Counterbalancing apparatus for use in an optical instrument. |
摘要 |
<p>An apparatus for counterbalancing the weight of the movable member in a precision instrument includes a resilient member which is coupled, by way of a non-elastic member, over an eccentric surface of a rotatable member to the movable member. Rotation of the eccentric member causes the resilient member to deform an amount proportional to the eccentricity of the member and a nearly constant counterbalancing force may be applied to the movable member.</p> |
