A sheet feeding apparatus includes a storage portion, a sheet supporting portion, a feed portion, a drive portion configured to output driving force that lifts the sheet supporting portion, a rotation shaft rotatably supported by the storage portion and including an engaging portion disposed on one end side in an axial direction, the engaging portion being configured to engage with the drive portion, a pressing portion fixed to the rotation shaft and configured to press the sheet supporting portion from below when the rotation shaft is rotated by the drive portion, and a rotary damper disposed so as to join with the rotation shaft on another end side of the rotation shaft and configured to reduce rotary motion of the rotation shaft.

A sheet conveying apparatus includes a rotating member to covey a sheet and a drive transmission having a first, gear in a first engaging portion, a second gear in a second engaging portion, and an urging member. In a state where the first engaging portion and the second engaging portion are engaged with each other and the first gear is rotating in a first direction, a first surface of the first engaging portion transmits a driving force of a driving source from the first gear to the second gear. The first surface is inclined so that either engaging portion can retract, in the direction against the urging force of the urging member, to disengage with the other engaging portion while the first engaging portion rotates. A direction of twist of helical teeth in the first gear is configured to generate an axial force with respect to the urging direction.

A sheet conveying device includes a supporting shaft, a rotating unit removable from an installation portion, a movable shaft, and an interlocking device. The rotating unit includes first and second ends, a holding member that holds a rotating body that conveys a sheet. The supporting shaft supports the rotating unit at the first end in an axial direction of the rotating body. The movable shaft is movable in the axial direction and supports the second end. The interlocking device moves the movable shaft per the rotating unit movement. Where the rotating unit is to be moved at a moving amount towards a side in which the rotating unit separates from the supporting shaft as part of removing the rotating unit from the installation portion, the interlocking device moves the movable shaft in the axial direction at a moving amount that is larger than the moving amount the rotating unit.

A sheet conveyance apparatus includes a cover unit, a base unit, a roller unit configured to be detachable from the cover unit, and comprising a roller configured to convey the sheet along a conveyance path and a holder comprising an arm portion configured to extend in a width direction orthogonal to a sheet conveyance direction, a cam configured to swing the holder by rotating, and a cover member configured to be openable and closable with respect to the cover unit and configured to cover at least a portion of the arm portion against the conveyance path in a closed state, the cover member being opened by being pressed by the arm portion in a case where the roller unit is detached from the cover unit.

A rewinding machine winds a web material into a log about a core. The web material to be wound is directed about a rotating winding drum. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the core is inserted and through which the web material is directed. A surface of the continuous loop opposite the winding drum across the nip is configured to move in a direction generally opposite of the winding drum for winding the web material about the core. A rider roll defines a winding space with the winding drum and the continuous loop. The rider roll is movable relative to the continuous loop and the winding drum to allow for an increase in a diameter of the log in the winding space during winding of the web material about the core.

A feeding device includes a loading unit at which a printing medium is loaded, a roller that transports the printing medium, a transport path member at which the roller is disposed, the transport path member constituting a transport path on which the printing medium is transported, a drive source that generates a drive force that rotates the roller, a clutch that is movable between a coupling position at which the drive force is transmitted to the roller, and a release position at which the drive force is not transmitted to the roller, and an operation unit for operating the clutch, in which the operation unit is provided at a position, on the transport path member, facing the printing medium being transported by the roller, and the roller is removable from the transport path member when the clutch is located at the release position.

A method for arranging elongated elements in a process for building tyres for vehicle wheels, including: arranging a first winding support with a first elongated element of a first type wound on the first winding support; arranging a second winding support with a second elongated element of a second type different from the elongated element of the first type wound on the second winding support; arranging a coupling device including a first coupling body and a second coupling body rotatable with respect to one another about a rotation axis; and arranging the first winding support on the first coupling body and the second winding support on the second coupling body.

A sheet feeding apparatus includes a conveyance roller, a drive input shaft, a joint, a first engaging portion, a first engaged portion, a second engaging portion, and a second engaged portion. When viewed in an axial direction of the joint, an angle formed by a first straight line and a second straight line is within a range of 80 degrees or greater and 100 degrees or smaller, the first straight line passing through the first engagement position and a center of rotation of the drive input shaft, the second straight line passing through the second engagement position and a center of rotation of the retard shaft.

A separator cutting apparatus includes: a fixing part configured to fix temporarily the electrode assembly; a cutter supporting part disposed above the fixing part; a cutter part disposed below the cutter supporting part, and configured to cut a separator among the electrode assembly temporarily fixed to the fixing part; and a spring part configured to connect elastically the cutter supporting part and the cutter part to each other, and return the cutter part to an initial position after cutting the separator; the spring part includes a spring bush coupled to a supporting shaft provided in the cutter supporting part and the cutter part, respectively, a spring holder integrally coupled to the spring bush, and a spring that expands and contracts according to the elevation of the cutter part by coupling both ends to the spring holder, and the spring holder and the spring bush are made of a non-metallic material.

A thick document conveying device includes a paper pickup mechanism. The paper pickup mechanism has a pick roller base, a pick roller axle, a pick roller, a switching assembly, a first universal coupling, a driving mechanism, a second universal coupling, a bearing and a gear. The pick roller axle and the pick roller are located in the pick roller base. The switching assembly is located under the pick roller base. The first universal coupling is connected to the pick roller axle. The driving mechanism is sleeved on the first universal coupling. The second universal coupling is connected to the driving mechanism. The bearing is connected to the driving mechanism. The gear is connected to the bearing. As described above, both a thick document and a thin document can be adapted.
