There is provided an image reading apparatus in which a low output mode is a mode that can be controlled in a coupling state where a low power-feeding USB device is coupled, a high output mode is a mode that can be controlled in a coupling state where a high power-feeding USB device capable of feeding power higher than the low power-feeding USB device is coupled, and a control section does not perform image reading at a second reading speed faster than a first reading speed and performs image reading at the first reading speed in the low output mode.

Image reading apparatus and control method of image reading apparatus for controlling output modes and image reading speed

An image reading apparatus includes a reading module provided with reading elements arranged in a direction of arrangement intersecting a direction of transportation of an original copy, and configured to read an image on the transported original copy. The apparatus also includes a background plate provided with a white background portion for shading correction, and a black background portion for cutting out the original copy and having lower brightness than brightness of the white background portion. An area of the black background portion is larger than an area of the white background portion, and the white background portion and the black background portion are arranged in the direction of arrangement.

Image reading apparatus and method of creating correction data

When a device main body acquires detection information corresponding to a second original document from a rigidity detecting unit in a state where the device main body is in a first posture, a control unit of an image reading device performs a first step of stopping transporting an original document and a second step of controlling a driving source to switch the posture of the device main body from a first posture to a second posture in which a sloped angle of the device main body is smaller than that in the first posture.

In a scanner, a medium transport apparatus includes an apparatus main body including a medium transport path from a supply unit, which supplies a medium, to a discharge unit, which discharges the medium, a switcher that switches an attitude of the apparatus main body with respect to a mounting surface on which the apparatus main body is mounted, and a controller that, when the attitude of the apparatus main body with respect to the mounting surface is switched, performs control in accordance with the attitude after the switching.

Medium transport apparatus and image reading apparatus

An image reading apparatus includes a reading unit, a transport unit that transport a document, a feeding unit that transports the document to the transport unit, a controller that stops the feeding operation of the feeding unit after the leading end of the preceding document transported from the feeding unit reaches the transport unit and restarts the feeding operation after the rear end of the preceding document passes a predetermined position. The controller, restarts the feeding operation a first time after the rear end of the succeeding document following the preceding document passes the predetermined position when a size of the preceding document indicates a first size, and restarts the feeding operation a second time after the rear end of the succeeding document passes the predetermined position where the second time is longer than the first time when the size indicates a second size larger than the first size.

Image reading apparatus and control method thereof

A medium transport apparatus includes: a feed unit feeds a medium to a transport direction; a first detection unit disposed upstream of the feed unit, and detects movement of the fed medium; a second detection unit disposed downstream of the first detection unit and detects an inclination of the medium; and a control unit detects the inclination of the medium based on a signal of the second detection unit and stop transfer of the medium when the inclination exceeds a threshold value, and the plurality of the threshold values have a relationship such that when a medium length in the transport direction is a second length being shorter than a first length, a relatively higher value is produced than in a case in which the medium length is the first length, and the control unit selects a threshold value based on a detection value of the first detection unit.

Medium transport apparatus, image reading apparatus, and transport control method

The image reading apparatus includes a reading unit, a reading region in which a first region in which a member that suppresses entry of external light is disposed and a second region other than the first region are arranged in a main scanning direction of the reading unit, and a controller, wherein the controller calculates intensity of external light in the second region based on a reading value in the reading region, wherein the reading value is obtained by the reading unit, determines whether the intensity of the external light exceeds a threshold value, performs a first shading correction on a reading value of a document transported to the reading region when the intensity of the external light exceeds the threshold value, and performs a second shading correction on the reading value of the document when the intensity of the external light does not exceed the threshold value.

Image reading apparatus and shading correction method for switching shading correction based on external light

An image reading apparatus includes a reading section that receives light input via a transparent member to perform reading, a background section configured to switch a background facing the transparent member either to a first background that is a background of a first color or to a second background that is a background of a second color brighter than the first color, and a control section. The control section compares, with a threshold set in advance, first read data generated by causing the reading section to perform reading of the first background, compares, with the threshold, second read data generated by causing the reading section to perform reading of the second background, and, when the first read data is above the threshold or when the second read data is below the threshold, determines that dirt is present on the transparent member.
