Abstract

The present invention provides an apparatus for measuring a step difference and an inclination angle difference between a first surface and a second surface which are to be measured, comprising: a first contacting member installed for being capable of rotating in accordance with the inclination of a first surface of an object to be measured on which the first contacting member contacts; a second contacting member apart from the first contacting member in the longitudinal direction installed for being capable of rotating in accordance with the inclination of a second surface to be measured on which the second contacting member contacts; a case for rotatably supporting the first contacting member and the second contacting member; a first measuring means for measuring a first rotational angle between the first contacting member and the case when the first contacting member contacts on the first surface; and a second measuring means for measuring a second rotational angle between the second contacting member and the case when the second contacting member contacts on the second surface; wherein the measuring apparatus enables to measure the step difference, the inclination angle difference, and straightness between the first surface and the second surface from the first rotational angle and the second rotational angle, without rotating or moving any one of the first surface, the second surface, and the apparatus.
