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 2):
The virtual image display device according to  claim 1 , wherein\n the driving mechanism: a) moves the concave mirror in the incidence direction of the principal ray of the image display light on the concave mirror when the angle of the concave mirror is changed to reduce an incidence angle of the image display light on the concave mirror, and b) moves the concave mirror in a direction opposite to the incidence direction of the principal ray of the image display light on the concave mirror when the angle of the concave mirror is changed to enlarge an incidence angle of the image display light on the concave mirror.
