Abstract

See full text

An automatic balancing structure of a medical balancing stand includes an elastic member arranged in each clearance C. In a normal state, a lever and a turn plate turn together through the elastic members, to follow a rotative movement of a lateral arm. When an imbalance occurs on the lateral arm, the lateral arm produces torque with which a contact part of the lever presses and deforms one of the elastic members to activate a corresponding one of switches S1 and S2. The activated switch outputs an imbalance detected signal to an adjustment unit, which resolves the imbalance. The switches S1 and S2 are simple to downsize the automatic balancing structure and are effective to carry out balance adjustment.
