ABSTRACT:
A flat-type stapler is provided which can fasten a large number of sheets of paper with a small force and in a smooth fashion. The stapler includes a base portion, a magazine portion, a push-down member, handle supporting members, and a handle portion. The handle portion causes the push-down portion to descend by virtue of the principle of the lever with the handle shaft made to act as a movable fulcrum. A portion of the handle may be used to apply force, and the connecting shaft may be used as a point of action.
