摘要： When a size of a document is not specified, a control unit of an image reading device identifies, for image data generated as a reading result by a reading unit, a region of the document by detecting an edge of the document. When the size of the document is specified, the control unit searches the image data, at a position within a first range including a position away from an origin by a first distance, for a downstream end of the document from a downstream end of the image data toward upstream in a transport direction, and based on a position of the downstream end of the document identified by the searching, identifies as a region of the document a region corresponding to the size of the document specified.

摘要： An image reading apparatus includes a document transport path along which a document is transported, a feeding roller that is provided on the document transport path and that feeds the document, and a reader that is provided downstream of the feeding roller in the document transport path and that reads the document, in which a main board on which electronic components are mounted, when viewed from a width direction, which is a direction intersecting a document transport direction, is disposed in a region between the document transport path and a feeding roller tangent line, which is a straight line parallel to the document transport path and which is in contact with the feeding roller at a position separated from the document transport path. In addition, the main board may be provided in an orientation along the document transport path.

摘要： A detection section that detects a value used for determining whether or not a jam of a paper sheet has occurred includes a sound detection unit that detects a sound and an auxiliary detection unit that detects a value different from the magnitude of a sound in the case where a jam of the paper sheet has occurred, and, in the case where the sound detection unit has detected a sound of a magnitude equal to or greater than a first threshold value, a control unit controls determines whether or not a jam of the paper sheet has occurred with reference to a detection result of the auxiliary detection unit, and controls a transport unit on the basis of a result of the determination.

摘要： An image reading apparatus includes a transport unit which transports a document, and reading units which read an image of the document which is transported. It is assumed that an operation of reading an image when specific setting information is not input to a control device of the image reading apparatus is set to a first reading mode, and an operation of reading an image when specific setting information is input to the control device is set to a second reading mode. In this case, in the second reading mode, image data of an image with a resolution which is equal to that in the first reading mode is generated, while causing the reading units to read an image from a document which is transported by the transport device at a lower speed than that in the first reading mode.

摘要： A scanner includes an apparatus main body, a stand, and a switching mechanism. The apparatus main body includes a transport unit that transports a document along a transport path, and a reading unit that reads an image of the document. The stand supports the apparatus main body. The switching mechanism switches the posture of the apparatus main body with respect to the stand so that the transport path extends along an intersecting direction intersecting an installation surface. The switching mechanism includes a switching motor that imparts a driving force to the apparatus main body when switching the posture. The switching motor is located inside the apparatus main body on the lower side of the transport path in the vertical direction.

摘要： An image reading apparatus includes a separating roller that is capable of switching between a separation state in which an original document is separated and a non-separation state in which the original document is not separated, and determines whether or not the original document is fed in the separation state or the non-separation state based on the types of the original document set through a user interface for instructing a select of the types of the original document to be read and a start of reading the original document.
