Abstract
A marker apparatus including a retroreflector constituted by three reflective surfaces arranged on three surfaces of a trigonal pyramid and a light source disposed on an optical axis of the retroreflector. A lens is provided in front of the retroreflector and a condensing lens is formed on the lens for condensing light emitting from the light source. A plurality of retroreflectors are provided continuously on the same plane in such a manner that directions of the three reflective surfaces, which constitute each of the retroreflector, are different from one another, and a front view of the retroreflector is regular hexagonal. A wall surface is formed between the three reflective surfaces constituting each retroreflector so that the wall surface directed in parallel with an optical axis.
