    • The light directed from a light source to a concave mirror and the light directed from a display device to an eyepiece optical system are intersected by each other in a layout. This allows the light source, the concave mirror, and the display device to be arranged in compactness adjacent to the eyepiece optical system without increasing the optical power of an illumination optical system. As the result, the apparatus can easily be minimized in the thickness or the overall size. A hologram optical element is provided where the relationship between the wavelength range Δλ1 at half of the diffraction efficiency of each of the three primary colors of the light in the hologram optical element and the wavelength range Δλ2 at half of the intensity of each of the three primary colors of the light emitted from the light source is defined by Δλ1
    • 从光源引导到凹面镜的光和从显示装置指向目镜光学系统的光在布局中彼此相交。 这允许光源,凹面镜和显示装置在与目镜光学系统相邻的紧凑状态下布置,而不增加照明光学系统的光功率。 结果,该装置可以容易地在厚度或整体尺寸上最小化。 提供了一种全息光学元件,其中全息光学元件中的光的三原色中的每一种的衍射效率的一半的波长范围&Dgr;λ1与波长范围&Dgr;λ2之间的关系为强度的一半 从光源发射的光的三原色中的每一个由&Dgr;λ1<&Dgr;λ2定义。 因此,从光源发射的光的R,G和B颜色中的每一个的期望波长的分量可以通过全息光学元件的作用被衍射,然后被引导到观察者的瞳孔。 这允许在颜色再现区域中增加图像并且提高质量,而与时分模式下的显示装置无关。

    • An image reading apparatus equipped with an image reading apparatus unit (B) provided a platen (33) and reading means (31) that reads an original, a document feeder (A) provided conveyance paths (P1), (P2), and (P3) leading from a sheet supply tray (1) to a discharge tray (34) via the platen (33) on a top surface of the image reading apparatus unit (B), a hinge device (12) that openably connects the document feeder (A) to a top surface of the image reading apparatus unit (B), wherein an image reading unit (50) is equipped in the document feeder (A), and the image reading unit (50) is integrally connected to a support member fastened to the hinge device (12). This configuration prevents mispositioning or misalignment of a reading line of the image reading unit (50) caused by repeated opening and closing of the document feeder (A).
