A nail driver for driving nails into a receiving surface comprises a housing with a release member movable upwardly and downwardly in the housing having a lower end which is engageable with the receiving surface. A nail guide channel is defined in the housing and it is arranged in association with a magazine for feeding nails into the channel in succession. A nail driver bar is movable upwardly and downwardly in the channel over the nail. A compression spring is engaged between the lower end of the release member and the nail driver so that when the release member is pressed against a surface, it may move upwardly against the force of the compression spring. The control mechanism is actuated by displacement of the release member to effect driving of a windup drum for a drive tape which is wound around the drum and connected at its free end to the upper end of the nail driver. The downward movement of the striking bar to drive the nail into the surface effects a movement on the release member so that it lifts the housing to permit the control connection to the winding drum to stop the winding drum after it is rotated back to raise the driving bar back to its starting position.
