PCT No. PCT/JP81/00375 Sec. 371 Date Aug. 5, 1982 Sec. 102(e) Date Aug. 5, 1982 PCT Filed Dec. 9, 1981 PCT Pub. No. WO82/02016 PCT Pub. Date Jun. 24, 1982.A device imparts a predetermined motion to an object by using a cam. The device comprises a load compensator disposed at any desired position in a driven section and adapted to apply a force or torque to the driven section in order to counterbalance variations in the force of contact between a cam and a cam follower. The variations are caused by the movement of the driven section. The force of contact is maintained at a constant value, and enables the achievement of stabilized high-precision motion of the cam driven system, particularly the achievement of high-precision high-speed machining of the lead on a VTR lower cylinder by using an end cam.
