PENDULUM TYPE OPTICAL PATH AUTOMATIC COMPENSATING MECHANISM OF SURVEYING MACHINE AND SUSPENDING METHOD FOR PENDULUM BODY

摘要

PURPOSE:To facilitate suspension wire connecting operation by using two suspension wire materials and engaging holes of the suspension wire materials with engagement projections of a fixed frame body and the pendulum body. CONSTITUTION:The fixed frame 22 and the bottom part 24a of the pendulum body are arranged vertically at a specific distance and the fixed frame 22 and bottom surface part 24a are fixed in this state. Then a hole of the suspension wire 40 on its end part side is engaged with the engagement projection of the fixed frame 22 from below the bottom surface part 24a. Then while the suspension wire 40 is drawn downward, a washer 46 is arranged around the engagement projection projecting from the hole of the suspension wire and the wire is engaged threadably with a fixing screw 48. Thus, the suspension wire operation of the pendulum body 24 is facilitated.
