摘要： An image reader feeds a document to read document information at a still position from below a glass platen. The image reader is configured to include a document feeder unit feeding a document in a predetermined direction, a glass platen provided below the document feeder unit, an illumination unit provided on or above the glass platen and including a surface light source which is long in a direction orthogonal to the predetermined direction and illuminates the document, and a document reader unit reading document information at a still position from below the glass platen. Such an image reader can illuminate documents efficiently with less electric power and achieve thinning of the illumination unit.

摘要： A virtual image display device includes: an image display element that displays an image to be displayed as a virtual image; a propagation optical system that propagates light from the image display element; and a light guide member that guides the light propagated by the propagation optical system. The light guide member includes: a light beam incident part that introduces light including image information from the propagation optical system into the light guide member; an image extractor that extracts the light including image information from an inside of the light guide member; and an image emitter that emits the light including image information to an outside of the light guide member. The propagation optical system includes one or more optical members each having a curved surface shape that is non-rotationally symmetric with respect to an optical axis.

摘要： A zoom lens system includes a first lens group having positive refractive power; a second lens group having negative refractive power; and a rear group, the first lens group, arranged in that order from an object side. The second lens group includes a second lens group-a having negative refractive power and a second lens group-b having negative refractive power arranged in that order from the object side. During a change in a focus from a short focal length end to a long focal length end to change a magnification power, a distance between the first lens group and the second lens group-a increases, a distance between the second lens group-a and the second lens group-b is changeable or stationary, and a distance between the second lens group-b and the rear lens group decreases.
