Description

【0001】
【発明の属する技術分野】
本発明は、デバイス装着構造に係り、特に可搬性を有する電子機器に設けられるデバイス装着構造に関する。
【0002】
【従来の技術】
例えばノート型パーソナルコンピュータ,モバイルコンピュータ,PDA(personal digital assistants),携帯電話機等の可搬性を備える電子機器は、その機能拡張のために板状挿入部を備える着脱自在の機能拡張デバイスを外部接続するためのスリット状スロットを備えるものが散見されるようになってきている。
【0003】
上記板状挿入部を備える着脱自在の機能拡張デバイスの例を図7〜9に示す。図7はフラッシュメモリーを内蔵した記憶機能拡張用の機能拡張デバイスとしてのメモリーカード100であり、図7(A)に示すように表面は全面平滑であり、図7(B)に示すように裏面も全面平滑であるが、その挿入端部側に内部メモリーと電子機器とを電気的に接続する接続端子101が設けられ、図7(C)に示すように側面から見ると長手方向(挿入方向)全域に渡って厚さが均一に設定されており、全体的に板状であることが分かる。
【0004】
また、図8には無線式情報通信機能拡張を図る機能拡張デバイスとしての無線LAN用カード(一例としてBluetooth(登録商標)等)110を示し、図9には撮像機能の拡張を図る機能拡張デバイスとしてのカメラカード120を示す。これらのカード110,120は図8(A),図9(A)に示すように板状挿入部111,121と、機能構成格納部112,122とを備えるためにメモリーカード100よりも機能構成格納部112,122の分だけ縦長となると共に、図8(B),図9(B)に示すように機能構成格納部112,122の部分は板状挿入部111,121と比較して厚みのある形状となっている。また、各カード110,120の挿入端部にはメモリーカード100と同様の接続端子113、123を備えている。
【0005】
ところが、図10に示すように機能拡張デバイスとしてカメラカード120を装着した場合、機能構成格納部122が外部に突出した状態になるので、図11に示すように、板状挿入部121の平板面に対して交差する方向,特に垂直となる方向に沿って機能構成格納部122に過度の荷重が加わった場合に、板状挿入部121と機能構成格納部122との境界で折れて破損を生じる可能性があった。また、カメラカード120の破損を生じない場合であっても、カード支持枠体152の破損を生じる可能性があった。また、同様のことが無線LANカード110でも問題となっていた。
【0006】
このような問題を解決させるため、機能拡張デバイスの突出部分の破損を防ぐカバー部材をスリット状スロットに装着された機能拡張デバイスに並行して設ける構造が考えられている(例えば、特許文献1参照)。

【発明が解決しようとする課題】
しかしながら、上記のような構造の場合、カバー部材により強度が増しても、落下の衝撃がそれ以上に強ければ、機能拡張デバイス及びカバー部材の両方の破損を招くことになるので根本的な解決にはならないという問題があった。
本発明は、より効果的に機能拡張デバイスの破損を防止することをその目的とする。
【0009】
【課題を解決するための手段】
請求項1記載の発明は、例えば図2,3,4に示すように、板状挿入部を備える着脱自在の機能拡張デバイス(120)を電子機器本体(1)に装着するための装着構造であって、板状挿入部(121)が挿入される挿入口(21)を有する分離体(20)と、電子機器本体の角部に分離体を嵌め込む嵌合凹部(30)と、挿入口に装着された板状挿入部の平板面に対して交差する方向に分離可能に分離体を嵌合凹部に保持すると共に,分離する方向の外力に対して弾性的な抗力により保持する保持手段(40)を備える、という構成を採っている。
【0010】
上記構成では、機能拡張デバイスを挿入する挿入口を有する分離体が保持手段により弾性的な抗力により嵌合凹部における保持状態を維持している。このため、機能拡張デバイスに対して外部から荷重が付加されて、かかる荷重が分離体の分離方向について保持手段による保持力である弾性的な抗力を超えると、分離体が嵌合凹部から分離し、機能拡張デバイスを加重から解放する。これにより、機能拡張デバイス或いはその周囲の構成の破損の発生が回避される。
【0011】
請求項2記載の発明は、請求項1記載の発明と同様の構成を備えると共に、例えば図2,3,4に示すように、保持手段(40)は、分離体(20)又は嵌合凹部(30)のいずれか一方に設けられた凸状部(41,42)と、他方に設けられ,凸状部が嵌合する凹状部(45,46)とを備え、凸状部と凹状部の少なくともいずれか一方が、その突出方向又は窪んだ方向に移動可能に弾性的に支持されている、という構成を採っている。
【0012】
上記構成では、請求項1記載の発明と同様の作用を奏すると共に、機能拡張デバイスに対する加重の付加を生じた場合に、弾性支持されている凸状部又は凹状部のいずれか一方が他方から徐々に退避し、ついには嵌合状態が解かれて分離体が嵌合凹部から分離する。
【0013】
請求項3記載の発明は、請求項2記載の発明と同様の構成を備えると共に、例えば図2,3,4に示すように、分離体(20)は板状挿入部(121)の挿入方向に沿った両側面(23,24)を有すると共に、嵌合凹部(30)はこれらの対向面(33,34)を有し、分離体の両側面(23,24)の挿入口(21)の近傍となる端部と嵌合凹部の両対向面(33,34)の対応する位置に凸状部(41)と凹状部(45)のいずれか一方と他方とを設け、同様に、分離体の両側面の挿入口の遠方となる端部と嵌合凹部の両対向面の対応する位置に凸状部(42)と凹状部(46)のいずれか一方と他方とを設ける、という構成を採っている。
【0014】
請求項3記載の発明は、請求項2記載の発明と同様の構成を備えると共に、機能拡張デバイスの挿入方向に略直交する方向について当該機能拡張デバイスが一方に加重を受けると、分離体は挿入口の近傍の二つの凸状部が凹状部から脱し、遠方の二つの凸状部が支点となって分離体の一端部が嵌合凹部から離間するように回動することとなる。これにより、機能拡張デバイスは一方向からの加重から解放されて機能拡張デバイス或いはその周囲の構成の破損が回避される。
また、機能拡張デバイスの挿入方向に略直交する方向について当該機能拡張デバイスが他方に加重を受けると、分離体は挿入口の遠方の二つの凸状部が凹状部から脱し、近傍の二つの凸状部が支点となって分離体の他端部が嵌合凹部から離間するように回動することとなる。これにより、機能拡張デバイスは他方向からの加重から解放されて機能拡張デバイス或いはその周囲の構成の破損が回避される。
【0015】
【発明の実施の形態】
(発明の実施形態の全体構成)
電子機器として本発明を携帯電話機に適用した場合について図1乃至図6に基づいて詳述する。図1は、携帯電話機1の正面図(A)と背面図(B)とD方向からみた上側面図(C)を示し、デバイス装着構造10を上部背面側に備える。
デバイス装着構造10は、板状挿入部を備える着脱自在の機能拡張デバイスを電子機器本体としての携帯電話機1に装着するための装着構造である。機能拡張デバイスとしては、例えば前述した各カード100,110,120が該当する。尚、本実施形態ではカメラカード120を用いて説明することとする。
図2(A)は上記図1(B)のデバイス装着構造10周辺の拡大図であり、同図において、デバイス装着構造10は、板状挿入部121を挿入する挿入口21を有する分離体20と、携帯電話機1の本体ケースの上側角部に分離体20を嵌め込む嵌合凹部30と、挿入口21に装着された板状挿入部121の平板面に対して略垂直な方向に分離可能に分離体20を嵌合凹部30に保持すると共に,分離する方向の外力に対して弾性的な抗力により保持する保持手段40を備えている。
【0016】
図2(B)は図1(C)の断面図である。
同図において嵌合凹部30は、携帯電話機1の外部ケースの一部として形成されるため、当該外装ケースと同じ素材、例えば樹脂,金属等から形成される。嵌合凹部30の背面側の内面の下部にはカメラカード120の接続端子123と接続される本体側接続端子31が設けられ、この背面側の内面は、分離体20の装着時にはその正面と対向し、さらにカメラカード120の挿入時にはその背面と対向する。
また、嵌合凹部30の内側両側面32,33は、図装着時の分離体20の各側面23,24とそれぞれ対向し、また各内側側面32,33には、いずれも、後述する保持手段40の上側凹状部45と下側凹状部46とが設けられている。
【0017】
(分離体)
図3は分離体20の外観図であり、図3(A)がその背面図,図3(B)はその左側面図,図3(C)はその平面図を示す。
分離体20は、携帯電話機1の外部ケースと同じ素材、例えば樹脂,金属等からなる内部中空の筐体であり、略直方体形状に形成されている。外部形状について詳細に説明すると、その背面(図3(A)に示す面)と上面とが曲面で円滑に連ねられ、分離体20が嵌合凹部30に装着された状態では、これら背面と上面とが携帯電話機1の外部に露出した状態となる。また、分離体20の背面は携帯電話機1の背面全体と同一面上となり、分離体の上面は携帯電話機1の上面全体と同一面上となる。また、分離体20の正面,両側面23,24,底面はそれぞれ嵌合凹部30の各内面と対向し接触することとなる。
【0018】
さらに、分離体20の上面には、装着された分離体20と嵌合凹部30との間にカメラカード120の板状挿入部121を挿入するために、切り欠き状の挿入口21が設けられている。かかる挿入口21は分離体20の上面における正面側の端縁部に沿って形成されている。
また、分離体20の正面には、カメラカード120の板状挿入部121の板面形状に合わせて形成された窪みである板状挿入部121の格納領域22が形成されている。
さらに、分離体20の両側面23,24にはいずれも、後述する保持手段40の上側凸状部41,下側凸状部42及びこれらの凸状部41,42を個別に支持する支持部43,44とが設けられている。
【0019】
(嵌合凹部)
図4は嵌合凹部30を示し、(A)がその背面図,(B)はその側方断面図,(C)は平面図を示す。
嵌合凹部30は、携帯電話機1の外部ケースの一部として形成されるため、当該外装ケースと同じ素材、例えば樹脂,金属等から形成される。嵌合凹部30の背面側の内面の下部にはカメラカード120の接続端子123と接続される本体側接続端子31が設けられ、この背面側の内面は、分離体20の装着時にはその正面と対向し、さらにカメラカード120の挿入時にはその背面と対向する。
また、嵌合凹部30の内側両側面32,33は、図装着時の分離体20の各側面23,24とそれぞれ対向し、また各内側側面32,33には、いずれも、後述する保持手段40の上側凹状部45と下側凹状部46とが設けられている。
【0020】
(保持手段)
保持手段40は、分離体20の両側面23,24の上部と下部とにそれぞれ設けられた上側凸状部41及び下側凸状部42と、各凸状部41,42を個別に弾性的に支持する支持部43,44と、嵌合凹部30の内側両側面32,33の上部と下部とにそれぞれ設けられた上側凹状部45及び下側凹状部46とを備えている。
【0021】
上側凸状部41と下側凸状部42とは、いずれも、球面状に形成され、分離体20の側面23,24に対して垂直外側に突出している。また、分離体20の各側面23,24の上側凸状部41は互いに同一高さに設けられ、また各下側凸状部42もまた互いに同一高さに設けられている。
【0022】
さらに、各凸状部41,42を支持する支持部43,44は、分離体20の側面23,24をU字状に切り欠いてアーム状とし、その先端部において各凸状部41,42を支持している。これらの各支持部43,44は分離体20の側面23,24の素材が有する弾性により、各凸状部41,42を弾性的に支持する。これにより、各凸状部41,42は図1の状態から押し込むと支持部43,44の弾性に基づく復帰力を生じることとなる。従って、分離体20は弾性を有する素材から形成することが望ましい。また、分離体20の側面部23,24のみ、ひいては各支持部43,44のみを弾性素材としても良い。
【0023】
上側凹状部45と下側凹状部46は、嵌合凹部30の内側両側面部32,33に設けられた上記各凸状部41,42が嵌合可能な円孔部である。また、嵌合凹部30の各内側側面32,33の各上側凹状部43はいずれも上記上側凸状部41と同一高さに設けられ、また各下側凹状部44はいずれも上記下側凸状部42と同一高さに設けられている。
【0024】
(デバイス装着構造の作用)
デバイス装着構造10の作用を図5,6に基づいて説明する。上記構成からなるデバイス装着構造10は、まず、各凸状部41,42を押し込んだ状態で分離体20を嵌合凹部30に装着する。装着時には、各凸状部41,42は各凹状部43,44に嵌合する。そして、外観上は図10に示した場合と同様にして、挿入口21からカメラカード120を挿入すると、その接続端子が嵌合凹部30の本体側接続端子31と接続され、カメラカード120は携帯電話機1のカメラとして機能する(図5(A),図6(A)の状態)。
【0025】
かかる状態において、分離体20はE方向から力が加わった場合、角度調節機側凹状部41から脱し、各上側凸状部44を支点として回動する。これにより、カメラカード120は正面方向からの荷重から解放され、機能構成格納部122と板状挿入部121との境界部の破損が回避される(図5(B)の状態)。
【0026】
一方、分離体20はF方向から力が加わった場合、角度調節機側凹状部41から脱し、各下側凸状部44を支点として回動する。これにより、カメラカード120は背面方向からの荷重から解放され、機能構成格納部122と板状挿入部121との境界部の破損が回避される(図6(B)の状態)。
【0027】
なお、上記作用から分かるように、各支持部43,44における弾性力は、前方又は後方からの加重により、カメラカード120の機能構成格納部122と板状挿入部121との境界に破損を生じない範囲に設定することが望ましく、さらには、破損を生じないように余裕を持ってより低めの弾性力の範囲内に設定することがより望ましい。
【0028】
(実施形態の効果)
上記実施形態では、デバイス装着構造10の分離体20の装着状態を維持する保持手段40の各凸状部41,42が弾性をもって支持部43,44により支持されていることから、カメラカード120等の機能拡張デバイスが外部から一定の方向に加重(板状挿入部121の平板面に垂直方向の加重成分を生じる方向の加重)が加わると、弾性力に抗して各凸状部41又は42が凹状部45又は46から脱し、機能拡張デバイスへの加重の付加から解放され、その破損を有効に回避することが可能である。
【0029】
また、保持手段40は、凸状部,支持部,凹状部を上側と下側の両側部に有しているので、機能拡張デバイスに対して前方と後方のいずれに対して加重が加えられた場合であっても、分離体20がいずれの加重方向にも回動することを可能とし、双方の加重から機能拡張デバイスを保護することが可能である。
【0030】
さらに、デバイス装着構造10は、分離体20と嵌合凹部30と保持手段40とからなる簡易な構成により、機能拡張デバイスの破損を有効に回避すること及びその材料強度を高める必要がないことからコスト面での低減を図ると共に生産性の向上を図ることが可能である。
特に、保持手段40は凹凸構造並びにU字状の切り欠きからなる支持部43,44にて構成されることから、特に、その形成が容易となると共に部品点数の低減が図られ、さらなるコスト面での低減を図ると共に生産性の向上を図ることが可能である。
【0031】
(その他)
機能拡張デバイスについては、板状挿入部を備えるものであれば何でも良く、特に機能についてはいかなるものであってもデバイス装着構造10は良好にその破損を防止する。また、前述したメモリーカード100のように電子機器の内部に完全に格納されるものである場合には、破損防止の機能を発揮しないが、そもそも破損が生じないので問題は生じない。また、デバイス装着構造10は、メモリーカード100のように電子機器の内部に完全に格納されるものであってもその正規の使用において何ら妨げとなるものではない。
【0032】
また、上記実施形態では、分離体20と嵌合凹部30との間に機能拡張デバイスを挿入する構成としたが、分離体20の上面にスリット状の挿入口を設けると共に当該分離体20の内部に機能拡張デバイスの板状挿入部を格納してしまう構成としても良い。但し、その場合、分離体20に、機能拡張デバイスの接続端子と電子機器の本体接続端子とを接続するための中継接続端子を設ける必要がある。
【0033】
また、デバイス装着構造を設ける電子機器については携帯電話機に限らず、板状挿入部を備える機能拡張デバイスを使用するものであれば何でも良く、例えば、ノート型パーソナルコンピュータ,モバイルコンピュータ,パームトップパーソナルコンピュータ,PDA等であっても良いことはいうまでもない。
【0034】
【発明の効果】
請求項1記載の発明によれば、機能拡張デバイスの挿入口を有する分離体が保持手段の弾性力により嵌合凹部における装着状態を維持することから、機能拡張デバイスに外部から荷重が付加された場合でも、破損を生じる過大な荷重となる前に保持手段の弾性的な保持力を超えて、分離体を嵌合凹部から分離させ、機能拡張デバイスを加重の付加状態から解放する。従って、機能拡張デバイスの破損を有効に回避する。また、分離体、嵌合凹部及び保持手段という簡易な構成で上記効果を実現すると共に各構成の増強を図る必要がないので、従来の場合と異なり、コスト高を回避すると共に生産性の向上を図ることが可能となる。
【0035】
請求項2記載の発明では、保持手段を凸状部と凹状部といずれかを弾性的に支持する支持部とから構成するので、簡易な構成から実現することが可能となり、さらなるコスト低減を図ると共に生産性の向上を図ることが可能となる。
【0036】
請求項3記載の発明は、分離体の挿入口の近傍と遠方となる端部に相当する各位置に凹状部と凸状部とを配置したので、機能拡張デバイスの挿入方向に略直交する双方向の加重に対して、分離体を回動させることを可能とし、より効果的に機能拡張デバイスの破損を防止することが可能となる。
また、挿入口の近傍又は遠方となる凸状部と凹状部とは嵌合状態が維持されるので、分離体の落下を防止することが可能となる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a device mounting structure, and more particularly to a device mounting structure provided in a portable electronic device.
[0002]
[Prior art]
For example, portable electronic devices such as a notebook personal computer, a mobile computer, a PDA (personal digital assistants), and a mobile phone are externally connected to a detachable function expansion device having a plate-shaped insertion portion for expanding the function. Are provided with slit-shaped slots for use.
[0003]
FIGS. 7 to 9 show examples of detachable function expansion devices provided with the above-mentioned plate-shaped insertion portion. FIG. 7 shows a memory card 100 as a function expansion device having a built-in flash memory for expanding a storage function. As shown in FIG. 7A, the front surface is entirely smooth, and as shown in FIG. Although the entire surface is also smooth, a connection terminal 101 for electrically connecting the internal memory and the electronic device is provided on the insertion end side thereof, and as shown in FIG. ) It can be seen that the thickness is set to be uniform over the entire area, and the whole is plate-shaped.
[0004]
8 shows a wireless LAN card (for example, Bluetooth (registered trademark)) 110 as a function expansion device for expanding a wireless information communication function, and FIG. 9 shows a function expansion device for expanding an imaging function. Is shown. As shown in FIGS. 8A and 9A, these cards 110 and 120 have plate-shaped insertion portions 111 and 121 and function configuration storage portions 112 and 122, respectively, and thus have a more functional configuration than the memory card 100. 8 (B) and 9 (B), the thickness of the functional configuration storage sections 112 and 122 is smaller than that of the plate-shaped insertion sections 111 and 121. It has a certain shape. The insertion ends of the cards 110 and 120 are provided with connection terminals 113 and 123 similar to those of the memory card 100.
[0005]
However, when the camera card 120 is mounted as a function expansion device as shown in FIG. 10, the function configuration storage unit 122 is projected outside, so that as shown in FIG. When an excessive load is applied to the functional configuration storage unit 122 along a direction intersecting with the vertical direction, particularly, a direction perpendicular to the functional configuration storage unit 122, the functional configuration storage unit 122 is broken at the boundary between the plate-shaped insertion unit 121 and the functional configuration storage unit 122 and breaks. There was a possibility. Further, even if the camera card 120 is not damaged, there is a possibility that the card support frame 152 may be damaged. In addition, the same problem has occurred in the wireless LAN card 110.
[0006]
In order to solve such a problem, a structure has been considered in which a cover member for preventing breakage of the protruding portion of the function expansion device is provided in parallel with the function expansion device mounted on the slit-shaped slot (for example, see Patent Document 1). ).
[0007]
[Patent Document 1]
JP-A-2002-298099
[0008]
[Problems to be solved by the invention]
However, in the case of the structure described above, even if the strength is increased by the cover member, if the impact of the drop is stronger than that, the damage of both the function expansion device and the cover member will be caused. There was a problem that should not be.
An object of the present invention is to prevent the function expansion device from being damaged more effectively.
[0009]
[Means for Solving the Problems]
The invention according to claim 1 is a mounting structure for mounting a detachable function expansion device (120) having a plate-shaped insertion portion to an electronic device main body (1) as shown in FIGS. A separator (20) having an insertion opening (21) into which the plate-like insertion portion (121) is inserted; a fitting recess (30) for fitting the separator into a corner of the electronic device main body; Holding means for holding the separation body in the fitting recess so as to be separable in a direction intersecting with the flat surface of the plate-shaped insertion part mounted on the housing, and holding by an elastic force against an external force in the separation direction ( 40).
[0010]
In the above configuration, the separation body having the insertion opening for inserting the function expansion device maintains the holding state in the fitting recess by the elastic resistance by the holding means.

(Operation of device mounting structure)
The operation of the device mounting structure 10 will be described with reference to FIGS. In the device mounting structure 10 having the above configuration, first, the separating body 20 is mounted in the fitting concave portion 30 with the respective convex portions 41 and 42 being pushed. At the time of mounting, the respective convex portions 41 and 42 are fitted into the respective concave portions 43 and 44. Then, when the camera card 120 is inserted through the insertion slot 21 in the same manner as that shown in FIG. 10, the connection terminal is connected to the main body side connection terminal 31 of the fitting recess 30, and the camera card 120 is portable. It functions as a camera of the telephone 1 (the state of FIGS. 5A and 6A).
[0025]
In this state, when a force is applied from the direction E, the separating body 20 comes off from the angle adjuster side concave portion 41 and rotates with each upper convex portion 44 as a fulcrum. Thereby, the camera card 120 is released from the load from the front direction, and damage to the boundary between the functional configuration storage unit 122 and the plate-like insertion unit 121 is avoided (the state of FIG. 5B).
[0026]
On the other hand, when a force is applied from the F direction, the separating body 20 comes off from the angle adjuster side concave portion 41 and rotates around each lower convex portion 44 as a fulcrum. Thereby, the camera card 120 is released from the load from the back direction, and the breakage of the boundary between the functional configuration storage unit 122 and the plate-shaped insertion unit 121 is avoided (the state of FIG. 6B).
[0027]
As can be seen from the above operation, the elastic force at each of the support portions 43 and 44 causes damage at the boundary between the functional component storage portion 122 and the plate-shaped insertion portion 121 of the camera card 120 due to the load from the front or the rear. It is desirable to set it in a range where there is no elastic force, and it is more desirable to set it in a range of a lower elastic force with a margin so as not to cause breakage.
[0028]
(Effects of the embodiment)
In the above embodiment, since the respective convex portions 41, 42 of the holding means 40 for maintaining the mounting state of the separation body 20 of the device mounting structure 10 are elastically supported by the support portions 43, 44, the camera card 120, etc. When the function expansion device of (1) is externally applied with a load in a certain direction (a load in a direction that generates a vertical load component on the flat surface of the plate-like insertion portion 121), each of the convex portions 41 or 42 resists the elastic force. Is released from the concave portion 45 or 46, and is released from the application of the weight to the function expansion device, and its breakage can be effectively avoided.
[0029]
In addition, since the holding means 40 has a convex portion, a support portion, and a concave portion on both upper and lower sides, a weight is applied to the functional expansion device either forward or backward. Even in this case, it is possible to allow the separating body 20 to rotate in any weighting direction, and to protect the function expansion device from both weights.
[0030]
Further, the device mounting structure 10 has a simple configuration including the separating body 20, the fitting recess 30, and the holding means 40, so that it is possible to effectively avoid the breakage of the function expansion device and to increase the material strength thereof. It is possible to reduce cost and improve productivity.
In particular, since the holding means 40 is composed of the support portions 43 and 44 having a concave-convex structure and a U-shaped notch, the formation thereof is particularly easy, the number of components is reduced, and the cost is further reduced. In addition, it is possible to reduce the number of times and improve the productivity.
[0031]
(Other)
Any function-enhancing device may be used as long as it has a plate-like insertion portion. In particular, the device mounting structure 10 properly prevents damage to any function. In the case where the memory card 100 is completely stored inside the electronic device like the memory card 100 described above, the function of preventing damage is not exhibited, but no problem occurs because damage is not caused in the first place. Further, even if the device mounting structure 10 is completely stored inside the electronic device like the memory card 100, it does not hinder the proper use of the device.
[0032]
In the above embodiment, the function expansion device is inserted between the separation body 20 and the fitting recess 30. However, a slit-shaped insertion port is provided on the upper surface of the separation body 20 and the inside of the separation body 20 is provided. The configuration may be such that the plate-shaped insertion portion of the function expansion device is stored in the device. However, in this case, it is necessary to provide the relay 20 with a relay connection terminal for connecting the connection terminal of the function expansion device and the main body connection terminal of the electronic device.
[0033]
The electronic device provided with the device mounting structure is not limited to a mobile phone, but may be any device using a function expansion device having a plate-shaped insertion portion. For example, a notebook personal computer, a mobile computer, a palmtop personal computer , PDA etc. may be used.
[0034]
【The invention's effect】
According to the first aspect of the present invention, since the separating body having the insertion opening of the function expansion device maintains the attached state in the fitting concave portion by the elastic force of the holding means, a load is externally applied to the function expansion device. Even in this case, the separating body is separated from the fitting concave portion by exceeding the elastic holding force of the holding means before an excessive load causing breakage, and the function expansion device is released from the added state of the load. Therefore, damage to the function expansion device is effectively avoided. In addition, since the above-mentioned effects are realized with a simple configuration of the separating body, the fitting recess and the holding means, and it is not necessary to enhance each configuration, unlike the conventional case, it is possible to avoid the cost increase and improve the productivity. It becomes possible to plan.
[0035]
According to the second aspect of the present invention, since the holding means is composed of the convex part and the concave part, the supporting part elastically supports one of the convex part and the concave part, it is possible to realize a simple configuration and further reduce the cost. At the same time, productivity can be improved.
[0036]
According to the third aspect of the present invention, since the concave portion and the convex portion are arranged at respective positions corresponding to the end portion which is far from the vicinity of the insertion opening of the separation body, the two portions are substantially orthogonal to the insertion direction of the function expansion device. The separation body can be rotated with respect to the load in the direction, and the function expansion device can be more effectively prevented from being damaged.
Further, since the fitting state between the convex portion and the concave portion that is near or far from the insertion port is maintained, it is possible to prevent the separation body from falling.
