Abstract: An image reading device includes a plurality of light receiving parts arrayed regularly, a first light blocking member including a plurality of first openings arrayed corresponding respectively to the plurality of light receiving parts, and a plurality of microlenses arrayed corresponding respectively to the plurality of first openings. Each light receiving part included in the plurality of light receiving parts includes a plurality of light receiving pixels arrayed in a first direction as a main scanning direction. Each microlens included in the plurality of microlenses is object side telecentric. The plurality of microlenses, the first light blocking member and the plurality of light receiving parts are arranged so that light reflected by an object and passing through the microlens and the first opening corresponding to the microlens enters the plurality of light receiving pixels included in the light receiving part corresponding to the first opening.

Abstract: An image reading device includes a plurality of light-receiving pixels configured to receive reflected light; a first light-shielding member including a plurality of first openings and disposed between the plurality of light-receiving pixels and a reference surface; a second light-shielding member including a plurality of second openings and disposed between the plurality of first openings and the reference surface; and a plurality of condenser lenses disposed at a distance from the plurality of second openings. The plurality of condenser lenses, the second light-shielding member, the first light-shielding member, and the plurality of light-receiving pixels are disposed at positions at which reflected light sequentially passes through one of the condenser lenses corresponding to each light-receiving pixel, one of the second openings corresponding to the each light-receiving pixel, and one of the first openings corresponding to the each light-receiving pixel and enters the each light-receiving pixel.

Abstract: A lithium-manganese composite oxide represented by formula (1): Li1+x[(FeyNi1?y)zMn1?z]1?xO2 (1) wherein x, y, and z satisfy the following: 0<x??, 0?y<1.0, and 0<z?0.6, and wherein the content ratio of Li to the total content of Fe, Ni, and Mn (Li/(Fe+Ni+Mn)) is 1.55 or less on a molar ratio basis, the lithium-manganese composite oxide containing a crystalline phase having a layered rock-salt structure. This composite oxide is a novel material made from less resource-constrained and cheaper elements, and exhibits a high specific capacity, excellent charge-and-discharge cycle characteristics, and a high discharge capacity at a high current density (excellent rate characteristics), when used in the positive electrode material for lithium-ion secondary batteries.
