Abstract
A stapler includes a driver-and-clincher mechanism for operating a driver and a clincher such that the driver-and-clincher operating mechanism operates the driver until the driver nearly reaches a bottom dead point thereof during a first half downward movement of an operating handle and then the driver-and-clincher mechanism operates the clincher during a latter half movement of the operating handle.
