ABSTRACT:
The invention relates to a cassette for receiving a stack of sheets, with a pressing element which bears against a first end face of the stack of sheets and is movable in the pressing direction, with a drive motor for displacing the pressing element so that a second end face the stack of sheets facing away from the pressing element can be brought to bear against extracting elements of a sheet extracting device, and with a measuring device for determining the pressing force of the stack of sheets against the extracting elements an output signal of the measuring device serving for controlling the drive motor in order to generate a predetermined pressing force. The stack of sheets and the pressing element are arranged in a slide which is accommodated in the cassette movably in the direction of displacement of the pressing element, the pressing element being displaceable with respect to the slide by the drive motor. The slide is pressed by a displacement-dependent force in the direction of the extracting elements.
