テープカセット筐体の一部に該テープカセット筐体内に
設けられた機構部材と交差しないような光路手段を設け
、該光路手段の両端を上記テープカセット筐体外面に夫
々露出するようにすると共にテープレコーダの上記光路
手段の両端に対応する部分に発光手段及び受光手段を設
ける様にし、該発光手段よりの光が上記光路手段中を通
過したことを上記受光手段により検知し、上記テープカ
セット筐体に光路手段が有するかどうかを検知する様に
したことを特徴とするテープカセットの認識機構。A part of the tape cassette housing is provided with an optical path means that does not intersect with a mechanical member provided inside the tape cassette housing, and both ends of the optical path means are exposed to the outer surface of the tape cassette housing, and the tape A light emitting means and a light receiving means are provided in portions corresponding to both ends of the optical path means of the recorder, and the light receiving means detects that the light from the light emitting means passes through the optical path means, and the tape cassette housing is detected by the light receiving means. A tape cassette recognition mechanism is characterized in that it detects whether or not an optical path means has an optical path.
