。In a tape end detection device that performs tape end processing by detecting a tape position using a light emitting means and a light receiving means provided near a tape running path of a tape recorder, a DC signal obtained from the light receiving means is passed through a switching means. After the AC signal is amplified by an amplification means, it is passed through a detection section and returned to a DC signal, and the value of the DC output or a change in the DC output is detected to perform tape end processing. Features a tape end detection device.
