ABSTRACT:
An electric stapler wherein a guide cylinder is fixedly disposed on a base having a groove for bending a driven staple in such a way as to form a slit for inserting papers to be stapled, and in the guide cylinder is disposed a vertically movable block having at its lower end a downwardly projecting blade for driving the staple toward the staple bending groove. The block is always given a downward pull by springs. A working arm is swingably supported by a shaft fixedly disposed at a position spaced-apart from the guide cylinder, the arm being pivotally secured at one end to an upper part of the vertically movable block and having at its other end a pressure receiving portion. There is provided a damper whereby in the state before the staple driving operation, the pressure receiving portion is pressed down against the force of the springs to retain the staple driven blade of the block at its raised-up position, and when a staple is pushed out, the pressing hold on the blade at its raised-up position is released. The operation of the damper is controlled by a motor powered by a battery.
