出する手段とを具備してなることを特徴とするVTRに
おけるテープ保護装置。[Claims for Utility Model Registration] Tape detection sensors are installed on the outlet and inlet sides of the tape from the cassette, and under normal conditions, the tape detection sensor detects the end of tape winding and then activates the loading mechanism to unload the tape. A tape protection device for a loading VTR, which includes a reversal signal sending means for reversing a supply reel motor in the winding direction when only an inlet tape detection sensor detects no tape during operation; 1. A tape protection device for a VTR, comprising means for sending an unloading signal to the loading mechanism after a tape detection sensor on the exit side detects no tape after reversal.
