Abstract

PURPOSE: To permit the continuous variation of reduction and expansion rates by totatably connecting a slider attached to a link connecting sliders laid to two parallel links facing each other to a slider attached to a link positioned on a diagonal line.
CONSTITUTION: When a link 5 is moved while keeping it in parallel with links 3 and 4 in order to determine the reduction-expansion ratio, a slider 12 moves on a link 6 and at the same time a slider 13 moves on the link 5. Afterwards, a pin 9 is moved in the radial direction around a pin 7 as the center, the link 6 slides inside the sliders 11 and 12. Furthermore, the link 5 can continuously move along the links 1 and 2 through the sliders 14 and 15. Thus, the reduction or expansion ratio of pantagraph can be continuously changed. The link 6 may be made of a thin steel plate and its one end may be so designed that it can be housed.
