<p>PURPOSE:To rotate a rotary drum at a stationary speed even under the state of half loading and to enable a quick shift to a recording/reproducing operation by preventing a magnetic tape from coming into contact with the rotary drum in using a standby post at the time of half loading. CONSTITUTION:The device is providing with the standby post 21 for abutting the magnetic tape 2 and preventing the magnetic tape 2 from coming into con tact with the rotary drum 3 at the time of the half loading state when the magnetic tape 2 is drawn out of a tape cassette 4. That is, the standby post 21 in a columnar shape is fitted on a loading ring 1 at a prescribed inclination, keeping a constant distance from a rotative post 5 to be disposed in a position outside the magnetic tape 2 in the direction of an arrow A. Then, under the half loading state, the standby post 21 is abutted against the magnetic tape 2 without twisting it, and the magnetic tape 2 is formed in its course where it is never brought into contact with the rotary drum 3. By this method, even when the rotary drum is under the stationary high-rotating state, the standby under the half loading state is feasible, thus performing the quick shift to the recording/reproducing operation.</p> |
