Abstract

A drive unit changes an irradiation direction of irradiation light from a light-emitting portion. A setting unit sets the irradiation direction of the irradiation light from the light-emitting portion. A control unit controls the drive unit. Depending on a cause of which the irradiation direction of the irradiation light from the light-emitting portion changes from the irradiation direction that is set by the setting unit, the control unit changes responsiveness of the drive unit that changes the irradiation direction of the irradiation light from the light-emitting portion into the irradiation direction that is set by the setting unit.
