Abstract: A sheet conveying device includes a correcting unit. The correcting unit corrects displacement of a sheet conveyed from an upstream side conveying path, and conveys the sheet to a downstream side conveying path. The correcting unit includes a first conveying part conveying the sheet, a first moving part moving a first frame supporting the first conveying part and a detecting part detecting a side end edge of the sheet at a reference position without displacement. The first conveying part stops conveyance of the sheet when a leading end of the sheet reaches the detecting part. While the driving of the first conveying part is stopped, the first moving part moves the first frame to move the sheet, and stops movement of the first frame, when detection result of the detecting part is changed, to position the side end edge to the reference position to correct displacement of the sheet.

Abstract: A holding member of a sheet feeder includes a locking member engageable with a part of a pinion gear and holds the pinion gear and a sensor member. The holding member is detachably attachable to the sheet storage portion. The pinion gear and a pair of rack members are meshed with the holding member attached to a sheet storage portion. The holding member holds the pinion gear movably in an axial direction of the rotary shaft so that the pinion gear is displaceable between a first position where the rotation of the pinion gear is regulated and a second position where the pinion gear is rotatable. The pinion gear is located at the first position with the holding member detached from the sheet storage portion and located at the second position with the holding member attached to the sheet storage portion.

Abstract: A paper feeder includes a housing, a driving unit, a sheet loading portion, a paper feeding unit, and a lock mechanism. The lock mechanism is located in the housing. The paper feeding unit includes a pickup roller, a second shaft portion, a feed roller, a holder, and a stopper. The stopper is swingably supported in the holder, and is configured to change states between a regulation state and a permission state. The regulation state is a state that regulates entrance of the sheet to be loaded in the sheet loading portion into a side of the feed roller side corresponding to the second position of the holder. The permission state is a state that permits entrance of the sheet into the feed roller side corresponding to the first position of the holder. The lock mechanism locks the holder in the second position at a time of non-paper feeding.

Abstract: A fixing device includes a pressing roller, a rotating member, a heating means, a pressing mechanism, a separation member, a first biasing member and a moving mechanism. The pressing roller has a core metal and an elastic layer. The separation member includes a contact part. The first biasing member is configured to bias the separation member to be rotated in a direction in which the contact part is butted against the rotating member. The first biasing member includes a first end portion by which biasing force is acted on the separation member and a second end portion opposite to the first end portion. The moving mechanism is configured to move the second end portion of the first biasing member in a direction in which the biasing force is decreased, as the core metal approaches the rotating member owing to decrease in rigidity of the elastic layer of the pressing roller.
