一方、操作部側筐体2における第1の位置S11には、第1発光部51が存在しないため、表示部側筐体3における第1の位置S21に位置する第1受光部61aは、第1発光部51に対向しない。

第1受光部61は、表示部側筐体3において、回転軸41を中心とするとともに第1の円周C1に対向する第2の円周C2上に配置されている。
第2発光部52は、表示部側筐体3において、回転軸41と重なる位置に且つ第2受光部62に対向して配置されている。
第3受光部63は、操作部側筐体2において、回転軸41を中心とするとともに第3の円周C3に対向する第4の円周C4上に配置されている。
回転位置検出部71’を含む処理部70’は、第1実施形態における処理部70と同様の構成を有し、同様の動作を行う。
第3発光部53は、第3の円周C3上における設定角度φの倍数となる複数の位置のうちの一部または全部に配置される。第3の円周C3は、第3発光部53が位置する仮想的な円周である。第3の円周C3においては、回転軸41から表示部側筐体3の上端部側(図11における上側)の位置を「第2の位置S32」という。回転軸41から表示部側筐体3の下端部側(図11における下側)の位置を「第4の位置S34」という。また、第2の位置S32から時計回りに90度ずれた位置を「第1の位置S31」という。第2の位置S32から反時計回りに90度ずれた位置を「第3の位置S33」という。
一方、第1の位置S31及び第4の位置S34には、第3発光部53は配置されていない。なお、図11においては、第1の位置S31及び第4の位置S34を2点鎖線で示す。
一方、第4の位置S44には、第3受光部63は配置されていない。なお、図11においては、第4の位置S44を2点鎖線で示す。
また、第2発光部52から発光された光Rを第2受光部62で受光することにより、信号は、表示部側筐体3から操作部側筐体2へ伝達される。
例えば、第1実施形態においては、操作部側筐体2が第1筐体で(つまり、操作部側筐体2に第1発光部51が設けられ)、表示部側筐体3が第2筐体である(つまり、表示部側筐体3に第1受光部61が設けられている)が、これに制限されない。反対に、操作部側筐体2が第2筐体で(つまり、操作部側筐体2に第1受光部61が設けられ)、表示部側筐体3が第1筐体であっても(つまり、表示部側筐体3に第1発光部51が設けられていても)よい。
以下に、設定角度φが180度、120度、72度及び60度である場合における、前記式1及び式2の関係を満たす整数N、第1の個数L及び第2の個数Rの組み合わせの具体例について示す。
(N、L、R)=
(2,1,1)、(2,1,2)
(N、L、R)=
(3,1,2)、(3,1,3)、(3,2,2)、(3,2,3)
(N、L、R)=
(4,1,3)、(4,1,4)、
(4,2,2)、(4,2,3)、(4,2,4)、
(4,3,3)、(4,3,4)
(N、L、R)=
(5,1,4)、(5,1,5)、
(5,2,3)、(5,2,4)、(5,2,5)、
(5,3,3)、(5,3,4)、(5,3,5)、
(5,4,4)、(5,4,5)
(N、L、R)=
(6,1,5)、(6,1,6)、
(6,2,4)、(6,2,5)、(6,2,6)、
(6,3,3)、(6,3,4)、(6,3,5)、(6,3,6)、
(6,4,4)、(6,4,5)、(6,4,6)、
(6,5,5)、(6,5,6)
例えば、例1は、第1発光部51が位置S12のみに配置され、第1発光部51が位置S11,S13,S14には配置されておらず、また、第1受光部61が位置S21,S22,S23に配置され、第1受光部61が位置S24には配置されていない例(なお、第3発光部53及び第3受光部63は設けられていない)を示す。
