摘要： A cabinet of a projection type display unit includes a base cabinet on which main component parts are mounted, and a top cover made from sheet metal which is mounted so as to cover the base cabinet, wherein a rear face portion of the top cover is formed in the shape of a curved surface being laid-down U-shaped in side view. The U-shaped curved surface is formed on an ergonomic basis, so that the rear face portion can be gripped securely even with one hand. On the back side of the top cover, bosses are integrally formed by use of a resin which is a different material from the sheet metal of the top cover, and the base cabinet and the top cover are fixed by fastening screws to the bosses from the base cabinet side.

摘要： As regards a surface light source device for use with back-light or the like of a transmissive display panel, the efficiency of the cooling structure for the device will be improved and dust and dirt will be prevented from adhering.The surface light source device has a housing, a diffuser panel, a reflective plate, lamps, and an electric circuit portion. The housing has a window portion located ahead, a base portion located behind and side portions forming a flat space by connecting the two. The diffuser panel is mounted to the window portion of the housing. The reflective plate is supported by the side portions and partitions the flat space into a closed space ahead and an open space behind to be interposed therebetween. The lamps are housed in the closed space, and are positioned right above the reflective plate and right under the diffuser panel to radiate light toward the diffuser panel. The electric circuit portion is housed in the open space, and is electrically connected to the lamps to light them up. On the side portions of the housing, there are formed openings, through which cooling air supplied from outside is introduced into the open space to diffuse heat accumulated within the housing.
摘要翻译：关于与透射型显示面板的背光等一起使用的面光源装置，能够提高装置的冷却结构的效率，防止灰尘和污物附着。表面光源装置具有壳体，扩散板，反射板，灯和电路部分。壳体具有位于前方的窗部，位于后方的基部和通过连接两者而形成平坦空间的侧部。扩散板安装到壳体的窗口部分。反射板由侧部支撑并将平坦空间分隔成前面的封闭空间和后面的敞开空间。灯被容纳在封闭的空间中，并且位于反射板的正上方并且位于扩散器面板的正下方，以朝向散射板辐射光。电路部分容纳在开放空间中，并且电连接到灯以使它们点亮。在壳体的侧部形成开口，通过该开口将从外部供应的冷却空气引入到开放空间中以扩散积聚在壳体内的热量。

摘要： A projector 10 projects an image onto a set of screens 14 for image formation. The set of screens 14 includes a first screen 50 and second screens 54 and 56. The projector includes a housing 20, a first screen fixture 74 and a second screen fixture 76. The housing 20 has an opening 30 for fitting the first screen 50 therein. The first screen fixture 74 positions the first screen 50 in the housing opening 30 and fixes an inner surface of the first screen 50 adhesively to the housing 20. The second screen fixture 76 is positioned between the first screen 50 and the first screen fixture 74, and fixes the second screens 54 and 56 between itself and the inside of the first screen 50.

摘要： Disclosed is a flat display allowed to facilitate a maintenance work for a back light unit contained in the flat display. The flat display includes a frame, display unit, back light unit, and chassis. The frame is positioned on the front side and has a window portion. The display unit, which is of a transmission type and is formed in a flat shape, is assembled from the rear side to the frame in such a manner as to be matched with the window portion to form an image screen. The chassis is positioned on the rear side and is engaged with the frame while putting the display unit therebetween to form a flat containing space on the back surface side of the display unit. The back light unit 3 is a surface light source which is pre-assembled using a flat case, and is removably insertable in the containing space. The back light unit functions to illuminate the transmission type display unit from the back surface side.
