A conveying body that can attract and peel-off a recording medium by a simple mechanism, and an image forming device using the conveying body are provided. One end portions of through-holes of a drum are blocked by a blocking member, and a suction member and a blowing-out member are provided at other end portions of the through-holes. Due to a suction pump being operated and suction force being generated within the through-holes via a suction port of the suction member, the suction force passes through the through-holes and acts on long grooves of an outer peripheral surface of the drum, and a sheet can be attracted reliably to the outer peripheral surface of the drum. Further, because air is blown-out from the blowing-out member by operation of the suction pump, a leading end portion of a sheet can be reliably peeled-off from the outer peripheral surface of the drum.

When the operation of an electronic component conveying apparatus is to be stopped, application of a negative pressure to through holes is stopped, and a compressed air blowing mechanism blows compressed air from an exhaust nozzle with a pressure greater than a pressure applied during the operation of the electronic component conveying apparatus. Accordingly, an air curtain is generated at opening portions of the through holes on the guide member side, and the air curtain prevents electronic components from entering the through holes. The electronic components remaining in the through holes located downstream of the position of the exhaust nozzle in a conveying direction are conveyed to a measurement section so as to enable measurement of the characteristics thereof, and then discharged by a discharging mechanism in a discharge section. Thereafter, rotation of a conveying member is stopped.

A sheet advancing over a transport plane by pairs of transport rollers is rotated through an angle of 90.degree. by retaining the sheet at a point of rotation coupled with the releasing of one of the transport roller pairs so that only the other transport roller pair exerts a torque on the sheet. By disposing the other of the transport roller pairs exerting the torque somewhat downstream of the center of rotation, the sheet is maintained taut during rotation.

To turn through 90.degree. sheets passing at a rapid rate over a roller conveyor in a horizontal plane, a device is proposed which comprises a pair of rollers entrained in rotation at different speeds and spaced apart from each other and from a longitudinal guide on the conveyor transversely with respect thereto. Each of the rollers has its rotation axis inclined with respect to the normal on this guide, by a specified angle which is greater for the roller which is closest to the guide and the rotation speed of which is the smaller. Each of the rollers has its periphery in contact with a support ball or with the lower face of a sheet during its passage, substantially in said transport plane.

There is provided a device and a method for turning flat articles, more particularly letter envelopes, flat bags or the like. The article is first moved out of its direction of conveyance into a curvilinear path, whereafter--without stopping in its original direction of conveyance--it is moved into a curvilinear path in a new direction until finally advancing onwards in its original direction of conveyance.

A stack support rotating about an upright axis is arranged beneath a discharge station of a delivery conveyor for the imbricated formation. The stack support and at least the discharge station of the delivery conveyor are adjustable in height in relation to one another. In order to increase the storage capacity of the spiral-layered coiled stack being formed, respectively in order to reduce its height for the same content, a drive mechanism is provided to periodically displace the discharge station of the delivery conveyor and the axis of rotation of the stack support relative to one another periodically and alternatingly toward and away from one another. A spiral-layered coiled stack thus forms in which each layer of the coil consists of a flat spiral preferably comprising a plurality of spiral windings progressing from the interior to the exterior and from the exterior to the interior in alternate layers.

A platen conveyance device includes a first conveyance path, a platen supporter, a second conveyance path, and a positioner. The first conveyance path is configured to convey a platen to a pretreatment device. The platen supporter is configured to support the platen conveyed by the first conveyance path. The second conveyance path is provided with the platen supporter. The second conveyance path is configured to convey the platen supporter to a printer. The positioner is configured to position the platen supported by the platen supporter at a prescribed printing position in a first direction in a horizontal direction.

An apparatus for forming sheet material assemblages includes a plurality of pockets which are movable past a plurality of sheet material feeders. Each of the pockets includes a sheet material support which is movable between any one of a plurality of closed positions and an open condition. When the sheet material support is in a closed position, it blocks the lower end portion of the pocket and supports sheet material in the pocket. When the sheet material support is in the open condition, it is ineffective to block the lower portion of the pocket so that the sheet material assemblage can move out of the pocket through the lower end portion of the pocket. An actuator is provided to move the sheet material support from the open condition to a closed position. The sheet material support is connected with side portions of the pocket by a four bar linkage. A clutch assembly in the four bar linkage is operable from an engaged condition to a disengaged condition to release the sheet material support for movement from a closed position.
