Claims

[Scope of utility model registration request]

In a flexible parallel ruler in which a cursor side link and a head support link are connected via a parallel movement mechanism so that the head part and scale are moved up and down substantially parallel to the drawing board surface, the cursor side link and the head support link are connected. A support lever with one end serving as a swing fulcrum and the other end serving as a push-up part is provided between the scale and the support lever so that it can swing freely along the vertical direction of the scale, while a push-up spring member is provided between the swing fulcrum side and the support lever. The spring action angle of the push-up spring member with respect to the line connecting the swing fulcrum of the support lever and the force application point of the push-up spring member increases as the head portion and scale move upward relative to the drawing surface. Furthermore, on the push-up part of the support lever,
A head part support device for a universal parallel ruler, which is provided with an arm guide that interlocks the push-up part when the head part and the scale start moving upward.
