A suction conveyor device comprising a suction arrangement having a suction side on which low pressure is generated, continuously rotating flexible conveying means made of flexible flat material having holes, an inner side enabling the conveying means to move along the suction side, and an outer side for receiving flat items in the active area of the suction side, where the conveying means moves in the transporting direction, the suction arrangement and the conveyor means designed with a transport path width in the active range perpendicular to the transporting direction. The conveying means includes continuously circulating individual, single-piece, flexible conveying means, both lateral edges thereof extending in the transporting direction at a distance from each other being at least the same as the total width of the transport path such that the individual, single-piece flexible conveyor means extend over the total width of the transport path.

The invention relates to a device for receiving, transporting, and dispensing film bags, comprising a film bag magazine with multiple parallel magazine shafts and two circulating conveyor belt devices which can be driven independently of each other and which comprise film bag receiving areas arranged thereon, said conveyor belt devices circulating about two common axes. The two axes are designed to be drivable independently of each other, and each axis drives one of the two conveyor belt devices. The invention further relates to a method for receiving, transporting, and dispensing film bags by means of the device for receiving, transporting, and dispensing film bags.

A sheet feeding unit, attached to a sheet feeding apparatus that feeds a sheet, includes an endless belt, first and second rotary members, and a holding device. The endless belt contacts a sheet stacked on a stacking device to feed the sheet. The first and second rotary members contact an inner periphery of the endless belt to support the endless belt. The second rotary member faces, via the endless belt, a separation device that separates the sheet from the endless belt. The holding device holds the first and second rotary members. The endless belt includes protruding and depressed portions on the inner periphery. The second rotary member includes protruding and depressed driving portions that mesh with the protruding and depressed portions to transmit a driving force to the endless belt to, in turn, rotate the endless belt to feed the sheet in contact with the endless belt.

An image forming apparatus includes: a belt conveyance device that corrects leaning of an endless belt member, the belt conveyance device being detachably attachable to an apparatus body of the image forming apparatus; a first guiding portion that supports a first guided portion provided in a frame member supporting rotatably a first roller on which the belt member is laid under tension and guides the belt conveyance device attached to or detached from the apparatus body; and a second guiding portion that supports a second guided portion provided in a steering unit supporting rotatably a second roller on which the belt member is laid under tension, releases the second guided portion at an attachment position of the belt conveyance device to the apparatus body, and guides the belt conveyance device attached to or detached from the apparatus body.

The two axes are designed to be drivable independently of each other, and each axis drives one of the two conveyor belt devices. The invention further relates to a method for receiving, transporting, and dispensing film bags by means of the device for receiving, transporting, and dispensing film bags.

A stretching roller for stretching an intermediate transfer belt is tiltably disposed, and includes a sliding ring unrotatably disposed at both axial ends of a roller portion. The intermediate transfer belt winds and slidably rotates around the sliding ring. The sliding ring has a tapered portion inclined so that the outer diameter increases toward the axial end side of the stretching roller. The tapered portion is formed so that the inclination angle with respect to the central axis of the stretching roller differs at least in part in the circumferential direction.

A sheet feeding unit, attached to a sheet feeding apparatus that feeds a sheet, includes an endless belt, first and second rotary members, and a holding device. The endless belt contacts a sheet stacked on a stacking device to feed the sheet. The first and second rotary members contact an inner periphery of the endless belt to support the endless belt. The second rotary member faces, via the endless belt, a separation device that separates the sheet from the endless belt. The holding device holds the first and second rotary members. The endless belt includes protruding and depressed portions on the inner periphery. The second rotary member includes protruding and depressed driving portions that mesh with the protruding and depressed portions to transmit a driving force to the endless belt to, in turn, rotate the endless belt to feed the sheet in contact with the endless belt.

A sheet transport system comprising an endless carrier belt that has a predetermined stiffness and is arranged to carry the sheets towards an end of a conveyer path where the sheet is separated from the carrier belt by passing this belt around a separating member that has a predetermined curvature, wherein the carrier belt runs in parallel with an endless conveyer that has a larger stiffness than the carrier belt and, at the end of the conveyer path, has a smaller curvature than the separating member.

A transporting device includes a first belt, a second belt that transports a medium in cooperation with the first belt, a first shifting member that shifts the first belt in a width direction of the first belt, a second shifting member that shifts the second belt in a width direction of the second belt, a rotatable member that is rotatable around its own axis, and a forming member provided across the first belt and the second belt from the rotatable member and that forms a nip between the first and second belts in cooperation with the rotatable member. The rotatable member and the forming member cooperate to form the nip at a pressure ratio lower than about 1. The pressure ratio is obtained by dividing a pressure applied to each of two axial ends of the rotatable member by a pressure applied to an axial center of the rotatable member.

An apparatus and a corresponding method for singling value documents, in particular banknotes, includes a support means and a conveyor belt for picking a single value document from a stack of value documents lying on the support means. The singling device has a positioning device by which at least a portion of the conveyor belt can be moved back and forth relative to the support means between a first position and a second position. In the first position the conveyor belt cannot touch the stack lying on the support means. In the second position the conveyor belt can touch the lowermost value document of a stack lying on the support means and pick the former from the stack at least partially.
