An organic luminescence device capable of luminescence at a high efficiency, a high luminance and high durability is formed by a pair of electrodes comprising an anode and a cathode, and at least one organic layer disposed between the electrodes. The sheet conveying device includes a pair of drive pulleys, a pair of driven pulleys, a pair of chains each being passed over one drive pulley and one driven pulley, and a clamper affixed to the chains at opposite ends thereof. At least a region of the metal layer on the electrodes, wherein the metal layer is present in a discontinuous film form, is so changed by oxidization to a continuous film that more improved effect on prevention of corrosion is achievable. Based upon the desired route and the contextual information, a direction may be generated for presentation to one or more users, and the generated direction may be output for presentation. In the preferred embodiment, the compression material is ring-shaped and exhibits substantially the same thermal expansion coefficient as the window. The reflector according to the present disclosure includes a compact construction that allows for effective light reflection.
