Abstract:
A cam projection sliding in a cam slot of an arm causes the arm to proceed to an arm when a shutter is in the closed position or the open position and to recede from the arm when the shutter is sliding between the open position and the closed position. A spring is thereby considerably displaced, providing a satisfactory operation of the shutter.

Claim (Index 4):
A shutter mechanism comprising:\n a base having a pair of base slots, a pivot-axle projection, a guide projection, and a cam projection; a shutter comprising a pair of shafts engaging with the pair of base slots and configured to slide between two positions located on the base in response to slide of the pair of shafts through the pair of base; a pair of arms, each arm having one end engaging with one of the pair of shafts and another end engaging with each other so as to be moveable in a transverse direction in which the arms move toward or away from each other; and a spring attracting the arms toward each other, wherein one arm of the pair of arms has a pivot-axle hole rotatably engaging with the pivot-axle projection and is configured to rotate around the pivot-axle projection in response to slide of the shutter, and the other arm of the pair of arms has a long engage hole rotatably and slidably engaging with the cam projection of the base and a curving cam slot slidably engaging with the cam projection, and is configured to move in the transverse direction while rotating around the guide projection in response to slide of the shutter to cause the other end to get close to the one arm when the shutter is in either of the two positions and get away from the one arm when the shutter slides between the two positions by slide of the cam projection in the cam slot in response to slide of the shutter.
