<p>PURPOSE:To select freely an operation with one operation button, by providing an operation lever for setting the play mode and an operation lever for setting the fast-forwarding/fast-rewinding mode and locking either of them through a lock member by the operation button. CONSTITUTION:A forward and backward movable operation button 3 is inserted to a prescribed hole part of a horizontally movable operation lever 2 for setting the fast-forwarding/fast-rewinding mode, and an operation lever 1 for setting the play mode is engaged with the tip, and a lock member which is engaged with either of operation levers 1 and 2 is provided. When the operation button 3 is depressed, the operation lever 1 is moved forward straight and is locked by the member 4 to operate a head attaching plate, thus setting the play mode. When the operation button 3 is moved in this state, the fast-forwarding/fast-rewinding mode in the play mode is set through the operation lever 2. When the button is picked and moved, the fast-forwarding/fast-rewinding mode in the non-play mode is set. Thus, five operations are selected with one operation button.</p> |
