Abstract:
1. An image inputting device comprising: a carrying unit to carry an object along a specified carrying direction that passes through a radiating area and a non-radiating area located downstream in said carrying direction with respect to said radiating area, the object having a marking pattern comprising a phosphorescent material or a fluorescent material; a light radiating unit to radiate light toward said object being carried by said carrying unit to make said marking pattern emit at least phosphorescence or fluorescence; a light radiation limiting unit to limit light radiation from said light radiating unit toward said non-radiating area; and an image detecting unit to detect an image by receiving the fluorescence or the phosphorescence emitted from said object, said light radiation limiting unit comprising a light-blocking plate to block light emitted from said light radiating unit toward a field of view in said non-radiating area, wherein, when the phosphorescence is emitted from said object in said non-radiating area, said image detecting unit detects the image by receiving the phosphorescence.
