PROBLEM TO BE SOLVED: To properly control drive of loads while simplifying a structure. SOLUTION: In this controller, a microcomputer 10 has a CPU 11, an EEPROM 12 and timer modules 13, 14. The CPU 11 controls the drive of a stepping motor 20 through the timer module 13, and controls the drive of lamps 41, 42 through the timer module 14. The stepping motor 20 is composed of a four-phase motor and has motor coils 21, 22, 23, 24. Filter circuits 31-34 are provided between the microcomputer 10 and the stepping motor 20 correspondingly to the respective motor coils 21-24, and filter circuits 35, 36 are respectively provided between the microcomputer 10 and the lamps 41, 42. The microcomputer 10 outputs load control signals having different frequencies in the respective loads such as the motor coils 21-24 or the lamps 41, 42, and controls the drive of the loads through the filter circuits 31-36.
