摘要： An image forming apparatuses includes an apparatus body configured to house a replacement part. The apparatus body includes a guiding face configured to guide a guided face of the replacement part. The guided face is on a side along a movement direction in which the replacement part moves between a set position in the apparatus body and an attaching and detaching position at which the replacement part is attached to and detached from the apparatus body. The apparatus further include a moving device configured to move the replacement part between the set position and the attaching and detaching position, and a pressing device configured to press the guided face of the replacement part against the guiding face of the apparatus body while the replacement part moves between the set position and the attaching and detaching position.

摘要： An article includes a body member and a detachable member detachably attached to the body member. One of the body member and the detachable member includes a cover portion having an engaging portion on an inner wall face of the cover portion. The other includes a covered portion that is covered with the cover portion and has an engaged portion on an outer wall face of the covered portion. The engaging portion and the engaged portion are configured to be disengaged by warping the cover portion so that the cover portion displaces to an outer wall face side of the cover portion. The one of the body member and the detachable member includes a finger-applying-position indicator at a position deviated from a portion corresponding to the cover portion, on an outer wall face of the one. The finger-applying-position indicator indicates a position to be applied with fingers of a user.

摘要： A sheet conveying device includes a sheet container, a separation feeder, a plurality of conveyance drivers, a multifeed detector, a sheet detector, and a conveyance controller. The conveyance drivers are driven to convey a sheet to a conveyance completion position on a sheet conveyance path. The multifeed detector detects occurrence of a multifeed on the conveyance path. The sheet detector detects presence or absence of the sheet at a sheet detection point on the conveyance path. The conveyance controller controls the conveyance drivers to be continuously driven until a preceding sheet preceding multifed sheets is conveyed to the conveyance completion position after the multifeed detector detects the occurrence of the multifeed. The conveyance controller controls the conveyance drivers to stop in a period in which at least one of the multifed sheets is present at the sheet detection point after the preceding sheet is conveyed to the conveyance completion position.

摘要： A document feeder, which may be incorporated in an image forming apparatus, includes a sheet conveying guide, at least one recess, a frame, and at least one protrusion. The sheet conveying guide is disposed facing an exposure glass on an apparatus body and guides an original document passing over the exposure glass when the document feeder is closed to the apparatus body. The recess is disposed on the apparatus body at both ends of the exposure glass in a lateral direction orthogonal to a document conveying direction. The frame is openably closable about one end side of the apparatus body in the lateral direction and vertically movably holds the sheet conveying guide. The protrusion is disposed on the frame facing the recess. The sheet conveying guide and the frame are secured to each other while the recess and the protrusion are engaged with each other in the closed state.

摘要： A sheet conveying device includes a separator to separate a sheet from sheets. The separator includes a separation conveyor; a separation resistance member to press against the separation conveyor via the sheet; a resistance-member holder; a biasing member to contact and bias the resistance-member holder to press the separation resistance member toward the separation conveyor, the resistance-member holder to rotate about a resistance-member rotary shaft to separate from the biasing member in detaching from an apparatus body; and a biasing-member holder configured to rotate about a biasing-member rotary shaft to more incline the biasing member in a state, in which the biasing member is spaced apart from the resistance-member holder, in a moving direction of the resistance-member holder to detach from the apparatus body than the biasing member in a biasing state in which the biasing member biases the resistance-member holder in contact with the resistance-member holder.

摘要： An image reading device includes a plurality of conveyance rollers to convey a sheet, a motor to drive the plurality of conveyance rollers, an image reading unit to read an image of the sheet, a control device to perform a stop control that stops the sheet in a course of a conveyance path, and a clutch to transmit a driving force of the motor. A first conveyance roller group includes at least one of the plurality of conveyance rollers upstream from a leading end of the sheet stopped by the stop control in a conveyance direction, to which the driving force is transmitted via the clutch. A second conveyance roller group includes at least one of the plurality of conveyance rollers downstream from the leading end of the sheet stopped by the stop control in the conveyance direction, to which the driving force is transmitted without the clutch.
