A stapler, having a collateral punching function in addition to an original stapling function and being selectively used as a stapler or a punch as desired, is disclosed. In the stapler, a longitudinal base (10) has a staple forming die (16) at its front end portion and two parallel support walls (11) at its rear end portion. A punch hole (12) is formed on the top surface of the base (10) at a position between the two support walls (11), while a sheet insert slit (14) is formed between the two support walls (11) and the top surface of the base (10) so as to allow sheets of paper to be inserted into the slit (14) during a punching operation. A pressing lever (30) is hinged to the shaft holes (15) of the support walls (11) at its bearing holes (33) using a lever shaft (32) and is manually operated by a user so as to perform a desired stapling operation or a desired punching operation. A staple feeder (20) is hinged to the first shaft holes (31) of the lever (30). A punching plunger (40), having a cutting edge (41) at its lower end, is vertically positioned on the base (10) at a position between the two support walls (11) while being normally biased by a spring (43) upwardly. The plunger (40) thus comes into contact with the lower surface of the lever (30) at its top end and is vertically inserted into the punch hole (12) at its lower end portion during a punching operation. |
