PROBLEM TO BE SOLVED: To simultaneously reflect two to four sides of a figure on the basis of respective virtual images or the like of a front view which is viewed from the front, a back view which is viewed from the back and a side view which is viewed from the side on a plane mirror put in front or a display connected to a camera. SOLUTION: A two-sided mirror for reflection 2 comprising both right and left reflection plane mirrors 2a and 2b having an opening angle of about 90°, and a plane mirror for direct view 1 to be put in front of the two-sided mirror for reflection 2 are arranged so as to be opposed to each other in erect posture respectively, and an object image M is positioned within a mirror surface nearer to a side of either right or left reflection plane mirror 2a (or 2b) of the two-sided mirror for reflection 2 than a center line CL of the two-sided mirror for reflection 2, then the virtual image m<SB>2</SB>of the back view of the object image M, the virtual images m<SB>3</SB>and m<SB>4</SB>of the side views of the object image M and the virtual image m<SB>1</SB>of the front view which is viewed from the front of the object image M are simultaneously reflected on the plane mirror for direct view 1 by reflecting light beams L<SB>1</SB>and L<SB>2</SB>from the back of the object image M twice, and reflecting light beams L<SB>3</SB>and L<SB>4</SB>and L<SB>5</SB>and L<SB>6</SB>from the sides once.
