An automatic transfer apparatus comprising:
- a mounting unit for holding a cassette in which a plurality of substrates are received;
- a moving unit below the mounting unit for moving the mounting unit;
- and
- a sensing member mounted in the moving unit for sensing an obstacle in a path of the transfer apparatus,
- wherein the sensing member includes
- two tape sensors spaced apart from each other by an interval;
- and
- a sensing bar with one end coupled to one of the two tape sensors and the other end of the sensing bar protruding downwardly from a lower portion of the moving unit.
An automatic transfer apparatus comprising:
- a mounting unit for holding a cassette in which a plurality of substrates are received;
- a moving unit below the mounting unit for moving the mounting unit;
