Title:
LIMITED-REFLECTION-TYPE SENSOR
Document Type and Number:
WIPO Patent Application WO/2019/176284
Kind Code:
A1
Abstract:
[Problem] To provide a limited-reflection-type sensor that makes simple, accurate positioning during lens attachment and dust resistance enhancement possible. [Solution] This limited-reflection-type sensor (100) irradiates light emitted from a light emission part (32) onto an object detection area via an emission light lens (22) and receives light reflected by an object in the object detection area with a light reception part (33) via a reflected light lens (23). The limited-reflection-type sensor (100) has a housing part (10) that comprises a locking part (13) formed on a side surface thereof and a first opening part (15) facing the object detection area and accommodates the light emission part (32) and light reception part (33), and a lens part (20) that comprises a light incidence and emission part (21) formed integrally with the emission light lens (22) and reflected light lens (23) and a side surface covering part (24) consisting of an end part of the incidence and emission part (21) extending along the side surface. The lens part (20) covers the first opening part (15) with the incidence and emission part (21) and the side surface covering part (24) is locked by the locking part (13).
