光学式传感器
摘要：
一种光学式传感器(10)，具备光源(20)、对从光源(20)出射的光进行导光的特性用导光部件(40)、配设于特性用导光部件(40)并根据特性用导光部件(40)的弯曲量来使光的光学特性变化的特性变化部(50)、对光学特性通过特性变化部(50)而变化且被特性用导光部件(40)导光后的光进行检测的检测部(60)。光学式传感器(10)还具有限制部件(80)和定位机构(90)，限制部件(80)沿着特性用导光部件(40)配设，至少抑制特性用导光部件(40)的扭转，限制特性用导光部件(40)的弯曲状态，定位机构(90)对特性用导光部件(40)和限制部件(80)进行保持，伴随着保持，至少在特性用导光部件(40)的周向上将特性变化部(50)定位。
摘要（英）：

An optical sensor (10) comprises: a light source (20); a characteristic light guide member (40) which guides light which is emitted from the light source (20); a characteristic change unit (50) which is positioned in the characteristic light guide member (40) and which changes an optical characteristic of the light according to a degree of curvature of the characteristic light guide member (40); and a detector unit (60) which detects light, the optical characteristic whereof is changed by the characteristic change unit (50) and which is guided by the characteristic light guide member (40). The optical sensor (10) further comprises: a restriction member (80) which is positioned along the characteristic light guide member (40), alleviates at least a twist of the characteristic light guide member (40), and restricts a curve state of the characteristic light guide member (40); and positioning mechanisms (90) which retain the characteristic light guide member (40) and the restriction member (80), and position the characteristic change unit (50) along with the retention at least in the circumference direction of the characteristic light guide member (40).
