A controller 102 capable of transmitting and receiving an input signal from a drive circuit corresponding to a moving device, a mounting head, or the like of an electronic component mounting machine or an output signal to the drive circuit for each predetermined period (A/2), in which the controller 102 computes an output signal based on an input signal which is received before the predetermined period, stores the output signal for a time greater than or equal to the predetermined period, and subsequently transmits the output signal to the drive circuit. Accordingly, it becomes possible to compute an output signal using a long time, and it becomes possible to adopt a servo controller with low computational capabilities. It becomes possible to set a time (a delay time) from when an input signal is output until an output signal reaches a drive circuit to an arbitrary length by adjusting the storage time. Accordingly, for example, it becomes possible to render the delay times of controllers with different control periods the same, and it becomes possible to render actuation timing or the like of actuator devices of each controller the same.
