Head-up display apparatus
First Claim
1. A head-up display apparatus comprising:
- an image output device configured to output an image; and
an optical system that projects the image outputted from the image output device to a windshield of a vehicle in order to display a virtual image within the vehicle, wherein;
the optical system includes;
a first optical member receiving the image outputted from the image output device and reflecting the received image, the first optical member having an optical path, along which the image reflected by the first optical member travels; and
a second optical member receiving the image reflected by the first optical member and projecting the received image to the windshield by reflecting the received image, the second optical member having an optical path, along which the image reflected by the second optical member travels;
the second optical member has a position changer that rotates the second optical member within a predetermined rotation angle in order to change the optical path of the second optical member relative to the windshield such that a projection position of the image reflected by the second optical member on the windshield is changed; and
the first optical member has an adjuster that changes a position of the first optical member in order to adjust the optical path of the first optical member relative to the second optical member such that the optical path of the second optical member relative to the windshield is adjusted.

Abstract
A head-up display apparatus includes an image output device and an optical system. The optical system includes a first and second optical members. The first optical member receives the image from the image output device. The second optical member receives the image from the first optical member and projects the image to a vehicle windshield. The second optical member has a position changer that rotates the second optical member to change an optical path thereof relative to the windshield to change a projection position of the image on the windshield. The first optical member has an adjuster that changes a position of the first optical member in order to adjust an optical path thereof relative to the second optical member to adjust the optical path of the second optical member.
