<p>PURPOSE:To keep stable lock release state with a small force required for lock release by using a wedge provided to a pressing member so as to turn a lock member thereby releasing the lock. CONSTITUTION:A press rod 2 is loaded to an insertion hole 3 with loading of a reel cassette, a pressing part 14A of a pressing member 14 is depressed, the member 14 is turned around a fulcrum shaft 15 to allow a wedge 14B to open press arms 16B, 17B of the lock members 16, 17 horizontally. Thus, the lock parts 16, 17 are turned clockwise and counter clockwise respectively to release the lock of the reel 10 thereby maintaining the release state. Through the constitution of employing the wedge without using a press rod with a high stiffness, the lock release of the reel is attained by a small force to maintain the release state stably.</p> |
