<p><P>PROBLEM TO BE SOLVED: To ensure certainty of switching and to improve stability while maintaining the basic constitution of an electric gun. <P>SOLUTION: The electric gun is constituted to drive a movable member of an air cylinder device in a retreating direction by a motor and to control driving of the motor by trigger operation. A driving part 22 of the motor 30 has a sector gear 27 meshed with a rack 25 provided on the movable member 15 side and extended along the moving direction, and a cam 33 coaxial with the sector gear 27. A switch 40 has a fixed switch part 42 and a movable switch part 41 openable/closable by parallel displacement and rotary motion relative to the fixed switch part 42. A communicating element 35 is equipped to allow the motor 30 and the switch 40 to communicate with each other and to switch into a position to separate the movable switch part 41 from the fixed switch part 42 by the cam 33. The position of the communicating element 35 is switched by the rotation of the cam 33 to allow the parallel displacement or rotary motion of the movable switch part 41. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
