An escaping slot is provided on the bottom of the case nearby the rear portion leaving a slight space therefrom. The escaping slot is disposed along an erroneous insertion direction of the cassette for allowing the erroneous insertion of the cassette, with the rear portion being forward, into the holder by causing the detecting member to be inserted into the escaping slot after a wall of the rear portion overrides the detecting member with the further erroneous insertion of the tape cassette into the holder.
