TAPE TENSION ADJUSTMENT DEVICE OF TAPE RECORDER

PURPOSE: To perform accurate fine adjustment by attaching a slider so that it has an elastic force and moving the slider by the tension pin of a tension arm turned by the tension of a running tape. CONSTITUTION: A tension pole 47 of a tension arm 42 is rotatively moved with a tape 26 by an extent by which the back tension of the tape 26 is larger or smaller than a prescribed value, and a tension pin 44 is rotatively moved in an amplified state. Since the pin 44 is brought into contact with the contact projection of a slider 32, it is guided by a guide bar 32 of a holder 30 to transport the slider 32. Since the tension applied to a tension band 12 is changed then, it changes the value of the load generated at the time of rotation of a supply reel 10 to finely adjust the back tension of the tape 26 to a fixed value. Thus, the damage of the tape 26 is prevented and the tape is stably run.
