For convenience of explanation, the mobile terminal considering the close contact is referred to as “mobile terminal 1 </ b> B” in order to distinguish it from the mobile terminal 1. Note that the mobile terminal 1 and the mobile terminal 1B have the same hardware configuration. That is, the portable terminal 1B includes two antennas 121 and 122. However, the following description will be given on the assumption that the antenna 122 has better performance than the antenna 121.
　携帯端末１Ｂは、掌の一部または親指の付け根が携帯端末１Ｂに密着しているか否かを、背面タッチセンサ１０９および側面タッチセンサ１１０ａ～１１０ｄにより検知される接触面積の大きさに基づき判断する。携帯端末１Ｂは、掌の一部または親指の付け根が携帯端末１Ｂの表面に密着していると判断した場合に、当該密着している領域が各アンテナの各給電点の近傍であるか否かを判断する。 The portable terminal 1B determines whether a part of the palm or the base of the thumb is in close contact with the portable terminal 1B based on the size of the contact area detected by the back touch sensor 109 and the side touch sensors 110a to 110d. . When the mobile terminal 1B determines that a part of the palm or the base of the thumb is in close contact with the surface of the mobile terminal 1B, whether or not the close contact area is in the vicinity of each feeding point of each antenna. Judging.
　図１３は、ユーザが携帯端末１Ｂを横向きに把持した状態を表した図である。図１３を参照して、状態Ａは、横向きの姿勢の携帯端末１の右端側（図１３の状態Ａの場合には操作キー１０５とは反対側）を、ユーザが右手で把持した状態を表した図である。状態Ｂは、横向きの姿勢の携帯端末１Ｂの左端側を、ユーザが左手で把持した状態を表した図である。 FIG. 13 is a diagram illustrating a state in which the user holds the mobile terminal 1B sideways. Referring to FIG. 13, state A represents a state in which the user grips the right end side of mobile terminal 1 in the landscape orientation (the side opposite to operation key 105 in the case of state A in FIG. 13) with the right hand. FIG. State B is a diagram showing a state in which the user grips the left end side of the mobile terminal 1B in the landscape orientation with the left hand.
　状態Ａにおいては、アンテナ１２１の給電点Ｐ１の近傍の携帯端末１の表面（主面，背面，および側面）が手で覆わることになるため、携帯端末１Ｂは、アンテナ１２２を用いて通信機器と無線通信を行なう。つまり、携帯端末１Ｂは、給電点の近傍の表面が手で覆われていないアンテナ１２１を選択する。より詳しくは、掌の一部または親指の付け部が密着している領域Ｓα１，Ｓα２が給電点Ｐ１の近傍であるため、携帯端末１Ｂは、給電点Ｐ１とは異なる給電点Ｐ２を有するアンテナ１２２を選択する。なお、領域Ｓα１は、主面側の領域であり、領域Ｓα２は背面側の領域である。 In the state A, the surface (main surface, back surface, and side surface) of the mobile terminal 1 in the vicinity of the feeding point P1 of the antenna 121 is covered with hands, so the mobile terminal 1B uses the antenna 122 to communicate with the communication device. And wireless communication. That is, the portable terminal 1B selects the antenna 121 whose surface near the feeding point is not covered with a hand. More specifically, since the regions Sα1 and Sα2 where a part of the palm or the thumb attachment part is in close contact are in the vicinity of the feeding point P1, the portable terminal 1B has an antenna 122 having a feeding point P2 different from the feeding point P1. Select. The region Sα1 is a region on the main surface side, and the region Sα2 is a region on the back side.
　状態Ａから状態Ｂに遷移すると、アンテナ１２２の給電点Ｐ２の近傍の表面が手で覆われることになるため、携帯端末１Ｂは、アンテナ１２１を用いて通信機器と無線通信を行なう。つまり、携帯端末１Ｂは、給電点の近傍の表面が手で覆われていないアンテナ１２１を選択する。より詳しくは、掌の一部および親指の付け部が密着している領域Ｓβ１，Ｓβ２が給電点Ｐ２の近傍であるため、携帯端末１Ｂは、給電点Ｐ２とは異なる給電点Ｐ１を有するアンテナ１２１を選択する。なお、領域Ｓβ１は、主面側の領域であり、領域Ｓβ２は背面側の領域である。 When the state A is changed to the state B, the surface of the antenna 122 in the vicinity of the feeding point P2 is covered with a hand, so that the mobile terminal 1B performs wireless communication with the communication device using the antenna 121. That is, the portable terminal 1B selects the antenna 121 whose surface near the feeding point is not covered with a hand. More specifically, since the regions Sβ1 and Sβ2 where a part of the palm and the thumb attachment part are in close contact are in the vicinity of the feeding point P2, the mobile terminal 1B has an antenna 121 having a feeding point P1 different from the feeding point P2. Select. Note that the region Sβ1 is a region on the main surface side, and the region Sβ2 is a region on the back surface side.
　図１４は、ユーザが携帯端末１Ｂを縦向きに把持した状態を表した図である。図１４を参照して、状態Ａは、縦向きの姿勢の携帯端末１の下端側（図１４の状態Ａの場合には操作キー１０５側）を、ユーザが右手で把持した状態を表した図である。状態Ｂは、縦向きの姿勢の携帯端末１Ｂの上端側を、ユーザが左手で把持した状態を表した図である。 FIG. 14 is a diagram illustrating a state in which the user holds the mobile terminal 1B in the vertical direction. Referring to FIG. 14, state A is a diagram showing a state in which the user grips the lower end side of portable terminal 1 in the vertical orientation (the operation key 105 side in the case of state A in FIG. 14) with the right hand. It is. State B is a diagram showing a state in which the user grips the upper end side of the portable terminal 1B in the portrait orientation with the left hand.
　状態Ａにおいて、領域Ｓγ１，Ｓγ２は、掌の一部または親指の付け部が密着している領域（携帯端末１Ｂの表面の一部領域）である。なお、領域Ｓγ１は、主面側の領域であり、領域Ｓγ２は背面側の領域である。状態Ａにおいては、アンテナ１２２の給電点Ｐ２の近傍の表面が手で覆われることになるため、携帯端末１Ｂは、アンテナ１２１を用いて通信機器と無線通信を行なう。つまり、携帯端末１Ｂは、給電点の近傍の表面が手で覆われていないアンテナ１２１を選択する。 In state A, regions Sγ1 and Sγ2 are regions (partial regions on the surface of the mobile terminal 1B) where a part of the palm or the thumb attachment is in close contact. The region Sγ1 is a region on the main surface side, and the region Sγ2 is a region on the back surface side. In the state A, since the surface of the antenna 122 in the vicinity of the feeding point P2 is covered with a hand, the mobile terminal 1B performs wireless communication with the communication device using the antenna 121. That is, the portable terminal 1B selects the antenna 121 whose surface near the feeding point is not covered with a hand.
　状態Ｂにおいて、領域Ｓδ１，Ｓδ２は、掌の一部または親指の付け部が密着している領域（携帯端末１Ｂの表面の一部領域）である。なお、領域Ｓδ１は、主面側の領域であり、領域Ｓδ２は背面側の領域である。状態Ａから状態Ｂに遷移すると、アンテナ１２２の左端側（給電点Ｐ２と反対側）の近傍の表面が手で覆われることになる。しかしながら、アンテナ１２１の給電点Ｐ１の近傍の表面とアンテナ１２２の給電点Ｐ２の近傍の表面とは手で覆われていない。また、上述したとおり、アンテナ１２２の方がアンテナ１２１よりも性能がよい。したがって、携帯端末１Ｂは、アンテナ１２２を用いて通信機器と無線通信を行なう。つまり、携帯端末１Ｂは、給電点の近傍の筐体表面が手で覆われていないアンテナ１２１，１２２のうち、性能の良いアンテナ１２２を選択する。より詳しくは、携帯端末１Ｂは、携帯端末１Ｂの表面と密着している領域が給電点の近傍にない場合には、親指の可動範囲を推定してアンテナを切り替える。 In state B, regions Sδ1 and Sδ2 are regions where a part of the palm or the thumb attachment part is in close contact (partial region on the surface of portable terminal 1B). The region Sδ1 is a region on the main surface side, and the region Sδ2 is a region on the back surface side. When the state A is changed to the state B, the surface of the antenna 122 near the left end side (the side opposite to the feeding point P2) is covered with a hand. However, the surface of the antenna 121 near the feeding point P1 and the surface of the antenna 122 near the feeding point P2 are not covered with hands. Further, as described above, the antenna 122 has better performance than the antenna 121. Therefore, the mobile terminal 1 </ b> B performs wireless communication with the communication device using the antenna 122. That is, the portable terminal 1B selects the antenna 122 with good performance among the antennas 121 and 122 whose casing surface near the feeding point is not covered with hands. More specifically, when the area that is in close contact with the surface of the portable terminal 1B is not in the vicinity of the feeding point, the portable terminal 1B estimates the movable range of the thumb and switches the antenna.
　以上のように、携帯端末１Ｂは、携帯端末１と同様、把持状態に基づいて、アンテナ１２１，１２２のうちから、通信機器との通信に用いる少なくとも１つのアンテナを選択する。具体的には、携帯端末１Ｂは、携帯端末１Ｂの姿勢（横向きまたは縦向きの姿勢）にかかわらず、２つのアンテナ１２１，１２２のうち給電点の近傍の表面が手で覆われていないアンテナを用いて、通信機器と通信する。 As described above, the mobile terminal 1 </ b> B selects at least one antenna used for communication with the communication device from the antennas 121 and 122 based on the gripping state, similarly to the mobile terminal 1. Specifically, the mobile terminal 1B uses an antenna whose surface in the vicinity of the feeding point is not covered with a hand, out of the two antennas 121 and 122, regardless of the attitude of the mobile terminal 1B (horizontal or vertical attitude). Use to communicate with communication equipment.
　図１５は、携帯端末１Ｂにおける処理の流れを説明するためのフローチャートである。以下では、図８に示したフローチャートと異なる点を主として説明する。図１５を参照して、携帯端末１Ｂ（正確には、ＣＰＵ１０１）は、ステップＳ４の後、ステップＳ５２において、掌の一部または親指の付け根が携帯端末１Ｂの表面と密着しているか否かを判断する。 FIG. 15 is a flowchart for explaining the flow of processing in the mobile terminal 1B. In the following, differences from the flowchart shown in FIG. 8 will be mainly described. Referring to FIG. 15, after step S4, portable terminal 1B (exactly CPU 101) determines in step S52 whether a part of the palm or the base of the thumb is in close contact with the surface of portable terminal 1B. to decide.
　携帯端末１Ｂは、密着していないと判断した場合（ステップＳ５２においてＮＯ）、処理をステップＳ８に進める。携帯端末１Ｂは、密着していると判断した場合（ステップＳ５２においてＹＥＳ）、ステップＳ５４において、当該密着している領域がアンテナの給電点の近傍であるか否かを判断する。 If it is determined that the portable terminal 1B is not in close contact (NO in step S52), the process proceeds to step S8. When it is determined that the portable terminal 1B is in close contact (YES in step S52), in step S54, it is determined whether or not the close contact region is in the vicinity of the feeding point of the antenna.
　携帯端末１Ｂは、給電点の近傍であると判断した場合（ステップＳ５４においてＹＥＳ）、処理をステップＳ８に進める。携帯端末１Ｂは、給電点の近傍でないと判断した場合（ステップＳ５４においてＮＯ）、処理をステップＳ６に進める。 If portable terminal 1B determines that the power supply point is in the vicinity of the feeding point (YES in step S54), the process proceeds to step S8. If portable terminal 1B determines that it is not in the vicinity of the feeding point (NO in step S54), the process proceeds to step S6.
　（ｈ４．ＭＩＭＯ）
　上記においては、複数のアンテナのうちから１つのアンテナを選択する構成を例に挙げて説明したが、これに限定されるものではない。 (H4. MIMO)
In the above description, the configuration in which one antenna is selected from a plurality of antennas has been described as an example. However, the present invention is not limited to this.
　たとえば、上記のアンテナの選択処理を、ＭＩＭＯ(multiple-input　and　multiple-output)をサポートするスマートフォン等の電子機器にも適用できる。つまり、複数のアンテナのうちから２つ以上のアンテナを組み合わせることによりデータ送受信に利用する帯域幅を広げて無線通信に対して、上記のアンテナの選択処理を適用できる。なお、この場合、選択部は、複数のアンテナのうちから、通信機器との通信に用いる少なくとも２つ以上のアンテナを選択することになる。 For example, the above antenna selection process can be applied to an electronic device such as a smartphone that supports MIMO (multiple-input and multiple-output). That is, by combining two or more antennas from among a plurality of antennas, the bandwidth used for data transmission / reception can be expanded to apply the above antenna selection process to wireless communication. In this case, the selection unit selects at least two or more antennas used for communication with the communication device from the plurality of antennas.
　（ｈ５．親指以外の可動領域）
　上記においては、可動領域推定部２２０が親指の可動領域のみを推定する構成を例に挙げて説明したが、これに限定されるものではない。可動領域推定部２２０が、各センサからの座標情報、姿勢情報等に基づいて、人差指、中指、薬指、および小指の可動領域を推定してもよい。この場合には、親指の可動領域と、親指以外の指の可動領域とを考慮して、アンテナを選択するように、選択部２３１を構成してもよい。なお、親指以外の指の可動領域を求める一例として、これらの指は、親指のようには自由に移動できないので、例えば、現在の指位置から所定の平行移動可能距離を設定して、その距離離れた位置までを可動領域としてもよい。 (H5. Movable region other than thumb)
In the above description, the configuration in which the movable region estimation unit 220 estimates only the movable region of the thumb has been described as an example. However, the present invention is not limited to this. The movable area estimation unit 220 may estimate the movable areas of the index finger, the middle finger, the ring finger, and the little finger based on coordinate information, posture information, and the like from each sensor. In this case, the selection unit 231 may be configured to select an antenna in consideration of the movable region of the thumb and the movable region of fingers other than the thumb. As an example of obtaining the movable region of fingers other than the thumb, since these fingers cannot move freely like the thumb, for example, a predetermined parallel movable distance is set from the current finger position, and the distance is set. It is good also as a movable area | region to the distant position.

FIG. 16D is a cross-sectional view taken along the line II-II in FIG.
　図１６（Ａ），（Ｂ），（Ｃ）を参照して、携帯端末１Ｃは、主面に、タッチスクリーン１０８と、操作キー１０５とを備えている。また、携帯端末１Ｃは、背面に、カメラ１０７を備えている。また、携帯端末１Ｃは、筐体の周辺部（２つの側面部）に、グリップセンサ１９１～１９４を備えている。詳しくは、携帯端末１Ｃの４つの側面部のうち、互いに対向する２つ側面部の各々に、２つのグリップセンサが配置されている。なお、２つの側面部は、携帯端末１Ｃの長手方向の側面部である。 Referring to FIGS. 16A, 16B, and 16C, mobile terminal 1C includes touch screen 108 and operation keys 105 on the main surface. The portable terminal 1C includes a camera 107 on the back surface. Further, the mobile terminal 1C includes grip sensors 191 to 194 on the periphery (two side portions) of the housing. Specifically, two grip sensors are disposed on each of two side surfaces facing each other among the four side surfaces of the mobile terminal 1C. The two side surfaces are side surfaces in the longitudinal direction of the mobile terminal 1C.
　各グリップセンサ１９１～１９４は、力が加わると、予め定められた信号を発生する。当該信号は、ＣＰＵ１０１に送られる。ユーザが携帯端末１Ｃを右手で把持した場合、たとえば、１つのグリップセンサ１９１に指が掛っていると、４つのグリップセンサ１９１～１９４のうち１つのグリップセンサ１９１だけが上記信号を発生する。 Each grip sensor 191 to 194 generates a predetermined signal when a force is applied. The signal is sent to the CPU 101. When the user grips the portable terminal 1C with the right hand, for example, when one finger is placed on one grip sensor 191, only one grip sensor 191 among the four grip sensors 191 to 194 generates the signal.
　図１６（Ｄ）を参照して、携帯端末１Ｃは、携帯端末１と同様、筐体１０内に、複数のアンテナ１２１，１２２と、複数の電子回路１３１～１３４とを備える。 Referring to FIG. 16D, the portable terminal 1C includes a plurality of antennas 121 and 122 and a plurality of electronic circuits 131 to 134 in the housing 10 as in the portable terminal 1.
　携帯端末１Ｃは、携帯端末１と同様、アンテナ１２１およびアンテナ１２２から１つのアンテナを選択し、図示しない通信機器（他の通信端末、基地局等）との間で無線通信を行なう。つまり、携帯端末１Ｃは、無線通信に利用するアンテナをアンテナ１２１とアンテナ１２２との間で切り替える。アンテナの具体的な選択の手法については、後述する。 Similarly to the portable terminal 1, the portable terminal 1C selects one antenna from the antenna 121 and the antenna 122, and performs wireless communication with a communication device (other communication terminal, base station, etc.) not shown. That is, 1 C of portable terminals switch the antenna utilized for radio | wireless communication between the antenna 121 and the antenna 122. FIG. A specific antenna selection method will be described later.
　また、携帯端末１Ｃは、携帯端末１と同様、携帯端末１Ｃの姿勢が横向きの姿勢から縦向きの姿勢に変化、または当該姿勢が縦向きの姿勢から横向きの姿勢に変化した場合、ディスプレイの表示画面を９０度回転させる画面回転機能を有する。 Similarly to the portable terminal 1, the portable terminal 1C displays the display when the posture of the portable terminal 1C changes from the horizontal posture to the vertical posture, or when the posture changes from the vertical posture to the horizontal posture. It has a screen rotation function that rotates the screen by 90 degrees.
　携帯端末１Ｃは、携帯端末１と同様のハードウェア構成を有する。だたし、以下では、アンテナ１２２の方がアンテナ１２１よりも性能が良いものとして説明する。 The mobile terminal 1 </ b> C has the same hardware configuration as the mobile terminal 1. However, in the following description, it is assumed that the antenna 122 has better performance than the antenna 121.
　図１７は、ユーザが携帯端末１Ｃを横向きに把持した状態を表した図である。図１７を参照して、状態Ａは、横向きの姿勢の携帯端末１Ｃの右端側（図１７の状態Ａの場合には操作キー１０５とは反対側）を、ユーザが右手で把持した状態を表した図である。状態Ｂは、横向きの姿勢の携帯端末１Ｃの左端側を、ユーザが左手で把持した状態を表した図である。 FIG. 17 is a diagram illustrating a state where the user holds the mobile terminal 1C sideways. Referring to FIG. 17, state A represents a state in which the user grips the right end side of portable terminal 1 </ b> C in the landscape orientation (the side opposite to operation key 105 in the case of state A in FIG. 17) with the right hand. FIG. State B is a diagram showing a state in which the user grips the left end side of the mobile terminal 1C in the landscape orientation with the left hand.
　状態Ａにおいては、グリップセンサ１９３に手（詳しくは親指の付け根）が接触する。他のグリップセンサ１９１，１９２，１９４には手は接触しない。したがって、グリップセンサ１９３のみが信号を発生し、残りの３つのグリップセンサ１９１，１９２，１９４は信号を発生しない。 In state A, the hand (specifically, the base of the thumb) contacts the grip sensor 193. The other grip sensors 191, 192, 194 are not touched by the hand. Therefore, only the grip sensor 193 generates a signal, and the remaining three grip sensors 191, 192, 194 do not generate a signal.
　この場合、携帯端末１Ｃが横位置であるため、アンテナ１２１の給電点Ｐ１の近傍の携帯端末１Ｃの表面（主面，背面，および側面）が手で覆われている可能性がある。また、携帯端末１Ｃが横位置であり、かつグリップセンサ１９３のみが信号を発生していることから、携帯端末１Ｃは、ユーザが右手で携帯端末１Ｃを把持していると判断できる。このため、携帯端末１Ｃは、アンテナ１２２を用いて通信機器と無線通信を行なう。つまり、携帯端末１Ｃは、給電点の近傍の表面が手で覆われていないと判断し得るアンテナ１２２を選択する。換言すれば、携帯端末１Ｃは、アンテナ１２１，１２２のうち、グリップセンサ１９３から遠い方に位置するアンテナ１２２を選択する。 In this case, since the mobile terminal 1C is in the horizontal position, the surface (main surface, back surface, and side surface) of the mobile terminal 1C in the vicinity of the feeding point P1 of the antenna 121 may be covered with a hand. Further, since the portable terminal 1C is in the horizontal position and only the grip sensor 193 generates a signal, the portable terminal 1C can determine that the user is holding the portable terminal 1C with the right hand. For this reason, the mobile terminal 1 </ b> C performs wireless communication with the communication device using the antenna 122. That is, 1 C of portable terminals select the antenna 122 which can judge that the surface of the vicinity of a feeding point is not covered with the hand. In other words, the mobile terminal 1 </ b> C selects the antenna 122 located farther from the grip sensor 193 among the antennas 121 and 122.
　状態Ａから状態Ｂに遷移すると、グリップセンサ１９４に手（詳しくは親指の付け根）が接触する。他のグリップセンサ１９１，１９２，１９３には手は接触しない。したがって、グリップセンサ１９４のみが信号を発生し、残りの３つのグリップセンサ１９１，１９２，１９３は信号を発生しない。 When transitioning from state A to state B, the hand (in detail, the base of the thumb) contacts the grip sensor 194. The other grip sensors 191, 192 and 193 do not touch the hand. Therefore, only the grip sensor 194 generates a signal, and the remaining three grip sensors 191, 192, 193 do not generate a signal.
　この場合、携帯端末１Ｃが横位置であるため、アンテナ１２２の給電点Ｐ２の近傍の携帯端末１Ｃの表面（主面，背面，および側面）が手で覆われている可能性がある。また、携帯端末１Ｃが横位置であり、かつグリップセンサ１９４のみが信号を発生していることから、携帯端末１Ｃは、ユーザが左手で携帯端末１Ｃを把持していると判断できる。このため、携帯端末１Ｃは、アンテナ１２１を用いて通信機器と無線通信を行なう。つまり、携帯端末１Ｃは、給電点の近傍の表面が手で覆われていないと判断し得るアンテナ１２１を選択する。換言すれば、携帯端末１Ｃは、アンテナ１２１，１２２のうち、グリップセンサ１９４から遠い方に位置するアンテナ１２１を選択する。 In this case, since the mobile terminal 1C is in the horizontal position, the surface (main surface, back surface, and side surface) of the mobile terminal 1C in the vicinity of the feeding point P2 of the antenna 122 may be covered with hands. Further, since the mobile terminal 1C is in the horizontal position and only the grip sensor 194 generates a signal, the mobile terminal 1C can determine that the user is holding the mobile terminal 1C with the left hand. For this reason, the mobile terminal 1 </ b> C performs wireless communication with the communication device using the antenna 121. That is, 1 C of portable terminals select the antenna 121 which can be judged that the surface of the vicinity of a feeding point is not covered with the hand. In other words, the mobile terminal 1 </ b> C selects the antenna 121 located farther from the grip sensor 194 among the antennas 121 and 122.

State B is a diagram showing a state in which the user holds the left end side of the portable terminal 1C in the vertical orientation with the left hand.
　状態Ａにおいては、グリップセンサ１９４に手（詳しくは親指の付け根）が接触する。他のグリップセンサ１９１，１９２，１９３には手は接触しない。したがって、グリップセンサ１９４のみが信号を発生し、残りの３つのグリップセンサ１９１，１９２，１９３は信号を発生しない。 In state A, the hand (specifically, the base of the thumb) contacts the grip sensor 194. The other grip sensors 191, 192 and 193 do not touch the hand. Therefore, only the grip sensor 194 generates a signal, and the remaining three grip sensors 191, 192, 193 do not generate a signal.
　この場合、携帯端末１Ｃが縦位置であるため、アンテナ１２２の給電点Ｐ２の近傍の携帯端末１Ｃの表面（主面，背面，および側面）が手で覆われている可能性がある。また、携帯端末１Ｃが縦位置であり、かつグリップセンサ１９４のみが信号を発生していることから、携帯端末１Ｃは、ユーザが右手で携帯端末１Ｃを把持していると判断できる。このため、携帯端末１Ｃは、アンテナ１２１を用いて通信機器と無線通信を行なう。つまり、携帯端末１Ｃは、給電点の近傍の表面が手で覆われていないと判断し得るアンテナ１２１を選択する。換言すれば、携帯端末１Ｃは、アンテナ１２１，１２２のうち、グリップセンサ１９４から遠い方に位置するアンテナ１２１を選択する。 In this case, since the mobile terminal 1C is in the vertical position, the surface (main surface, back surface, and side surface) of the mobile terminal 1C in the vicinity of the feeding point P2 of the antenna 122 may be covered with hands. Further, since the mobile terminal 1C is in the vertical position and only the grip sensor 194 generates a signal, the mobile terminal 1C can determine that the user is holding the mobile terminal 1C with the right hand. For this reason, the mobile terminal 1 </ b> C performs wireless communication with the communication device using the antenna 121. That is, 1 C of portable terminals select the antenna 121 which can be judged that the surface of the vicinity of a feeding point is not covered with the hand. In other words, the mobile terminal 1 </ b> C selects the antenna 121 located farther from the grip sensor 194 among the antennas 121 and 122.
　状態Ａから状態Ｂに遷移すると、グリップセンサ１９２に手（詳しくは親指の付け根）が接触する。他のグリップセンサ１９１，１９３，１９４には手は接触しない。したがって、グリップセンサ１９２のみが信号を発生し、残りの３つのグリップセンサ１９１，１９３，１９４は信号を発生しない。 When the state A changes to the state B, the hand (specifically, the base of the thumb) contacts the grip sensor 192. The other grip sensors 191, 193, 194 are not touched by the hand. Therefore, only the grip sensor 192 generates a signal, and the remaining three grip sensors 191, 193, 194 do not generate a signal.
　この場合、携帯端末１Ｃが縦位置であり、かつグリップセンサ１９２のみが信号を発生していることから、携帯端末１Ｃは、ユーザが左手で携帯端末１Ｃを把持していると判断できる。また、携帯端末１Ｃが縦位置であるため、携帯端末１Ｃは、アンテナ１２１の給電点Ｐ１の近傍の表面とアンテナ１２２の給電点Ｐ２の近傍の表面とは手で覆われていないと判断できる。さらに、上述したとおり、アンテナ１２２の方がアンテナ１２１よりも性能がよい。 In this case, since the portable terminal 1C is in the vertical position and only the grip sensor 192 generates a signal, the portable terminal 1C can determine that the user is holding the portable terminal 1C with the left hand. Further, since the portable terminal 1C is in the vertical position, the portable terminal 1C can determine that the surface of the antenna 121 near the feeding point P1 and the surface of the antenna 122 near the feeding point P2 are not covered with hands. Furthermore, as described above, the performance of the antenna 122 is better than that of the antenna 121.
　このため、携帯端末１Ｃは、アンテナ１２２を用いて通信機器と無線通信を行なう。つまり、携帯端末１Ｃは、給電点の近傍の表面が手で覆われていないと判断し得るアンテナ１２１，１２２のうちから、アンテナ性能の良いアンテナ１２２を選択する。 For this reason, the mobile terminal 1 </ b> C performs wireless communication with the communication device using the antenna 122. That is, 1 C of portable terminals select the antenna 122 with good antenna performance from the antennas 121 and 122 which can be judged that the surface in the vicinity of the feeding point is not covered with the hand.
　以上のように、携帯端末１Ｃは、把持状態に基づいて、アンテナ１２１，１２２のうちから、通信機器との通信に用いる少なくとも１つのアンテナを選択する。具体的には、携帯端末１Ｃは、携帯端末１と同様、携帯端末１Ｃの姿勢（横向きまたは縦向きの姿勢）にかかわらず、２つのアンテナ１２１，１２２のうち給電点の近傍の表面が手で覆われていないアンテナを用いて、通信機器と通信する。 As described above, the mobile terminal 1C selects at least one antenna used for communication with the communication device from the antennas 121 and 122 based on the gripping state. Specifically, in the same manner as the mobile terminal 1, the mobile terminal 1 </ b> C has a surface near the feeding point of the two antennas 121 and 122, regardless of the orientation of the mobile terminal 1 </ b> C (lateral orientation or vertical orientation). Communicate with a communication device using an uncovered antenna.
　これにより、携帯端末１Ｃは、通信性能（通信品質）のよい方のアンテナを用いて、通信機器と通信することが可能となる。 Thereby, the mobile terminal 1C can communicate with the communication device using the antenna having the better communication performance (communication quality).
