An external connecting electronic apparatus includes a case body, a connector and a cap plate. The connector and the cap plate are pivotally coupled on the case body in a movable manner. The connector has at least a hidden position in the case body for storing and a connecting position outside the case body. The cap plate has at least a masked position for covering the case body and an open position extending outwards. The cap plate corresponds to a free end of the connector. Thus when the cap plate is pushed, the connector may be moved at the same time.
