Abstract: An image processing apparatus includes: a support surface configured to support a sheet, a sheet feeding roller configured to feed the sheet in a conveying direction, a separation member for separating the sheet one by one and positioned downstream of the sheet feeding roller in the conveying direction, and a regulating member displaceable between a first position where the regulating member abuts against a distal end of the sheet supported by the support surface to regulate passage of the sheet in the conveying direction between the sheet feeding roller and the separation member and a second position that is farther from a conveyance path than the first position and that allows passage of the sheet in the conveying direction. The regulating member has a wall surface that abuts against the distal end of the sheet and includes at least one protrusion on the wall surface.

Abstract: An image reading apparatus includes a housing, a transport unit, a first reader, a controller, and a positioning mechanism. The controller controls the transport unit to transport a second medium different in thickness from a first medium in a first transport direction and then in a second transport direction opposite to the first transport direction. The positioning mechanism moves the first reader from a first position to a second position by using a drive force by which the transport unit transports the second medium in the first transport direction. The positioning mechanism maintains the first reader at the second position while the second medium transported by the transport unit in the second transport direction is passing the first reader, and moves the first reader from the second position to the first position after the first reader reads the image on the first side of the second medium.

Abstract: An image reading apparatus, having a body, a feeder tray, a conveyer, a first reader, and a shifting device, is provided. The body includes a first inlet, a second inlet, and a conveyance guide. The feeder tray being at a closed position covers the first inlet and the feeder tray being at an open position exposes the first inlet. The conveyer conveys a readable medium guided by the conveyer guide. The first reader reads an image on a first side of the readable medium conveyed by the conveyer. The shifting device shifts the first reader to a first position in a case where the feeder tray moves from the closed position to the open position and to a second position in a case where the feeder tray moves from the open position to the closed position.

Abstract: 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.

Abstract: A sheet conveying apparatus, including a conveyer to convey a sheet in a predetermined conveying direction along a predetermined conveyer path, and a discharger forming a part of the conveyer to discharge the sheet from the conveyer path, is provided. The discharger includes a driving roller, a pinch roller arranged to confront the driving roller across the conveyer path, and an urging member to urge the pinch roller against the driving roller. The conveyer includes a chute member. The chute member includes a guiding face defining a part of the conveyer path, a supporting face to support one end of the urging member, and a contact face located on a particular face of the chute member opposite from the supporting face. The sheet conveying apparatus includes a plate member made of metal arranged to extend in a direction intersecting with the conveying direction and to contact the contact face.

Abstract: A sheet conveyor includes: a sheet conveyor; a supporter including a movable guide and having a first and second end portions in a widthwise direction; and a first cover adjacent to the first end portion. The supporter has an upstream edge in the conveying direction. A first-end upstream end portion of the upstream edge is nearer to the sheet conveyor than a second-end upstream end portion of the upstream edge. The first cover has a first region and a second region. The first region has a height greater than or equal to that of the guide and extends to a position located upstream of an upstream, end portion of the guide. The second region is located upstream of the first region, and the second region is less in height than the first region. The first-end upstream end portion overlaps the first region when viewed in the widthwise direction.
