发明名称 Drive unit structure for keyboard assemblies
摘要 A drive unit structure for a keyboard assembly is provided, which comprises a driven member having a flat sliding surface and pivotable about a fulcrum thereof, and an actuator disposed for sliding contact with the flat sliding surface of the driven member to pivotally drive the driven member. The fulcrum of the driven member lies in a plane including the flat sliding surface of the driven member. As a result, the operations of the actuator and driven member can be stable, to thereby enhance the accuracy of transmission of the operation of the actuator to the driven member.
