Image Number 4 for United States Patent #6185103.
A removable, EMI-shielding hard disk drive module for a notebook computer is pivotally insertable into the computer through an opening in the computer's base plate. Connectors fixedly mounted on the module and computer, respectively, mate when the module is fully inserted. A pin on the module cooperates with a movable cam on the computer to automatically lock the module in position when it is fully inserted, and to positively but smoothly disengage the connectors when the lock is released for removal of the module. To facilitate removal, the cam may lightly hold the module, after the connectors are disengaged, in a position where the module is easy to grasp and remove.
