Claim:
A device for the placement of sheets for a printer, including at least one rotating drivable sheet conveyor, which is provided to accept or grip a front edge of a sheet and for the placement of the sheet on a stack of sheets after traversing a rotation path, and a sensor device for the detection of the attained stack height and the attained stack level, which has a sensor, which simultaneously functions as the holding-down element for the stack, which is lifted, mechanically controlled, from the stack, for the release of the stack, so as to place the next sheet on the stack; said device characterized in that; at least two sheet conveyors are provided in such a way that these several sheet conveyors can rotate around a common axis-independently of one another, and thus one of these sheet conveyors is ready to accept or detect the next sheet, if another one of these sheet conveyors is still occupied with the transport or the placement of a preceding sheet and that the sensor is coupled mechanically with several of these sheet conveyors.
