A rotating body unit includes a pair of bearing portions and a first engagement portion. A pair of bearing support members support the bearing portions when at support positions, and release the bearing portions when at retraction positions. An auxiliary tool includes a pair of arm portions and a second engagement portion. When the auxiliary tool is engaged with the rotating body unit mounted in the mounting portion, the arm portions abut on and move the bearing support members from the support positions to the retraction positions. The second engagement portion engages with the first engagement portion after the bearing support members move to the retraction positions. As the auxiliary tool is separated from the mounting portion with the second engagement portion engaging with the first engagement portion, the rotating body unit is pulled out of the mounting space integrally with the auxiliary tool.

A bearing which supports one end side of a driving roller includes a first restriction portion which is restricted from rotating and moving with respect to a first frame, and a bearing which supports the other end side of the driving roller includes a second restriction portion which is restricted from rotating and moving with respect to a second frame. As viewed from a direction perpendicular to a width direction of an intermediate transfer belt, a phase of shape of the first restriction portion in a state of being held by the first frame and a phase of shape of the second restriction portion in a state of being held by the second frame are equal to each other.

A deflection roller (32) for a deflection roller package (33) of a wire saw (1), having a wheel (32), a pivot bearing (42) and a sealing element (55). The wheel (32) has a raceway (45) along the periphery thereof for guiding a saw wire (3) of the wire saw (1). The pivot bearing (42) is coaxially inserted in the wheel (32). An outer sleeve (51) protrudes from a lateral surface (49) of the wheel (32). An inner sleeve (50) protrudes from a lateral surface opposite the one lateral surface (49). A radius (53) of the inner sleeve (50) is smaller than a radius (52) of the outer sleeve (51). The sealing element (55) is placed on the outer sleeve (51) or inserted into the inner sleeve (50).

A roll holder is for a label roll of linerless labels wound in a crosswise manner. The roll holder has: a horizontally arranged spindle, which is held by a stand on at least one side, and a rotatable roll mount, which is oriented in parallel with the spindle, and which is mounted on the spindle. The roll mount is mounted on the spindle in a linearly displaceable manner using at least one linear bearing.

A film winding system is disclosed having a first winding station which is configured in a winding position to wind the film web into a film bale. A contact roller and a compensating roller are provided, wherein the contact roller is arranged adjacent to the first winding station in the winding position and is configured to guide the film web to the first winding station. The compensating roller is located before the contact roller in the direction of travel of the film web and is configured to guide the film web to the contact roller and to set a film tension. A first adjustment device is provided and configured to move the contact roller towards the winding station or away from the winding station, thereby enabling the setting of a specific contact pressure between the contact roller and the film bale. The first adjustment device comprises a slide system or an adjusting spindle.

A sheet conveyance device includes a conveyance roller having first and second end portions in a rotation axis direction, an open bearing supporting the first end portion, a frame supporting the open bearing, and a second end support portion supporting the second end portion. The open bearing includes a roller support portion supporting the conveyance roller and an open portion allowing the conveyance roller to be removed through the open portion from the roller support portion in a direction perpendicular to a rotation axis. The open bearing is movable from a first position, at which the conveyance roller is restricted from moving, to a second position at which the conveyance roller can move in the rotation axis direction. The second end portion is removable from the second end support portion by moving the conveyance roller from the second toward first end portion with the open bearing at the second position.

An unwinder for web material includes: a first and second reel holder, a dynamic storage device, a junction device arranged between the first or second reel holder and the dynamic storage device and configured to join an end portion of web material running out on the first reel to an initial portion of web material of the second reel, an actuator configured to pull the web material. The dynamic storage device includes: a plurality of first return rollers, a carriage mounted on a guide and free to move along the guide approaching or moving away from the first return rollers, a plurality of second return rollers mounted idly on the carriage. The return rollers define a zigzag path for the web material. The dynamic storage device includes a plurality of motorized shafts and each first return roller is mounted by means of two rolling bearings on a respective motorized shaft.

A roll accommodation unit includes: a roll support shaft; a pair of side walls; and a pair of roll bearings that are attached to the pair of side walls, recessed portions are formed at upper ends of the pair of side walls, the pair of rolling bearings are attached to the side walls at positions corresponding to bottoms of the recessed portions such that the rolling bearings project upward beyond inclined surfaces of the recessed portions, the roll support shaft includes a support shaft main body, and a pair of small-diameter portions that are provided at both ends of the support shaft main body, and the roll support shaft is supported with the small-diameter portions abutting on outer circumferential surfaces of the pairs of rolling bearings in a state in which the support shaft main body is located at an interval from the recessed portions.

A sheet conveying device includes a first conveyance roller, a sheet conveyance path, a second conveyance roller, and a pair of bearing portions. The first conveyance roller is provided in an apparatus main body. The sheet conveyance path has a guide surface that guides a sheet member in a sheet conveyance direction. The second conveyance roller is rotatably attached to the guide surface via a shaft and abuts on the first conveyance roller by a predetermined pressing force. The bearing portions are provided on the guide surface and support the shaft. Each bearing portion includes a concave groove portion and a bush member. The concave groove portion is formed on the guide surface such that a groove depth direction is perpendicular to the guide surface. The bush member is attached to the concave groove portion so as to be slidable in the groove depth direction and support the shaft.

The sheet conveyance apparatus includes a frame supporting first and second bearing portions, and a restricting portion. The frame supports the first and second bearing portions such that a movable amount with respect to the frame, in a direction along a sheet conveying direction, of the first bearing portion is larger than that of the second bearing portion. The restricting portion is provided with a predetermined gap from the first bearing portion in the direction along the sheet conveying direction, and configured to restrict the first bearing portion from moving in the direction along the sheet conveying direction in a case when the first bearing portion abuts with the restricting portion.
