An activator activates a power source when a rotation angle of the rotary member is increased to a first specific angle belonging to the first angle range. An adjuster adjusts a setting of an optical system with reference to a rotation of the rotary member in the second angle range. A notifier generates a notification when the rotation angle of the rotary member remains within the first angle range in a state where the power source is activated.01-24-2013
