<p>PURPOSE:To eliminate the delay of shift time by providing moving bases or moving base operating member with sensors which detect the relative displacement between the both and discriminating whether the moving bases move from the position of a large-sized or small sized tape cassette device. CONSTITUTION:The moving bases 3 and 4 or moving base operating member 7 is provided with a sensor 71 which detects the repellence when the moving bases 3 and 4 move from the large-sized tape cassette device position and a limiter spring 17 is compressed and a sensor 7 which detects the repellence when the moving bases 3 and 4 move from the small-sized tape cassette loading position and the limiter spring 16 is compressed. Namely, when the moving bases 3 and 4 move from the large-sized tape cassette loading position side to an intermediate-size tape cassette loading position, one sensor 71 detects that and when the moving bases move from the small-sized tape cassette loading position side, the other sensor 72 detects that. Consequently, the delay of the shift time can be prevented from being caused.</p> |
