  • Publication number: 20240128294
    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.

  • Patent number: 11924937
    Abstract: A light-emitting device includes an optical member including first and second light emitting elements, first and second light condenser portions, and a light guide portion. The first light condenser portion is disposed at a position corresponding to the first light-emitting element, and condenses a portion of light emitted from the first light-emitting element. The second light condenser portion surrounds the first light condenser portion, and condenses a portion of the light that is not incident to the first light condenser portion among the light emitted from the first light-emitting element. The light guide portion is disposed at a periphery of the second light condenser portion and at a position corresponding to the second light-emitting element, and guides light emitted from the second light-emitting element by causing total reflection in an interior of the light guide portion.

  • Publication number: 20200292870
    Abstract: A display device includes a display panel, a backlight unit, and a fixing member. The display panel includes a display area in which images are displayed and a non-display area disposed to surround the display area. The backlight unit is disposed opposite a back surface of the display panel. The fixing member is fixed between the display panel and the backlight unit to fix the display panel and the backlight together. The fixing member includes a light blocking portion having a light blocking property and a light passing portion having light transmissivity. The light blocking portion is disposed in an area overlapping the non-display area. The light passing portion is disposed inner than the light blocking portion.

  • Patent number: 10585227
    Abstract: A lighting device includes a light guide plate and a light source. The light guide plate includes a plate-like member. The light source is arranged so as to oppose an end surface of the light guide plate and emits light to the end surface. The light guide plate has a light incidence surface, an opposite surface of incidence, and a through-hole. In a straight traveling direction of light traveling straight inside the light guide plate from the light incidence surface to the opposite surface of incidence along an optical axis direction of the light, a region on the opposite surface of incidence side with respect to the through-hole is a shielded region where the light traveling straight along the optical axis direction is interrupted by the through-hole. Stepwise step parts that emit light from the light source to the shielded region side are provided adjacent to the shielded region.

  • Publication number: 20190227218
    Abstract: A lighting device includes a light source configured to emit light and a light guide plate of a plate shape having an edge surface that is opposite the light source and toward which light is emitted by the light source. The light guide plate includes a through-hole penetrating therethrough in a plate-thickness direction and a region around the through-hole, and the region includes a highly refractive region positioned at least on an opposite side from the light source and having a refractive index higher than a refractive index of another region.

  • Patent number: 6139948
    Abstract: A membrane formed by coating an aqueous coating liquid comprising an antistatic agent or anticlouding agent on one or both surfaces of an aliphatic polyester film comprising a specific amount of a lubricant or an antiblocking agent, can remarkably improve adhesion of the membrane (antistatic layer or anticlouding layer) to the aliphatic polyester film, and thus the effect of the membrane (antistatic effect or anticlouding effect) can be continuously exhibited for a long period.

  • Patent number: 4559545
    Abstract: A recording apparatus wherein a recording medium is fed through the gap between recording electrodes and a rear electrode which are arranged to face each other. A magnetic toner is supplied to the gap between the recording medium and the recording electrodes. While under the state where a magnetic field is formed around the recording electrodes to retain toner particles on the recording electrodes, voltage pulses are selectively applied between the recording electrodes and the rear electrode to thereby transfer the toner particles on the recording electrodes to thereby the recording medium by means of coulomb forces for effecting a recording. The recording electrodes are constituted by recording electrode patterns mounted on a rigid board of an insulating non-magnetic material attached to the periphery of a cylindrical hollow member which houses a rotatable magnet roll.
