ンド検知装置。 A reel table that is rotatable around the axis of a reel shaft and has a reel engaging member that engages with the reel center hole of the cassette tape so that rotation can be transmitted; and a predetermined drive source that is coaxial with the reel table. and a slip gear that receives rotation transmission from the reel table and can rotate integrally with the reel table with a predetermined frictional force, and when a load exceeding this frictional force is applied to the reel table, the reel table and In a cassette tape reel drive mechanism configured to rotate relative to a slip gear, a disk rotatable with the reel table is provided coaxially with the reel table and the slip gear and at a position below the slip gear, A plurality of holes penetrating vertically through this disc are formed along its circumferential direction, and a reflective photo sensor is disposed at a lower position of this disc. A mechanical tape end detection device in a reel drive mechanism for a cassette tape, characterized in that one side is set to a color that absorbs light emitted from a light emitting element of a photo sensor, and the other side is set to a color that reflects this light.
