Abstract
A portable motor-driven staple machine comprises: a trigger operation detecting switch 5 which is turned on and off by a trigger lever 3; a contact detecting switch 25 which is turned on and off by a contact arm 23; a cycle completion detecting switch 21 which is turned on and off by a plunger 17; and a mode change-over switch for selecting a single cycle operation mode or a continuous operation mode. Those switches are connected to a control circuit 26. When the trigger lever 3 is operated with the contact detecting switch 25 in 'off' state, a timer section in the control circuit 26 counts clock pulses so that when it is detected that a predetermined period of time has passed, the switch 'on' signal of the trigger operation detecting switch 5 is cut off. In the case where the continuous operation mode is selected, an automatic power interrupting function is released, so that the motor 7 is continuously driven; that is, staples are continuously driven into the object until the trigger operation detecting switch 5 or the contact detecting switch 25 is turned off.
