Incrementally moved cylindrical lens display system for toy

摘要

A toy computer includes a keyboard housing and a monitor housing pivotally secured by a hinge coupler. A depressible keyboard unit is pivotally supported by the keyboard housing and is coupled to a movable slider within the interior of the keyboard housing. A return spring is coupled to the slider and is operative to pivot the slider such that a ratchet engaging tooth is raised to its engagement position in the absence of a keyboard unit stroke. An endless belt display utilizes a cylindrical lens element array together with a segmented image formed on the endless belt to provide apparent motion of the image as the endless belt is moved. A ratchet coupling system is coupled between the slider and the movable belt to provide incremental belt motions in response to each keyboard stroke.
