Abstract
A computer is provided with a pair of internal PCMCIA card connection chambers opening outwardly through a pair of housing side wall slots through which PCMCIA cards may be inserted into and withdrawn from the chambers. To facilitate the disconnection and withdrawal of the inserted cards each chamber is provided with a mechanically leveraged card ejector mechanism positioned within a thin space between the facing sides of the inserted card and a housing wall portion of the chamber, and disposed essentially entirely within the peripheral footprint of the inserted card. Each ejector mechanism includes a manually operable actuating plate slidably disposed on the outer side of the computer housing, a card receiving/ejection plate overlying the actuating plate within the housing, and a lever plate sandwiched between the actuating plate and receiving/ejection plate and pivotally connected to the housing. As a PCMCIA card is inserted into its chamber it engages and inwardly drives the receiving/ejection plate which in turn inwardly pivots the lever plate causing it to inwardly drive the actuating plate. The pivotally mounted lever plate is connected to the actuating plate and receiving/ej…
