Abstract: There is provided an optical connector device which prevents leakage of light until right before connectors are connected to each other and is small-sized by a reduction in space for housing shutters. The optical connector device is an optical connector device comprising a first optical connector and a second optical connector. When shutters for shutting out light from the optical connectors are collided with each other, the shutters move to positions where they do not shut out the light. Therefore, the first optical connector and the second optical connector are connected to each other. After moving, the shutter of the first optical connector and the shutter of the second optical connector are inserted into the second optical connector while remaining contacting each other.

In the card connector, the ejection unit includes an inclining member for inclining downwardly a portion of the ejection unit to be pulled out toward the direction that the card is pulled out when the spring member urges the ejection unit in the direction that the card is pulled out.

Abstract: The latching metallic piece (12) has a lever-like arm (20) that extends in the direction of receiving the flat-type cable C. The lever-like arm (20) has a latching claw (20A) at one end, a fulcrum section (22) at the middle point, and an extending section at the other end. A pressuring member (14) has a restricting section that does not contact with the extending section (20B) of the latching metallic piece (12) at the open position, and that prevents the displacement of the extending section at the closed position. When the pressuring member is at the open position, the lever-like arm (20) is in the state that it can be freely displaced so as to allow insertion/removal of the flat-type cable. When the pressuring member is at the closed position, the displacement of the lever-like arm relative to the latching section in the direction that increases the latching of the latching claw (20A) is prevented, and the displacement of the lever-like arm in the direction that reduces the latching is prevented.
