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.

Provided is a control unit of a conveying apparatus, the conveying apparatus including: a conveying unit that conveys recording paper along a conveying path; and an imaging unit that images the recording paper and an object not conveyed by the conveying unit, wherein the control unit acquires actual conveyance information of the recording paper from image information of the recording paper imaged by the imaging unit and image information of the object imaged by the imaging unit.

Embodiments are directed at a systems, methods, and apparatuses for automatically aligning the lead edges of a document stack loaded in a scanner system. An automated jogger system includes feeder gate elements which are driven forward and backwards in an oscillating motion. This motion causes the documents in the stack to slide between each other, causing the documents to move and rotate towards the feeder gate elements, aligning the lead edges of the stack prior to being fed into the document scanner.

A medium feeding device includes: a medium mounting section onto which a medium to be fed is mounted; a feeding unit that feeds the medium mounted on the medium mounting section; and a supporting member that supports an end in a width direction of the medium mounted on the medium mounting section and that supports the medium at a higher position than the medium mounting section in a direction of loading of the medium, the width direction being a direction crossing a feed direction.

A medium discharge device includes a discharge roller pair that is provided with a discharge driving roller and a discharge driven roller which drivably rotates in contact with the discharge driving roller, and a medium receiving tray which receives the medium that is fed and discharged by the discharge roller pair, in which the medium receiving tray includes a guide member which guides such that a tip end of the medium which is discharged from the discharge roller pair enters the medium mounting surface at a predetermined angle, and the guide member is provided to be elastically displaceable in an advancing and retreating direction with respect to the medium mounting surface of the medium receiving tray and is displaced in a direction coming close to the medium mounting surface according to raising of a pressing load due to the medium that is discharged to the medium receiving tray.

A sheet conveyance apparatus includes a drive transmission mechanism configured to transmit a driving force from a driving source to a rotary conveyance member. The drive transmission mechanism includes a shaft, a first rotary member supported on the shaft and configured to rotate by being driven by the driving source, a second rotary member supported on the shaft and configured to rotate the rotary conveyance member, a drive transmission member provided movably in an axial direction of the shaft, and configured to transmit the driving force between the first rotary member and the second rotary member, and a moving unit configured to move the drive transmission member to a transmission position and a release position. The drive transmission member engages the first and second rotary members with each other at the transmission position, and releases engagement of the first and second rotary members at the release position.

An image forming device with a collapsible paper guide is provided. The image forming device includes a casing, a first tray structure and a paper guide. A medium gateway opening is formed on the casing. The first tray structure is disposed on the casing and adjacent to the medium gateway opening. The paper guide includes a first base disposed on the first tray structure and a first guiding component pivotally connected to the first base. The paper guide is switchable relative to the first tray structure between a used position and a stored position. A first included angle included between the first guiding component and the first base is less than 90 degrees when the paper guide is located at the used position, so that the first guiding component can be interfered and driven to pivotally fold for preventing the paper guide from being broken or damaged.

A medium ejecting apparatus includes an ejection roller to eject medium, a first tray to place the medium ejected by the ejection roller, a second tray provided so as to be pulled out from the first tray, and a stopper accommodated in the first tray together with the second tray in a laid state, rotatably supported at a downstream end portion in a medium ejecting direction of the second tray, and provided with a slid portion. The first tray is provided with a sliding portion to slide with respect to the slid portion in response to an operation in which the second tray is pulled out from the first tray to raise the stopper.

A medium conveying apparatus includes a housing including an accommodation portion provided with a guide portion at an end portion in a width direction, a tray accommodated in the accommodation portion so as to be pulled out, and including a placing surface for placing an ejected medium, and an engaging portion provided on a side surface of the tray, to engage the guide portion. The guide portion includes a pair of rails inclined upward and having a predetermined width. The engaging portion includes two protrusions provided so as to slide between the pair of rails and located apart from each other by a predetermined distance. By locating the two protrusions between the pair of rails, the tray is positioned at a predetermined position with respect to the housing with a front end portion of a downstream side in the medium ejecting direction located upward.

A conveying device conveys a sheet selectively along a first conveying path and a second conveying path which are connected at a junction into a common path portion. A reading unit reads an image of a sheet conveyed in the common path portion. A shutter is disposed in the second conveying path at a position upstream of the junction in a sheet conveying direction. The shutter is movable between a first position and a second position. The actuator is disposed in the common path portion and movable between a third position and a fourth position in response to the shutter moving between the first position and the second position, respectively. In a case where a detection sensor detects that the actuator is at the fourth position, a controller controls the conveying device to convey the sheet along the second conveying path.
