ABSTRACT:
An X-ray diagnostic device with a suspension mechanism for suspending an object in a vertically movable manner, using two suspension wires, which can avoid the shortened durability of the suspension wires, and using windup type springs, which can eliminate possibility for the fall of the suspended object due to the breaking of the windup type springs. The suspension mechanism may includes two suspension wires for holding the suspended object; and single threaded corn pulleys, one for each one of the two suspension wires, for winding the respective suspension wires. The suspension mechanism may also includes a plurality of windup type springs for balancing against gravitational force acting on the suspended object; connection between the plurality of windup type springs such that this connection moves when the plurality of windup type springs are put to be not balanced with respect to each other; and mechanism for preventing the fall of the suspended object by detecting motion of the connection.
