A stapler apparatus is disclosed as having a base 1 and a pivotal staple magazine lever 2 movably related toward each other during a stapling operation upon a set of sheets, the magazine member being provided at an end thereof with an anvil member 3, the anvil member and the stapling dispensing means being adapted to cooperate to permit individual ones of the staples to drive against the anvil member, to drive the staple legs through the sheets, and to deform the legs during a stapling operation when the base and magazine member are moved toward each other. The improvement includes a plurality of stop members 5, selectably movable into a position between the base and the magazine lever and being arranged to limit the relative movement therebetween and control the bending of the legs of the staple. Each of the stop elements 5a, 5b, 5c, and 5d have different limiting effects upon the lever action of the magazine toward the anvil 3.
