Claim 14:
15. The light emission control device according to claim 12, further comprising a fault detector configured to detect a fault in any of the light-emitting elements in the light-emitting element array based on a voltage at a connection node between the light emission control device and each of the light-emitting elements in the light-emitting element array,
wherein the controller is configured such that,
in the second mode, when the fault detector detects a fault in any of the light-emitting elements in the light-emitting element array, the controller extinguishes all the light-emitting elements in the light-emitting element array with priority over the second driving sequence and holds an electrical potential at the clock terminal at a predetermined electrical potential, and
in the first mode, when the electrical potential at the clock terminal is held for a predetermined length of time or longer, the controller extinguishes all the light-emitting elements in the light-emitting element array with priority over the first driving sequence.
