A low-electric-current-demand stapler is disclosed. The stapler has a frame upon which is mounted a fastener driver mechanism including a fastener driving blade and drive unit, a blade drive-control unit including spaced-apart frame pieces mounted on the frame, a rotary driven wheel mounted on the drive-control unit, and an electric motor powered transmission apparatus for transmitting the rotary motion of the motor to the driven wheel.

In a motor-driven fastener machine having a base, an anvil on the base, a fastener driving mechanism mounted for movement relative to the base, the improving comprising drive-control means also mounted on the base about pivot means for movement with respect to the base to cause the fastener driving mechanism to drive the fastener against the anvil; rotary drive means mounted on the drive-control means such rotary drive means including eccentric means carrying shaft means; follower arm means mounted between (1) the base about a second pivot means spaced from the first pivot means, and (2) the rotary drive means such arm means including eyelet means for surrounding and engaging the eccentric means; transmission means (66,63) connected to the rotary drive means (68) for causing the drive-control means (50) carrying such shaft means (62) to move through a cycle of movement including a reciprocating path (A); and fastener mechanism means (55) on the drive-control means (50) slidably engageable with the fastener driving mechanism (17, 43) which engagement means (55) causes at times the fastener mechanism (I7, 43) to be driven downwardly and at other times causes the drive-control means to move the fastener mechanism upwardly.
