PURPOSE:To operate a working machine synchronously with the operation of a main machine drive system by providing a pulse encoder at a cam unit attached to the drive system. CONSTITUTION:When a cam unit 12 secured to the rotational shaft 11 of a main machine drive system is rotated synchronously with the drive system, a disk 21 is rotated through gears 16, 18, and a pulse encoder 30 outputs a pulse of approximate sinusoidal curve. This pulse is applied through a multiplier 30 and a thinning frequency divider 40 to a motor 50. A working machine 60 is driven by the motor 50. |
