<p>PURPOSE:To maintain the accuracy of a mechanical position of the magnetic tape winding outer peripheral surface upper and lower fixed drums and to enable a miniaturization by arranging a tape guide sharing a part of the outside space area of the outer peripheral surface of the lower fixed drum. CONSTITUTION:The part of a tape guide 78 is arranged at the outside space area between the drum fixing part 64b' of a drum connecting member 64 and the outer peripheral surface an annular lower drum 47. When a rotary drum is rotated, recording heads 43 and 43' and reproducing heads 44 and 44' are rotated in an arrow direction 40 and a magnetic tape 32 is wound along a tape guide 33, an erasing head, a tape guide 35, a rotary head device, tape guides 78 and 36', an audio control head 37 and a capstan 38. When the formation of a tape traveling path is completed, a capstan 38 is rotated, a tape 32 is traveled in an arrow direction 41. Thus, the mechanical accuracy is maintained without increasing the thickness of the fixed drum connecting member and the device is miniaturized.</p> |
