A transport device for a sheet-format substrate has at least one first substrate feed device and has at least one second substrate feed device. The at least one second substrate feed device comprises at least one forward stop and at least one singulating device. At least one substrate guiding device is arranged between the at least one first substrate feed device and the at least one second substrate feed device. The at least one substrate guiding device has at least one directing element. The at least one directing element is mounted such that it is movable or is moved in two different directions independently of one another.

The image forming apparatus may include a main body and a cassette to enter or exit the main body along a first direction to be mounted in or released from the main body, respectively. The cassette may include a supporter extendable in a second direction perpendicular to the first direction to protrude from an exterior of the main body. The main body may include a lever which is movable in the first direction between a supporting position at which the lever supports the main body and a release position at which to allow the cassette to enter or exit the main body along the first direction.

A sheet tray configured to accommodate a sheet includes a first tray, a second tray directly connectable to the first tray, and a third tray directly connectable to the first tray and to the second tray in a state where the second tray is disengaged from the first tray, the third tray being made of metal. The sheet tray is configured to take a first state where the first tray is directly connected to the second tray and a second state where the third tray connects the first tray to the second tray. The sheet tray is configured to accommodate a sheet having a first size in the first state and a sheet having a second size longer than the sheet having the first size in the second state.

An accommodating device includes: a main body portion; a pulling-out portion on which recording media are loaded, the pulling-out portion being capable of being pulled out from the main body portion; a prevention portion configured to prevent the pulling-out portion from being pulled out by being locked to the main body portion in a state where the pulling-out portion is housed in the main body portion; and a fixing portion configured to fix the pulling-out portion to the main body portion in the state where the pulling-out portion is housed in the main body portion.

The image forming apparatus includes a side panel and a manual feed tray that is rotatable and installed on the side panel. The side panel includes an opening portion through which a sheet placed on the manual feed tray passes when the sheet is fed into the image forming apparatus. The manual feed tray includes an end cursor that is movable, and a guide portion that guides movement of the end cursor in a direction perpendicular to a rotational center of the manual feed tray. The opening portion is sized to accommodate the end cursor. When the opening/closing angle of the manual feed tray with respect to a horizontal direction exceeds a predetermined angle, the end cursor moves along the guide portion by gravity to a position where the end cursor can be accommodated in the opening portion.

A sheet stacking device includes a tray having a sheet loading surface on which a sheet fed in a predetermined feeding direction is loaded. The tray includes a main tray, an extension tray and a first detection part. The first detection part includes a first sensor, a first detected piece and a first contact piece. The first detected piece is turnably supported by the extension tray and switches the first sensor between an ON state and an OFF state. The first contact piece is turnably supported by the first detected piece, and protrudes above and retracts below the sheet loading surface.

A transport device for a sheet-format substrate has at least one first substrate feed device and has at least one second substrate feed device. The at least one second substrate feed device comprises at least one forward stop and at least one singulating device. At least one substrate guiding device is arranged between the at least one first substrate feed device and the at least one second substrate feed device. The at least one substrate guiding device has at least one directing element. The at least one directing element is mounted such that it is movable or is moved in two different directions independently of one another.

A feeder includes a body, a mount portion disposed in the body to support from below part of recording media stacked thereon, a lift that raises the mount portion, a support portion connected to the body to support from below another part of the recording media while the mount portion is raised, the support portion being located higher than a position of a mount surface of the mount portion while the recording media are stacked on the mount portion, a blowing portion that blows air between the recording media stacked on the mount portion, and a transport portion that transports the recording media stacked on the mount portion.

A sheet-shaped-medium feeder includes a housing, a mount portion that is disposed to be vertically movable in the housing and that receives sheet-shaped media, a lift that includes line members to vertically raise or lower the mount portion by hanging the mount portion with the line members, and a discharger that transports the sheet-shaped media stacked on the mount portion. The mount portion is changeable to a long mount portion capable of receiving long sheet-shaped media by extending, further upstream in a transportation direction of the sheet-shaped media, an upstream end portion of the mount portion in the transportation direction of the sheet-shaped media. The lift has the line members attached at a portion of the long mount portion corresponding to an unchanged portion of the mount portion, and at a portion of the long mount portion corresponding to an extended portion of the mount portion.

A sheet-shaped-medium feeder includes a housing, a mount portion that is disposed to be vertically movable in the housing and that receives sheet-shaped media, a lift that vertically raises or lowers the mount portion, a discharger that transports the sheet-shaped media stacked on the mount portion in order from an upper one of the sheet-shaped media, and first air outlets that blow air to the sheet-shaped media stacked on the mount portion at left and right edges in a feed width of the sheet-shaped media. The mount portion is changeable to a long mount portion capable of receiving long sheet-shaped media by extending an end portion of the mount portion upstream from an unchanged position in a transportation direction of the sheet-shaped media, the end portion corresponding to an upstream end portion in the transportation direction. The sheet-shaped-medium feeder has a second air outlet that blows air to at least one of left and right edges of the long sheet-shaped media stacked on the extended portion of the long mount portion.
