ABSTRACT:
A medical stand apparatus includes a drive mechanism for moving a counterweight in a balancing direction and a balance-sensing mechanism for sensing balancing-state of a parallel link mechanism and for sending a signal to the drive mechanism. The balance-sensing mechanism is provided on a connection shaft on which arms of the parallel link mechanism intersect with each other. When the angle between the arms on the connection shaft is displaced due to upset of balance, a switch corresponding to the direction of angular displacement is pressed by the tip portion of a lock pin. As a result, the pressed switch sends a signal to the drive mechanism, whereby the counterweight is automatically moved in a balancing direction. Since balancing adjustment can be automatically performed in this manner, time required for the balancing-adjustment work is reduced, and a person unfamiliar with the balancing-adjustment work can readily carry out the work.
