量検知センサー付原稿照明装置。[Scope of Claim for Utility Model Registration] 1. A bar-shaped light source is surrounded by a gutter-shaped mirror to illuminate the document surface in a band-like manner, and a part of this reflected light is received by an exposure detection sensor through a slit made in the mirror. A document illumination device that controls the amount of exposure based on the output signal of a sensor, characterized in that one edge of the upper opening of the case that receives the sensor protrudes halfway through the slit to narrow the slit width. A document illumination device with an exposure detection sensor. 2. The document illumination device with an exposure amount detection sensor according to claim 1, wherein the case is mounted movably in the width direction of the slit, so that the slit width can be adjusted.
