In a magnetic recording/reproducing apparatus having a plurality of push-buttons for directing changeover of tape drive modes, a simple and compact mechanism for effecting mode changeover including an idler, a reciprocating member, sliding actuating bars and an alternative-selection mechanism, all operated by the motive force from a motor-driven capstan. The idler is mounted for movement into and out of contact with a wheel mounted for rotation with the capstan and the reciprocating member moves responsive to the movement of the idler. The idler can be carried to a position spaced from the capstan wheel by the movement of the reciprocating member. Actuating bars, one associated with each push-button, are engaged and disengaged with the reciprocating member by an alternative selection mechanism. By manually depressing one of the push-buttons, the idler is brought into contact with the capstan wheel, and the corresponding actuating bar is brought into engagement with the reciprocating member, thus effecting the selected mode changeover.
