ABSTRACT:
The improved image recording apparatus scans a transmission-type original with light from a light source and allows the light through the original to be focused on a light-receiving material by means of an imaging lens. The apparatus comprises the light source, a lens or a mirror that converge or collimate the light from the light source, and a lens or a mirror that have more one focus and that are placed in the optical path between said light converging or collimating lens or mirror and the transmission-type original. The apparatus is capable of so efficient utilization of light as to have a sufficient quantity of the transmitted light fall on the entrance pupil of the imaging lens and is capable of recording high-quality images that render the dust buildup or other flaws on the transmission-type original less noticeable.
