Patent ID: 7665856

Claim:
An imaging device comprising: a camera unit for imaging an area of a table on which an imaging-object is to be mounted, and an illumination unit for illuminating a table upper face during imaging, wherein the illumination unit includes: a plurality of light sources composed of light emitting diodes disposed as a light source array on a base plate such that light will be directed onto the table upper face, with the plurality of light sources being positioned on the base plate such that, in a center light source array zone and in light source array zones to left and right of the center light source array zone of the light source array, a placement frequency of the light sources in the left and right light source array zones is higher than a placement frequency in the center light source array zone; end reflector plates projecting from the base plate and adapted to reflect towards the table upper face light that is emitted towards outside of the table upper face by light sources situated at ends of the left and right light source array zones; and center end reflector plates projecting from the base plate at ends of the center light source array zone and adapted to reflect towards the table upper face light that is emitted towards outside of the table upper face beyond a table center zone of the table upper face by light sources situated outside of the center light source array zone.
