<p>PURPOSE:To lessen the danger of head damage at the time of handling, such as assembling and transporting, by covering part of a cylinder with a cover. CONSTITUTION:This head cylinder includes an upper drum 1, a lower drum 2, a magnetic tape guide line 3, a magnetic head 4, the cover 5 fixed to this lower drum 2, a magnetic tape 6, a pass port 7 for this magnetic tape 6, inclined pins 8, 8' and a shaft 9. The magnetic head 4 is mounted at the upper drum 1 and rotates together with the upper drum 1 around the shaft 9. The magnetic tape 6 is made to travel at an adequate angle with the cylinder by a tape guide line 3 disposed on the lower drum 2 and inclined pins 8, 8'. The upper and lower drums 1, 2 are provided with the cover 5 having the tape passage port 7 having the width larger than the width of the magnetic tape 6 and, therefore, the tape 6 is pressed to the cylinder without hindrance by the cover 5. In addition, the danger of the damage of the magnetic head 4 at the time of handling is lessened.</p> |
