摘要 |
An improved linear motor device is disclosed having a vibration reduction unit. The linear motor device can be applied to a copying machine. As a magnetic field forming device (36) receives reaction force and is moved, in the opposite direction to the movement of movable members (10a, 10b), vibration is not transmitted to a base frame (1). The magnetic field forming device is carried to a most suitable position for absorbing the vibration by a driving device (40) employing a pulse motor. A velocity reduction ratio in a velocity reduction mechanism of the driving device is set to be different from a velocity reduction ratio under an ideal condition in which frictional force is neglected. As a result, the magnet field forming device can be driven by a smaller pulse motor. <IMAGE> |
