An image processing apparatus includes a scanner configured to read an image formed on a sheet along a reading direction and generate image data thereof, and a processor. The processor is configured to select a first region of the generated image data into which a first image indicating the reading direction is to be combined, set a pixel value of the first image in accordance with a pixel value of a pixel around the first region, and combine the first image having the determined pixel value into the first region of the image data and output the combined image data.

An image reader wherein a controller executes: a start process of starting a reading operation; a head edge detection process of detecting a document width; a first side edge detection process of detecting a side edge until an occurrence of a first change from a side edge detecting state to a side edge non-detecting state; a calculation process of calculating a continuation distance based on the document width; a second side edge detection process of detecting the side edge until an occurrence of a second change from the non-detecting state to the detecting state; a third side edge detection process of detecting the side edge until an occurrence of the first change; and an end process of ending the reading operation when the second change does not occur in a continuation range in the second detection process or when the first change occurs in the third detection process.

A reading apparatus, having a document placement plate, a reader, a driving device, a cover, and a controller, is provided. The cover includes an alignment part and a protrusive part. The protrusive part includes an uneven surface and first and second edges forming outer edges of the uneven surface extending in a main scanning direction and in a sub-scanning direction, respectively. The controller is configured control the driving device to move the reader in the sub-scanning direction and the reader while being moved to read the protrusive part, and detect the first edge and the second edge in image data of the protrusive part read by the reader based on an image of the uneven surface and determine a reading range for the reader in the document placement plate based on positions of the first edge and the second edge.

A control unit of an image reading apparatus determines, based on results of detection of an original document by a plurality of second detecting units, whether the original document will pass a position at which the original document is to be detected by a first detecting unit that is located downstream of the second detecting units and upstream of a reading unit. When it is determined that the original document will not pass a position at which the original document is to be detected by the first detecting unit, the control unit determines a timing for reading the original document by using the reading unit, relative to a time point at which the original document is detected by the second detecting units. The control unit causes the reading unit to read the original document at the determined reading timing.

An image reading device includes reading devices arranged in a main scanning direction perpendicular to a sub-scanning direction, position reference members each including a reference pattern for correcting relative positions of pixels in each of the reading devices or relative positions of the reading devices, and circuitry. The reference members move in the sub-scanning direction relative to the reading devices, and include first reference members for correcting the relative positions of the reading devices and second reference members for correcting the relative positions of the pixels in each of the reading devices. While switching between the first reference members and the second reference members, the circuitry calculates a correction value for a deviation of the pixels in each of the reading devices and a correction value for a deviation of the reading devices based on a result of reading of the reference members.

A device (e.g., scanner) for handling a paper holder (binder) having an upper cover, a lower cover, and at least one paper held therein is made available, the device including a control circuit, a lifting mechanism comprising an adhesive member, and an image capturing device. The adhesive member is configured to removably attach to the upper cover of the paper holder. The lifting mechanism is configured to flip the upper cover of the binder open when the adhesive member is attached to the upper cover. The lifting mechanism is configured to detach from the binder and return to its original position after the upper cover is flipped open. The image capturing device is configured to take one or more images of the open binder after the lifting mechanism is detached from the binder and returned to its original position away from the binder after the upper cover is flipped open.

A medium transport apparatus includes a feeding section configured to nip a medium and feed the medium in a transport direction, a sensor disposed to face a side of the medium being transported in the transport direction, the sensor being configured to detect motion of the medium, and a control unit configured to stop the transport of the medium based on a detection value received from the sensor, in which during a period including a time at which a leading edge of the medium is nipped by the feeding section, the control unit continues transporting the medium irrespective of the detection value from the sensor.

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.

An image reading device includes reading devices arranged in a main scanning direction perpendicular to a sub-scanning direction, position reference members each including a reference pattern for correcting relative positions of pixels in each of the reading devices or relative positions of the reading devices, and circuitry. The reference members move in the sub-scanning direction relative to the reading devices, and include first reference members for correcting the relative positions of the reading devices and second reference members for correcting the relative positions of the pixels in each of the reading devices. While switching between the first reference members and the second reference members, the circuitry calculates a correction value for a deviation of the pixels in each of the reading devices and a correction value for a deviation of the reading devices based on a result of reading of the reference members.

A data generation system includes circuitry configured to generate data of sub-images constructing an image. Each of the sub-images includes at least one of image elements of the image. The image elements are aligned in a direction perpendicular to a given direction in which an image forming apparatus moves to form the image. The circuitry is configured to, when, in an attempt to add another one of the image elements adjacent to the at least one of the image elements in one of the sub-images, the other one of the image elements does not fit within the one of the sub-images, generate data of the one of the sub-images without the other one of the image elements.
