摘要:
At least one light emission array (7) includes a plurality of light emitting elements (Ea) arrayed in a first direction. Each of the light emitting elements (Ea) is an organic electroluminescence element. A controller (8) performs a constant voltage control with respect to the light emitting elements (Ea). A current detector (5) collectively detects a drive current flowing in each of the light emitting elements (Ea). A checker (3) checks light emitting characteristics of at least one of the light emitting elements (Ea) in accordance with the detected drive current.
