An actuator drive unit in which either of two types of actuators and a drive direction thereof (either forward direction or backward direction) are corresponded to respective four pistons. When one of the four pistons in one of four displacement signal generating units generates a displacement signal, the actuator corresponding to the piston generating the displacement signal is driven in a corresponding drive direction, by an amount of drive corresponding to the displacement signal.
