PROBLEM TO BE SOLVED: To provide a workpiece position control device which correctly controls workpiece position without requiring strict mounting thereof on a work table displacing apparatus, and to provide a workpiece position control method, an inclination measuring device, and a method for performing measuring operation by the inclination measuring device.;SOLUTION: According to the workpiece position control device, when the work table 11 assumes an initial position with no workpiece W mounted thereon, an origin (0, 0) is stored in a memory upon execution of 'a teaching mode'. When the work table 11 is inclined downward in an X positive direction from the initial position, a light-receiving position is shifted to a point Q deviated from an x axis in measuring coordinate systems, and a movement direction and a rotational deviation angle (-α) with respect to the x axis direction are stored in the memory. When the workpiece W is mounted on the work table 11 again and 'an inclination measuring mode' is executed, a positional signal P from a two-dimensional position detecting element 25 indicates a position (Lcosα, -Lsinα) which is then rotationally transformed to P' (L, 0).;COPYRIGHT: (C)2004,JPO
