Abstract: An image forming apparatus includes an apparatus main body, an operation unit, and a moving mechanism. The operation unit is mounted to the apparatus main body. The operation unit indicates a state of the apparatus main body and performs an input operation to the apparatus main body. The moving mechanism reciprocatably supports the operation unit between a reference position and a retracted position. The reference position overlaps a work area of the apparatus main body. The retracted position does not overlap the work area.

Abstract: An image forming apparatus has an apparatus main body, a cover member, and a coupling member. The cover member is openable and closable relative to a side face of the apparatus main body. The coupling member couples the apparatus main body and the cover member together and is arranged inside the cover member when the cover member is closed. The coupling member is rotatable about a first rotation pivot relative to the apparatus main body. The cover member is rotatable about a second rotation pivot relative to the coupling member. When the cover member is opened relative to the apparatus main body, the rotation center of the cover member switches between the first and second rotation pivots during the opening operation of the cover member.

Abstract: An image forming apparatus includes a cover and a hinge portion. The hinge portion couples the cover with an apparatus main body in openable/closable manner. The hinge portion includes an inner rail member, an intermediate rail member, and a movable rail member. The inner rail member is provided on an inner side of an opening in the apparatus main body, and is arc-shaped. The intermediate rail member is slidably supported by the inner rail member and displaced between a first position and a second position. The movable rail member includes a coupling portion and a supported portion, is slidably supported by the intermediate rail member, and when the cover is opened, is slid from a third position to a fourth position which is further outward of the opening than the third position and at which the coupling portion is disposed below a lower edge of the opening.

Abstract: An image forming apparatus includes a shield case in which a circuit board mounted with an electric circuit is contained. The shield case has an electrical conductive case main body and an electrical conductive lid member. The case main body has an aperture formed in a part of one face. The lid member has one end turnably supported by the case main body and the other end fastened to the case main body by a screw when the aperture is closed. The case main body and lid member have an engaged part and an engaging part engaged with each other when the aperture is closed. The engaging part is formed so as to clamp the engaged part. The shield case is configured so that contact force between the engaging part and engaged part is increased, if the screw is rotated in a fastening direction when the aperture is closed.

Abstract: An image forming apparatus includes a housing, a first discharge opening and a second discharge opening, a sheet discharge portion, a restricting member and a sheet discharge tray. The sheet discharge portion is connected at a position below the first discharge opening, and the sheet discharged through the first discharge opening is to be placed thereon. The restricting member stands up on a downstream side of the sheet discharge portion in a discharging direction of the sheet and can come into contact with a downstream end edge of the sheet discharged to the sheet discharge portion in the discharging direction. The sheet discharge tray includes a first fixing portion and a second fixing portion to be fixed to an upper end part of the restricting member and is attachable above the sheet discharge portion, and a sheet discharged through the second discharge opening is to be placed thereon.

Abstract: A curl correcting device includes a first roller, a second roller and a supporting unit. The supporting unit includes a first conveyance path and a second conveyance path. The first roller is rotated about a first rotary shaft and elastically deformable. The second roller is rotated about a second rotary shaft and elastically deforms the first roller by being pressed against the first roller, thereby forming a curved nip portion between the first and second rollers. The supporting unit is rotatable about a third rotary shaft and rotatably supports the first and second rollers. The first conveyance path communicates with the sheet conveyance path by the supporting unit being arranged at a first position about the third rotary shaft. The second conveyance path communicates with the sheet conveyance path by the supporting unit being arranged at a second position about the third rotary shaft.

Abstract: An image forming apparatus includes an image forming unit, a sheet conveyor and a main body that houses the image forming unit and the sheet conveyor. An operating unit is mounted to a front cover that can move between a closed position to cover an anterior side of the main body and an open position to expose a part of the main body. A retention mechanism retains the front cover at the closed position. The retention mechanism has a lock and a release. The lock is supported by one of the apparatus main body and the front cover and is selectively engageable with and detachable from the other. The release releases engagement of the lock, and is installed posterior to the operating unit in a region facing a back surface as viewed from an opening and closing direction of the front cover.
