ABSTRACT:
A modular keyboard (12) for a tablet personal computer (10) provides a cover on an outer side (16) for covering the base unit (14) screen (18) and an inner side (46). A key array (44) for key-based data entry into the base unit (14) mounts integrally to the inner side (46). A back support (48) supports the base unit (14) in a raised position relative to the key array (44) and presents the base unit (14) for monitoring data entry from the key array (44). The back support (48) is retractable to a recess (90) that is substantially parallel to the inner side (46). Side support arms (54) cooperate with the back support (48) for supporting the base unit (14) and holding the base unit (14) securely relative to the back support (48). The side support arms (54) are retractable to a recessed position substantially parallel to the inner side (46). A bus connector (78) connects and communicates key-based data between the key array (44) and the base unit (14).
