An according to an aspect, a paper feed device includes a device body and a paper feed cassette inserted into the device body along an insertion direction. The paper feed device includes a lock lever mounted to the paper feed cassette via a lever shaft; a spring that applies a rotational force which rotates the lock lever in an engagement direction; and a lock member provided at the device body.

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.

An image forming apparatus includes a sheet feed cassette. The sheet feed cassette has a cylinder lock having a cylinder, and a turning unit coupled to the cylinder to be rotatable integrally with the cylinder. A switch switching part of the turning unit is configured to switch a power switch such that the power switch is in an ON state when an inner cylinder of the cylinder lock is at an unlocked position, and the power switch is in an OFF state when the inner cylinder is at a locked position. A cassette locking part of the turning unit is configured to place a sheet feed cassette of a standard sheet feeder in an unlocked state when the inner cylinder of the cylinder lock is at the unlocked position and place the sheet feed cassette in a locked state when the inner cylinder is at the locked position.

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.

A rotary wire-receiving rack comprises a winding structure, a shaft, a first handle, a lid, a locking slider, and a second handle. The winding structure includes two bars arranged longitudinally in parallel and two rods arranged horizontally in parallel for winding cables. Both ends of the two rods are linked to the bars respectively. The shaft is arranged parallel to and located between the rods. The shaft is pivoted on the bars. The first handle and the lid are respectively fixed at the two ends of the shaft. The lid has a locking hole, and the locking slider is slidably installed on the rod near the locking hole. The locking slider is formed with a locking pin that cooperates with the locking hole. The second handle is pivoted at the end of the bar which closing to the locking hole and having a recess for clamping a cable.

An image forming apparatus, including: an apparatus main body; an openable and closable member provided on the apparatus main body; an image reading portion configured to read an image of an original, the image reading portion being supported on the apparatus main body and being movable to a first position and to a second position; and a stopper member configured to move in conjunction with a movement of the image reading portion, wherein when the image reading portion is moved to the first position, the stopper member is moved to a restricting position for restricting the openable and closable member from moving from a closed position to an open position, and wherein when the image reading portion is moved to the second position, the stopper member is moved to an allowing position for allowing the openable and closable member to move from the closed position to the open position.

Examples of media stops and media storage trays including the media stops are disclosed. In an example, the media stop includes a base including a first end and a second end opposite the first end, a top side, and a bottom side opposite the top side. In addition, the media stop includes a stop wall extending from the top side. The base is to be slidingly coupled to a track of the support surface in a first orientation and a second orientation. When the base is in the first orientation, the first end of the base is more proximate an outer end of the support surface than the second end of the base. When the base is in the second orientation, the second end of the base is more proximate the outer end of the support surface than the first end of the base.

A sheet feeding device includes a sheet accommodating portion mounted in a main assembly. With respect to a crossing direction perpendicularly crossing a pulling-out direction of the sheet accommodating portion from the main assembly as viewed in a direction of gravitation, the main assembly is provided with a positioning portion. A member-to-be-engaged is provided in one of the main assembly and the sheet accommodating portion. An engaging member is provided in the other of the main assembly and the sheet accommodating portion. The engaging member is elastically deformed when the sheet accommodating portion is pulled out in the pulling-out direction from a mounting position. The engaging member is provided swingably in the other one of the main assembly and the sheet accommodating portion so as to be capable of changing a position thereof with respect to the crossing direction.

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.

A sheet feeder including: a housing including a mount portion that receives recording media; an open-close portion that is disposed on an upper surface of the housing to close the mount portion and rotates about a first hinge to open or close a mount space over the mount portion; and a manual insertion portion at least part of which is disposed on the open-close portion to receive manually inserted recording media, the manual insertion portion being rotatable about the first hinge or a second hinge disposed parallel to the first hinge to rotate upward from a position where the manual insertion portion overlaps the open-close portion.
