| 20090067012 | IMAGE READING APPARATUS - An image reading apparatus includes an image reading unit that can move along a scanning direction, and reads primary image data from a medium arranged on a medium arrangement surface by moving the image reading unit from a home position to a sub-scanning direction. The image reading apparatus further includes a determining unit that determines the presence or absence of the medium on the medium arrangement surface based on determination image data that is different from primary image data, and read by the image reading unit at a determination position arranged between the home position and a reading-end position of the primary image data. | 03-12-2009 |
| 20090231639 | Image processor, image processing method, and computer program product - An image processor includes a control unit, wherein the control unit includes an image obtaining unit that obtains an image including a document area corresponding to a document read by an image reader, an edge coordinate detecting unit that detects coordinate values of edge candidate pixels, a tilt calculating unit that calculates a tilt of the document area, or a tilt obtaining unit that obtains the tilt of the document area detected by a predetermined sensor, an edge end coordinate extracting unit that extracts a coordinate value of an edge end candidate pixel, a straight line calculating unit that calculates a straight line corresponding to the edge, and either one or both of a tilt correcting unit that corrects the tilt of the document area by rotating the document area, and an area clipping unit that clips the document area from the image. | 09-17-2009 |
| 20090261167 | IMAGE READING APPARATUS - In an image reading apparatus, a magnetic shielding member suppresses interference of an electromagnetic wave for power supply or an electromagnetic wave for transmission and reception of ID information that would otherwise propagate to a reading unit with a carrier cable of the reading unit and the like. Thus, even if an ID-information obtaining unit obtains ID information of an electronic tag of an RFID card while an image read surface of the RFID card is being imaged by the reading unit, an influence of the electromagnetic wave for power supply, the electromagnetic wave for transmission and reception of the ID information, or both over the reading unit can be suppressed. With this, even if pickup image data representing the image read surface of the RFID card and the ID information of the electronic tag are simultaneously obtained, the obtained pickup image data representing the image read surface of the RFID card can be of high quality. | 10-22-2009 |
| 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 |
| 20100231943 | IMAGE READING APPRATUS, IMAGE READING METHOD, AND COMPUTER PROGRAM PRODUCT - An image reading apparatus includes a hopper unit, a separating unit, a reading unit, an ejecting unit, a stacking unit, a control unit, and a storage unit. The control unit includes a detecting unit that detects abnormal reading of the document read by the reading unit, an image storing unit that associates the read image and an abnormal reading result with a reading order of the document to store, a separation stacking unit that controls the ejecting unit to separate the document in which the abnormal reading is detected and the document in which the abnormal reading is not detected to eject to the stacking unit, a rereading unit that allows the reading unit to read again the document in which the abnormal reading is detected, thereby obtaining a reread image, and an image replacing unit that replaces the image corresponding to the reading order with the reread image. | 09-16-2010 |
| 20110228349 | IMAGE READING APPARATUS - An apparatus includes imaging units, each including: a light source to emit light; and an image sensor to pick up an image of a medium to be moved relatively between the imaging units. The light source of one of the imaging units is provided at a position where a direct light is guided to the image sensor of the other imaging unit, and the image sensor of the other imaging unit is configured to pick up an image for image formation when a reflected light emitted from the light source of the other imaging unit and reflected by the medium is guided to the image sensor of the other imaging unit, and to pick up an image for edge detection when the direct light is guided to the image sensor of the other imaging unit, and an edge of the medium is detected based on the image for edge detection. | 09-22-2011 |
| 20110261420 | IMAGE READING APPARATUS - An image reading apparatus includes a light source unit, an image sensor, and a light guiding unit at least including a light reflector. The light guiding unit may include a first masking shield and a second masking shield. The light source unit irradiates light toward an original. The image sensor picks up an image of the original based on reflected light of the light by the original. The light guiding unit is provided on an opposite side to the light source unit to cause a part of the light to directly enter into the image sensor, when the original is not fed to the image sensor. The light guiding unit reduces light incident to the image sensor, among the light and light having transmitted through the original, at the time of picking up the image of the original by the image sensor. | 10-27-2011 |
| 20110279840 | IMAGE READING DEVICE AND IMAGE READING METHOD - An image reading device includes a first conveying unit that sequentially feeds a plurality of media placed in a tray one by one in a conveying direction, a second conveying unit disposed downstream of the first conveying unit in the conveying direction and conveys a medium among the plurality of media fed by the first conveying unit in the conveying direction, and an imaging unit disposed downstream of the second conveying unit in the conveying direction. The imaging unit captures an image of the medium conveyed thereto and generates image data of the medium. | 11-17-2011 |
