An apparatus and method for facilitating a synchronous display of a time-based media object with a remote device is provided. When a clutch member is pushed up, a rotating cam member, which is screwed together with the clutch member, rotates toward one side, and the reel locking member moves to a releasing position by a positive motion cam structured by a cam projection and a cam groove. Displacing means are provided to produce a gap between the object beam and the reference beam. The user applies the extraction pattern to the codebook and retrieves the symbols found at the selected positions, and submits these to the authenticating party.
