Claims

[Claims for Utility Model Registration] (1) Display light from a display unit disposed inside the jaw of a helmet is reflected by the shield of the helmet to form a virtual display image in front of the helmet; A display device in which a virtual image of a display image can be viewed from inside through a shield, the unit driving unit changing the direction of the display unit using a point within the optical axis of the display light or a point near the optical axis as a fulcrum. means, a reference light source that indicates the direction of the fulcrum when looking into the shield by reflecting radiation on the shield, angle detection means that detects the orientation of the display unit, and an outer surface of the shield. a transparent touch panel disposed on the touch panel, and a control means for identifying a pressed point on the touch panel, detecting the orientation of the display unit by the angle detection means, and controlling the orientation of the display unit by the unit driving means, A display device characterized in that the control means controls the position of the display unit so that the optical axis of the display light is directed in the direction of the pressing point identified by the control means. (2) The display device according to claim 1, wherein the display unit is supported by two orthogonal axes, and the intersection of the two axes is the fulcrum. (3) The display device according to claim 1, wherein the reference light source is a point light source movably arranged at the position of the fulcrum.
