Abstract: A light emitting device includes an excitation light source that emits excitation light, a wavelength conversion member, a light guide, and a light guide distal end member. The wavelength conversion member absorbs the excitation light emitted from the excitation light source, converts its wavelength, and releases light of a predetermined wavelength band. The light guide in which the center part (core) of its cross section has a refractive index that is higher than the refractive index of the peripheral portion (cladding) guides the excitation light emitted from the excitation light source to the wavelength conversion member. The light guide distal end member supports a distal end of the light guide on the wavelength conversion member side. The light guide distal end member is formed from a material that reflects the excitation light and/or the light that has undergone wavelength conversion.

Abstract: A method of rendering a page, which includes starting obtaining operation for obtaining a page made by a markup language, performing a text browsing mode operation on obtained part of data of the page in parallel with the obtaining operation of the page, judging whether or not acquisition of definition information which is information to be applied to the entire page so as to render the page as designated by a markup language document of the page is finished, and switching onscreen representation, depending on a result of the judging, from onscreen representation in a text browsing mode to onscreen representation in which the definition information is applied.
