Abstract An operation device (1) that is operated by a person includes a first condition in which the operation device (1) consumes a first amount of electric power; a second condition in which the operation device (1) consumes a second amount of electric power, the second amount being less than the first amount; a first detecting unit (600), to which electric power is supplied in the second condition, having a first detection range (Al) and detecting a person in the first detection range (Al); a second detecting unit (700) having a second detection range (A2) and detecting the person in the second detection range (A2), wherein the first detection range (Al) is wider than the second detection range (A2), and electrical power, required for the second detecting unit (700) to detect the person, is greater than electrical power required for the first detecting unit (600) to detect the person; a transmitting section (650) that transmits, when the person is detected by the first detecting unit (600) in the second condition, the electric power required for the second detecting unit (700) to detect the person to the second detecting unit (700); and an instructing section (740) that instructs, when the person is detected by the second detecting unit (700), the operation device (1) to change a condition from the second condition to the first condition.
