Abstract:
In a display control system (100), a reading apparatus (10) is provided with a light source (14), and an image pickup optical system (15) that picks up an image of light outputted from the light source (14) and reflected by a display panel (24), and the display panel (24) is provided with an information pattern layer (40) having an information pattern (3) formed therein, and a reflecting layer (48), which is disposed on the rear surface side of the information pattern layer (40), and which diffusely reflects light outputted from the light source (14). The light source (14) is disposed at a position excluding a position on an optical axis of the image pickup optical system (15). In a state wherein the optical axis of the image pickup optical system (15) is perpendicular to the reflecting layer (48), and the reading apparatus (10) is in contact with the display panel (24), a point where a central ray of the light outputted from the light source (14) reaches the reflecting layer (48) is positioned further toward the light source (14) side than a point where the optical axis of the image pickup optical system (15) and the reflecting layer (48) intersect each other.
