<p>PURPOSE:To enable recording and reproducing of signals to and from a thin magnetic tape to be conducted with high accuracy by making the magnetic tape to travel stably. CONSTITUTION:A master cam gear 258 is rotated by a gear when a loading motor 235 rotates. A loading rack 315 is slide rightward by the rotation of the master cam gear 258. A tape leading out post 228 is rotated by the sliding force of the loading rack 315, by which an Su pole base 221 and a Tu pole base 222 are moved in a loading direction and a tension post 233' is rotated. The magnetic tape is thereby wound around the drum of a rotary magnetic head.</p> |
