Claims

[Scope of Claim for Utility Model Registration] (1) Distributed radially from the center of the object on the scanning line of the camera before and after the scanning line of a color sensor camera installed above the conveyor conveying the object to be imaged. A large number of lamps are placed on a mounting base along an extension line of the imaged object so that the distances from the center are approximately equal, and the lamps are placed between the lamps and the object. 1. A measurement illumination device, characterized in that a diffuser-transmitting plate that diffusely transmits light from the lamp is provided along the arrangement of the lamp in a direction substantially perpendicular to the optical axis of the lamp. (2) The measurement lighting device according to claim 1, wherein the mounting base has a mounting portion for the lamp and a reflective surface on an inner surface.
