と、該位置情報に対向して配置されたセンサと、
前記記録媒体の中心位置に連結された駆動軸とを
備え、該駆動軸を介して回転する前記記録媒体の
位置情報を、前記センサからの出力変化に基づい
て検出するロータリエンコーダにおいて、弾性板
にその折曲線が方形となるように折曲加工を施し
て対向する折曲脚片を２組有する連結体を形成し
、これら折曲脚片のうちの一方の組を軸挿入孔を
有する結合体に固着すると共に、他方の組を前記
駆動軸より幾分大径の孔を有する規制板を介して
前記記録媒体に固着し、前記駆動軸を該規制板の
孔を挿通して前記結合体の軸挿入孔に挿入・固着
したことを特徴とするロータリエンコーダ。 a recording medium having positional information arranged in a circumferential direction; a sensor disposed opposite to the positional information;
A rotary encoder includes a drive shaft connected to a center position of the recording medium, and detects position information of the recording medium rotating via the drive shaft based on a change in output from the sensor. The bending process is performed so that the folding lines become rectangular to form a connected body having two pairs of opposing bent leg pieces, and one set of these bent leg pieces is formed into a combined body having a shaft insertion hole. At the same time, the other set is fixed to the recording medium through a regulating plate having a hole somewhat larger in diameter than the drive shaft, and the drive shaft is inserted through the hole in the regulating plate to form the combined body. A rotary encoder characterized by being inserted and fixed into a shaft insertion hole.
