A sheet feeding device includes a feeding roller pair, a first guide, a door including a second guide and rotatable between a first direction and a second direction opposite to the first direction through first to third positions, a damping mechanism, and an engaging portion including an elastic member. A first resisting force is set so that moment acting around a shaft by a self-weight of the door is larger than the first resisting force of the damping mechanism when the door is positioned between the second position and the third position. A resultant force of the first resisting force of the damping mechanism and a second resisting force of the elastic portion is set so that the moment acting around the shaft by the self-weight of the door is larger than the resultant force when the door is positioned between the second position and the third position.

According to one embodiment, an image processing apparatus includes an apparatus main body, a first rotating body, a second rotating body, and a connection member. The first rotating body is configured to be openable and closeable and provided in the apparatus main body. The second rotating body is provided in the first rotating body. The second rotating body is configured to be openable and closable from the first rotating body in the same direction as that of the first rotating body. The connection member is linear. The connection member is configured to connect the apparatus main body and the second rotating body to each other and to restrict a rotation angle of the second rotating body.

There is provided a print device including: a casing having an inner space; a support which extends along a first direction and which is configured to rotatably support a roll body; a conveyer configured to convey a sheet pulled out of the roll body in a conveyance orientation along a second direction orthogonal to the first direction; a print unit configured to perform a print by causing a print matter to adhere to the sheet conveyed in the conveyance orientation; and a cover. An opening is provided on the casing such that the inner space is exposed to an outside of the casing via the opening. The cover is configured to slide relative to the casing along the second direction between an open position in which the opening is uncovered and a close position in which the opening is covered by the cover.

A medium conveying apparatus includes a cover that is supported by a main body so as to be arranged in an opening position or a closing position, an arm that protrudes into a conveying path formed between the cover and the main body and is retracted from the conveying path, a lock mechanism that fixes the cover to the main body with the cover arranged in the closing position, and a mechanism that retracts the arm from the conveying path when the lock mechanism shifts from a first state in which the lock mechanism releases the cover from the main body to a second state in which the lock mechanism fixes the cover to the main body.

An automatic document feeder includes a media path to route media through the automatic document feeder, an opposing roller pair to route media along the media path, and a media tray to receive the media from the media path, the media tray to be opened, and the opposing roller pair to be disengaged when the media tray is opened.

A recording apparatus includes a recording head, a loading unit, a feeding unit, a cover, a detection unit, and a determination unit. The feeding unit feeds a recording medium loaded on the loading unit to a recording position where the recording head performs the recording. The cover moves between an opening state and a closing state. The determination unit determines a size of the loaded recording medium based on a result of a width detection operation. The recording head records an image per a determination result. If the cover closing is detected before the recording is performed, the determination unit performs the width detection operation to determine the recording medium size loaded on the loading unit. If the cover opening is detected and the recording apparatus receives a recording instruction, the determination unit performs the width detection operation to determine the recording medium size loaded on the loading unit.

A transportation portion includes an apparatus body, a cover, first and second path formation portions, and a movement portion. The apparatus body has a transportation path including a downward path and an upward path having portions located at the same level in the Z direction. The cover covers and uncovers the transportation path. The first path formation portion is movable to a first position and to a second position. The second path formation portion defines the upward path and defines the downward path with the first path formation portion. The movement portion moves the first path formation portion in response to opening or closing of the cover. The first path formation portion is positioned in a movement area during a closed state. The movement portion moves the first path formation portion to the second position when the cover is opened and to the first position when the cover is closed.

An image forming apparatus includes a main body housing, an openable/closable part, a sheet feeding tray, an image forming device, a sheet feeding roller, a first coupling, a drive gear, a second coupling, a biasing member, and a link mechanism. The first coupling is provided in the sheet feeding roller. The second coupling is provided coaxially with the drive gear, rotatable following the drive gear, slidable relative to the drive gear in an axial direction and capable of fitting to the first coupling. The biasing member biases the second coupling to the first coupling to connect the second coupling to the first coupling. The link mechanism disconnects the second coupling from the first coupling against a biasing force of the biasing member so as to block a transmission of the drive force with an opening of the openable/closable part.

Provided is an image forming system capable of reliably preventing others from removing and taking printed matter even though printing is executed beforehand. The confidential notation reading unit reads a confidential notation. The user storage tray has a structure from which outputted printed matter cannot be removed unless the opening/closing door is opened. The locking mechanism locks the opening/closing door. The sorting mechanism sorts the printed matter outputted from the image forming apparatus and outputs the printed matter to either the open tray or the user storage tray. The sorting control unit outputs printed matter to which a confidential notation is not added to the open tray, and outputs a printed matter to which a confidential notation is added to the user storage tray, respectively.

A sheet conveyance apparatus (26) includes: a first conveyance unit (70a), a second conveyance unit (70b) disposed below the first conveyance unit (70a) and including a second upper conveyance guide (75) and a second lower conveyance guide (77), and an apparatus main body, wherein the second conveyance unit (70b) can be drawn out to a front side of the apparatus main body along a front-and-rear direction perpendicular to a sheet conveyance direction, the second upper conveyance guide (75) includes: a guide main body part (75b) turnable upward and downward with respect to the apparatus main body with a rear end edge as a turning support shaft and a front end edge as a turning end; and a movable guide part (75c) coupled to the turning end of the guide main body part (75b) via a hinge part (75d) in a turnable manner.
