20090116080 | IMAGE READING APPARATUS - An image reading apparatus includes a plurality of LEDs, a light guide member that linearly illuminates, an LED control circuit that controls amounts of light of each LED based on reference light quantities and corrects the reference light quantities, an image sensor such as a CCD that scans an original when each of the LEDs are put on simultaneously, an analog front end (AFE) that generates read image data corresponding to the original, and a light modulation reference member disposed at a position where imaging by the CCD is possible. During correction of each of the reference light quantities, the LED control circuit puts each LED on individually. Each LED is then modulated by correcting the present outputs based on the modulated light image data generated by sensing the light modulation reference member when each of the LEDs is on and the reference light quantities based on target outputs corresponding to each of the LEDs. | 05-07-2009 |
20090212483 | SHEET FEEDING DEVICE - Imaging target media stacked in a tray are bent in a width direction orthogonal to a transmission direction so that rigidity of the imaging target media in the transmission direction increases than the rigidity before bending. Consequently, even though a separation imaging-target medium is bound together with a transportation imaging-target medium using a binding member, the separation imaging-target medium is transmitted to an imaging unit along with the transportation imaging-target medium by transporting rollers without bending in the transmission direction. A superimposed-transmission of the imaging target media is detected by sensors and rotation of the transmitting roller is stopped. Due to this, the superimposed-transmission of the imaging target media is stopped just before the imaging unit. | 08-27-2009 |
20090284967 | LIGHTING APPARATUS AND IMAGE READING APPARATUS - A lighting apparatus lights up a lighting target and includes a first substrate with a first LED group mounted thereon, and a second substrate with a second LED group mounted thereon. First LEDs of the first LED group and second LEDs of the second LED group are equally spaced in line and face with each other. Light beams emitted from the first LEDs and the second LEDs are reflected by reflection surfaces of the first and the second substrate as they travel toward the lighting target and gather in a space between a first protruding portion of the first substrate and a second protruding portion of the second substrate, and applied to the lighting target. | 11-19-2009 |
20100103478 | IMAGE READING APPARATUS - An image reading apparatus includes a sheet conveyance path on which a sheet of a document from which an image is to be read is conveyable; a light source that emits light to be irradiated on the sheet; a conductive unit through which heat generated at the light source is transferable; and a heat radiating unit that forms a part of the sheet conveyance path, through which the heat transferred from the light source to the conductive unit is propagable, and that radiates the heat propagated from the conductive unit to air flowing in the sheet conveyance path when the sheet is being conveyed. | 04-29-2010 |
20100110505 | ILLUMINATING DEVICE AND IMAGE READING APPARATUS - An illuminating device includes a linear light source mounted on a mounting surface of a board, with a plurality of light-emitting elements being arrayed thereon, for irradiating light toward an illuminating target, a white reflecting surface provided in a planar shape parallel to an optical axis of the linear light source on a surface including the mounting surface, to reflect the light from the linear light source, and a mirror surface formed in a planar shape that reflects the light from the linear light source and reflected light from the white reflecting surface. The linear light source, the white reflecting surface, and the mirror surface are arranged such that a third plane crosses a first plane on the illuminating target side than a second plane, and 0°<θ | 05-06-2010 |
