Document Type and Number:

WIPO Patent Application WO/2016/151879

Kind Code:

A1

Abstract:

This laser distance measuring apparatus using a reflective member on the surface of which a transparent layer is formed, reduces the generation of stray light. The distance measuring apparatus (1) is provided with a light blocking part (17) on the surface of a deflecting member. The light blocking part (17) is provided on a border part between an incident light reflecting part which reflects, toward the outside, laser light (LL) emitted from a light emitting element (2), and a measuring light reflecting part which reflects, toward a light receiving element (8), measuring light (RL) reflected by an external object.
