Abstract:
A virtual image display device includes: a projection unit that projects an image display light; a concave mirror that reflects the image display light toward a virtual image presentation plane; and a driving mechanism that changes an orientation and position of the concave mirror. The driving mechanism rotates the concave mirror around a rotation axis perpendicular to both an incidence direction and an outgoing direction of a principal ray of the image display light on the concave mirror, and moves the concave mirror in a direction along the incidence direction of the principal ray of the image display light on the concave mirror in accordance with a change in an angle of the concave mirror around the rotation axis.

Claim (Index 7):
The virtual image display device according to  claim 1 , wherein\n defining a direction of the rotational axis of the concave mirror as x direction, defining the incidence direction of the image display light on the concave mirror as z direction, and defining a direction perpendicular to both the x direction and the z direction as y direction, the driving mechanism includes a first guide rail and a second guide rail configured to support the concave mirror and to enable the concave mirror to move in the z direction, the first guide rail is configured to extend linearly or in an arc, and the second guide rail is provided at a distance from the first guide rail in the y direction and is configured to extend linearly or in an arc such that at least one of the shape and orientation of the second guide rail is different from that of the first guide rail.
