Abstract

PURPOSE: To enable an object surface to be irradiated with light in any direction even if the surface is uneven or wrinkled, by providing the 1st reflex mirror closely to a lighting lamp nearly in parallel to its filament and the 2nd reflex mirror nearly at right angles.
CONSTITUTION: Around lighting lamp 4 with a rodlike filament, semicircular reflex mirror 5 is provided nearly in parallel to its filament for injecting light from lighting lamp 4 in the direction of arrow (b) of window postal matter 2 that has address information area 1 covered with cellophane. In front of both ends of lighting lamp 4, the 2nd reflex mirrors 8a and 8b are provided nearly at right angles to its filament to irradiate both end parts of the cellophane area in the direction of arrow (c) of windowed postal matter 2 by the light emitted from both ends of lighting lamp 4. Then, surface reflected light from address information area 1 is photodetected by a photodetector via a condenser lens to convert into an electric signal.
