Abstract

Disclosed is an information display device including: a projection portion that projects a projection image; and a cover portion that is driven to be changed between multiple states including a first state where the cover portion blocks at least part of an opening portion provided above a space that accommodates the projection portion and a second state where the cover portion is raised from the first state, in which when the projection portion performs projection in a state where the cover portion is controlled to be in the second state, a first image is projected onto a front window shield and a second image is projected onto the cover portion.

Claims

1. An information display device comprising:

a projection portion that projects a projection image; and

a cover portion that is driven to be changed between multiple states including a first state where the cover portion blocks at least part of an opening portion provided above a space that accommodates the projection portion and a second state where the cover portion is raised from the first state,

wherein when the projection portion performs projection in a state where the cover portion is controlled to be in the second state, a first image is projected onto a front window shield and a second image is projected onto the cover portion.

2. The information display device according to claim 1,

wherein the projection portion projects an image including the first image and the second image as one image, part of the one image projected onto the cover portion forms the second image, and part of the one image projected onto the front window shield without being interrupted by the cover portion forms the first image.

3. The information display device according to claim 1,

wherein a position where the first image is projected by the projection portion is vertically above a position where the second image is projected by the projection portion,

information relating to a traveling destination of a host vehicle is displayed in the first image, and

vehicle information indicating a state of the host vehicle is displayed in the second image.

4. The information display device according to claim 1,

wherein the projection portion includes:

a concave mirror that is disposed on an optical path of projection light of the first image and reflects the projection light of the first image toward the opening portion, and

a plane mirror that is disposed on an optical path of projection light of the second image and reflects the projection light of the second image toward the opening portion.

5. The information display device according to claim 1,

wherein a surface of the cover portion onto which the second image is projected is subjected to concave mirror treatment.

6. The information display device according to claim 1, further comprising:

a control unit that controls the cover portion so that the cover portion is changed from the first state to the second state based on an operating state of the host vehicle.

7. The information display device according to claim 1,

wherein a surface of the cover portion on a side where the second image is not projected is formed and attached to be approximately continuous to a curved surface or a planar surface formed by a peripheral member of the opening portion when the cover portion is in the first state.
