ABSTRACT:
A stapler device having a magazine assembly for a staple supply comprising a frame structure fixed to the housing of the stapler device. The frame structure has generally upwardly facing concave surfaces for supporting the staple supply roll at spaced positions beneath the central periphery thereof and generally upwardly facing surfaces for supporting the end portion extending from the roll at positions beneath the central extent thereof leading to the guide path in the stapler device. A cover is pivoted to the frame between opened and closed positions and includes a curved peripheral wall and a pair of marginal side walls along the curved edges of the peripheral wall. A pair of transversely spaced locking elements are fixed with respect to the frame structure and the cover has locking surfaces adjacent the forward end portion thereof for engaging the locking elements to retain the cover in its closed position. The material of the cover and the configuration of its peripheral and side walls being such as to enable the forward end portion of the cover to be resiliently deflected in a direction toward the rearward pivoted end thereof so as to enable the locking surfaces of the cover (1) to be released from the locking elements to allow the cover to be moved out of its closed position into its open position and (2) to be engaged with the locking elements when the cover is moved from its open position into its closed position.
