Abstract
A stapler comprises a removable cassette, which contains a strip of staple blanks, and an advancing mechanism, which is arranged to advance the strip and which, to this end, has a feeding plate, which engages one flat side of the strip. The advancing mechanism comprises elements, which are arranged to interact with the removable cassette to move the feeding plate, during an initial phase of the cassette's removal from the stapler, to a neutral position, in which it has been disengaged from the strip, and to move the feeding plate, during a final phase of the reinsertion of the cassette or the insertion of a similar cassette into the stapler, to an engagement position, in which it engages the strip.
