A feeding apparatus includes a feeding member, first and second conveying members, a separation member, and drive and control units. The feeding member feeds a recording material placed on a tray. The separation member and the first conveying member form a nip portion and separates recording materials at the nip portion. The second conveying member conveys a conveyed recording material. The drive unit drives at least the feeding member. The control unit controls to feed first and second recording materials such that a second recording material front edge passes the nip portion before a first recording material rear edge passes the nip portion, and controls to stop the second recording material after the second recording material front edge has passed the nip portion such that the first recording material rear edge reaches the second conveying member before the second recording material front edge reaches the second conveying member.

A drawer unit includes: a drawer member allowed to shift toward a storage unit in an inserting direction, or shift from the storage unit in a drawing direction; a lock member rotatably supported by the drawer member; a first regulation member that engages with the lock member to regulate a shift of the drawer member when the drawer member is located at a first position; a second regulation member that engages with the lock member to regulate a shift of the drawer member when the drawer member is located at a second position; and an operation unit that receives a first operation that rotates the lock member in the drawing direction to allow engagement between the lock member and the first regulation member, and a second operation that rotates the lock member in the inserting direction to allow engagement between the lock member and the second regulation member.

An image forming apparatus includes a casing; a process unit for forming a developer image on a sheet; an image exposing unit; a sheet cassette detachably mounted to the casing; a feeding roller for single the sheet from the cassette; a feeding guide provided in the casing and configured to guide the sheet moving from the cassette to the process unit. The exposing unit is disposed right above the feeding roller. The process unit is at a position the same position as the exposing unit in the vertical direction and downstream of the exposing unit in a horizontal direction. The cassette is below the feeding roller. The guide is between the exposing unit and the cassette in the vertical direction. The guide includes upper and lower guides. When the cassette is drawn out of the casing, the lower guide moves to an accommodating portion in the cassette.

An image forming apparatus includes a sheet cassette, a sheet conveying portion, an image forming portion, a position detecting portion, and an image position correcting portion. The sheet conveying portion conveys a sheet from the sheet cassette attached to the apparatus main body, along a sheet conveyance path whose width direction matches the main direction. The position detecting portion detects a position of a detection-target portion that is a part of the sheet cassette, in the main direction based on the apparatus main body. The image position correcting portion corrects an image formation position in the main direction at which the image is formed by the image forming portion, based on the position detected by the position detecting portion.

A sheet feeding device includes a sheet feeding cartridge, a pair of fixed rails, a pair of movable rails and a pressing part. The sheet feeding cartridge has a pair of side plates extending in taking-out/taking-in directions and is taken out/in an installed part in an apparatus main body. The fixed rails are extended in the taking-out/taking-in directions in the installed part. The movable rails are provided to move in the taking-out/taking-in directions along the fixed rails. If the pressing part is provided in one side plate, the pressing part applies biasing force to one movable rail facing to one side plate so that another side plate comes into pressure contact with another movable rail. If the pressing part is provided in one movable rail, the pressing part applies biasing force to one side plate so that another side plate comes into pressure contact with another movable rail.

An image forming apparatus includes a housing and a pair of cassette guides. The housing is provided with a cassette storage space and a unit storage space. The unit storage space is disposed above the cassette storage space and configured to slidably support an image forming unit. The housing has a pair of side plates arranged to be opposite to each other in a direction intersecting a sliding direction of the image forming unit. The pair of cassette guides is provided in the cassette storage space and arranged inside the pair of side plate. A guide rail part is formed by a gap between the side plate and the guide cassette arranged inside the side plate, and a top face of the cassette guide. A unit-side rail provided to the image forming unit is slidably engaged with the guide rail part.

A paper feed tray includes a cassette, a regulation plate which is slidably attached to the cassette, a cover provided to the regulation plate, a locking portion which is covered with the cover and engages with the cassette to fix a position of the regulation plate, and a lever. The lever includes a coupling portion coupled with the locking portion, a depression portion configured to be depressed toward one side in a direction of sliding of the regulation plate, and an intermediate portion provided between the coupling portion and the depression portion. The lever operates the locking portion to be disengaged from the cassette upon the depression portion being depressed toward the one side. The cover includes an extension extending while facing the intermediate portion. A space, which is open at a tip to which the extension extends, is formed between the extension and the intermediate portion.

A paper feeding device of an embodiment includes a paper feed cassette, an alignment component, a fan, and a fan guiding duct component. A paper bundle in which a plurality of sheets of paper are stacked can be placed on the paper feed cassette. The alignment component can align the paper bundle placed on the paper feed cassette. The fan is connected to the alignment component. The fan can generate airflow. The fan guiding duct component is connected to the alignment component. The fan guiding duct component is positioned above the paper bundle placed on the paper feed cassette. The fan guiding duct component generates a negative pressure between the fan guiding duct component and an uppermost sheet of paper in the paper bundle due to the airflow from the fan.

Provided is a printing apparatus including a cassette configured to be capable of managing a stored paper-sheet by using paper-sheet size information and paper-sheet attribute data, in which an adjustment value of a print position is registered to copied paper-sheet attribute data if an event in which the adjustment value is registered to paper-sheet attribute data in which the paper-sheet size information is not set occurs.

A coupling mechanism of the present disclosure includes a drive transmission member, a coupling member and a biasing member. The drive transmission member includes a shaft portion and an engagement pin. The coupling member includes a plurality of engagement protrusions and a holding protrusion which is smaller than the engagement protrusion. The holding protrusion makes contact with the engagement pin in a state where the engagement pin makes contact with the pressing surface. A load in a reverse rotation direction is applied from the holding protrusion to the engagement pin when the coupling member is reversely rotated.
