A scanning apparatus for scanning an object includes a frame and a scanning unit. The frame defines a passage and two frame openings. The passage has two passage openings opposite to each other in a first direction. The frame openings are opposite to each other in a second direction transverse to the first direction, and are in spatial communication with the passage. The scanning unit includes at least one scanning device that includes a scanning casing and a scanner. The scanning casing has a scanning opening in direct connection with one of the frame openings of the frame. The scanner is disposed in the scanning casing, and operable to scan the object via the scanning opening when the object is moving through the passage in the first direction.

Disclosed is an imaging system, which may include: an image forming apparatus including a conveyer, a sheet feeder on which recording media are exposed to an outside, a first hardware processor that causes the conveyer to convey the recording media one by one, an image former, and a first communicator; and an imaging apparatus including an imager, a second hardware processor that causes the imager to image documents one by one in accordance with a timing at which the conveyer conveys each document, the plurality of documents being the plurality of recording media loaded on the sheet feeder to be imaged, and a second communicator that communicates with the first communicator. The imaging system performs: transmission of first information for determining an imaging timing from the first communicator to the second communicator; and/or transmission of second information for determining a conveyance start timing from the second communicator to the first communicator.

A feeding device includes a suction feeding unit having a belt for feeding a sheet in a suction state and a belt driving unit, a sheet detection sensor, and a control unit. The control unit controls the belt drive unit so as to feed the sheet in a feeding direction at a first speed. If the sheet does not arrive at the sheet detection sensor, the control unit controls the belt drive unit so as to execute a low-speed feeding of moving the belt in the feeding direction at a second speed lower than the first speed or so as to execute a reverse feeding of moving the belt in a reverse feeding direction opposite to the feeding direction.

A scanning apparatus for scanning an object includes a frame and a scanning unit. The frame defines a passage and two frame openings. The passage has two passage openings opposite to each other in a first direction. The frame openings are opposite to each other in a second direction transverse to the first direction, and are in spatial communication with the passage. The scanning unit includes at least one scanning device that includes a scanning casing and a scanner. The scanning casing has a scanning opening in direct connection with one of the frame openings of the frame. The scanner is disposed in the scanning casing, and operable to scan the object via the scanning opening when the object is moving through the passage in the first direction.

Systems and methods are provided for document handling. Non-vision detection systems may be capable of detecting the dimensions, orientation, and/or position of a single sheet, or multiple stacked sheets. A document scanning arrangement may be capable of double sided scanning for sheets with various characteristics. The systems and methods provided may accommodate high throughput and rapid digitization of various types of documents, at a high quality.

An operation unit is provided on a front side of the image forming apparatus. A document feeding portion feeds a document supported by a document supporting portion in a document feeding direction from a front side of the image forming apparatus toward the rear side of the image forming apparatus. A document discharge portion discharges the document in a document discharge direction from the rear side toward the front side. The operation unit is disposed on one side with respect to an apparatus center of the image forming apparatus in a left-right direction orthogonal to a direction from the front side to the rear side. A conveyance center of the document feeding portion in the left-right direction is disposed on the other side with respect to the apparatus center in the left-right direction.

A recording apparatus includes a support unit including a support surface configured to support a medium, a recording unit configured to perform recording on the medium supported by the support unit, and a projection unit configured to project an image onto the support surface. The projection unit includes an irradiation unit configured to irradiate the support surface with light, and a light blocking portion configured to block a part of the light emitted from the irradiation unit. The light blocking portion includes at least one light blocking region configured to block the part of the light emitted from the irradiation unit. The projection unit is configured to project a reference position image indicating a reference position of the medium supported by the support surface onto the support surface by blocking the part of the light emitted by the irradiation unit with the at least one light blocking region.

An edge detection unit is arranged in a conveying portion conveying a sheet and detects the edge of the sheet in the width direction perpendicular to the sheet conveying direction. A light source unit is arranged opposite the sheet. A detecting portion holder holds the edge detection unit and the light source unit. A conveying roller pair positions the sheet conveyed toward the edge detection unit. A unit housing houses the detecting portion holder and the conveying roller pair. The edge detection unit has a contact glass making contact with the sheet. The light source unit has a facing glass facing the contact glass. One glass out of the contact glass and the facing glass is inclined downward at a first angle with respect to the tangent line, which passes through the nip portion between the conveying roller pair, toward the downstream side in the sheet conveying direction.

A medium feeder includes a feed roller that feeds a medium loaded on a medium loading section; a transport roller disposed downstream relative to the feed roller; a first driving source that drives at least the feed roller; a second driving source that drives at least the transport roller; and a housing that houses the feed roller, the transport roller, the first driving source, and the second driving source, wherein the housing includes a lower unit that constitutes a lower part of the housing, and an upper unit openable relative to the lower unit, and the first driving source and the second driving source are disposed on both sides relative to a center part of the lower unit in a width direction perpendicular to a medium transportation direction.

In an image forming apparatus, a first motor causes a first rotor to rotate. The first motor rotates based on a first drive signal. A second motor causes a second rotor to rotate. The second motor rotates based on a second drive signal. A reading unit is provided between the first rotor and the second rotor. Based on a read signal, the reading unit reads a paper sheet being conveyed line by line. In a first period, a read signal generation unit generates the read signal in accordance with a frequency of the first drive signal. In a second period, the read signal generation unit generates, as the read signal, a signal for reading the paper sheet being conveyed at a reference speed.
