Disclosed is a web handling system that includes a spindle having a spindle magnetic coupling portion and a roll core configured for receiving the spindle for mounting thereon and having a roll magnetic coupling portion, wherein the spindle and roll magnetic coupling portions are configured for magnetically attracting each other to hold the roll on the spindle.

A drive transmitting device, which is included in an image forming apparatus, includes a drive source, a drive transmitting body, and a rotary shaft. The drive transmitting body has a press-in target portion. The rotary shaft includes a press-in portion mounted on one end of the rotary shaft in an axial direction of the rotary shaft to be pressed into the press-in target portion of the drive transmitting body. The press-in portion includes a flat face and a plurality of circular arc faces having different distances from an axial center of the rotary shaft and being disposed at a same position as at least a portion of the flat face in the axial direction of the rotary shaft. A radius of curvature of one of the plurality of circular arc faces is greater than a radius of curvature of another of the plurality of circular arc faces.

To enable placement of a regulating member which regulates a position of an end of a paper sheet at a desired position, and stable sheet feeding. A fixing member for standard size (33) is guided to engage with a fixing hole for standard size (42) and, in a state where the fixing member for standard size (33) positions a trailing end regulator (24), a fixing member for non-standard size (34) does not engage with a rack gear (43).

A sheet storage cassette of the present disclosure includes a sheet storage portion, a rack and a cursor. The cursor aligns sheets. The cursor includes a regulation portion which makes contact with the side ends of the sheets and a lock portion which includes at least one engagement protrusion that engages with the rack teeth of the rack. The at least one engagement protrusion each includes a second inclination surface which is inclined from a tip end portion toward a base portion in a second direction opposite to a first direction. At least one of the engagement protrusions includes a second vertical surface which is extended vertically downward from the base portion toward the tip end portion. At least one of the engagement protrusions includes a third inclination surface which is inclined in the second direction and which is extended to the tip end portion of the engagement protrusion.

An improved elastomer covered feed roll assembly (32R) for use in a feed/pull roll set combination (36) in a sheet finishing machine (12) comprises a roll core (50) having a cylindrical surface (60) with multiple longitudinally spaced and circumferentially offset elongated keyways (80, 82, 84, 86) each configured as a locking slot. Multiple replaceable flexible feed cover sections (52, 54, 56) each incorporating a flexible backing (120) and an elastomeric layer or coating (122) are removably mounted on the roll core by locking components (74, 76) on opposite ends (70, 72) of each of said replaceable flexible feed cover sections, the locking components of each replaceable flexible feed cover section engaging a locking slot (80, 82, 84, 86) corresponding to the feed cover section. The keyways draw together the opposite ends (70, 72) of corresponding cover sections to form corresponding end joints (96, 98, 100).

A sheet storing cassette includes a cassette base, a sheet stacking plate, a cursor rail, a regulation cursor, and an adjustment member. The regulation cursor has a first regulating portion which forms a first sheet regulating face for positioning the sheets placed on the sheet stacking plate in the sheet feeding direction. The cursor rail has a plurality of engaged portions with which an engaging portion provided on the regulation cursor meshes when the regulation cursor is moved such that the first sheet regulating face is arranged at standard-size positions corresponding to a standard-size sheet. The adjustment member has a second regulating portion that offsets, when the adjustment member is attached to the regulation cursor arranged at one of standard-size positions, the first sheet regulating face to a second sheet regulating face corresponding to a non-standard size sheet.

A sheet end position regulating device, which is included in an image forming apparatus, includes a first contact body disposed movable on a sheet loading portion on which a sheet is loaded and configured to contact an end portion of the sheet, a fixing body disposed movable between a fixing position at which a position of the first contact body to the sheet loading portion is fixed and a releasing position at which the position of the first contact body is released, and a second contact body disposed movable between a contact position at which the fixing body contacts a contact target portion to regulate movement of the fixing body form the fixing position to the releasing position and a non-contact position at which the fixing body does not contact the contact target portion.

A feeding device includes a first feeding unit, a second feeding unit, and a fixing structure. The first feeding unit feeds a first recording medium. The second feeding unit is located below the first feeding unit and feeds a second recording medium. The fixing structure takes a first posture or a second posture differing from the first posture. The fixing structure fixes the second feeding unit to the first feeding unit when the fixing structure is in the first posture. The fixing structure fixes the second feeding unit to the first feeding unit by fixing a third frame member of the second feeding unit to a second frame member of the first feeding unit. When the fixing structure is in the second posture, the fixing structure releases linkage between the second feeding unit and the first feeding unit.

A postal sorting machine comprises an unstacker in a mailpiece feed inlet, a sorting conveyor, and sorting outlets, each of which is provided with a receptacle designed for storing the mailpieces in a stack and on an edge. Each sorting outlet is provided with a wheel having a helical blade. The wheel projects through an opening in the bottom of the receptacle and is mounted on a transmission shaft. The transmission shaft is disposed under the receptacle to impart a rotary movement to the helical blade so that the helical blade pushes the base of a current mailpiece in the receptacle against the stack of mailpieces that is being formed. The wheel is also mounted on the transmission shaft by being clipped by moving in translation across the axis of rotation of the transmission shaft.

A sheet feeding device includes: a feeding unit that is provided to be movable in a forward-backward direction to move forward or backward relative to a sheet placing unit on which a sheet is placed, and feeds the sheet; a moving unit that moves the feeding unit in the forward-backward direction; a contact unit that is provided to be movable, with which the sheet placed on the sheet placing unit is brought into contact; a limitation unit that limits movement of the contact unit; and a releasing unit that, when the moving unit moves the feeding unit in a direction away from the sheet placing unit, with the movement of the feeding unit, releases limitation on the movement of the contact unit by the limitation unit.
