<P>PROBLEM TO BE SOLVED: To provide a detector that is excellent in detection accuracy and resolution and is capable of attaining size reduction, at low cost. <P>SOLUTION: A detector, which detects a thickness of an object or a traveling amount in a constant direction based on a datum face, includes a lever portion 1, one end of which is supported by a rotating shaft 3 and the other end of which has the datum face or a curved surface capable of abutting on an object and which oscillates with the abutment of the object, and a displacement transmission portion 2 which is supported by the rotating shaft 3 and is displaceable with the oscillation of the lever portion 1. The curved surface is machined to abut on the object at a point which substantially meets on one straight line V orthogonal to the datum face during the oscillation with the abutment of the object in an estimated range. <P>COPYRIGHT: (C)2011,JPO&INPIT |
