Zusammenfassung:	PURPOSE:To attain a stable tape running by providing a friction material to keep a small gap against a guide roller. CONSTITUTION:A magnetic tape 15 is guided into a V-shaped groove 19' of a receptacle 19 under the state hooked with the guide roller 7 by the movement of a guide roller base 5. As a result, the tape 15 runs through the circumferential side of a head drum. When a sag is generated in the tape due to some disturbance of harmony or other, the tape is going to get over the outer circumference of a lower flange part of roller 7 but can not exceed the flange part of roller 7 for further movement as it is abutted to the friction material 22, and also a coefficient of friction of the friction material 22 is large, therefore, the tape is never slid and is prevented from detachment. By this procedure, the tape 15 is stably held and prevented from falling off from the drum 3, then the stable running is attained.
