Abstract
A first sensor is disposed in such a way that optical axes of a light emitting element and a light receiving element thereof are parallel to a left-right direction. A second sensor is disposed in such a way that optical axes of a light emitting element and a light receiving element thereof are parallel to a front-rear direction. When a position of a wafer to be loaded on a loading portion is taught, a position of the loading portion or a teaching jig to be loaded on the loading portion in the front-rear direction is detected by the first sensor by moving a hand in the front-rear direction by a moving mechanism, and a position of the loading portion or the teaching jig in the left-right direction is detected by the second sensor by moving the hand in the left-right direction by the moving mechanism.
