Abstract: A surface roughness measuring unit according to the present invention includes a contact pin unit having a contact pin and a displacement detector, the contact pin being provided so as to project and retract through a through-hole of a skid and scanning and moving along a surface of a work piece, the displacement detector detecting displacement of the contact pin in a direction perpendicular to the work piece surface; a driver moving the contact pin unit forward and backward along the surface of the work piece; and a joint coupling the contact pin unit and the driver to a measurement head holder of a coordinate measuring system. The surface roughness measuring unit further includes a contact detector that detects contact of the skid on the surface of the work piece.

Abstract: A method of placing a work piece on a measuring device in which a work piece is placed on a table of a measuring device is provided. The method includes: using a retainer capable of holding the work piece above the table and a lifting/lowering device lifting and lowering a top surface of the table; holding the work piece above the table with the retainer; lifting the top surface of the table with the lifting/lowering device to bring the top surface of the table into contact with a bottom surface of the work piece; and, after a load of the work piece is borne by the table, releasing the hold of the retainer on the work piece.
