<p>PURPOSE:To improve operability by discriminating an adaptor from a first cassette from the logic of another contact when one logic of a second contact is set at prescribed logic, and discriminating the placing state of the adaptor. CONSTITUTION:A first contact 32 consisting of plural contacts K1, K2 are formed at the right and left side planes of the adaptor 30, and also, the second contact 31 consisting of plural contacts Y1-Y5 are arranged on the middle way of a route where the adaptor 30 is drawn in and out so as to come in contact with the first contact 32 on the side plane on one side of the adaptor 30, and the discrimination of the adaptor 30 from the first cassette or the placing state of the adaptor 30 can be discriminated by detecting the logic of either one contact of the second contacts Y1-Y5, for example, the logical of another contact Y2 when that of the contact Y1 is set at logical 1 or 0. Therefore, it is possible to stop the adaptor 30 at a prescribed position in the middle way of moving when no second cassette is housed, and to eject the adaptor 30 when the adaptor is not placed correctly, which allows the second cassette to be surely loaded. In such a way, the operability can be improved.</p> |
