PURPOSE:To take the shape so that the cassette case can not be contacted to the capstan shaft at all times, by providing the cassette case which can reduce the capstan diameter and the tape loading mechanism which loads the magnetic tape through the use of the cassette case. CONSTITUTION:The bottom half of a cassette consists of the 1st and 2nd halves 1a, 2a supporting the tape winding, and the 3rd half 3a latching the said both halves 1a, 2a with a pair of hooks 4, 4, and the shape of the ceiling half is symmetrical to the bottom plate surface by surface. Further, the tape loading device supports the 1st and 2nd two loading discs laminated with a plurality of steel balls 8 by the support rollers 14, 15, 16 arranged with three support poles 11, 12, 13 on the base, and both the discs 9, 10 are turned in reverse direction with the loading rollers 26, 27 in interlocking with the loading motor. With the constitution like this, the cassette case has the shape not in contact with the capstan shaft regardless of the change in the winding diameter of tape winding body. |
