Description

【０００１】
【発明の属する技術分野】
本発明は、折り畳み構造を有する携帯電話機やＰＤＡ（Personal Digital Assistants）等の外部接続端子を備えた携帯端末装置に関するものである。
【０００２】
【従来の技術】
近年、携帯電話機やＰＤＡ（Personal Digital Assistants）等の携帯端末装置は、携帯性を高めるために折り畳み機構を持ったものが普及しつつある。
【０００３】
例えば、図６に従来の携帯端末装置の一例を示すように、この携帯端末装置３１は携帯電話機に関するもので、ヒンジ部３４により開閉可能に連結された第１の筐体３２と第２の筐体３３とからなり、上記第１の筐体３２の内面側には液晶表示装置等の表示部３５とスピーカー部３６を備えるとともに、上記第２の筐体３３の内面側にはキー操作部３７とマイク部３９を備え、携帯端末装置３１を使用しない時には、図６に示すように折り畳んで小型化し、使用時にはヒンジ部３４を中心に第１の筐体３２を第２の筐体３３に対して回動させて開くことで使用するようになっていた。
【０００４】
また、第二の筐体３３の内面側にあるキー操作部３７は、その操作性を高めるためにキー３８を内面３３ａより若干突出させてあるが、折り畳みの際に第一の筐体３２と摺動して傷付く恐れがあるため、折り畳んだ際に第一の筐体３２と第二の筐体３３との間に、キー３８の突出量よりも大きな隙間Ｔを設けるようになっており、この隙間Ｔは第二の筐体３３の内面３３ａに形成された突起３３ｂが第一の筐体３２の内面３２ａに形成された窪み３２ｂに取着する弾性部材４０と当接させることによって形成するようになっていた。
【０００５】
また、第二の筐体３３の端部には通信用のＩ／Ｏコネクタや充電用のコネクタ等の外部接続端子４１が設けられており、ゴミやホコリ等の侵入を防止する必要があるため、使用しない時には弾性体からなるカバー部材４２によって覆うようになっており、このようなカバー部材４２としては、例えば図７に示すように、外部接続端子４１を塞ぐ蓋部４３と、この蓋部４３より延設された舌片部４４とからなり、舌片部４４の先端両側には抜け防止部４５を備え、筐体３３に形成されている二本のピン４６の間に上記カバー部材４２の舌片部先端を挿通させることにより取着してあり、カバー部材４２を開ける時には、蓋部４３に指や爪を引っ掛けて引き出すことにより外部接続端子４１を露出させるようになっていた。
【０００６】
【発明が解決しようとする課題】
しかしながら、図６に示す携帯端末装置３１のように、第二の筐体３３の内面３３ａに突起３３ｂを形成するとともに、第一の筐体３２の内面３２ａに弾性部材４０を設けたものでは、双方の筐体３２，３３に突起３３ｂと凹部３２ｂを形成しなければならず、各筐体３２，３３の構造が複雑化するとともに、各筐体３２，３３を製作するのに使用する金型も複雑になるために携帯端末装置３１が高価なものになってしまうといった課題があった。
【０００７】
また、近年、携帯端末装置３１の小型化に伴って部品の共通化を図り、部品点数の低減が要求されているが、第一の筐体３２と第二の筐体３３の隙間Ｔを規制する突起３３ｂ及び弾性部材４０とカバー部材４２は別々に製作されていたために部品点数を減らすことができないといった課題もあった。
【０００８】
さらに、図７に示すカバー部材４２を備えたものでは、舌片部４４をある程度長くする必要があり、それ故、蓋部４３を閉じた時には舌片部４４が第二の筐体３３内に大きく突出することになるため、筐体３３内に組み込む部品配置等が制約を受け、設計の自由度が損なわれるといった課題もあった。
【０００９】
その上、蓋部４３を引き出す際には摩擦係数の大きな舌片部４４とピン４６が摺動し、蓋部４３をスムーズに引き出すことが難しく、また、カバー部材４２は完全に固定された構造ではないため、蓋部４３をどこかに引っ掛けた状態で大きな力が加わると筐体３３から外れ、カバー部材４２を紛失してしまうといった恐れもあった。
【００１０】
【発明の目的】
本発明の目的は、簡単な構造でありながら外部接続端子のカバー部材を比較的スムーズに開くことができるとともに、部品点数を少なくすることができ、かつ携帯端末装置の折り畳み時に２つの筐体の間に隙間を設けてキーの傷付きを防止することが可能なカバー部材を備えた携帯端末装置を提供することにある。
【００１１】
【課題を解決するための手段】
そこで、本発明は上記課題に鑑み、２つの筐体を連結部によって折り畳み可能に連結してなり、いずれか一方の筐体にその内面より突出するキーを備えるとともに、少なくともいずれか一方の筐体に外部接続端子と、この外部接続端子を保護するカバー部材を具備する携帯端末装置において、上記カバー部材を、上記外部接続端子を覆う蓋部と、この蓋部より撓みを持って延設された舌片部と、この舌片部の先端に設けられた突起部とから構成し、上記カバー部材の突起部を上記一方の筐体内面に開口させた孔に挿通、突出させることにより上記カバー部材を上記一方の筐体に取着するとともに、上記一方の筐体内面より突出する突起部によって他方の筐体との間に隙間を設けるようにしたことを特徴とする。
【００１２】
また、カバー部材の舌片部は一対の弾性片とし、各弾性片には湾曲部を設けて撓ませるようにすることが好ましい。
【００１３】
さらに、上記外部接続端子は、筐体の連結部より離れた端部に配置するとともに、カバー部材の突起部を上記筐体端部近傍の内面より突出させるようにすることが好ましい。
【００１４】
【発明の実施の形態】
以下、本発明の実施形態について説明する。
【００１５】
図１は本発明の携帯端末装置の折り畳んだ時の状態を示す断面図、図２は図１のＡ部を拡大した断面図、図３は図１のＡ部に備えるカバー部材を閉じた時の状態を示す斜視図、図４は図１のＡ部に備えるカバー部材を開いた時の状態を示す斜視図、図５は本発明の携帯端末装置に備えるカバー部材を示す斜視図である。
【００１６】
この携帯端末装置１は携帯電話機に関するもので、ヒンジ部４により開閉可能に連結する第１の筐体２と第２の筐体３とからなり、上記第１の筐体２の内面２ａ側には液晶表示装置等の表示部５とスピーカー部６を備えるとともに、上記第２の筐体３の内面３ａ側にはキー操作部７とマイク部９を備え、携帯端末装置１を使用しない時には図１に示すように折り畳んで小型化し、携帯し易くするとともに、使用時にはヒンジ部４を中心に第一の筐体２を第二の筐体３に対して回動させて開くことで、電話をかけたり、情報の入力や情報の読み出し／読み込み等を行うようになっている。
【００１７】
また、第二の筐体３内には、無線送受信部や制御部等を含む回路基板１０、電池１１、通信用Ｉ／Ｏコネクタとしての外部接続端子１２をそれぞれ内蔵してあり、外部接続端子１２は第二の筐体３のヒンジ部４と反対側の端部に配置してある。また、外部接続端子１２にはゴミやホコリが侵入することを防止するためにカバー部材１３を設けてあり、このカバー部材１３は、図５に示すように、外部接続端子１２を覆う蓋部１４と、この蓋部１４の一方の主面に対して略直角に撓みを持って延設される舌片部１５と、この舌片部１５の先端に略直角に設けられた突起部１６とからなり、ゴムや弾性を有する樹脂等の弾性体により一体的に形成してある。
【００１８】
また、舌片部１５は一対の弾性片１７からなり、各弾性片１７は湾曲部１７ａを設けることによって撓みを持たせてあり、突起部１６側を固定した状態で蓋部１４を図５の矢印の方向に引っ張ると、弾性片１７の湾曲部１７ａが変形して弾性片１７の長さを可変し得るようになっている。なお、ここで、撓みを持って延設された舌片部１５とは、図５に示す構造だけに限定されるものではなく、引っ張った際に舌片部１５の長さを可変し得るように構成されていれば構わない。
【００１９】
そして、図２に示すように、第二の筐体３の内面３ａに開口させてある孔３ｃに上記カバー部材１３の突起部１６を挿通、突出させることによりカバー部材１３を筐体３に取着するとともに、内面３ａより突出させた突起部１６に第一の筐体２との隙間を規制するストッパとしての機能を持たせてある。なお、突起部先端１８ａから内面３ａまでの突出量Ｖは、キー頂面８ａから内面３ａまでの突出量Ｗよりも大きくしてある。また、カバー部材１３の舌片部１５は回路基板１０上に配置してある。
【００２０】
その為、第一の筐体２を第二の筐体３に対して折り畳んだ時、第一の筐体２を第二の筐体３の内面３ａより突出させた突起部１６で支持し、第一の筐体２と第二の筐体３との間に、キー８の突出量Ｗよりも大きな隙間を形成することができるため、キー頂面８ａが第一の筐体２と摺動することによって傷付くことを防止することができる。
【００２１】
また、第一の筐体２と第二の筐体３の隙間を規制する突起部１６はカバー部材１３に一体的に形成してあるため、部品の共通化を図ることができ、部品点数を低減することができる。
【００２２】
しかも、突起部１６は弾性体からなるため、従来のような突起との接触に伴う傷付き防止用の弾性部材が不要で、突起部１６と当接する第一の筐体２の内面２ａには何ら加工を施す必要がないため、第一の筐体２の構造を簡単にすることができるとともに、筐体２を製作するのに用いる金型構造も簡単になるため、結果として携帯端末装置１を安価に製作することができる。
【００２３】
さらに、本実施形態では、外部接続端子１２を第二の筐体３のヒンジ部４と反対側の端部に配置するとともに、外部接続端子１２を覆うカバー部材１３の突起部１６も第二の筐体３のヒンジ部４と反対側の端部内面３ａに突出させてあることから、携帯端末装置１を折り畳んだ時には、キー操作部７の両端に配置されたヒンジ部４と突起部１６とで第一の筐体２を支持することができるとともに、第一の筐体２に押圧力が作用したとしてもキー８と接触することを効果的に防止することができる。
【００２４】
また、外部接続端子１２を使用する場合、カバー部材１３の蓋部１４に爪や指等を引っ掛けて持ち上げることにより蓋部１４を開けるのであるが、この時、蓋部１４は筐体３より引き出した後、持ち上げることができるため、蓋部１４をスムーズに開くことができる。
【００２５】
即ち、本発明のカバー部材１３には、撓みを持たせた舌片部１５を有することから、蓋部１４を開ける際、舌片部１５の湾曲部１７ａが変形して伸びるため、蓋部１４を筐体３よりスムーズに引き出すことができるとともに、舌片部１５は厚みがそれ程厚くなく変形し易いため、蓋部１４を容易に持ち上げることができる。
【００２６】
その為、従来のカバー部材のように舌片部とピンとが大きな摩擦をもって摺動するようなことがなく、蓋部１４を容易に開けることができる。
【００２７】
また、本発明のカバー部材１３の舌片部１５は、湾曲部１７ａを設けて撓みを持たせてあるため、舌片部１５の長さを図７に示す従来のカバー部材と比較して短くすることができるため、筐体３内への張り出しが小さく、それ故、筐体３に組み込む部品配置等が制約を受け難いため、設計の自由度を高めることもできる。
【００２８】
以上、本発明の実施形態について示したが、本発明はこれらの実施形態だけに限定されるものではなく、例えば、外部接続端子１２とそのカバー部材１３を第二の筐体３の端部以外に側面に配置したり、あるいは外部接続端子１２とそのカバー部材１３を第一の筐体２側に配置するようにしても構わない。
【００２９】
また、本発明の実施形態ではヒンジ部４を用いて折り畳み可能に構成した携帯端末装置１について示したが、他の連結部によって折り畳み可能に構成したものにも適用することができる。
【００３０】
さらに、本実施形態では携帯電話機を基に説明したが、折り畳み構造を有するＰＤＡ（Personal Digital Assistants）等の外部接続端子を有する携帯端末装置にも適用することができる。
【００３１】
このように、本発明の要旨を逸脱しない範囲で改良や変更したものにも適用することができることは言う迄もない。
【００３２】
【発明の効果】
以上のように、本発明によれば、２つの筐体を連結部によって折り畳み可能に連結してなり、いずれか一方の筐体にその内面より突出するキーを備えるとともに、少なくともいずれか一方の筐体に外部接続端子と、該外部接続端子を保護するカバー部材を具備する携帯端末装置において、上記カバー部材を、上記外部接続端子を覆う蓋部と、この蓋部より撓みを持って延設された舌片部と、この舌片部の先端に設けられた突起部とから構成し、上記カバー部材の突起部を上記一方の筐体内面に開口させた孔に挿通、突出させることにより上記カバー部材を取着するとともに、上記一方の筐体内面より突出する突起部によって他方の筐体との間に隙間を設けるようにしたことによって、折り畳んだ際に一方の筐体内面より突出するキー頂面が他方の筐体と接触して傷付くことを防止することができるとともに、外部接続端子のカバー部材に２つの筐体の隙間を規制するストッパー機能を持たせたことから部品点数を低減することができる。
【００３３】
また、カバー部材の突起部を弾性体により形成することで、従来のような突起との接触に伴う傷付き防止用の弾性部材が不要となり、突起部と当接する筐体内面に何ら加工を施す必要がないため、筐体の構造を簡単にすることができるとともに、筐体を製作するのに用いる金型構造も簡単になるため、結果として携帯端末装置を安価に製作することができる。
【００３４】
さらに、外部接続端子を使用する場合、カバー部材の蓋部に爪や指等を引っ掛け、スムーズに持ち上げることができるため、取り扱いが容易で、特にカバー部材の舌片部を一対の弾性片から構成するとともに、各弾性片に湾曲部を設けて撓みを持たせることにより蓋部の開閉をよりスムーズに行うことができ好ましい。
【００３５】
また、カバー部材を備える筐体内への張り出しを小さくすることができるため、筐体に組み込む部品配置等が制約を受け難く、設計の自由度を高めることもできる。
【００３６】
さらに、本発明によれば、外部接続端子を、連結部より離れた筐体端部に配置するとともに、カバー部材の突起部を上記筐体端部近傍の内面より突出させることにより、折り畳んだ状態において一方の筐体に押圧力が作用したとしても連結部と突起部によって支持し、キーが対向する筐体と接触して傷付くことを効果的に防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a mobile terminal device having an external connection terminal such as a mobile phone having a folding structure or a PDA (Personal Digital Assistants).
[0002]
[Prior art]
In recent years, portable terminal devices such as mobile phones and PDAs (Personal Digital Assistants) that have a folding mechanism in order to improve portability are becoming widespread.
[0003]
For example, as shown in FIG. 6 as an example of a conventional mobile terminal device, the mobile terminal device 31 relates to a mobile phone, and includes a first casing 32 and a second casing that are connected by a hinge portion 34 so as to be opened and closed. And a display unit 35 such as a liquid crystal display device and a speaker unit 36 on the inner surface side of the first casing 32, and a key operation unit 37 on the inner surface side of the second casing 33. When the portable terminal device 31 is not used, it is folded and miniaturized as shown in FIG. 6, and when used, the first housing 32 is centered on the hinge portion 34 with respect to the second housing 33. It was designed to be used by rotating and opening.
[0004]
The key operation unit 37 on the inner surface side of the second housing 33 has a key 38 slightly protruded from the inner surface 33a in order to improve the operability. Since there is a risk of sliding and scratching, a gap T larger than the protruding amount of the key 38 is provided between the first casing 32 and the second casing 33 when folded. The gap T is formed by bringing the projection 33b formed on the inner surface 33a of the second housing 33 into contact with the elastic member 40 attached to the recess 32b formed on the inner surface 32a of the first housing 32. I was supposed to.
[0005]
In addition, an external connection terminal 41 such as a communication I / O connector or a charging connector is provided at the end of the second housing 33, and it is necessary to prevent intrusion of dust or dust. When not in use, the cover member 42 is made of an elastic body, and as such a cover member 42, for example, as shown in FIG. 7, a lid portion 43 for closing the external connection terminal 41, and this lid portion 43, a tongue piece portion 44 extending from 43, and provided with a slip-off preventing portion 45 on both sides of the tip of the tongue piece portion 44, and between the two pins 46 formed on the housing 33. In order to open the cover member 42, when the cover member 42 is opened, the external connection terminal 41 is exposed by hooking a finger or a nail to the lid portion 43 and pulling it out.
[0006]
[Problems to be solved by the invention]
However, as in the portable terminal device 31 shown in FIG. 6, the protrusion 33 b is formed on the inner surface 33 a of the second housing 33 and the elastic member 40 is provided on the inner surface 32 a of the first housing 32. The projections 33b and the recesses 32b must be formed on both the casings 32 and 33, the structure of the casings 32 and 33 is complicated, and the mold used to manufacture the casings 32 and 33 is used. There is a problem that the mobile terminal device 31 becomes expensive due to the complexity.
[0007]
In recent years, with the miniaturization of the mobile terminal device 31, parts have been made common and reduction in the number of parts has been demanded, but the gap T between the first casing 32 and the second casing 33 is regulated. Since the protrusion 33b and the elastic member 40 and the cover member 42 are manufactured separately, there is a problem that the number of parts cannot be reduced.
[0008]
Furthermore, in the thing provided with the cover member 42 shown in FIG. 7, it is necessary to lengthen the tongue piece portion 44 to some extent. Therefore, when the lid portion 43 is closed, the tongue piece portion 44 is placed in the second housing 33. Since it protrudes greatly, the arrangement | positioning etc. of components incorporated in the housing | casing 33 are restricted, and the subject that the freedom degree of design was impaired also occurred.
[0009]
In addition, when the lid portion 43 is pulled out, the tongue piece portion 44 and the pin 46 having a large friction coefficient slide so that it is difficult to pull out the lid portion 43 smoothly, and the cover member 42 is completely fixed. Therefore, if a large force is applied in a state where the lid portion 43 is hooked somewhere, there is a possibility that the cover member 42 may be lost due to detachment from the housing 33.
[0010]
OBJECT OF THE INVENTION
An object of the present invention is to enable the cover member of the external connection terminal to be opened relatively smoothly while having a simple structure, to reduce the number of parts, and for the two housings to be folded when the portable terminal device is folded. An object of the present invention is to provide a portable terminal device including a cover member that can be provided with a gap therebetween to prevent a key from being damaged.
[0011]
[Means for Solving the Problems]
Accordingly, in view of the above problems, the present invention has two casings connected to each other so as to be foldable by a connecting portion, and includes a key protruding from the inner surface of at least one of the casings. In the portable terminal device comprising an external connection terminal and a cover member that protects the external connection terminal, the cover member is extended from the lid with a cover that covers the external connection terminal, with a deflection. The cover member comprises a tongue piece and a protrusion provided at the tip of the tongue piece, and the protrusion of the cover member is inserted and protruded through a hole opened in the inner surface of the one casing. Is attached to the one casing, and a gap is provided between the casing and the other casing by a projection protruding from the inner surface of the one casing.
[0012]
Moreover, it is preferable that the tongue piece portion of the cover member is a pair of elastic pieces, and each elastic piece is provided with a bending portion to be bent.
[0013]
Furthermore, it is preferable that the external connection terminal is disposed at an end portion away from the connecting portion of the housing, and the protruding portion of the cover member is protruded from the inner surface in the vicinity of the housing end portion.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described.
[0015]
1 is a cross-sectional view showing a folded state of the mobile terminal device of the present invention, FIG. 2 is an enlarged cross-sectional view of a portion A in FIG. 1, and FIG. 3 is a view when a cover member provided in the portion A of FIG. FIG. 4 is a perspective view showing a state when the cover member provided in part A of FIG. 1 is opened, and FIG. 5 is a perspective view showing the cover member provided in the portable terminal device of the present invention.
[0016]
The mobile terminal device 1 relates to a mobile phone, and includes a first casing 2 and a second casing 3 that are connected to each other by a hinge portion 4 so as to be opened and closed, and on the inner surface 2a side of the first casing 2. Includes a display unit 5 such as a liquid crystal display device and a speaker unit 6, and also includes a key operation unit 7 and a microphone unit 9 on the inner surface 3 a side of the second housing 3, and is illustrated when the portable terminal device 1 is not used. As shown in FIG. 1, the phone can be folded and downsized to facilitate carrying, and in use, the first housing 2 can be rotated with respect to the second housing 3 around the hinge 4 to open the phone. The information is input, the information is input, and the information is read / read.
[0017]
Further, the second housing 3 incorporates a circuit board 10 including a wireless transmission / reception unit and a control unit, a battery 11, and an external connection terminal 12 as a communication I / O connector. 12 is arranged at the end of the second housing 3 opposite to the hinge 4. Further, a cover member 13 is provided in the external connection terminal 12 in order to prevent dust and dust from entering, and the cover member 13 is a lid portion 14 that covers the external connection terminal 12 as shown in FIG. And a tongue piece 15 extending with a substantially right angle with respect to one main surface of the lid portion 14, and a protrusion 16 provided at a substantially right angle at the tip of the tongue piece 15. It is integrally formed of an elastic body such as rubber or elastic resin.
[0018]
Further, the tongue piece portion 15 is composed of a pair of elastic pieces 17, and each elastic piece 17 is bent by providing a curved portion 17a, and the lid portion 14 is fixed in a state where the projection portion 16 side is fixed. When pulled in the direction of the arrow, the curved portion 17a of the elastic piece 17 is deformed so that the length of the elastic piece 17 can be varied. Here, the tongue piece portion 15 extended with bending is not limited to the structure shown in FIG. 5, and the length of the tongue piece portion 15 can be varied when pulled. It does not matter as long as it is configured.
[0019]
Then, as shown in FIG. 2, the cover member 13 is attached to the housing 3 by inserting and projecting the protruding portion 16 of the cover member 13 into the hole 3c opened in the inner surface 3a of the second housing 3. At the same time, the protrusion 16 projecting from the inner surface 3a is provided with a function as a stopper for regulating the gap with the first housing 2. The protruding amount V from the protrusion tip 18a to the inner surface 3a is larger than the protruding amount W from the key top surface 8a to the inner surface 3a. Further, the tongue piece 15 of the cover member 13 is disposed on the circuit board 10.
[0020]
Therefore, when the first housing 2 is folded with respect to the second housing 3, the first housing 2 is supported by the protrusions 16 protruding from the inner surface 3 a of the second housing 3, Since a gap larger than the protrusion amount W of the key 8 can be formed between the first casing 2 and the second casing 3, the key top surface 8a slides on the first casing 2. By doing so, it can be prevented from being damaged.
[0021]
In addition, since the protrusion 16 that regulates the gap between the first housing 2 and the second housing 3 is formed integrally with the cover member 13, the parts can be shared, and the number of parts can be reduced. Can be reduced.
[0022]
In addition, since the protrusion 16 is made of an elastic body, there is no need for an elastic member for preventing damage caused by contact with the protrusion as in the prior art, and the inner surface 2a of the first housing 2 that contacts the protrusion 16 is not formed. Since no processing is required, the structure of the first casing 2 can be simplified, and the mold structure used to manufacture the casing 2 is also simplified. As a result, the mobile terminal device 1 Can be manufactured at low cost.
[0023]
Further, in the present embodiment, the external connection terminal 12 is arranged at the end opposite to the hinge portion 4 of the second housing 3, and the projection 16 of the cover member 13 covering the external connection terminal 12 is also the second. Since it protrudes from the end portion inner surface 3 a opposite to the hinge portion 4 of the housing 3, when the mobile terminal device 1 is folded, the hinge portions 4 and the projection portions 16 disposed at both ends of the key operation portion 7 Thus, the first housing 2 can be supported, and even when a pressing force is applied to the first housing 2, it can be effectively prevented from contacting the key 8.
[0024]
When the external connection terminal 12 is used, the lid 14 is opened by hooking a nail or a finger on the lid 14 of the cover member 13 and lifting it. At this time, the lid 14 is pulled out from the housing 3. Then, the lid 14 can be opened smoothly.
[0025]
That is, since the cover member 13 of the present invention has the tongue piece portion 15 which is bent, when the lid portion 14 is opened, the curved portion 17a of the tongue piece portion 15 is deformed and extended, so that the lid portion 14 Can be pulled out more smoothly than the casing 3 and the tongue piece 15 is not so thick and easily deformed, so that the lid 14 can be easily lifted.
[0026]
Therefore, the tongue 14 and the pin do not slide with great friction unlike the conventional cover member, and the lid 14 can be easily opened.
[0027]
Further, since the tongue piece portion 15 of the cover member 13 of the present invention is provided with a bending portion 17a to bend, the length of the tongue piece portion 15 is shorter than that of the conventional cover member shown in FIG. Therefore, the projecting into the housing 3 is small, and therefore, the arrangement of components incorporated in the housing 3 is not easily restricted, so that the degree of freedom in design can be increased.
[0028]
As mentioned above, although embodiment of this invention was shown, this invention is not limited only to these embodiment, For example, external connection terminal 12 and its cover member 13 are other than the edge part of the 2nd housing | casing 3. Alternatively, the external connection terminal 12 and its cover member 13 may be disposed on the first housing 2 side.
[0029]
In the embodiment of the present invention, the portable terminal device 1 configured to be foldable using the hinge portion 4 has been described. However, the portable terminal device 1 can be applied to those configured to be foldable by other connecting portions.
[0030]
Furthermore, although the present embodiment has been described based on a mobile phone, it can also be applied to a mobile terminal device having an external connection terminal such as a PDA (Personal Digital Assistants) having a folding structure.
[0031]
In this way, it goes without saying that the present invention can also be applied to improvements and changes made without departing from the scope of the present invention.

【The invention's effect】
As described above, according to the present invention, two casings are connected to each other so as to be foldable by a connecting portion, and one of the casings is provided with a key protruding from the inner surface, and at least one of the casings is provided. In a portable terminal device having an external connection terminal on the body and a cover member protecting the external connection terminal, the cover member is extended with a lid portion covering the external connection terminal and a deflection from the lid portion. The cover member by inserting and projecting the protrusion of the cover member into the hole opened in the inner surface of the one casing. By attaching a member and providing a gap with the other housing by the projection protruding from the inner surface of the one housing, the top of the key that protrudes from the inner surface of the one housing when folded. Other side Can be prevented from coming into contact with the casing of the housing, and the cover member of the external connection terminal has a stopper function for regulating the gap between the two casings, thereby reducing the number of parts. .
[0033]
In addition, by forming the protrusion of the cover member with an elastic body, a conventional elastic member for preventing damage due to contact with the protrusion becomes unnecessary, and the inner surface of the casing that contacts the protrusion is processed. Since it is not necessary, the structure of the housing can be simplified, and the mold structure used to manufacture the housing is also simplified. As a result, the portable terminal device can be manufactured at low cost.
[0034]
In addition, when using an external connection terminal, it is easy to handle because it can be easily lifted by hooking a nail or finger on the lid of the cover member, and the tongue piece of the cover member is composed of a pair of elastic pieces. In addition, it is preferable that each elastic piece is provided with a bending portion to bend and thereby the lid portion can be opened and closed more smoothly.
[0035]
In addition, since the overhang into the housing including the cover member can be reduced, the arrangement of components incorporated in the housing is not easily restricted, and the degree of design freedom can be increased.
[0036]
Further, according to the present invention, the external connection terminal is disposed at the end of the casing that is away from the coupling portion, and the cover member is folded by protruding the protrusion from the inner surface near the end of the casing. In this case, even if a pressing force is applied to one of the casings, it can be supported by the connecting portion and the protruding portion, and the key can be effectively prevented from coming into contact with the opposing casing and being damaged.
