It is determined by Lg1 (see FIG. 9A) and direction. FIG. 9 is a conceptual diagram for explaining the optical path lengths Lg1 to Lg3 of the first to third display lights L1 to L3.

  The virtual image V2 of the second display image located on the left side when viewed from the driver among the virtual images V1 to V3 is ahead (distant) from the imaging position of the virtual image V1 of the first display image. The image is formed so as to be located behind (front) from the front end of 1. The imaging position of the virtual image V2 is the length of the optical path of the second display light L2 from the second projector 521 to the driver's eye box EB via the second screen 522 and the second reflecting member 523. It is determined by Lg2 (see FIG. 9B) and the direction. In this embodiment, the second projector 521 is disposed behind (in front of) the first projector 511 so that the imaging position of the virtual image V2 is farther than the imaging position of the virtual image V1. The second reflecting member 523 is disposed in front (distant) from the first reflecting member 513, and the optical path length Lg2 of the second display light L2 is longer than the optical path length Lg1 of the first display light L1. (Lg2> Lg1). Further, the second reflecting member 522 is driven with respect to the line of sight E11 when the driver looks at the front so that the imaging position of the virtual image V2 is the left side when viewed from the driver with respect to the imaging position of the virtual image V1. It is arranged to be inclined at a predetermined angle (15 ° in the present embodiment) on the left side as viewed from the person.

  The virtual image V3 of the third display image located on the right side when viewed from the driver among the virtual images V1 to V3 is ahead (distant) from the imaging position of the virtual image V1 of the first display image. 1 is imaged so as to be located on the extension line S1 from the right end surface of 1 and to be located rearward (front) from the front end of the vehicle 1. The imaging position of the virtual image V3 is the length of the optical path of the third display light L3 from the third projector 531 to the driver's eye box EB via the third screen 532 and the third reflecting member 533. It is determined by Lg3 (see FIG. 9C) and the direction. In this embodiment, the third projector 532 is disposed behind (in front of) the first projector 511 so that the image formation position of the virtual image V3 is farther than the image formation position of the virtual image V1. The reflecting member 533 is arranged in front (distant) from the first reflecting member 513, and the optical path length Lg3 of the third display light L3 is longer than the optical path length Lg1 of the first display light L1. (Lg3> Lg1). Further, in order to set the imaging position of the virtual image V3 to the right side when viewed from the driver with respect to the imaging position of the virtual image V1, the third reflecting member 532 is set to the right side when viewed from the driver with respect to the driver's line of sight E11. They are arranged at a predetermined angle (15 ° in this embodiment).

The vehicle display apparatus 1000 according to the present embodiment includes indicators (first and second projectors 511 and 521 and first and second screens) that emit display lights L1 and L2 indicating first and second display images. 512, 522) and first and second reflecting members 513, 523 that reflect the display lights L1, L2 toward the driver to visually recognize the virtual images V1, V2 of the first and second display images. A vehicle display device in which the first and second reflecting members 513 and 523 are disposed in the instrument panel 13 of the vehicle 1,
The first partition member (the left wall portion 514a of the first middle case 514 and the right wall of the second middle case 524) disposed between the first and second reflecting members 513 and 523 and partitioning between the two. 524b), and the first partition member is formed such that the width on the driver side gradually narrows from the depth side toward the driver side.

  According to this, the driver side tip of the first partition member visually recognized by the driver becomes inconspicuous, and the driver's focus is increased when the line of sight is moved between the first and second reflecting members 513 and 523. Matching with the first partition member can be suppressed, unnecessary focal movement can be reduced, and instantaneous readability can be improved.

  Further, in the vehicle display device 1000 according to the present embodiment, the first partition member includes the end of the driver's eye box EB on the second reflecting member 523 side and the second reflecting member 513. The straight line S1 connecting the end of the reflecting member 523 side, the end of the driver's eyebox EB facing the second reflecting member 523 side, and the first reflecting member 513 of the second reflecting member 523. It is located between the straight line S2 which connected the edge part of the side.

  According to this, the driver visually recognizes the first and second reflecting members 513 and 523 from the end of the eye box EB, that is, visually recognizes the virtual image V1 of the first display image or the virtual image V2 of the second display image. In this case, the first partition member does not hinder the line of sight, and the visibility can be improved.

  In addition, the vehicular display device 1000 according to the present embodiment includes a visor 600 having a collar 610 extending from the upper side of the first and second reflecting members 513 and 523 toward the driver side. 610 is characterized in that at least the driver-side end 611 is formed so that the thickness gradually decreases from the depth side toward the driver side.

  According to this, the tip of the driver-side end 611 of the collar 610 visually recognized by the driver becomes inconspicuous, and the line of sight is moved between the windshield 14 and the first and second reflecting members 513 and 523. In this case, it is possible to suppress the driver from focusing on the heel part 610, and to reduce unnecessary focus movement.

  In the vehicular display device 1000 according to the present embodiment, the eaves portion 610 includes a straight line S5 connecting the lower end portion of the driver's eye box EB and the lower end portion of the transparent area of the windshield 14 of the vehicle 1, and driving. The straight line S6 connecting the upper end portion of the driver's eye box EB and the upper end portion of the first reflecting member 513 and the straight line S6 connecting the upper end portion of the driver's eye box EB and the upper end portion of the second reflecting member 523. It is located between and.

  According to this, the driver visually recognizes the scenery or the first and second reflecting members 513 and 523 from the end of the eye box EB, that is, visually recognizes the virtual images V1 and V2 of the scenery or the first and second display images. In this case, the collar 610 does not hinder the line of sight, and the visibility can be improved.
