終端検出装置。 A light emitting part that irradiates a light beam onto the surface of a magnetic tape having a light-transmitting leader tape connected to both ends thereof, a member that reflects the transmitted light of the leader tape, a light receiving part that detects the reflected light, and a light emitting part and a light receiving part. In the optical actuator, a light emitting element and a plurality of light receiving elements are arranged side by side on the left and right sides on a substrate in the optical actuator, and a barrier is provided between the light emitting element and the light receiving element to prevent light from passing through. A tape end detection device characterized by an optical actuator having a spectral surface that divides the detection light beam from the light emitting element into left and right directions and makes the detection light beam from the reflection member enter the light receiving element.
