An evidence marker is formed by folding a paper board 1 of a sector shape composed of five consecutive and connected triangles (1A-1E, Fig 2) of which the first and fifth triangles overlap and are fixed to each other to form a square cone. An arrow indicator 2 is rotatably attached to one of the triangles by a positioning button B fitted into a positioning hole defined in the triangle. A bottom board is divided into two halves that are folded to overlap each other and is provided with scale-like indexing mark 13 to serve as a measuring means when the evidence marked by the marker is photographed, with the marker in shot. The bottom board may have apertures to allow a fixing bar to be used with the marker. |
