Although not shown, various circuits for realizing the function of the mobile phone are mounted on the printed circuit board provided in the upper case 2. Although the upper case 2 is made of resin in the present embodiment, the present invention is not limited to this.
　下筐体３は、送話部（マイクロフォン）１３と、操作部１４などを収容している。なお、図示しないが、下筐体３内に設けられたプリント基板には、携帯電話の機能を実現する回路が実装されている。下筐体３の主面３Ａには、携帯電話機１が第１、第２開状態のときに露出する操作部１４が設けられる。なお、本実施の形態では、下筐体３は、上筐体２と同様、樹脂製であるが、これに限らない。 The lower housing 3 accommodates a transmitter (microphone) 13, an operation unit 14 and the like. Although not shown, a circuit for realizing the function of the mobile phone is mounted on the printed circuit board provided in the lower housing 3. The main surface 3A of the lower housing 3 is provided with an operation unit 14 which is exposed when the mobile phone 1 is in the first and second open states. In the present embodiment, the lower case 3 is made of resin as in the upper case 2, but the invention is not limited to this.
　マイクロフォン１３は、下筐体３の主面３Ａにあって携帯電話機１が閉状態のときに上筐体２が対向して覆われ、携帯電話機１が第１開状態又は第２開状態のときに露出するように設けられている。通話時は、使用者の音声を通信相手に送話する。 When the microphone 13 is on the main surface 3A of the lower housing 3 and the mobile telephone 1 is in the closed state, the upper housing 2 is opposed and covered, and when the mobile telephone 1 is in the first open state or the second open state It is provided to be exposed to During a call, the user's voice is sent to the other party.
　操作部１４は、下筐体３の主面３Ａに配置されている。電話番号や文字を入力するために、数字や文字、記号が印刷されている。受話や終話、レシーバ５などから出力される音量の調節、マナーモードへの切替え、メニュー画面における選択と確定などができる複数の操作ボタンなどからなる。 The operation unit 14 is disposed on the main surface 3A of the lower housing 3. Numbers, letters and symbols are printed to enter phone numbers and letters. It consists of a plurality of operation buttons that can be used to receive and end calls, adjust the volume output from the receiver 5, etc., switch to the manner mode, and select and confirm on the menu screen.
　連結部４は、第１連結部（第１ヒンジ）２８と第２連結部（第２ヒンジ）２９とが装着され、上筐体２と下筐体３とを回動可能に連結するものである。また、連結部４には、図示しないが、上筐体２のプリント基板と、下筐体３の第２プリント基板とを電気的に接続する、配線部材（ケーブル）が通される。 The connecting portion 4 is mounted with a first connecting portion (first hinge) 28 and a second connecting portion (second hinge) 29 and rotatably connects the upper case 2 and the lower case 3. is there. Further, though not illustrated, a wiring member (cable), which is not illustrated, electrically connects the printed circuit board of the upper housing 2 and the second printed circuit board of the lower housing 3.
　図２を参照して、開閉検出用磁石７０と磁気検出素子８０とについて説明する。図２は、携帯電話機１の第２開状態における部分拡大図である。図２に示すように、連結部４の一部は、操作部１４が設けられた下筐体３の主面３Ａから、筐体厚み方向に突出する凸部７２を形成する。そして、連結部４の凸部内には、開閉検出用磁石７０が設けられている。詳細は、後述するが、連結部４の凸部７２の一部は、傾斜部４２を形成する。開閉検出用磁石７０は、筐体短手方向（図中、Ｙ軸方向）において、中央付近に位置している。 The open / close detection magnet 70 and the magnetic detection element 80 will be described with reference to FIG. FIG. 2 is a partially enlarged view of the mobile phone 1 in the second open state. As shown in FIG. 2, a part of the connecting portion 4 forms a convex portion 72 which protrudes in the housing thickness direction from the main surface 3A of the lower housing 3 provided with the operation portion 14. And in the convex part of the connection part 4, the magnet 70 for open / close detection is provided. Although the details will be described later, a part of the convex portion 72 of the connecting portion 4 forms the inclined portion 42. The open / close detection magnet 70 is located near the center in the short side direction of the housing (in the Y-axis direction in the drawing).
　一方、図２に示すように、第１表示部７が設けられた上筐体２の主面２Ａの連結部４寄り端部には、上筐体２の主面２Ａを基準として、突出する連結部４の一部（凸部７２）の突出形状に沿って凹み形状を有する凹部７１が形成されている。詳細は後述するが、携帯電話機１が閉じ状態（図１（ａ）参照）において、凸部７２は凹部７１に係合して、上筐体２と下筐体３のガタつきを小さく抑える。また、凹部７１の内側には、突起７３Ａ、突起７３Ｂ、突起７４が突出して形成されており、凸部７２と凹部７１が係合したときのガタつきをさらに小さく抑える。突起７３Ａ、突起７３Ｂ、突起７４は、筐体よりも低硬度の材料（軟らかい材料）で構成することにより、係合時に凸部７２の表面を傷つけたり、塗装の剥がれを防ぐ。 On the other hand, as shown in FIG. 2, the end of the main surface 2A of the upper housing 2 provided with the first display portion 7 is projected toward the connecting portion 4 with reference to the main surface 2A of the upper housing 2 A recessed portion 71 having a recessed shape is formed along the protruding shape of a part (convex portion 72) of the connecting portion 4. Although the details will be described later, in the closed state of the mobile phone 1 (see FIG. 1A), the convex portion 72 engages with the concave portion 71 to reduce the rattling of the upper case 2 and the lower case 3 small. Further, a projection 73A, a projection 73B, and a projection 74 are formed on the inner side of the recess 71 so as to further suppress rattling when the protrusion 72 and the recess 71 are engaged. The projections 73A, the projections 73B, and the projections 74 are made of a material (softer material) having a hardness lower than that of the housing, so that the surfaces of the projections 72 are damaged during engagement, and the coating is prevented from peeling off.
　上筐体２の凹部７１の裏面には、磁気検出素子８０が設けられている。磁気検出素子８０は、携帯電話機１が閉状態（図１（ａ）参照）の時、開閉検出用磁石７０の上方に位置し、開閉検出用磁石７０と筐体厚み方向において重なる位置で、凹部７１に設けられている。磁気検出素子８０は、携帯電話機１が閉状態（図１（ａ）参照）の時、開閉検出用磁石７０に対向する位置、言い換えると、筐体短手方向（図中、Ｙ軸方向）において、中央付近に位置する。 A magnetic detection element 80 is provided on the back surface of the recess 71 of the upper housing 2. The magnetic detection element 80 is located above the open / close detection magnet 70 when the cellular phone 1 is in the closed state (see FIG. 1A), and is a recess at a position overlapping the open / close detection magnet 70 in the housing thickness direction. 71 is provided. When the mobile telephone 1 is in the closed state (see FIG. 1A), the magnetic detection element 80 is at a position facing the open / close detection magnet 70, in other words, in the short side direction of the housing (Y axis direction in the figure). , Located near the center.
　磁気検出素子８０は、開閉検出用磁石７０の磁気変化を検出することで、ユーザーが下筐体３に対して上筐体２を矢印Ｂ方向に開く際の横開き角度θ１が所定範囲にある場合に、携帯電話機１の横開き状態を検出する。磁気検出素子８０は、上筐体２内に設けられたプリント基板に電気的に接続される。磁気検出素子８０が携帯電話機１の横開き状態を検出すると、プリント基板に信号を送信し、携帯電話機１は、たとえば、第１表示部７を動作させる。 The magnetic detection element 80 detects a magnetic change of the open / close detection magnet 70, whereby the lateral opening angle θ1 when the user opens the upper housing 2 with respect to the lower housing 3 in the direction of arrow B is within a predetermined range. In this case, the side open state of the mobile phone 1 is detected. The magnetic detection element 80 is electrically connected to a printed circuit board provided in the upper housing 2. When the magnetic detection element 80 detects the side-to-side open state of the mobile phone 1, it transmits a signal to the printed circuit board, and the mobile phone 1 operates the first display unit 7, for example.
　上述のように、本実施形態によれば、開閉検出用磁石７０と磁気検出素子８０をそれぞれ筐体短手方向（図中、Ｙ軸方向）において、中央付近に配置する構成により、ユーザーが下筐体３に対して上筐体２を矢印Ｂ方向に開く際に、磁気検出素子８０は、携帯電話機１の横開き角度θ１が大きすぎず、かつ、小さすぎない（誤検出しない）、所定範囲の角度内で携帯電話機１の横開き状態を検出する。すなわち、ユーザーから表示部が見える角度より小さい角度で、携帯電話機１の横開き状態を検出し、横向きの画面表示を行う。なお、開閉検出用磁石７０と磁気検出素子８０とは、磁気検出素子８０の性能によっては、必ず中央付近に位置する必要は無く、ユーザーから表示部全体が見える角度より小さい角度で、横向き状態を検出できる位置であればよい。 As described above, according to the present embodiment, the user can lower the open / close detection magnet 70 and the magnetic detection element 80 by arranging the magnet 70 and the magnetic detection element 80 in the vicinity of the center in the housing short direction (Y axis direction in the figure). When the upper case 2 is opened in the direction of arrow B relative to the case 3, the magnetic detection element 80 does not have too large or small lateral opening angle θ 1 of the mobile telephone 1 (not erroneously detected), predetermined The side open state of the mobile phone 1 is detected within the range angle. That is, the side-to-side open state of the mobile phone 1 is detected at an angle smaller than the angle at which the display section can be seen by the user, and the screen display sideways is performed. The open / close detection magnet 70 and the magnetic detection element 80 do not necessarily have to be positioned near the center depending on the performance of the magnetic detection element 80, and the horizontal state is at an angle smaller than the angle at which the entire display unit can be viewed by the user. It may be any position that can be detected.
　本実施の形態では、図３に示すように、携帯電話機１が閉状態（図１（ａ）参照）のとき、開閉検出用磁石７０が内部に設けられた凸部７２は、磁気検出素子８０が裏面に設けられている上筐体２の凹部７１と係合する。そのため、例えば、図３の矢印で示す力Ｆが上筐体２に加えられても、筐体短手方向（図中、Ｙ軸方向）において、下筐体３に対する上筐体２（図中、破線）のずれを表す角度θ２は、ほぼゼロとなる。したがって、携帯電話機１が閉じ状態（図１（ａ）参照）のとき、凸部７２が凹部７１に係合することで、上筐体２及び下筐体３のガタつきを小さく抑えることができる。このとき、凹部７１の内側から突出して設けられる突起７３Ａ、突起７３Ｂにより、凸部７２の表面を傷つけることなく、さらにθ２のガタつきを小さく押さえることができる。なお、突起７３Ａ、突起７３Ｂ、突起７４は、図２に示すように、いずれも上筐体２の短手方向における中央よりも第２回動軸と反対側配置すると、係合時のθ２の方向のガタつきを効果的に抑えることができる。 In the present embodiment, as shown in FIG. 3, when the cellular phone 1 is in the closed state (see FIG. 1A), the convex portion 72 provided with the open / close detection magnet 70 is a magnetic detection element 80. Engages with the recess 71 of the upper case 2 provided on the back surface. Therefore, for example, even if force F shown by the arrow in FIG. 3 is applied to the upper case 2, the upper case 2 (in the figure, with respect to the lower case 3) in the short direction of the case (in the Y axis direction in the figure). The angle θ2 representing the deviation of the broken line) is almost zero. Therefore, when the mobile phone 1 is in the closed state (see FIG. 1A), the protrusion 72 engages with the recess 71, whereby rattling of the upper case 2 and the lower case 3 can be suppressed to a small level. . At this time, the protrusion 73A and the protrusion 73B provided so as to protrude from the inside of the recess 71 can further suppress the play of θ2 to a small size without damaging the surface of the protrusion 72. In addition, as shown in FIG. 2, when all of the projections 73A, 73B, and 74 are disposed on the opposite side of the second rotation axis than the center in the short side direction of the upper housing 2, θ2 at the time of engagement is It is possible to effectively suppress the rattling of the direction.
　図４は、図１に示すIV－IV線の断面図である。図４中の参照符号Ｆは、図３に示す力Ｆを示す。また、図４に示す参照符号Ｍは、磁気検出素子８０の中心位置と開閉検出用磁石７０の中心位置とを結ぶ直線を示す。図４の直線Ｍで示すように、携帯電話機１が閉状態（図１（ａ）参照）のとき、図４の矢印で示す力Ｆが上筐体２に加えられても、磁気検出素子８０の中心位置と開閉検出用磁石７０の中心位置とは、筐体厚み方向（図中、Ｚ軸方向）において、ほぼ一致している。そのため、携帯電話機１は、外部から力Ｆが携帯電話機１に加わっても上筐体２及び下筐体３のガタつきを小さく抑えることができるので、開閉検出用磁石７０と磁気検出素子８０の位置ずれが起こりにくい。この構成によれば、上筐体２及び下筐体３のわずかなガタつきにより、磁気検出素子８０が開閉検出用磁石７０の磁力に反応しなくなり、携帯電話機１が閉じ状態にもかかわらず、磁気検出素子８０で「横開き状態」と誤検出して横画面表示してしまう、という事態も防止することができる。すなわち、誤検出を防ぎ、適切な角度で検出するよう構成することで、無駄な消費電力を削減することができる。
　なお、力Ｆが加えられる方向は、図３に示す方向に限らず、任意の方向から加えられても、力Ｆが図３に示す方向から加えられた場合と同様、携帯電話機１は、磁気検出素子８０が携帯電話機１の横開き状態を検出する際に、誤検出しにくい。 FIG. 4 is a cross-sectional view taken along line IV-IV shown in FIG. The reference symbol F in FIG. 4 indicates the force F shown in FIG. Further, reference symbol M shown in FIG. 4 indicates a straight line connecting the center position of the magnetic detection element 80 and the center position of the open / close detection magnet 70. As shown by the straight line M in FIG. 4, when the cellular phone 1 is in the closed state (see FIG. 1 (a)), even if the force F shown by the arrow in FIG. The central position of the sensor and the central position of the open / close detection magnet 70 substantially coincide with each other in the housing thickness direction (the Z-axis direction in the drawing). Therefore, even if force F is applied to the mobile phone 1 from the outside, rattling of the upper case 2 and the lower case 3 can be suppressed to a small degree, so that the open / close detection magnet 70 and the magnetic detection element 80 Misalignment is unlikely to occur. According to this configuration, the magnetic detection element 80 does not respond to the magnetic force of the open / close detection magnet 70 due to slight rattling of the upper case 2 and the lower case 3, and the mobile phone 1 is closed even though It is also possible to prevent a situation in which the magnetic detection element 80 erroneously detects "sideways open state" and displays on the horizontal screen. That is, by preventing false detection and performing detection at an appropriate angle, wasteful power consumption can be reduced.
The direction in which the force F is applied is not limited to the direction shown in FIG. 3, and the mobile phone 1 is magnetic as in the case where the force F is applied from the direction shown in FIG. When the detection element 80 detects the side-to-side open state of the mobile phone 1, erroneous detection is difficult.
　次に、図２～図６を参照して、連結部４の構成について説明する。図５に示す連結部４は、連結部本体４０と、連結部カバー４１とから構成される。 Next, the configuration of the connecting portion 4 will be described with reference to FIGS. The connecting portion 4 shown in FIG. 5 is composed of a connecting portion main body 40 and a connecting portion cover 41.
　図５に示す連結部本体４０は、筐体厚み方向（図中、Ｚ軸方向）において、連結部カバー４１の傾斜面４１Ａと滑らかに連続する傾斜面４２Ａを有する傾斜部４２と、第２ヒンジ２９を収容するヒンジ収容部４３と、傾斜部４２の下側に位置する収容部４４とを備える。 The connecting portion main body 40 shown in FIG. 5 has an inclined portion 42 having an inclined surface 42A smoothly continuous with the inclined surface 41A of the connecting portion cover 41 in the housing thickness direction (the Z axis direction in the drawing), and a second hinge. A hinge accommodation portion 43 for accommodating 29 and an accommodation portion 44 located below the inclined portion 42.
　図５に示す連結部カバー４１は、筐体短手方向（図５中、Ｙ軸方向）に沿って、傾斜部４２と滑らかに連続する傾斜面４１Ａと、傾斜面４１Ａと連続し、回動軸部材５０の径部５１の形状に沿って径部５１を上方から覆う曲面４１Ｂと、を備える。回動軸部材５０の構成ついては、後述する。 The connecting portion cover 41 shown in FIG. 5 is continuous with the inclined surface 41A and the inclined surface 41A which are smoothly continuous with the inclined portion 42 along the short side direction of the housing (Y axis direction in FIG. 5). And a curved surface 41B covering the diameter portion 51 from above along the shape of the diameter portion 51 of the shaft member 50. The configuration of the pivot shaft member 50 will be described later.
　図２に示すように、傾斜部４２は、筐体短手方向（図中、Ｙ軸方向）に沿って、傾斜面４１Ａと滑らかに連続する傾斜面４２Ａを有する。そのため、連結部４の外観品位を損なわない。また、図２に示すように、傾斜部４２は、携帯電話機１が横開き状態の場合、操作部１４が設けられている下筐体３の主面３Ａから、筐体厚み方向（図中Ｚ軸方向）において突出する。つまり、傾斜部４２は、連結部４の凸部７２の一部を形成する。なお、本実施形態では、凸部７２を傾斜部４２で形成しているが、凸部７２に必ずしも傾斜部を形成する必要はなく、傾斜部に代えて階段状に形成してもよい。 As shown in FIG. 2, the inclined portion 42 has an inclined surface 42 </ b> A that is smoothly continuous with the inclined surface 41 </ b> A along the housing short direction (the Y axis direction in the drawing). Therefore, the appearance quality of the connecting portion 4 is not impaired. Further, as shown in FIG. 2, when the cellular phone 1 is in the side-opened state, the inclined portion 42 is in the housing thickness direction from the main surface 3A of the lower housing 3 provided with the operation portion 14 (Z in FIG. In the axial direction). That is, the inclined portion 42 forms a part of the convex portion 72 of the connecting portion 4. In the present embodiment, the convex portion 72 is formed by the inclined portion 42. However, the convex portion 72 does not necessarily have to be formed with the inclined portion, and may be formed in a step shape instead of the inclined portion.
　図５に示す収容部４４は、筐体短手方向（図中、Ｙ軸方向）に沿って、傾斜部４２の下に位置する。収容部４４は、ひけを避けるために、元々連結部４の肉厚部分を抜いて形成されている。また、収容部４４の内部には、磁石保持部４５が設けられており、磁石保持部４５には、携帯電話機１の横開きを検出するための開閉検出用の磁石７０が収容される。収容部４４の側面のうち、下筐体３の主面３Ａ側の側面はほぼ全面が開口する開口部４４Ａを有する。 The housing portion 44 illustrated in FIG. 5 is located below the inclined portion 42 along the short side direction of the housing (in the Y-axis direction in the drawing). The housing portion 44 is originally formed by removing the thick portion of the connecting portion 4 in order to avoid sink marks. In addition, a magnet holding unit 45 is provided inside the housing unit 44, and the magnet holding unit 45 houses a magnet 70 for open / close detection for detecting the lateral opening of the mobile phone 1. Among the side surfaces of the housing portion 44, the side surface on the main surface 3A side of the lower housing 3 has an opening 44A that is substantially entirely open.
　ここで、図５に示すように、横開きを検出するための開閉検出用磁石７０が収容される磁石保持部４５は、操作部１４が設けられている下筐体３の主面３Ａから突出する傾斜部４２の下に位置する。さらに、図２に示すように、磁石保持部４５に収容される開閉検出用磁石７０は、筐体短手方向（図中、Ｙ軸方向）において、中央付近に位置している。 Here, as shown in FIG. 5, the magnet holding portion 45 in which the open / close detection magnet 70 for detecting lateral opening is accommodated protrudes from the main surface 3A of the lower housing 3 in which the operation portion 14 is provided. Located below the inclined portion 42. Furthermore, as shown in FIG. 2, the open / close detection magnet 70 housed in the magnet holding portion 45 is located near the center in the housing short direction (in the Y-axis direction in the drawing).
　図６に示すように、筐体長手方向（図中、Ｘ軸方向）から開口部４４Ａを見ると、磁石保持部４５に設けられた開閉検出用の磁石７０が見える。また、開口部４４Ａの一部は操作部１４が設けられている下筐体３の主面３Ａから、筐体厚み方向（図中Ｚ軸方向）において突出するので、図５に示すように、連結部４の開口部４４Ａは外観シート４７で覆れているため携帯電話機１は、外観品位を損なわない。
　なお、収容部４４には、筐体短手方向（図中、Ｙ軸方向）にそって、開口部４４Ｂから第１ヒンジ２８が挿通される。 As shown in FIG. 6, when the opening 44A is viewed from the longitudinal direction of the case (in the X-axis direction in the drawing), the magnet 70 for open / close detection provided in the magnet holder 45 can be seen. In addition, since a part of the opening 44A protrudes from the main surface 3A of the lower housing 3 provided with the operation unit 14 in the housing thickness direction (the Z-axis direction in the drawing), as shown in FIG.
