PROBLEM TO BE SOLVED: To make the light of light-emitting bodies strike on an indication marked on an object, in the same quantity of light, uniformly and softly and to prevent the light from being affected by a shadow. SOLUTION: Light-emitting bodies 1 constituted of LEDs are so disposed as to be directed opposite to a printed matter. A semispheric cap 4 is put on the light-emitting bodies 1. A hole 5 for image pickup is provided in the top of the cap 4 and the reflectivity of light of the inside thereof is reduced moderately. Moreover, the light-emitting bodies 1 whereon the cap 4 is put are covered with a cover 6. Besides, a hole 7 wherein the cap 4 is held is provided in a main body part 6a of the cover 6, while a hole 8 having the same diameter as a light-passing hole 3 of a base 2 of the light-emitting bodies 1 is provided in a base plate 6b of the cover. |
