A stapling device has a stapler and a staple wire cassette detachably attached directly thereto, in which the leading end of the wire emerging from the staple wire cassette terminates directly in the working region of the stapler. The stapler has a base member serving as a staple-forming and holddown element, on which a driver and a sleeve are guided linearly so as to engage in telescoping fashion within one another, and are movable perpendicular to the upper side of a sheet stack. Compression springs of different spring forces, having the same working direction, engage on the base member, the driver, and the sleeve. The stapler is acted upon by a drive system which is movable in the working direction of the compression springs. The compression springs are associated with the base member, the driver, and the sleeve, and arranged in preloaded fashion thereon, in such a way that upon actuation of the stapler, a force-controlled drive occurs in an operationally correct sequence.
