A reading device is configured to detect an edge position of a target object to be conveyed in a conveyance direction. The edge position is a position of an edge of the object in a width direction intersecting the conveyance direction. The reading device includes a sensor device, an adder, and an edge position detector. The sensor device includes a pixel array including a plurality of elements arranged in the width direction. The adder is configured to add detection signals output from the elements at respective positions in the width direction. The edge position detector is configured to detect the edge position on basis of a position at which an output of the adder changes to a value larger than a threshold. Each element is configured to output a detection signal based on a reception amount of light in one of different wavelength bands.

An image reading apparatus includes an optical unit through which a light from a document passes, an image sensor configured to receive the light from the document via the optical unit, and a first holding member configured to hold the optical unit and the image sensor. The first holding member has an opening and a second holding member is fitted in the opening. The optical unit is disposed on the second holding member and the second holding member is positioned with respect to the first holding member with a gap between the first holding member and the second holding member and fixed to the first holding member by an adhesive that fills the gap.

An image processing apparatus includes a document area extracting module configured to extract a document area from the captured image, the document area being an area of the document, a note area extracting module configured to extract a first note area from the captured image, the first note area being an area of the first note positioned at a first position of the document area of the first page, a character determining module configured to determine the first character included in the first note area by optical character recognition, a document image generating module configured to mask the first note area included in the document area, and generate a document image, a file name generating module configured to generate a file name including the first character, and a file generating module configured to generate an electronic file of the document image having the file name.

Provided are systems and methods for identifying, isolating, and/or aligning sheets. An identification system can facilitate accurate identification of a sheet by (i) vacating one or more components of the system that are not the sheet from a zone of detection, and/or (ii) determining a reference axis of the sheet. An isolation system can facilitate accurate isolation of a sheet by (i) providing targeted air flow, and/or (ii) introducing a wave into the sheet. Identification systems and/or isolation systems described herein may facilitate isolation of sheets that were previously fastened together by one or more fasteners. An alignment system can facilitate accurate alignment of a first sheet at an upstream location relative to a second sheet at a downstream location via machine learning.

Systems and methods are provided for processing and extracting content from an image captured using a mobile device. In one embodiment, an image is captured by a mobile device and corrected to improve the quality of the image. The corrected image is then further processed by adjusting the image, identifying the format and layout of the document, binarizing the image and extracting the content using optical character recognition (OCR). Multiple methods of image adjusting may be implemented to accurately assess features of the document, and a secondary layout identification process may be performed to ensure that the content being extracted is properly classified.

An election voting system is provided. The election voting system includes a printer for accepting printer medium. In one embodiment, the printer medium may be a paper printer medium. The printer medium includes mark(s) positioned on the printer medium that may be utilized to determine whether the printer medium is inserted into the printer in the proper orientation. The election voting system may include a sensor that identifies the presence of the mark. Two marks are positioned so that the orientation of the paper (right side up versus upside down) can be determined. In addition, in one embodiment, the marks are positioned so that even if the printer medium is rotated 180 degrees, orientation as to which side is up may be detected.

A sheet identification device includes a light irradiation portion. When forming an identification image, the light irradiation portion projects first pattern light (P11) and second pattern light (P12) having different dependences on a fiber direction of a surface of a sheet on an identification region (R1). The identification image is an image of the identification region (R1) of the surface of the sheet on which image formation or image reading is performed, which is used for identifying the fiber direction of the surface of the sheet.

A medium transporting apparatus includes a first medium transport path in which a transport roller pair is provided, a second medium transport path for feeding a medium fed downstream in a medium transport direction from the transport roller pair to an upstream position of the transport roller pair in the first medium transport path, and a medium detection unit for detecting passage of a medium in the first medium transport path, in which a position at which the medium detection unit detects a medium is switched between a transport direction upstream position and a transport direction downstream position of the transport roller pair according to whether or not a medium is transported on the second medium transport path.

A movement amount detecting device performs discrete Fourier transform onto N-th image data and N+1-th image data, thereby generating N-th wave number space data and N+1-th wave number space data. The movement amount detecting device obtains a target speed of a sheet, and determines a cutoff value based on the obtained target speed and an exposure time in an image sensor. The movement amount detecting device calculates an amount of movement of the sheet based on a phase difference between the N-th wave number space data and the N+1-th wave number space data in a wave number component smaller than the cutoff value.

A control method in a printing apparatus includes printing, by a printing unit, an adjustment image for adjusting a printing position on a sheet, conveying, by a conveying unit, the sheet on which the adjustment image is printed, reading, by a reading unit, an image to generate image data, the reading unit being executable to perform reading by a first reading method for reading an image of a sheet without conveying the sheet or a second reading method for reading the image of the sheet while conveying the sheet, and determining, based on that a type of the sheet on which the adjustment image is to be printed is a specific type, to read the adjustment image by the first reading method.
