Claims

[Scope of utility model registration request]

a first electromagnetic means for moving the head board between a playing position and a non-playing position; a pinch roller selection member pivotally supported by the head board and selectively pressing the pinch roller against the capstan when moved to the playing position; a control member that moves between two linear positions and selectively transmits driving force to the first and second reel gears by moving to the two positions; and a control member that moves the control member to a second linear position. and a third electromagnetic means for releasing the first electromagnetic means in a high-speed drive mode such as fast forwarding or rewinding, thereby holding the head board between a non-playing position and a playing position. 1. A magnetic recording and reproducing device characterized by comprising:
