Abstract:
1. A light-emitting element chip, comprising: a substrate; a light-emitting thyristor array that is formed on the substrate, and that has a plurality of light-emitting thyristors controlled whether or not to emit light; a light-emission control thyristor array that is formed on the substrate, and that has a plurality of light-emission control thyristors connected respectively to the plurality of light-emitting thyristors, the plurality of light-emission control thyristors respectively specifying, as a target for controlling whether or not to emit light, the plurality of light-emitting thyristors to which the plurality of light-emission control thyristors are connected respectively when being sequentially turned on in order to be in an on state; and a light-emission enable thyristor that is formed on the substrate, and that is connected in parallel to the plurality of light-emission control thyristors, the light-emission enable thyristor preventing any of the plurality of light-emission control thyristors being in an off state from transitioning from the off state to the on state, when the light-emission enable thyristor is turned on in order to be in the on state.
