Abstract: An ejecting mechanism provides an ejecting executing portion driven by an ejecting driving portion for pushing a secondary machine out of a primary machine and for separating a secondary connector and a primary connector connected to each other. It allows the secondary machine to be ejected out of the primary machine automatically and prevents damage of the secondary connector and the primary connector caused by applying an external pulling force on the secondary machine directly. Furthermore, when a first external force overcomes a resilient driving force to push the secondary machine into a slot, the ejecting executing portion contacting with the secondary machine swings toward a rear end of a connecting surface of the primary connector. Additionally, an ejecting locking portion moving with the swing of the ejecting executing portion can be locked by a locking executing portion, such that the automatic ejection of the secondary machine is restrained.
