Abstract
A stand mechanism for medical optical equipment wherein the optical equipment is supported by a parallel linkage and the balance of weight with respect to all movement directions such as, for example, vertical, horizontal and pivotal directions of the parallel linkage is maintained. The optical equipment is disposed in a weight-balanced condition and therefore can be moved to any desired positon by means of small movement forces being exerted thereon and hence the movement operation can be carried out more exactly and more rapidly.
