PURPOSE:To provide a stand device preventing the link member supporting optical machinery for medical treatment from largely oscillating during operation and requiring no horizontal adjustment. CONSTITUTION:A crank member 34 is pivotally supported on a connection shaft beta1 and the horizontal fulcrum beta6 of the crank member 34 is connected to a part beta8 of a stand 18 by a vertical sub-link 37 and the vertical fulcrum beta7 of the crank member 34 is connected to a part beta9 of a leading end crank 27 by a horizontal sub-link 38 and, therefore, the leading end link 27 supporting optical machinery 33 for medical treatment is always held to an almost vertical state. As a result, since it is prevented that the leading end link largely oscillates to hit the peripheral person, this stand device is suitable in operability and the aspect of sanitation. |
