Abstract: Embodiments include a stapler with a built-in staple remover, the staple remover movable between a non-operational position where it is retracted in a stapler body of the stapler and locked by a locking device and an operational position where it is partly extended from the stapler body, the staple remover being acted upon by a first elastic unit which is tensioned when the staple remover is in the non-operational position and which pushes the staple remover to the operational position when the locking device is released in the non-operational position.

Abstract: A stapler for stapling together a workpiece, primarily a sheaf of papers, in which the stapler comprises a stapling unit and an anvil, which interacts with the stapling unit and on which the workpiece is placed, and against which stapling is performed, which stapling unit and an anvil are, driven relative to each other in a reciprocating stapling movement, during which movement stapling takes place, the stapling unit comprises a frame and a staple cassette which houses staple blanks and which is exchangeable, and which is detachably connected to the frame by attachment devices, and the staple blanks are fed one by one to an outlet channel by a feeding device incorporated in the stapler.

Abstract: A stapler (1) using staples for stapling together a workpiece (5), particularly a sheaf of papers, which stapler comprises a base part (3) against which the workpiece is placed, a magazine part (4) in which the staples are stored and a built-in staple remover arrangement (7) comprising a staple remover (8) which is movable between a non-operational first position where it is re-tracted in the stapler body (2) and locked by a locking device (9) and an operational second position where it is partly extended from the stapler body, the staple remover (8) being acted upon by a first elastic means (10) which is tensioned when the staple remover is in a non-operational position and which pushes the staple remover to the extended position when the locking device (9) is released in the non-operational position.
