Abstract
PURPOSE: To make it possible to arrange a fluorescent lamp in the vicinity of the surface of an original, while making effective use of the quantity of the emitted light, by providing a transparent portion, which allows the optical bundle of a focused image to pass therethrough, at the fluorescent lamp.
CONSTITUTION: A rectangular fluorescent lamp 13 is arranged just below an original carriage 10, below which is arranged in parallel such a shielding plate 11 as has a slit 12 for allowing the optical bundle of a focused image to pass therethrough. The fluorescent lamp 13 is formed with a reflecting layer 17 and a fluorescent layer 18 inside of a glass tube 16 and with such transparent portions 14 and 15 at the upper and lower facing sides as also allow the optical ray of the focused image to pass therethrough.
