Description

本発明は、固定電話機に関する。 The present invention relates to a fixed telephone.

固定電話機は、机、棚、専用台などに設置される電話機である。固定電話機を設置する場合、ボタンの周辺に配置される画面、文字、記号などを見易くし、ボタン操作を容易にするために、ボタン、画面などが配置されたインタフェース面を、設置面に対して傾斜させることがある。 A fixed telephone is a telephone installed on a desk, a shelf, a dedicated stand or the like. When installing a fixed telephone, in order to make it easier to see the screens, characters, symbols, etc. that are placed around the buttons, and to facilitate button operations, the interface surface on which buttons, screens, etc. are placed May be tilted.

例えば特許文献１には、電話機本体の底面に取り付けられて、電話機の設置面に対するインタフェース面の傾斜角度を使いやすい角度に設定する電話機のインタフェース面の傾斜角度可変補助台が開示されている。「電話機本体」、「設置面」、「インタフェース面」のそれぞれは、特許文献１では「電話機筐体」、「据え付け面」、「操作面」と称される。 For example, Patent Document 1 discloses a variable angle tilt auxiliary table for a telephone interface surface that is attached to the bottom surface of the telephone body and sets the inclination angle of the interface surface with respect to the telephone installation surface to an easy-to-use angle. The “telephone body”, “installation surface”, and “interface surface” are referred to as “telephone housing”, “installation surface”, and “operation surface” in Patent Document 1, respectively.

特許文献１に記載の傾斜角度可変補助台では、電話機本体の底面側部材に着脱自在に取り付けられるアダプタ部品が基台上に配置される。基台には、アダプタ部品上の半円柱体に対向する位置に半円形断面の凹溝を備えている。半円柱体にはその半円周に沿うように案内溝が設けられている。凹溝内に半円柱体が嵌合された状態で半円柱体は凹溝内で案内溝の方向に沿って往復回動可能になるように構成されている。半円柱体の表面と凹溝の内壁面とに、それぞれ、設けられたローレット溝部と突起部とにより、固定電話機のインタフェース面が任意所望の傾斜角度に設定されるように構成されている。 In the tilt angle variable auxiliary base described in Patent Document 1, an adapter component that is detachably attached to a bottom surface side member of the telephone body is disposed on the base. The base is provided with a groove having a semicircular cross section at a position facing the semicylindrical body on the adapter part. The semi-cylindrical body is provided with guide grooves along the semicircular circumference. The semi-cylindrical body is configured to be reciprocally rotatable along the direction of the guide groove in the concave groove with the semi-cylindrical body fitted in the concave groove. The surface of the semi-cylindrical body and the inner wall surface of the concave groove are configured so that the interface surface of the fixed telephone is set to an arbitrary desired inclination angle by the knurled groove and the protrusion provided respectively.

特開２００４−１９４０９０号公報JP 2004-194090 A

特許文献１に記載の傾斜角度可変補助台では、基台上に配置されるアダプタ部品が電話機本体に取り付けられ、基台が設置面に接することで電話機筐体が設置される。すると、特許文献１に記載の傾斜角度可変補助台を用いる場合、基台が設置面において占める領域が、固定電話機が設置面において占める領域となるので、その面積は、インタフェース面の傾斜角にかかわらず一定となる。 In the tilt angle variable auxiliary base described in Patent Document 1, an adapter component arranged on the base is attached to the telephone body, and the telephone casing is installed by the base contacting the installation surface. Then, when the tilt angle variable auxiliary base described in Patent Document 1 is used, the area occupied by the base on the installation surface is the area occupied by the fixed telephone on the installation surface, and therefore the area depends on the inclination angle of the interface surface. It becomes constant.

しかしながら、一般的に、電話機本体を安定して支持するために必要な面積は、インタフェース面の傾斜角に応じて異なる。すなわち、電話機本体を安定して支持するには、固定電話機が設置面において占める領域の面積は、通常、インタフェース面の傾斜角が小さい程大きくする必要がある。その一方で、設置面を有効に活用するには、固定電話機が設置面において占める領域の面積を小さくすることが望ましい。 However, in general, the area required to stably support the telephone body varies depending on the inclination angle of the interface surface. That is, in order to stably support the telephone body, it is usually necessary to increase the area of the area occupied by the fixed telephone on the installation surface as the inclination angle of the interface surface is smaller. On the other hand, in order to effectively use the installation surface, it is desirable to reduce the area of the area occupied by the fixed telephone on the installation surface.

本発明は、上記の事情に鑑みてなされたものであって、インタフェース面の傾斜角が調整される電話機本体を安定的に支持しつつ、固定電話機の設置面の有効活用を図ることが可能な固定電話機を提供することを目的とする。 The present invention has been made in view of the above circumstances, and can effectively use the installation surface of the fixed telephone while stably supporting the telephone body in which the inclination angle of the interface surface is adjusted. An object is to provide a fixed telephone.

In the following description, terms representing front, back, up, down, left, and right directions are used for explanation and are not intended to limit the present invention.

（実施の形態１）
本発明の実施の形態１に係る固定電話機１００は、机、棚、専用台などに設置される電話機である。固定電話機１００は、斜視図である図１に示すように、電話機本体１０１と、２つの脚部１０２とを備える。以下では、「固定電話機１００」、「電話機本体１０１」のそれぞれを単に「電話機１００」、「本体１０１」とも表記する。 (Embodiment 1)
The fixed telephone 100 according to the first embodiment of the present invention is a telephone installed on a desk, a shelf, a dedicated stand or the like. As shown in FIG. 1 which is a perspective view, the fixed telephone 100 includes a telephone main body 101 and two legs 102. Hereinafter, “fixed telephone 100” and “telephone main body 101” are also simply referred to as “telephone 100” and “main body 101”, respectively.

本体１０１は、筐体１０３と、受話器１０４とを有する。 The main body 101 includes a housing 103 and a receiver 104.

筐体１０３は、図示しない各種の回路基板などが内部に収容される中空の部材であって、樹脂などを材料として作られる。筐体１０３には、接続配線１０５を介して受話器１０４が接続されている。 The housing 103 is a hollow member in which various circuit boards (not shown) are accommodated, and is made of resin or the like. A receiver 104 is connected to the housing 103 via a connection wiring 105.

筐体１０３は、図１及び筐体１０３の左側面図である図２に示すように、ユーザ・インタフェースが設けられるインタフェース面１０６と、電話機１００が設置される面である設置面１０７に接する本体接地部１０８と、脚部１０２が取り付けられる脚取付部１０９とを有する。 As shown in FIG. 1 and FIG. 2 which is a left side view of the housing 103, the housing 103 is a main body that is in contact with the interface surface 106 on which the user interface is provided and the installation surface 107 on which the telephone 100 is installed. It has the grounding part 108 and the leg attachment part 109 to which the leg part 102 is attached.

インタフェース面１０６には、ユーザが操作する複数のボタン１１０、ユーザが情報を閲覧するための液晶画面１１１、印刷された文字や記号など、電話機１００のユーザとのインタフェースが設けられる面である。本実施の形態に係るインタフェース面は、例えばその中心の法線方向から見て、左右が短い略矩形をなす。 The interface surface 106 is provided with an interface with the user of the telephone 100 such as a plurality of buttons 110 operated by the user, a liquid crystal screen 111 for the user to browse information, and printed characters and symbols. The interface surface according to the present embodiment has, for example, a substantially rectangular shape with short left and right when viewed from the normal direction of the center.

本体接地部１０８は、本体１０１のうちの設置面１０７に接する部分であって、本体１０１の概ね下端に位置する。本実施の形態に係る本体接地部１０８は、左右に概ね直線状に延びており、図２に示すように、本体１０１の前端よりもやや後方に位置している。 The main body grounding part 108 is a part of the main body 101 that is in contact with the installation surface 107, and is located substantially at the lower end of the main body 101. The main body grounding portion 108 according to the present embodiment extends substantially linearly to the left and right, and is located slightly behind the front end of the main body 101 as shown in FIG.

脚取付部１０９は、脚部１０２が取り付けられる部位であって、脚部１０２が回転軸Ｏを中心として回転できるように取り付けられる。回転軸Ｏは、設置面１０７及びインタフェース面１０６に平行に延びる直線であって、本実施の形態では左右に延びる。 The leg attachment portion 109 is a portion to which the leg portion 102 is attached, and is attached so that the leg portion 102 can rotate around the rotation axis O. The rotation axis O is a straight line extending in parallel with the installation surface 107 and the interface surface 106, and extends in the left and right direction in the present embodiment.

本実施の形態では、脚取付部１０９は、後述するように脚部１０２が有する本体取付部１１３の軸部材が嵌合する孔を形成する。脚取付部１０９が形成する孔は、回転軸方向に延びる。ここで、回転軸方向とは、回転軸Ｏに沿った方向であり、本実施の形態では左右方向である。 In the present embodiment, the leg mounting portion 109 forms a hole into which the shaft member of the main body mounting portion 113 included in the leg portion 102 is fitted, as will be described later. The hole formed by the leg attachment portion 109 extends in the rotation axis direction. Here, the rotation axis direction is a direction along the rotation axis O, and is the left-right direction in the present embodiment.

２つの脚部１０２は、電話機１００が設置面１０７に設置された場合に、本体１０１を後方から支持する部材である。脚部１０２の各々は、回転軸Ｏを中心として回転可能に筐体１０３に取り付けられ、インタフェース面１０６とは反対の筐体背面１１２から後方斜め下へ向けて延びる。 The two legs 102 are members that support the main body 101 from the rear when the telephone 100 is installed on the installation surface 107. Each of the legs 102 is attached to the housing 103 so as to be rotatable about the rotation axis O, and extends rearward and obliquely downward from the housing back surface 112 opposite to the interface surface 106.

詳細には、２つの脚部１０２は、左右に並べて筐体１０３に取り付けられており、例えば、筐体１０３の左端近傍と右端近傍とに左右対称となる位置に取り付けられている。なお、脚部１０２は、１つであってもよく、３つ以上であってもよい。１つの場合、脚部１０２は、例えば筐体１０３の左右の中央に取り付けられるとよい。 Specifically, the two leg portions 102 are attached to the housing 103 side by side on the left and right sides, and are attached to, for example, symmetrical positions in the vicinity of the left end and the right end of the housing 103. In addition, the leg part 102 may be one and may be three or more. In one case, the leg 102 may be attached to the left and right center of the housing 103, for example.

脚部１０２の各々は、本体取付部１１３と、脚接地部１１４と、延在部１１５とを有する。 Each of the leg portions 102 has a main body attaching portion 113, a leg grounding portion 114, and an extending portion 115.

本体取付部１１３は、回転軸Ｏを中心として回転可能に脚部１０２を本体１０１に取り付ける部位である。本実施の形態に係る本体取付部１１３は、左右に延びる延柱状の軸部材であり、上述のように脚取付部１０９に嵌合する。 The main body attaching portion 113 is a portion for attaching the leg portion 102 to the main body 101 so as to be rotatable about the rotation axis O. The main body attachment portion 113 according to the present embodiment is a pillar-shaped shaft member extending left and right, and is fitted to the leg attachment portion 109 as described above.

本体取付部１１３と脚取付部１０９とは、例えば本体取付部１１３の周面に設けられたゴムなどの摩擦係数が大きくかつ弾性を有する部材を介して接することで、任意の角度で固定される。ここでの固定は、側方から見たインタフェース面１０６に対する脚部１０２の角度を変更することができ、かつ、電話機１００を設置した場合に、側方から見たインタフェース面１０６に対する脚部１０２の角度が電話機１００の重みによって変化しない程度にその角度を保持できることをいう。なお、本体取付部１１３と脚取付部１０９とを固定する方法は、ここで例示した方法に限られず、例えばネジ止めなどが採用されてもよい。 The main body attaching portion 113 and the leg attaching portion 109 are fixed at an arbitrary angle by contacting with each other through a member having a large friction coefficient such as rubber provided on the peripheral surface of the main body attaching portion 113 and having elasticity. . The fixing here can change the angle of the leg portion 102 with respect to the interface surface 106 viewed from the side, and when the telephone 100 is installed, the leg portion 102 with respect to the interface surface 106 viewed from the side surface can be changed. This means that the angle can be maintained to the extent that the angle does not change depending on the weight of the telephone 100. In addition, the method of fixing the main body attaching part 113 and the leg attaching part 109 is not restricted to the method illustrated here, For example, screwing etc. may be employ | adopted.

脚接地部１１４は、設置面１０７に接する部位である。本実施の形態では、脚接地部１１４は曲面であり、図２に示すように、側方から見て下へ突き出した曲線をなす。そして、脚接地部１１４は、側方から見た場合、設置面１０７と概ね点で接している。 The leg grounding part 114 is a part in contact with the installation surface 107. In the present embodiment, the leg ground contact portion 114 is a curved surface, and forms a curve protruding downward as seen from the side as shown in FIG. The leg ground contact portion 114 is in contact with the installation surface 107 at a point when viewed from the side.

脚接地部１１４のうち、設置面１０７と接する点の位置は、図３（ａ）〜図６（ａ）に示すように、側方から見たインタフェース面１０６に対する脚部１０２の角度に応じて変化する。図３（ａ）〜図６（ａ）は、本体１０１の傾斜角が異なる状態での電話機１００の左側面図である。なお、図３（ａ）〜図６（ａ）では、図を簡明にするため、受話器１０４を省略している。 As shown in FIGS. 3A to 6A, the position of the leg ground contact portion 114 that contacts the installation surface 107 depends on the angle of the leg portion 102 with respect to the interface surface 106 as viewed from the side. Change. FIG. 3A to FIG. 6A are left side views of the telephone 100 in a state where the inclination angle of the main body 101 is different. In FIG. 3A to FIG. 6A, the handset 104 is omitted for the sake of simplicity.

延在部１１５は、本体取付部１１３と脚接地部１１４との間で延びる部分である。 The extending portion 115 is a portion extending between the main body attaching portion 113 and the leg grounding portion 114.

本実施の形態に係る脚部１０２の各々は、図２及び図３（ａ）〜図６（ａ）に示すように、側方から見たインタフェース面１０６に対する角度にかかわらず、第１距離Ｌ１と第２距離Ｌ２と第３距離Ｌ３とが等しくなる位置に設けられる。 As shown in FIGS. 2 and 3A to 6A, each of the legs 102 according to the present embodiment has a first distance L1 regardless of the angle with respect to the interface surface 106 as viewed from the side. And the second distance L2 and the third distance L3 are equal to each other.

第１距離Ｌ１は、設置面に垂直な方向（例えば、上方）から見て、本体１０１の後端部１１６と回転軸Ｏとの間の前後方向の距離である。本実施の形態の前後方向は、設置面に垂直な方向から見て、回転軸Ｏに垂直な方向に相当する。 The first distance L1 is a distance in the front-rear direction between the rear end portion 116 of the main body 101 and the rotation axis O when viewed from a direction perpendicular to the installation surface (for example, upward). The front-rear direction of the present embodiment corresponds to a direction perpendicular to the rotation axis O when viewed from a direction perpendicular to the installation surface.

本体１０１の後端部１１６は、回転軸Ｏに垂直な方向に位置する本体１０１の端部のうち、回転軸Ｏを挟んで本体接地部１０８とは反対側の端部である。言い換えると、本体１０１の後端部１１６は、回転軸方向から見て、本体接地部１０８から回転軸Ｏを通って延びる直線ＬＮ上に位置する本体１０１の端部である。すなわち、回転軸Ｏは、本体接地部１０８及び本体１０１の後端部１１６を含む平面上にある。 The rear end portion 116 of the main body 101 is an end portion on the opposite side of the main body grounding portion 108 across the rotation axis O among the end portions of the main body 101 positioned in a direction perpendicular to the rotation axis O. In other words, the rear end portion 116 of the main body 101 is an end portion of the main body 101 located on a straight line LN extending from the main body grounding portion 108 through the rotation axis O when viewed from the rotation axis direction. That is, the rotation axis O is on a plane including the main body grounding portion 108 and the rear end portion 116 of the main body 101.

第２距離Ｌ２は、設置面に垂直な方向から見て、脚接地部１１４と回転軸Ｏとの間の前後方向の距離である。詳細には、本実施の形態では脚接地部１１４は上述の通り、回転軸方向から見て長さを有する曲線を形成するところ、第２距離Ｌ２は、設置面に垂直な方向から見て、脚接地部１１４の後端部Ｅと回転軸Ｏとの間の距離である。 The second distance L2 is a distance in the front-rear direction between the leg grounding portion 114 and the rotation axis O when viewed from a direction perpendicular to the installation surface. Specifically, in the present embodiment, as described above, the leg ground contact portion 114 forms a curve having a length when viewed from the rotation axis direction, and the second distance L2 is viewed from a direction perpendicular to the installation surface. This is the distance between the rear end E of the leg ground contact portion 114 and the rotation axis O.

第３距離Ｌ３は、設置面１０７に垂直な方向から見て、本体接地部１０８と回転軸Ｏとの間の前後方向の距離である。 The third distance L3 is a distance in the front-rear direction between the main body grounding portion 108 and the rotation axis O when viewed from the direction perpendicular to the installation surface 107.

ここで上述の通り、回転軸Ｏは、本体接地部１０８及び本体１０１の後端部１１６を含む平面上にあり、かつ、第１距離Ｌ１と第３距離Ｌ３が等しい。このことは、回転軸Ｏが、本体接地部１０８及び本体１０１の後端部１１６を含む平面上にあり、かつ、設置面１０７に垂直な方向と回転軸方向とのいずれから見ても、本体接地部１０８と本体１０１の後端部１１６との中間に位置することを意味する。 Here, as described above, the rotation axis O is on a plane including the main body grounding portion 108 and the rear end portion 116 of the main body 101, and the first distance L1 and the third distance L3 are equal. This is because the rotation axis O is on a plane including the main body grounding portion 108 and the rear end portion 116 of the main body 101, and the main body is seen from either the direction perpendicular to the installation surface 107 or the rotation axis direction. This means that it is located between the grounding portion 108 and the rear end portion 116 of the main body 101.

これまで、本発明の一実施の形態に係る電話機１００の構成について説明した。ここから、本実施の形態に係る電話機１００の動作について、図３〜図７を参照して説明する。 Heretofore, the configuration of the telephone 100 according to the embodiment of the present invention has been described. From here, operation | movement of the telephone 100 which concerns on this Embodiment is demonstrated with reference to FIGS.

図３（ａ）〜図６（ａ）は、上述の通り、本体１０１の傾斜角が異なる状態での、受話器１０４を図示省略した電話機１００の左側面図である。図３（ｂ）〜図６（ｂ）は、それぞれ、図３（ａ）〜図６（ａ）に示す各状態で左方から見た電話機１００をモデル化した図である。 3A to 6A are left side views of the telephone 100 in which the handset 104 is omitted in the state where the inclination angle of the main body 101 is different as described above. FIGS. 3B to 6B are diagrams in which the telephone 100 viewed from the left in each state shown in FIGS. 3A to 6A is modeled.

本体１０１の傾斜角は、設置面１０７に対するインタフェース面１０６の傾斜角に相当するところ、この傾斜角は、例えば、側方から見たインタフェース面１０６に対する脚部１０２の角度、設置面１０７に対する直線ＬＮの角度θに対応づけることができる。 The inclination angle of the main body 101 corresponds to the inclination angle of the interface surface 106 with respect to the installation surface 107. This inclination angle is, for example, the angle of the leg 102 with respect to the interface surface 106 viewed from the side, or the straight line LN with respect to the installation surface 107. Can be associated with the angle θ.

図３〜図６に示す電話機１００の状態は、それぞれ、左方から見て設置面１０７に対する直線ＬＮの角度θがα（度）、β（度）、γ（度）、δ（度）である状態である。 3 to 6, the angles θ of the straight line LN with respect to the installation surface 107 when viewed from the left are α (degrees), β (degrees), γ (degrees), and δ (degrees), respectively. It is a certain state.

角度θがα（度）である場合、図３に示すように、本体１０１の後端部１１６、回転軸Ｏ、脚接地部１１４の後端部Ｅ、本体接地部１０８、直線ＬＮのそれぞれを、後端部１１６＿α、回転軸Ｏ＿α、後端部Ｅ＿α、本体接地部１０８＿α、直線ＬＮ＿αとする。この場合の、第１距離Ｌ１、第２距離Ｌ２、第３距離Ｌ３のそれぞれを、Ｌ１＿α、Ｌ２＿α、Ｌ３＿αとすると、Ｌ１＿α、Ｌ２＿α、Ｌ３＿αは、等しい。 When the angle θ is α (degrees), as shown in FIG. 3, each of the rear end portion 116 of the main body 101, the rotation axis O, the rear end portion E of the leg ground contact portion 114, the main body ground contact portion 108, and the straight line LN The rear end portion 116_α, the rotation axis O_α, the rear end portion E_α, the main body grounding portion 108_α, and the straight line LN_α.

これまで説明したように、本実施の形態では、電話機１００を回転軸方向から見て、設置面１０７に対する直線ＬＮの角度θにかかわらず、言い換えると、設置面１０７に対するインタフェース面１０６の傾斜角にかかわらず、Ｌ１とＬ２の長さが等しい。また、設置面１０７に対するインタフェース面１０６の傾斜角にかかわらず、回転軸Ｏは、本体接地部１０８及び本体１０１の後端部１１６を含む平面上にあり、設置面１０７に垂直な方向から見て本体接地部１０８と本体１０１の後端部１１６との中間に位置する。 As described above, in the present embodiment, when the telephone 100 is viewed from the rotation axis direction, regardless of the angle θ of the straight line LN with respect to the installation surface 107, in other words, the inclination angle of the interface surface 106 with respect to the installation surface 107. Regardless, the lengths of L1 and L2 are equal. Regardless of the inclination angle of the interface surface 106 with respect to the installation surface 107, the rotation axis O is on a plane including the main body grounding portion 108 and the rear end portion 116 of the main body 101, and is viewed from a direction perpendicular to the installation surface 107. It is located between the main body grounding portion 108 and the rear end portion 116 of the main body 101.

これにより、図７に示すように、設置面１０７に対するインタフェース面１０６の傾斜角にかかわらず、設置面１０７に垂直な方向から見て、本体１０１の後端部１１６と脚接地部１１４の後端部Ｅとが同じ位置に位置付けられる。 Accordingly, as shown in FIG. 7, the rear end portion 116 of the main body 101 and the rear end of the leg ground contact portion 114 are viewed from the direction perpendicular to the installation surface 107 regardless of the inclination angle of the interface surface 106 with respect to the installation surface 107. The part E is positioned at the same position.

そのため、設置面１０７に垂直な方向から見て、脚接地部１１４の後端部Ｅが、本体１０１の後端部１１６よりも前方に位置する場合よりも、本体接地部１０８と脚接地部１１４の後端部Ｅとの間の距離を長くすることができる。従って、インタフェース面１０６の傾斜角が調整される本体１０１を安定的に支持することが可能になる。 Therefore, when viewed from a direction perpendicular to the installation surface 107, the main body grounding portion 108 and the leg grounding portion 114 are more than the rear end portion E of the leg grounding portion 114 positioned in front of the rear end portion 116 of the main body 101. The distance from the rear end E can be increased. Accordingly, it is possible to stably support the main body 101 in which the inclination angle of the interface surface 106 is adjusted.

また、設置面１０７に垂直な方向から見て、脚接地部１１４の後端部Ｅが、本体１０１の後端部１１６よりも後方に位置する場合よりも、電話機１００が設置面１０７において占める領域の面積を小さくすることができる。従って、インタフェース面１０６の傾斜角が調整される電話機１００の設置面１０７の有効活用を図ることが可能になる。 Further, when the rear end E of the leg ground contact portion 114 is located behind the rear end 116 of the main body 101 when viewed from the direction perpendicular to the installation surface 107, the telephone 100 occupies the area on the installation surface 107. Can be reduced. Therefore, it is possible to effectively use the installation surface 107 of the telephone 100 in which the inclination angle of the interface surface 106 is adjusted.

このように、本実施の形態に係る電話機１００によれば、インタフェース面１０６の傾斜角が調整される本体１０１を安定的に支持しつつ、電話機１００の設置面１０７の有効活用を図ることが可能になる。 As described above, according to the telephone 100 according to the present embodiment, it is possible to effectively use the installation surface 107 of the telephone 100 while stably supporting the main body 101 whose inclination angle of the interface surface 106 is adjusted. become.

例えば図２〜７に示すように、電話機１００は、しばしば、設置面１０７に垂直な壁Ｗに付けて配置されることがある。図７は、各状態の比較を容易にするため、図３（ｂ）〜図６（ｂ）を１つにまとめて表した図である。 For example, as shown in FIGS. 2 to 7, the telephone 100 is often placed on a wall W perpendicular to the installation surface 107. FIG. 7 is a diagram in which FIGS. 3 (b) to 6 (b) are combined into one to facilitate comparison of each state.

仮に、設置面１０７に垂直な方向から見て、脚接地部１１４の後端部Ｅが、本体１０１の後端部１１６よりも前方に位置する場合、本体１０１の後端部１１６を壁Ｗに接触させて電話機１００を設置することができる。しかしながら、本体接地部１０８と脚接地部１１４の後端部Ｅとの間の距離が、本実施の形態に係る電話機１００よりも短くなる。そのため、本実施の形態に係る電話機１００よりも安定性が悪くなる。 If the rear end E of the leg grounding portion 114 is positioned in front of the rear end 116 of the main body 101 when viewed from the direction perpendicular to the installation surface 107, the rear end 116 of the main body 101 is placed on the wall W. The telephone 100 can be installed in contact. However, the distance between main body grounding section 108 and rear end E of leg grounding section 114 is shorter than that of telephone 100 according to the present embodiment. Therefore, the stability is worse than that of the telephone 100 according to the present embodiment.

また、仮に、設置面１０７に垂直な方向から見て、脚接地部１１４の後端部Ｅが、本体１０１の後端部１１６よりも後方に位置する場合、本体１０１の後端部１１６を壁Ｗに接触させて電話機１００を設置することができない。本体１０１の後端部１１６と壁Ｗとの間にすき間ができる分、本体接地部１０８が前方へ位置づけられる。そのため、本実施の形態に係る電話機１００よりも設置面１０７を占める領域の面積が大きくなる。 In addition, if the rear end E of the leg grounding portion 114 is located behind the rear end 116 of the main body 101 when viewed from the direction perpendicular to the installation surface 107, the rear end 116 of the main body 101 is placed on the wall. The telephone 100 cannot be installed in contact with W. The main body grounding portion 108 is positioned forward by an amount corresponding to the gap between the rear end portion 116 of the main body 101 and the wall W. Therefore, the area of the area occupying the installation surface 107 is larger than that of the telephone 100 according to the present embodiment.

本実施の形態に係る電話機１００によれば、本体１０１の後端部１１６を壁Ｗに接触させながら、本体接地部１０８と脚接地部１１４の後端部Ｅとの間の距離を可能な限り長くすることができる。従って、インタフェース面１０６の傾斜角が調整される本体１０１を安定的に支持しつつ、電話機１００の設置面の有効活用を図ることが可能になる。 According to telephone 100 according to the present embodiment, the distance between main body grounding portion 108 and rear end portion E of leg grounding portion 114 is set as much as possible while rear end portion 116 of main body 101 is in contact with wall W. Can be long. Therefore, it is possible to effectively utilize the installation surface of the telephone 100 while stably supporting the main body 101 whose inclination angle of the interface surface 106 is adjusted.

以上、本発明の一実施の形態について説明したが、本実施の形態は、以下のように変形されてもよい。 Although one embodiment of the present invention has been described above, the present embodiment may be modified as follows.

（変形例）
延在部１１５が、その長さを調整するための長さ調整機構を含んでもよい。長さ調整機構によって、設置面１０７に対する直線ＬＮの角度θに応じて、延在部１１５の長さを調整することで、設置面１０７に対するインタフェース面１０６の傾斜角にかかわらず、Ｌ１とＬ２の長さを等しくすることができる。これにより、設置面１０７に垂直な方向から見て、本体１０１の後端部１１６と脚接地部１１４の後端部Ｅとが同じ位置に位置付けられる。 (Modification)
The extending part 115 may include a length adjusting mechanism for adjusting the length thereof. Regardless of the inclination angle of the interface surface 106 with respect to the installation surface 107, the length adjustment mechanism adjusts the length of the extending portion 115 according to the angle θ of the straight line LN with respect to the installation surface 107. The length can be made equal. Accordingly, the rear end portion 116 of the main body 101 and the rear end portion E of the leg ground contact portion 114 are positioned at the same position when viewed from the direction perpendicular to the installation surface 107.

従って、この変形例によっても実施の形態と同様に、インタフェース面１０６の傾斜角が調整される本体１０１を安定的に支持しつつ、電話機１００の設置面の有効活用を図ることが可能になる。 Therefore, according to this modification, as in the embodiment, it is possible to effectively utilize the installation surface of the telephone 100 while stably supporting the main body 101 whose inclination angle of the interface surface 106 is adjusted.

以上、本発明の一実施の形態及び変形例について説明したが、本発明は、これらに限られない。例えば、本発明は、これまで説明した実施の形態及び変形例の一部又は全部を適宜組み合わせた形態、その形態に適宜変更を加えた形態をも含む。 As mentioned above, although one Embodiment and modification of this invention were demonstrated, this invention is not limited to these.
