That is, when the frame 29 of the first cassette mounting section 16 is lowered and the frame 29 of the second cassette mounting section 17 is rising, the guide section 30 of the first cassette mounting section 16 is on the transfer line. Therefore, the microcassette 3 taken out from the cassette holder 1 passes through the fixed guide 32 , the guide section 30 of the first cassette mounting section 16 , and the fixed guide 33 to the cassette holder 3 of the second cassette mounting section 17 .
A cassette 3 is transferred into the container 1. Alternatively, the cassette 3 held in the cassette holder 31 of the second cassette mounting section 17 is returned to the cassette holder 1 via a path opposite to the above-mentioned path.

Therefore, two cassette mounting parts are provided in the transporting direction of the transporting means 18 for the cassette 3, and the movement of the cassette 3 between these two cassette mounting parts 16, 17 and the cassette holder 1 is performed by a single transporting means. Even if this is done, it is possible to transfer the cassette 3 to the second cassette mounting section 17 or to take it out from the second cassette mounting section 17 regardless of whether or not the first cassette mounting section 16 is used. Become. Therefore, in this cassette changer, two cassette mounting parts 16, 1 are randomly installed.
Cassette 3 can be attached to 7. Therefore, according to the cassette changer of this embodiment, there is only one transfer means, which simplifies the structure, and the next cassette 3 can be placed in advance in either the cassette mounting section 16 or 1.
By attaching the cassette to cassette 7, it is possible to eliminate the time loss of replacing the cassette.

As described above, in the present invention, a guide section is provided at least in the cassette mounting section other than the cassette mounting section located farthest from the cassette holder, and the cassette is held in the cassette holder by the forward movement of the cassette holder. When a tape cassette is installed in a predetermined cassette mounting section, the guide section constitutes a guide means for guiding the tape cassette to the cassette holder of another cassette mounting section. A single transfer means for transferring cassettes in the array direction allows cassettes to be transferred randomly to a plurality of cassette mounting locations.
