Abstract
A light emitting element array is provided with a plurality of light emitting diodes arranged in a row, field-effect transistors connected in series with the respective light emitting diodes, shift registers for individually turning the respective field-effect transistors on by individually supplying drive signals to gates of the respective field-effect transistors, and an emission controller for driving the light emitting diodes by supplying the emission signals, whose levels are so differed as to correspond to the respective light emitting diodes, to the light emitting diodes connected with the field-effect transistors when these field-effect transistors are individually turned on.
