Description

【０００１】
【発明の属する技術分野】
本発明はパック化された電池等を着脱可能な電子機器に関し、特に長尺のパック体を必要とする電子機器に有効である。
【０００２】
【従来の技術】
現在、電池やＨＤＤ等は夫々パック化されパソコン等の電子機器本体に着脱可能とすることにより電子機器の性能をレベルアップさせることが可能となっている（例えば、実開平６−２４３１号公報参照）。
【０００３】
また、この種パック化された電池等（以下、パック体と称す。）の着脱構成としては、例えば特開平８−１６２７８号公報、特開平９−６４６６号公報等において種々提案されている。
【０００４】
【発明が解決しようとする課題】
上記従来提案が対象とするパック体の大きさは、手のひらサイズ程度の大きさであり、その着脱操作は片手で行なえることを主眼としていたため、片手で装着を解除し、他の手でパック体を支えることができた。従って、電子機器の裏面を下方に向けた状態で、上記機器の裏面側からパック体を着脱することも簡単に行なえた。
【０００５】
しかし、携帯型の電子機器における長時間連続使用の要求に沿って電池パックを大型化した場合、パック体を電子機器本体に確実に装着固定（ロック）するためには複数のロック手段が必要となる。これら複数のロック手段を片手で解除可能とすると、上記ロック手段同士を連動させるための機構が必要となり、電子機器が大型化し携帯性を損なうこととなる。一方、例えば２つのロック手段を別々の手で操作する構成では、パック体自身を支える手がなくなるため、電子機器の裏面を下方に向けた状態で、上記機器の裏面側に装着されたパック体の着脱は困難となる。特に、パック体が長尺化して手のひらを広げた長さよりもロック手段同士の離間距離が長くなる構成ではこの問題が顕著となる。
【０００６】
【課題を解決するための手段】
本発明は、上記課題に鑑みてなされたもので、その特徴は、パック体を本体収納部に対して第１の方向より挿入した後上記第１方向と直交する第２の方向にスライドさせることにより上記収納部に装着可能とするパック体を着脱可能な電子機器であって、上記本体は、上記収納部の上記第１、第２の方向に直交しない一対の側壁の夫々に形成され、上記第２方向と平行に延在する固定突起と、該固定突起に隣接して配され、上記第２方向と直交する２方向にスライド可能に上記一対の側壁の夫々に配された可動突起と、該可動突起の夫々に上記収納部内に向かう第１付勢力と上記第１方向と反対方向へ向かう第２付勢力とを付与する付勢手段と、該付勢手段の上記第１付勢力に抗して、かつ上記第２付勢力を利用して上記可動突起を略上記固定突起の延在線上に保持する手段と、上記可動突起を上記付勢手段の第２付勢力に抗して上記第１方向側へ操作するための操作手段とを備え、上記パック体は、上記収納部への装着状態において、上記一対の側壁に夫々対向する一対の面に夫々形成された溝を有し、該溝は夫々、パック体を収納部に上記第１方向に挿入する際にその挿入方向端部が開放すると共に上記固定及び可動突起を嵌合可能に上記開放端より上記第１方向と反対方向に延在する第１溝部と、第１溝部の最深部より上記第２方向の反対方向に延在する第２溝部と、上記第１溝部の最深部より更に上記第２方向の反対方向に延在し、かつ上記可動突起を嵌合可能な第３溝部とを備え、更に上記第１溝部には該第１溝部に嵌合された上記可動突起の上記第１方向及びその反対方向へのスライドに応答して上記保持手段による保持を解除するために上記付勢手段の第１付勢力に抗する方向にスライドさせる手段が形成されていることにある。
【０００７】
【発明の実施の形態】
図１は本発明を適用してなる電子機器の一実施例の要部を示す要部斜視図、図２〜図５は図１のＡ−Ａ’線断面図、図６〜図８は図１のＢ−Ｂ’線断面図であり、以下では上記図１〜図８に基づいて本実施例を説明する。
【０００８】
本実施例の電子機器本体１の背面には、底面及び背面側が開放され、空間形状が長方体状の収納部２が形成されている。この収納部２には、この収納部２の空間形状と略一致する形状を有する例えば電池及び／若しくは電子部品等を内蔵したパック体３を収納する。
【０００９】
上記収納部２の対向する一対の側壁４、５には、互いに対向する位置に第１の係止突起６が植設されると共に、該第１係止突起６に本体１前面側に隣接して上下方向に延在する開口７（７’）が穿設されている。この開口７を介してな第２係止突起８（８’）の一端が収納部２内に突出可能であると共に、上記第２係止突起８（８’）の上記一端は上記開口７（７’）の延在方向に摺動可能となっている。
【００１０】
上記第１係止突起６は、本体１の前後方向に延在する長方体状の突起であり、また、上記第２係止突起８（８’）は後述する付勢機構によりその一端が収納部に突出し、かつ上記第１係止突起６より下方に位置するように常時付勢されている。
【００１１】
尚、収納部２の一方の側壁５に植設された第１係止突起については、図面上に明示されていないが、開口及び第２係止突起と同様に側壁４に形成されたものに対向して側壁５に形成されている。また、以下では、説明の都合上、上記第１、第２係止突起６、８（８’）の本体１前後方向の長さを単に長さと称し、上下方向の長さを厚みと称し、更に第１係止突起６の水平方向の長さ（側壁４からの高さ）を高さと称する。
【００１２】
パック体３が収納部２に収納された際に上記側壁４、５と夫々対向する側面９、１０には、上記第１、第２係止突起６、８（８’）と係合する係止溝１１（１１’）が形成されている。
【００１３】
上記係止溝１１（１１’）は、上端が開放すると共に、上記第１、第２係止突起６、８（８’）が図１に示す如くその長さ方向に略直線状に並列された状態で、上記第１、第２係止突起６、８（８’）を共に嵌合可能な幅を有した平面形状が略長方形の基部溝１２、（１２’）と、この基部溝１２、（１２’）の最深部より背面方向に延在する第１規制溝１３、（１３’）と、この基部溝１２、（１２’）の底部より更に下方に延在する第２規制溝１４（１４’）とからなる。
【００１４】
上記第２規制溝１４（１４’）の基部溝１２、（１２’）との連通部分の幅は、第２係止突起８（８’）の長さより若干大とし、上記第２係止突起８（８’）を上記第２規制溝１４（１４’）に嵌合可能としている。また、上記第１規制溝１３、（１３’）の上下方向の幅は上記第１係止突起６の厚みより若干大とし、上記第１係止突起６を上記第１規制溝１３（１３’）に嵌合可能としている。更に、上記第１規制溝１３、（１３’）の最深部から上記第２規制溝１４（１４’）の本体１前面側端部までの水平距離を、上記第１係止突起６の本体１背面側端部から上記第２係止突起８（８’）の本体１前面側端部までの水平距離に一致させている。これにより、後述の説明からも明らかとなるように、第１、第２規制溝１３（１３’）、１４（１４’）に夫々第１、第２係止突起６、８（８’）が同時に嵌合した状態となることを可能とする（図２参照）。
【００１５】
上記基部溝１２（１２’）の本体１前面側上端には、パック体２の着脱時に上記第2係止突起８（８’）の一端を後述する付勢機構の付勢力に抗して本体１内方に押込むための部位（以下では、押込部位と称す。）１５（１５’）が形成されている。この押込部位１５（１５’）は、その表面高さが、基部溝１２（１２’）開放端側から基部溝１２（１２’）最深部方向に溝１１（１１’）底面に対して徐々に高くなり、その後溝１１（１１’）底面と同等の高さまで徐々に低くなる断面略アーチ状をなしている。
【００１６】
次に図２〜図５を用いて、収納部２へのパック体３の着脱を説明する。尚、図２〜図５は、図１のＡ−Ａ’線断面図であるため、収納部２の側壁４側しか示していないが、上述の説明からも明らかなように、側壁５側においても同様な状況となっていることは説明するまでもない。また、図２〜図５においてはパック体３を破線により透過的に示している。
【００１７】
図２は、収納部２にパック体３が装着された状態を示し、この状態では、第１、第２係止突起６、８は夫々第１、第２規制溝１３、１４に嵌合している。このため、パック体３の本体１背面及び底面方向への移動が規制される。
【００１８】
図２に示した状態から、後述する操作釦を押下して第２係止突起８を図３に示す如く第１係止突起６と略一直線上に整列される位置までスライドさせると、第２係止突起８の第２規制溝１４への嵌合が解除されるため、パック体３の本体１背面方向へのスライドが可能となる。
【００１９】
そこで、図４に示す如く、パック体３を本体１背面方向にスライドさせて第１、第２係止突起１３、１４が基部溝１２の開放上端直下に位置するまで移動させる。これにより、第１係止突起６の第１規制溝１３への嵌合が解除されるため、パック体３の本体１底面方向へのスライドが可能となり、図５に示す如く、パック体３を収納部２から完全に取り外すことができる。また、この時、第２係止突起１４は、上記パック体３のスライド時に押込部位１５が作用して図２に示した位置に復帰する。尚、この作用は、後述する付勢機構の説明において詳細に説明する。
【００２０】
一方、パック体３を収納部２に装着する手順は、上記取外手順と逆順でり、まずパック体３の基部溝１２に第１、第２係止突起６、８を嵌合すべく上記基部溝１２の開放端と第１、第２係止突起６、８との位置を合せてパック体３を収納部２の底面側より挿入する。このとき、第２係止突起８の下端は上記基部溝の１２の下端と当接して以後は、上記パック体３の挿入力によって付勢機構の付勢力に抗して上方にスライドされ、図４に示す如く、略第１係止突起６の水平レベル位置まで持ち上げられる。従って、この状態から、パック体３を本体１前面方向にスライドさせることにより、図３に示す如く、第１係止突起６は第１規制溝１３に嵌合すると共に第２係止突起８は第２規制溝１４直上に位置することとなる。その後、第２係止突起８を第２規制溝１４に嵌合させることにより装着が完了する。
【００２１】
図６〜図８は、上述した第２係止突起８、８’の付勢機構２０、２０’を説明するためのものであり、この付勢機構２０、２０’は夫々開口７、７’により収納部２に連通した本体１内に配されている。
【００２２】
上記付勢機構２０、２０’は夫々、本体１底面側より上方向にスライド操作可能でかつ図中左右方向にも僅かにスライド可能に本体１底面側に装着された操作釦２１、２１’と、該操作釦２１、２１’の上面（下面は操作面となる。）夫々に収納部２側より順に植設された第１〜第３の垂設部２２、２２’、２３、２３’、２４、２４’と、上記第１垂設部２２、２２’に巻回されると共に一端が本体１に固定され他端が第２垂設部２３、２３’に固定されたコイルスプリングからなる付勢手段２５、２５’とを備える。
【００２３】
上記付勢手段２５、２５’は、その両端が上述のように固定されているため、操作釦２１、２１’を常時本体１底面方向及び収納部２方向へ付勢する。また、第２垂設部２３、２３’の先端には上記第２係止突起８、８’が一体的に装着されている。更に、上記第３垂設部２４、２４’の先端は収納部２方向に折曲されて係止端部を形成すると共に、開口７、７’近傍の本体１内壁に一体的に、図６に示す如く第２係止突起８、８’が開口７、７’上端に位置（この位置は、図３に示す如く第１係止突起６と略水平となる位置）に位置したとき、上記第３垂設部２４、２４’の係止端部を頂部に係止するためのＬ字状の係止部２６、２６’が形成されている。また、上記係止部２６、２６’の上記第３垂設部２４、２４’と対向する頂部近傍は若干盛り上がると共にその盛上部分の下端にはテーパが施されている。
【００２４】
次に上記付勢機構２０、２０’の動作を説明する。
【００２５】
図８は、図２に示す如くパック体３を収納部２に完全に装着した場合に、第２係止突起８、８’が夫々第２規制溝１４、１４’に嵌合している状態と同一の状態である。このとき、付勢手段２５、２５’の付勢力により、第３垂設部２４、２４’の先端の収納部２方向に折曲された係止端部は上記係止部２６、２６’の盛上部分の下方において第３垂設部２４、２４’に当接する如く位置すると共に、操作釦２１、２１’は本体１底面方向に付勢されている。
【００２６】
この状態において、操作釦２１、２１’を付勢手段２５、２５’の付勢力に抗して本体１上面方向に押圧操作すると、図６に示す如く、第３垂設部２４、２４’の係止端部は、上記係止部２６、２６’の上記テーパに沿って上方に押し上げられ、上記係止部２６、２６’の上方まで押し上げることが可能である。この押上状態では、第３垂設部２４、２４’の係止端部の上記係止部２６、２６’への当接が解除されると共に、付勢手段２５、２５’の収納部２方向への付勢力により、図６に示す如く、第３垂設部２４、２４’の係止端部が係止部２６、２６’の頂部に係止される。この係止状態は、図３及び図４に示した如く、第２係止突起８、８’が第１係止突起６と一直線上に整列された状態である。
【００２７】
この第３垂設部２４、２４’の係止端部と係止部２６、２６’の頂部との係止は、パック体３を収納部２に着脱することにより解除される。
【００２８】
具体的には、例えば図４に示す状態からパック体３を取り外すために図５に示す状態までパック体３をスライドさせると、そのスライド時押込部位１５、１５’が第２係止突起８、８’に作用し、付勢手段２５、２５’の付勢力に抗して第２係止突起８、８’を本体１内方に押込む。この押込み状態では、第３垂設部２４、２４’の係止端部は係止部２６、２６’の頂部から離間し、第３垂設部２４、２４’の係止端部と係止部２６、２６’の頂部との係止は解除され、かつ、付勢手段２５、２５’の付勢力により、図７に示す如く、第３垂設部２４、２４’の係止端部は上記係止部２６、２６’の盛上部分の下方に付勢され、最終的に図５に示した如くパック体３が収納部２より完全に取り外された際には、図８に示す状態に復帰する。
【００２９】
尚、付勢機構２０、２０’が図８に示す状態にあるときに、パック体３を収納部２へ装着する際、上述した如く、パック体３の挿入力によって付勢手段２５、２５’の付勢力に抗して第２係止突起８、８’は略第１係止突起６、６’の水平レベル位置まで持ち上げられるが、この位置は図７に示す如く第３垂設部２４、２４’の係止端部と係止部２６、２６’の頂部との係止が行なえない程度までとなる様に各部は設計されており、パック体３の収納部２への挿入時に図６に示す如き第３垂設部２４、２４’の係止端部と係止部２６、２６’の頂部との係止が行なわれることはない。
【００３０】
また、本実施例では、パック体３を収納部２へ装着する際に、付勢機構２０、２０’が図６に示すように第３垂設部２４、２４’の係止端部と係止部２６、２６’の頂部とが係止された状態にあったとしても、問題なくパック体３を装着できる。
【００３１】
即ち、付勢機構２０、２０’が図６に示す状態のときに、パック体３を収納部２に挿入すると、上述したパック体３の取外しと同様に、押込部位１５、１５’が第２係止突起８、８’に作用し、付勢手段２５、２５’の付勢力に抗して第２係止突起８、８’を本体１内方に押込み、第３垂設部２４、２４’の係止端部を係止部２６、２６’の頂部から離間せしめる。この結果、第２係止突起８、８’は付勢手段２５、２５’の付勢力により本体１底面側に付勢される。従って、上述の図８の状態と同様な状態となり、同様に装着が可能となる。
【００３２】
上記説明においては、パック体３の取外し時、あたかも操作釦２１、２１’を同時に操作するように説明しているが、構成上同時に操作する必要性がないことは説明するまでもなく、従って、上記パック体３を片手で支えながら、他の手で操作釦２１、２１’を順に操作することができる。
【００３３】
尚、本実施例では、収納部２を本体１背面底面側に設けた場合について説明したが、本発明はこれに限定されるものではなく、本体１のいずれの面に収納部を形成しても良いことは説明するまでもない。
【００３４】
【発明の効果】
本発明によれば、パック体をロックするためのロック手段を複数有し、かつ個々にロック解除が可能なであるため機器の小型化に有利であると共に、上記パック体を機器本体底面から着脱可能とした場合であっても、ロック解除によるパック体の落下を防止できるので、特に長尺のパック体を有する電子機器に採用して絶大なる効果が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to an electronic device in which a packed battery or the like can be attached and detached, and is particularly effective for an electronic device that requires a long pack body.
[0002]
[Prior art]
Currently, batteries, HDDs, and the like are packed and can be attached to and detached from an electronic device main body such as a personal computer to improve the performance of the electronic device (see, for example, Japanese Utility Model Publication No. 6-2431). ).
[0003]
Further, various configurations for attaching and detaching this kind of battery pack or the like (hereinafter referred to as a pack body) have been proposed in, for example, Japanese Patent Application Laid-Open Nos. 8-16278 and 9-6466.
[0004]
[Problems to be solved by the invention]
The size of the pack body targeted by the above-mentioned conventional proposal is about the size of a palm, and since the attachment / detachment operation was mainly intended to be performed with one hand, the attachment was released with one hand and the pack with the other hand. I was able to support my body. Therefore, the pack body can be easily attached and detached from the back side of the electronic device with the back side of the electronic device facing downward.
[0005]
However, when the size of the battery pack is increased in accordance with the demand for continuous use for a long time in a portable electronic device, a plurality of locking means are required to securely attach (lock) the pack body to the electronic device body. Become. If the plurality of locking means can be released with one hand, a mechanism for interlocking the locking means is required, which increases the size of the electronic device and impairs portability. On the other hand, for example, in a configuration in which the two locking means are operated with separate hands, there is no hand to support the pack body itself, so the pack body mounted on the back side of the device with the back surface of the electronic device facing downward It becomes difficult to attach and detach. In particular, this problem becomes conspicuous in a configuration in which the distance between the locking means is longer than the length of the pack body that is elongated and the palm is widened.
[0006]

Oppositely formed on the side wall 5. In the following, for convenience of explanation, the length of the first and second locking projections 6 and 8 (8 ′) in the front-rear direction of the main body 1 is simply referred to as length, and the length in the vertical direction is referred to as thickness. Further, the horizontal length of the first locking projection 6 (height from the side wall 4) is referred to as height.
[0012]
When the pack body 3 is stored in the storage portion 2, the side surfaces 9 and 10 that face the side walls 4 and 5 are engaged with the first and second locking projections 6 and 8 (8 '). A stop groove 11 (11 ′) is formed.
[0013]
The upper end of the locking groove 11 (11 ′) is opened, and the first and second locking protrusions 6 and 8 (8 ′) are arranged in a substantially straight line in the length direction as shown in FIG.

The surface of the indentation portion 15 (15 ′) gradually increases from the base groove 12 (12 ′) open end side toward the base groove 12 (12 ′) deepest portion with respect to the bottom surface of the groove 11 (11 ′). The cross section has a substantially arch shape that increases and then gradually decreases to a height equivalent to the bottom surface of the groove 11 (11 ′).
[0016]
Next, the attachment / detachment of the pack body 3 to / from the storage unit 2 will be described with reference to FIGS. 2 to 5 are cross-sectional views taken along the line AA ′ of FIG. 1, only the side wall 4 side of the storage unit 2 is shown, but as is clear from the above description, on the side wall 5 side, FIG. It goes without saying that the situation is similar. 2-5, the pack body 3 is transparently shown by a broken line.
[0017]
FIG. 2 shows a state in which the pack body 3 is attached to the storage portion 2. In this state, the first and second locking protrusions 6 and 8 are fitted in the first and second restricting grooves 13 and 14, respectively. ing. For this reason, the movement of the pack body 3 toward the back surface and bottom surface of the main body 1 is restricted.
[0018]
From the state shown in FIG. 2, when an operation button (to be described later) is pressed and the second locking projection 8 is slid to a position aligned substantially in line with the first locking projection 6 as shown in FIG. Since the engagement of the locking protrusion 8 with the second restricting groove 14 is released, the pack body 3 can be slid in the back direction of the main body 1.
[0019]
Therefore, as shown in FIG. 4, the pack body 3 is slid in the rear direction of the main body 1 and moved until the first and second locking projections 13 and 14 are located immediately below the open upper end of the base groove 12. As a result, the fitting of the first locking projection 6 into the first restricting groove 13 is released, so that the pack body 3 can be slid toward the bottom surface of the main body 1, and the pack body 3 can be moved as shown in FIG. It can be completely removed from the storage part 2. At this time, the second locking projection 14 returns to the position shown in FIG. 2 due to the pressing portion 15 acting when the pack body 3 slides. This operation will be described in detail in the description of the urging mechanism described later.
[0020]
On the other hand, the procedure for attaching the pack body 3 to the storage portion 2 is the reverse of the above-described removal procedure, and first the first and second locking projections 6 and 8 are fitted to the base groove 12 of the pack body 3. The pack body 3 is inserted from the bottom surface side of the storage portion 2 by aligning the open end of the base groove 12 with the first and second locking projections 6 and 8. At this time, the lower end of the second locking projection 8 comes into contact with the lower end of the base groove 12 and thereafter slides upward against the biasing force of the biasing mechanism by the insertion force of the pack body 3. As shown in FIG. 4, the first locking projection 6 is lifted to the horizontal level position. Therefore, from this state, by sliding the pack body 3 toward the front surface of the main body 1, as shown in FIG. 3, the first locking projections 6 are fitted in the first restricting grooves 13 and the second locking projections 8 are It will be located directly above the second restriction groove 14. Thereafter, fitting is completed by fitting the second locking protrusion 8 into the second restricting groove 14.
[0021]
6 to 8 are for explaining the urging mechanisms 20 and 20 'of the second locking projections 8 and 8' described above. The urging mechanisms 20 and 20 'have openings 7 and 7', respectively. Is disposed in the main body 1 communicating with the storage portion 2.
[0022]
The urging mechanisms 20 and 20 ′ are respectively operated by operating buttons 21 and 21 ′ mounted on the bottom surface side of the main body 1 so as to be slidable upward from the bottom surface side of the main body 1 and slightly slidable in the horizontal direction in the figure. The first to third suspended portions 22, 22 ′, 23, 23 ′, which are planted in order from the storage portion 2 side on the upper surface (the lower surface is the operation surface) of the operation buttons 21, 21 ′, respectively. 24, 24 ', and coil springs wound around the first hanging portions 22, 22' and having one end fixed to the main body 1 and the other end fixed to the second hanging portions 23, 23 '. Force means 25, 25 '.
[0023]
Since both ends of the urging means 25 and 25 ′ are fixed as described above, the operation buttons 21 and 21 ′ are always urged toward the bottom surface of the main body 1 and toward the storage portion 2. Further, the second locking projections 8 and 8 ′ are integrally attached to the tips of the second hanging portions 23 and 23 ′. Further, the tips of the third hanging portions 24 and 24 'are bent in the direction of the storage portion 2 to form a locking end portion, and integrally with the inner wall of the main body 1 near the openings 7 and 7', as shown in FIG. When the second locking projections 8 and 8 'are positioned at the upper ends of the openings 7 and 7' (this position is substantially horizontal with the first locking projection 6 as shown in FIG. 3), L-shaped locking portions 26 and 26 ′ for locking the locking end portions of the third hanging portions 24 and 24 ′ to the top are formed. Further, the vicinity of the top portion of the locking portions 26, 26 'facing the third hanging portions 24, 24' is slightly raised, and the lower end of the raised portion is tapered.
[0024]
Next, the operation of the urging mechanisms 20 and 20 ′ will be described.
[0025]
FIG. 8 shows a state in which the second locking projections 8 and 8 ′ are fitted in the second restriction grooves 14 and 14 ′, respectively, when the pack body 3 is completely attached to the storage portion 2 as shown in FIG. Is the same state. At this time, due to the urging force of the urging means 25, 25 ′, the locking end portion bent in the direction of the storage portion 2 at the tip of the third hanging portion 24, 24 ′ becomes the locking portion 26, 26 ′. The operation buttons 21 and 21 'are urged toward the bottom surface of the main body 1 while positioned so as to contact the third hanging portions 24 and 24' below the raised portion.
[0026]
In this state, when the operation buttons 21 and 21 ′ are pressed toward the upper surface of the main body 1 against the urging force of the urging means 25 and 25 ′, as shown in FIG. 6, the third hanging portions 24 and 24 ′ The locking end portion is pushed upward along the taper of the locking portions 26 and 26 ′ and can be pushed up to the upper side of the locking portions 26 and 26 ′. In this pushed-up state, the abutment of the locking end portions of the third hanging portions 24, 24 ′ to the locking portions 26, 26 ′ is released, and the biasing means 25, 25 ′ is in the direction of the storage portion 2 Due to the urging force, the locking end portions of the third hanging portions 24, 24 'are locked to the top portions of the locking portions 26, 26' as shown in FIG. In this locked state, as shown in FIGS. 3 and 4, the second locking protrusions 8 and 8 ′ are aligned with the first locking protrusion 6 in a straight line.
[0027]
The locking between the locking end portions of the third hanging portions 24 and 24 ′ and the top portions of the locking portions 26 and 26 ′ is released by attaching and detaching the pack body 3 to and from the storage portion 2.
[0028]
Specifically, for example, when the pack body 3 is slid from the state shown in FIG. 4 to the state shown in FIG. 5 in order to remove the pack body 3, the sliding pressing portions 15, 15 ′ become the second locking protrusions 8, It acts on 8 ', and pushes 2nd latching protrusion 8 and 8' inward of the main body 1 against the biasing force of biasing means 25 and 25 '. In this pushed-in state, the locking end portions of the third hanging portions 24, 24 ′ are separated from the tops of the locking portions 26, 26 ′, and are locked with the locking end portions of the third hanging portions 24, 24 ′. As shown in FIG. 7, the locking end portions of the third hanging portions 24 and 24 ′ are released by the urging force of the urging means 25 and 25 ′. When the pack body 3 is finally removed from the storage portion 2 as shown in FIG. 5 when it is biased below the raised portion of the locking portions 26 and 26 ′, the state shown in FIG. Return to.
[0029]
When the pack body 3 is attached to the storage portion 2 when the biasing mechanisms 20 and 20 ′ are in the state shown in FIG. 8, the biasing means 25 and 25 ′ are applied by the insertion force of the pack body 3 as described above. The second locking projections 8 and 8 'are lifted to the horizontal level position of the first locking projections 6 and 6' against the urging force of the third hanging projection 24 as shown in FIG. , 24 ′ and the tops of the locking portions 26, 26 ′ are designed so that they cannot be locked, and when the pack body 3 is inserted into the storage portion 2, As shown in FIG. 6, the locking end portions of the third hanging portions 24, 24 ′ and the top portions of the locking portions 26, 26 ′ are not locked.
[0030]
Further, in this embodiment, when the pack body 3 is attached to the storage portion 2, the urging mechanisms 20, 20 'are engaged with the locking end portions of the third hanging portions 24, 24' as shown in FIG. Even if the top portions of the stopper portions 26 and 26 'are locked, the pack body 3 can be mounted without any problem.
[0031]
That is, when the pack body 3 is inserted into the storage portion 2 when the urging mechanisms 20 and 20 ′ are in the state shown in FIG. 6, the push-in portions 15 and 15 ′ are the second in the same manner as the removal of the pack body 3 described above. Acting on the locking projections 8 and 8 ′, the second locking projections 8 and 8 ′ are pushed inward of the main body 1 against the biasing force of the biasing means 25 and 25 ′, and the third hanging portions 24 and 24 are pushed. The 'locking end portion of' is separated from the top of the locking portions 26, 26 '. As a result, the second locking projections 8 and 8 ′ are urged toward the bottom surface of the main body 1 by the urging force of the urging means 25 and 25 ′. Accordingly, the state is similar to the state of FIG. 8 described above, and can be mounted in the same manner.
[0032]
In the above description, it is described that the operation buttons 21 and 21 'are operated at the same time when the pack body 3 is removed. However, it is needless to say that it is not necessary to operate the operation buttons simultaneously because of the configuration. While supporting the pack body 3 with one hand, the operation buttons 21, 21 'can be operated in order with the other hand.
[0033]
In addition, although the present Example demonstrated the case where the accommodating part 2 was provided in the main body 1 back bottom side, this invention is not limited to this, A accommodating part is formed in any surface of the main body 1. There is no need to explain that.
[0034]
【The invention's effect】
According to the present invention, since there are a plurality of locking means for locking the pack body and each lock can be unlocked, it is advantageous for downsizing of the device, and the pack body is attached to and detached from the bottom surface of the device body. Even if it is possible, it is possible to prevent the pack body from dropping due to unlocking, so that it is particularly effective when employed in an electronic device having a long pack body.
