Description

本発明は、一対の筐体をヒンジ機構により互いに開閉可能に連結してなる折り畳み式電子機器に関するものである。   The present invention relates to a foldable electronic device in which a pair of housings are connected to each other by a hinge mechanism so as to be opened and closed.

折り畳み式電子機器として、互いに平行な２つのヒンジ軸を有する平行２軸ヒンジにより、一対の筐体を互いに開閉可能に連結した電子機器が提案されている(例えば特許文献１)。
例えば、図８に示すように、一対の筺体(100)(101)を互いに平行な２本のヒンジ軸(103)(104)を有する平行２軸ヒンジ(102)(102)により連結し、各筺体(100)(101)をヒンジ軸(103)(104)を中心として回転させることで、一方の筺体(100)に対して他方の筺体(101)を相対的に開閉可能としている。 As a foldable electronic device, an electronic device has been proposed in which a pair of housings are connected to each other so as to be openable and closable by a parallel biaxial hinge having two hinge shafts parallel to each other (for example, Patent Document 1).
For example, as shown in FIG. 8, a pair of housings (100) (101) are connected by parallel two-axis hinges (102) (102) having two hinge shafts (103) (104) parallel to each other. By rotating the casings (100) and (101) about the hinge shafts (103) and (104), the other casing (101) can be opened and closed relative to the one casing (100).

折り畳み式電子機器は、図８に示すように、第１筐体(100)及び第２筺体(101)に夫々タッチパネルアッセンブリ(120)を構成するスクリーン(121)を具え、第１筺体(100)を第２筺体(101)に対して相対的に開き方向となる開状態に移動させることで、スクリーン(121)が同一平面となるようにしている。   As shown in FIG. 8, the foldable electronic device includes a screen (121) that constitutes a touch panel assembly (120) in each of the first casing (100) and the second casing (101), and the first casing (100). Is moved to an open state that is in an opening direction relative to the second casing (101), so that the screen (121) is in the same plane.

各筺体(100)(101)を開状態としたときに、両スクリーン(121)(121)に跨って１つの画像を表示でき、表示される画像が連続性を維持できるように、各スクリーン(121)(121)は、開状態で対向する筐体(100)(101)の端面まで設けることが望まれている。   When each housing (100) (101) is opened, one image can be displayed across both screens (121) and (121), and each screen ( It is desired that 121) and 121) be provided up to the end surfaces of the opposite casings 100 and 101 in the open state.

一方、スクリーン(121)は厚みを有しており、また、電子機器自体に薄型化の要請があるから、スクリーン(121)の下方にヒンジ軸を通すことのない構造が望まれている。   On the other hand, since the screen (121) has a thickness and the electronic device itself is required to be thin, a structure that does not allow the hinge shaft to pass under the screen (121) is desired.

そこで、図８に示すように、平行２軸ヒンジ(102)(102)を筺体(100)(101)の両側に配置することが提案されているが、筐体(100)(101)には、平行２軸ヒンジ(102)(102)から突設されたヒンジ軸(103)(104)を筐体(100)(101)に取り付けるために、少なくとも平行２軸ヒンジ(102)以上の幅Ｗをスクリーン(121)(121)の左右に設ける必要がある。   Thus, as shown in FIG. 8, it has been proposed to arrange parallel biaxial hinges (102) and (102) on both sides of the casings (100) and (101). In order to attach the hinge shaft (103) (104) projecting from the parallel biaxial hinge (102) (102) to the housing (100) (101), at least a width W equal to or greater than the parallel biaxial hinge (102) Must be provided on the left and right of the screen (121) (121).

特開２０１０−２４９２０９号公報JP 2010-249209 A

平行２軸ヒンジ(102)(102)のヒンジ軸(103)(104)の筐体(100)(101)への侵入長さが短いと、筐体(100)(101)を開閉したときに、対向するヒンジ軸どうしの軸芯がズレて、筐体(100)(101)の捻り方向に力が作用し、ガタツキが生じることがある。   When the intrusion length of the hinge shaft (103) (104) of the parallel biaxial hinge (102) (102) into the housing (100) (101) is short, when the housing (100) (101) is opened and closed The shaft centers of the hinge shafts facing each other are displaced, and a force acts in the twisting direction of the housings (100) and (101), which may cause rattling.

また、平行２軸ヒンジ(102)(102)を夫々スクリーン(121)の左右に設けるために、筺体(100)(101)に幅広の領域Ｗを設けることは、電子機器のデザインに大きな制約を課すこととなる。さらには、筐体(100)(101)が拡幅して電子機器の大型化に繋がることがある。   In addition, in order to provide the parallel biaxial hinges (102) and (102) on the left and right sides of the screen (121), the provision of the wide area W in the casings (100) and (101) greatly restricts the design of the electronic device. Will be imposed. Furthermore, the casing (100) (101) may be widened, leading to an increase in size of the electronic device.

本発明の目的は、平行２軸ヒンジの幅を最小限に抑えながらも、筐体どうしの捻り方向のガタツキを抑えることのできる折り畳み式電子機器を提供することである。   An object of the present invention is to provide a foldable electronic device that can suppress backlash in a twisting direction between cases while minimizing the width of a parallel biaxial hinge.

A connecting rod connecting the two parallel biaxial hinges;

本発明に係る折り畳み式電子機器によれば、平行２軸ヒンジどうしを連結杆によって互いに回転できないように連結しているから、平行２軸ヒンジどうしは、夫々対向するヒンジ軸が捻れ方向にズレることはなく、互いに平行な状態を維持できる。このため、平行２軸ヒンジから突設されるヒンジ軸は、夫々その突出量を短くすることができ、筐体への侵入長さも可及的に短くできる。
従って、筐体は、スクリーン左右の幅を短くでき、筐体に対するスクリーンの割合を大きくすることができる。
これにより、デザイン上の制約も小さくできるから、電子機器のデザインバリエーションに自由度をもたせることができる。 According to the foldable electronic device according to the present invention, the parallel two-axis hinges are connected to each other by the connecting rod so that they cannot rotate with each other, and thus the parallel two-axis hinges are displaced in the twisting direction. No, they can maintain a parallel state. For this reason, each of the hinge shafts protruding from the parallel biaxial hinge can reduce the amount of protrusion, and the length of penetration into the housing can be reduced as much as possible.
Therefore, the housing can shorten the width of the left and right sides of the screen, and can increase the ratio of the screen to the housing.
As a result, design constraints can be reduced, and the design variations of electronic devices can be given a degree of freedom.

また、上記連結杆を例えば電子機器の閉状態における両筐体の厚さと略一致する板状に構成することで、連結杆は、本の背の如き外観とすることができ、折り畳み式電子機器のデザイン性を向上させることができる。   Further, by configuring the connecting rod in a plate shape that substantially matches the thickness of both housings in the closed state of the electronic device, for example, the connecting rod can have an appearance like the back of a book, and the folding electronic device The design can be improved.

以下、本発明の実施の形態につき、図面に沿って具体的に説明する。
本発明の一実施形態である折り畳み式電子機器(１)は、図１乃至図３に示す如く、第１筐体(10)と第２筐体(20)とを開閉可能に連結して構成され、図１に示す閉状態と図２及び図３に示す開状態との間で開閉が可能である。 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
A foldable electronic device (1) according to an embodiment of the present invention is configured by connecting a first housing (10) and a second housing (20) so as to be openable and closable as shown in FIGS. Thus, it can be opened and closed between the closed state shown in FIG. 1 and the open state shown in FIGS.

なお、以下の記載では、「開状態」とは、両筐体(10)(20)を相対的に開いて、両筐体(10)(20)に装着されるタッチパネルアセンブリ(60)(60)を構成するスクリーン(61)(61)を同一方向へ向けて略同一平面上で並べた状態(図２及び図３参照)、「閉状態」とは、両筐体(10)(20)を互いにスクリーン(61)(61)が接近する方向に閉じて、スクリーン(61)(61)どうしを対向させた状態である(図１参照)。   In the following description, the `` open state '' means the touch panel assemblies (60) (60) attached to both the casings (10) and (20) by relatively opening both the casings (10) and (20). The screens (61) and (61) constituting the) are arranged in substantially the same plane in the same direction (see FIGS. 2 and 3), and the “closed state” means both cases (10) and (20) Are closed in the direction in which the screens 61 and 61 approach each other, and the screens 61 and 61 are opposed to each other (see FIG. 1).

図１及び図６に示す如く、第１筐体(10)と第２筐体(20)は、ヒンジ機構(30)により連結して構成される。ヒンジ機構(30)は、筐体(10)(20)の一端側の左右に夫々配備された平行２軸ヒンジ(34)(35)を、連結杆(36)によって連結して構成することができる。
平行２軸ヒンジ(34)(35)と連結杆(36)は溶接、ネジ止め、接着等の要領で連結することができ、また、平行２軸ヒンジ(34)(35)と連結杆(36)を一体に形成することもできる。 As shown in FIG.1 and FIG.6, the 1st housing | casing (10) and the 2nd housing | casing (20) are connected and comprised by the hinge mechanism (30). The hinge mechanism (30) may be configured by connecting parallel biaxial hinges (34) and (35) respectively provided on the left and right sides of one end side of the housing (10) and (20) by a connecting rod (36). it can.
The parallel biaxial hinges (34) (35) and the connecting rod (36) can be connected by welding, screwing, bonding, etc., and the parallel biaxial hinges (34) (35) and the connecting rod (36) ) Can be formed integrally.

平行２軸ヒンジ(34)(35)及び連結杆(36)に強度を具備するために、平行２軸ヒンジ(34)(35)及び連結杆(36)は金属から構成することが望ましい。   In order to provide strength to the parallel biaxial hinges (34) and (35) and the connecting rod (36), the parallel biaxial hinges (34) and (35) and the connecting rod (36) are preferably made of metal.

図４に示すように、平行２軸ヒンジ(34)(35)には夫々内向きに第１ヒンジ軸(31)及び第２ヒンジ軸(32)が平行２軸ヒンジ(34)(35)に対して回動可能に突設されており、第１ヒンジ軸(31)は第１筐体(10)に、第２ヒンジ軸(32)は第２筐体(20)に夫々固定されている。
第１ヒンジ軸(31)及び第２ヒンジ軸(32)どうしを夫々結ぶ軸線Ａ１、Ａ２は互いに平行である。
なお、平行２軸ヒンジ(34)(35)にヒンジ軸(31)(32)を固定して、ヒンジ軸(31)(32)を筐体(10)(20)に対して回動可能となるように配備することもできる。 As shown in FIG. 4, the first and second hinge shafts 31 and 32 are inwardly connected to the parallel two-axis hinges 34 and 35, respectively. The first hinge shaft (31) is fixed to the first housing (10), and the second hinge shaft (32) is fixed to the second housing (20). .
Axis lines A1 and A2 connecting the first hinge axis (31) and the second hinge axis (32) are parallel to each other.
The hinge shafts (31) and (32) are fixed to the parallel biaxial hinges (34) and (35), and the hinge shafts (31) and (32) can be rotated with respect to the housing (10) and (20). It can also be deployed.

第１ヒンジ軸(31)と第２ヒンジ軸(32)は、カム等(図示せず)により連繋し、筺体(10)(20)の相対的な回転角度に拘わらず、連結杆(36)が両筺体(10)(20)の開き角度に対して中間の角度を維持できるようにすることがより望ましい。   The first hinge shaft (31) and the second hinge shaft (32) are connected by a cam or the like (not shown), and the connecting rod (36) regardless of the relative rotation angle of the housings (10) and (20). It is more desirable to maintain an intermediate angle with respect to the opening angle of both the casings (10) and (20).

平行２軸ヒンジ(34)(35)は連結杆(36)によって互いに回転方向にズレることはなく、また、連結杆(36)の長さ方向の間隔も維持されているから、平行２軸ヒンジ(34)(35)の各ヒンジ軸(31)(32)は、筐体(10)(20)への侵入長さＤが、筐体(10)(20)を夫々脱落することなく支持できる長さ以上であれば足り、平行２軸ヒンジ(34)(35)の全体的な幅を、図３に示すように、図８に比して可及的に短くすることができる。   The parallel biaxial hinges (34) and (35) are not displaced in the rotational direction by the connecting rod (36), and the distance in the longitudinal direction of the connecting rod (36) is maintained. The hinge shafts (31) and (32) of (34) and (35) can support the casings (10) and (20) without dropping off the casings (10) and (20), respectively, by the penetration length D into the casings (10) and (20). The overall width of the parallel biaxial hinges (34) and (35) can be made as short as possible as compared with FIG. 8, as shown in FIG.

これにより、タッチパネルアッセンブリ(60)(60)の左右両側の幅Ｗを可及的に短くすることができ、筺体(10)(20)の幅を狭くできるから、デザインのバリエーションも増大できる。
特に、筺体(10)(20)の左右の幅Ｗを短くしても、平行２軸ヒンジ(34)(35)はスクリーン(61)(61)の左右に設けることができるから、両スクリーン(61)(61)を開状態において各筺体(10)(20)の対向する端部まで設けることができ、これらスクリーン(61)(61)を１つの画面として活用できる利点がある。 As a result, the width W on the left and right sides of the touch panel assembly (60) (60) can be shortened as much as possible, and the width of the housing (10) (20) can be narrowed, thereby increasing design variations.
In particular, even if the left and right widths W of the housings (10) and (20) are shortened, the parallel biaxial hinges (34) and (35) can be provided on the left and right of the screens (61) and (61). 61) (61) can be provided up to the opposite ends of the respective casings (10), (20) in the open state, and there is an advantage that these screens (61), (61) can be utilized as one screen.

然して、両筺体(10)(20)は、各平行２軸ヒンジ(34)(35)の夫々対向する第１ヒンジ軸(31)を第１筺体(10)、対向する第２ヒンジ軸(32)を第２筺体(20)に嵌めることにより、相対的に開閉可能に連結することができる。   However, the two housings (10) and (20) are configured such that the first hinge shaft (31) facing each of the parallel biaxial hinges (34) and (35) is the first housing (10) and the second hinge shaft (32) facing each other. ) Can be connected to the second casing (20) so as to be relatively openable and closable.

上記のように、ヒンジ軸(31)(32)は、夫々連結杆(36)により互いに連結された平行２軸ヒンジ(34)(35)から突設され、捻り方向の力に強く、各ヒンジ軸(31)(32)の軸線Ａ１、Ａ２は平行な状態を維持できるから、平行２軸ヒンジ(34)(35)の筺体(10)(20)への侵入長さＤが短くても、捻り方向にガタツくことを防止できる。   As described above, the hinge shafts (31) and (32) protrude from the parallel biaxial hinges (34) and (35) connected to each other by the connecting rod (36), and are strong against the force in the twisting direction. Since the axes A1 and A2 of the shafts (31) and (32) can maintain a parallel state, even if the penetration length D of the parallel biaxial hinges (34) and (35) into the housing (10) and (20) is short, It is possible to prevent rattling in the twisting direction.

また、連結杆(36)を例えば電子機器(１)の閉状態における両筐体(10)(20)の厚さと略一致する板状に構成することで、連結杆(36)を本の背の如き外観とすることができ、折り畳み式電子機器(１)のデザイン性を向上させることができる。   Further, the connecting rod (36) is configured in a plate shape that substantially matches the thickness of the two housings (10) and (20) in the closed state of the electronic device (1), for example. The design of the foldable electronic device (1) can be improved.

なお、両平行２軸ヒンジ(34)(35)のヒンジ軸(31)(32)を直接筺体(10)(20)に取り付けた場合、閉状態と開状態との間で筺体(10)(20)を相対的に開閉したときに、筺体(10)(20)の端面どうしが衝突することがある。特に、上記のようにスクリーン(60)を筺体(10)(20)の端面まで拡大して配置した場合には、スクリーン(60)どうしが擦り合って傷等の原因となる虞がある。   When the hinge shafts (31) and (32) of the two parallel biaxial hinges (34) and (35) are directly attached to the housing (10) and (20), the housing (10) ( When the 20) is relatively opened and closed, the end faces of the housings (10) and (20) may collide with each other. In particular, when the screen (60) is arranged up to the end faces of the casings (10) and (20) as described above, the screens (60) may rub against each other and cause damage or the like.

このため、図５及び図６に示す如く、一方のヒンジ軸(図示及び以下では第２筺体(20)に連結される第２ヒンジ軸(32))は、筺体(図示及び以下では第２筺体(20))に対してスライド可能な左右一対のスライド部材(41)を介して、筺体に接続することが望ましい。   For this reason, as shown in FIGS. 5 and 6, one hinge shaft (the second hinge shaft (32) connected to the second housing (20) in the drawings and below) is connected to the housing (the second housing in the drawings and below). It is desirable to connect to the housing via a pair of left and right slide members (41) that can slide relative to (20)).

スライド部材(41)は、一端が平行２軸ヒンジ(34)(35)の各第２ヒンジ軸(32)に嵌装され、長手方向に伸び、他端近傍に第２ヒンジ軸(32)と平行な軸部材(42)を突設して構成することができる。
スライド部材(41)は、第２筺体(20)の両側に形成された溝(23)にスライド可能に嵌まっており、第２筺体(20)に対して第２ヒンジ軸(32)方向に往復移動可能となっている。
また、前記軸部材(42)は、溝(23)の側面に形成された長孔状の軸受け(29)に係合しており、スライド部材(41)は、第２筐体(20)に対して軸部材(42)回りの回転を許容されている。 One end of the slide member (41) is fitted to each of the second hinge shafts (32) of the parallel biaxial hinges (34) and (35), extends in the longitudinal direction, and the second hinge shaft (32) is disposed in the vicinity of the other end. A parallel shaft member (42) can be provided in a projecting manner.
The slide member (41) is slidably fitted in grooves (23) formed on both sides of the second casing (20), and is in the direction of the second hinge shaft (32) with respect to the second casing (20). It can move back and forth.
The shaft member (42) is engaged with a long hole bearing (29) formed on the side surface of the groove (23), and the slide member (41) is attached to the second housing (20). On the other hand, rotation around the shaft member (42) is allowed.

図６に示す如く、第１筐体(10)はフロントキャビネット(11)とバックキャビネット(12)とを互いに接合して構成され、第２筐体(20)はフロントキャビネット(21)とバックキャビネット(22)とを互いに接合して構成されている。   As shown in FIG. 6, the first casing (10) is configured by joining a front cabinet (11) and a back cabinet (12) to each other, and the second casing (20) is a front cabinet (21) and a back cabinet. (22) are joined together.

図６の如く、帯板部材(45)には、スライド部材(41)(41)の突出方向へ左右一対の舌片(46)(46)が突設され、両舌片(46)(46)と第２筐体(20)のフロントキャビネット(21)との間には、それぞれトーションバネからなる左右一対の第１スプリング(43)(43)が介在している。
なお、図５及び図６には、第１スプリング(43)の自由状態(43a)と、第１スプリング(43)が帯板部材(45)の舌片(46)と第２筐体(20)のフロントキャビネット(21)との間に圧縮されて介在している圧縮状態(43b)とを、それぞれ実線で描いている。 As shown in FIG. 6, the strip member (45) is provided with a pair of left and right tongues (46, 46) projecting in the protruding direction of the slide members (41, 41). A pair of left and right first springs (43) and (43) each consisting of a torsion spring are interposed between the front cabinet (21) of the second casing (20).
5 and 6, the free state (43a) of the first spring (43) and the tongue (46) of the strip plate member (45) and the second casing (20) ) In a compressed state (43b) interposed between the front cabinet (21) and the front cabinet (21).

また、図６の如く第２筐体(20)のフロントキャビネット(21)には、左右一対のコイルバネからなる第２スプリング(44)(44)が設置され、各第２スプリング(44)の一方の端部が第２筐体(20)のフロントキャビネット(21)に連結されると共に、各第２スプリング(44)の他方の端部が各スライド部材(41)に連結されている。   Further, as shown in FIG. 6, the front cabinet (21) of the second housing (20) is provided with second springs (44) and (44) comprising a pair of left and right coil springs, and one of the second springs (44). Is connected to the front cabinet (21) of the second housing (20), and the other end of each second spring (44) is connected to each slide member (41).

この結果、図７(ａ)(ｂ)に模式的に示すように、第１スプリング(43)と第２スプリング(44)が第２筐体(20)をスライド部材(41)に対して付勢し、第１スプリング(43)によって、軸Ａ３回りに第２筐体(20)の開き方向と同じ回転方向(時計方向)に回転させる付勢力Ｔが得られると共に、第２スプリング(44)によって第２筐体(20)をヒンジ軸Ａ２に接近させる方向の付勢力Ｆが得られる。   As a result, as schematically shown in FIGS. 7 (a) and 7 (b), the first spring (43) and the second spring (44) attach the second housing (20) to the slide member (41). The first spring (43) provides an urging force T that rotates around the axis A3 in the same rotational direction (clockwise) as the opening direction of the second housing (20), and the second spring (44). As a result, an urging force F in a direction in which the second casing (20) is brought closer to the hinge axis A2 is obtained.

従って、図７(ａ)に示すデフォルト状態から、図７(ｂ)の如くスライド部材(41)に対して第２筐体(20)がヒンジ軸Ａ２から離間すると共に、軸Ａ３回りに閉じ方向に回転して、第１スプリング(43)と第２スプリング(44)が弾性変形したとき、第１スプリング(43)の付勢力Ｔと第２スプリング(44)の付勢力Ｆによって、第２筐体(20)は、図７(ａ)に示すデフォルト状態へ向けて付勢されることになる。   Accordingly, from the default state shown in FIG. 7A, the second housing 20 is separated from the hinge shaft A2 with respect to the slide member 41 as shown in FIG. When the first spring (43) and the second spring (44) are elastically deformed, the second casing is caused by the biasing force T of the first spring (43) and the biasing force F of the second spring (44). The body (20) is biased toward the default state shown in FIG. 7 (a).

上記折り畳み式電子機器(１)においては、図１に示す閉状態で、第２筐体(20)の内面を第１筐体(10)の内面と僅かな隙間をおいて対向させると共に、第２筐体(20)をヒンジ機構(30)に対して最接近させたデフォルト状態が設定される一方、図２に示す開状態では、第１筐体(10)の内面と第２筐体(20)の内面を同一平面上に揃えると共に、第２筐体(20)をヒンジ機構(30)に対して最接近させたデフォルト状態が設定される。
従って、図１に示す閉状態では、第２筐体(20)を第１筐体(10)上に正確に重ね合わせることができ、図２に示す開状態では、第１筐体(10)のスクリーン(61)と第２筐体(20)のスクリーン(61)とを僅かな間隔Ｇをおいて接近させて、両スクリーン(61)(61)に跨って１つの大きな画像を表示したときの画像の連続性を良好なものとすることができる。 In the foldable electronic device (1), the inner surface of the second housing (20) is opposed to the inner surface of the first housing (10) with a slight gap in the closed state shown in FIG. While the default state in which the two cases (20) are brought closest to the hinge mechanism (30) is set, in the open state shown in FIG. 2, the inner surface of the first case (10) and the second case ( The default state in which the inner surface of 20) is aligned on the same plane and the second casing (20) is closest to the hinge mechanism (30) is set.
Accordingly, in the closed state shown in FIG. 1, the second housing (20) can be accurately superimposed on the first housing (10). In the open state shown in FIG. When a large image is displayed across both screens (61) and (61) by bringing the screen (61) and the screen (61) of the second housing (20) closer to each other with a slight gap G The continuity of the images can be improved.

さらに、第１筐体(10)と第２筐体(20)の開閉過程では、第１筐体(10)に対するスライド部材(41)の回動と、スライド部材(41)に対する第２筐体(20)の回転及び往復移動とによって、デフォルト状態からのずれを吸収すると共に、第１スプリング(43)及び第２スプリング(44)によってデフォルト状態へ戻す付勢力を発生させるので、両筐体(10)(20)の端部どうしを無理なく当接させてスムーズな開閉動作を実現することができる。   Further, in the opening and closing process of the first casing (10) and the second casing (20), the rotation of the slide member (41) with respect to the first casing (10) and the second casing with respect to the slide member (41). The rotation and reciprocation of (20) absorbs the deviation from the default state and generates a biasing force to return to the default state by the first spring (43) and the second spring (44). 10) The end portions of (20) can be brought into contact with each other without difficulty to realize a smooth opening / closing operation.

なお、本発明の各部構成は上記実施の形態に限らず、特許請求の範囲に記載の技術的範囲内で種々の変形が可能である。例えば、第１筐体(10)と第２筐体(20)とを入れ替えた構成、即ち第１筐体(10)にスライド部材(41)を連結した構成に本発明を実施することも可能である。   In addition, each part structure of this invention is not restricted to the said embodiment, A various deformation | transformation is possible within the technical scope as described in a claim. For example, the present invention can be implemented in a configuration in which the first casing (10) and the second casing (20) are interchanged, that is, a configuration in which the slide member (41) is connected to the first casing (10). It is.

勿論、開状態で両筐体(10)(20)を同一平面上で互いに最接近させるような上記実施の形態に限らず、単に開状態で両筐体(10)(20)の表面を同一面上に揃えるだけのヒンジ機構の構成に本発明を実施することも可能である。   Of course, the present invention is not limited to the above embodiment in which both housings (10) and (20) are brought closest to each other on the same plane in the open state, but the surfaces of both housings (10) and (20) are the same in the open state. It is also possible to implement the present invention in a configuration of a hinge mechanism that is only aligned on the surface.
