A combination manual staple gun and a cap feeding device comprises a staple gun having a cap feeding device attached thereto. Interconnected between the staple gun and the cap feeding device is an actuating linkage. The actuating linkage is connected to a movable member of the staple gun and is driven in response to the actuation of the staple gun or in response to the staple gun being pressed against a surface for the purpose of shooting a staple into the surface. More particularly, the cap feeder device includes a container for containing a stack of caps and a cap feeder or feeding mechanism for engaging one cap at a time and directing the cap towards a cap ejection area associated with a staple gun in response to the connecting or actuating linkage being actuated.
