ABSTRACT:
A flat, multi-element writing instrument is described in which each writing element is attached to a glide element, a portion of which projects through a longitudinal slot in one face of the instrument's body for manual actuation. The longitudinal slots are located adjacent the side edges of a clip overlying one of the flat faces of the instrument's body. The glide elements include portions which underlie the clip and are received in respective channels formed in the undersurface of the clip, to interlockwith catches formed in these channels and hold their associated writing members in an extended, writing position. A cam within the writing instrument is positioned to have portions in the path of travel of each glide element so that, when one glide element is at least partially moved towards a writing position, the cam automatically pivots to move out of its path of travel and into the path of travel of another glide element to prevent its associated writing element from being extended.
