度の回折角として反射するように記録する。That is, the hologram sheet attached to the hologram cover glass 11 can change the incident angle and the diffraction angle of the external light 4 during reproduction by changing the incident angles of the laser light from two directions during exposure. In the present invention, the light is reflected by the flat hologram cover glass 11 as a diffraction angle having the same angle as the reflection angle of the cylindrical cover glass 3 conventionally used with respect to the incident angle of the external light 4 incident on the corresponding position. To record.

形状のカバーガラスに入射した如く反射する。Further, as described above, the diffraction wavelengths recorded on the hologram cover glass 11 are triple-exposed using lasers of three wavelengths of RGB so that the same diffracted light corresponds to the incident light in the entire visible light range. . As a result, most of the reflected external light 4 consisting of white light is reflected as if it were incident on the cylindrical cover glass.

る。The hologram cover glass 11 has a planar shape unlike the conventional cylindrical cover glass 3, and therefore, the distance (A) from the lower edge of the conventional cylindrical cover glass 3 to the lower side of the scale plate 7 is: The hologram cover glass 11 of the present invention has a distance (A ′) from the scale plate 7 that is sufficiently short as A> A ′, and the reflection of the external light 4 having the same incident angle corresponds to the hologram cover glass 11 and the conventional cylindrical shape. Since the light is reflected in the same direction as that of the cover glass 3, the projecting length of the instrument hood 5 can be shortened. Therefore, the space in front of the driver's seat can be widened, and the instrument panel can be downsized.
