    摘要: A mechanical pencil unit of the pushbutton-action type and a ballpoint pen unit are housed in a common holder having top and bottom sections which are rotatable in oppposite directions relative to each other. Mounted within the holder and substantially secured to its bottom section only is a cradle which supports and constrains the two writing units for independent longitudinal motion with respect to the holder. The writing units are spring-biased into sliding engagement with an overhanging, downward-facing cam ledge on the inside surface of the holder top section, such that the writing units are selectively moved from a retracted to a writing position upon manual rotation of the holder top section in either direction relative to its bottom section. Upon movement of the mechanical pencil unit to the writing position, an offset pusher finger extending downwardly from a pushbutton on the holder is moved into alignment with the pencil unit for actuating and making the same ready for writing or marking.
