In a cellular phone, a light guiding plate, which linearly guides light emitted by a plurality of light emitting elements (LEDs), and an LED display unit, which displays predetermined LED displays, are laminatedly arranged in a movable-side housing. A slit formed in the substantially central portion of the light guiding plate partitions the light guiding plate into a first light guiding region and a second light guiding region. A first light emitting group of the light emitting elements emits light to the first light guiding region and a second light emitting group of the light emitting elements emits light to the second light guiding region. The first light guiding region and the second light guiding region are illuminated alternately by alternately switching ON the first light emitting group and the second light emitting group.
