る自在平行定規における定規の平衡装置。 A vertical shaft 22 is rotatably supported on a head board 18 that is supported so as to be movable in parallel on the drawing board.
A ruler mounting plate 28 is fixed to the lower part of the vertical shaft 22.
In the device in which the handle 24 is fixed to the upper part of the
An eccentric cam 22 is fixed to the vertical shaft 22, a lever 34 is rotatably supported on the head board 18, and one end of the lever 34 is supported on the head board 18 at a portion eccentric to the center of rotation. coil spring 4
The other end of the coil spring 42 is connected such that one of the levers 34 comes into elastic contact with the outer peripheral surface of the eccentric cam 22 via a rotating body 48 due to the elasticity of the coil spring 42, and the lever of the coil spring 42 34. A ruler balancing device for a universal parallel ruler, characterized in that a connecting portion to the lever 34 can be moved and adjusted in a direction in which the amount of eccentricity with respect to the rotation center of the lever 34 changes.
