ロック部材11がロック位置に位置するとき、操作部11aは、モジュール20の筐体から突出しない(図5(A)参照)。本実施形態では、ロック部材11がロック位置に位置するときには、操作部11aは、機器本体1の筐体に形成された切り欠き部3に収容されて、機器本体1の筐体からも突出しない。
ロック部材11がロック解除位置に位置するとき、操作部11aは、モジュール20の筐体から突出する(図5(B)参照)。本実施形態では、ロック部材11がロック解除位置に位置するときには、操作部11aは、機器本体1の筐体に形成された切り欠き部3に収容されることなく、機器本体1の筐体からも突出する。
固定マウント部12には、複数の貫通穴12aが隅部に形成されている。複数のビス19を、貫通穴12aに挿通し、モジュールカバー18に形成されたタップ穴に締結固定すると、モジュールの組み立てが完了する。
図7(A)は、本実施形態に係る機器本体からモジュールを取り外した状態を、背面側から見た場合の斜視図である。図7(B)は、その状態での分解斜視図である。以下では、実施形態1との相違点のみを説明し、実施形態1の場合と同様の構成要素については既に使用した符号を用いることで、それらの詳細な説明を省略する。このような説明の省略は、後述の実施形態でも同じである。
図8(A)に示すように、環状部42がロック位置に位置するとき、操作部41は、モジュール20の筐体からわずかに突出する。本実施形態では、環状部42がロック位置に位置するときには、操作部41は、機器本体1の筐体からもわずかに突出する。
図8(B)に示すように、環状部42がロック解除位置に位置するとき、操作部41はモジュール20の筐体からの突出量が増加する。本実施形態では、環状部42がロック解除位置に位置するときには、操作部41は、機器本体1の筐体からの突出量も増加する。
ここで、図11、12を参照して、放熱部材107、コネクタ部120、係合凹部123、ロック操作部141a、コネクタ部210、係合凸部230の位置関係について詳細を説明する。機器本体100の背面において、放熱部材107よりも下側にコネクタ部120が配されている。したがって、モジュール200の前面においてコネクタ部210は、機器本体100にモジュール200が装着された状態において凹部206よりも上側に配されている。この構成により、図10に示したような、最も使用頻度が高い、第1の面S1が重力方向とは反対側に面する機器本体100の正位置(第1の状態)において、放熱部材107から拡散された熱が、コネクタ側に伝わる度合を小さくすることが出来る。
また、機器本体100の背面において、係合凹部123は、コネクタ部120の近傍であって、コネクタ部120よりも外側(筐体130の外形に近い側)に設けられている。そして、係合凹部123は、コネクタ部120を挟んでロック操作部141aとは反対側であって、機器本体100の背面の4隅のうち、ロック操作部141aに近接する2つの隅とは異なる2つ隅の近傍に設けられている。したがって、モジュール200の前面において係合凸部230は、コネクタ部210の近傍であって、機器本体100がモジュール200に装着された状態でロック操作部141aと対向するモジュール200の領域とコネクタ部210を挟んで反対側に設けられる。なお、コネクタ部210の長手方向の辺に対して、2つの係合凸部230の接線が略平行な位置関係となる。以上説明した構成により、機器本体100およびモジュール200の外形寸法を極力小型化できる。また、例えば、コネクタ部210が外部に露出した状態において、コネクタ部210よりも先に係合凸部230が外部と接触する確率を高くすることができるため、より効果的にコネクタ部210を保護することが出来る。
機器本体100にて第1のマウント部M1の内側には凸部126が形成されている。凸部126は、第1のマウント基準面MS1よりも内側にあって当該第1のマウント基準面MS1よりも後方(モジュール200側)に突出している。凸部126は、コネクタ部120を囲むように周方向に形成されている。回動部材であるロック部材141に形成された爪部141cは、凸部126よりも外周側に位置し、第1のマウント基準面MS1よりも後方に突出した位置において内側に延出している。つまり爪部141cの一部は光軸方向から見た場合、光軸に直交する径方向において第1のマウント基準面MS1と同じ位置にある。爪部141cの一部は、光軸と平行な方向において第1のマウント基準面MS1と重畳した位置となる。このため、機器本体100とモジュール200とを締結する爪部間に水や異物が侵入することを防ぎ、爪部同士の係合関係が緩むことを抑制できる。

・USB(Universal Serial Bus)の通信用接続部100A2
・HDMI(登録商標)(High-Definition Multimedia Interface)の通信用接続部100A3。
なお、ここでは/M_CONNECT端子は機器本体100側に置いて接地されている構成で説明しているが、機器本体100がその端子の電圧レベルを制御する構成でも構わない。
なお、本発明の構成については、前記実施形態に例示したものに限定されず、材質、形状、寸法、形態、数、配置箇所等は、本発明の要旨を逸脱しない範囲において適宜変更可能である。
