Provided is a teaching unit which is capable of accurately determining the position of an overhead moving device relative to a reference position of a transfer section regardless of tilting of the moving device with respect to the reference plane of the transfer section. This teaching unit is mounted on either an overhead moving device (10) or a load port (3) from which an object to be conveyed is transferred by the overhead moving device (10). The teaching unit is provided with: distance sensors (23X1, 23Y1, 23Y2) for detecting the position of the overhead moving device (10) relative to a reference position of the load port (3) when said sensors are separated from the other of the overhead moving device (10) or the load port (3); and distance sensors (23Z1, 23Z2, 23Z3) for detecting tilting of the distance sensors (23X1, 23Y1, 23Y2) with respect to the reference plane of the load port (3) when said sensors are separated from the other of the overhead moving device (10) or the load port (3). |
