Abstract: PURPOSE:To weaken springs for vertical motion and lateral motion to lighten drive systems for vertical motion and lateral motion by providing springs for vertical motion in a shaft at two positions in right and left to give the spring force to the shaft at two positions right and left. CONSTITUTION:Springs 51, 53 for vertical motion are provided in a shaft 11 at two positions right and left. A contact point provided in a Z-shaft driving lever 23 abuts on a right and a left wing parts of the shaft 11 from the lower side, and furthermore, in the upper side of the wing parts, the spring force is made to resist the drive force of the Z-shaft, on which the contact point of the springs 51, 53 provided in the shaft 11 at two positions right and left abuts, to take a balance. Since the spring force can be weakened by providing the springs 51, 53 in the shaft at two positions right and left, the whole of the Z-shaft drive system is made compact and lightened. Since the frictional resistance at the time of lateral motion can be reduced, the drive system for lateral motion can be made compact.
