ABSTRACT:
A double-cassette-type magnetic recording-reproduction apparatus wherein a cam gear allows the second over-stroke lever to shift in advancing and retracting manners and, following these movements, a mode lever and the second head mount are allowed to move to the first through third positions. When the mode lever is located at the first position, the first over-stroke lever is shifted to an operable position and the second head mount is blocked by the second idler lever from its advancing movement. When the mode lever is located at the second position, the shift-blocking state of the second head mount is released, and the first over-stroke lever is not allowed to shift. When the mode lever is located at the third position, the first over-stroke lever and the second head mount are allowed to shift to the operable positions. This construction makes it possible to reduce the number of driving means and cut the cost of production.
