PURPOSE:To permit easy and sure obtaining of a focused photograph having good quality by providing an auxiliary mirror which can be fixed at a specified angle on one side of a half mirror and fixing a focal length in such a manner that a camera part focuses at the position where both the central optical axes of the half mirror and the auxiliary mirror intersect. CONSTITUTION:The half mirror is provided to the front face of a cabinet in which a dark room state is maintained. The camera part provided with a camera lens opposite to the rear face of the half mirror is housed in the cabinet. The auxiliary mirror which is positioned on at least one side of the half mirror and can be fixed at the specified angle is hinged to the cabinet. The focal length is so fixed that the camera part focuses at the position where both the central optical axes of the half mirror and the auxiliary mirror intersect. The focal length is so set that the camera part 8 focuses at the point where the central optical axes of the half mirror 4 and the auxiliary mirror 5 intersect when a subject person locates in a position where his figure is projected on both of the half mirror 4 and the auxiliary mirror 5 on the cabinet 1 side part at the time of photographing. The exactly focused photograph having good saturation is thereby obtd.
