（１）実施の形態の概要
図１に示したように、受話部２と送話部３の外側面は半径Ｒの円柱面となっている。
受話部２と送話部３は、蝶番部４によって開閉可能に接合しており、全開時の開角度は、当接部５によって規定されている。
そして、受話部２と送話部３を全開すると、受話部２と送話部３の外側面は、中心Ｏを中心軸とし、半径Ｒの連続した円柱面を形成する。
このように、携帯電話１の外周面が凸曲面を形成しているため、倒したり、落としたりなどした場合でも、携帯電話１は、接地面上で転がり、衝撃を緩和することができる。
また、携帯電話１を開いた状態でも閉じた状態でも、外側面の曲面により携帯電話１が手のひらにフィットして感触がよいほか、落としにくくなる。 (1) Outline of Embodiment As shown in FIG. 1, the outer surfaces of the reception unit 2 and the transmission unit 3 are cylindrical surfaces having a radius R.
The receiving part 2 and the transmitting part 3 are joined so as to be opened and closed by a hinge part 4, and the opening angle when fully opened is defined by the contact part 5.
When the reception unit 2 and the transmission unit 3 are fully opened, the outer surfaces of the reception unit 2 and the transmission unit 3 form a cylindrical surface with a center R as a central axis and a radius R.
Thus, since the outer peripheral surface of the mobile phone 1 forms a convex curved surface, the mobile phone 1 can roll on the ground surface even when it is tilted or dropped, so that the impact can be reduced.
Further, whether the cellular phone 1 is opened or closed, the curved surface of the outer surface allows the cellular phone 1 to fit in the palm of the hand and feel good, and it is difficult to drop.

（２）実施の形態の詳細
図１は、本実施の形態に係る携帯電話の外観（左図は側面図、右図は正面図）を示した図である。

受話部２の内側面には、液晶パネルなどを備えた表示部６と、通話相手の音声を出力するスピーカ部８が形成されている。
一方、送話部３の内側面には、数字、文字、記号などを入力するためのキーパッド部７と、ユーザの音声を検知するマイクロフォン部９が形成されている。
また、受話部２と送話部３には、携帯電話網の基地局と通信して携帯電話機能を発揮させる各種電子装置が内蔵されている。 (2) Details of Embodiment FIG. 1 is a diagram showing an appearance (a left side is a side view and a right side is a front view) of a mobile phone according to the present embodiment.
The mobile phone 1 is configured such that the reception unit 2 and the transmission unit 3 can be opened and closed by a hinge unit 4.
A display unit 6 having a liquid crystal panel and a speaker unit 8 for outputting the voice of the other party are formed on the inner surface of the receiver unit 2.
On the other hand, a keypad unit 7 for inputting numbers, characters, symbols, and the like, and a microphone unit 9 for detecting the user's voice are formed on the inner surface of the transmitter unit 3.
The receiver 2 and transmitter 3 incorporate various electronic devices that communicate with a base station of a mobile phone network and perform a mobile phone function.

受話部２の外側面は半径Ｒ（例えば、１ｍ）の円柱面を形成しており、周方向の一端に蝶番部４が取り付けられている。
送話部３の外側面も同様に半径Ｒの円柱面を形成しており、周方向の一端に蝶番部４が取り付けられている。
このように、受話部２と送話部３には所定の曲率半径を有する外側面が形成されている。 The outer surface of the receiver 2 forms a cylindrical surface with a radius R (for example, 1 m), and a hinge 4 is attached to one end in the circumferential direction.
Similarly, the outer surface of the transmitter 3 forms a cylindrical surface with a radius R, and a hinge portion 4 is attached to one end in the circumferential direction.
As described above, the receiving unit 2 and the transmitting unit 3 are formed with outer surfaces having a predetermined radius of curvature.

受話部２、送話部３の外側面、及び蝶番部４の空間的な位置関係は、受話部２の外側面の中心軸、送話部３の外側面の中心軸、及び蝶番部４の回転軸が並行となるようになっている。
そして、受話部２と送話部３は、蝶番部４を軸として開閉できるようになっている。 The spatial positional relationship between the receiving unit 2, the outer surface of the transmitting unit 3, and the hinge unit 4 includes the center axis of the outer surface of the receiving unit 2, the central axis of the outer surface of the transmitting unit 3, and the hinge unit 4. The rotation axis is parallel.
The receiver 2 and transmitter 3 can be opened and closed with the hinge 4 as an axis.

送話部３の一端側（蝶番部４側）には、携帯電話１を開いたときに受話部２の一端側（蝶番部４側）が当接して、受話部２と送話部３の開角度を固定する当接部５が設けられており、これによって携帯電話１を全開した場合の受話部２と送話部３の角度が規定されている。
また、蝶番部４には、例えばノッチ機構などにより、受話部２と送話部３が全開状態、及び全閉状態となる角度において係止する係止手段が設けられている。
即ち、蝶番部４は、受話部２と送話部３を開閉しようとするトルクが所定値未満である場合、これ固定して開閉させず、所定値以上となる場合、固定を解除して開閉させる。 One end side (hinge part 4 side) of the receiver 2 comes into contact with one end side (hinge part 4 side) of the transmitter part 3 when the mobile phone 1 is opened. An abutting portion 5 for fixing the opening angle is provided, whereby the angle between the receiving portion 2 and the transmitting portion 3 when the cellular phone 1 is fully opened is defined.
Further, the hinge part 4 is provided with a locking means that locks the reception part 2 and the transmission part 3 at an angle at which the reception part 2 and the transmission part 3 are fully opened and fully closed by, for example, a notch mechanism.
That is, the hinge unit 4 does not open and close when the torque to open and close the receiving unit 2 and the transmitting unit 3 is less than a predetermined value. Let

そして、携帯電話１を全開にした場合の角度は、受話部２の外側面と送話部３の外側面が半径Ｒの連続した周面を形成する角度となっている。
即ち、全開の状態では、受話部２の外側面の中心軸と送話部３の外側面の中心軸は一致して中心軸Ｏとなり、これによって、携帯電話１の外側面は中心軸Ｏを中心とする半径Ｒの円柱面となる。 The angle when the cellular phone 1 is fully opened is an angle at which the outer surface of the receiver 2 and the outer surface of the transmitter 3 form a continuous circumferential surface having a radius R.
That is, in the fully opened state, the central axis of the outer surface of the receiver 2 and the central axis of the outer surface of the transmitter 3 coincide with each other to become the central axis O, whereby the outer surface of the mobile phone 1 has the central axis O. It becomes a cylindrical surface with a radius R as the center.

一方、携帯電話１を全閉状態では、受話部２の他端面１０が送話部３の他端側にある内側面１１に当接し、表示部６とキーパッド部７が対向するようになっている。更に、他端面１２と受話部２の外側面が連続した曲面を形成する。これについては次の図２で説明する。   On the other hand, when the cellular phone 1 is fully closed, the other end surface 10 of the receiver 2 abuts on the inner surface 11 on the other end of the transmitter 3, and the display unit 6 and the keypad unit 7 face each other. ing. Furthermore, the other end surface 12 and the outer surface of the receiver 2 form a continuous curved surface. This will be described with reference to FIG.

以上のように、携帯電話１は、全開の状態では、外側面が半径Ｒの周面を形成するため、机上に無造作に置いたり、落としたりした場合でも、周面で転がり、衝撃を緩和することができる。
また、携帯電話１を開いて手に持った場合、外側面の周面の曲面が手のひらにフィットし、良好な持ち味感を提供すると共に、滑りにくくなるため、落としにくくなる。 As described above, in the fully opened state, the mobile phone 1 forms a peripheral surface with a radius R on the outer surface. Therefore, even when the mobile phone 1 is placed on the desk or dropped, the mobile phone 1 rolls on the peripheral surface to alleviate the impact. be able to.
In addition, when the mobile phone 1 is opened and held in the hand, the curved surface of the outer peripheral surface fits in the palm of the hand and provides a good feeling of touch, and is less slippery and therefore difficult to drop.

なお、本実施の形態では、受話部２と送話部３の外側面の曲率半径を共に同じＲとしたが、異なる値とすることも可能である。
また、受話部２と送話部３の曲率半径を異なった値とした場合、全開時に受話部２の外側面と送話部３の外側面が滑らかに連続するように全開角度を設定すると、接地面状で滑らかに転がり、良好な衝撃干渉機能を保持することができる。
更に、本実施の形態では、受話部２と送話部３の外側面を円柱面としたが、これに限定するものではなく、周方向に垂直な方向に湾曲していたり、あるいは、斜面部分を有する形状であってもよい。 In the present embodiment, the radius of curvature of the outer side surfaces of the receiving unit 2 and the transmitting unit 3 are both set to the same R, but may be different values.
In addition, when the radius of curvature of the receiving unit 2 and the transmitting unit 3 is set to different values, when the full opening angle is set so that the outer surface of the receiving unit 2 and the outer surface of the transmitting unit 3 are smoothly continuous when fully opened, It rolls smoothly in the form of a ground plane, and a good impact interference function can be maintained.
Furthermore, in the present embodiment, the outer side surfaces of the reception unit 2 and the transmission unit 3 are cylindrical surfaces. However, the present invention is not limited to this, and is curved in a direction perpendicular to the circumferential direction, or a slope portion. It may be a shape having

図２は、携帯電話１を全閉した場合の側面を示した図である。また、図３に斜視図を示してある。
図２に示したように、携帯電話１を全閉状態にすると、送話部３の内側面１１と受話部２の他端面１０が当接し、表示部６とキーパッド部７が対面するようになっている。
なお、図を見やすくするため、図２では、他端面１０と内側面１１の間に間隙を設けてある。
そして、全閉状態では、送話部３の他端面１２と受話部２の外側面が連続した半径Ｒの円柱面を形成するようになっている。
更に、携帯電話１の先端（蝶番部４と対向する側）には、送話部３の外側面と他端面１２によって鋭角部分が形成されており、携帯電話１の両側面が凸状の曲面を有するシェル（貝）型形状となる。 FIG. 2 is a diagram showing a side view when the cellular phone 1 is fully closed. FIG. 3 is a perspective view.
As shown in FIG. 2, when the cellular phone 1 is fully closed, the inner surface 11 of the transmitter 3 and the other end surface 10 of the receiver 2 come into contact with each other so that the display unit 6 and the keypad unit 7 face each other. It has become.
In FIG. 2, a gap is provided between the other end surface 10 and the inner side surface 11 in order to make the drawing easier to see.
In the fully closed state, the other end surface 12 of the transmitter 3 and the outer surface of the receiver 2 form a continuous cylindrical surface with a radius R.
Furthermore, an acute angle portion is formed at the tip of the mobile phone 1 (the side facing the hinge portion 4) by the outer surface of the transmitter 3 and the other end surface 12, and both sides of the mobile phone 1 are convex curved surfaces. It becomes the shell (shellfish) type shape which has.

一般に、折りたたみ式携帯電話を折りたたんだ状態でポケットに入れる際には、送話部と受話部の間にできる隙間にポケットの縁が引っかかって携帯電話が開いてしまい、携帯電話の収納に失敗する場合があるが、携帯電話１は、携帯電話１の先端部分から受話部２と送話部３の当接部分がオフセットされているため、収納の際にポケットの縁に引っかかるようなことがなく、また、側面が先端を頂点として徐々にふくらむ曲面であるため円滑に収納することができる。   In general, when a folding mobile phone is folded and put into a pocket, the edge of the pocket gets stuck in the gap formed between the transmitter and receiver, and the mobile phone fails to be stored. In some cases, the mobile phone 1 is not caught on the edge of the pocket when stored because the contact portion of the receiver 2 and transmitter 3 is offset from the tip of the mobile phone 1. Also, since the side surface is a curved surface that gradually swells with the tip as the apex, it can be stored smoothly.

また、携帯電話１を閉じた状態でも側面が円柱面を有しているため、閉じた状態で机上に無造作に置いたり、落としたりした場合でも、周面で転がり、衝撃を緩和することができる。
更に、携帯電話１を閉じて手に持った場合、外側面の周面の曲面が手のひらにフィットし、良好な持ち味感を提供することができ、また、落としにくくなる。 Moreover, since the side surface has a cylindrical surface even when the cellular phone 1 is closed, even if the cellular phone 1 is placed on the desk in a closed state or dropped, it can roll on the peripheral surface and reduce the impact. .
Furthermore, when the cellular phone 1 is closed and held in the hand, the curved surface of the outer peripheral surface fits into the palm of the hand, can provide a good taste, and is difficult to drop.

以上に説明した携帯電話１において、受話部２は、所定の曲率半径（実施の形態では曲率半径Ｒ）を有する外側面が形成された第１の構成部として機能し、送話部３は、所定の曲率半径を有する外側面が形成された第２の構成部として機能している。
そして、蝶番部４は、第１の構成部（受話部２）の外側面の周方向の一端と、第２の構成部（送話部３）の外側面の周方向の一端に形成され、第１の構成部と第２の構成部を開閉可能に保持する蝶番部として機能している。
更に、図１に示した当接部５（又は当接部５と蝶番部４のノッチ機構などの係止手段の組合せ）は、第１の構成部（受話部２）と第２の構成部（送話部３）が蝶番部（蝶番部４）によって開いた場合に、第１の構成部の外側面と第２の構成部の外側面が連続した曲面を構成するように、第１の構成部と第２の構成部の開角度を固定する固定手段として機能している。 In the mobile phone 1 described above, the receiver 2 functions as a first component having an outer surface having a predetermined radius of curvature (the radius of curvature R in the embodiment), and the transmitter 3 is It functions as a second component having an outer surface having a predetermined radius of curvature.
And the hinge part 4 is formed in the end of the outer surface of the 1st structure part (receiver part 2) in the circumferential direction, and the end of the outer surface of the 2nd structure part (transmission part 3) in the circumferential direction, It functions as a hinge that holds the first component and the second component in an openable and closable manner.
Further, the contact portion 5 (or a combination of locking means such as a notch mechanism of the contact portion 5 and the hinge portion 4) shown in FIG. 1 includes a first component (the earpiece 2) and a second component. When the (sending part 3) is opened by the hinge part (hinge part 4), the first surface of the first component part and the outer surface of the second component part form a continuous curved surface. It functions as a fixing means for fixing the opening angle of the component and the second component.

また、携帯電話１では、第１の構成部（受話部２）と前記第２の構成部（送話部３）を閉じた場合に、前記第１の構成部の他端面（他端面１０）が、前記第２の構成部の内側面（内側面１１）に当接し、第１の構成部の外側面と第２の構成部の他端面（他端面１２）が連続した曲面を構成している。
なお、本実施の形態では、受話部２の他端面１０が送話部３の内側面１１に当接するように構成したが、受話部２の内側面に、送話部３の他端面１２が当接するように構成することもできる。
この場合、送話部３が第１の構成部として機能し、受話部２が第２の構成部として機能する。
更に、固定手段（当接部５）は、第１の構成部（受話部２）と第２の構成部（送話部３）が蝶番部（蝶番部４）によって開いた場合に、第１の構成部の外側面と第２の構成部の外側面が１つの中心を中心軸（中心軸Ｏ）として連続した曲面を構成するように、第１の構成部と第２の構成部の開角度を固定している。 Further, in the mobile phone 1, when the first component (receiver 2) and the second component (transmitter 3) are closed, the other end surface (the other end surface 10) of the first component. Is in contact with the inner side surface (inner side surface 11) of the second component, and forms a curved surface in which the outer surface of the first component and the other end surface (the other end surface 12) of the second component are continuous. Yes.
In the present embodiment, the other end face 10 of the receiver 2 is configured to come into contact with the inner surface 11 of the transmitter 3, but the other end face 12 of the transmitter 3 is provided on the inner face of the receiver 2. It can also comprise so that it may contact | abut.
In this case, the transmitter 3 functions as a first component, and the receiver 2 functions as a second component.
Furthermore, the fixing means (contact portion 5) is the first when the first component (receiver 2) and the second component (transmitter 3) are opened by the hinge (hinge 4). The first component and the second component are opened so that the outer surface of the component and the outer surface of the second component constitute a continuous curved surface with one center as the central axis (center axis O). The angle is fixed.

図４（ａ）は、携帯電話１の重心位置を説明するための図である。
携帯電話１では、全開した状態で携帯電話１の重心１５が送話部３に位置するように重量バランスが設定されている。
この設定のためには、携帯電話１が内蔵するバッテリの位置や電子装置の配置を考慮するほか、バランサなどの重りを付加してもよい。
このため、携帯電話１を全開状態で机上などに置くと、表示部６が起きあがり、ユーザは表示部６を見やすくなる。
また、図４（ｂ）の矢線で示したように、ユーザが送話部３の他端側を指などで押下すると、表示部６をより起きあがらせることができ、表示部６をより確認しやすくなる。 FIG. 4A is a view for explaining the position of the center of gravity of the mobile phone 1.
In the mobile phone 1, the weight balance is set so that the center of gravity 15 of the mobile phone 1 is positioned at the transmitter 3 in the fully opened state.
For this setting, a weight such as a balancer may be added in addition to considering the position of the battery built in the mobile phone 1 and the arrangement of the electronic device.
For this reason, when the mobile phone 1 is placed in a fully open state on a desk or the like, the display unit 6 is raised and the user can easily see the display unit 6.
4B, when the user presses the other end side of the transmission unit 3 with a finger or the like, the display unit 6 can be raised more and the display unit 6 It becomes easy to confirm.

このように、携帯電話１では、第１の構成部と第２の構成部のうちの何れか一方の構成部の内側面（携帯電話１では受話部２）には情報を表示する表示手段（表示部６）が設けられており、第１の構成部（受話部２）と第２の構成部（送話部３）を開いた場合に、他方の構成部（携帯電話１では送話部３）に重心が形成されている。
また、受話部２を第２の構成部とし、送話部３を第１の構成部とすることも可能である。 As described above, in the mobile phone 1, display means for displaying information on the inner surface (the receiving unit 2 in the mobile phone 1) of either one of the first component and the second component. When the first component (receiver 2) and the second component (transmitter 3) are opened, the other component (transmitter in the cellular phone 1) is provided. The center of gravity is formed in 3).
It is also possible for the receiver 2 to be the second component and the transmitter 3 to be the first component.

以上に説明した本実施の形態により次のような効果を得ることができる。
（１）開いた状態でも閉じた状態でも外周面が円柱面を有しているため、倒したり、落としたりした場合の対衝撃性が優れている。
即ち、従来の携帯電話の外側面は略平面で形成されているため、例えば、開いている状態でも閉じている状態でも机上に置くとき平らに置かなくてはならず、斜めに置いて手を離すと携帯電話に衝撃が加わる。
しかし、携帯電話１は、閉じるとシェル型形状となり、開くと半径Ｒの円柱面を構成するため、例えば、一部を設置して手を離しても回転して安定するため、衝撃が少ない。 The following effects can be obtained by the present embodiment described above.
(1) Since the outer peripheral surface has a cylindrical surface both in the open state and in the closed state, the impact resistance when it is tilted or dropped is excellent.
That is, since the outer surface of a conventional mobile phone is formed in a substantially flat surface, it must be placed flat when placed on a desk, for example, in an open state or a closed state. Release the phone and shock will be applied.
However, the cellular phone 1 has a shell shape when closed, and forms a cylindrical surface with a radius R when opened. For example, the cellular phone 1 rotates and stabilizes even when part of the cellular phone 1 is placed and released, so that there is little impact.

（２）携帯電話１を閉じた際の受話部２と送話部３の当接部分が、携帯電話１の先端部分からずれているため、蓋（受話部２）と本体（送話部３）の一部によって１つの曲面が形成され、携帯電話１をポケットなどに収納する場合でもポケットの縁に受話部２と送話部３の当接部分が引っかかりにくい。

（３）携帯電話１を開いた場合の重心が送話部３に位置するように設定されているため、携帯電話１を開いて机上に置いた場合でも携帯電話１は自重で起きあがり、表示部６が見やすくなる。また、送話部３の他端側を指で押下すると、携帯電話１がより起きあがる。
（４）携帯電話１が開状態であっても閉状態であっても、形状が手のひらにフィットするため、感触がよく、また、落としにくい。
（５）着信を振動で通知する場合、携帯電話１の外周面が円柱面であるため、携帯電話１が大きく運動し、ユーザにより効果的に通知を行うことができる。
（６）着信を音で通知する場合や音楽を流す場合、外周面の接地面が少ないため音による振動を減衰させることが少ない。更に外周面に設けられたスピーカなどの開口部により音を発するような構成の場合でも、机上に置いた際に開口部を塞ぐことがない。 (2) Since the contact portion of the receiver 2 and transmitter 3 when the mobile phone 1 is closed is displaced from the tip of the mobile phone 1, the lid (receiver 2) and the main body (transmitter 3) ) Form a single curved surface, and even when the mobile phone 1 is stored in a pocket or the like, the contact portion of the receiver 2 and transmitter 3 is not easily caught by the edge of the pocket.

(3) Since the center of gravity when the cellular phone 1 is opened is set to be located at the transmitter 3, the cellular phone 1 rises up with its own weight even when the cellular phone 1 is opened and placed on the desk, and the display unit 6 becomes easy to see. Further, when the other end side of the transmitter 3 is pressed with a finger, the mobile phone 1 is raised more.
(4) Whether the cellular phone 1 is in an open state or a closed state, the shape fits in the palm of the hand, so that the touch is good and it is difficult to drop.
(5) When the incoming call is notified by vibration, since the outer peripheral surface of the mobile phone 1 is a cylindrical surface, the mobile phone 1 moves greatly and can be notified effectively by the user.
(6) When an incoming call is notified by sound or when music is played, vibration due to sound is less likely to be attenuated because there are few contact surfaces on the outer peripheral surface. Furthermore, even in the case of a structure that emits sound through an opening such as a speaker provided on the outer peripheral surface, the opening is not blocked when placed on a desk.

以上、本実施の形態では、携帯電話１を例に説明したが、これは携帯端末の種類を限定するものではなく、例えば、トランシーバや小型ＧＰＳ装置など、他の携帯端末としてもよい。   As described above, in the present embodiment, the mobile phone 1 has been described as an example. However, this does not limit the type of the mobile terminal, and other mobile terminals such as a transceiver and a small GPS device may be used.
