Abstract
A head-mount type display device has a first display unit for left eye, a second display unit for right eye, a guide that guides the first and second display units to slide them in a longitudinal way, and an adjustment mechanism that adjust a distance between the first and second display units. The adjustment mechanism includes a revolving member having a shaft, a left-side arm having a first end that rotatively connects the first display unit and a second end that rotatively connects the revolving member, and a right-side arm having a third end that rotatively connects the second display unit and a fourth end that rotatively connects the revolving member. When the revolving member revolves around the shaft, the first and second display units slide by a same distance from the shaft in the longitudinal way along the guide.
