Abstract

An image recording apparatus has a plurality of print engines aligned along a transport path in which a recording medium is transported. Each of the plurality of print engines records a corresponding toner image on the recording medium. The apparatus includes a plurality of rows of LED arrays each of which includes a plurality of LED arrays and is assembled in a corresponding one of the print engines. Each of the plurality of rows extends in a direction substantially perpendicular to the transport path and illuminates a surface of a photoconductive drum in a corresponding print engine, and forms an electrostatic latent image on the photoconductive drum. The plurality of rows are staggered such that a following one of the rows of adjacent print engines is a predetermined distance ahead of a preceding one of the rows of the adjacent print engines.

Claims3

Dependent claims

An image recording apparatus, comprising:

a plurality of image-forming sections that record corresponding toner images on a recording medium in register;
a plurality of exposing units each of which is mounted to a corresponding one of said plurality of image-forming sections;
and
a plurality of rows of arrays of light-emitting elements, each of said plurality of rows being mounted to a corresponding one of said plurality of exposing units, each of said plurality of rows having a plurality of light-emitting elements and being aligned straight in a direction in which the plurality of light-emitting elements are aligned;
wherein adjacent rows are staggered so that adjacent endmost light-emitting elements of adjacent arrays in a preceding one of the adjacent rows are a predetermined distance ahead of corresponding adjacent endmost light-emitting elements of the adjacent arrays in a following one of the adjacent rows.
