PROBLEM TO BE SOLVED: To provide a position specification device that can secure a stable specification of a position with respect to a detection device sensing light incident via an incidence face from the light emitting object to detect a position of the light emitting object on the incidence face.SOLUTION: A position specification device comprises a plurality of light elements 21, 21, ..., and 21 different in an irradiation angle of light with respect to an incidence face. On the basis of a pose of an own device, any of the light emitting elements 21 in which incidence upon the incidence face is properly performed is selected, and a specification of a position is performed by use of light from the selected light emitting object.SELECTED DRAWING: Figure 3 |
