Through the internal combiner (C), the surrounding scene portion can be visually recognized within a predetermined field of view. Since the cylindrical member (E) is supported so as to be rotatable around a vertical axis and a horizontal axis, it can be directed to any position in the horizontal direction and the vertical direction. Therefore, when the inside of the cylindrical member (E) is viewed from the eyepiece (E1) of the cylindrical member (E), the surrounding scene portion which can be visually recognized at a time is limited, but the direction of the cylindrical member (E) is changed. By changing, all surrounding scenes can be visually recognized. The cylindrical member (E) has information display light (L) emitted from the optical information display means (D).

At this time, the display circuit (P) performs a display on the optical information display means (D) according to the target display signal (M1s) and the score integration signal (M4s). For example, when the scene portion visually recognized by the user of the viewing display device (U) is Mt. Fuji, the display target formed from three shining points arranged at the vertices of an equilateral triangle is Mt. Is displayed. When the scene portion visually recognized by the user is Lake Ashi, a display target formed by two shining points separated by a predetermined distance in the horizontal direction is displayed with Lake Ashi as a background. Such a display target can be a fixed display or a mobile display. For example, the display target displayed with Mt. Fuji as a background can be fixedly displayed at the top of Mt. Fuji, or can be displayed while moving around in a range overlapping Mt. Fuji.
