Abstract
A lock mechanism for the clutch of a reel base of a tape recorder, which comprises a fast forward gear to be simultaneously engageable with or disengageable from a pair of upper and lower reel gears of the reel base equipped with a clutch function in accordance with the action of a head mount plate movable together with the reel base in such a manner that the fast forward gear is disengaged from the two reel gears of the reel base according to the forward movement of the head mount plate in a recording/reproducing mode, thus enabling the clutch function of the reel base, and the fast forward gear is simultaneously engaged with the two reel gears of the reel base according to the backward movement of the head mount plate in a fast forward mode or rewinding mode, thus locking the clutch function to disable the clutch.
