An apparatus is arranged to draw out a tape wound around a pair of reels accommodated in a cassette, bring the tape into abutment with a rotary drum, and record or reproduce information on or from the tape. The apparatus includes a pair of reel mounts for enabling rotational force to be transmitted to the pair of reels, respectively, a rotational driving part for transmitting a rotational driving force to either one of the pair of reel mounts, a detecting part for detecting a rotation of the reel mount to which the rotational driving force is transmitted, and a decision part for determining that the cassette is not inserted in the apparatus, if the reel mount to which the rotational driving force is transmitted is rotating at a rotational speed greater than a predetermined rotational speed.
