Abstract

PURPOSE:To improve the reliability by ballancing the moment of the total weight applied on a mount table and the moment of the bias force of a spring around the rotary fulcrum of said table thereby statically ballancing said table at the random rotary angle position and enlarging the ballance range. CONSTITUTION:A rear foot 2 and a supporting foot 3 are provided on a mount table 1 where the supporting pole 5 and the supporting pole 5 of a base seat 4 are pivoted by a pin 6. A rod 12 has a supporting board 11 at one end and penetrates through a hole 8 in a tubular supporter 7 while the other end is fixed through a spring 14 to a disc 13. The supporting board 11 of said rod 12 is pivoted to the rear foot 2 of the mount table 1 by a pin 15 while the shaft 16 is inserted through a hole 9 of the tubular supporter 7. Said supporter 7 is supported rotatably by a supporting pole 5 where the shaft pin 17 can rotate together with tubular supporter 7.
