<p>PURPOSE:To directly connect a loading/unloading function and a mode generating function so as to interlock and operate them and to considerably reduce parts by elastically interlocking a loading ring and a tape pulling member by means of a pressure link to which a pressure spring is provided. CONSTITUTION:The position of a link shaft 11 when the loading ring 2 turns and a connection shaft 17 moves to nearly the center of the oblong hole 13 of the pressure link 12 is set to B, and the position of the link shaft 11 when the loading ring 2 turns and the connection shaft 17 moves to the end of the oblong hole 13 is set to C. After the tape pulling member 14 is abutted on a catcher 35 and a shift is locked, the pressure spring 18 extends due to the turn of the loading ring 2, and the tape pulling member 14 is brought into contact with pressure by the catcher 35 through a vertical post 15 and is positioned. For generating respective modes, the form of a Geneva cam 20 and the positions of pins 23 and 30 are set in such a way that a system goes to a rewind mode when the link shaft 11 is in the position B, and a reproducing mode when in the position C, for example.</p> |
