Abstract: An input operation device according to the present disclosure includes first to third light-emitting sections, a first light guide body, and a second light guide body. A lower end of the first light guide body faces the first light-emitting section and the second light-emitting section. The first mark emits light on the first light guide body when light is incident on the first light guide body from the first light-emitting section, and the second mark emits light on the first light guide body when light is incident on the first light guide body from the second light-emitting section. The upper surface section of the second light guide body emits light when light is incident on the second light guide body from the third light-emitting section. At least one of the first light-emitting section, the second light-emitting section, and the third light-emitting section can change light emission luminance.
