Description

この発明は、2つの筐体を相互に回動可能に連結してなる携帯電話機、PDA(Personal Digital Assistants)等の携帯端末装置に関する。   The present invention relates to a mobile terminal device such as a mobile phone, PDA (Personal Digital Assistants), etc., in which two casings are rotatably connected to each other.

従来、2つの筐体を備えた携帯端末装置としては、互いに重ね合わせ可能に配置された2つの筐体をこれら両筐体の重ね合わせ方向に沿う軸線を中心に2つの筐体を相互に回動可能に連結する連結部を備えたものがある(例えば、特許文献1参照。)。このような構成の携帯端末装置においては、連結部を構成する回転軸に2つの筐体の内部空間を相互に連通させる貫通孔が形成されている。この貫通孔には、2つの筐体内部に固定された回路基板を相互に電気的に接続するケーブルが配されている。   Conventionally, as a mobile terminal device having two casings, two casings arranged so as to be superposed on each other are rotated around each other around an axis along the overlapping direction of the two casings. There is one provided with a connecting portion that is movably connected (for example, see Patent Document 1). In the mobile terminal device having such a configuration, a through-hole that allows the internal spaces of the two casings to communicate with each other is formed on the rotating shaft that forms the connecting portion. Cables that electrically connect the circuit boards fixed in the two housings to each other are disposed in the through holes.

ケーブルは、両筐体に配された回路基板の間でやりとりされる電気信号を伝達したり、一方の筐体に設けられたバッテリーから他方の筐体に電力を供給するものである。また、このケーブルは電気信号の種類毎に別個に配されるため、携帯端末装置の機能が増加するとケーブルの本数が増えることになる。
なお、一般に携帯端末装置は、鞄や衣服のポケット等に収容して携行することを目的としているため、その小型化、薄型化が要求されており、これに伴って、前述の連結部を含む携帯端末装置の構成部品の小型化が要求されている。
特開平7−288860号公報
The cable transmits an electrical signal exchanged between circuit boards arranged in both housings, or supplies power from a battery provided in one housing to the other housing. Further, since this cable is separately arranged for each type of electrical signal, the number of cables increases as the function of the mobile terminal device increases.
In general, since the portable terminal device is intended to be carried in a bag or a pocket of clothes, etc., it is required to be reduced in size and thickness, and accordingly, includes the above-described connecting portion. There is a demand for downsizing of components of portable terminal devices.

また、2つの筐体を相互に回動させる際にはケーブルが回動方向に捻れるため、両筐体の相対的な回動を繰り返しても両筐体内に設けられた回路基板間の電気的信号を確実に伝達できる信頼性の高い携帯端末装置を提供することは難しいものであった。
However, in recent years, there has been a tendency to add various functions such as a camera function and a game function to the mobile terminal device, and it has been necessary to insert a large number of cables through the through hole of the rotating shaft. For this reason, it is difficult to reduce the size of the connecting portion, and there is a problem that there is a limit to the size reduction of the mobile terminal device.
In addition, when the two cases are rotated relative to each other, the cable is twisted in the direction of rotation, so that the electrical circuit between the circuit boards provided in both cases is not affected by repeated relative rotation of the cases. It has been difficult to provide a highly reliable portable terminal device that can reliably transmit a target signal.

そこで、本発明の目的は、上述した事情に鑑みてなされたもので、厚み方向に重ね合わせ可能に配置される2つの筐体を、これら両筐体の重ね合わせ方向に延びる軸線を中心として回動できるように連結手段を介して連結した携帯端末装置において、小型化を図ると共に、信頼性の高い携帯端末装置を提供することにある。   Accordingly, an object of the present invention has been made in view of the above-described circumstances, and two housings arranged so as to be superposed in the thickness direction are rotated around an axis extending in the superposing direction of the two housings.

コイルばね65は、第1の接続部材61の孔61aに挿入されており、その一端が第2の接続部材63に当接している。また、コイルばね65の他端は、第1の接続部材61や第1の回路基板31の表面31aに当接しており、第2の接続部材63を第1の接続部材61の孔61aの開口部から突出させる方向に付勢している。
以上のように構成された電気接続部60は、2つの筐体2,3を基準軸線L1方向に相互に引き離す方向に付勢している。このため、基準軸線L1方向に関する2つの筐体の相対的な位置関係を安定させることができる。
The coil spring 65 is inserted into the hole 61 a of the first connection member 61, and one end thereof is in contact with the second connection member 63. The other end of the coil spring 65 is in contact with the first connecting member 61 and the surface 31 a of the first circuit board 31, and the second connecting member 63 is opened in the hole 61 a of the first connecting member 61. It is energized in the direction of protruding from the part.

以上のように構成された携帯電話機1の作用について説明する。
この携帯電話機1を鞄や衣服のポケットに収容して携行する場合には、図3に示すように、2つの筐体2,3を互いに重ね合わせて閉じた状態とする。この状態において、例えば、通話の着信があった場合には、第2の操作部17を操作して着信を受けることにより通話を開始し、受話器として機能するスピーカー部23及び送話器として機能する電気音響変換部25により通話を行う。この通話の際には、携帯電話機1が受信した音声信号に応じて、第1の回路基板31に設けられた発光部71から第2の回路基板33に設けられた受光部77に光信号が伝達され、第2の回路基板33を介してスピーカー部23から音声が出力される。
また、例えば、着信したメールやインターネットを閲覧する場合には、第2の操作部17を操作して表示部21に表示される各種情報を視認する。この閲覧の際も、第2の操作部17の入力信号に応じて、第1の回路基板31から第2の回路基板33に光信号が伝達され、表示部21に各種情報が表示される。
The operation of the mobile phone 1 configured as described above will be described.
When the cellular phone 1 is carried in a bag or a pocket of clothes, the two casings 2 and 3 are overlapped and closed as shown in FIG. In this state, for example, when there is an incoming call, the second operation unit 17 is operated to receive the incoming call to start the call, and function as a speaker unit 23 and a transmitter functioning as a receiver. A call is made by the electroacoustic conversion unit 25. During this call, an optical signal is sent from the light emitting unit 71 provided on the first circuit board 31 to the light receiving unit 77 provided on the second circuit board 33 in accordance with the audio signal received by the mobile phone 1. Then, the sound is output from the speaker unit 23 via the second circuit board 33.
For example, when browsing an incoming mail or the Internet, the second operation unit 17 is operated to visually check various information displayed on the display unit 21. Also during this browsing, an optical signal is transmitted from the first circuit board 31 to the second circuit board 33 in accordance with an input signal of the second operation unit 17, and various information is displayed on the display unit 21.

また、例えば、メール等の文章を作成したり、電話番号を入力する場合には、第1の操作部7を操作するため、図1に示すように、第2の筐体3を第1の筐体2に対して基準軸線L1を中心に180°回動させ、第1の操作部7を外方に露出させるように2つの筐体2,3を相互に開く。
この際には、第2の筐体3、第2の回路基板33及び円形プレート49が、第1の筐体2に固定された第1の回路基板13、軸41及び電気接続部60に対して基準軸線L1を中心に回転する。また、円形プレート49が皿ばね53に対して摺動する。
なお、この状態においても、電気接続部60の先端はコイルばね65により第2の回路基板33に接触した状態に保持される。
Further, for example, when creating a text such as e-mail or inputting a telephone number, the second casing 3 is attached to the first casing 3 as shown in FIG. The two cases 2 and 3 are opened with respect to the case 2 so that the first operation unit 7 is exposed to the outside by rotating 180 ° about the reference axis L1.
At this time, the second casing 3, the second circuit board 33, and the circular plate 49 are connected to the first circuit board 13, the shaft 41, and the electrical connection portion 60 fixed to the first casing 2. And rotate around the reference axis L1. Further, the circular plate 49 slides with respect to the disc spring 53.
Even in this state, the tip of the electrical connection portion 60 is held in contact with the second circuit board 33 by the coil spring 65.

そして、2つの筐体2,3を相互に開いた状態において、例えば、第1の操作部7のテンキー等を押圧して文字や記号を入力した場合には、この入力信号に応じて、第1の回路基板31から第2の回路基板33に光信号が伝達され、表示部21に文字や記号が表示されることになる。
また、例えば、通話を行う場合には、受信した音声信号を発光部71から受光部77に光信号により伝達し、第2の回路基板33を介して受話器として機能する電気音響変換部25から音声を出力する。
In the state where the two casings 2 and 3 are opened to each other, for example, when a character or a symbol is input by pressing the numeric keypad or the like of the first operation unit 7, An optical signal is transmitted from the first circuit board 31 to the second circuit board 33, and characters and symbols are displayed on the display unit 21.
For example, when a call is made, the received audio signal is transmitted from the light emitting unit 71 to the light receiving unit 77 as an optical signal, and the audio signal is transmitted from the electroacoustic conversion unit 25 functioning as a receiver via the second circuit board 33. Is output.

上記のように、この携帯電話機1によれば、各筐体2,3に設けられた回路基板31,33間の情報伝達が光通信手段70により行われるため、2つの筐体2,3を相互に回動させても2つの回路基板31,33の間で各種制御信号の伝達を確実に行うことが可能な携帯電話機1を提供することができる。
また、従来のように、2つの回路基板31,33間に信号を伝達する多数のケーブルが不要となるため、軸41の貫通孔41aを小さく形成して軸41の小型化を図り、携帯電話機1の小型化を図ることができる。
As described above, according to the cellular phone 1, information transmission between the circuit boards 31 and 33 provided in the respective casings 2 and 3 is performed by the optical communication means 70.

Further, even when the two casings 2 and 3 are rotated around the reference axis L 1, the two circuit boards 31 and 33 are electrically connected to each other by the shaft 41 and the electrical connection portion 60. Therefore, there is no problem such as twisting of the cable as in the prior art. Therefore, power can be reliably supplied from the first housing 2 to the second housing 3, and the two housings 2 and 3 can be rotated 360 ° or more with respect to the reference axis L1. Become. Therefore, handling of the mobile phone 1 becomes easy.
Furthermore, since the second connection member 63 of the electrical connection portion 60 is pressed against the second circuit board 33 by the coil spring 65, the electrical connection between the two circuit boards 31 and 33 can be reliably held. .

また、各回路基板31,33に発光部71,73及び受光部75,77を1つずつ設けるとしたが、これに限ることはなく、複数の発光部及び受光部を設けるとしても構わない。この構成の場合には、2つの回路基板31,33間に伝達させる光信号の数を増やすことができるが、各受光部が検出する光の波長帯域の区分を細分化する必要がある。
In the above embodiment, each of the circuit boards 31 and 33 is provided with the annular light emitting parts 71 and 73 and the light receiving parts 75 and 77. However, the present invention is not limited thereto.

In the case of this configuration, the number of optical signals transmitted between the two circuit boards 31 and 33 can be increased, but it is necessary to subdivide the division of the wavelength band of light detected by each light receiving unit.

さらに、第1及び第2の回路基板31,33間に伝達される光信号の種類は、上記実施形態のものに限ることはなく、携帯電話機1に搭載される電子部品に応じて変えることができる。すなわち、例えば、第2の筐体3に撮影用のカメラを設けた場合には、カメラにおいて撮影した画像信号が、光信号によって第2の回路基板33から第1の回路基板31に伝達されることになる。また、例えば、第2の筐体3に別途操作部を設けた場合には、この操作部の入力信号が、光信号によって第2の回路基板33から第1の回路基板31に伝達されることになる。   Furthermore, the type of the optical signal transmitted between the first and second circuit boards 31 and 33 is not limited to that of the above-described embodiment, and can be changed according to the electronic component mounted on the mobile phone 1. it can. That is, for example, when a camera for photographing is provided in the second housing 3, an image signal photographed by the camera is transmitted from the second circuit board 33 to the first circuit board 31 by an optical signal. It will be. Further, for example, when an operation unit is separately provided in the second housing 3, an input signal of the operation unit is transmitted from the second circuit board 33 to the first circuit board 31 by an optical signal. become.

また、2つの筐体2,3を相互に閉じた状態においては、電気音響変換部25をマイクロフォンとして機能させるとしたが、これに限ることはなく、少なくとも2つの筐体2,3を相互に閉じた状態においても通話可能な構成があればよい。
すなわち、2つの筐体2,3を相互に閉じた状態においては、突起部11によって第1の筐体2の先端部2cと第2の筐体3の先端部3cとの間に隙間が形成されている。このため、この状態においては、第1の筐体2の先端部2cに設けられたマイクロフォン部9と第2の筐体3の基端部3bに設けられたスピーカー部23とにより通話を行うとしても構わない。
Further, in the state where the two casings 2 and 3 are closed to each other, the electroacoustic transducer 25 is made to function as a microphone. However, the present invention is not limited to this, and at least two casings 2 and 3 are mutually connected. It is sufficient if there is a configuration capable of making a call even in the closed state.
