Claim 6:
7. A control method comprising:
a control step of controlling a plurality of irradiation devices that emit electromagnetic waves,
wherein in the control step, a plurality of first periodic signals for respectively controlling movements of irradiation directions of the electromagnetic waves to a first direction in the plurality of irradiation devices, and a plurality of second periodic signals for respectively controlling movements of the irradiation directions of the electromagnetic waves to a second direction in the plurality of irradiation devices are output,
wherein periods of the plurality of first periodic signals are the same as each other,
wherein in the control step, the second periodic signals for a plurality of periods are output during the first periodic signals for one period are output,
wherein effective repetition numbers of movement of the irradiation directions to the second direction while the irradiation directions are moved one period to the first direction are the same for the plurality of irradiation devices,
wherein a difference in the effective repetition numbers of the second periodic signals before a reference point in each period of the first periodic signal is less than 1 between the plurality of irradiation devices, and
wherein the electromagnetic wave is not emitted from the irradiation device during a time of movement to the second direction that is not counted as the effective repetition number.
