<p>PURPOSE:To minaturize a mechanism related to a tape loading motion, by oscillating an arm member which supports a loading member while a ring-shaped matter is turning so that the loading member moves along its moving path. CONSTITUTION:A loading motor 74 is actuated with a recording or reproducing operation, and a ring 60 turns toward an arrow F. Then a support stage 20 is pulled by an arm member 64 while two projections 20a and 20b on the lower side of the stage 20 are guided by a guide groove 22. In this case, the member 64 moves while oscillating toward an arrow C so as to compensate an error of the ring diameter direction of a pin 63 of the groove 22 to the turning locus. The stage 20 moves with oscillation toward an arrow D in response to the extending direction of the groove 22. As a result, the diameter of the ring-shaped matter can be reduced by an amount equivalent to the length of the member 64.</p> |
