Title:
MULTIPLE OPTICAL AXIS PHOTOELECTRIC SENSOR
Document Type and Number:
Japanese Patent JP2019158369
Kind Code:
A
Abstract:
To maintain sealing of a housing over a long period of time.SOLUTION: For a multiple optical axis photoelectric sensor (100), the outer shapes of a light projector (110) and a light receiver (120) are respectively formed by a housing member (1). The housing member includes an outer shell case (10) having a body case (11) and a first cap member (12), an optical transparent plate (15), a first pressing member (20A), a second pressing member (20B), a first adhesive tape (17A), and a second adhesive tape (17B). A support portion (12a) is formed on an inner surface of the first cap member (12). An elastic member (18) is disposed between the second pressing member (20B) and a region supported by the support portion (12a) in the optical transparent plate (15). The optical transparent plate (15) is pressed against the first cap member (12) via the elastic member (18).SELECTED DRAWING: Figure 1
