Abstract
A self-scanning light-emitting element array is disclosed. A coupled array of light-emitting elements is constituted so that a light-emitting element which is turned on influences a light-emitting element to be turned on next so that its threshold level is changed. When each element is clock-driven by a common drive pulse, the change in threshold level is shifted in the array direction, so that a turn-on operation is transferred in a clock period of the drive pulse.
