Abstract
Abstract Disclosed is a hand held computer having a housing. The housing has a first side and a second side wherein the second side is opposite the first side. A display and a processor are included in the housing. There is an opening in the first side of the housing for receiving a memory card. A connector is mounted within the housing for connecting the memory card to the processor. An ejector mechanism is operable from outside the housing from the second side to eject the memory card from the connector. The ejector mechanism has a bar that spreads the ejection force to both corners of the card nearest the connector so as to provide balanced ejection force to eject the card without damage to the connector contacts. The bar is moved by a button which is held captive in the second side of the housing. The button transmits the force provided by a user's finger to the bar.
