Driving circuit for a light-emitting element array

摘要

In an apparatus for driving a light emitting element array in which plural light emitting elements are aligned in a line, an analog shift register section having plural cells, shifts an electric charge having an analog amount corresponding to a density level of an image signal, plural converting elements each converts the electric charge into a voltage; and plural driving circuits each drives one of the plural light emitting elements in accordance with the voltage so that each light emitting element emits a light in an amount corresponding to the electric charge.
