MIRROR STRUCTURE AND HEAD-UP DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2017227682
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a mirror structure that allows a projection direction of an image to be changed to not only a vertical direction but also a lateral direction, and moreover, to an arbitrary direction, and to provide a head-up display device that is equipped with the mirror-structure.SOLUTION: A mirror structure comprises: a base member that is fixed at a prescribed position; a projection mirror that is arranged forward the base member, and makes image light reflect upon a reflection surface serving as a front face to project the image light onto a body to be projected; and three or more supporting members that are fixed to the base member, and support a rear face of the projection mirror. These three or more supporting members are arranged so that a supporting position in the rear face of the projection mirror by respective supporting members does not become one linear line. Each of at least two supporting members of the three or more supporting members is capable of changing pressing force with respect to the rear face of the projection mirror, and the change in the pressing force allows an interval between the projection mirror and the base member to be changed, respectively.SELECTED DRAWING: Figure 2
