PURPOSE:To suppress the increase of tension of a tape, and to make it run stably, by providing an elastic material on the outside circumference of a rotary roller which is made to press-contact with a composite head for executing full width erasion, and erasion and recording of a voice, to the upper flow side of a head cylinder. CONSTITUTION:On the upper flow side of a rotary cylinder provided with a video head, a composite head 15 for executing full width erasion, and erasion and recording of a voice is provided. A rotary roller 17 which is made to press- contact with the composite head 15 is fitted to the end part of an arm 20 so as to be freely rotatable, and sends a tape 1 in the direction as indicated with an arrow by pinch-holding it with the head 15. The outside circumferential surfaces of the rotary roller 17 is covered with an elastic material. The arm 20 is axially supported 21, pushes the roller 17 by a spring 22 in the direction of the head 15, and executes positioning by a stopper 23 and a screw 24. A video track controlling head which is not shown in the figure is provided on the lower flow side of the rotary cylinder. In this way, a load put on the tape is widely dispersed, strong tension is not exerted on the tape, and it becomes possible to make the tape run stably. |
