摘要： An image forming apparatus includes a recording device and an apparatus body to internally house the recording device. The apparatus body includes an attachment unit to be removably mounted in the apparatus body and an apparatus body-side connector. The attachment unit includes an attachment-side connector to be electrically connected to the apparatus body-side connector. The apparatus body also includes a pressing portion to press the attachment unit in a direction in which the attachment-side connector faces the apparatus body-side connector in a state where the attachment unit is attached to the apparatus body. The direction is orthogonal to a mounting direction of the attachment unit. The apparatus body further includes a movable member holding the pressing portion movable between a first position where the pressing portion is closest to the apparatus body-side connector and a second position where the pressing portion is farthest from the apparatus body-side connector.

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 rotation drive device includes a driven rotation member, a driving rotation member, a rotation relay member, a shaft, and a holder. The rotation relay member transmits only a unidirectional rotational driving force from the driving rotation member to the driven rotation member. The rotation relay member includes a housing and a cylindrical one-way clutch. A contact portion between the driving rotation member and the shaft is configured to rotate the driving rotation member and the shaft to transmit the driving force to an inner peripheral side of the cylindrical one-way clutch via the shaft. The driving rotation member includes a boss projected toward the holder and rotatably held in the holder. A portion of the shaft to support the driving rotation member and an inner wall surface of a through hole of the driving rotation member are shaped to rotate the shaft and the driving rotation member. together.

摘要： An image reading device, which is included in an image forming apparatus, includes a first transparent body, a second transparent body, a holding body, and a reading body. The second transparent body is disposed separated from and inclined at a predetermined angle to the first transparent body. The holding body holds the first and second transparent bodies. The reading body moves in a sub-scanning direction along the first and second transparent bodies. The holding body includes a flat face and a frame-shaped face. The flat face is contiguous to the first transparent body on a same plane and smoothly connected with the second transparent body. The frame-shaped face projects outwardly beyond the second transparent body facing the reading body. The reading body moves and contacts the first transparent body and the holding body, and moves with a gap relative to the second transparent body.

摘要： An automatic document feeder, which is included in an image reading device and an image forming apparatus, includes first and second document trays, a document output tray, a document conveying passage, multiple document conveying bodies, a drive source, a detector, and a controller. The multiple document conveying bodies include a document holding and conveying body to convey and hold the original document sheet on the second document tray. On detection of the original document sheet on the second document tray while conveying a different original document sheet from the first document tray, the controller stops feeding the different original document sheet, causes the different original document sheet downstream from the document holding and conveying body in a document conveying direction to be conveyed to the document output tray, and stops the drive source after the different original document has been conveyed to the document output tray.
