ABSTRACT:
The improvement of a tape recorder mechanism which comprises a push-back angle plate located at the leading end of swivel arm, an intermediate gear installed on the swivel arm and engaged to the winding gear, a knockback slider installed between the operation lever and main deck, and a rewind slider installed on the secondary deck. The swivel arm is linked with a transmission mechanism by a split spring which provides means for the advancing and returning movement of both parts. When the tape winding operation is stopped, the overwinding of a short piece of tape during stop operation is avoided automatically by simply pressing down the stop operation lever. The first step of pressing down the stop operation lever to move the lever mechanism a small distance ahead, enables the push-back angle plate on the swivel arm and the knock-back slider, pushing the pinch roller bracket and swivel arm simultaneously, therefore the intermediate gear is disengaged from the driven gear and the pinch roller is separated from main guide shaft. Continue pressing down of the stop operation lever to further advance the displacement of the lever mechanism, the forward operation mode of magnetic head is released and the forward play mode is tripped out. The aforementioned process can stop motion simultaneously when the stop operation lever is depressed. Thus the overwinding of a short piece of tape can be avoided.
