A compact, electric, spring energized desktop stapler having a unitized housing providing both an external movable enclosure and a support frame for internal parts is disclosed. The internal power train is preferably elongated with the motor at the rear, a gear set toward the center, and low profile lever and power spring assembly at the front. The lever engages a striker with a normal upper rest position where the power spring is deflected and energized. A cam roller mounted to a final gear holds down the rear of the lever until the system is activated when the final gear rotates and the cam roller rolls off the end of the lever. In the unitized body, the base is pivotally attached to the body at the rear. A base lever selectively links to a cam roller or equivalent structure to move the body downward toward the base during a cycle.

A flat clinch assembly fits upon or within a base of a stapling device. The assembly preferably includes a slot with extended resiliently biased arms or toggles, where a rest position has the arms at or near a level of a working surface. An ejecting staple deflects and energizes the arms to cause the arms to rotate and create a clearance recess whereby points of the staple legs slide inward along the anvil. A restorative bias acting on the arms causes the arms to rebound to a rest position and to bend the legs upward. The legs thereby are normally pressed flat against the back sheet of a paper stack at the working surface. The arms or toggles are lightweight whereby the inertia of a fast-moving staple moves the arms or toggles. The toggle may include an upward facing staple leg guide channel

A stapling device includes an anvil leg, an anvil plate, a staple magazine, which can be pivoted relative to the anvil leg about a transverse axis, a driver for carrying out stapling through a gap at the front end of the staple magazine, and an actuation apparatus for acting upon the driver toward the anvil plate. The actuation apparatus has a solenoid and a striking pin for acting upon a driver anvil fixedly connected to the driver, the striking pin being movable by the solenoid. Between the gap and the transverse axis, the staple magazine is supported on the anvil leg by a magazine spring. The magazine spring is configured such that the staple magazine rests on the anvil leg or on the anvil plate due to a force of gravity acting on the staple magazine and overcoming a spring force of the magazine spring.

A staple apparatus can comprise a staple head movable in a first staple direction from a head retracted position to a head extended position. The staple apparatus can further comprise an indexing apparatus comprising an index biasing member and an indexing member. The indexing member can be positioned at least partially within an indexing area and biased with the index biasing member toward a member extended position relative to the indexing area. The indexing member can define a rung travel path and can further comprise an indexing tab comprising a ramp surface positioned to taper the rung travel path in the first indexing direction. The indexing tab can further comprise a shoulder positioned past at least a portion of the ramp surface in the first indexing direction. In further embodiments, a staple chain positioning apparatus can comprise a push member movable in an extension direction.
