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.

A medium conveying apparatus includes: a housing having an engaged portion and a guide surface; a placement tray having an engaging portion and a placement surface; and a side guide mounted on the placement surface and protruding downstream beyond the placement tray to restrict a medium in a width direction. The engaged portion restricts entry or removal of the engaging portion when the placement surface forms a first angle with the guide surface, and allows entry or removal of the engaging portion when the placement surface forms a second angle different from the first angle with the guide surface in attachment of the placement tray to the housing or detachment of the placement tray from the housing. A downstream end of the side guide in the conveying direction does not intersect with the guide surface as viewed from the width direction when the placement surface forms the second angle.

A medium transport portion includes a main body portion, a tray unit, and a support guide member. The main body portion includes a first manual feed path and a second manual feed path. The tray unit can be accommodated in the main body portion in a non-use state, and a medium is mounted thereon in a use state. The support guide member is movable in a Z-direction, and supports the tray unit such that a first position that the tray unit is positioned in the first manual feed path, a second position of being positioned in the second manual feed path, and a third position of being accommodated in the main body portion are switched.

A sheet conveying device is provided with an auxiliary tray provided so as to be able to come in and out of a main tray for feeding a sheet or discharging a sheet provided on a side surface of an image forming apparatus main body so that a sheet can be placed thereon, a blade provided so as to be able to come in and out of the auxiliary tray, and a spring portion configured to urge the blade in a direction in which the blade is expanded from the auxiliary tray. When the auxiliary tray is expanded, the blade is expanded in a width direction of the auxiliary tray by the spring portion.

Provided is a technique that enables proper sorting of discharged print media by suppressing curling of each of the print media sufficiently. A determining unit determines a curling suppressing operation to be executed such that in a case where sorting operation is executed, the suppressing operation having a higher effect of suppressing curling is executed than in a case where the sorting operation is executed. Then, a print control unit controls a print head to perform printing on print media while executing the suppressing operation determined by the determining unit.

Disclosed is a drawing apparatus including: a base member; and a drawing member that is attached so as to be capable of being drawn and pressed in a reciprocating direction with respect to the base member, wherein the base member has a couple application mechanism that applies a couple for correcting skewing of the drawing member with respect to the reciprocating direction to the drawing member as a reaction of a force by which the drawing member is pressed, and wherein the couple application mechanism is configured so that a distance between action lines of two forces generating the couple becomes large as a pressing amount of the drawing member with respect to the base member increases.

A paper feed device includes a paper-feed cassette configured to be removably inserted to a cassette accommodation unit, a rail member provided at an inner wall of the cassette accommodation unit, an engaging portion to engage with the rail member so as to be able to move, a rotating member configured to be brought into contact with an engagement surface of the engaging portion and be able to rotate in association with insertion and removal of the paper-feed cassette, a shaft member configured to pivotally support the rotating member and have one end fixed to the rail member or an inner wall of the cassette accommodation unit, and a supporting member configured to support another end of the shaft member. The supporting member is shaped so as to be able to change an attachment posture relative to the rail member or the inner wall.
