Abstract: A cassette loading device for a cassette recording apparatus includes a cylindrical cassette magazine having a plurality of radially directed slots, each adapted to contain a tape cassette, and narrow slits along the circumferential periphery thereof for receiving paper slips, each slip having information thereon concerning the recording of a tape cassette in a respective slot; a drive device for intermittently rotating the cassette magazine so that the radially directed slots are successively disposed at a cassette laoding position; a detecting apparatus for detecting the presence of a paper slip in the slit which is retarded by one step with respect to the slit corresponding to the radially directed slot at the cassette loading position and for generating an output signal in response thereto; and a circuit responsive to the output signal for preventing the intermittent rotation of the cassette magazine by the drive device.
