A sheet material feeding device includes: a housing; a cassette configured to internally house a sheet material, and capable of being pulled out of the housing and housed into the housing; a rear-end regulating member provided inside the cassette and configured to regulate a position of an upstream end of the sheet material in a sheet material feeding direction; a rear-end displacing member supported by the rear-end regulating member and configured to swing along the sheet material feeding direction; a sliding member provided for the cassette, having an engagement part to be engaged with the rear-end displacing member, and configured to slide toward a downstream side in the sheet material feeding direction to displace the rear-end displacing member toward the downstream side in the sheet material feeding direction; and a first energizing member configured to energize the sliding member toward an upstream side in the sheet material feeding direction.

A sheet feeding cartridge attached to or detached from a cartridge storing part formed between a pair of side face covers which constitute a part of an exterior cover of an apparatus main body. The sheet feeding cartridge includes a cartridge base on which a sheet is stacked, a cartridge cover attached so as to be slidable in a width direction perpendicular to the attachment direction, a first positioning part configured to position the cartridge base to the cartridge storing part and a second positioning part configured to position the cartridge cover with respect to the side face covers in the width direction perpendicular to the attachment direction.

An image forming device includes a device body; a conveyance table that is inserted into and pulled out of the device body and that forms a conveyance path for a sheet; a sheet mount tray; a paper feeder that feeds the sheet from the sheet mount tray to the conveyance path; and a movable support that movably supports the paper feeder on the conveyance table in a state where the conveyance table is pulled out of the device body. The paper feeder covers a predetermined part of the conveyance path in a state where the paper feeder disposed on the conveyance table is inserted into the device body, the sheet mount tray is disposed in the device body and separates from the paper feeder when the conveyance table is pulled out of the device body, and the paper feeder moves away from the predetermined part.

A sheet feed cassette monitor includes an actuator with another end portion, a detecting circuit, a plurality of protrusions, a signal monitoring circuit, and a signal determining circuit. When the one end portion is in contact with a paper sheet, the other end portion swings in a first direction. When the one end portion is not in contact with the paper sheet, the other end portion swings in a second direction opposite direction to the first direction. The detecting circuit detects the swinging of the other end portion on the actuator. The plurality of protrusions are convexly installed in an asymmetric manner with respect to a putting-in/taking-out direction of the feed cassette. The signal determining circuit determines a presence/absence state of the paper sheet housed in the sheet feed cassette and an open/close state of the sheet feed cassette based on a pattern of change in the monitored signal.

An image-forming apparatus includes: a casing; a first sheet tray provided in a bottom portion of the casing; an image-forming unit configured to form an image on a sheet supplied from a sheet accommodation portion of the first sheet tray; a sheet supplying path; a first conveying path; and a shutter. The sheet supplying path is configured to provide communication between the sheet accommodation portion and the image-forming unit. The first conveying path is provided in one of the casing and the first sheet tray, and has one end formed with an opening and another end configured to communicate with the sheet supplying path, the opening being open downward. The shutter is movable between a closing position closing the first conveying path and an opening position opening the first conveying path.

A removable media tray assembly for an image forming device according to one embodiment includes a media tray having a bottom surface and a front wall extending upward from the bottom surface. A bottom surface defines a media storage location for storing a stack of media sheets. The assembly includes a housing having an opening therein to receive the media tray. A magnet and a plate provide a latching force FL greater than a pick motor stall force keeping the media tray in a closed position during media picking. A handle assembly including a finger bar and a pivoting link is mounted to the front wall. With the media tray being held closed by the latching force, a user-supplied actuation force FA that is less than 22.2 N applied to the finger bar, pivots the link which acts as a force multiplier providing a release force exceeding the latching force.

A sheet storage apparatus includes a storage unit configured to store sheets, a biasing unit configured to apply a biasing force to the storage unit so that the storage unit is biased toward a mounting position, and a regulating unit configured to be located at a first position at which movement of the storage unit in a drawing out direction is regulated and a second position at which movement of the storage unit from the mounting position in the drawing out direction is permitted. The regulating unit is moved from the first position to the second position in response to an operation by an operator who operates a handle.

An image recording device having a recording unit to record an image on a sheet is provided. The image recording unit includes a feed guide defining a first conveying path; an arm disposed between the recording unit and the tray, the arm having a feed roller rotatably disposed at a free end and configured to feed the sheet in the tray to the first conveying path. The arm pivots between a first arm position, and a second arm position. The return guide pivots between a first return guide position, and a second return guide position. A space occupied by the return guide in the first return guide position overlaps a space occupied by the arm in the second arm position. The return guide is in the second return guide position when the arm is in the second arm position which is retracted from an insertion space occupied by the tray.

A paper sheet handling device that facilitates removal of paper sheets blocked on a conveying path. The device includes a safe casing internally provided with a paper sheet storage box; a processing unit capable of being pulled out from, or stowed in, a main device; a conveying section coupled to the processing unit, and that forms a conveying path; a handover section coupled to a top plate of the safe casing to hand over the sheets between the storage box and the conveying path; and a positioning section that positions for connecting the handover section and the conveying path together when the processing unit is being stowed in the main device.

An image forming apparatus and roller separation device are provided. The image forming apparatus including a main body having a print unit, a first paper feeding unit containing print paper and insertable in or pullable from the main body, a feed roller in the main body feeding the print paper from the first paper feeding unit to the print unit and comprising a driven roller contacting a driving roller, an elastic member applying an elastic force to the driven roller in a direction to contact the driving roller, a handle member in the main body movable to a first position and a second position, and a separation member connected to the handle member and switched to a normal position separated from the driven roller and a separation position separating the driven roller from the driving roller.
