装置。[Scope of Claim for Utility Model Registration] 1. In an image recording device that irradiates a document with linear light and scans and records image information obtained by irradiating the linear light through an imaging optical system, A light guide optical fiber is disposed between the document placement section and the light source section, and the input end of this optical fiber is placed facing the light source, and the output end is placed near the document placement section and directed toward the document. arranged in rows,
A document illuminating device for an image recording apparatus, characterized in that the optical fiber arrangement density at the output end is configured such that the density increases sequentially from the center toward both ends. 2. It is equipped with a light source section having a color correction filter unit and a light mixer, and a light guide optical fiber arranged between the light source section and the document placement section, and the incident end of the optical fiber is arranged between the light source section and the document placement section. The light source section is arranged so as to face the light mixer, and its output end is arranged in a row close to the document placement section, so that the document is illuminated with color-correctable linear light. A document illumination device for an image recording device characterized by:
