A powered stapler includes a housing having a first housing portion and a second housing portion movably coupled to the first portion. The stapler is actuated by creating relative movement between the first and second housing portions. The second housing portion includes an elongated trigger member, that when moved relative to the first housing portion, actuates the powered stapler to drive a staple into a stack of sheets. The stapler is configured to be held in a single hand of the user and can be actuated by the user squeezing his or her hand while holding the stapler.

The invention claimed is: 1. A hand-actuated powered stapler having a front end adjacent to a staple ejection location and a rear end opposite the front end, the stapler comprising: an electrically operable staple drive mechanism; a housing at least partially surrounding the drive mechanism; and a trigger member pivotally connected to the housing at a point closer to the rear end of the stapler than to the front end of the stapler; wherein the stapler is actuated by creating relative movement between the trigger member and the housing. 2. The powered stapler of claim 1, wherein the stapler has an overall length measured from the front end to the rear end, and wherein the trigger member is pivotally connected to the housing at a location between a midpoint of the stapler's overall length and about seventy-five percent of the stapler's overall length. 3. The powered stapler of claim 1, wherein the stapler has an overall length, and wherein the trigger member has a length greater than fifty percent of the overall length of the stapler. 4. The powered stapler of claim 3, wherein the trigger member has a length of between about fifty percent of the overall length of the stapler and about seventy-five percent of the overall length of the stapler. 5. The powered stapler of claim 1, wherein the housing defines an opening exposing at least a portion of the drive mechanism, and wherein the trigger member is configured to substantially close the opening. 6. The powered stapler of claim 1, wherein the housing includes a first housing portion, and wherein the trigger member defines a second housing portion at least partially surrounding the drive mechanism such that, the first and second housing portions substantially enclose the drive mechanism. 7. The powered stapler of claim 1, wherein the trigger member is at least partially covered with a resilient membrane. 8. The powered stapler of claim 1, further comprising a mode selection switch operable to selectively permit actuation of the stapler upon movement of the trigger member with respect to the housing. 9. The powered stapler of claim 1, further comprising a switch electrically connected to the drive mechanism, and wherein movement of the trigger member with respect to the housing activates the switch to actuate the drive mechanism. 10. The powered stapler of claim 9, wherein the trigger member includes a post configured to engage a contact plunger on the switch to activate the switch, and wherein movement of the trigger member with respect to the housing engages the post with the contact plunger. 11. The powered stapler of claim 1, wherein the trigger member has a length such that a user who grasps and squeezes the stapler will actuate the stapler without the need to accurately position a finger on an actuation button. 12. A hand-actuated powered stapler comprising: an electrically operable staple drive mechanism; a housing at least partially surrounding the drive mechanism; and a trigger member movably coupled to the housing; wherein the stapler is actuated by creating relative movement between the trigger member and the housing; and wherein the stapler has an overall length, and wherein the trigger member has a length greater than fifty percent of the overall length of the stapler. 13. The powered stapler of claim 12, wherein the trigger member has a length of between about fifty percent of the overall length of the stapler and about seventy-five percent of the overall length of the stapler. 14. The powered stapler of claim 12, wherein the housing defines an opening exposing at least a portion of the drive mechanism, and wherein the trigger member is configured to substantially close the opening. 15. The powered stapler of claim 12, wherein the housing includes a first housing portion, and wherein the trigger member defines a second housing portion at least partially surrounding the drive mechanism such that, the first and second housing portions substantially enclose the drive mechanism. 16. The powered stapler of claim 12, wherein the trigger member is at least partially covered with a resilient membrane. 17. The powered stapler of claim 12, further comprising a mode selection switch operable to selectively permit actuation of the stapler upon movement of the trigger member with respect to the housing. 18. The powered stapler of claim 12, further comprising a switch electrically connected to the drive mechanism, and wherein movement of the trigger member with respect to the housing activates the switch to actuate the drive mechanism. 19. The powered stapler of claim 18, wherein the trigger member includes a post configured to engage a contact plunger on the switch to activate the switch, and wherein movement of the trigger member with respect to the housing engages the post with the contact plunger. 20. The powered stapler of claim 12, wherein the trigger member is pivotally connected to the housing. 21. The powered stapler of claim 20, wherein the overall length of the stapler is measured from a front end of the stapler to a rear end of the stapler, and wherein the trigger member is pivotally connected to the housing at a location between a midpoint of the stapler's overall length and about seventy-five percent of the stapler's overall length. 22. A hand-actuated powered stapler comprising: an electrically operable staple drive mechanism; a housing at least partially surrounding the drive mechanism; and a trigger member movably coupled to the housing; wherein the stapler is actuated by creating relative movement between the trigger member and the housing; and wherein the housing includes a first housing portion, and wherein the trigger member defines a second housing portion at least partially surrounding the drive mechanism such that, the first and second housing portions substantially enclose the drive mechanism. 23. The powered stapler of claim 22, wherein the trigger member is at least partially covered with a resilient membrane. 24. The powered stapler of claim 22, further comprising a mode selection switch operable to selectively permit actuation of the stapler upon movement of the trigger member with respect to the housing. 25. The powered stapler of claim 22, further comprising a switch electrically connected to the drive mechanism, and wherein movement of the trigger member with respect to the housing activates the switch to actuate the drive mechanism. 26. The powered stapler of claim 25, wherein the trigger member includes a post configured to engage a contact plunger on the switch to activate the switch, and wherein movement of the trigger member with respect to the housing engages the post with the contact plunger. 27. The powered stapler of claim 22, wherein the trigger member has a length such that a user who grasps and squeezes the stapler will actuate the stapler without the need to accurately position a finger on an actuation button. 28. The powered stapler of claim 22, wherein the trigger member is pivotally connected to the housing.
