Personal digital assistant assembly

A personal digital assistant assembly comprising:

• a base module having front and rear ends, and an operating surface;
• a pivot unit provided on said operating surface of said base module adjacent to said rear end and having a pivot axle transverse to said operating surface of said base module;
• a coupling block disposed on said operating surface of said base module and connected pivotally to said pivot unit such that said coupling block is rotatable about said pivot axle;
• a personal digital assistant module having a connecting end;
• a user input device provided on one of said base module and said personal digital assistant module;
• a liquid crystal module provided on the other one of said base module and said personal digital assistant module;
• and
• an elongated hinge unit defining a longitudinal axis parallel to said operating surface of said base module and transverse to said pivot axle of said pivot unit, said hinge unit being disposed on said coupling block and interconnecting pivotally said connecting end of said personal digital assistant module and said coupling block such that said personal digital assistant module is rotatable about the longitudinal axis and is movable to a desired angular position relative to said coupling block;
• said coupling block being operable so as to move between an expanded position, where said coupling block is moved away from said front end of said base module such that said personal digital assistant module uncovers said operating surface of said base module, and a closed position, where said coupling block is moved toward said front end of said base module such that said personal digital assistant module can be rotated about the longitudinal axis so as to be superimposed on said operating surface of said base module.
