Abstract
In a mode changeover apparatus for a magnetic recorder/player having a plurality of push-buttons for directing changeover of tape drive modes, a simple and compact mechanism for effecting mode changeover including an eccentric idler, a restraining mechanism, a locking mechanism, an engaging mechanism a locking member, a lever, a releasing mechanism and a holding mechanism. The idler is mounted on a slidable support, and can be rotated through a capstan wheel which is driven by a motor. The support carries a magnetic head, and can be moved by the rotation of the idler. The restraining mechanism restrains the support to a reproduction position. The support is moved to a non-reproduction position through the engaging mechanism and is locked there by the locking mechanism. The releasing mechanism releases the support from the non-reproduction locking. The idler is locked to a state that its smallest radius portion confronts the capstan wheel by the locking member. A small gap can be left between this smallest radius portion and the capstan wheel by the holding mechanism. The idler can be brought into rotating relationship with the capstan wheel by the lever which temporarily releases l…
