An apparatus, for detecting the starting or ending portion of a tape, has a detector for detecting the starting portion or the ending portion of the tape wound on a take-up reel and a supply reel of a cassette. The apparatus includes a first guide installed on at least one side adjacent to the tape inlet/outlet opening of the cassette to be loaded, and which is in contact with a recording surface of the tape. A second guide is fixed so as to be electrically insulated from the first guide, and is in contact with a recording surface of the tape. A voltage applying circuit is provided for applying a predetermined voltage level across the first and second guides. The starting portion or the ending portion of the tape is detected depending on the presence or absence of electrical current between the first and second guides.
