An image reading apparatus includes a medium mounting portion configured to mount a medium; a feeding means configured to feed a medium from the medium mounting portion; at least one edge guide each configured to regulate a corresponding one of at least one medium width direction edge of the medium having been mounted on the medium mounting portion; a reading means configured to read the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction; and at least one medium detection means configured to detect the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction and further outside in the medium width direction than at least one edge regulation position for the edge regulation by the at least one edge guide.

An image reading apparatus including: an angle detector configured to detect a first state in which a pressure plate is at a first angle with respect to a transparent member and a second state in which the pressure plate is at a second angle smaller than the first angle; a size determiner configured to determine a size of the original in a main scanning direction based on a reading result of a reader; and a controller configured to switch a first size determination mode in which a light source is turned on when a waiting state in which an angle of the pressure plate is larger than the first angle is changed to the first state, and a second size determination mode in which the light source is tuned on when the first state is changed to the second state.

An image reading device includes a background member, an illumination unit opposed to the background member, and a reader. The illumination unit emits light to a recording medium having an image thereon. The reader receives a reflection from the recording medium to read the image. The background member has a facing surface that faces the recording medium. The facing surface includes a reference portion on a center portion in a width direction of the background member. The reference portion has a higher reflectance than an end portion of the facing surface in the width direction.

An image reading apparatus determines an inclination amount corresponding to an inclination angle of a leading edge of an original document in a conveyance direction, and determines the length of the original document in the conveyance direction. The image reading apparatus sets a first value as a set value in a case that the length of the original document is a first length and sets a second value larger than the first value as the set value in a case that the length of the original document is a second length shorter than the first length. If the inclination amount is smaller than the set value, inclination correction for correcting the image represented by the image data is performed such that the inclination amount is reduced, and if the inclination amount is larger than the set value, the inclination correction is not performed.

An image forming apparatus includes an image forming unit, an output unit, a light source, and a processor. The image forming unit creates a printed material by forming an image on paper. The output unit outputs the printed material to an output tray. The light source is provided such that lit light is viewable from outside the image forming apparatus. The processor is configured to receive a print job for creating the printed material by the image forming unit, and perform control such that the light source is lit in a first lighting pattern in a case where a printed material of a print job for a single user has been output to the output tray and the light source is lit in a second lighting pattern in a case where printed materials of print jobs for multiple users have been output to the output tray.

Method and systems of automated document processing described herein include activating in sequence a plurality of illumination modules of an illumination source to illuminate a document, where the plurality of illumination modules are located at different positions relative to the document. The document can be imaged each time the document is illuminated by an illumination module to provide a plurality of images. A shadow profile of the document can be obtained based on the plurality of images. One or more of a boundary of the document and presence of a fastener attached to the document can be identified using the shadow profile. Any fasteners present may be removed using a robot arm.

An image reading apparatus includes a first conveyance path, a second conveyance path, an insertion/discharge port, an image reader that reads an image on a medium conveyed along the first conveyance path, and a switch that is located at a first position or a second position, wherein the switch disconnects the first conveyance path from the second conveyance path and connects the insertion/discharge port and the first conveyance path when the switch is located at the first position, and disconnects the insertion/discharge port from the first conveyance path and connects the first conveyance path and the second conveyance path when the switch is located at the second position.

An image forming apparatus includes an exit tray, a displacing mechanism, and a controller. A sheet is ejected on the exit tray. The displacing mechanism displaces a position of the sheet on the exit tray. The controller controls the displacing mechanism. The controller determines whether the sheet is a valid sheet that meets a predetermined condition or an invalid sheet that does not meet the predetermined condition. The controller controls the displacing mechanism so that a position of the valid sheet differs from a position of the invalid sheet on the exit tray.

An image reading apparatus includes: a reading unit, which is configured to read an original placed on an original table in a main scanning direction by irradiating the original with light; and a sub-scanning size detector, which is configured to detect presence or absence of the original on the original table by radiating invisible rays. When the platen cover forms an angle of equal to or smaller than a first angle with respect to the original table, the image reading apparatus determines a size of the original in a sub-scanning direction in accordance with a detection result acquired from the sub-scanning size detector. When the platen cover forms an angle equal to or smaller than a second angle, which is smaller than the first angle, with respect to the original table, the image reading apparatus determines a size of the original in the main scanning direction.
