US Patent 9844865 Driver tool

A driving tool includes a first cylinder that generates compressed air by reciprocating movement of a first piston slidably disposed therein. A longitudinal direction of the first cylinder intersects a longitudinal direction of a second cylinder and extends alongside a magazine that feeds fasteners onto an axis of movement of a driving part of a second piston. The first piston reciprocally slides in a direction that extends alongside the magazine. A tool handle is disposed on the side of the first cylinder that is opposite from the magazine in the direction of the axis of movement.
