Abstract
For rotating a flat object, a rotor is provided with a transport element for engaging an object in the rotor. A transmission element is coupled to the rotor. Between the transmission element and the transport element of the rotor, there is a transmission for causing the transport element to rotate relative to the rotor in response to rotation of the transmission element relative to the rotor. As a coupling structure between the rotor and the transmission element is arranged for retaining the transmission element relative to the rotor when rotation of the rotor is allowed, and for releasing rotation of the transmission element relative to the rotor when a switch is made to retaining the rotor, a fast, friction-low operation is enabled.
