<p>PURPOSE:To record signals on plural magnetic tapes simultaneously by providing at least one kind of rotating members such as rotary head parts and capstans in running mechanisms for plural tapes on the same shaft, and driving the shaft by one common motor. CONSTITUTION:The rotary head parts of plural tape running mechanism provided in the breadthwise direction of magnetic tapes are coupled with one common motor and driven in common. Namely, plural substrates 30, 30- are provided vertically at specific intervals, and lower cylinders 40a of drums 40 for the rotary heads are fixed onto the respective substrates 30, 30- slantingly to the respective substrates by using fitting screws 40b, 40b-. An upper cylinder 40c having the same diameter with a lower cylinder 40a is provided on the top surface of the lower cylinder and a rotary head 40d is fixed to the upper cylinder 40c between the reverse surface of the upper cylinder 40c and the top surface of the upper cylinder 40a so that the rotary head 40d rotates in one body.</p> |
