A sheet feeding device includes a container including a frame, an auxiliary frame member provided on the frame so as to be slidable relative to the frame, and a front cover that covers a front side of the auxiliary frame member, the container being detachably supported in a body of the sheet feeding device; a cover member that covers a top side of the container when the container is attached to the body; and a locking unit that prevents the container attached to the body from being detached from the body when the container is locked and that enables the container to be detached from the body when the container is not locked.

A media restraint for a removable media tray and slidably operable without the use of a pinching force. The media restraint slidably positionable on a track in a removable media tray and is operable without pinching. A pair of pivoting latching cams are used to engage the media restraint to the track and have serrated portions pivotally mounted to a bottom of the media restraint. The media restraint is operable by a finger of the user applying a downward force to an actuator that spreads two cam plates apart which in turn pivot the pair of latching cams to release the media restraint from the track and allowing it to be moved along the track. Upon removal of the downward force, a biasing member lifts the actuator to bring the two cam plates back to their first positions thereby pivoting the pair of latching cams back to reengage with the track.

An image forming apparatus includes a first sheet-transport-path portion that allows a sheet to be transported toward an image forming unit included in an image forming apparatus body; a second sheet-transport-path portion that allows a sheet fed from sheet trays, holding sheets and vertically stacked in multiple rows one above another, to be transported toward the image forming apparatus body; and an opening-closing member supported so as to be movable around a rotation axis between an open position, in which the opening-closing member collectively opens the first sheet-transport-path portion and the second sheet-transport-path portion to an outside, and a closed position, in which the opening-closing member collectively closes the first sheet-transport-path portion and the second sheet-transport-path portion.

An image forming apparatus includes a storing-device body that is drawable from an image-forming-apparatus body, a supporting member attached to the storing-device body and that supports a stack of recording media from below, a feeding member that feeds a top one of the recording media on the supporting member into the image-forming-apparatus body, a moving mechanism that moves the supporting member such that the top one of the recording media on the supporting member comes into contact with the feeding member, a connecting mechanism that connects the moving mechanism to a drive source in conjunction with attaching of the storing-device body to the image-forming-apparatus body, an image forming section that forms an image on the recording medium fed by the feeding member, and a disabling mechanism that disables connection between the drive source and the moving mechanism in conjunction with pushing of the storing-device body into the image-forming-apparatus body.

A latch operating portion, which is made of an elastically deformable constituent material, connected to a knob portion of a latch, and operated by an operator to insert and remove a claw portion provided at a latch beam portion into and from a through hole of trays, is provided, and in a case in which the knob portion is pushed toward a wall portion by a fingertip operation to elastically deform the constituent material, the latch operating portion separates the claw portion from the through hole, restores the elastically deformed constituent material to its original shape when the fingertip is released, and inserts the claw portion into the through hole.

In a lock member of a pull-out lock device, while two adjacent sheet containers are both located at an accommodated position in an image-forming apparatus main body, a contact member is in contact with one of the sheet containers and thus the lock member rotates around a rotation axis, and a lock moves to an unlock position to allow the other sheet container to move in a pull-out direction, and while the other sheet container is located at the accommodated position and the one of the sheet containers is pulled out from the accommodated position in the pull-out direction and thus the contact between the one of the sheet containers and the contact member is removed, the lock member rotates around the rotation axis and the lock moves to a lock position to prohibit the other sheet container from moving in the pull-out direction.

An image forming apparatus includes a sheet feeding cassette which is housed in an apparatus main body in a retractable manner, and a locking mechanism which restricts and releases a pulling out of the sheet feeding cassette from the apparatus main body. The sheet feeding cassette includes an outer cover, and a handle. The outer cover has a recess on an outer surface. The handle is housed in the recess so as to be turned outside from the outer surface, and turned outside by being gripped when the sheet feeding cassette is pulled out from the apparatus main body. The locking mechanism restricts and releases the pulling out of the sheet feeding cassette from the apparatus main body in conjunction with the turning of the handle.

A sheet feeding apparatus includes a casing configured to be connected under an upper casing to which an upper storage portion is drawably attached, a storage portion drawably attached to the casing, and a lock mechanism configured to switch between a locked state, in which the lock mechanism locks the casing and the upper casing to prevent the casing and the upper casing from being separated from each other, and an unlocked state. In in a case where the lock mechanism is in the locked state, a whole of the lock mechanism is positioned outside a movement trajectory of the upper storage portion. In a case where the lock mechanism is in the unlocked state, at least a portion of the lock mechanism is positioned inside the movement trajectory of the upper storage portion.
