<p>PURPOSE:To prevent damage of a tape without causing tension in the upper and lower edges of the tape by providing a slant controlling mechanism that tilts a subloading device from vertical state gradually adapting to change of twisting when a tape is wound spirally bit by bit on the peripheral face of a rotary head drum. CONSTITUTION:At the time of main loading, a main loading device 9 comes into contact with a tape 4 is lowered in the direction of arrow mark (c) while being tilted gradually from vertical state to the position of going movement shown by solid lines. Accordingly, twists having upward slanting angle (climbing angle) is generated in the tape 4 between the main loading device 9 and sub- loading device 7. Accordingly, the sub-loading device 7 is made to follow the inclination of the main loading device 9 by an inclination controlling mechanism at the position of going movement shown by solid lines, and tilted gradually from vertical state in the direction of the arrow mark f.</p> |
