Abstract
A contact member is supported on the support shaft. A force sensor is coupled to the support shaft. A movable member is coupled to the force sensor. The pressure apparatus allows the movable member to cause the axial movement of the support shaft. A first guide serves to guide the axial movement of the support shaft. The first guide is supported on the support member. The support member stands still during the movement of the movable member. Accordingly, the movement of the movable member is restrained in the axial direction. The contact member is thus prevented from suffering from a swinging movement around the force sensor. Servo control of a higher frequency bandwidth can be applied to the movement of the contact member. The contact member moves at a higher velocity. Occurrence of resonance is still avoided in the contact member. The tact time can be shortened.
