Abstract An electric stapler (10) is disclosed as including a stapling head (12) with a driver (28), an intermediate magazine (14) for carrying staples each with two legs, a base part (16) carrying two anvils (44), cams (24), and eccentrically mounted wheels (52), in which the stapling head (12), intermediate magazine (14) and base part (16) are movable relative to one another, the eccentrically mounted wheels (52) are rotatable to move the stapling head (12) and intermediate magazine (14) relative to each other and relative to the base part (16) whereby the driver (28) of the stapling head (12) drives a staple away from the magazine (14), and the cams (24) are rotatable to move a movement transmission assembly (30) to move the anvils (44) to bend the legs of the staple. ## Claims ### Claim 1 A stapler comprising: a stapling head with a driver, a magazine adapted to carry at least one staple with two legs, a base part carrying at least two anvil members, a movement transmission assembly for moving said anvil members to bend said legs of said staple, and at least one actuator, wherein said stapling head, said magazine and said base part are movable relative to one another, wherein said actuator is movable from a first position to a second position to move said stapling head and said magazine relative to each other and relative to said base part such that the driver of said stapling head drives said staple away from said magazine, said actuator being movable from said first position to said second position by rotation in a first direction, wherein said actuator is movable from said second position to a third position to move the movement transmission assembly to move said anvil members to bend said legs of said staple, said actuator being movable from said second position to said third position by continued rotation in said first direction, wherein said actuator is movable from said third position back to said first position, by continued rotation in said first direction, wherein said actuator is rotatable in said first direction about an axis fixed relative to said stapling head. ### Claim 2 (depends on 1) A stapler according to claim 1 wherein said actuator includes at least one cam member and/or at least one wheel member. ### Claim 3 (depends on 1) A stapler according to claim 1 wherein said actuator is movable from said third position to a fourth position to move said stapling head and said magazine away from said base part. ### Claim 4 (depends on 1) A stapler according to claim 1 wherein said stapler is electrically operated. ### Claim 5 A stapler comprising: a stapling head with a driver, a magazine adapted to carry at least one staple with two legs, a base part carrying at least two anvil members, a movement transmission assembly for moving said anvil members to bend said legs of said staple, and at least one actuator, wherein said stapling head, said magazine and said base part are movable relative to one another, wherein said actuator is movable from a first position to a second position to move said stapling head and said magazine relative to each other and relative to said base part such that the driver of said stapling head drives said staple away from said magazine, wherein said actuator is movable from said second position to a third position to move the movement transmission assembly to move said anvil members to bend said legs of said staple, and, wherein said movement transmission assembly comprises a first part, a second part and a third part which are pivotally connected with and pivotally movable relative to one another. ### Claim 6 (depends on 5) A stapler according to claim 5 wherein said second part of said movement transmission assembly is pivotally movable about an axis fixed relative to said base part. ### Claim 7 (depends on 5) A stapler according to claim 5 wherein, during movement of said actuator from said second position to said third position, said first part of said movement transmission assembly moves in a first direction and said third part of said movement transmission assembly moves in a second direction which is substantially opposite to said first direction. ### Claim 8 (depends on 7) A stapler according to claim 7 wherein movement of said third part of said movement transmission assembly in said second direction moves said anvil members to bend said legs of said staple. ### Claim 9 (depends on 5) A stapler according to claim 5 wherein said stapler is electrically operated. ### Claim 10 (depends on 5) A stapler according to claim 5 wherein said actuator is movable from said third position to a fourth position to move said stapling head and said magazine away from said base part. ### Claim 11 (depends on 10) A stapler according to claim 10, further including a spring member which, during said movement of said stapling head and said magazine away from said base part, is adapted to move said movement transmission assembly, whereupon said first part of said movement transmission assembly moves in said second direction and said third part of said movement transmission assembly moves in said first direction. ### Claim 12 (depends on 5) A stapler according to claim 5 wherein said first part of said movement transmission assembly is directly connected with said second part of said movement transmission assembly and said third part of said movement transmission assembly is directly connected with said second part of said movement transmission assembly.
