A medium conveyance device includes a first separator that separates a first medium from a plurality of mediums, a processor that processes the first medium and sends the processed first medium as a second medium, a second separator that when a non-separation mode is set, conveys the second medium to a next processor, and when a separation mode is set, conveys a third medium, which is separated from the second medium, to the next processor, and a controller that switches between the non-separation mode and the separation mode based on information obtained as a result of processing the first medium.

A sheet conveyer having a sheet tray, a tray-driving mechanism, a conveyance guide, a feed roller, a separator, a conveyer, a conveyer-driving mechanism, a controller, and a sheet sensor to detect sheets on the sheet tray, is provided. The conveyer-driving mechanism includes a transmission-active portion and a transmission-passive portion. A conveying velocity to convey the sheets by the conveyer is higher than a conveying velocity to convey the sheets by the feed roller and the separator. The transmission-active portion and the transmission-passive portion are rotatable about a transmission axis. The transmission-passive portion rotates passively by being pushed by the transmission-active portion. After the sheet sensor detects absence of the sheets, and before the transmission-passive portion starts rotating passively, the controller conducts a specific action to move the sheet tray downward by controlling the tray-driving mechanism.

According to aspects of the present disclosures, when a cancel command is input during a document conveying process, drive of a conveying motor is stopped. Then, a movable plate of a feed tray is moved down from a supplying position to a lowermost position being a non-supplying position, and the drive of the conveying motor is restarted. The conveying motor is driven at least until a document sheet is discharged from a conveying path.

In a case where feeding of a subsequent sheet by a feed roller is started after the trailing edge of a preceding sheet is detected by a post-registration sensor, a control unit of a sheet feeder controls the feed roller to rotate at a first feeding speed, and in a case where the leading edge of the subsequent sheet has passed through a nip position between the feed roller and a separation roller, the control unit controls the feed roller to rotate at a second feeding speed.

An image forming apparatus includes a stacking portion, a pickup roller, a motor, an image forming unit, and a controller. Upon receiving an instruction for starting a first image forming job, the controller performs an initial operation of supplying current to a motor winding of the motor in a stop state and determining a phase of the rotor based on the flowing current. Based on the determined phase, the controller supplies current to rotate the rotor from its stop state and holds the rotor at a first phase when the first job ends. Upon receiving start instructions for a second image forming job within a period until a predetermined time elapses from when the rotor is held at the first phase, the controller rotates the rotor without performing the initial operation. The controller stops supplying current to the winding if no instructions are not received for starting the second job.

A document feeder includes a lift plate, a pickup roller, a lift motor, a retard roller, and a control unit. In a manual feed mode, the control unit rotates the retard roller to feed a document in a document conveyance direction. Further, the control unit causes the lift motor to start lowering the lift plate while the pickup roller is feeding a document after the rotation of the pickup roller is started.

A sheet containing apparatus includes a first container unit that contains a sheet having a first size and that tilts with respect to a horizontal direction such that a first end and a second end in a width direction of the apparatus are located at different heights with the first container unit installed in a sheet containing apparatus body when viewed in a first direction, and a covering portion that is movable to a covering position at which the covering portion covers at least a part of the first container unit in the first direction and an open position at which the covering portion uncovers the first container unit in the first direction. When viewed in the first direction, a tilting division line is adjacent to the first container unit and tilts with respect to the horizontal direction, and at least a whole of the tilting division line is covered by the single covering portion in the first direction with the covering portion positioned at the covering position.

A first conveying unit is allowed to be in contact with a print medium loaded on an uppermost portion of the one or more print media loaded on a print medium loading unit to convey the print medium from the uppermost portion. The first moving unit moves at least one of the one or more print media and the first conveying unit in each of directions in which the uppermost portion and the first conveying unit are close to each other and directions in which the uppermost portion and the first conveying unit are far away from each other.
