Abstract: A stylus support portion moveable in an X direction is arranged separate from a fixed portion. A plate spring has a first end fixated to an end portion of the stylus support portion in an X (+) direction, a second end fixated to the fixed portion, and a principal surface facing the X direction. A plate spring has a first end fixated to an end portion of the stylus support portion in an X (−) direction, a second end fixated to the fixed portion, and a principal surface facing the X direction. A first permanent magnet is provided on the end portion of the stylus support portion in the X (+) direction. A second permanent magnet is provided on the end portion of the stylus support portion in the X (−) direction. A third permanent magnet is provided to the fixed portion so that a magnetic force in the X direction acts on an area between the first permanent magnet and the third permanent magnet. A fourth permanent magnet is provided to the fixed portion so that the magnetic force in the X direction acts on an area between the second permanent magnet and the fourth permanent magnet.

Abstract: An optical encoder includes a scale having bar-like scale marks; a detection head having a light source fiber emitting coherent light at the scale and a photoreceiver fiber receiving light reflected off the scale; electronic components connected to the detection head via the light source fiber and the photoreceiver fiber; and a protector covering the scale marks at a predetermined distance from the scale marks. The protector is a member configured with light-transmissive material and includes a top surface that is inclined with respect to a principal surface of the scale.

Abstract: A probe includes a movable plate to which a stylus capable of contacting a measurable object is mounted, the movable plate displaceable in an X direction; a static plate arranged to overlap with the movable plate; a counter plate facing the movable plate and the static plate; an elastic movable side connection plate, the movable side connection plate connecting the counter plate at at least three places with each of a first end connector positioned toward a first end of the movable plate in the X direction and second end connectors positioned toward a second end in the X direction; and a static side connection plate which connects the static plate and the counter plate. An entire length of the first end connector in a Y direction orthogonal to the X direction is the same size as the entire length of the second end connectors in the Y direction.
