SOLUTION: In this auro-changer device, the medium 5 is taken out from a drive 3 and returned to a magazine 2 by the transportation unit 4 when the medium is exchanged, then a new medium is taken out from the magazine and set to the drive 3. By the transportation unit 4, the medium 5 fetched from the magazine 2 or the drive 3 is moved by rollers 4b and fetched to a specified position in the transportation unit 4 and transported to the drive 3 or the magazine 2. When the medium 5 is fetched inside the transportation unit 4, the medium 5 is moved by driving the rollers 4b by the number of specific times till the existence of the medium 5 is detected by both of sensors S1, S2, then the medium is positioned. Thus, the medium in the transportation unit can be accurately positioned.</p> |
