A rack master and a storage apparatus having the rack master are provided to allow an operator to adjust the angle of a reflector using a guide cover when the reflector is wrongly disposed, thereby easily correcting an error. A rack master loads cassettes and includes a vertically moving unit(150) and a sensor unit(200). The vertically moving unit vertically moves the cassettes. The sensor unit is attached to the vertically moving unit and guides a signal direction. A storage apparatus includes the rack master and a shelf. The shelf has a reflector. The reflector and the sensor unit are arranged opposite to each other. |
