摘要： A sheet conveyor includes a separation roller, a retard roller forming a nip with the separation roller, and a load application device configured to apply a load to the retard roller. The load application device includes a motor, a first drive train, a second torque limiter isolated from the first drive train, and a controller. The first drive train includes a plurality of gears for transmitting a driving force from the motor to the retard roller, a first torque limiter, and a clutch disposed between the motor and the first torque limiter. The second torque limiter is configured to communicate with the retard roller. The controller is configured to, during conveyance of a sheet, control the clutch to allow transmission of the driving force from the motor for a predetermined time period and to interrupt transmission of the driving force from the motor after expiration of the predetermined time period.

摘要： A sheet feeder includes: a first roller; a separation member; a shutter; a pressing portion; and a cam portion. The separation member contacts the first roller at a contact position. An axis of the shutter is positioned downstream of the separation member in a conveying direction. The shutter is movable between first and second positions. The shutter in the first position has a portion positioned upstream of the contact position in the conveying direction. The pressing portion is positioned upstream of the separation member and the shutter in the first position in the conveying direction. The pressing portion is movable between third and fourth positions. The pressing portion in the third position faces the first roller. The pressing portion in the fourth position is separated from the first roller farther than in the third position. The cam portion is positioned upstream of the pressing portion in the conveying direction.

摘要： In an image reading apparatus, in a first process, first and second motor rotate feed and conveyance rollers with circumferential speeds of first and second speeds, respectively. In the first process, the reverse roller has a first separation performance for separating a sheet from another sheet. In a second process, after a detector detects a leading edge of the sheet, the controller stops the first motor, and decelerates the second motor, and the reverse roller has a second separation performance lower than the first separation performance. In a third process, after a trailing edge of the sheet reaches a specific position, the first motor starts rotating the feed roller with the circumferential speed of the first speed. In a fourth process, after the trailing edge of the sheet passes through a reading end position, the controller accelerates the second motor.

摘要： A feeding apparatus includes a pickup roller arranged to pick and feed a medium downstream along a conveying path, a separating roller arranged downstream to the pickup roller for advancing the medium downstream, a brake roller arranged opposite to the separating roller, and a pressing structure arranged opposite to the pickup roller and operable to swing toward or away from the pickup roller according to the rotating direction of the brake roller. When the brake roller rotates for feeding mediums downstream, the pressing structure moves toward the pickup roller and applies a normal force required for picking the medium. But when the brake roller stops rotating downstream because multiple mediums are fed between the brake roller and the separating roller, the pressing structure moves away from the pickup roller and stops applying normal force, so as to control the medium-picking process.
