  • Publication number: 20250044415
    Abstract: In order to make it possible for a sensing sensor to secure the appearance of the product while enabling detection of various masking materials, such as those with low reflectance or in sheet form, the sensing sensor comprises a sensor part that detects an object to be detected and a masking detection structure that detects a masking material that nullifies a detection function of the sensor part. The masking detection structure comprises a light source and a light receiver housed in a casing together with the sensor part, and a light transmission window that closes an opening formed in the casing. The light transmitting window has a concave portion recessed toward an inside of the casing, and light emitted from the light source is transmitted from the inside of the casing to the outside thereof through the concave portion.
