ALL-AUTOMATIC STOPPING MECHANISM FOR A RECORDER

摘要

A rotatable sensing member is mounted on the end surface of the tape reel. The move pin of the sensing member can actuate a swing lever to swing towards one direction or to maintain a tendency towards this direction. The driving end of the swing lever may abut against the eccentric circumference of end surface of the fly wheel. There is a protruding stopper at a side of the eccentric circumference. One end of the swing lever can sense whether the tape reel is rotating or not. The other end can pass through inside or outside of the stopper according to the sensing result so as to operate the recorder without interference or to generate a larger movement to pull and move the locking lever and to stop operation of the recorder. As compared with prior art, according to abovementioned mechanism, it is possible to reduce number of elements and to raise assembly accuracy and to reduce transmission noise.
