A sheet conveying apparatus includes a storage portion to store a sheet, first and second stack portions, first and second conveyance paths to convey a sheet towards the first stack portion and the second stack portion, respectively, a first conveyance unit, a reverse path, and a second conveyance unit. The first conveyance unit is provided downstream of the first conveyance path and reverses and conveys a sheet conveyed to the first conveyance path. The reverse path conveys, once more to the first conveyance path, a sheet that has been reversed by the first conveyance unit. The second conveyance unit is provided in the second conveyance path and downstream of an intersection point between the second conveyance path and the reverse path. While conveying and reversing a sheet conveyed to the second conveyance path towards the reverse path, the second conveyance conveys the conveyed sheet towards the second stack portion.

A recording apparatus includes: a recording unit that performs recording on a medium; a medium discharging section that discharges the medium on which recording has been performed; a medium receiving section that receives the medium discharged by the medium discharging section; a face-down discharge path that guides, to the medium discharge section, the recorded medium with a recorded side thereof facing downward; a document movement path that is provided at an upper part of a housing constituting an outer casing of the recording apparatus and along which a document moves; and a reading unit provided in the document movement path to read the document. The medium receiving section also serves as a support tray that supports the document to be inserted into the document movement path or the document exiting from the document movement path.

A locking mechanism includes a hook, an engaged portion, and a biasing member, and locks a movable unit supported on a unit main body to the unit main body. The hook has a supporting portion pivotably supported on the unit main body and an engaging portion protruding from the supporting portion. The engaged portion is formed on the movable unit and is engageable with the engaging portion. A biasing member biases the hook in such a direction as to let the engaging and engaged portions engage. The hook has a first face facing the engaged portion at the tip end of the engaging portion and a second face extending from the first face toward the supporting portion and inclined relative to the first face in such a direction as to recede from the pivot. With the engaging and engaged portion in engagement, the engaged portion touches only the second face.

A recording apparatus includes a lower unit having a recording section configured to perform recording on a medium, and an upper unit disposed on the lower unit, the upper unit including a reading section configured to read an image of the document, in which the lower unit includes a medium discharge section configured to discharge the medium toward the rear of the apparatus, and a medium receiving section disposed on the apparatus rear side with respect to the medium discharge section, the medium receiving section being configured to receive the medium discharged, and the upper unit is shorter than the lower unit in the apparatus front-rear direction and the upper unit is closer to the apparatus front with respect to the lower unit such that an end portion of the medium receiving section in the medium discharging direction is exposed at the rear of the upper unit.

An image forming apparatus includes an apparatus body, a wall face of the apparatus body having an ejection opening from which a sheet conveyed in a first direction is ejected, a sheet support to support the sheet discharged from the discharge opening in the first direction, and a mount to mount the sheet support to the apparatus body. The mount includes an abutting portion including an abutting face that contacts a wall face of the apparatus body, and a projection projecting in a second direction opposite to the first direction from the abutting face. The abutting face extends in a vertically downward direction from the projection, and the projection is fixed to the apparatus body in a vertical direction.

A sheet conveying device includes a control unit. The control unit determines whether a first sheet and a second sheet being double-fed are in a full double feed state in which the first sheet and the second sheet are conveyed while overlapping each other from distal end parts of the first sheet and the second sheet in a conveyance direction or a partial double feed state in which the second sheet is conveyed while overlapping a rear part of the first sheet than the distal end part of the first sheet, stops an operation of a sheet conveying mechanism when it is determined that the sheets are in the full double feed state, and performs double feed elimination control for eliminating the double feeding of the sheets without stopping the sheet conveying mechanism when it is determined that the sheets are in the partial double feed state.

An image forming apparatus including: an image forming unit; a reverse conveying roller; a discharge unit including: a reverse conveying path; an openable and closable member; an open/close sensor; a discharge tray; a sheet conveyance unit; and a failure detector; and a controller, wherein in a case in which the controller determines that the sheet conveyance unit is in failure based on a detection result of the failure detector and determines that the openable and closable member is closed based on a detection result of the open/close sensor, the controller prohibits discharge of the sheet to the discharge tray and permits conveyance of the sheet to the reverse conveying path, and in a case in which the controller determines that the sheet conveyance unit is in failure and determines that the openable and closable member is open, the controller prohibits the conveyance of the sheet to the reverse conveying path.

A sheet conveyance apparatus includes a first guide provided in an apparatus body, a second guide provided in an openable portion, a flag member supported by the apparatus body pivotally, a detection unit configured to detect pivoting of the flag member, and a jam release guide provided in the apparatus body. In a state where the openable portion is open, the flag member is protruded into a space that is created between the openable portion and the apparatus body by an opening operation of the openable portion. The jam release guide is disposed at a position not hampering conveyance of the sheet in a state where the openable portion is closed, and is disposed to come in contact, together with the flag member, with a jammed sheet to regulate a posture of the jammed sheet in a state where the openable portion is open.

A sheet feed device includes: a stacking tray on which sheets are stacked in such a manner as to be capable of being lifted and lowered; and a position restricting member configured to come into contact with a sheet end portion to restrict a position of the sheets. The position restricting member is provided to an opening/closing member capable of being opened and closed. When the opening/closing member is closed, the position restricting member restricts a position of the sheet end portion in an opening/closing direction of the opening/closing member.

A printing device includes a print section. A main unit, which has a supply port via which the medium is to be inserted on its upper surface. The medium inserted via the supply port is to be guided to the print section along an upper feeding route. This upper feeding route has a first curve at its midway point. Positioned below the main unit is a medium storage section that accommodates a medium. The medium accommodated in the medium storage section is to be guided to the print section along a lower feeding route. This lower feeding route has a second curve at its midway point, where the medium is to be turned around. The main unit includes: a first cover that allows the upper feeding route to be exposed; and a second cover that allows the lower feeding route to be exposed.
