Abstract
A mode-change mechanism for a tape recording and/or reproducing apparatus of the auto reverse type requires only one partially toothless gear with at least four, toothless peripheral portions in order to change modes of operation of the apparatus. The gear with the partially toothless peripheral portions is rotated only in one direction, and rotates in turn from each locked position to its next locked position in selecting the various modes of operation, so that a stop mode, a forward reproducing or recording mode, a reverse reproducing or recording mode, a fast forward mode, and a rewind mode are selectively obtained.
