An image forming apparatus, including a main chassis having a discharge tray and a switchback tray in an upper position with respect to the discharge tray; an image forming unit; a discharge roller to discharge a recording sheet conveyed through the image forming unit onto the discharge tray; a duplex conveyer to invert the sheet and convey the inverted sheet to return to the image forming unit; and a switchback roller being rotatable in a normal direction to convey the sheet toward the switchback tray and a reverse direction to convey the sheet to the duplex conveyer; is provided. The main chassis includes a pair of walls, each of which extends in a vertical direction and in a conveying direction of the sheet and is arranged in adjacent to the switchback tray such that the switchback tray is interposed between the pair of walls.

A position controller for electronically monitoring the position and speed of a dredge. The position controller consists of an electric powered line winding spool with an electric encoder to indicate line speed and position to a microprocessor. A drag control assembly with electric control is used to increase, decrease or set the drag at desired setting by microprocessor control. Touch screen microprocessor interface is the preferred method to enter settings into the system and allow display/control through multiple preexisting marine electronic devices throughout a fishing boat.

A scanner includes a reading unit that reads an image of a paper, a medium feeding portion that is capable of selecting a first feeding mode in which a separation feeding for separately feeding a paper bundle in which a plurality of sheets of paper is overlapped with each other is performed and a second feeding mode in which a non-separation feeding for collectively feeding the paper bundle without separating is performed, and a pair of first transporting rollers and a pair of second transporting rollers that transport the paper fed by the medium feeding portion, in a case in which the medium feeding portion feeds the paper in the second feeding mode, a first driven roller and a second driven roller respectively constituting the pair of first transporting rollers and the pair of second transporting rollers are driven in a rotation direction where the paper is transported.

A drive switching device includes: a covering member that is rotatably provided on a support shaft provided in a housing including a driver, and is rotatable from a closed position for covering an inside of the housing to an open position for exposing the inside of the housing; an input unit that is provided in the covering member, and receives an input of displacement caused by rotation of the covering member; a release member provided in a direction apart from the input unit inside the housing and including a cam that moves in conjunction with movement of the input unit, the release member being configured to, upon rotation of the covering member toward the open position, disconnect a drive transmission path of the driver by the cam; and multiple links connected to the input unit and the cam, the multiple links being configured to, upon rotation of the covering member, move the cam in an opposite direction to a direction in which the input unit is moved.

An image forming apparatus is capable of easily changing a scheduled stacking position of any image forming job. An image region in which an overall arrangement mode of the image forming apparatus and sheet discharge apparatus is displayed and a list region in which standby jobs are listed are displayed on a monitor screen. In the image region, a sheet bundle of the selected standby job is displayed on a tray that is set as the scheduled stacking position of the selected standby job. When the sheet bundle is selected and dragged and dropped by a mouse pointer on the monitor screen, the tray being set as the scheduled stacking position is changed, and a position at which the sheet bundle is displayed is also changed.
