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.

An image reading apparatus includes a first posture detection unit that detects a first posture that is a posture of the apparatus main body when not in use, a second posture detection unit that detects a second posture that is a posture of the apparatus main body when in use, and a posture change detection unit that detects a change in a posture of the apparatus main body. When the first posture detection unit detects a switchover of the apparatus main body to the first posture in a first power supply mode in which power is supplied to the first posture detection unit, the second posture detection unit, and the posture change detection unit, the first power supply mode transitions to the second power supply mode in which a controller supplies power to only the posture change detection unit.

An image signal processing device includes a reference signal generating portion, a determination portion, and an extraction portion. The reference signal generating portion generates and outputs a reference signal that sequentially transmits reference pulses shifted from horizontal synchronization pulses on a horizontal synchronization signal by a predetermined shift time. The determination portion determines whether the horizontal synchronization pulses are normal by comparing time differences between input of the horizontal synchronization pulses and input of the reference pulses with the shift time. The extraction portion extracts line image data points from an image signal in synchronization with the input of the horizontal synchronization pulses that have been determined as normal.

The data input support apparatus in the present disclosure acquires item information relating to a combination of an item name and an item value described in a business form image based on character recognition results of the business form image, and displays an item value display area and an image preview display area having an overview image display area and an enlarged image display area. The item value display area displays an item value of an item name corresponding to a specific item type from the item information. The overview image display area displays the entire business form image or an overview image in which the displayed item value and the item name are highlighted. The enlarged image display area displays an enlarged image including the displayed item value. The display unit switches and displays display contents in the image preview display area in accordance with the acquired item information.

There is provided an information processing apparatus configured to obtain criterion data, which is reference image data, by executing a adjustment parameter determining program, obtain evaluation data which is image data scanned by a scanner, generate a plurality of pieces of comparison data by adjusting the evaluating data using a plurality of adjustment parameters different from each other, respectively, associate each comparison data with an adjustment parameter used to generate the comparison data, and display the criterion data and the plurality of pieces of comparison data in a list. When a selecting operation of selecting one from the plurality of pieces of comparison data is performed, the information processing apparatus determines an adjustment parameter for the scanner based on the adjustment parameter associated with the selected comparison data.

An image reading device includes a plurality of readers, an access opening, and a lift. The plurality of readers read an image on a recording medium. The plurality of readers are arranged around a carrier to rotate while carrying the recording medium on a peripheral surface of the carrier. The plurality of readers are arranged radially about a rotation axis of the carrier. The plurality of readers are to be introduced through the access opening. The lift includes a cable to lift one reader of the plurality of readers introduced through the access opening. The lift lifts and locates the one reader at a predetermined height position around the carrier with the cable.

An image forming apparatus includes a light scanning device, a developing portion, a control portion and a storage portion. The storage portion stores an evaluation chart. The evaluation chart includes a first evaluation pattern and a second evaluation pattern. The first evaluation pattern includes a first patch row. The first patch row is formed by arranging a plurality of first evaluation patches. The first evaluation patch includes a first dot row, a second dot row and an auxiliary dot row. The second evaluation pattern includes a second patch row. The second patch row is formed by arranging a plurality of second evaluation patches.
