By this means, after the unlock operation member 16 is operated to move to the release position, the unlock operation member 16 is automatically returned to an original standby position only by releasing a hand from the unlock operation member 16. Thus, a new signal transmission medium can be inserted immediately without conventional operation for returning the unlock operation member or the like. |
