Abstract

A handheld computer keyboard system for use in conjunction with small computerized apparatus such as Personal Digital Assistants (PDAs) features a keyboard, a cover, and an I/O connector to allow a computerized apparatus to be connected to the keyboard. The system also features a retractable stabilizing leg for greater stability when the system is set on a flat surface. The system allows a user to input text and data into a device such as a PDA, which typically must be done with a stylus, with a more convenient keyboard. The cover for the system closes to protect the keyboard and provides a support easel for the PDA when the system is in use.
