector 43 is mounted using the relatively thick third casing 31. For this reason, the first casing 11 can be made thinner without being restricted by the height (thickness) of the connector 43, and the electronic device 1 can be made thinner.

本実施形態では、第３の筐体３１の厚さは、第１の筐体１１と第２の筐体２１とを合わせた厚さと略同じであり、第２の筐体２１が第１の筐体１１に重ねられた時、第３の筐体３１の表面と第２の筐体２１の表面とが略同じ平面上に位置される。これによれば、電子機器１の可搬性が向上するとともに、美観も向上する。 In the present embodiment, the thickness of the third casing 31 is substantially the same as the combined thickness of the first casing 11 and the second casing 21, and the second casing 21 is the first When overlaid on the casing 11, the surface of the third casing 31 and the surface of the second casing 21 are positioned on substantially the same plane. According to this, the portability of the electronic device 1 is improved, and the beauty is also improved.

本実施形態では、第３の筐体３１は、電子機器１の不使用時に、第１の筐体１１と略平行に並ぶ。すなわち電子機器１は、不使用状態でフラットな形状になる。これによれば、電子機器１が不使用状態でより薄いものになり、保管性や可搬性がより向上する。 In the present embodiment, the third housing 31 is arranged substantially in parallel with the first housing 11 when the electronic device 1 is not used. That is, the electronic device 1 has a flat shape when not in use. According to this, the electronic device 1 becomes thinner when not in use, and the storability and portability are further improved.

本実施形態では、第２の筐体２１は、第１のヒンジ５２の回動量と第２のヒンジ５３の回動量とを合わせた大きさで回動され、第３の筐体３１は、第１のヒンジ５２の回動量で回動されることで、第２の筐体２１よりも小さな角度だけ回動される。これによれば、第３の筐体３１をチルトに必要な角度だけ回動させることができる。 In the present embodiment, the second casing 21 is rotated by a size that combines the rotation amount of the first hinge 52 and the rotation amount of the second hinge 53, and the third casing 31 is By being rotated by the rotation amount of one hinge 52, it is rotated by an angle smaller than that of the second housing 21. According to this, the 3rd housing | casing 31 can be rotated only the angle required for a tilt.

本実施形態では、第３の筐体３１の後壁３３は、円弧状に形成されている。この後壁３３は、電子機器１の使用状態で、机上面Ｓに接する壁部である。この後壁３３が円弧状に形成されていると、第３の筐体３１の回動角度によらず、第３の筐体３１が机上面Ｓに安定して当接しやすい。このため、電子機器１の支持がより安定する。 In the present embodiment, the rear wall 33 of the third housing 31 is formed in an arc shape. The rear wall 33 is a wall portion that is in contact with the desk surface S when the electronic apparatus 1 is in use. When the rear wall 33 is formed in an arc shape, the third casing 31 is likely to stably contact the desk surface S regardless of the rotation angle of the third casing 31. For this reason, the support of the electronic device 1 becomes more stable.

以下、電子機器１のいつくかの変形例について説明する。なお以下に説明する以外の構成は、上記実施形態と同じである。 Hereinafter, some modified examples of the electronic apparatus 1 will be described. Configurations other than those described below are the same as in the above embodiment.

図１０は、電子機器１の第１の変形例を示す。図１０に示すように、第１の歯車６２と第２の歯車７２のギア比は、１対１に限定されない。本変形例では、第１の歯車６２と第２の歯車７２のギア比は、例えば２対３である。このため、第１の固定部５５と第３の固定部５７との間の回動角度がθの時、第３の固定部５７と第２の固定部５６との間の回動角度は３分の２θとなる。 FIG. 10 shows a first modification of the electronic device 1. As shown in FIG. 10, the gear ratio between the first gear 62 and the second gear 72 is not limited to 1: 1. In the present modification, the gear ratio between the first gear 62 and the second gear 72 is, for example, 2 to 3. Therefore, when the rotation angle between the first fixing portion 55 and the third fixing portion 57 is θ, the rotation angle between the third fixing portion 57 and the second fixing portion 56 is 3 2θ of a minute.

このため、同じ角度だけ第２の筐体２１を回動させた時、ギア比が１対１の場合に比べて、本変形例の方が第３の筐体３１がより大きく回動される。このため、第１の筐体１１をより大きく傾けることができる。すなわち、より大きなチルトをつけることができる電子機器１が提供される。 Therefore, when the second casing 21 is rotated by the same angle, the third casing 31 is rotated more greatly in the present modification than in the case where the gear ratio is 1: 1. . For this reason, the 1st housing | casing 11 can be inclined more largely. That is, the electronic device 1 that can provide a larger tilt is provided.

図１１は、電子機器１の第２の変形例を示す。図１１に示すように、本変形例では、第２のヒンジ５３のブレーキ部７６が省略されている。第２のヒンジ５３のブレーキ部７６を省略しても、第２のヒンジ５３は、第１及び第２の歯車６２，７２を介して第１のブレーキ部６６からトルクを受けることができる。皿ばねを含むブレーキ部は、比較的高価であるため、ブレーキ部７６を省略することができると、電子機器１のコストダウンに寄与する。なお、第２のヒンジ５３のブレーキ部７６を省略するのに代えて、第１のヒンジ５２のブレーキ部６６を省略してもよい。 FIG. 11 shows a second modification of the electronic device 1. As shown in FIG. 11, in this modification, the brake part 76 of the second hinge 53 is omitted. Even if the brake portion 76 of the second hinge 53 is omitted, the second hinge 53 can receive torque from the first brake portion 66 via the first and second gears 62 and 72. Since the brake part including the disc spring is relatively expensive, if the brake part 76 can be omitted, it contributes to the cost reduction of the electronic device 1. Instead of omitting the brake portion 76 of the second hinge 53, the brake portion 66 of the first hinge 52 may be omitted.

図１２は、電子機器１の第３の変形例を示す。図１２に示すように、本変形例では、上記実施形態に比べて、第２のヒンジ５３のブレーキ部７６の皿ばねが減らされ、トルクが小さくなっている。これによれば、電子機器１のコストダウンを図るとともに、例えば第２の変形例よりも第２のヒンジ５３のガタツキをより抑制することができる。 FIG. 12 shows a third modification of the electronic device 1. As shown in FIG. 12, in this modification, the disc spring of the brake portion 76 of the second hinge 53 is reduced and the torque is reduced as compared with the above embodiment. According to this, while aiming at the cost reduction of the electronic device 1, the backlash of the 2nd hinge 53 can be suppressed more than the 2nd modification, for example.

図１３及び図１４は、電子機器１の第４の変形例を示す。図１３に示すように、本変形例の連動部５４は、第１及び第２の歯車６２，７２に代えて、第１のヒンジ５２の動きと第２のヒンジ５３の動きとを連動させるリンク機構８１を有する。 13 and 14 show a fourth modification of the electronic device 1. As shown in FIG. 13, the interlocking portion 54 of this modification is a link that interlocks the movement of the first hinge 52 and the movement of the second hinge 53 instead of the first and second gears 62 and 72. A mechanism 81 is included.

リンク機構８１は、リンク片８２を有する。リンク片８２の第１の端部は、第１のヒンジ５２の第１の軸６１の例えば拡径部６５に回動可能に連結されている。リンク片８２の第２の端部は、第２のヒンジ５３の第２の軸７１の例えば拡径部７５に回動可能に連結されている。第１及び第２のヒンジ５２，５３は、リンク片８２を介して互いに連動する。 The link mechanism 81 has a link piece 82. The first end portion of the link piece 82 is rotatably connected to, for example, the enlarged diameter portion 65 of the first shaft 61 of the first hinge 52. The second end portion of the link piece 82 is rotatably connected to, for example, the enlarged diameter portion 75 of the second shaft 71 of the second hinge 53. The first and second hinges 52 and 53 are interlocked with each other via a link piece 82.

図１５は、電子機器１の第５の変形例を示す。図１４に示すように、本変形例では、第３の筐体３１にアンテナ８５が収容されている。アンテナ８５は、「電子部品」の一例である。第１及び第２の筐体１１，２１は、例えば金属製である。第３の筐体３１は、プラスチック製である。アンテナ８５は、第３の筐体３１の例えば上壁３４に沿って配置されている。電子機器１が使用状態にあるとき、アンテナ８５は、第１及び第２の筐体１１，２１とは異なる方向に向くとともに、第１及び第２の筐体１１，２１に覆われない。このような構成によれば、アンテナの送受信が、第１及び第２の筐体１１，２１や表示装置２２から影響を受けにくく、より良好になる。 FIG. 15 shows a fifth modification of the electronic device 1. As shown in FIG. 14, in the present modification, an antenna 85 is accommodated in the third housing 31. The antenna 85 is an example of an “electronic component”. The first and second housings 11 and 21 are made of metal, for example. The third housing 31 is made of plastic. The antenna 85 is disposed along the upper wall 34 of the third housing 31, for example. When the electronic apparatus 1 is in use, the antenna 85 faces in a direction different from that of the first and second casings 11 and 21 and is not covered by the first and second casings 11 and 21. According to such a configuration, the transmission / reception of the antenna is less affected by the first and second casings 11 and 21 and the display device 22, and becomes better.

図１６は、電子機器１の第６の変形例を示す。図１５に示すように、本変形例では、第１の筐体１１の第１の端部１１ａに、可動部９１が設けられている。可動部９１は、上記実施形態の第３の筐体３１と同様に、第２の筐体２１が操作面１２から離れる向きに回動された時、操作面１２とは反対側に突出するように可動部９１が回動される。図１５に示すように、可動部９１は、第１の筐体１１の一部に対応して設けられてもよい。なお図１に示すように、可動部３１が第１及び第２の筐体１１，２１と略同じ幅を有すると、可動部３１による電子機器１の支持がより安定する。 FIG. 16 shows a sixth modification of the electronic device 1. As shown in FIG. 15, in this modification, a movable portion 91 is provided at the first end portion 11 a of the first housing 11. Similar to the third casing 31 of the above-described embodiment, the movable portion 91 protrudes to the opposite side of the operation surface 12 when the second casing 21 is rotated away from the operation surface 12. The movable portion 91 is rotated. As shown in FIG. 15, the movable portion 91 may be provided corresponding to a part of the first housing 11. As shown in FIG. 1, when the movable portion 31 has substantially the same width as the first and second casings 11 and 21, the electronic device 1 is more stably supported by the movable portion 31.
