<p>PURPOSE:To simplify a quick traversing and rewinding mechanism by providing two fitting holes to a quick traversing lever and a rewinding lever respectively as well as a plate spring having a playe end part projected downward above those fitting holes and fitting the play end part to the fitting hole to lock the lever. CONSTITUTION:When levers 13 and 14 are not pushed, play end parts 261a and 262a of a plate spring 259 are fitted to fitting holes 250 and 252 via through holes 257 and 258. When a lever 18 is pushed in a quick traversing mode, a hang-down part 254 presses a pressure surface 263 of a lock lever 190. Thus the lever 190 is displaced. When the quick traversing lever 13 is pushed completely, the parts 261a and 262a of the spring 259 are fitted to the fitting holes 251 and 253 via the holes 257 and 258 and locked. These parts 261a and 262a are also locked in the same way with push of the rewinding lever 14 in a rewinding mode.</p> |
