Medium transport device and image reading apparatus
A medium transport device includes a feeding roller which sends a medium to a downstream side; and a detecting unit which can detect the medium sent by the feeding roller at a predetermined position on a transport path, in which the detecting unit includes a lever member of which a posture is changed when being in contact with the medium, and a detecting portion which detects a change in posture of the lever member, and the lever member applies an external force which causes at least a part of the medium to be bent in a gravity direction by being in contact with the medium in a predetermined posture.

Sheet feed device, image forming apparatus, and method for controlling sheet feed device
In a case where, for example, a certain sheet feeding operation by one of sheet delivery portions is an operation that continues from a sheet feeding operation by another one of the sheet delivery portions in a sheet feed device, a control portion delays output timing, to a feed clutch, of a control signal for feeding a first one of recording sheets, as compared to output timing of control signals for sequentially feeding a second and the following ones of the recording sheets from the same sheet delivery portion.

Sheet feeder that ensures execution of sheet feeding with more certainty by feeding retry process and image processing apparatus including the same
A sheet feeder includes a sheet platen, a pickup roller, a feeding roller, a regulating portion, a driving mechanism, a feeding control unit, a sheet sensor, and a determination processing unit. The feeding control unit executes a feeding operation by rotationally driving the pickup roller and the feeding roller in a state where the regulating portion is located at a retreating position. The sheet sensor is located at a downstream side in the feeding direction of the feeding roller. The determination processing unit determines whether the sheet feeding has succeeded or not based on a signal from the sheet sensor. After a start of the feeding operation, when the determination processing unit determines that the sheet feeding has failed, the feeding control unit once moves the regulating portion located at the retreating position to the abutting position and then executes the feeding operation again.
SHEET CONVEYING APPARATUS
A sheet conveying apparatus includes: a supporter having a support surface; a supplier including a supply roller rotatable about a rotation axis; a separator for separating sheets; a stopper pivotable about a first axis and movable between a first position at which a distal end portion of the stopper intersects a conveyance path and a second position at which the distal end portion is separated from the support surface; and a stopper cam pivotable about a second axis and movable between a third position at which the stopper cam contacts the distal end portion at the first position and a fourth position at which the stopper cam is spaced apart from the distal end portion at the first position. The second axis is located upstream of the rotation axis of the supply roller and farther from the support surface than the rotation axis.
HIGH SPEED AUTOMATED FEEDING SYSTEM AND METHODS OF USING THE SAME
Disclosed is an automated insert feeding system and related methods, capable of removing bulk-packaged items from a tray or other package, and separating the bulk-packaged items individually for distribution into individual packages in high speed reliable fashion. The disclosed systems can also be loaded with multiple packages of the pre-packaged items for automatic feeding into the system which allows human operators to load several packages and allow the system to work unattended, thereby reducing man-hours spend on the process.

SHEET CONVEYING APPARATUS
A sheet conveying apparatus includes: a supporter having a support surface configured to support sheets; a supplier having a conveying surface exposed from the support surface and moved to supply one or more sheets; a separator including a separating roller and a retard roller located downstream of the supplier; and an inclined surface disposed upstream of the nip position and pivotable about a pivot axis. The inclined surface has a first end portion and a second end portion, and the second end portion is located downstream of the first end portion. The inclined surface is inclined such that the second end portion is nearer to the support surface than the first end portion. The first end portion is located upstream of a downstream end portion of the conveying surface. The second end portion is spaced apart from the conveying surface.
