LCD36はフレーム37により支持されており、フレーム37はリアケース32に固定されている。カメラユニット381及びステレオスピーカー382は、図6に示すように、フロントケース31及びリアケース32の前部に収納されている。   The LCD 36 is supported by a frame 37, and the frame 37 is fixed to the rear case 32. The camera unit 381 and the stereo speaker 382 are housed in front portions of the front case 31 and the rear case 32 as shown in FIG.

図9は図1(a)の携帯電話機1の側方から見た断面図であり、図10は図1(c)の携帯電話機1の側方から見た断面図である。図9及び図10に示すように、本体2は、前方に向かって薄くなる形状をしている。   9 is a cross-sectional view seen from the side of the mobile phone 1 in FIG. 1A, and FIG. 10 is a cross-sectional view seen from the side of the mobile phone 1 in FIG. As shown in FIGS. 9 and 10, the main body 2 has a shape that becomes thinner toward the front.

蓋体3は、前方に向かって厚くなる形状をしている。また、蓋体3の前端部はさらに厚みを増しており、カメラユニット381やステレオスピーカー382等、厚みがあるデバイスが収納される肉厚部30となっている。   The lid 3 has a shape that becomes thicker toward the front. Further, the front end portion of the lid 3 is further increased in thickness, and is a thick portion 30 in which a thick device such as the camera unit 381 or the stereo speaker 382 is accommodated.

肉厚部30は、図9に示すように、閉状態においても、本体2の前方に位置し、本体2の上に重ね合わせられていない。このため、厚みがあるデバイスを前端部に収納しても、閉状態における携帯電話機1の厚みが増すことがない。   As shown in FIG. 9, the thick portion 30 is located in front of the main body 2 and is not superimposed on the main body 2 even in the closed state. For this reason, even if a thick device is stored in the front end, the thickness of the cellular phone 1 in the closed state does not increase.

図9に示すように、閉状態において、本体2及び蓋体3の後端面は、ともに前方に向かって上がる傾斜面を構成しており、蓋体3の後端部の断面形状は鋭角になっている。また、蓋体3のカーソルキー351は、後端部の傾斜面に設けられている。   As shown in FIG. 9, in the closed state, the rear end surfaces of the main body 2 and the lid body 3 both constitute an inclined surface that rises forward, and the cross-sectional shape of the rear end portion of the lid body 3 is an acute angle. ing. The cursor key 351 of the lid 3 is provided on the inclined surface at the rear end.

このため、図10に示すように、開状態において、テンキー212の前部まで蓋体3の後端部を前進させ、テンキー212を露出させると、テンキー212の前方に断面形状が鋭角な蓋体3の後端部が位置する。テンキー212が設けられた本体2の上面と、カーソルキー351が設けられた蓋体3の後端部の傾斜面とが連続するため、テンキー212及びカーソルキー351を操作するときに指の移動が容易となる。   Therefore, as shown in FIG. 10, when the rear end of the lid 3 is advanced to the front of the numeric keypad 212 in the open state and the numeric keypad 212 is exposed, the lid has a sharp cross section in front of the numeric keypad 212. 3 is located at the rear end. Since the upper surface of the main body 2 provided with the numeric keypad 212 and the inclined surface of the rear end portion of the lid 3 provided with the cursor key 351 are continuous, the finger is moved when operating the numeric keypad 212 and the cursor key 351. It becomes easy.

また、図10に示すように、開状態においては、本体2の薄い前端部と、蓋体3の薄い後端部とが重なり合うため、開状態における携帯電話の厚みがほぼ一様になる。このため、従来のスライド式の携帯電話のように前後方向の中央部分で厚みが2倍になるという不具合がなく、使い勝手がよい。   Also, as shown in FIG. 10, in the open state, the thin front end portion of the main body 2 and the thin rear end portion of the lid 3 overlap each other, so that the thickness of the mobile phone in the open state becomes substantially uniform. Therefore, there is no inconvenience that the thickness is doubled at the center portion in the front-rear direction as in a conventional slide-type mobile phone, and it is easy to use.

FPC5は両端部にメイン基板側コネクタ51とサブ基板側コネクタ52とを備え、メイン基板25と、後述するサブ基板35とを接続する。閉状態においては、図9に示すように、メイン基板側コネクタ51が前方に、サブ基板側コネクタ52が後方に位置している。閉状態から、蓋体3を前方に移動させると、サブ基板側コネクタ52が前進し、図10に示すようにメイン基板側コネクタ51よりも前方に位置する開状態になる。   The FPC 5 includes a main board side connector 51 and a sub board side connector 52 at both ends, and connects the main board 25 and a sub board 35 described later. In the closed state, as shown in FIG. 9, the main board side connector 51 is located on the front side and the sub board side connector 52 is located on the rear side. When the lid 3 is moved forward from the closed state, the sub-board-side connector 52 moves forward and enters an open state that is located forward of the main-board-side connector 51 as shown in FIG.

次に、本体2及び蓋体3を、蓋体3が本体2に対して前後方向に移動するように取り付けるスライドユニット4について説明する。図11は本体2と蓋体3との間を接続するスライドユニットの取付構造を示す分解斜視図である。スライドユニット4は、図12に示すように、ベース41と、一対のガイドレール42と、レール43と、一対のスペーサー44と、一対のトーションバネ45とから概略構成される。   Next, the slide unit 4 that attaches the main body 2 and the lid 3 so that the lid 3 moves in the front-rear direction with respect to the main body 2 will be described. FIG. 11 is an exploded perspective view showing a mounting structure of a slide unit that connects between the main body 2 and the lid 3. As shown in FIG. 12, the slide unit 4 is generally composed of a base 41, a pair of guide rails 42, a rail 43, a pair of spacers 44, and a pair of torsion springs 45.

ベース41及びガイドレール42は、ネジ263、264により、本体2のフロントケース21に取り付けられる。また、レール43は、ネジ393、394、395により、蓋体3のリアケース32に取り付けられる。   The base 41 and the guide rail 42 are attached to the front case 21 of the main body 2 by screws 263 and 264. The rail 43 is attached to the rear case 32 of the lid 3 by screws 393, 394, and 395.

The base 41 includes a base part 411, a connection part 412, and a guide rail fixing part 413. As shown in FIG. 11, the base 411 and the guide rail fixing portion 413 are fixed to the front portion of the front case 21 of the main body 2. A connecting portion 412 is provided at the left and right ends of the base portion 411 so as to protrude toward the lid 3 side. The base 411 is provided with an FPC insertion hole 414 through which the FPC 5 is passed.

接続部412は基部411とガイドレール固定部413とを上下に離間させて接続する。ガイドレール固定部413は左右の接続部412にそれぞれ接続されている。ガイドレール固定部413には、ガイドレール42が固定される。   The connection portion 412 connects the base portion 411 and the guide rail fixing portion 413 with the vertical separation. The guide rail fixing portion 413 is connected to the left and right connecting portions 412. The guide rail 42 is fixed to the guide rail fixing portion 413.

ベース41の後方部の、基部411とガイドレール固定部413との間には、トーションバネ45のベース側腕451の端部が回動自在に固定されるベース側支軸415が設けられる。なお、基部411とガイドレール固定部413との間の空間は、トーションバネ45が動くための軌道となる。   Between the base part 411 and the guide rail fixing part 413 at the rear part of the base 41, a base side support shaft 415 to which the end part of the base side arm 451 of the torsion spring 45 is rotatably fixed is provided. The space between the base 411 and the guide rail fixing part 413 serves as a track for the torsion spring 45 to move.

ガイドレール42は、基部421と、接続部422と、スペーサー保持部423とからなる。基部421はベース41のガイドレール固定部413に固定される。接続部422はスペーサー保持部423をガイドレール固定部413から離間させて基部421に接続する。スペーサー保持部423はガイドレール固定部413との間に、スペーサー44を介してレール43を摺動自在に保持する。   The guide rail 42 includes a base part 421, a connection part 422, and a spacer holding part 423. The base portion 421 is fixed to the guide rail fixing portion 413 of the base 41. The connecting portion 422 connects the spacer holding portion 423 to the base portion 421 while separating from the guide rail fixing portion 413. The spacer holding part 423 holds the rail 43 slidably between the guide rail fixing part 413 via the spacer 44.

また、ベース41及びガイドレール42の後端部には、後方に突出した係合片416、424がそれぞれ設けられている。係合片416、424は、図14に示すように、リアケース32に設けられた係合孔320と係合し、本体2に対して前方向に摺動する蓋体3を停止させる。係合片416、424が係合孔320と係合していることで、開状態において蓋体3の前部分に下向きの力がかかった場合でも、蓋体3の後端が本体2から浮き上がることを防ぎ、開状態における携帯電話機1の剛性を高めることができる。   Engagement pieces 416 and 424 projecting rearward are provided at the rear ends of the base 41 and the guide rail 42, respectively. As shown in FIG. 14, the engagement pieces 416 and 424 engage with an engagement hole 320 provided in the rear case 32, and stop the lid body 3 that slides forward with respect to the main body 2. Since the engagement pieces 416 and 424 are engaged with the engagement holes 320, the rear end of the lid 3 is lifted from the main body 2 even when a downward force is applied to the front portion of the lid 3 in the open state. This can prevent this and increase the rigidity of the mobile phone 1 in the open state.

レール43は、固定部431と、接続部432と、スペーサー固定部433と、連結部434とからなる。左右一対の固定部431は、リアケース32に前後方向に平行に固定される。   The rail 43 includes a fixing portion 431, a connection portion 432, a spacer fixing portion 433, and a connecting portion 434. The pair of left and right fixing portions 431 are fixed to the rear case 32 in parallel in the front-rear direction.

接続部432は、スペーサー固定部433をリアケース32から離間させて固定部431と接続する。スペーサー固定部433は左右一対のスペーサー44を前後方向に平行に固定する。また、スペーサー固定部433の前端には上方へ突出する突出部436が設けられている。突出部436は、ガイドレール42の前端と当接し、ガイドレール42及びベース41に対して後方へ摺動するレール43を停止させる。   The connecting portion 432 connects the spacer fixing portion 433 to the fixing portion 431 by separating the spacer fixing portion 433 from the rear case 32. The spacer fixing portion 433 fixes the pair of left and right spacers 44 in parallel in the front-rear direction. A protrusion 436 that protrudes upward is provided at the front end of the spacer fixing portion 433. The protruding portion 436 abuts on the front end of the guide rail 42 and stops the rail 43 that slides backward with respect to the guide rail 42 and the base 41.

連結部434は、左右一対の固定部431を連結する。連結部434の上面には、FPC5のサブ基板側コネクタ52が配置される。連結部434の前端左右側部の下面には、トーションバネ45のレール側腕452の端部が回動自在に固定されるレール側支軸435が取り付けられる。左右のレール側支軸435が取り付けられる部分の間には、FPC5が通される。   The connecting part 434 connects the pair of left and right fixing parts 431. On the upper surface of the connecting portion 434, the sub-board-side connector 52 of the FPC 5 is disposed. A rail-side support shaft 435 to which the end of the rail-side arm 452 of the torsion spring 45 is rotatably fixed is attached to the lower surface of the front end left and right side portions of the connecting portion 434. The FPC 5 is passed between the portions to which the left and right rail side support shafts 435 are attached.

スペーサー44は断面コ字形状をしており、レール43のスペーサー固定部433を被覆し、ベース41及びガイドレール42をレール43に対して摺動自在とする。スペーサー44の素材としては、ベース41及びガイドレール42との摩擦係数が小さい素材を用いることが好ましい。   The spacer 44 has a U-shaped cross section, covers the spacer fixing portion 433 of the rail 43, and makes the base 41 and the guide rail 42 slidable with respect to the rail 43. As a material of the spacer 44, it is preferable to use a material having a small coefficient of friction with the base 41 and the guide rail.

トーションバネ45は、ベース側腕451と、レール側腕452と、ベース側腕451及びレール側腕452を接続するコイル部453とからなる。コイル部453はベース側腕451及びレール側腕452を広げるように付勢している。ベース側腕451の端部はベース側支軸415に、レール側腕452の端部をレール側支軸435に、それぞれ回動自在に固定されている。トーションバネ45は、ベース側腕451の端部とレール側腕452の端部との間隔が広がるように付勢されているため、ベース側支軸415とレール側支軸435とを、互いに遠ざかる方向へ付勢する。   The torsion spring 45 includes a base side arm 451, a rail side arm 452, and a coil portion 453 that connects the base side arm 451 and the rail side arm 452. The coil portion 453 biases the base side arm 451 and the rail side arm 452 so as to spread. The end of the base side arm 451 is fixed to the base side support shaft 415 and the end of the rail side arm 452 is fixed to the rail side support shaft 435 so as to be rotatable. Since the torsion spring 45 is biased so that the distance between the end of the base side arm 451 and the end of the rail side arm 452 is widened, the base side support shaft 415 and the rail side support shaft 435 are moved away from each other. Energize in the direction.

図13は図1の携帯電話機1の形態に対応するスライドユニット4の形態を示す斜視図である。図13(a)は本体2の上に蓋体3が重ね合わせられた閉状態であり、レール43前端の突出部436がガイドレール42の前端に当接している。このときレール側支軸435はベース側支軸415よりも後方に位置するため、トーションバネ45の弾性力は、レール側支軸435をベース側支軸415に対して遠ざかる方向、すなわち後方に付勢している。   FIG. 13 is a perspective view showing a form of the slide unit 4 corresponding to the form of the mobile phone 1 of FIG. FIG. 13A shows a closed state in which the lid 3 is superimposed on the main body 2, and the protrusion 436 at the front end of the rail 43 is in contact with the front end of the guide rail 42. At this time, since the rail-side support shaft 435 is positioned rearward of the base-side support shaft 415, the elastic force of the torsion spring 45 is applied in a direction in which the rail-side support shaft 435 moves away from the base-side support shaft 415, that is, rearward. It is fast.

閉状態の携帯電話の本体2を掌に載せ、親指で蓋体3を前方へ押圧すると、トーションバネ45の弾性力に抗して蓋体3が前進し、図13(b)に示す中間状態となる。このときレール側支軸435とベース側支軸415とが左右に並んでいるので、トーションバネ45の弾性力は、レール側支軸435をベース側支軸415に対して遠ざかる方向、すなわちレール43と垂直な左右方向に作用している。このため、中間状態は、トーションバネ45が蓋体3を前後いずれの方向にも付勢しない不安定な状態である。   When the body 2 of the cellular phone in the closed state is placed on the palm and the lid 3 is pushed forward with the thumb, the lid 3 moves forward against the elastic force of the torsion spring 45, and the intermediate state shown in FIG. It becomes. At this time, since the rail-side support shaft 435 and the base-side support shaft 415 are arranged side by side, the elastic force of the torsion spring 45 causes the rail-side support shaft 435 to move away from the base-side support shaft 415, that is, the rail 43. Acts in the vertical direction. For this reason, the intermediate state is an unstable state in which the torsion spring 45 does not urge the lid 3 in any of the front and rear directions.

中間状態からさらに親指で蓋体3を前方へ押圧すると、レール側支軸435がベース側支軸415よりも前方へ位置するため、トーションバネ45はレール側支軸435をベース側支軸415から遠ざける方向、すなわち前方に付勢する。このため、蓋体3を中間状態よりも前方へ押圧すると、以降は蓋体3を前方へ押圧しなくても、トーションバネ45の弾性力により、蓋体3が前進する。   When the lid 3 is further pushed forward with the thumb from the intermediate state, the rail-side support shaft 435 is positioned forward of the base-side support shaft 415, so that the torsion spring 45 causes the rail-side support shaft 435 to move from the base-side support shaft 415. It urges away, that is, forward. For this reason, when the lid 3 is pressed forward from the intermediate state, the lid 3 moves forward by the elastic force of the torsion spring 45 without pressing the lid 3 forward thereafter.

蓋体3は、図14に示すように、リアケース32に設けられた係合孔320に、ベース41及びガイドレール42の後端部に設けられた係合片416、424が係合することで、前進を停止し、開状態となる。開状態において蓋体3の前部分に下向きの力がかかった場合には、蓋体3の後端が本体2から浮き上がろうとするが、係合孔320に係合片416、424が係合しているので、蓋体3がベース41及びガイドレール42から浮き上がることを防いでいる。また、本体2のフロントケース21の係止部210により、ベースの後端が固定されているので、ベース41が蓋体3とともに浮き上がることを防いでおり、開状態における携帯電話機1の剛性を高めている。   As shown in FIG. 14, the lid 3 has engaging pieces 416 and 424 provided at the rear end portions of the base 41 and the guide rail 42 engaged with engaging holes 320 provided in the rear case 32. Then, the forward movement is stopped and the open state is entered. When a downward force is applied to the front portion of the lid 3 in the open state, the rear end of the lid 3 tends to float from the main body 2, but the engagement pieces 416 and 424 are engaged with the engagement hole 320. Therefore, the lid 3 is prevented from floating from the base 41 and the guide rail 42. Further, since the rear end of the base is fixed by the locking portion 210 of the front case 21 of the main body 2, the base 41 is prevented from being lifted together with the lid 3, and the rigidity of the mobile phone 1 in the open state is increased. ing.

開状態から蓋体3を後方に下げる場合にも同様に、中間状態まではトーションバネ45の弾性力に抗して力を作用させる必要があるが、中間状態以降はトーションバネ45の弾性力により、蓋体3が後方に移動する。   Similarly, when the lid 3 is lowered rearward from the open state, it is necessary to apply a force against the elastic force of the torsion spring 45 until the intermediate state. The lid 3 moves backward.

なお、ベース側腕451の長さと、コイル部453の半径とを足した長さ、すなわちベース側支軸415を中心とするコイル部453の可動半径は、レール側支軸435とベース側支軸415との最短距離よりも短い。このため、トーションバネ45のコイル部453は、レール側支軸435の軌道よりも側方の軌道を移動する。レール側支軸435の間はFPC5が移動する軌道となるが、トーションバネ45の軌道はFPC5の軌道よりも側方であるため、トーションバネ45がFPC5の移動を妨げることはない。   The length obtained by adding the length of the base side arm 451 and the radius of the coil portion 453, that is, the movable radius of the coil portion 453 with the base side support shaft 415 as the center, is the rail side support shaft 435 and the base side support shaft. Shorter than the shortest distance to 415. For this reason, the coil portion 453 of the torsion spring 45 moves along a track that is lateral to the track of the rail-side support shaft 435. The FPC 5 moves between the rail-side support shafts 435. However, since the orbit of the torsion spring 45 is lateral to the FPC 5 orbit, the torsion spring 45 does not hinder the movement of the FPC 5.

同様に、レール側腕452の長さと、コイル部453の半径とを足した長さ、すなわちレール側支軸435を中心とするコイル部453の可動半径は、レール側支軸435とベース側支軸415との最短距離よりも短いため、トーションバネ45のコイル部453は、ベース側支軸415の軌道よりも内側の軌道を移動する。   Similarly, the length obtained by adding the length of the rail side arm 452 and the radius of the coil portion 453, that is, the movable radius of the coil portion 453 centered on the rail side support shaft 435, is the rail side support shaft 435 and the base side support. Since it is shorter than the shortest distance from the shaft 415, the coil portion 453 of the torsion spring 45 moves on the track inside the track on the base side support shaft 415.

以上説明したように、本発明の実施の形態では、蓋体2のリアケース32に設けられた係合孔320に、ベース41及びガイドレール42の後端部に設けられた係合片416、424を係合させることで、開状態において蓋体3の前側部分に下向きの力がかかった場合でも、蓋体3の後端が本体2から浮き上がることを防ぎ、開状態における携帯電話機1の剛性を高めることができる。   As described above, in the embodiment of the present invention, the engagement piece 416 provided in the rear end portion of the base 41 and the guide rail 42 in the engagement hole 320 provided in the rear case 32 of the lid 2. By engaging 424, even when a downward force is applied to the front portion of the lid 3 in the opened state, the rear end of the lid 3 is prevented from floating from the main body 2, and the rigidity of the mobile phone 1 in the opened state is prevented. Can be increased.

なお、以上の実施の形態においては、スライド式の携帯電話機について説明したが、本発明はこれに限らず、例えばPDA等、その他の携帯情報端末に本発明を適用してもよい。また、上記のトーションバネ45の形状はコイル部453を1つ有するものであったが、複数のコイル部を有するものを用いてもよく、その他の具体的な細部構造についても適宜変更可能であることはもちろんである。   In the above embodiment, the slide type mobile phone has been described. However, the present invention is not limited to this, and the present invention may be applied to other portable information terminals such as a PDA. Further, the shape of the torsion spring 45 has one coil portion 453. However, one having a plurality of coil portions may be used, and other specific detailed structures can be appropriately changed. Of course.
