Abstract: The locking and ejecting apparatus includes a latching mechanism, an ejection mechanism, a first string and a second string. The latching mechanism is for locking the module device in a locked position or unlocking the module device from the locked position. The ejection mechanism is for ejecting the module device on disengagement of the latching mechanism from the locked position. During the unlocking and ejecting operations, the second button is pulled right after the first button is pressed. After the module device is released from the locked position and ejected out of the internal bay, the first spring positioned to generate a first force restores the latching mechanism and the second spring positioned to generate a second force restores the ejection mechanism.
