Abstract
A recording and/or reproducing apparatus using a tape-cassette includes a cassette holder for holding the tape-cassette, an operating mechanism for moving the cassette holder from an operative, or lowered, position to an eject, or raised, position, a first detecting device for detecting whether power is being applied to the apparatus, and a second detecting device for detecting whether the cassette holder contains a tape cassette. In the recording and/or reproducing apparatus, when the power switch is turned on while the cassette holder is in its operative position, and there is no tape-cassette in the cassette holder, the cassette holder is automatically raised to the eject position.
