More Information
Summary:The present invention uses LEDs as the light source in a optical printer employing a line scanning method in which an image is produced by relative motion of the light to a photosensitive medium. LEDs are arranged on a mounting substrate with LED pairs, each pair being of the same color, disposed symmetrically as to the center point of the line. Similarly, the power supply lead wires for the LEDs are also disposed symmetrically. In mounting the components on the mounting substrate, a light-intercepting material is used for intercepting light from the side faces of the LEDs.
