发明名称 TAPE TENSION REGULATOR OF TAPE PLAYER
摘要 <p>PURPOSE:To stabilize writing and reading by a method wherein, when a supply side reel table is braked to regulate a tension applied to a magnetic tape in accordance with the result of detection of the tension, the tension is so regulated as to be a predetermined tape tension corresponding to the thickness of the magnetic tape wound in the reel. CONSTITUTION:A tension applied to a magnetic tape is detected by a tension detecting part 20 and, in accordance with the detected result, a tension regulating part 21 brakes the rotation of a supply side reel table to regulate the tension of the magnetic tape. At that time, the thickness of the magnetic tape wound in a tape cassette is detected by a detecting means and a tape tension corresponding to the detected thickness is predetermined by a tape tension predetermining means. A tape tension regulating means regulates the tension of the magnetic tape with the tension regulating part 21 so as to be the predetermined tape tension. With this constitution, an optimum tape tension can be obtained and stable reading and writing of magnetic information can be realized.</p>
