  • Patent number: 10356269
    Abstract: An image reading apparatus includes a reading unit, which includes an illumination portion for irradiating an original placed on an original table with light and a light receiving portion for receiving irradiated light reflected from the original. The image reading apparatus reads the original one line at a time in a main scanning direction according to the received reflected light. The image reading apparatus determines the size of the original based on the reading result of the reading unit. The image reading apparatus shortens, in a case where the platen cover is in an open state, the lighting duration of the illumination portion than the duration where the platen cover is in a close state.

  • Publication number: 20180309894
    Abstract: An image reading apparatus includes: a reading unit, which is configured to read an original placed on an original table in a main scanning direction by irradiating the original with light; and a sub-scanning size detector, which is configured to detect presence or absence of the original on the original table by radiating invisible rays. When the platen cover forms an angle of equal to or smaller than a first angle with respect to the original table, the image reading apparatus determines a size of the original in a sub-scanning direction in accordance with a detection result acquired from the sub-scanning size detector. When the platen cover forms an angle equal to or smaller than a second angle, which is smaller than the first angle, with respect to the original table, the image reading apparatus determines a size of the original in the main scanning direction.

  • Publication number: 20180176401
    Abstract: Provided is an image reading apparatus, including: a reading unit configured to read an original image of an original placed on an original table for each line in a main scanning direction; and a control unit. The control unit is configured to derive, from the original image read for a predetermined number of lines by the reading unit, a luminance difference value between luminance values of two pixels each separated by a first distance from a pixel of interest that is located at a predetermined position in the main scanning direction, and a difference value between a maximum luminance value and a minimum luminance value of pixels within a range of a second distance, which is larger than the first distance, from the pixel of interest.

  • Publication number: 20180176407
    Abstract: An image reading apparatus compares a difference in luminance value between a pixel of interest in image information acquired via a reading unit and a pixel separated from the pixel of interest by a first distance with a first threshold value. Further, the image reading apparatus compares a difference in luminance value between the pixel of interest and a pixel present within a range to a pixel separated from the pixel of interest by a second distance that is larger than the first distance with a second threshold value. The image reading apparatus determines whether or not the pixel of interest is an edge pixel at an original end portion based on results of those comparisons, and determines an original size based on a result of the determination.

  • Publication number: 20180176400
    Abstract: An image reading apparatus includes an original table on which an original is to be placed, an original pressing member configured to press the placed original toward the original table, a reading unit configured to read light reflected from the original in a plurality of colors while irradiating the original placed on the original table with light and moving a reading position in a predetermined direction, and a storage unit configured to store color data of the original pressing member. The image reading apparatus determines whether or not the original is protruding from the original table based on output values of the plurality of colors, which are read by the reading unit in a region outside a maximum standard size of the original in a direction intersecting with a direction in which the reading unit is moved, and on the color data of the original pressing member.

  • Patent number: 4817121
    Abstract: An apparatus for checking baggage with X-rays utilizing an X-ray source for irradiating X-rays toward an object to be checked on a conveyor with a fan-shaped beam, an X-ray detector including a plurality of detecting elements aligned along each of two arms of an L-shape arranged so that one arm extends substantially parallel and another arm extends substantially perpendicularly to a conveying surface of the conveyor means with the detecting elements providing electrical signals in proportion to intensity of the detected X-rays passed by the through the object as measured data, and a picture processor for converting the measured data into a picture signal for display on a display device. The picture processor includes a distortion correcting circuit for processing the measured data from the L-shaped X-ray detector so that the measured data corresponds to data obtained by detecting elements arranged along one straight line.
