Abstract
A desktop stapler having a feature for alignment of the anvil with the striker is disclosed. In one embodiment, a stapler body containing a striker is pivotably attached to a base. The pivoting rotation of the body causes a front-to-back motion of the striker over an anvil. A rib disposed at the back end of the body selectively pulls the back end of a linkage to the anvil backward as the body pivots downward to the stapling position. The anvil thus translates in relation to the body to maintain a close alignment of the striker over the anvil. The base assembly may include a cover plate slidable upon a base, wherein the cover plate includes the anvil. Another embodiment uses a tab that urges a staple track to be forcibly pulled open as the body is rotated away from the base.
