1. An inspecting apparatus for reading print images printed on a transparent printing medium and inspecting printing states, the apparatus comprising:
a first transport roller for transporting the transparent printing medium;
a second transport roller spaced from the first transport roller without a configuration for supporting the transparent printing medium being provided between the first transport roller and the second transport roller, the second transport roller being disposed downstream from the first transport roller in a transport direction, for transporting the transparent printing medium;
a photographing device disposed between the first transport roller and the second transport roller, and opposed to one surface of the transparent printing medium, for photographing the print images located in an inspection area set between the first transport roller and the second transport roller; and
a light emitting device for emitting light for the photographing device to photograph the print images located in the inspection area, and including at least a transmitted light source located opposite the photographing device across the transparent printing medium,
wherein the first transport roller and the second transport roller have outer circumferential surfaces thereof each with a light absorbing member for absorbing the light from the light emitting device.
