Abstract
Description
なお、携帯端末装置を含む電子機器の防水規格として、例えばJIS/IEC(国際電気標準会議)におけるIPX7という保護等級では、温度範囲15~35℃等で、装置最下端が水面から1mの潜水で、試験時間30分でも浸水しない程度の防水水準が設定されている。
本発明は、装置本体に設けられ電池を収容する電池室を塞ぐ電池カバーと、該電池カバーを前記装置本体にロックするロック機構とを有する携帯端末装置において、
前記ロック機構は、
前記電池カバーに移動可能に設けられたレバー部材と、前記レバー部材を操作する操作手段と、前記装置本体に設けられ前記操作手段の操作に伴い前記レバー部材が移動して該レバー部材の両端部が係合する係合部材とを有し、
前記電池カバーは、前記レバー部材が前記係合部材と係合することにより該係合部材からの反発力で前記装置本体側に押圧されることを特徴とする。
図1は、本発明の実施の形態の携帯端末装置を前面側から見た外観図であり、図2は、その背面側から見た外観図である。
図2において、携帯端末装置10の背面側には、電池20を収容する電池室26の開口部26a(図3参照)を塞ぐ電池カバー22を有している。
この携帯端末装置10には、物品(商品)に付されたコード情報を読み取る不図示のスキャナユニット(マーク読取ユニット)が搭載されている。
本実施の形態では、電池20は充電池であり、装置本体12の背面側に形成された電池室26に着脱可能に収容されている。この電池室26は、開口部26aを電池カバー22で覆うことによって防水性能が維持されるようになっている。
この電池カバー22は、外側カバー22Aと内側カバー22Bとを積層した一体構造を有している。
図5に示すように、外側カバー22Aは、合成樹脂等(例えばポリカーボネート)の弾性材料からなり、中央にカバー本体23を有している。この外側カバー22Aは、長手方向(図5のY方向)の上方側に形成されたアームガイド38とロック機構60とを有している。
本実施の形態では、内側カバー22Bは、外側カバー22Aとは異なる材料からなる補強部材としての補強プレート46と、該補強プレート46の外側カバー22A側面に設けられる接着材としての粘着テープ44と、補強プレート46の粘着テープ44側と反対側に設けられるシール部材としてのパッキン48とを有している。こうして、内側カバー22Bは、粘着テープ44により外側カバー22Aに貼り付けて積層される。
この補強プレート46は、中央に開口50aを有するプレート本体50と、このプレート本体50の長手方向(図6のY方向)の上方側に形成されたカバー部51と、長手方向の下方側に突出する左右一対の突起56,57と、プレート本体50の幅方向(図6のX方向)の左右端部に形成された左・右リブ部53、54と、を有している。
また、前述したように、電池カバー22には、外側カバー22Aの爪40、41よりも幅方向の内側に、内側カバー22Bの補強プレート46の突起56,57が突出されている。このため、この突起56,57が電池室26の開口部26aの下端側に掛止されて掛止部が補強されることになる。
ロック機構60は、電池カバー22で電池室26の開口部26aを覆うときに、該電池カバー22を装置本体12側に押し付けてロックする機構である。このロックにより、電池カバー22は装置本体12側に押し付けられて、電池室26の内部の防水性が維持される。
操作ツマミ62は、レバーアーム61の長手方向の中央に設けられている。そして、操作ツマミ62の操作に伴いレバーアーム61は長手方向に移動する。
図7及び図8において、レバーアーム61は、第1端部65aを有する矩形枠状の枠体部65と、この枠体部65に対し図7の下方(Z方向)に段部を有して水平に延在する平板部66と、この平板部66から図の上方(Z方向)にわずかな段部を有して水平に延在する第2端部67とを有している。
これにより、レバーアーム61の第1端部65a及び第2端部67に夫々外力が作用して、レバーアーム61の各端部が変形するのを防止することができる。
図9において、操作ツマミ62を矢印B方向に回動操作すると、レバーアーム61は矢印C方向に移動する。これにより、レバーアーム61の第1端部65a及び第2端部67が、係合ピン34,35(図3参照)に係合して電池カバー22がロックされる。
また、操作ツマミ62を反対方向に回動操作すると、レバーアーム61は矢印Cと反対方向に移動して、電池カバー22のロックが解除される。
図10Aは、係合ピン34,35(図3参照)に対するレバーアーム61のロック解除状態を示し、図10Bは、係合ピン34,35に対するレバーアーム61のロック状態を示す。
すなわち、この状態では、レバーアーム61の第1端部65a及び第2端部67は、係合ピン34,35に対し、長手方向(X方向)に離れたところに位置している。これは、電池カバー22が単に電池室26の開口部26aを覆っている状態であり、ロックはされていない。
なお、この操作ツマミ62の回動は、実際には、電池カバー22で電池室26の開口部26aを覆い、その状態で操作ツマミ62を回動させる。
本実施の形態によれば、ロック機構60は、レバーアーム61と、操作ツマミ62、及び装置本体12に設けられた係合ピン34,35を有し、レバーアーム61が係合ピン34,35に係合すると、電池カバー22は係合ピン34,35からの反発力で装置本体12側に押圧されるので、電池室26の防水性を確保することができる。
